Item #: SCP-339
Object Class: Keter
Special Containment Procedures: SCP-339 is contained at Site-49. The room containing SCP-339 is 5 m X 5 m X 5 m and sound-proofed. SCP-339 is sealed in a sound-proofed container on a 1.5 m pedestal in the center of the room. The room is only accessible through an outer sound-proofed airlock.
All personnel entering SCP-339's holding room for maintenance must maintain absolute silence and wear noise-reducing foam-lined boots, available in the airlock. Regular maintenance of SCP-339 is to occur on the 15th of every month, and consists of replacing the degraded sound-proofed container with a new one.
No one is to enter SCP-339's holding room for any reason other than maintenance.
Description: SCP-339 is a group of tendrils extending off a central mass. It is approximately 50 cm from tip-to-tip, although this is variable. It appears to be made out of weathered copper, but shows a much higher level of durability and independent mobility. The individual tendrils constantly move as though underwater, continually grinding on the sides of any containment, silently pulverizing it at a gradual but constant rate. Because of this, the sound-proofed box it is currently contained in must be replaced at regular intervals.
Any noise above 14 decibels will cause SCP-339 to become hostile. During this noise and for a length of time equal to 5 times the duration of the noise, any movement within visual range will result in the immediate reaction of SCP-339. SCP-339 will expand by extruding tendrils at an extremely high rate, ensnaring any moving organisms or objects, designated "targets." Once the movement has been restricted, SCP-339's tendrils begin to vibrate at rapidly increasing oscillations until the target is rendered incapable of movement. Note that once a target is ensnared, SCP-339 appears to be able to determine when the target truly becomes incapable of movement rather than merely when it stops moving.
SCP-339 will then return to its base shape and size. At this point, secretions of blood and a slurry of bone and muscle tissue from the central mass are to be expected. All movements of SCP-339 are completely silent, even at very high oscillations that should produce noise.
History: SCP-339 was recovered in Iran in 1953, during Operation Ajax on the part of the Iranian military. It was found in one of Prime Minister Mohammed Mossadeq's private collections. After the deaths of the Iranian soldiers sent to secure this collection, the Foundation was alerted and took control. SCP-339 was found in a velvet-draped room on a pedestal.
A quote from the Persian poet Saadi was engraved onto the pedestal in Persian: "Nothing is so good for an ignorant man as silence; and if he was sensible of this he would not be ignorant."

Item #: SCP-341
Object Class: Safe
Special Containment Procedures: The exhibition hall of Reliquary Research and Containment Site-76 has SCP-341 on display for all Research and Command personnel to view.
Description: A collection of eleven brass and iron orreries found in a large storage room of a basement at Oxford comprise SCP-341. Each orrery is a rough scale model of a different extra-solar star system, complete with planets, moons and one or more suns in the center. A unique clockwork mechanism under each orrery allows the brass models of planets and moons to spin on axis and rotate around each model of its parent star(s). Testing dates each machine to be between 150-200 years old, but without any specific markings, researchers have been unable to determine who created them.

A design found with the collection that either was never constructed or is simply missing.

The orrery collection of SCP-341 was set to be released into the hands of a local museum until an SCP astronomer with a piqued interest in the discovery recognized one of the orreries (SCP-341E) as star system Upsilon Andromedae-A (unique for being a "Solar Twin" of our own sun with "Hot Jupiter" like planets). Further research has matched five of the eleven orreries with possible known extra-solar systems. Including:

Beta Canum Venaticorum
37 Geminorum
HD 98618
18 Scorpii

One orrery, known as "the wheel of doom" amongst researchers, depicts a similar solar system very reminiscent of our own Sol's. Though the planets and Sun themselves are neither near to scale nor spaced proportionately, the presence of seven major planets of our own system is fairly obvious, including Saturn and its rings and the tilted side of Uranus. There are also 5 minor planets included beyond the orbit of Neptune. The orrery is missing a model of Earth and instead has a free Moon roaming through a debris field similar to the asteroid belt present between Mars and Jupiter.

