Silence for 30 seconds. During this time, 
SCP-1864-1 extends its appendage into the 
pool, where it continues to extend until 
disappearing. SCP-1864-1 is observed 
watching the water. 


SCP-1864-1: Something foul that we dragged 
out of the sea. Something that should have 
stayed in the darkness forever.

Addendum 3: Additional Collected Logs 
+ Access Log 


The following information was collected during initial 
exploration of SCP-1864. What follows is an excerpt 
from the scientific journals of a Dr. Gregory Groswald, 
German scientist during World War I. Translations have 
been provided where necessary, and irrelevant 
passages have been removed for brevity. 


August 15th, 1916 


A commotion in the market today. One of the 
fishing vessels pulled a small child out of the 
ice. Doctor Mans initially declared the boy 
dead, but discovered he still drew breath! 
Miraculous, and in no way unrelated to the 
anomaly of our study, | believe. | will visit the 
boy when he becomes healthy. 


August 19th, 1916 


The boy is pleasant enough, although 
speaking with him has become an 
inconvenience. The boy claims that he is 
called Pan Hun, but cannot seem to form 
sentences without switching between a 
number of languages. Whether this was taught 
to the child, or a matter of some other nature, 
is currently unknown to me. Doctors Mans 
claimed the boy is sickly, however, and is not 
certain if he will last the winter, much less the 
month. 


August 27th, 1916 


Another miraculous event surrounding our 
mysterious Pan Hun. All of the patients at the 
medical center have been released, their 
symptoms vanishing overnight. When pressed, 
all of them claimed that Pan Hun came to them 
while they slept, and touched their skin. A 
number said that the boy simply looked at 
them, and they became well. Doctor Mans is 
aghast, and | must say that | do not blame him. 
| have arranged another meeting with the boy, 
with Doctor Boff accompanying me. We will 
get to the bottom of this. 


September 2nd, 1916 


It may be a miracle after all. The boy claims 
that he is a messenger from God Almighty, 


and that his arrival will signal the dawn of a 
new Jerusalem in our country. He speaks of 
peace eternally, and end to sickness and war, 
and the glory of Germany and the Kaiser! After 
seeing the works of his hands, | no longer 
have any reason to doubt. We will bring this 
child back to Berlin when the next ship arrives, 
and we will secure the glorious victory for the 
Fatherland. This boy Pan Hun will be our 
salvation!

SCP-1865: TaoTao 


Item #: SCP-1865 
Object Class: Safe 


Special Containment Procedures: SCP-1865 is to be contained 
inside of a humanoid containment unit that has been immersed in 
seawater. SCP-1865 is to be positioned at the center of this room, 
with weights preventing it from achieving an ambulatory state. Entry 
to SCP-1865's containment cell is to be restricted via an airlock. If 
SCP-1865 must be removed from its cell, it is to be transported with 
a steel 1x0.5 meter transport container. 


Description: SCP-1865 is an entity residing in a deep sea diving 
suit, approximately 1.2 meters tall and weighing 150 kilograms. 
What is assumed to be a mouth similar in appearance to that of a 
cephalopod is visible within the porthole; this structure opens and 
closes intermittently. The suit SCP-1865 resides in appears to have 
been manufactured by an unknown party at some point between 
1955 and 1965. 


The suit is airtight and filled with seawater, containing traces of 
vegetation and watercraft debris. When punctured, the suit is sealed 
from the inside with a fleshy substance assumed to be an extension 
of SCP-1865. This sealing process takes approximately five 
seconds during most testing attempts, and is present throughout the 
suit. It is possible to remove portions of SCP-1865 from the suit, 
although contact with open air appears to damage the object and 
cause the exposed sections of SCP-1865 to immediately calcify. 


SCP-1865 achieves mobility via a series of pipes and valves that 
have been integrated into the suit. This system will take in and 
release seawater in a way that causes SCP-1865 to move at a slow 
gait when underwater. Inspection of the pipes’ interior via fiber optic 
cameras has shown that the pipes leading from the valves are 
translucent and appear to be composed of organic material. 


Inspection is limited due to damage caused to the cable during 
observation. 


The suit is divided into 7 sections, including the abdomen, head, 
arms, hands, feet, chest, and legs. These dividers in these section 
act as main points for valves, and are composed of a chitinous 
material. Detailed descriptions of these areas and their contents are 
listed below. 


Universal contents: All sections of the inside walls of SCP-1865 
are covered in a thin layer of organic material, this surface is dotted 
with nodules containing multiple aquatic biological entities referred 
to as SCP-1865-2.1 Instances of SCP-1865-2 are lodged within 
breached suit sections. All instances of SCP-1865 are deep ocean 
organisms. 


