Those subject to 562-Claim events are found dead in the nearest 
old-growth forest at some point between four and eight years later. 
Autopsies reveal the causes of death to be multiple organ failure 
consistent with advanced age. In most cases, a large, though safe, 
quantity of honey, milk, and alcohol is found in their digestive tract. 
Attempts to trace the origin of this honey have proven unsuccessful 
to date. These corpses are found dressed in ornate and unlabeled 
clothing of extremely high quality. Rarely, the subject retains some 
item they possessed at the time of the 562-Claim event. Such 
objects show wear consistent with decades of use. 


It is estimated that no more than forty successful 562-Claim events 
occur each year, of which the Foundation is aware of roughly a third 
within a week of the body being found. The annual number of 
unsuccessful events is harder to estimate as these generally go 
unreported, but it is believed number less than a thousand. 
Demographically, victims of SCP-562 tend to be about 40% male 
and 60% female, mostly in the age range of 13-22. SCP-562 may 
apparently manifest in any internet chat site, but tends to target 
European ones. 


Addendum 562-15: In light of the recent batch of seventeenth- 
century letters published by the Royal Historical Society, it is now 
believed that SCP-562 is not a new phenomenon. One exchange in 
the release is between a Lady Marchgrove and a Dick O’Dale, in 
which the latter attempts to convince the former to attend a ball he is 
throwing. Lady Marchgrove agrees to go, and historical records 
indicate her disappearance at about the same time as the last letter 
is believed to have been written.

subjects exposed to SCP-1974-EX and not offered intentional or 
unintentional behavior suggestions. 


It is currently being investigated whether the effects of SCP-1974 
are chemical, memetic, or supernatural. 


Analysis has determined that in SCP-1974-EX, the ABS has been 
combined with [REDACTED], a solvent and carrier similar to 
Dimethyl sulfoxide (DMSO), but solid at room temperature. This is 
used to introduce a dose of an r-Ergotamine derivative, a long-acting 
hallucinogen. In addition, SCP-1974-EX contains a transmitter 
emitting non-audible sounds at frequencies of [REDACTED], 
generating a psychoacoustic effect that combines with the 
hallucinogen to cause extreme suggestibility in SCP-1974-EX- 
exposed subjects. 


Since SCP-1974-EX is merely a novel means of hypnotizing 
subjects and secretively dosing them with hallucinogens, it is hereby 
declassified as an SCP and removed from the main SCP database 
as of 08/16/1992. Collection of further uncontained specimens is 
now a police matter and will not be conducted by Foundation 
Agents. 


Due to the potential uses in clandestine activities and humanoid 
SCP control, Foundation Research and Development has 
requisitioned the supply of SCP-1974-EX, and is developing the 
means to reproduce its effects in different formats. ! 


Addendum: SCP-1974-EX came to the Foundation's attention 
when a large quantity were distributed as free samples during 
[REDACTED] Con, a Science Fiction and Fantasy convention held 
in , on/ - /19 . Over 200 individuals were detained after 
exhibiting bizarre behavior resulting in fatalities, injuries, and 
numerous incidents of property damage and disorderly conduct. 
specimens of SCP-1974-EX were confiscated, and the incident 
attributed to mass hysteria caused by an unusual variety of food 
poisoning. 


Incident Log 1974-01: The following is an excerpt from a list of 
incidents reported shortly after the initial release of SCP-1974-EX to 
the public. It demonstrates that while many affected subjects engage 


in harmless but absurd behavior, others pose a danger to 
themselves and others, especially to unsuspecting or defenseless 
persons. 


° ; severely beat Hotel doorman; believed victim was 
“an orc.” Subject successfully restrained with minor injuries. 


° ; restrained while “casting a fireball” by chanting in an 
unknown language, waving a pool cue, and burning a carefully 
arranged circle of kitchen spices. No injuries reported. 


° ; Claimed to work for [REDACTED] after playing a 
game of “Paranoia”; interrogated and released when it was 
determined that subject had no knowledge of genuine 
classified information. 


° ; killed by police after charging a group of officers 
with a butcher knife, while shouting “Blood for the Blood God!” 


. ; attempted to sacrifice his sister to “summon Yog 
Sothoth” after playing “Call of Cthulhu”. [DATA EXPUNGED]. 


The source of SCP-1974-EX remains unknown. Relevant 
information anonymously transferred to , Police Department 
for continuing investigation.

