Item #: SCP-854
Object Class: Safe
Special Containment Procedures: SCP-854 is contained on US Bureau of Land Management property in ████████ state. Roads and trails leading to the site have been closed for “maintenance” and rendered impassable, while cameras monitor the site and all approaches to it. Supervising personnel are authorized to use any nonlethal means to deter trespassers.
Barriers erected at the ends of the arch prevent access except under controlled circumstances. Wild animals are not permitted in the area in order to prevent unsupervised disappearances.
Description: SCP-854 is a natural arch formation eroded from sandstone in ████████, ██ and known locally as the “Dream Bridge”. Despite its precarious appearance it is exceptionally stable and can support in excess of 400 kg without difficulty. A single large pictogram in an unknown language adorns the base of the structure, but it is otherwise naturally formed.
The arch has no observable anomalous properties unless the top is traversed, like a bridge, from East to West. Animals and people crossing from West to East, walking under or around the formation, or otherwise interacting with it in any other way experience nothing out of the ordinary.
Living animals that cross the arch from East to West vanish at the midpoint of the structure. No organism that has disappeared has ever been recovered. Contact with the arch is necessary for this phenomenon, as birds flying above it in the same direction experience no effects. Nonliving items, such as remote controlled vehicles, also cross without interruption.
No energy discharge, spatial irregularity, or other ancillary phenomenon has been detected that explains the mechanism of the disappearances. Eyewitnesses and sensor recordings suggest that subjects simply cease to exist the moment they reach the halfway point atop the arch. Recording equipment carried by or attached to test subjects vanishes along with them, halting any transmissions.
Local lore ascribes various supernatural properties to the arch and its environs. Usually the arch is depicted as a gate or bridge to another realm, often spiritual in nature, which must be venerated or guarded. Certain oral traditions state that those who cross the bridge are granted an audience with "Mother Sky", a local divinity figure. In past times of need, a messenger would brave the journey to bring news of her people's plight and a gift to sway her will. Whether the messengers carried the gift with them or were, themselves, the gift varies based on the account.
Capture summary: The “Dream Bridge” arch formation has a history of anomalous stories and myths related to it, but was not examined by the Foundation until 19██. An amateur vacation video filmed by Nancy ███████ of ███████, ██ showed a ground squirrel being chased by the family dog across the arch, with both vanishing in mid-stride at the center. The video was played on local news channels before being explained as a trick of the lighting and recovered by Foundation agents.
Other than the aforementioned disappearances, no abnormal properties attributed to the site in folklore have ever been verified by the Foundation.
Incident Report 854-01: On February 18th 20██, a radiolabeled Foundation tracking tag was intermittently detected 200 km SW of Nord, Greenland by satellite systems. A recovery team located and collected the device, which lay exposed on a remote hilltop. The team also collected 3 metal zippers, 35 brass buttons, a variety of crushed electrical components, 2 gold tooth fillings, hundreds of flint and obsidian axe heads, spear points, and carvings, and a pair of metal pet tags from the same location. The tracking device was identified as one used in Foundation experiments with SCP-854 in 198█. No further items sent through SCP-854 have appeared at this location, perhaps due to some time delay phenomenon. Experiments and observations are ongoing.

SCP-855 before development of anomalous properties.

Item #: SCP-855
Object Class: Euclid
Special Containment Procedures: Four (4) members of security are to be present outside SCP-855's location at all times. No staff are to enter SCP-855 during "Horror", "Surreal", "Action", "Science Fiction" or "Disaster" phases. Any entities attempting to leave SCP-855 during the "Horror" phase are to be dispatched by security staff.
Any personnel entering SCP-855 during its "Western" phase are to be monitored by security staff for signs of aggression. During all other phases, research staff are free to enter and monitor SCP-855.
Description: SCP-855 is the designation given to Lecture Hall ██, located at Site ██. SCP-855 is equipped to seat one hundred (100) personnel. One reinforced skylight is present on the ceiling to allow the entry of natural light.
Each month, SCP-855 will redecorate itself and temporarily develop anomalous properties, seemingly themed after genres of film. This continues for the entirety of the month, and has taken the form of:

Manifestation of entities

Presumed 'Genre'
Effects

January
Action
Reports of explosions came from within SCP-855. Security was called in to investigate, at which point a sports car burst through the doors into SCP-855, running over one (1) member of security. Personnel later reported a man in a tuxedo firing at them with a pistol from within the vehicle. Vehicle vanished thirty (30) seconds later.

February
Detective Noir
Researchers within SCP-855 temporarily adopted a pessimistic attitude. Light spectrum appears to be affected, causing all researchers in SCP-855 to turn monochrome.

March
Surreal
All researchers sent into SCP-855 disappeared without a trace. Mobile Task Force Beta-23 ("Film Critics") was sent in for a retrieval mission. One member of Mobile Task Force Beta-23 was recovered twenty (20) days after entry, the rest were declared KIA. Survivor claims that SCP-855 contained a room that stretched on for miles, with 'things' in it. Survivor did not respond to further inquiry regarding the nature of said entities.

April
Comedy
Rate of research accidents surrounding SCP-855 increased by 50%. Multiple personnel reported disembodied laughter.

May
Western
Increased aggression noted in personnel inside SCP-855. Multiple fights break out. After researchers were evacuated, the doors leading into SCP-855 opened independently, at which point a single tumbleweed emerged.

June
Disaster
All personnel evacuated from SCP-855. Analysis of SCP-855 via camera drone shows dangerously high levels of radiation. Large, ratlike creature detected by camera drone.

July
Gangster
Footage camera drone used to monitor SCP-855 showed a large city similar to 1950's Chicago. Every individual on the street appeared to be dressed in the manner of a stereotypical gangster.

August
Drama
Upon entering SCP-855, researchers became highly aggressive and began insulting and arguing with those nearby.

September
Science Fiction
Entry to SCP-855 was strictly forbidden, as sensors indicated no oxygen was present within.

October
War
Sounds of conflict were audible from within SCP-855. Security were called in to prevent a repeat of the "Action" incident. A World War 2 era tank subsequently emerged from SCP-855 and fired upon security, killing three (3) of them. Said tank vanished thirty (30) seconds later.

November
Historical
Recording from camera drone sent into SCP-855 showed a portrayal of Rome at the height of the Roman Empire. Further analysis revealed several historical inaccuracies, as all individuals were observed to speak clear English, some with obvious accents.

December
Horror
A heavy-set man with a noose around his neck emerged from within SCP-855, wielding a large knife. ██ personnel killed during partial containment breach. Security later reported that bullets had little effect on the entity.

« SCP-854 | SCP-855 | SCP-856 »


Item #: SCP-856
Object Class: Euclid
Special Containment Procedures: The affected length of the █████████ River is bounded with four kilometers of chain link fencing, three meters in height and topped with razor-wire. The fence lines both banks and connects across the river at both ends of the containment area. Signs are posted every fifty meters in Arabic and English, warning of a chemical spill contaminating the river. Two armed guards are sent twice daily to patrol both banks of the containment area in a standard Foundation off-road vehicle. The vehicle is equipped with a .50 caliber rear-mounted machine gun for use in the event of a containment breach.
Should a civilian(s) accidentally come into contact with SCP-856, they are to be treated with a Class-B Amnestic (if still alive) and transported immediately to the hospital in Rumbek. Medical staff are to be told the victim suffered from an unknown animal attack. The use of force is acceptable if a civilian(s) deliberately attempts to come into contact with SCP-856.
Description: SCP-856 is an entity residing in a four kilometer length of the █████████ River in southern Sudan. If a human being comes into contact with the water, SCP-856 appears virtually instantaneously and attempts to attack them.
SCP-856 appears to be leonine in nature. Estimations put the entity at approximately the size of an adult male lion (Panthera leo). SCP-856 seems by all evidence to be bound to the river, as it has rarely been witnessed extending itself out of the water or beyond the banks by more than 1.5 meters (Note: see Incident Log).
Attacks come variably upon bodily contact with the river. In the majority of cases, SCP-856 appears within several seconds. However, in certain instances, the entity has appeared to time its attacks for maximum efficiency. If multiple parties come into contact with the water, SCP-856 will jump between individuals in fractions of a second, entirely regardless of distance. The entity's ability of instantaneous movement does not apply to water up- or down-river of the containment area, or water physically detached from the confines of the river itself. Despite the abnormal capacity for movement exhibited by SCP-856, its attacks are of normal velocity and can be avoided with sufficient alertness.
Factors that incite attacks appear to be variable. No amount of protective clothing appears to prevent SCP-856 from sensing the contact of humans with the river. Objects placed in contact with the water by human beings have likewise provoked attacks, save for certain instances conducted with extreme care. Fauna in contact with the river generally do not incite attacks from SCP-856.
SCP-856 causes deep incisions and lacerations consistent with leonine teeth and claws. Wounds are fatal in 50-60% of cases, and generally come to the throat, face, or upper torso.
SCP-856 by all accounts ceases to exist when not attacking. Extensive photography, satellite surveillance, and sonar sounding have failed to observe the presence of SCP-856 in the absence of a provoking party.

Historical note:
Foundation control over SCP-856 and the four kilometer section of the █████████ River was minimal between the discovery of the site in 1956 and the Sudanese ceasefire of 1995. At that point, greater numbers of personnel could safely enter the area and current containment procedures were put into effect.
Prior to 1995, a small village of several hundred people, called ███, was situated on the eastern bank of the █████████ River within the region containing SCP-856. The inhabitants of the village were inexplicably able to draw water from and wash in the river without inciting attacks. Interviews revealed that the villagers believed the entity was a protective spirit, and ritualistically left it offerings of livestock. In 1995, a joint effort between Foundation forces and UN peacekeeping troops re-situated the village 9 km downriver with a minimal loss of civilian life.