Chest: Approximately 80 semisolid, translucent spherical structures 
suspended in the center containing instances of SCP-1865-2. 
Structures appear to vary slightly in color, with smaller, less 
saturated structures containing additional instances of SCP-1865-2. 


Arms/Legs: Contains the majority of the bladder like structures 
used for maintaining and releasing pressure within different sections 
of the suit. The nature of these structures appears to be mechanical, 
as different flagella located on these nodules can be seen being 
manipulated by instances of SCP-1865-2 to cause changes in 
pressure. 


Abdomen: An unknown quantity of SCP-1865-2 organisms 
superficially resembling Macruronus novaezelandiae. Any foreign 
matter introduced to SCP-1865 or waste created by SCP-1865-2 
entities will be sent here. The SCP-1865-2 organisms excrete an 
acidic liquid which breaks the matter down into base proteins. 


Hands/Feet: Contains extremely sensitive SCP-1865-2 organisms. 
These organisms react to changes in light and any pressure applied 
to SCP-1865. They are also able to cause SCP-1865-2's hands to 
retract into fists, exerting 350 psi of pressure on anything it can 


grasp. 
Helmet: Contains SCP-1865, an entity resembling a cephalopod. 


Occasional retractions by SCP-1865 has allowed the interior of the 
helmet to be observed, the helmet contains small amounts of gold 

leaf, a large amount of nutritional matter, and several instances of 

SCP-1865-2 assisting SCP-1865 with its biological functions. 


SCP-1865 was recovered from the southern beach of Tanapag, 
Saipan in 1979, when it came ashore near the village of 
[REDACTED]. When villagers attempted to approach SCP-1865, it 
began emitting low-pitch vocalizations, and attempted to grip the 
hand of the village leader. SCP-1865 crushed the leader's hand, 
causing the villagers to take it captive and contact local authorities. 
Foundation personnel embedded in the Saipan government were 
able to confirm SCP-1865's anomalous properties when it came into 
the governments possession. Villagers and Saipan government 
officials were issued Class-C amnestics. SCP-1865 was contained 
on 4/16/1979, and classified as Safe.

SCP-1866: The Phone Bill 


Item #: SCP-1866 
Object Class: Safe 


Special Containment Procedures: Since 2 July 2010, SCP-1866 is 
stored at Site 20, Building C, room 184A, in a cardboard box 
measuring 140 cm x 140 cm x 146 cm. The box contains a card 
table 137 cm wide, 137 cm long, and 71 cm tall. An envelope has 
been stapled to the center of the table and is to remain so at all 
times; SCP-1866 is to be placed inside the envelope when not in 
use. Pictograph stickers depicting the type of hazards (118 Data 
Corruption; 003 Self-Propagating) and means of activation (005 
Proximity) are affixed in a prominent location on the box's exterior. 


The entrance to the containment room must have a sign warning 
visitors to leave all objects, including writing implements and 
clothing, outside of the room. Employees with certain kinds of 
prosthetic devices or tattoos are prohibited from viewing or 
experimenting on SCP-1866 under any circumstances, by order of 
05-2. (For a complete list of personnel restrictions, see Document 
1866-01.) Room 183A contains unmarked surgical scrubs, a 
changing area, and lockers for researchers' personal items. 


All records in the containment room or adjacent rooms must record 
dates using the name of the month (e.g. "November") instead of 
abbreviating it as a number ("11"). 


Researchers wishing to bring any object (including experiment logs) 
into the containment area, or wishing to conduct any experiments 
involving SCP-1866, must first receive permission from the level 4 
researcher responsible for Building C. 


Description: SCP-1866 is a single piece of paper, measuring 21.6 x 
27.9 cm, visually indistinguishable from a bill from telecom provider 
[REDACTED]. When it comes within approximately 60 cm of 


susceptible dates and/or times written in certain formats, it alters 
said dates and times in a specific and predictable pattern, 
overwriting magnetically-stored data and physically altering printed 
or handwritten data. (Interested personnel are directed to Appendix 
1866-A below for information on the pattern of date alterations. This 
knowledge is not necessary for containment, but may be valuable to 
personnel wishing to make their personal documents more resistant 
to SCP-1866 containment breach.) Human memory is unaffected by 
SCP-1866. 


Altered documents and devices can propagate the effect to others, 
though with a smaller and more variable range (measured between 
31 and 40 cm). Wireless networks, fiber-optic cable, and other forms 
of long-distance data transmission do not appear to act as vectors. 


The effect is transmitted instantaneously and has not been blocked 
or attenuated by any material tested to date. 


When isolated, affected items lose their ability to soread the effect, 
and are effectively neutralized within 48 hours; however, 1) the data 
in a neutralized item remains altered, and 2) adjacent affected 
objects continuously re-affect one another unless placed outside 
one another's radius of influence. Successful neutralization therefore 
requires the separation of affected objects from all others by a 
distance of at least 40 cm for at least 48 hours.’ Neutralized objects 
are no longer vulnerable to the effect unless a new time or date is 
written on or encoded in them. 