Item #: SCP-365
Object Class: Euclid
Special Containment Procedures: SCP-365 is to be stored in a storage locker at Storage Site-23. SCP-365 must be kept away from any body of water except for testing purposes. SCP-365 is to be kept in its testing pool at all times. The door to the pool is to be locked and guarded by one security guard (see Addendum 365-02). Experiment requests must be approved by a Level-3 researcher.
Description: SCP-365 is a green pool noodle made of polyethylene foam. By itself, it displays no unusual properties and is physically identical to a typical noodle of similar size. SCP-365's unusual properties manifest only when it is placed in a body of water. When a subject completely submerges in said body of water, they become unable to get out.
Subjects report a sense of dread, and describe themselves in an infinite sea, swimming endlessly in a direction and finding only more water (see Audio Log 365-03). It is important to note that to outside observers, the subject simply seems to be flailing in place.
The only way to remove a submerged person from the water is to remove SCP-365, negating its effects. All other methods of rescue have failed; cables and ropes have exhibited an unnatural resistance and snapped, drainage systems have failed, and human intervention has led to [DATA EXPUNGED].
Addendum 365-01: SCP-365 was discovered in ███████, ██████, on ██/██/19██. Retrieval personnel found it at the ██████████ Public Pool along with the bodies of ██ civilians. Because SCP-365's properties were unknown at the time, █ agents lost their lives. SCP-365 was eventually found and removed from the pool, and carbon monoxide from an improperly maintained water heater was used as a cover story.
Addendum 365-02: On ██/██/20██, Researcher █████ discovered that Hallway 19 of Storage-Site 23 was flooded. █████ noticed water leaking from SCP-365's storage locker at a rate of 5 L/min. She quickly notified Doctor █████, who opened the locker to find SCP-365 producing water from its holes. SCP-365 was subsequently moved to its testing pool, whereupon the flow of water stopped. SCP-365's containment procedures have been changed accordingly.

Item #: SCP-368
Object Class: Safe
Special Containment Procedures: SCP-368 has not yet warranted any need for containment. Though it has the movement patterns and behavior common to a normal bird, neither it nor any of its copies (see Addendum) have shown any desire to migrate from the offices in which they are stored.
Description: SCP-368 is an animated origami crane folded from ornate, heavy-stock paper. Left to its own devices, it will perch, preen, fly from platform to platform, groom, and occasionally construct a makeshift nest out of nearby office supplies. It responds to human touch affectionately, much as a domesticated bird would. The item's demeanor is, on the whole, friendly, and it has been observed to perch on the shoulders of various SCP personnel. Though the item needs no source of nourishment, it appears to "sleep" at night in that it places its head under its wing. Studying the physical properties of SCP-368 has proven difficult: the item seems to interpret attempts to capture or contain it as a game and has displayed considerable agility and resourcefulness in evading even the most focused attempts at containment. How SCP-368 stays airborne and maintains its stability while airborne are still not known.
History: SCP-368 was discovered in an office building in ████████, Japan, in 19██. ███ ████ (now employed as [14-1158]), a former employee at the aforementioned building, found the item in a closet full of office supplies. Upon discovery of SCP-368, 14-1158 managed to gain its trust in order to move it to a more secure location. Psychological evaluations of 14-1158 indicated her to be of sufficient mental stability and acuity to warrant a position within the SCP organization.
Cross-SCP Warnings: It is recommended that SCP-368 be isolated from SCP-529 and SCP-530, as contact will almost certainly alarm all three SCP's.
Addendum 0-22: On ██/██/20██, while housed in Research Sector 15, SCP-368 began displaying unusual behavior. Instead of its normal routine of human interaction, grooming, and play, it began hovering over a photocopier (serial number ██████████), "flattening" itself whenever SCP personnel approached. Dr. █████ ██████ ([19-1425]) placed SCP-368 into the photocopier and made a copy, upon which another sheet of paper of identical pattern but different hue emerged from the copier and promptly folded itself a shape mimicking that of the original. SCP-368 and the new specimen (referred to as SCP-368α) resumed usual behavior. Since then SCP-368 has displayed similar behavior at intervals varying between two and four years, while the copies have shown no such behavior. Though initially Overseer O-█ disallowed any employee from aiding in the reproduction of SCP-368, and Dr. █████ ██████ was reprimanded for his action, remarkably high employee morale at Research Sector 15 led to the introduction of the progeny of SCP-368 at further SCP facilities.

Item #: SCP-369
Object Class: Euclid
Special Containment Procedures: SCP-369 is to be monitored by time-lapse camera feed, to be reviewed for anomalous behavior every twenty four hours. Motion sensitive perimeter alert devices should be placed at the borders of SCP-369 each time it relocates, with at least three Level 1 personnel nearby to behave as a semi-active construction crew when under observation. Personnel are to avoid directly observing SCP-369 when no other potential observers are present, though indirect viewing through video or even mirrors has no effect, allowing SCP-369 to continue as normal.
Under no circumstances should actual construction work be attempted on SCP-369, nor should the equipment around it be used. Upon loss of contact with SCP-369 when its task is finished, site monitoring should be repackaged and ready for transit to a new location. Once 24 hours have passed, all roads within 75 km (46.6 miles) should be examined for construction work not matching work schedules of the regional government. Only paved roads are to be examined, beginning with sections of road with comparatively lower usage.
Description: SCP-369 is a migratory road construction zone which repairs stretches of road left untended by repair crews. It generates nonfunctional look-alikes of several essential road construction vehicles, of note being a small steam-roller and an earth mover, the latter being anything from a bobcat to a backhoe. The traffic cones present at the border of the effect are actual traffic cones, lacking any serial number or manufacturer's mark, and always appear to have been in use for at least a few years. If removed from the site, the cones vanish when unobserved. The machines cannot be used or maintained, and testing has shown it unwise to try.
The repair process takes up to four days, as the road undergoes a semi-organic healing process when not directly observed, resulting in mundane yet professional quality patches made to the pavement. No special properties have been observed in the stretches of road already visited by SCP-369: they resume weathering and wearing down like any normal road as soon as SCP-369 is not present.
Tests with construction on and attempted disruption of SCP-369 have resulted every time with the subject being covered in liquid tar and [DATA EXPUNGED] until the bones and inorganic hard materials were ejected onto the roadside. Effect seems limited to paved United States roadways, and no line-repainting is done.
Addendum: Attempts by Level 2 research staff to redirect SCP-369 to specific roadwork locations has been so far unsuccessful, though some progress has been made in trying to identify potential targets in advance.