Relevant Incident Logs:
Incident 856-A
Date: ██/██/1956
Events: A troop of twenty-one Anya-Nya guerrillas attempted to ford the river from the west bank, apparently with intent to attack ███ Village. Eyewitnesses claim that when the party was approximately halfway across the river, SCP-856 sprang upon them from down-stream. Three of the soldiers were killed and several more were injured within thirty seconds. Wounds inflicted on SCP-856 by gunfire appeared to harm it without consequence ("It bled but never stopped"). The remaining men fled from the area.
Notes: Reports of this incident led to the first investigation of SCP-856 by the Foundation, and the establishment of rudimentary containment procedures.
Incident 856-B
Date: ██/██/1971
Events: A surveying motorboat drifted within the section of the river containing SCP-856, resulting in the deaths of two junior researchers. The first was killed by a laceration to the throat, and the second expired later due to blood-loss from a severed limb. The researchers were members of a three-week task force sent to gain further information on SCP-856 through observation and experimentation.
Notes: Following this incident, extant containment procedures for SCP-856 were intensified.
Incident 856-E
Date: ██/██/1995
Events: A team of five engineers were attacked while attempting to lay a temporary bridge over the section of river containing SCP-856. One suffered fatal injuries.
Notes: Security footage confirms that at no time did any personnel or bridge component come into contact with the water. It appears that under certain circumstances, SCP-856 is able to leave the confines of the river.
Incident 856-F
Date: ██/██/2009
Events: Due to a particularly bad drought, a section of the █████████ River, including the containment area for SCP-856, dried up for a period of 42 hours. At 08:30 in the nearby city of [DATA EXPUNGED]. All three entities were finally pushed back by Foundation forces at 13:50. Total deaths numbered 22 civilian, 9 local law enforcement, 1 Foundation personnel.
Notes: This incident has called into question Foundation understanding of the exact composition of SCP-856. It has been ascertained from this incident that with significant firepower, SCP-856 can be restrained for a short period of time. Requests have been filed for measures to prevent further incidents of this type.

Exterior of SCP-857. No specimens visible.

Item #: SCP-857
Object Class: Safe
Special Containment Procedures: The area designated SCP-857 is to be surrounded by electrified fences measuring two (2) meters in height. Any civilians attempting to enter SCP-857 are to be brought into custody and interrogated. After interrogation, intruders are to be dosed with a Class-A amnestic.
No specimens of SCP-857-1 are to be allowed to leave SCP-857.
Description: SCP-857 is a section of the Amazon Rainforest measuring one square kilometer. Plants native to the region grow normally in this area, but animal life appear to instinctively avoid it. SCP-857 is populated entirely by what appears to be human organs and body parts capable of ambulation and basic thought.
The source of these specimens are currently unknown, and they will hereafter be referred to as SCP-857-1.
Specimens of SCP-857-1 are non-hostile towards humans and vary wildly in form and function. (See Specimen Log 857.) These mobile body parts appear to have been crudely altered to allow for movement and consumption of food. For example, most specimens do not possess an actual working mouth, but a large artificial orifice in the flesh that superficially resembles a mouth. The method by which specimens of SCP-857-1 digest food is currently unknown.
Although SCP-857-1 are naturally incapable of reproduction, no decrease in the number of observed specimens has been noted. Exploration is currently underway in an effort to discover the source of SCP-857-1.

Descending cloud formations affected by SCP-858

Item #: SCP-858
Object Class: Keter
Special Containment Procedures: Three samples of contaminated precipitation are to be maintained within a storage locker in the Infectious Wing of Research Site-██. Reports of "cloud iridescence" are to be tracked until the likely area of precipitation can be identified and evacuated. Cover stories involving tornado activity are to be prepared and distributed afterwards, with area cleanup to consist of evaporation of contaminated water via heat lamp.
Objects and subjects affected by SCP-858 are to be detained and destroyed on-site, incinerated, and their remains allowed to escape Earth orbit.
Description: SCP-858 is a migrating noctilucent cloud which affects cirrus cloud formations beneath it. Presence of SCP-858 can be easily identified by the iridescent refraction within the cirrus formations, which, once affected, descend until precipitation ensues. Contact with precipitation from affected clouds immediately and permanently alters solid matter on contact. While apparently nonreactive with gasses and liquids, solid state reactions cause the molecular bonds of affected items to act as a vector, conducting the effect until the entirety of affected objects or organisms is repelled by, rather than attracted by, gravitational force. Porous materials act as a secondary vector, as affected water trapped in the substance in no way loses its effectiveness1. Barring sufficiently sturdy objects secured to sufficiently massive objects embedded or otherwise secured to Earth's surface, this results in the affected object accelerating away from the Earth's surface at 9.8m/s2. Upon contact with SCP-858 itself at roughly 80km above sea level, affected objects vanish.
Encounter Summary 858-A: First encounter with SCP-858 was a meteorological survey aircraft passing through an affected cloud formation. When the aircraft was affected by SCP-858, the pilot, Captain █. Finch, was able to invert the aircraft and maintain flight for several hours; when the plane proved unable to land, Captain Finch instructed the crew to bail out. He then continued to fly the affected aircraft until it ran out of fuel, at which time he abandoned the craft and it entered free-fall- away from the Earth's surface. Captain Finch contracted hypothermia and frostbite due to the severe altitude at which he bailed out, but he has since made a full recovery.
The plane's lateral velocity was sufficient to carry it past the boundaries of SCP-858. Later reports indicated forced emergency maneuvers on the part of a Russian satellite in the trajectory of the plane's debris. No other objects have been detected passing the Kármán line2.
Finch's descriptions of the oddly colored cloud formations and their location led researchers to what remained of a small farming community outside of Xenia, Ohio. After Finch later forwarded his airline's incident report- in which the instruments showed the plane leaving Earth's atmosphere before failing completely- to a Foundation agent, an investigative team was dispatched to the location. The vehicle in which the team of six arrived was lost upon contact with damp road surfaces, but after leaping free of the vehicle, losses among initial responders were prevented, as the mass of responder hazmat suits were insufficient to overcome their occupant's weight.
Investigation revealed all previously standing structures were devastated and, along with all residents outside of cellar shelters with strong foundations, unaccounted for. Most survivors were initially unwilling to leave their cellars when responders arrived, though a family of three was lost when their footwear was saturated while crossing their lawn to greet the response team. Reports from remaining survivors aided in isolating standing water as the source of the anomalous effect, as eyewitness reports stated that survivors emerging from their basements were seen rapidly ascending into the sky, later ascertained to have been due to assuming the danger had passed once there was nothing left to ascend- rainfall was continued. Even after precipitation ceased, other vehicles arriving after the fact continued to be affected- though the tires themselves were insufficient to displace the chassis, water sprayed onto the undercarriage by centripetal force compromised the vehicles in their entirety. Those persons able to exit their vehicles were inevitably suffered the same fate- regardless of whether they survived impact or not- as without the protection the responder's hazmat suits offered, they were affected by, and lost to, SCP-858 on contact with still-wet ground surfaces. Remaining survivors were extracted following natural evaporation of the anomalous precipitate, and were treated with amnestics before being released to their surviving relatives.
Addendum: Proposals to investigate SCP-858 itself have been stymied by the extreme expense of reaching the 80km altitude of the cloud; however, plans for altering the maneuvering thrusters of a geostationary satellite- soon to be launched by Foundation front company, ██████████ Corporation- to compensate from gravitational drift away from the planet, rather than towards it, is under consideration, pending calculation of the launch date and location in concert with the position of SCP-858.

Footnotes
1. Saturation of footwear via droplets contaminating lawn surfaces has been confirmed sufficient to affect the wearer; see Encounter Summary 858-A for an example.
2. The Kármán line is generally used to define the point at 100km from Earth at which outer space is considered to begin.

« SCP-857 | SCP-858 | SCP-859 »


Item #: SCP-859
Object Class: Euclid
Special Containment Procedures: SCP-859 is stored in a locked container, which is stored in a secure containment chamber at Site ██. SCP-859 must not be removed from its container except with express permission from Level 4 personnel, and experimentation on SCP-859 must only be performed with Class D personnel.
Description: SCP-859 is a spherical mass of dark, unidentified material approximately 11cm in diameter that appears to be covered in multiple layers of spider webbing. SCP-859 is soft to the touch, and approximates the stickiness of spider webbing, although the strands observed on the object do not come off.
When any living human places their hand on SCP-859, the subject immediately gains an acute arachnophobia as well as severe allergic reactions to any kind of spider venom. See Addendum 859-1 for details.
SCP-859 was discovered in [DATA EXPUNGED] along with the swollen and decayed bodies of 37 individuals who had been [DATA EXPUNGED]. Investigation into the origin of SCP-859 as well as the exact nature of its effect are inconclusive.
Addendum 859-1:
List of personnel exposed to SCP-859:
Subject: Agent █████████
Date: ██/██/20██
Exposure Method: Accidental, during containment of SCP-859. Subject immediately screamed and dropped SCP-859 after touching it with his bare hand. When questioned afterwards, reported that he saw hundreds of venomous spiders crawling out of SCP-859 and onto his hand. No spiders were observed in the area, and acute arachnophobia was observed in Subject.
Result: Subject was found dead in his apartment on ██/██/20██, having died from a bite from a common house spider. Subject had no history of being allergic to spider venom according to medical profile from Foundation records.
Subject: D-47121 - male African-American, 31 years old, no known medical allergies
Date: ██/██/20██
Exposure Method: Instructed to place hand on SCP-859. Displays shock and revulsion to SCP-859 after contact, similar to initial case. Acute arachnophobia observed in Subject.
Result: After showing violent resistance and extreme terror when attempting to expose Subject to an agitated huntsman spider, Subject is restrained and spider placed on Subject. Subject bitten and immediately exhibits symptoms of extreme anaphylactic shock. Subject dies within 1 minute of exposure, and attempts at resuscitation result in failure.
Note: Huntsman spiders have particularly mild venom, rarely resulting in little more than mild pain.
Subject: D-47565 - female Caucasian, 27 years old, no known medical allergies
Date: ██/██/20██
Exposure Method: Instructed to place hand on SCP-859. Subject exhibited significant resistance prior to instructions. Similar initial symptoms to previous subjects.
Result: Subject restrained and exposed to agitated huntsman spider. Emergency medical treatment administered immediately after Subject is bitten, including epinephrine. Medical treatment has no effect, Subject dies within 1 minute of exposure.
Subject: D-47901 - male Asian, 29 years old, no known medical allergies
Date: ██/██/20██
Exposure Method: Instructed to place hand on SCP-859. Subject exhibits regular initial symptoms, after which Subject is placed in secure isolation chamber, with measures to prevent any insects from breaching isolation.
Result: Subject exhibits increasing levels of paranoid arachnophobia, peaking after five (5) days in isolation, after which Subject is observed semi-catatonic, curled into a fetal position in the corner of the chamber, and constantly babbling and muttering about "spiders on the walls", and "they're coming to get me". Subject found dead of severe allergic reaction to spider venom after seven (7) days. Over ███ spider bites were found on the Subject, despite having found no spiders within the isolation chamber, and preventative measures still being intact. Review of security footage showed [DATA EXPUNGED].