SCP-1933-EX: Lake Monster 


Item #: SCP-1933-EX 
Object Class: Euclid Explained 


Special Containment Procedures: Lake is to be monitored for 
appearances of SCP-1933. Civilians approaching the Lake are to be 
turned away on the grounds of the area being scouted out for 
construction. Due to SCP-1933's memetic effects, removal from the 
Lake is highly unlikely to occur. Individuals who claim to have seen 
SCP-1933 are to be administered Class A amnestics, and released. 
Personnel being transferred to research SCP-1933 are not to be 
informed of SCP-1933 or any documentation regarding it until they 
have observed SCP-1933 firsthand. Individuals discovering this 
document without having first seen SCP-1933 are advised to 
immediately exit this document, and contact Dr. B. Reynard as soon 
as possible for Class A amnestics, or observation of SCP-1933. No 
special containment procedures are required for SCP-1933-EX at 
this time. Distribution of Class A amnestics to subjects who claim to 
have observed SCP-1933-EX is currently discontinued. 


Description (REVISED): SCP-1933-EX is allegedly a creature 
measuring an estimated 6 to 8 meters in length, residing in Lake 

, British Columbia. Exact details vary from report to report, but 
SCP-1933-EX is almost always reported to have a long, serpent-like 
neck and head, a similarly long tail, dark blue coloration, and long, 
leaf-like protrusions running from the base of its head to the end of 
its body. However, SCP-1933-EX has been, in each report of 
sighting, quickly determined to have been a misidentified common 
occurrence, such as a large piece of driftwood, large eel or fish, or 
simple unreliable testimony. Recovered ‘footage’ of SCP-1933-EX 
has been easily explained by photo or video manipulation, or 
intentional staging to simulate an SCP-1933-EX encounter. It is 
most likely that reports of SCP-1933-EX are the result of subjects 
being influenced by local myths and legends. 


+ Show original documentation for SCP-1933-EX 


Description: SCP-1933 is an unidentified aquatic 
creature, measuring an estimated 6-8 meters in length, 
residing in Lake , British Columbia. SCP-1933 is 
dark blue in coloration, possessing a long, smooth neck 
and tail, a serpentine head, and numerous leaf-like 
protrusions running from the base of its head to the end 
of its body. Details regarding the lower half of 
SCP-1933's body are predominately unknown, as it has 
never been observed to beach itself, or surface more 
than its neck and upper half of its body. As SCP-1933 
does not appear to possess gills, it is currently theorized 
to reside in an underwater cave, which is currently being 
searched for using sonar. SCP-1933 has been observed 
camouflaging itself with aquatic plants or fallen trees, 
and ambushing large prey that approaches the water, as 
well as preying on passing birds and fish. SCP-1933 has 
been observed to actively avoid boats in most situations, 
but has occasionally attacked solitary humans entering 
or around the lake. 


SCP-1933 possesses a secondary effect, possibly 
memetic in nature, that causes those who become aware 
of it from any method except firsthand experience, 
(including documentation, personal testimony, or video 
or photo evidence) to become extremely unwilling to 
consider its existence. This can include finding flaws ina 
subject's testimony that are not actually present, seeing 
‘wires’ 'animatronics’, or '‘photo-manipulation' where none 
are present, or verbally shutting down conversation 
regarding SCP-1933. This is thought to be the result of a 
defense mechanism designed to keep potential prey 
from becoming wary of approaching the lake. While this 
has caused significant delay in documentation and 
observation of SCP-1933, it has expedited ensuring 
civilians do not become aware of SCP-1933. At time of 
writing, only a small group of researchers are aware of 
SCP-1933, and a way of informing the rest of the 
Foundation of its existence, allowing more effective 


containment, is being researched. 


Note: On //  ,an experiment with the intent of proving 
the existence of SCP-1933 to the rest of the Foundation 
will take place. SCP-1933 will be lured to the surface 
using the carcass of one elk, deposited in the middle of 
Lake by boat. Dr. Reynard will then contact MTF 
Eta-10 ("See No Evil") and attempt to live stream an 
appearance of SCP-1933 directly to them. If this is a 
success, then we will have taken the first step in 
successfully containing SCP-1933. If not, then we're 
probably going to all be brought in for questioning and/or 
amnestic treatments. Either way, it's been a pleasure 
working with you all. - B. Reynard 


Addendum: SCP-1933-EX was reclassified to 'Explained' after a 
group of researchers led by Dr. B. Reynard contacted MTF Eta-10 
("See No Evil") claiming to have evidence of a possible new 
cognitohazardous entity, which would be demonstrated to them over 
a private internet live stream. Eta-10 personnel viewing the live 
stream reported that the researchers had constructed an 
animatronic to resemble the entity they were referring to, which rose 
out of the lake and dragged under the carcass of an elk. These 
researchers were quickly located and brought in for questioning. Dr. 
Reynard was reprimanded for abuse and waste of Foundation 
resources. 