Item #: SCP-377
Object Class: Safe
Special Containment Procedures: SCP-377 is kept in the Personnel break room, third cabinet to the left of the refrigerator. Any personnel desiring a cookie from SCP-377 may take one (1), and only one cookie, every 48 hours, to ensure that all personnel get a share. Personnel read their fortunes at their own risk.
Description: SCP-377 is a box of La Choy brand fortune cookies. The box was full when it was recovered from [DATA EXPUNGED] and has since restocked itself regularly every 12 hours.
The cookies within the box are individually wrapped (for freshness, according to the box) and are, according to all tests, totally ordinary. Each cookie contains one (1) 18mm by 58mm piece of paper, on which a "fortune" is written in blue ink. All of these properties are consistent with a box of cookies from this brand.
However, the "fortunes" contained within each cookie are not consistent with those provided by the standard product. "Fortunes" appear to be specific to the individual opening the cookie and have thus far shown to be 100% accurate, ranging from vague indications of coming success to specific predictions regarding personnel's personal lives. The "fortunes" are not, however, always positive.
It is unknown whether the fortune cookies actively predict future events, or in fact cause future events to occur.

Document #377-01: The following is a partial log of some of the more notable "fortunes" given out by SCP-377.
"Fortune" text: "It's a boy!"

Corresponding result: Subject's wife's water broke less than an hour later. The child was male.

"Fortune" text: "The weather is really just not your friend today."

Corresponding result: Subject was struck by lightning later on the same day. Subject made a full recovery.

"Fortune" text: "Keep playing; you're going to win soon."

Corresponding result: Subject was a regular player in the state lottery, buying two lottery tickets a week. Four weeks after receiving this "fortune," subject won over 100 million U.S. dollars.

"Fortune" text: "Life is laughter; enjoy it while you can."

Corresponding result: Subject suffered an Aneurysm leading to massive hemorrhaging and sudden death. This occurred while subject was laughing.

"Fortune" text: "Duck."

Corresponding result: [DATA EXPUNGED]

Addendum: Following SCP-377's prediction of the deaths of several personnel, a request was submitted to upgrade SCP-377's class to Keter. These were denied, citing a lack of evidence that SCP-377 had any actual connection to the causes of the deaths.
Addendum: Dr. ██████ received a fortune reading, "You don't have long to live." Dr. ██████ was then startled by a guard who entered the break room, and began to choke on the cookie. The guard did not know the Heimlich maneuver and Dr. ██████ tragically suffocated and died. This has been regarded as an accident and coincidence.
Note from Agent ████: I strongly discourage the recreational use of SCP-377. Knowing the future sucks all the fun out of life, believe me, I know.

Item #: SCP-379
Object Class: Safe
Special Containment Procedures: SCP-379 is to be kept in vault-████ at Sector ████-█ when not in use. When being transported it should be carried in a locked and padded container, such as a padded briefcase, as the bottle is fragile. As our supply is limited, all testing and experimentation must be authorized by Dr. ███████ beforehand.
Description: SCP-379 is a translucent, pale, silver liquid contained in a small crystal bottle. The bottle is topped with an atomizer cap which delivers approximately one-half (.5) ml of the clear substance inside the bottle.
The bottle itself has no noted properties of any particular interest. However, the liquid inside (while scentless and ineffective to normal human beings) has the strange effect of inducing a state not unlike human infatuation upon electronic and mechanical devices. When applied to a person or some object, any machines or electronics in the vicinity (aside from those wearing SCP-379) will begin running in an overheated state, unable to process as many commands and consuming more energy.
For cybernetic systems or computers deemed 'sentient', the target seems to exhibit more humanistic qualities of typical 'infatuation' including:

A preference to be around or in contact with the wearer of SCP-379.
More willingness to cooperate with anyone in the room while the wearer of SCP-379 is present.
Slower response times in machines.
A slightly higher chance of minor glitches and malfunctions.