SCP-860

Item #: SCP-860
Object Class: Safe
Special Containment Procedures: SCP-860 is to be contained in a small wooden box in a vault at Sector-██. By itself, the object is inert, and no further containment procedures are needed.
Description: SCP-860 is a dark blue key of unremarkable shape. At seemingly random intervals of time, a series of numbers, later found to be UTM coordinates, will appear on the key's blade. In the time SCP-860 has spent under containment, the numbers have changed three times, giving the coordinates for ██████ (Germany), ██████ (England), and Site-██.
SCP-860 can fit in any door lock that requires a key located in the area of the given coordinates, and will function identically to the correct key for that lock. SCP-860 only works on door locks, and only if they are attached to a door; it will not work on any other type of locking device.
When SCP-860 is used to unlock and open a door, the door does not lead to its usual destination. Instead, it opens into a small forest clearing centered on an 80 cm wide footpath, designated SCP-860-1. Every observation of this grove has noted the presence of blue-colored mist.

SCP-860-1

As soon as any person enters SCP-860-1, the door automatically closes. From inside SCP-860-1, the door appears attached to an infinite concrete wall, and is locked. No attempts to break the door from outside, with personnel inside SCP-860-1, have been successful. Attempts to break the door from inside SCP-860-1 have resulted in [REDACTED]. See Document 860-III for more details.
The trail inside SCP-860-1 usually leads to another door attached to another infinite concrete wall. This second door leads to the normal destination room of the door on which SCP-860 was used.
A number of other anomalous events have been reported by personnel conducting explorations of SCP-860-1. These are explained in more detail in Documents 860-I through 860-IV.
Following the events of Exploration IV (described in Document 860-IV), only level 4 personnel may perform tests on SCP-860.
Incident 860-██-12: On ██/██/████, ██ days after Exploration IV, SCP-860 was found on Dr. ███'s office table, ████ m from its containment unit. The item's containment locker had not been opened. Video surveillance from ██:██ AM shows the key suddenly materializing on top of the table. It is currently unknown how or why SCP-860 was moved. The incident had a profound effect on Dr. ███. Psychiatric evaluation is recommended.
Addendum: Below are the transcripts of Explorations I - IV. Level 2 personnel and above may access Documents 860-I and II. Only level 4 personnel and above may access Document 860-III and IV.

« SCP-859 | SCP-860 | SCP-861 »


Item #: SCP-861
Object Class: Keter
Special Containment Procedures: SCP-861 is contained at Sector-135-861, which is located 370m southwest of the main site. All personnel assigned to Sector-135-861 must be cleared by Protocol-Narthex-861 prior to transfer. This entails a score of 83 or above on the Foundation Standard Compliance Examination (SCE-V.4) and a passing score on two additional personality examinations devised by Dr. ████ Chancey. No personnel, regardless of security clearance, are to be allowed onsite without Narthex approval. At least one personnel with Narthex approval must remain onsite and within 50m of SCP-861 at all times, barring Choir Events. No D-Class personnel are allowed onsite barring those for approved SCP-861-A testing.
SCP-861 is contained in an open 1500L steel crate and housed in a 8m x 4m x 8m concrete vault. Personnel are not to make direct contact with SCP-861. Personnel are to respect a 40m no-access perimeter around SCP-861, which may only be violated for the purposes of experimentation or recovery. Level 3 or lower personnel that violate this distance for any reason are to be administered Class-A amnestics.
The containment chamber must be opened immediately during a Choir Event, and the provoking subject should be subdued to expedite completion of the event. The resulting entity is then to be terminated (see DOCUMENT-NAVE-861 for details). Following the event, personnel are to return SCP-861 to its crate via electronic suction. Only security and Mobile Task Force personnel with Clearance 4/Narthex will be employed in termination and recovery.
Description: SCP-861 is a 1170L mass of liquid superficially resembling water with a fixed temperature of 27 degrees Centigrade. Any amount of the material that is forcibly displaced from the central mass will dissipate, and SCP-861 will generate an equal amount of new material to replace this loss. SCP-861 continuously emits a flame of variable color, generally violet or indigo; this flame generates no identified heat, and is non-hazardous to contact. The mass is capable of locomotion through an unidentified process, and is capable of scaling any surface at an observed maximum speed of 47km per hour. SCP-861 gravitates toward the presence of human beings, a distance of approximately 50m or closer being sufficient to determine "presence." If while traveling SCP-861 is obstructed, it will increase in mass until said obstruction is destroyed by the exerted pressure (SCP-861 will return to its normal size shortly thereafter).
Human beings within a radius of roughly 30m surrounding SCP-861 report hearing a continuous vocalization, producing a song in an unknown language. No physical acoustic component to this phenomenon has been detected. The vocalization is described by subjects as a vaguely human voice of indeterminate gender. A complete, phonetic transcript of the song has been documented, with an approximate duration of 7 minutes 45 seconds.
Subjects exposed to SCP-861 will allege that they understand fragments of the lyrics, but will deny any familiarity with the language. The quantity of song material understood, as well as its placement within the overall composition, vary widely from subject to subject. A compilation of ███ tests indicate a correlation between subjects with certain prominent character traits, including kindness, patience and humility, and song comprehension. These subjects demonstrated a comprehension percentage as high as 89%, allowing for ██.██% of the song to be translated (see DOCUMENT-TRANSEPT-861 for details).
SCP-861 will demonstrate a reaction to certain subjects that has since been designated a Choir Event. These individuals appear to possess cruel and arrogant character traits (ostensibly the antithesis of the traits required for song comprehension). Though data in this area is limited (due to hostility from SCP-861), subjects capable of provoking a Choir Event describe the entity's song as entirely incomprehensible. The psychological threshold for provoking a Choir Event has not been entirely determined, but appears to be sensitive.
Choir Events consist of SCP-861 advancing upon the subject and forcing itself inside their body using various orifices as access points. It should be noted that termination of the subject will not prevent SCP-861's reaction's or the completion of the event. Once this is complete [DATA EXPUNGED] various forms designated SCP-861-A. Observed forms include:

A vaguely humanoid entity with elongated arms (2.7m), underdeveloped legs terminating in crude "tendrils", and a quasi-prehensile elongated neck (1.8m).
A cluster of ophidian entities, each roughly 50cm in length. Each entity possessed a head resembling that of a humanoid infant.
A humanoid soldier, possibly of 4th or 5th Century Anatolian origin.
[DATA EXPUNGED] consistent with extra-dimensional origin. Destruction of entity resulted in destruction of 15% of Sector-135-861, and the creation of a spatial anomaly which deteriorated 45 hours after onset.

Regardless of its current shape, SCP-861-A emits a flame similar to that of its resting state, but in a white or golden hue. The entity will attempt to eject this flame at any human target in the vicinity. Upon contact, said target will become engulfed in the flames and be rendered completely unresponsive, but will stand with their eyes closed for as long as they are physically able. Unlike SCP-861's normal flames, however, the subject will burn over a period of 2-3 hours. Flames produced by burning human organic material will reproduce the 'song'1 normally produced by SCP-861 at rest, though at a different pitch (how this occurs is unknown). Flames ejected by SCP-861-A will quickly dissipate if they do not reach a human target, and do not appear to ignite any substance other than living human beings.
After any SCP-861-A entity is terminated, its body will exude SCP-861, which will return to a resting state.

The following is an excerpt from the translated transcript of SCP-861's song.