SCP-1866 itself is always capable of altering susceptible objects 
and cannot be neutralized. 


Recovery Log: 

The case which led to recovery of SCP-1866 began on Tuesday, 
July 21, 2009, in Oxford, IL, a former town of about 15,000 people 
located in Whiteside County, Illinois. A single individual retrieved 
SCP-1866 from his mailbox, transmitting the anomalous effect to his 
driver's license and cell phone, then went to his office at 9 AM. The 
effect spread immediately to multiple objects within his cubicle and 
neighboring cubicles, then more slowly as employees moved around 
the office. 


By approximately 10:15 AM, several employees were 
simultaneously contacting technical support (for computers) and 
HVAC repair (for the office thermostat). The number and content of 
these calls were flagged by voice-recognition software wiretaps as a 
possible anomalous object situation, and the Mobile Task Force 
Mu-4 ("Debuggers") was alerted. 


MTF Mu-4 arrived at [REDACTED] at 12:05 PM. Because the nature 
of the event and the circumstances by which it was spread were 
initially unclear, and because the effect slowed agents’ ability to 
communicate, city quarantine procedures were not initiated until 
12:43 PM on 21 July. The quarantine was maintained for four days 
while agents determined what had happened, during which time the 
effect continued to spread within the town, resulting in: minor 
disruptions to local telephone service and traffic; significant 
disruptions to emergency services, medical care, and government 
function; near-total disruption of electrical service;2 and near-total 
disruption of banking and commercial services.3 


A total of 24 individuals lost their lives as the result of SCP-1866.4 


Agents provided regional, state, and national media with a slightly 
altered version of Cover Story 24A to explain the quarantine and 
subsequent destruction of the town. Persons known to have been 
present in the [REDACTED] office during the initial outbreak were 
questioned prior to relocation, enabling Agents to identify the initial 
carrier of SCP-1866. Residents were then given Class A amnestics 
and relocated to Foundation Communities Kilo and Lima. All 
structures and objects within the town, save the objects in the initial 
carrier's home, were examined for data relevant to the investigation, 
then either incinerated or pulverized, over a period of 3 weeks. 
Razing of structures required an additional 2 weeks. Cartographic, 
historical, and governmental records have been altered when 
possible, with the permission of the relevant authorities.° 


The initial carrier of SCP-1866's effect was interrogated by 
Foundation agents from 23 July until 4 August. He maintained 
throughout interrogation that he had no knowledge relevant to the 
origin or function of SCP-1866, nor could he think of a reason why 
anyone would wish to make it appear that he did. All five agents 
involved in his interrogation concluded that this is likely true (q.v. 


Interrogation Report 1866-01). On August 5, 2009, the recipient of 
SCP-1866 was given Class A amnestics and relocated to a 
Foundation community. All of his personal belongings were 
collected, transferred to Site 90, cataloged, and tested for SCP-1866 
activity. 


Due to the extremely large number of items collected and the extra 
effort necessary to prevent contamination of Foundation information 
during cataloging, several affected items were no longer active by 
the time they were tested, leading researchers to the realization that 
the effect's contagiousness decays with time. Subsequent 
experimentation resulted in the neutralization of all affected objects 
except the original, which was revealed as SCP-1866. 


The origin of SCP-1866 remains unclear. The paper stock, graphics, 
and envelope are consistent with that typically used by the utility. 
The phone calls recorded on the bill are likewise consistent 
(accounting for alterations introduced by the anomalous effect) with 
utility records. Neither SCP-1866 nor its envelope contains any 
unusual markings. The envelope bears a 20 July 2009 postmark, 
from the Sterling, IL Post Office, consistent with the utility's billing 
cycle. The original envelope has no ability to block the effect of 
SCP-1866, as determined from testing, but no similar outbreaks 
have appeared in Sterling or elsewhere in the country, leading to the 
conclusion that the anomalous effect was introduced after the bill left 
the Oxford Post Office. 


NOTE: Two of the nine agents who contributed to this report 
hypothesize that SCP-1866 was a trial run by an unknown terrorist 
group, and the effect was not necessarily intended to spread beyond 
Northwestern Illinois. A group seeking maximum spread in 2009 
would have chosen a release date in March (3/09), June (6/09), 
September (9/09), or December (12/09). 


No similar objects have been reported since 2009. 
Appendix 1866-A: 


Data altered by exposure to SCP-1866 is affected when 
the following conditions apply: 


1. The data represents a date or time. 

2. The data is represented as a set of integers, at 
least two of which are not zero.