It has been suggested to expose aggressive SCPs such as SCP-███ to SCP-379 to see if the pheromone can reduce their aggressiveness, perhaps allowing us to ask more questions about their function. It has also been suggested to try SCP-379 on SCPs that are not mechanical and do not exist in our 3D, real-world state (as is the case of SCP-732) to see if the pheromone affects them; deemed unlikely.
There is no known reason as to how the sporting of SCP-379 affects most machines; SCP-379 does not release any sort of scent or detectable pheromone into the air. It has been suggested that SCP-379 has an electromagnetic frequency of some sort, but tests have proven this theory inconclusive. Further tests are to be limited until chemical composition is established to determine if SCP-379 can be artificially replicated.
Addendum 379-A: Experiments with SCP-379 and SCP-915 show that purely mechanical devices of sufficient complexity could be affected by SCP-379. SCP-915's intake of air increased threefold, but this was not accompanied by a detectable increase in computation speed. Requests have been made to test if the internal shifts of SCP-915 increase in response to SCP-379. Due to lack of quantities of SCP-379, continued experiments with SCP-915 are denied.

Item #: SCP-380
Object Class: Safe
Special Containment Procedures: This object should be kept connected to a small computer in health lab H██, in the off position. The object may be disconnected and moved to any computer that is capable of an internet connection, but by the request of Dr. ████████, should never be attached to a computer with internet access.
Description: SCP-380 is a small, blue box with an appearance not unlike an internet router. It has a single antenna, a few lights, a power switch and a single T3-line female connector. Although there is no plug for an outside source of electricity, SCP-380 will work when it is connected to a network-capable computer and the 'power' switch in the on position.
The device seems to be compatible with any computer it is connected to (hereafter referred to as SCP-380-1), and will open a large network connection; low-performance computers are commonly unable to maintain said connection. Instead of wireless connections to other networked computers, however, the network is made up of biological entities within a 15-meter radius. Entities compatible with this network include but are not limited to humans, animals, and plants.
As networked entities enter and leave the radius of connection, network connections are respectively formed and severed. Test subjects (and it is assumed all biological entities) are not aware that they are connected to a network. The only effect that is immediately obvious is the ability of SCP-380-1 to access biological components.
When a biological component is accessed, it contains a single text document readable by whichever operating system is utilized by SCP-380-1. Each text document contains variables such as 'heart rate', 'stress', and 'blood glucose level' - among various other physiological parameters, demonstrating accuracy surpassing that of modern technology.
Experiment 380-01: Attempts to edit any of the text documents kept in organic 'files' has responded with a message reading "ERROR 271: Data out of range.", and the loss of any changes made to the file.
Experiment 380-02: Normal health monitoring devices have shown the numbers reflected from organic 'files' to be accurate and therefore should be accepted as true. Requests to research SCP-380 as a potential health monitoring device are pending.

The first leaf of SCP-381

Item #: SCP-381
Object Class: Safe
Special Containment Procedures: SCP-381 is to be kept in a 23 x 31 cm document envelope in Storage Unit-05. Further containment procedure is not necessary under non-testing conditions. Non-Roman Catholic Christian (i.e., any Protestant denomination) research staff are not permitted to perform tests on SCP-381 due of the risk of combustion; other Abrahamic or non-religious personnel are not at risk.
Description: SCP-381 comprises 7 unbound pages of yellowing paper sheet music. Chemical analysis has confirmed that the ink on the paper is made of a mix of a solution of tannic acids with ferrous sulphate and gum, consistent with a recipe for ink contemporary with the paper's estimated year of production (15██ CE).
Each page contains 8 bars of a contrapuntal, polyphonic, Baroque choral composition with overlapping harmonies written for bass, baritone, tenor, and soprano/castrati vocal parts. None of the script is legible with the exception of the rubricated capitals interspersed throughout the piece.
Anyone who touches SCP-381 abruptly begins to sing from the beginning of the composition in a range suited to their age and gender but with professional-level competence. By measure █, other voices will have joined: such voices emerge from the air around the SCP, and sound like a choir made up of between ██ and ███ members, singing lyrics in Latin that translate to [DATA EXPUNGED]. When the singers reach measure ██, all non-Roman Catholic Christians in the area (including the singer, if applicable) will spontaneously burst into flame that extinguishes only upon cessation of life function and cannot be extinguished by any available means. The flame is otherwise normal, emitting heat and light as would be expected.
SCP-381 was recovered by Agent ██████ in █████, Spain on ██-██-██. It was found in an unopened envelope sealed with the arms of Philip II of Spain, along with the preserved skeleton of a messenger (further examination of the skeleton revealed probable cause of death as [DATA EXPUNGED]). Along with SCP-381, the envelope contained a written note to “HRM Elizabeth I on the event of her Coronation,” expressing Philip's congratulations and wishes for a prosperous rule, and the contents of the envelope are noted as “a composition to ryvle the beauty of even Your Majesty.” The missive is dated 28 December, 1558.
Addendum-381-1: Research in the Vatican Archives by Dr. ███████ with the help of Cardinal ████████ has revealed a work commissioned by Pope Paul IV matching the description of SCP-381, though no mention is made of any unusual combustive properties. The piece was commissioned from Italian composer ███████ █████████, who notably vanished after he [DATA EXPUNGED].
Although this information is largely irrelevant to the status of the SCP today, it is of great historical interest when framed in the politics of the Protestant reformation and Catholic counter-reformation. General Bowe is obviously not the first to try to weaponize SCPs. – Dr. ███████