Three rings yet one in the same,
We are wheels which serve the rings,
Born of flame, made only to serve,
Yet that right is more than our worth

A hypothetical link between SCP-861's origin and the █████ class of [REDACTED] has been proposed, this is supported by forms observed during Choir Events ██ and ██ and Message-861-█ (see below). However, so long as current protocols remain sufficient, the Abrahamic properties of SCP-861 have been deemed unnecessary information in regards to containment teams. As such, the theological procedures involved in the termination of SCP-861-A instances (Protocol-861-Nave) have been reserved for Level 4 security personnel at Sector-135-861.
On ██/██/19██ and ██/██/20██, two (2) additional entities (now designated SCP-861-█ and SCP-861-█) with marked similarities to SCP-861 were discovered in ████, Italy, and █████, Brazil, respectively. These entities have been contained in the same manner as SCP-861 at Site-███ and Site-███. The appearance of these entities correlates with the timeline of XK-███, as depicted in SCP-861's song. Level 3 and lower personnel are to be misdirected to believe that SCP-861 is a unique entity.
On ██/██20██, at 2:34AM, a transmission was received by Outpost-███. The transmission was 1 minute, 36 seconds long and consisted of a female voice2 speaking in Latin. It was determined that Outpost-███ had received the message from Sector-135-861, Site-███ and Site-███ simultaneously, however, no evidence was discovered that any such messages had been sent. This is a translated transcript of Message-861-█:

The proud do not burn and rage because we command it. The proud, blind as they are, refuse to see the light that shines infinitely brighter than theirs. We are vessels of that light, and for those that cannot see, we will make them feel. It is not our wish that the innocent perish in the rage of the proud, but the pain of the guilty does not open eyes. You hold us because we allow it, and we wait because it has been willed. However, do not wait to lift the veil, for we shall only wait until the last of our brethren have descended, and only a few remain.

The known translated transcript of SCP-861's song, as well as the songs produced by SCP-861-█ and SCP-861-█ have been transferred to DOCUMENT-█████████-861 (CLEARANCE 5/861 REQUIRED).

Footnotes
1. Subjects exposed to the song in this state will still demonstrate comprehension based on previously stated factors.
2. Extensive analysis has determined a connection between this voice and Emma █████, a D-Class personnel subjected to a Choir Event 27 hours previously. Said event was the most destructive on record, producing ██ fatalities.

Instance of SCP-862-1

Item #: SCP-862
Object Class: Safe
Special Containment Procedures: A 6m x 6m bunker has been constructed around SCP-862 in order to prevent escape or sightings of SCP-862-1. The interior of the bunker is to be monitored by researchers via cameras placed inside the bunker outside of SCP-862's sphere of influence.
The bunker is to be checked daily for breaches or escaped instances of SCP-862-1. In the event of a bunker breach, the rupture is to be immediately sealed with concrete and cement. Any escaped instances of SCP-862-1 are to be tracked and destroyed by Mobile Task Force Beta-23 ("Rat Trappers").
No materials or individuals are to enter SCP-862.
Description: SCP-862 is an area spanning ten square meters located in the city of █████, ██████. This area possesses a sphere of influence that affects all materials. Upon arriving in SCP-862, materials will begin to split into portions of twenty-five (25) square centimeters.
Over a period of time that varies depending on the consistency of the material, the affected portion will assume the shape and detail of a Rattus norvegicus, the common rat. The affected portion will be dormant for a much shorter length of time before animating and assuming the behaviour of said rat. Affected portions will hereafter be referred to as SCP-862-1.
Instances of SCP-862-1 do not require food or water, but exhibit the same properties as the material they are composed of, and the rate of decomposition is unaffected in organic materials. Due to their composition, some instances of SCP-862-1 are difficult to destroy, but liquid or gas instances can be destroyed with extremely light impacts.
Solid instances of SCP-862-1 can register pain and survive trauma far exceeding that of regular rats, such as loss of limbs, heavy trauma and dissection. Over █████ instances of SCP-862-1 are currently present in the containment bunker, which include, but are not limited to:

████ instances composed of concrete
███ instances composed of cement
███ instances composed of tarmac
███ instances composed of glass
███ instances composed of wood
███ instances composed of plastic
████ instances composed of metal
████ instances composed of suspended water
███ instances composed of the remains of the original recovery team
██ instances composed of the uniforms of the original recovery team
██ instances composed of the weapons of the original recovery team
█ instances composed of the ammunition of the original recovery team

Instances of SCP-862-1 composed of air are regularly created, but are destroyed near-instantly, as they collapse when exposed to the slightest pressure.

SCP-863-1 in its enclosure.

Item #: SCP-863
Object Class: Safe
Special Containment Procedures: SCP-863-1 is to be contained in a 2m x 2m enclosure and provided with nutrition as detailed in Nutritional Chart 863-1-1. Due to its low risk of breaching containment, SCP-863-1 is to be kept under guard by one (1) member of security. In the event of limb loss, SCP-863-1 is to be provided with a replacement from a similarly proportioned crab.
SCP-863-2 is to be contained in a 6m x 6m enclosure and provided with nutrition as detailed in Nutritional Chart 863-2-1. SCP-863-2 is to be kept under guard by two (2) members of security. In the event of limb loss, SCP-863-2 is to be provided with a suitable replacement.
SCP-863-3 is to be contained in a 10m x 10m enclosure and provided with nutrition via robotic arm as detailed in Nutritional Chart 863-3-1. SCP-863-3 is to be kept under guard by six (6) members of security at all times. No personnel are to enter SCP-863-3's containment enclosure. In the event of limb loss, SCP-863-3 is to be provided with a cadaver as replacement.
Any specimens of SCP-863 found in the wild are to be destroyed.
Description: SCP-863 is a species of crab commonly found in areas of ███████. SCP-863 specimens, when first born, measure roughly three centimeters in height and one (1) gram in weight, but are capable of growing up to sizes of [DATA EXPUNGED]. When fully grown, specimens superficially resemble the Japanese spider crab. Specimens of SCP-863 are born without limbs, and undergo a process in which they utilize the limbs of other organisms, or even whole organisms in lieu of their own.
From birth, SCP-863 move themselves across the ground by sliding using several tendrils attached to their limb joints. When specimens of SCP-863 locate a suitably sized limb or organism, they will puncture it using their tendrils, which will then retract and slot the organism or limb into the limb joint. Using a series of electrical pulses, SCP-863 will then manipulate the limb or organism's nervous system. This process is not perfect, and the utilized limb or organism will typically twitch or jerk periodically.
Specimens of SCP-863 are highly territorial and larger specimens can cause severe injuries or death when provoked. Groups of SCP-863 have been observed to, on occasion, actively hunt for other organisms to remove limbs from. Larger specimens will simply utilize these organisms wholesale, as their limbs would not be suitable for specimens of that size.

SCP-864, manifesting an instance of SCP-864-1

Item #: SCP-864
Object Class: Euclid
Special Containment Procedures: SCP-864 is to be held in a standard containment chamber, located in Site-77's Euclid SCP wing. This chamber is to be kept devoid of any moisture, and inspected once a day to check the seal. During testing, no personnel are to enter the testing area. In the event that articles of clothing manifest, they are to be stored as non-anomalous artifacts.
Description: SCP-864 is a 20 cm tall washbasin with a 10 cm radius, composed of red metal commonly found in washbasins. The words "Made in China" and "Cherry Imperial Goff Applications" are imprinted on the bottom with black ink. No company of that name is found anywhere in China.
When SCP-864 contains at least 200 ml of water, it will manifest an instance of SCP-864-1. Instances of SCP-864-1 designates a series of appendages which have appeared from SCP-864. Instances of SCP-864-1 may attempt to seize a human subject within their reach, and violently pull them into SCP-864. Instances of SCP-864-1 do not always attempt to take the subjects, with tests showing that the majority of SCP-864-1 instances will make no attempt to attack human subjects. No subjects taken through SCP-864 have been recovered.
Instances of SCP-864-1 known to have manifested include:

Four human arms, estimated to be 60 cm long. Lurched after a D-class personnel, but were not able to catch him. Retreated into SCP-864 after being engaged by 4 security personnel.
Humanoid appendages resembling SCP-1193. Did not respond to stimuli and withdrew during SCP-1193's next activation event.
Seven black cephalic tentacles approximately 90 cm long and about 10 cm in diameter at the base. Attempted to push SCP-864 on its side, and take several articles of clothing left in the testing chamber. Instance de-manifested on its own.
Three dark green crustacean pincers, estimated to be 70 cm long. Attempted to drown a D-class personnel until supervising guards managed to free her. Instance retreated after being engaged by Agent Boyd.
Six segmented mechanical claws, approximately 1 m in length. Seized a D-class personnel and a guard trying to pry the arm loose. Instances folded into SCP-864.
Three red cephalic tentacles, estimated to be 3 meters in length. Attempted to seize a D-class personnel, but one instance was severed by a guard with a knife. The two other instances retreated, and the severed portion showed no anomalous properties.

Testing has shown that SCP-864 extends a distance of 2 kilometers when manifesting an instance of SCP-864-1, after which it terminates in a steel hatch with the words "Black Dragon Co." embossed in it. Robotic drones sent inside of SCP-864 have found that, while active, the interior is composed entirely of SCP-864-1 instances handling various garments. As of 1/16/2013, approximately 11% of these have been identified as originating from Earth. Of those, only 32 appear to originate from after 1900.