Dr. Reynard was discovered to have been drowned in Lake 
roughly a week after the reclassification of SCP-1933-EX in an 
unrelated boating accident’. Allegations that Dr. Reynard appeared 
to have been (sic) 'half-eaten'’ are currently under investigation. 
Official cause of death is believed to be drowning after extensive 
blood loss due to injury from a boat propeller. 


Footnotes 
1. The location of the boat used by Dr. Reynard is unknown, and 
there are no reports of Dr. Reynard buying or renting a boat prior. 


SCP-1512-EX: 3D Bioprinting 


An example of downstream technology utilizing SCP-1512-EX 


Item #: SCP-1512-EX 
Object Class: Safe Explained 


Special Containment Procedures: All instances of SCP-1512 are 
to be kept at Site-66, under modified P4 conditions (all materials 
related to SCP-1512 are handled similarly to P4 pathogenic 
material, and SCP-1512 itself is kept in a ISO Class 1 cleanroom 
environment). All related products and byproducts of SCP-1512 are 
to be disposed of utilizing P4 procedures for disposing of laboratory 
waste. Rescinded, refer to Addendum 1512-03. 


All personnel working with SCP-1512 are to undergo weekly medical 
tests and laboratory examination to ensure that no accidental 
infection by SCP-1512 is carried outside of the containment/ 
research facility. Personnel who have been infected by byproducts 
of SCP-1512 are to be contained and treated with mitotic inhibitors 
(vinblastine or vincristine) for a period of no less than 28 days. If 
SCP-1512 byproducts have not been cleared out of the infected 
personnel's system after the 28 day treatment, termination via fire is 
to be carried out. Rescinded, refer to Addendum 1512-02. 


No current special procedures exist for containment. SCP-1512-EX 
is to be kept in an ISO Class 1 cleanroom at all times. Research 
proposals involving SCP-1512-EX are to go to the project head, who 
at the time of this writing is Doctor G. Hewlett. Refer to Addendum 
1512-04. 


Description: SCP-1512 are six (6) electro-mechanical devices, 
capable of artificially creating cellular matrices resembling functional 
human organs when provided with proper cellular material and 
growth media. 


All recovered devices operate in the following matter: 


* Areservoir of cells (embryonic stem cells at the time of 
recovery) is kept in fluid suspension; 

* The device, a modified CNC routing machine, moves into 
position where cells are required over a growth medium; 

* As the device head passes over the growth medium, a 
stepper motor turns a screw, that extrudes the cellular 
material over the growth medium; 

« When a layer is complete, a support plate lowers gradually, 
allowing for a 3D model to be built from living cells. The 
machine stops once the entire model has been completed. 


Biological structures created with embryonic stem cells require an 
external stimulus to influence the cell type, but adult stem cells 
appear to be easier to influence and control with respect to desired 
cell type. Refer to Addendum 1512-02 for details. 


SCP-1512 is compatible with running the G-code (RS-274) 
numerical control language, which is used to operate most 
computer-aided manufacturing (CAM) machines and devices. 


Recovery: All instances of SCP-1512 were recovered from an 
abandoned Prometheus Labs facility following the company's 
collapse in. All devices, software, and incomplete technical/ 
testing data were recovered without incident, and all material was 
transferred to Site-66 for processing and containment. 


Addendum 1512-01: Due to the usage of embryonic stem cells, 
there is a concern that biological structures created by SCP-1512 
may result in potentially deleterious objects being created. Object 
containment class remains at Safe, but handling procedures now 
formally adopt P4 procedures for handling all products and 
byproducts of SCP-1512. 


Addendum 1512-02: As part of an experiment proposal to replace 
Agent [REDACTED]'s index fingertip (which was lost during a field 
mission), one unused instance of SCP-1512 was prepared with adult 
stem cells derived from said agent's bone marrow, and an artificial 
bone and tissue construct was created. Following successful 
attachment/revascularization surgery and no signs of mutation or 
other deleterious side-effects, SCP-1512's P4 status has been lifted, 
and research may continue at a lower protection level. 


Addendum 1512-03: Following the news of biomedical research 
company Organovo developing its own process for safe bio-printing 
in 2007 (in conjunction with the University of Virginia), Foundation 
agents have obtained copies of Organovo's notes to compare to 
extant instances of SCP-1512. Finding strong similarities between 
Organovo's notes and notes corroborated by research into 
SCP-1512, the Overseer Council has decided to officially re-classify 
SCP-1512 as Explained, as the technology utilized in creating 
SCP-1512 is now considered advanced scientific knowledge rather 
than anomalous phenomena.