Item #: SCP-385
Object Class: Safe
Special Containment Procedures: SCP-385 is locked within a standard fireproof container at Storage Site-23. Experimentation with SCP-385 requires written approval from any Level 4 researcher. After the incident outlined in Report 385-c all further testing must take place in a facility located within five degrees of either of the Earth's poles.
Description: SCP-385 is a waist-mounted harness crafted from heavily antiqued leather and brass. A curled electrical cord connects a hand-held push button switch to the mechanism mounted on the front of the harness, which itself contains a superfluous set of interlocking gears and colored LED light bulbs. The harness has sustained significant impact damage. A damaged engraving on the front of the mechanism reads "Special Edition! 3 of [ILLEGIBLE]" and "[ILLEGIBLE] by The Factory."
Also retrieved with SCP-385 were a cardboard storage box and instruction manual. Both the box and manual feature a retro art style reminiscent of 1950's science fiction pulp illustrations. The manual describes the harness as a "Personal Anti-Gravity Field Generator" and contains simple illustrations in the "proper" use of the device.
When operated according to instructions, SCP-385 does create an energy field that counteracts the influence of outside gravitational forces upon the device and an individual wearing or holding it, as well as neutralizing their inertia. Measurements of velocity and direction with high-speed video cameras tentatively indicate that inertia is neutralized relative to the Sun as the inertial frame of reference. Research to duplicate this effect is ongoing, but the mechanical components of the device appear to be non-functional. The harness will still produce the anti-gravity effect even when all mechanical components beyond the activation switch are removed.
Addendum: Except under strictly controlled conditions, use of this device is invariably fatal due to the speed of the Earth's rotation and revolution around the Sun. An individual removed from both the Earth's gravitational pull and momentum would either be flung into space or experience a fatal collision with an object blocking their trajectory, which will at least result in the device's deactivation to allow for retrieval.
SCP-385 was recovered from the room of a 13-year-old boy in █████, ██, shortly after what appears to be its first activation. It is unknown how many other SCP-385 mechanisms may still be at large, or how large the "production run" was. Interviewing the deceased boy's parents traced SCP-385 to a downtown antique toy store where the device was purchased as a novelty. The store was found to be abandoned, and had not been occupied for some time. Downtown residents do not remember the shop ever being open.

Item #: SCP-388
Object Class: Euclid
Special Containment Procedures: SCP-388 is to be kept in a locked safe in a room guarded by at least two (2) armed guards instructed to refuse access to any unauthorized personnel; use of lethal force is permitted to this end.
Unless undergoing experimentation, SCP-388 is to remain outside the influence of any other SCPs demonstrating properties capable of modifying physical laws or drawing energy from unknown sources.
Description: SCP-388 consists of a foldable nylon frisbee of the type commonly given away as promotional material, in this case bearing the logo of the Banana Boat Suntan Lotion corporation. SCP-388 appears to be immune to damage; during testing, it has been able to withstand high caliber rifle shots, immersion in high acidity baths, and sustained temperatures of 3500 °C. In all cases, it would spring back, unharmed, to its original shape. X-ray crystallography reveals the molecular structure of SCP-388 to be completely normal nylon supported by a ring of metal appearing to be aluminum.
SCP-388 was discovered after witnesses in a local news report in the town of █ █████, ███ claimed a power line was downed by a UFO. Agents embedded with maintenance crews investigated, and found the concrete pole was sliced cleanly with no tool marks, prompting full investigation status. Aerial records obtained from NORAD and ███████ revealed no abnormalities such as [DATA EXPUNGED] typically associated with [DATA EXPUNGED]. The investigation was nearly terminated until agents posing as reporters interviewed the ████ family, originally questioned in the news report, and their child ████ mentioned the entire incident as being caused by a frisbee. Initially skeptical, efforts were nonetheless taken to verify this claim, with initial confirmation made on ██/██/██. A full week of helicopter searches of the neighboring city of █████ and numerous retrievals of unremarkable frisbees from rooftops eventually yielded results. Unfortunately, Agent ███ was fatally dismembered by SCP-388 when Agent ████ threw the object down from the roof. Under the guise of replacing a septic tank SCP-388 was dug up from its resting place 5.5 m below the yard, and carefully brought in for containment.
SCP-388 when thrown by a human appears to travel as a normal frisbee would for a distance of approximately 3 m. After this distance, SCP-388 immediately begins glowing bright white, and accelerates until its velocity reaches approximately ███ m/s. SCP-388 will proceed to cleanly slice through all intervening matter, regardless of consistency, until eventually coming to rest. Current theory holds that it loses speed due to friction between its top and bottom surfaces and the weight of material pressing down on it as it passes through objects. SCP-388 does not differentiate between matter and test subjects assigned to catch it.
Addendum: Inquiries into the potential use of SCP-388 as a weapon have been declined by ████ in light of the obvious difficulty of retrieving it after its first throw.