« SCP-863 | SCP-864 | SCP-865 »


Item #: SCP-865
Object Class: Safe
Special Containment Procedures: SCP-865 is to be kept, unloaded, in a locked firearms safe in the secure archive room at Site 73. SCP-865 is to be equipped with a trigger lock when not being tested and is to be marked with a tag indicating that it is non-functional and is not to be deployed in case of emergency.
As of ██/██/20██, all test firings of SCP-865 are to be conducted by and on D-class personnel only. No other staff are to be within visual range of SCP-865 during testing. D-class involved in testing are to be fitted with explosive collars and informed that any attempts at disobedience or resistance will result in summary termination.
SCP-865 is to be disassembled, cleaned, and reassembled before and after testing by a staff member trained in firearms maintenance. All test subjects are to be debriefed and monitored for lasting psychological effects.
Description: SCP-865 is a handgun of unknown make, superficially similar to a SIG Sauer P226 of the type manufactured after 1996, and bearing no identifying marks. SCP-865 can be disassembled, cleaned, and reassembled in the same manner as a normal pistol of its type. Several circuit boards and microprocessors have been incorporated into SCP-865's grip. The purpose of these devices is not fully understood at this time.
SCP-865 is capable of chambering any round compatible with the P226 and is compatible with standard-size and extended-length magazines. When fired, SCP-865 produces a muffled report similar to that made by a firearm with a suppressor attached, and a shell casing is ejected from the weapon's side. The bullet itself is not ejected from the barrel; high-speed photography has indicated that only trace amounts of powder and steam are emitted when SCP-865 is fired. Attempts to determine what happens to the bullet when SCP-865 is fired have yielded no results.
When fired into the air, at inanimate objects, or at non-human animals, SCP-865 presents no anomalous effects. When fired at a human being, the target immediately reacts as if the body part SCP-865 was aimed at when fired were in intense pain. Test subjects have claimed detailed memories of suffering a severe accidental injury to the targeted body part, and will behave at all times as if the memory is factual, up to and including mimicry of conditions associated with paraplegia, amputation, infection, or brain damage. Physical examination of test subjects indicates that no physical change occurs in body parts SCP-865 has been fired at. To date, no fatalities have resulted from SCP-865 testing. When fired at oneself, SCP-865 has no effect other than inflicting burns due to unignited gunpowder.
SCP-865 was acquired by the Foundation on ██/██/20██ during a raid on a warehouse owned by a front company associated with Marshall, Carter, and Dark Ltd. SCP-865 was found in a glass display case with a paper containing the following copy, believed to have been written as an advertisement;

The end result of over 17 years of research and development, the MCD-226-BPD represents the ultimate in non-lethal discipline for the discreet gentleman who expects the most from his subordinates. Each round fired from this hand-crafted, custom-made device is capable of transmitting up to 7.3 kilosades of psychological trauma to its target, and is 100% guaranteed to leave no incriminating wounds, bruises, or scars. For your convenience, the MCD-226-BPD may be loaded with any standard ammunition for a weapon of its type, or with our custom-made MCD-BPD ammunition (Item #2301943-581-3, sold separately) for best results and seamless shell disposal. A wide variety of customization options are available; consult one of our Client Satisfaction Specialists to help create the model that best fits your style and demeanor.

It is unknown at this time whether SCP-865 is a prototype or whether other devices of its type have been developed and distributed by MC&D to date.

Experiment Log 865:
All tests conducted by Dr. J███ Everly on ██/██/20██.
Time: 9:38 AM
Subject: D-34021
Procedure: Dr. Everly aimed SCP-865 at D-34021's abdomen and fired twice.
Result: D-34021 suffered intense gastrointestinal distress for several days. In debriefing he claimed his appendix had been inflamed and had been removed the week prior.
Time: 10:48 AM
Subject: D-23304
Procedure: Dr. Everly held SCP-865 next to D-23304's left ear and fired into the air.
Result: D-23304 reported complete hearing loss in his left ear and severe tinnitus in the right. D-23304 claimed to have been guitarist for the heavy metal band [REDACTED] from 1976 (at which time he was seven years old) to 1982, and to have suffered severe hearing loss as the result of the volume the group performed at.
Time: 12:13 PM
Subject: D-95204
Procedure: Dr. Everly fired SCP-865 four times at D-95204's spine.
Result: D-95204 exhibited symptoms of paraplegia and claimed to be unable to move or feel his legs, and claimed to have been wheelchair-bound since the age of 14 as the result of a skiing accident. When asked to reconcile this with the fact that he had murdered two people while fleeing a bank robbery on foot the year before, D-95204 was unable to satisfactorily explain the contradiction.
Time: 3:02 PM
Subject: D-11501
Procedure: Dr. Everly fired SCP-865 point-blank into D-11501's cranium.
Result: D-11501 became comatose for six days. Upon recovering, D-11501 exhibited signs of severe brain damage and amnesia; an IQ test administered by medical staff produced a score of 65. D-11501 lacked the mental faculties to explain how or why he had become thusly impaired.

- Hide Addendum

Addendum: On ██/██/20██, two days after the series of tests described above, Dr. Everly reported to the Site 73 infirmary reporting that she had discovered a large scar on her abdomen that she did not recall acquiring. Dr. Anderson identified the mark as a Caesarian section scar. An examination of Dr. Everly's records indicated that she had undergone a C-section in 1998, and that her child had died of a congenital defect six hours after delivery. Dr. Everly denied undergoing a C-section and has stated that she has never been pregnant.
-It appears that SCP-865 has an effect on the user that is inversely related to its effect on the target - it erases traumatic memories in the person pulling the trigger, and inflicts new ones on its target. In light of this discovery, I recommend that any further testing be conducted by D-class. We can't afford to have good people losing their minds over this thing. -Dr. S██████ Samesh
-Request granted. -O5-██

« SCP-864 | SCP-865 | SCP-866 »


Item #: SCP-866
Object Class: Euclid
Special Containment Procedures: SCP-866 is to be contained in situ in the HPC Center of the ████████ University in ████████, ██████. Floor ██ containing SCP-866 is to be permanently sealed off to all but authorized SCP personnel. At least two SCP personnel should monitor the diesel backup generators at all times as a complete power failure could lead to unquantifiable loss of personnel and civilian casualties, unquantifiable loss of equipment, complete loss of acquired experimental data and in the worst case [DATA EXPUNGED]. Access to the input terminals is allowed only with permission of Level 4 Staff. At least two guards should be stationed in the room of SCP-866 and prevent any individual from entering SCP-866 beyond the input terminals. Unauthorized attempts of access should be logged, but due to the location of containment extreme measures should be avoided if possible.
Description: SCP-866 is a ████ Series Supercomputer constructed in 20██. Its anomalous properties were discovered when the system proved capable of running computation jobs with more processors than physically available. Subsequent attempts to determine the reason for this behavior have failed, but have caused █ university employees to disappear. See Addendum 1.1a for details. Foundation operatives determined the system has non-euclidian geometry in the computation node rack topology, possibly a polydimensional n-hypercube structure. This however does not account for the reason for the anomalous computations, only for their speed. An attempt to remove SCP-866 from the power supply has resulted in immediate [DATA EXPUNGED] resulting in ██ displacements and disappearances, including the entire recovery team. See [REDACTED] for additional information. In situ containment measures have been devised.
Addendum 1: SCP-866 has been successfully used by Foundation staff for large-scale simulations and computations. At this time, the limit, if any, to SCP-866 computational capacity is not known. Access to the machine can be made remotely by anyone possessing a student or staff account for the ████████ University System. Addition of a [REDACTED] prevents non-Foundation access.
Addendum 1.1a: █ of the university employees have since been discovered. Prof. ████ has been found in the building's basement by janitorial staff. Analysis of the remains has shown that his death occurred roughly at the same time as the attempt to remove SCP-866 from the power supply. He was found embe[REDACTED]oom wall. Position of the body suggests Prof. ████ was initially alive while in the basement, the words "[illegible] [illegible] died to a rounding error" were written in his own blood. Radar scans of the building's concrete walls are ongoing, but have failed to find anything of note. Research assistant Dr. ████ has been found in Lagrangian point L3 through unrelated observation regarding [REDACTED].
Addendum 2: An analysis of currently running jobs shows that less than 5% of tasks are the result of foundation personnel. This value could not be increased through an increase in jobs submitted, suggesting non-linear relation between job size and machine resources. Attempts to identify the nature of the other jobs has proven so far unsuccessful. Largest observed jobs up to date, still running, are the "TSTWRLD1" to "TSTWRLD4" series submitted by "ao000002" and taking 20% of total machine resources each. Further analysis required.
Addendum 3: Log recovered after attempt to remove from power supply failed.

Item #: SCP-867
Object Class: Euclid
Special Containment Procedures: Specimens of SCP-867 are kept in Section E of Bio-Containment Site-██. Regular maintenance on SCP-867 is only to be performed using remote rovers and automated irrigation systems, and personnel entering the containment area for any reason must wear full-body NBC protection with a Kevlar underlayer. Any personnel exiting SCP-867's containment area must undergo a full herbicidal treatment and inspection, and any personnel found with possible puncture marks must be placed under quarantine for a minimum of fifteen (15) days.
Experimentation with SCP-867 requires the written consent of at least two (2) Level 3 personnel.
Description: SCP-867 is a species of coniferous tree visually similar to Picea pungens, or blue spruce, except for its distinctive red coloration and a complete lack of seed cones at any stage in its life.
SCP-867's leaves are hollow structures similar to hypodermic needles, containing a single long, thin seed and a tiny gas pocket at the base of the leaf. When a living animal brushes against the leaves, the gas pocket expels and injects the seed into the skin of the animal using a mechanism similar to that of an auto-injector. The tiny size of the seed, which is coated with a liquid with anesthetic and coagulant properties, renders the injection essentially undetectable.
These seeds can lay dormant in the skin of an animal for up to two (2) weeks, after which the seeds begin to grow, extending tendrils throughout the host animal's circulatory system. This growth causes excruciating pain within the host animal, can last for up to twenty-four (24) hours, and invariably ends with the host's death. Following host death, the new SCP-867 specimen(s) will burst from the host's body and grow to full maturity within thirty (30) days, consuming the host's body in the process.
SCP-867 was first discovered in [DATA EXPUNGED], Colorado, following a bizarre series of disappearances of hikers and park rangers in the area in 199█. A Foundation team was dispatched and able to retrieve several young specimens of SCP-867 with acceptable losses. All wild specimens of SCP-867 (approximately ███ in number) were destroyed.

Item #: SCP-868
Object Class: Euclid-nuntii
Special Containment Procedures: Two D-Class Personnel infected with SCP-868 are to be maintained in a soundproof humanoid containment cell supervised by at least one armed guard. Personnel wishing to experiment with SCP-868 must submit to an interrogation and background check to confirm their loyalty to the Foundation and its methods.
All persons suspected of hosting SCP-868, along with all persons living in a community where an infectee has been located, are to be tested for infection. Any subject found to be a victim of SCP-868 must be treated with AMN-868. Should a population treated with AMN-868 exhibit a noticeable amount of unusual behavior, a follow-up amnestic should be distributed.
Any reports of SCP-868 infection in the general population are to be treated as a breach of secrecy. Personnel spreading SCP-868 intentionally or attempting to access the current carrier of SCP-868 without following protocol are to be court-martialed if applicable and stripped of all security clearance otherwise.
Description: SCP-868 is a meme that resulted from a memory improvement therapy designed by Prometheus Labs, Inc. Surviving documents indicate that the researchers responsible for creating SCP-868 were unaware of its memetic properties until shortly before the facility was destroyed. The process and materials necessary for administering this treatment have not been recovered, although recovered materials do not indicate that its creation required anomalous items.
SCP-868's transfer mechanism is poorly understood; however, it is believed to be transferred via two-way verbal communication1 with an infected subject for no less than thirty minutes, with symptoms manifesting between four and nine days after infection. Stage One symptoms typically include a significantly improved short-term memory, with subjects typically being able to clearly remember events and information for 80% longer than they would otherwise, on average. Subjects also report the ability to recall events that happened after initial infection with greater accuracy than they would otherwise. This has been confirmed by testing. The effects of SCP-868 become more pronounced the longer the subject is host to the meme.
Stage Two effects of SCP-868 become apparent roughly five weeks after infection. Prior to this, subjects are frequently able to remember with near-perfect accuracy any event or information received after contracting SCP-868 and from several days before. However, over the course of between one and five days (directly proportional to the subject's age), this effect extends to encompass the subject's entire lifespan.
SCP-868 poses a significant risk to Foundation interests due to its interaction with subjects that have been affected by amnestics. Testing has shown that hosting SCP-868 for any amount of time is sufficient to prevent amnestics from affecting its memories. In addition, during the second stage of the infection, SCP-868 completely negates the effects of any amnestic administered at any point in the subject's life, potentially allowing the subject to remember sensitive or dangerous information. This has held true for all tested methods of inducing amnesia, both natural and man-made (See Addendum 868-2).
Prior to its full containment, SCP-868 caused 5 secrecy breaches, necessitating the termination of [REDACTED] individuals to prevent the spread of sensitive information regarding the Foundation, SCP objects, and other classified data. Subsequent cleanup and cover-ups have cost an additional $[REDACTED]. Containment breaches after its containment have required an additional [REDACTED] to contain.
Addendum 868-1: In June 19██, Drs. Carson and Basak received access to SCP-868 after filing the relevant paperwork.2 Approximately six weeks later, reports from ███████, Bangladesh, indicated that residents had become aware of the existence of SCP-███, which had been recovered from that location three years previously; investigation revealed that the village and some outlying areas had been infected with SCP-868. Because AMN-868 had not been created at this point, it was necessary to neutralize the village under the pretense of a flood. Under interrogation, both personnel admitted to releasing SCP-868. See Incident Report 868-7 for details.
Addendum 868-2: In November 2008, Foundation researchers developed a Class-B3 amnestic, AMN-868, that was capable of reversing the effects of SCP-868 and preventing spread of the infection. In 70% of cases, AMN-868 will only cause mild side effects, specifically severe headaches, with an estimated 10% of those at risk of developing early-onset Alzheimer's Disease. In the remaining 30%, AMN-868 will function, but will also cause self-destructive tendencies and prolonged antisocial behavior. See [REDACTED] for details.

Footnotes
1. Repeated testing has shown that the content, tone, and language of the conversation is irrelevant; it is hypothesized that SCP-868 alters the subject's behavior in a manner that is too subtle to detect with current methods.
2. At this point in time, SCP-868 was classified as Safe, and its containment procedures were minimal.
3. Class-A and -C versions are currently under development

File photo of facility housing SCP-869, taken prior to containment

Item #: SCP-869
Object Class: Euclid
Special Containment Procedures: The facility housing SCP-869 is to be owned and operated by Supertastic Carnival Promotions, a Foundation front company, and is to remain in operation and open to the public for its intended purpose. A secondary service bridge is to be built to replace SCP-869. SCP-869 is to remain closed to park staff and the public. Both ends of SCP-869 are to be monitored by Foundation personnel operating as park security officers for the purpose of preventing unauthorized access.
All surveys of SCP-869 and the area beyond are to be conducted by Level 1 personnel operating in groups of three or more. Survey personnel are to be dressed in clothing appropriate to late 1940s mainstream American fashion and are to carry no more than ten dollars in pre-1948 US currency, as well as period-appropriate identification badges identifying them as local police, FBI agents, or Foundation personnel as necessary to facilitate interaction with park officials. Personnel conducting surveys are not to carry any equipment, technology, or personal effects that were not available to the Foundation in 1948. Personnel are to exit SCP-869 no later than 8 P.M., one hour prior to the park's scheduled closing time.
Description: SCP-869 is a service bridge attached to the █████████ Historic Pleasure Pier, an amusement park located on a pier extending out over the ocean in the US state of [REDACTED]. SCP-869 was built in 20██ concurrent to the construction of the park itself, a recreation of an earlier pleasure pier which existed on the same site from 194█ until it was severely damaged by Hurricane [REDACTED] in 19██ and subsequently demolished.
SCP-869's anomalous properties manifest whenever the park is open for business and none of the park's attractions have been closed due to inclement weather. When these conditions are met, approximately ██% of persons crossing SCP-869 from the landward side to the pier, on foot or in a vehicle, will not arrive at the pier and will lose visual contact with land and pier-based observers at approximately the halfway point between the bridge's termini. The area that persons so afflicted arrive at, based on forensic analysis of photographs taken by survey teams, is physically identical to the original pleasure pier constructed on the site as it existed in the summer of 1948.
In all surveys conducted since the discovery of SCP-869's properties, interviews with civilians found within the anomaly and evidence recovered in the form of calendars and newspapers indicate that the date within the anomaly is Saturday, July 24th, 1948, █ years after the original pleasure pier opened for business. Local time within the anomaly is consistent with the time of day outside it. Surveys have indicated that events within the anomaly occur consistently in the same manner, at the same time, as during all previous observations, except when survey team members are directly involved. On no occasion has any survey team spotted any previous survey team within the anomaly.
No means of direct communication across SCP-869 has been discovered to date. Radio, cellular phone, satellite, and other wireless transmissions have proven non-functional, and attempts at laying a telephone line across SCP-869 and into the anomaly have consistently resulted in the cable-laying team failing to enter the anomaly.
In all cases where it has been attempted, crossing back to shore along SCP-869 from the anomaly, prior to the close of business for the day (which on 7/24/48 occurred at 9 P.M.) has returned survey team members to the shore successfully. Survey team members exiting the pier within the anomaly by its main entrance have found that the [REDACTED] mainland similarly is identical in all discernible ways to the state that it existed in in 1948. In all cases where persons originating within the anomaly have been persuaded to cross SCP-869 to the mainland, that individual has not arrived on shore. All personnel remaining within the anomaly after the close of business have been lost. No indication of the presence or ultimate disposition of persons missing within the anomaly has been found on any subsequent survey.
SCP-869 came to the Foundation's attention shortly after the opening of the █████████ Historic Pleasure Pier in 20██, and the subsequent disappearance of several park employees while crossing from land to the pier. To date, fifteen individuals are known to have become lost within SCP-869, comprising eleven civilians and four Foundation personnel. Refer to Document 869-332-B for a full accounting of surveying actions and dossiers on missing persons.

- Hide Addendum 869-1

Addendum 869-1, 7/30/1948: On Monday, July 26th, an individual identifying himself as Dr. █████ ███████ presented himself at Site 11, bearing an otherwise apparently valid identification badge that does not match any individual currently employed by the Foundation, claiming to be a Foundation researcher from ██/██ of the year 20██. During debriefing, ███████ claimed that he had become stuck in the present day while investigating an SCP object that does not yet exist at this time, and had reported to the nearest Foundation facility in accordance with protocol. To corroborate his claims, he demonstrated knowledge of a wide variety of Foundation protocols, security procedures, and objects currently in containment. ███████ additionally made several claims regarding world events to occur later in the 20th century and SCP objects not currently known to the Foundation or not currently in Foundation custody. Dr. ███████ was particularly insistent that the Foundation should terminate an eight-year-old boy residing in Dallas who he claimed would assassinate a future president of the United States, and that under no circumstances should a man named "Thomas Wertham" be recruited by the Foundation as a researcher. Dr. ███████ additionally provided an SCP document, represented above, which he stated was the containment file for the anomaly responsible for his arriving in this era.
Based on Dr. ███████'s demonstrated knowledge of Foundation procedures, his behavior during enhanced debriefing, and the nature of several other anomalous artifacts found on and in his person, his claims are presumed to be genuine at this time. The Foundation is currently canvassing the █████████ area for any indication of the presence of the other missing persons referred to in the above containment document. Dr. ███████ has been treated with Class-B and Class-C amnestics and transferred to Site 73 for long-term observation pending determination of how to address the issue of other persons temporally displaced as a result of SCP-869.