Item #: SCP-389
Object Class: Safe
Special Containment Procedures SCP-389 requires no exceptional containment. When not in use, it is stored on a shelf in the office of Dr. ███████ at Site ██ due to the site's proximity to the sea.
Description: SCP-389 is a green glass bottle, approximately 45 cm in length. There are no markings or other distinguishing features on it.
SCP-389 appears highly resistant to damage, having been dropped or knocked from its shelf multiple times with no fractures, chips, or other damage. Analysis of the material it is made of show it to be identical to normal glass.
Object was discovered on [DATA EXPUNGED] in the possession of a 15-year-old girl named █████████████. She shared the history of the object as she knew it, which was: She discovered it on the beach approximately six years ago. On a whim, she composed a note, placed it inside SCP-389, and threw the object into the sea. Several days later she returned, to find SCP-389 washed up on shore, with a reply enclosed. She had been corresponding with another person this way ever since this discovery.
Upon testing, it was discovered that this phenomenon appears to work with any note, and after being cast into the sea, would return at high tide the following day, containing a letter. A test consisting of sending the bottle without a note ended with the discovery of the still-empty bottle the next day.
Messages received are written in English, and appear to have been produced with a mechanical typewriter. The composer of the letters seems loath to reveal any personal details beyond her name (Gedril) and sex. Any questions about or requests for her geographic location are ignored.
"Gedril" will describe the area surrounding her home, wildlife, food, culture, customs, and apparently anything not relating specifically to herself readily and in detail when possible, though her knowledge of many things is limited. Many of the things described are unusual; among them are trees that uproot themselves and migrate, and the life cycle of insects physically resembling coccinellidae (colloquially known as Ladybugs), which at one point includes multiple larval members of the species gathering, spontaneously liquefying into a single mass, then reforming again as adults.
Tracking devices sent along with SCP-389, regardless of whether they are contained within it or simply affixed to its outside, invariably fail after SCP-389 is beyond approximately 100 meters from the shore. All other attempts to track SCP-389 have likewise resulted in failure.

Item #: SCP-395
Object Class: Euclid
Special Containment Procedures: SCP-395 is to be kept in the center of a locked room at least 10 meters wide. No female personnel are to be allowed into SCP-395's room under any circumstances. The room is to be guarded by two male personnel at all times. Any unusual behavior should be reported immediately. Any independent movement on the part of SCP-395 should likewise be reported.
SCP-395 is to be fed one liter of a half-and-half mixture of blood and milk, both taken from the same individual, once a week. Failing to follow a regular feeding schedule will cause SCP-395 to increase its range at a rate of 10 meters per day without food. If it has not been fed for more than one week past its expected time, it will begin to [REDACTED].
Description: SCP-395 is a human fetus, approximately 7 months into its development, contained in a specimen jar. The jar is filled with a standard formaldehyde solution, with traces of blood.
When a female human comes within 5 meters of the jar, SCP-395 is able to telepathically influence her. At that point, the subject will feel a need to remove SCP-395 from its jar, and allow it to feed in the normal manner. All women, regardless of age or medical status, will lactate under this telepathic inducement. Once the milk has been exhausted, SCP-395 will continue to feed, drawing blood and gnawing flesh from the subject. The subject apparently feels satisfaction throughout this process, only understanding what has actually happened when SCP-395 is sated and releases its control.
SCP-395 was taken from a traveling freak show, whose owner had been using it to control women for his own personal use. It was discovered when police tracked the bodies of his victims back to him. One of the arresting officers fell under SCP-395's control, and killed her partner when he attempted to stop her from removing it from its jar. Foundation agents caught the report from the follow up investigation, and acquired SCP-395.
Interrogation of SCP-395's owner revealed little. He had acquired it along with the rest of the show from the previous owner's estate. Documentation included with the estate indicated that SCP-395 had been purchased from a teaching hospital in the early 1900s. No information regarding the parents was included.
Testing by male personnel shows no detectable life signs while SCP-395 is inside the formaldehyde solution in its jar. Only when a female human subject comes within its range does it become active, exhibiting a faint heartbeat and high levels of brain activity.