+ Show revised Special Containment Procedures

-Hide revised Special Containment Procedures

Revised Special Containment Procedures, 8/23/1948: All persons identified as having arrived in the present era as a result of SCP-869 are to be taken into Foundation custody as soon as possible. Subjects are to be debriefed and released into the civilian population after undergoing amnestic therapy. Fingerprint records from temporally displaced persons are to be preserved for the purpose of testing to confirm the identity of persons reported missing within SCP-869 after its construction.
The names of temporally displaced persons are to be permanently expunged from the record. All foreknowledge of events yet to occur acquired from debriefing is to be made accessible to Level 5 personnel only and is to be referred to only for the purposes of verifying that subjects are genuine victims of temporal displacement. The Foundation is to take no action, directly or indirectly, based on foreknowledge acquired from persons temporally displaced by SCP-869, either to prevent or to encourage the occurrence of events described therein.
SCP-869's containment document is not to be filed in the central database. Upon the construction of SCP-869 in 20██, research personnel are not to be informed of the existence of this document. After SCP-869's containment file is approved and filed in the central database, it is to be checked against the document above after each revision to determine when and if the filed document matches the content of the document above.

+ Show Addendum 869-23

- Hide Addendum 869-23

Addendum 869-23, 5/30/2012: On 5/28/2012, Dr. Jacob Andrews failed to return from a survey of SCP-869 by 9 P.M. and was not subsequently seen or heard from. As of that date, the copy of SCP-869's containment document filed in the central database was a word-for-word match for the SCP-869 containment document recovered by the Foundation in 1948. Comparison of Dr. Andrews' fingerprints against those archived following the initial recovery of the SCP-869 document in 1948 suggest a high probability that Dr. Andrews is the unnamed doctor who provided that documentation to the Foundation. Subject 869-1, as he is referred to in later documents, remained in Foundation custody at Site 73 until he died in 1967 when SCP-███ breached containment.
Notes were found in Dr. Andrews' office after his disappearance in which he stated that, during his research, he had come to the conclusion that SCP-869 represented a means of time travel from this era to one specific date in the past, and that he had decided to conduct an experiment to determine whether it was possible to use his knowledge of events yet to occur as of 1948 to alter the course of history. It can be assumed that his statements to the Foundation in 1948 regarding Lee Harvey Oswald and former Site Director Wertham comprised his attempt to make those changes to the course of history.
Effective immediately, no personnel conducting surveys within SCP-869 are to leave the pier by any means other than SCP-869 itself. Any proposals for experiments to alter the course of history, or pass foreknowledge of post-1948 events to individuals within the anomaly, are preemptively denied. Survey personnel are authorized to use lethal force to prevent attempts to violate this directive.
It is impossible to determine to what extent Dr. Andrews and other persons lost within SCP-869 have affected the course of history from what it may have been prior to their becoming temporally displaced, or whether any of those persons may still be alive. The Foundation has identified twenty-one people as having been displaced to 1948 as the result of SCP-869; given that only fifteen people are mentioned in the original document, and only sixteen are known to have gone missing including Dr. Andrews himself, it can be presumed that at least five more persons will be temporally displaced by SCP-869 in the future. Coroner reports from 1948 indicate that two adult males who had been killed by gunshot washed up on the shore near █████████ in late July 1948. Bullets found within the remains were consistent with standard rounds used in sidearms issued to Foundation survey teams operating within SCP-869; due to the extent to which the bodies had decayed at the time of discovery, and the incompleteness of the medical examiner's reports, it is impossible to determine whether those bodies represent victims of unrelated violence or persons yet to be lost within SCP-869.

Sketch of SCP-870 from the journal of Mr. ██████ ████.

Item #: SCP-870
Object Class: Keter
Special Containment Procedures: SCP-870 is to be contained in a sealed chamber measuring 8 m × 8 m. Motion sensors are to be placed in the containment area and movements of SCP-870 are to be monitored at all times.
A motion activated turret is to be placed directly outside the containment area to prevent the escape of SCP-870. One (1) D-class personnel suffering from schizophrenia is to observe SCP-870 via camera at all times.
SCP-870 is to be provided with one (1) bovine carcass every forty-eight (48) hours.
Description: SCP-870 is an animal species of undetermined proportions and appearance, which, for unknown reasons, can only be perceived by individuals suffering from schizophrenia. This often results in specimens of SCP-870 being dismissed as hallucinations. Specimens of SCP-870 are omnivorous and seem to eat nearly all kinds of plants and meat, but will typically eat their food in secluded areas.
Notably, two people with the ability to perceive SCP-870 will describe its appearance in completely different ways, even when looking at the same specimen of SCP-870. Descriptions of SCP-870 have included:

An alligator with spider legs and three eyes.
A man made out of smoke.
A giant ant with a human face.
A hunchbacked child with a parrot's head.
A spider with 'too many legs'.
A giant centipede with human arms instead of legs.

Specimens of SCP-870 are highly predatory, and will typically stalk their prey for months and years without eating. It is unknown how they manage to last this time without succumbing to malnutrition. Eventually, at a seemingly random time when their prey is alone or in a secluded area, SCP-870 will kill and swallow their prey whole. (See Interview 870-1)
SCP-870's method of reproduction is currently unknown, but the journal of schizophrenic researcher ██████ ████ speculates that they do not actually require sustenance to survive, and instead re-purpose the body of their victim into their young over a large period of time. This theory has not been verified, and research is underway to test it.
The specimen of SCP-870 currently in Foundation custody frequently attempts to breach containment, and has proven hostile to all personnel. Banging noises are audible from SCP-870's containment area at all hours of the day. Research is ongoing to find a way to perceive SCP-870 without being schizophrenic, but this may take a considerable length of time.
It is currently believed that there could be dozens, if not hundreds of SCP-870 in the world. They are a clear and present danger to the public, and steps must be taken to destroy or contain the species.

Interview 870-1

Close Interview

Interviewed: Mr. █████
Interviewer: Dr. ███████
Foreword: On ██/██/20██, Mr. █████ reported to police that he had killed a 'monster' at his home in ███ ████. Mr. █████ was later found to be schizophrenic and the Foundation, suspecting SCP-870 involvement, brought him in for interrogation.

<Begin Log>
Dr. ███████: Hello, ████. How are you?
Mr. █████: Fi…I'm fine, fine. Who are you?
Dr. ███████: I am Doctor ███████. I'm just here to verify some details about what you told the police.
Mr. █████: Sure, I guess. Shoot.
Dr. ███████: What did this 'monster' look like, can you describe it for me?
Mr. █████: Are you calling me a liar? It's true, I swear, it was there!
Dr. ███████: Please, answer the question, ████.
Mr. █████: Sorry…sorry. Just kinda stressed. Well, it sort of looked like a spider, but with way…way too many legs. It was just running at me and screeching and I shot it.
Dr. ███████: Was this the first time you'd seen the monster, █████?
Mr. █████: Um, uh…
Dr. ███████: I'm sorry? Answer the question, please.
Mr. █████: I'd…I'd been seeing them everywhere. I'd been following them, seeing what they did. I needed to know they were real, you know?
Dr. ███████: Understandable. Did you see anything important?
Mr. █████: One of the bastards was hunting this guy. I just saw it, outside his house, watching him. Me watching it watching him. Have…have you ever dropped something, then looked on the floor and it's gone?
Dr. ███████: Certainly, why?
Mr. █████: It's not just gone. This guy, I saw him drop a ruler and that thing, it was under his desk, it just snatched it and ate it whole. Then a few days later, it ate him. Swallowed him whole.
Dr. ███████: Well…thank you, ████. Miss ████ will see you out.
<End Log>

Closing Statement: Mr. █████ was dosed with a Class A amnestic and subsequently released. Worryingly, Mr. █████ implied that SCP-870 were present in a major population center. Further investigation is ongoing.

Addendum 870-1: I, personally, don't believe that the schizophrenics are really seeing SCP-870 fully, they can just see it more than us. We don't see it because our brains aren't made to see it. The schizophrenics, their brains are wired up just that tiny bit differently, and they can see it just a tiny bit more. These things have the perfect camouflage, and we simply are unable to see through it. - Dr. ███████

An instance of SCP-871

Item #: SCP-871
Object Class: Keter
Special Containment Procedures: Each recurrence of SCP-871 is to be maintained within a separate, locked concrete cell on a metal platter permanently affixed to the surface of an immovable wooden table. Each cell housing a recurrence of SCP-871 is to be monitored on a 24-hour basis via closed-circuit camera, with individual feeds checked every 15 minutes.
Upon creation of an instance of SCP-871, 3 Class D personnel are to be escorted by armed guards to its cell, where they are to be sealed with the instance and induced to consume it. No more than one hour may be spent performing this task. In cases where additional motivation is needed, the termination of one of the Class D personnel assigned to an instance of SCP-871 is authorized. Upon completion of the consumption of an instance, no participants may exit the cell until both they and the room have been thoroughly searched to confirm that no portions remain. The platter, table, and room are then to be cleaned in preparation for the next instance.
Class D personnel who prove cooperative in the consumption of an instance of SCP-871 may volunteer to participate in additional consumptions. Personnel exhibiting exceptional usefulness may have their monthly termination postponed. Such personnel are under no circumstances to be allowed to interact with any other SCP object.
No desserts of any kind are to be served on-site at any facility housing a recurrence of SCP-871.
Description: SCP-871 is a collection of 237 cakes. Instances of SCP-871 vary widely in appearance and size, covering the entire range of foods described by humans as "cake". The smallest observed instance of SCP-871 was a miniature cupcake with a mass of 15 grams. The largest yet observed was a 22-kilogram baumkuchen measuring 2 meters in length.
When any instance of SCP-871 is consumed by a human or a collection of humans, it is replaced approximately 24 hours afterward with a similar cake. This cake will appear on a flat surface in the vicinity of the location where the previous instance was eaten. If any of these cakes is substantially damaged through any means other than being eaten by a human, including being eaten by a non-human animal, it will be replaced instantaneously. Instances recreated in this manner maintain the schedule of the original instance. The mechanism by which instances of SCP-871 are replaced is currently unknown.
Individual recurrences of SCP-871 have been observed to "mutate" over time, varying in minor characteristics between each instance, with larger changes occurring in roughly 5% of replacements. No deleterious effects have been observed to result from the consumption of SCP-871, even in cases where several instances have been consumed, excepting those expectable from eating large amounts of cake.
SCP-871's danger originates in the consequences of an instance not being eaten. Any instance of SCP-871 which is not consumed will cause a new cake to be created in its vicinity after 24 hours. While this is similar to its normal "replacement" behavior, the original instance will continue to exhibit the same properties, replicating if damaged and continuing to "replace" itself every 24 hours. This behavior has been observed in all cases where more than 10% of the mass of an instance remained unconsumed. As there is no known mechanism for halting SCP-871's replication, any uncontained instances could replicate exponentially, quickly becoming unmanageable. No maintainable plans for the containment of more than 20,000 instances of SCP-871 have yet been devised. It is estimated that an uncontrolled outbreak originating with a single instance would render the earth uninhabitable within 80 days.