Item #: SCP-403
Object Class: Safe
Special Containment Procedures: SCP-403 is to be sealed in a steel safe with a combination known only by Dr. ████ ███████. The walls of the safe must be reinforced with fire-retardant material complying with Foundation standard C3/403. The safe will remain under surveillance by 2 armed guards at all times.
Description: SCP-403 is a visually unremarkable naptha-fueled lighter that was discovered in a cafeteria at Site-██. When lit once after a prolonged period of disuse, SCP-403 produces an ordinary flame. However, if ignited repeatedly within 24 hours the flame produced by SCP-403 becomes larger and more violent in nature with each subsequent ignition.
During an experiment a Class-D test subject attempted to light SCP-403 a third time within two hours, resulting in a powerful explosion of superheated gas and plasma. This event destroyed the monitoring equipment within the testing cell, and caused significant damage to the flame-resistant plating lining the walls. Despite this, the subject and the item itself remained virtually unharmed. Radio-imaging has shown the formation of a magnetic field around the lighter, which is hypothesized by researchers to be the cause of this immunity.
The fuel used by SCP-403 to produce the detonations is not known as of yet, if any conventional fuel is used at all. Examination of the item shows that the fuel compartment within SCP-403 is empty; no traces of any combustible compound have been found. Considering this, and the amount of energy initiations are capable of producing, SCP-403 should currently be treated as if using a functionally inexhaustible power supply. Tests to ascertain the exact nature of this power source are ongoing.
Addendum 403-1: Continued experimentation has been authorized for SCP-403, and a designated safe detonation area has been provided for testing. After the third ignition, a Class-D personnel attempted a fourth, which caused an explosion that initially appeared to be a thermonuclear blast. Evaluation of the explosion has demonstrated that it was of equivalent magnitude to 10 MT of TNT, far exceeding the yield of most strategic nuclear weapons; this yield was also far greater than extrapolations based on past tests seemed to suggest. Further study of recorded data seemed to show that the event was actually caused by the release of [DATA EXPUNGED] stellar material. No abnormal lasting effects from the explosion were observed, apart from the devastation wreaked by the initial blast. Once again the subject used to ignite SCP-403 was unharmed by the blast.
Addendum 403-2: All further tests have been suspended due to the extreme danger presented by the high-energy detonations SCP-403 is capable of producing. As it seems the power of SCP-403 increases exponentially, a fifth ignition could result in an event comparable to [DATA EXPUNGED]. A blast of this magnitude could devastate vast portions of the continent and present a severe risk of breaching the containment of several Foundation sites, including [REDACTED].

SCP-409

Item #: SCP-409
Object Class: Keter
Special Containment Procedures: No physical contact may be made with SCP-409 for any reason. Anything making physical contact with SCP-409 must be contained in quarantine immediately, along with any materials used in the transport of the subject. SCP-409 must be kept in a granite case at all times. Any transportation of SCP-409 must be done in a sealed granite container. Residue from SCP-409's effect are to be sealed in granite containers along with any tools used to transport residue into containers.
Description: SCP-409 resembles a large quartz crystal approximately 1.5m (5ft) tall and 0.6m (2ft) wide. Any objects coming in contact with SCP-409 will begin to crystallize after three hours. This effect will occur in any material other than granite. The crystallization will spread by approximately 2.5cm (1in) per minute, and will convert the entire object or organism, inside and out. Subjects report this effect to be extremely painful, and similar to frostbite. After complete crystallization, the object will begin to make snapping and creaking noises for approximately twenty minutes, before bursting into thousands of fragments with great force.
Anything touched by or touching a fragment will immediately begin to crystallize. Nothing at this time is able to reverse the effect in organic matter, including amputation of affected areas. Inorganic matter will only crystallize for a few centimetres around point of contact. SCP-409 was recovered in [EXPUNGED], under a pile of crystal shards several feet deep. Losses of personnel during recovery were high.
Addendum 409-1: With the suggestion of Dr. [500-0021D], Subject 409-D5 was exposed to the effects of SCP-409 and was left to become severely "crystallized". After that he was treated with SCP-500, and a complete recovery was achieved in 9 days. Subject reported that he continued to feel pain in body parts that were "crystallized" even after the estimated recovery time. Pain faded 13 days after subject was treated. It is unknown if the pain effect was psychological or real during the intervening 4 days.
Addendum 409-2: Extensive testing has yielded no information as to why the crystallization occurs. SCP-409 and the shards created by it are indistinguishable from any other quartz crystal. The effect appears to be similar to a seed crystal, where a pre-existing crystal formation is added to a solution, causing the crystal to "grow". SCP-409, however, appears to do this with all solid matter, and does not need to remain in contact. How this is done, why SCP-409 is unique among all other quartz crystals, and why granite is the only material immune are all still unknown.