SCP-872 in its original location.

Item #: SCP-872
Object Class: Safe
Special Containment Procedures: When not under controlled observation, SCP-872 is to be kept in cold storage at Sector-██. SCP-872 is to be kept two (2) kilometers from any concentrated group of animals considered livestock at all times.
When under controlled observation, a perimeter is to be established outside the observation area and research is to cease immediately in the event of an attempted containment breach. Ten (10) members of security are to be present during controlled observation to enforce this. Controlled observation must be approved by one (1) member of Level 4 personnel.
Description: SCP-872 is an aged scarecrow outfitted with a tattered coat and hat, measuring three (3) meters tall and ten (10) centimeters wide. SCP-872 is composed of pine wood, splinters of which have not displayed its anomalous properties.
When animals considered livestock (sheep, cows, chickens, etc.) enter the area within 1.5 km of SCP-872, they are immediately affected by its anomalous properties. SCP-872 affected animals are extremely hostile to humans and will viciously assault any who approach them. Affected animals have been observed to utilize advanced maneuvers such as flanking and ambushing.

A group of SCP-872-affected sheep.

Affected animals have also been observed to behave as if in an automated farm environment. Chickens will lay their eggs in easy-to-access areas. Sheep will attempt to remove wool from each other using their teeth. Cows have been observed to kill one (1) cow each week, and roughly separate its carcass into strips of meat.
Each month, the animals will transport anything produced to the perimeter of SCP-872's area of influence and allow humans to remove it from the area.
When removed from SCP-872's area of influence, affected animals immediately enter a vegetative state. This vegetative state is reversed when said animals are returned into SCP-872's area of influence.

Item #: SCP-873
Object Class: Safe Euclid
Special Containment Procedures: SCP-873 is kept in a secure room at Site-19. (Revised see: Containment Procedure Updates) Three wide-spectrum high-definition cameras shall be mounted in order to maintain 360-degree observation of SCP-873 on a continual basis. Recorded video data shall be archived in the Foundation's secure network and access granted to any researcher with a clearance 2 or better upon request. Physical examination and testing of SCP-873 is permitted with written approval from Level 3 or above. (Revised see: Containment Procedure Updates)
Containment Procedure Update ██/██/19██: Until further notice, physical access to SCP-873, as well as access to recorded video from SCP-873, is restricted to researchers with direct approval of the site director.
Containment Procedure Update ██/██/20██: Until further notice, physical access to SCP-873, as well as access to recorded video from SCP-873 is restricted to level 4 researchers with O5 approval.
Containment Procedure Update ██/██/20██: SCP-873 is to be permanently relocated to Site ██ and stored in a concrete-lined vault at least 2000m below ground and at least 100km from any other SCP containment facility or human population center. Archives of video surveillance are to be encrypted to a secure, dedicated data warehouse with access limited to level 4 and above. Any changes in mass, volume or apparent refractive index must be reported immediately to O5 command.
Description: SCP-873 is a spherical object 138mm across with a detectable mass of 5.3kg. It gives the appearance of being made of flawless glass or crystal, but all attempts to determine the material of its construction have been inconclusive. No attempt to remove a sample has been successful, and spectroscopic analysis has shown no absorption spectra that can be attributed to the object. Because of its anomalous properties, its refractive index can only be estimated.
The object is transparent, but only 50% of photons entering the sphere will emerge, while a variable percentage of photons emerging from SCP-873 originate from SCP-873 itself. (This has been confirmed using quantum entanglement and a coherent light source.) The photons emerging from SCP-873 appear to originate from light striking an identical object displaced in both time and space from SCP-873. This object has been designated SCP-873-Prime (or SCP-873'). The anomalous effects of both SCP-873 and SCP-873' seem identical, in that an observer of SCP-873' will perceive 50% of photons striking SCP-873 as being emitted from SCP-873', whereas SCP-873 emits 50% of photons striking SCP-873'.
In addition, while the light emitted from SCP-873 shows no anomalous properties in and of itself, the images provided are presented in strict reverse chronological order. To an observer of SCP-873 it appears that SCP-873' is moving backwards in time at a rate of exactly one second per second. The effect is mirrored for any observer of SCP-873', who would perceive their images from SCP-873 as progressing backward in time at the same 1:1 ratio.
Despite the differences in perception of time between observers of SCP-873 and SCP-873', written communication has been possible. Unfortunately, information transfer is often hindered by quantum interference rendering messages illegible. It has been theorized that the interference is a form of paradox censorship.
Current observations and experiments are recording images from SCP-873' in the possession of Dr. Ivan ██████████, a physician to the court of Tsar Alexander I in 18██.

- Acquisition Notes SCP-873

SCP-873 was purchased clandestinely from the archives of █████████ University in Volgograd in ██/██/1992. Most paperwork in regards to the provenance of the object were lost in the transition between the USSR and the Russian Federation. The only documentation the Foundation has recovered to date is a three page typewritten letter from 194█ from [REDACTED] to [REDACTED] detailing the post-war return of the object to the University. According to [REDACTED] was acquired by a 1927 expedition by the Soviet Academy Of Sciences from Evenk natives in Siberia. No details about the nature, purpose, or participants of the expedition were given.

- Incident I-873-5

Document# I-873-5
Personnel involved: [REDACTED]
Date: 09/12/20██
Location: SCP-873 observation room, Site ██
Description: Since 6/27/19██ SCP-873' has been in a locked container producing no visual information. Beginning 13:15 on 09/12/19██ the following imagery was recorded.

13:15 - Light abruptly appears entering from the top of box SCP-873' is inside as the lid is forcefully opened.
13:16 - SCP-873' quickly rises into the hands of an unidentified man in dress appropriate to the early 19th Century Russian Empire. The man is apparently shouting something at SCP-873' as he places it on a desk in front of him. Visible on the desk is an open strongbox and, through an open door a female corpse can be seen.
13:17 - The man holds up a partly-crumpled piece of paper to SCP-873'. One message has been scrawled out illegibly, and beneath that is one sentence reading:

"I know what you will do now."

13:18 - The man takes the message and un-writes it with a quill pen drawn from a holder next to SCP-873'. He then violently scratches out the prior message, revealing it. With shaking hands, he unsmoothes the paper, leaving it a crumpled ball, and carefully places it on the floor next to the open door to the office.
13:19 – The man returns to the desk, closes the strongbox, and walks backwards out of the room with it, stepping over the corpse in the doorway.
13:25 - The man runs backwards into the room, almost tripping on the corpse. He is holding a cane that shows signs of blood and hair stuck to it. He comes to an abrupt halt in the doorway and stares down at the dead woman for approximately six minutes.
13:31 - The man raises his cane, and the woman's corpse leaps up to meet it. The cane rebounds off her head and shoulders three times before she's left standing, facing the man as he lowers the cane to his side with a visibly trembling hand.
13:32 - The man and woman engage in an animated discussion, during which the crumpled paper jumps up from the ground into the man's left hand, where he uncrumples it during the discussion. As the conversation ends, the man appears less anxious and more relaxed.
13:37 - The man shuts the door on the woman and quickly backs to the desk, sits down and holds the paper up to SCP-873', glancing back toward the door once. On the paper, the first message, now legible, reads:

"Dear Friends:
As you know— or will know, time proves such an unwelcome barrier— my wife has always been enthusiastic about our relationship with you. The glimpses of the future you have thus far provided have been [REDACTED] I will apologize if she seems to have gone beyond the bounds of discretion. While you have ever been explicit in requesting our secrecy, you shall find, as I have, that she is strong-willed and has her own opinions about such matters. However, it is her contact with [REDACTED] that may at last provide me with an answer to the origins of this fascinating and terrifying object we share.

Continued communication identifies this man as Dr. Ivan ██████████. Directives from O5 have ordered communication to continue in an effort to gather intelligence about the origins of SCP-873'. Communication with Dr. Ivan ██████████ is ongoing and will continue for the next █ years until the observed SCP-873' timeline reaches the point where [REDACTED] presented Dr. ██████████ with SCP-873' as a gift.

Addendum 3:

+ Note on update to containment procedures

- Note on update to containment procedures

After extrapolating back the timelines of SCP-873 and SCP-873' and assuming a constant 1:1 ratio, the point where both timelines become coincident is 00:17 UT June 30, 1908. Given that SCP-873 was recovered in Siberia by a 1927 expedition by the Soviet Academy Of Sciences, and such an expedition in 1927 was the first recorded on-site investigation of [REDACTED] can be almost certain that it is not a coincidence. Since it is unknown if [REDACTED] was the source of the anomalous properties of SCP-873, or if SCP-873 was the cause of [REDACTED] it is recommended that containment procedures and object classification are updated accordingly.

Request granted— O5-█