Item #: SCP-416
Object Class: Euclid
Special Containment Procedures: Owing to its anomalous topographic structure and the danger it poses to civilians, it is essential that SCP-416 be sequestered from the public. Though SCP-416's true borders have yet to be exactly mapped, SCP Overwatch has, in cooperation with the ████████ government, restricted foot access and instituted a no-fly-zone within five (5) kilometers from the boundaries measured by the initial observation team.
Description: SCP-416 is an oblong area of forest located in the █████████ █████████ in northern ████████, ██████ ███████. Though its true borders are not known (and indeed may be in a constant state of flux), estimates place its "center" at ██°██ N, ██°███ W. It displays remarkable spatial anomalies, the most notable of which is that once entered, it is impossible to leave on foot; the only personnel to escape the area inside SCP-416 were extracted by an aerial reconnaissance team. Though from the air SCP-416 appears identical to the surrounding coniferous forests, it displays a bewildering array of plant life; species as varied as Joshua trees (Yucca brevifolia), Grandidier's baobab (Adansonia grandidieri), Wollemi pine (Wollemia nobilis), and manchineel trees (Hippomane mancinella) have been observed. No explanation has been offered as to how these species arrived and propagated. All observations indicate that SCP-416 is entirely devoid of animal, fungal, or insect life. Personnel deployed inside SCP-416 report that the entire area is continually overcast with fog despite satellite evidence to the contrary.
Exploratory Records: On ██/██/████, local geographical surveyors reported a sudden seismic event coming from the area now known as SCP-416. The Foundation was alerted after the surveyors reported anomalous topological features. D-class personnel were fitted with GPS trackers and tasked with walking across the entire area of SCP-416; though the subjects reported that they maintained a constant speed, their movement speed relative to the area outside SCP-416 slowed dramatically as the subjects ventured further in. The deployed personnel were unable to reach the epicenter of the seismic event. The subjects reported no indication of backtracking on their part; it appears that SCP-416 may be infinite in area to observers located within it. The D-class personnel forced to endure prolonged stays inside SCP-416 have developed a wide array of mental instabilities, ranging from depression and post-traumatic stress disorder to catatonia, hallucinations, and psychosis.
Topological Analysis: A team of physicists assigned to analyze the topographical anomalies associated with this SCP concluded that it appears to be the three-dimensional intersection of a six-dimensional Calabi-Yau manifold with the surface of the Earth. Research is still being conducted as to what force maintains this intersection, though speculation abounds that it is related to the object or objects at the center of SCP-416.
Addendum 04-5: SCP-416 is being considered as a storage location for several movable Safe and Euclid-level SCP's, specifically [DATA EXPUNGED].

Item #: SCP-431
Object Class: Euclid
Special Containment Procedures: Backup copies of all Foundation documents are to be kept at Site-██. Any documents and/or photographs SCP-431 is found in are to be stored in the Site-██ local database and replaced with their backup copy. Any personnel who report recalling SCP-431 are to be immediately questioned. Office ██-25 is to be inspected daily for any new objects. Foundation archives are to be monitored for any changes or new documents regarding SCP-431.
Description: SCP-431 is the designation given to Dr. Gideon, a man who appears to have been a Foundation researcher. Due to the condition of records at present, it is not known if Gideon is his real name. The existence of SCP-431 was first discovered during what appeared to be an attempt to hack the Foundation database: a number of documents were altered to state that a scientist referred to as "Dr. Gideon" was involved in researching several SCP objects. However, it was determined that the documents in question were not being accessed at the time that they were modified.
Since the initial event, references to a Dr. Gideon have appeared in ██ additional documents. Every time a document has been altered, it has been shown that it was not in use at the time of modification. Several new documents also appeared, a number of which are SCP documentation of items that the Foundation does not currently possess, including a [DATA EXPUNGED], and one item, a [DATA EXPUNGED], which is known to currently be in the possession of Marshall, Carter, and Dark Ltd.
A number of objects have also been discovered in Office ██-25, which is currently vacant. It is not known when items began to appear inside it, as the office was only investigated when a "Dr. Gideon" name placard appeared on the door. ██ documents have been recovered from the office, including a photograph, Document 431-██ which is believed to depict Dr. Gideon alongside three (3) known Foundation personnel. Security camera tapes dated ██/██/██ show a man who is believed to be Dr. Gideon conversing with a number of researchers. None of the researchers report ever working with anyone named Gideon and none show signs consistent with the administration of amnestics.
No information concerning Dr. Gideon's hiring by the Foundation exists, nor does any documentation indicating that Dr. Gideon was either fired, terminated, or quit. One document recovered from Office ██-25 appears to have his fingerprints on it, as the fingerprints have no match within the Foundation's or any government's fingerprint database. No government documentation regarding anyone named Gideon matching the description of the individual in Document-431-██ exists, including birth, death, census, or tax information.
By date, the last documents available presently state that Dr. Gideon was scheduled to oversee the neutralization of an SCP object; however, the document refers to the object being neutralized as SCP-███, a designation not currently in use. No documentation has appeared describing SCP-███.
