Description: SCP-3666 is an allergic inflammatory 
reaction to the presence of amnestic proteins and 
substances within the bloodstream of affected 
individuals. Immune systems modified by SCP-3666 are 
unable to change or adapt to both normal anti-allergy 
treatments and those developed by the Foundation. As 
of now, no gene or allele has been correlated to the 
creation of SCP-3666 within the genome of affected 
individuals. 


Individuals affected by SCP-3666 show regular 
symptoms of digestion or skin related allergies when 
exposed to Class-B to Class-F amnestics which are 
ingested or inserted into the patient. Individuals affected 
by SCP-3666 show symptoms of respiratory related 
allergies to Class-A amnestics which are inhaled. 


Affected immune systems effectively eliminate all 
amnestic substances while inside or before they can 
reach blood vessels within the brain. Due to this effect, 
all affected individuals are effectively impervious to the 
main effects and side-effects of all amnestic treatments. 
SCP-3666 is capable of adapting and modifying the 
central nervous system to protect it from memetics and 
cognitohazards which target regions of the brain 
processing long-term and short-term memory. 


If an individual comes within a 30 meter area of an 
individual affected by SCP-3666, the healthy individual 
will be contaminated by SCP-3666. This area is 
expanding in size since its discovery. The growth of the 
area is not proportional to its time of growth, it is 
accelerating rapidly. No direct causes to SCP-3666 have 
been found. All attempts to reengineer immune systems 
to suppress SCP-3666 have failed. Immune systems of 


subjects have become stronger following these attempts. 


SCP-3666 is capable of reconnecting memories to the 
central nervous system following its infection of 
amnesticized individuals with standard amnestics. 
Standard amnestics only "freeze" and isolate certain 
parts and memories of the brain to produce memory 
loss. SCP-3666 has recently been discovered to reverse 
the aforementioned amnestic treatment. 


As of 01/01/2021, only nine areas remain unaffected by 
SCP-3666, these include: 


* Greenland (Denmark) 
* Canada 
* Siberia (Russia) 


* Iceland 


Svalbard (Norway) 


French Polynesia (France) 


Antarctica 


¢ Alaska (United States) 


Franz Josef Land (Russia)

We have tried so many ways to cure 
SCP-3666, to find a way to stop its spread, but 
we failed each time. We have tried to connect 


it with some imperfections within the human 
DNA, but to no avail. We have blamed memes, 
viruses, and bacterias, but there were no 
scapegoats to burn. There is no cure, no 
vaccine, no gene or brain editing that can be 
made. There is only SCP-3666 and we are 
powerless against it. 


Many of our SCPs cannot live within the 
conditions imposed by regions of the world 
which aren't affected by SCP-3666. With the 
exception of French Polynesia, they're 
desolate and cold environments. Another 
problem arises when sites centered around 
location-based anomalies are infected by 
SCP-3666. 


We will find new ways to fight SCP-3666. The 
world is still not ready.

SCP-474: Broken Mason 


Item #: SCP-474 
Object Class: Euclid 


Special Containment Procedures: Instances of SCP-474 are to be 
contained in high-capacity vaults, located in Site-77's Euclid 
wing. Each instance is to be suspended in a block of ice which 
encompasses the instance's mass. If an instance of SCP-474 is 
located outside of containment, all cavities will be temporarily filled 
with cotton until it can be fully contained. 


Instances of SCP-474-1 are to be suspended in ice, and held in 
standard containment chambers. 


Description: SCP-474 is a phenomenon which affects the walls of 
artificial structures, characterized by the appearance of a hole of 
varying size and shape. Currently, 34 instances of SCP-474 have 
been contained by the Foundation. 


Structures affected by SCP-474 will generate humanoid figures, 
which are composed out of the same material as the structure 
SCP-474 is affecting. These figures are classified as instances of 
SCP-474-1. SCP-474-1 will slowly fill whatever space the SCP-474 
instance has caused, and will become animate after taking up all 
available space in the area. During this growth period, SCP-474-1 
will resemble the prenatal development cycle, initially appearing as 
an infant before growing into an adult form. 


When animate, instances of SCP-474-1 will seek out the nearest 
damaged artificial structure. Once they do so, they will perform 
various rituals on or around the damaged structure. Examples of 
these rituals include: 


¢ Attempting to gently rub mortar or other sealants into cracks 
or small damaged portions of the structure 


to suppress SCP-3666 have failed. Immune systems of 
subjects have become stronger following these attempts. 


SCP-3666 is capable of reconnecting memories to the 
central nervous system following its infection of 
amnesticized individuals with standard amnestics. 
Standard amnestics only "freeze" and isolate certain 
parts and memories of the brain to produce memory 
loss. SCP-3666 has recently been discovered to reverse 
the aforementioned amnestic treatment. 


As of 05/12/2023, SCP-3666 contaminates the entire 
world population.

Incident-A (12/01/2025): Several Level 1-2 Clearance 
personnel were made aware of 27 controversial O5 
Council documents due to a breach of information from 
the Foundation archives. All members of the former O5 
Council were executed before Foundation forces were 
capable of overcoming the attack. Further methods to 
protect the O5 Council and critical files have put in place. 


Incident-B (09/01/2029): The entirety of Site-87 and 
Area-45 were exposed to broadcasts of a Level 4-5 
Clearance meeting from an unknown source. To avoid 
an attack similar to Incident-A, all personnel having 
viewed the broadcast were executed by a firing squad 
with the exception of Level 4-5 personnel. Executed 
personnel within Site-87 and Area-45 were replaced. The 
decision destabilized relations between higher and lower 
personnel following breaches of information of the event. 
Terminating lower personnel made aware of the event is 
still in question. 


Incident-C (05/05/2031): The population of Turkey, 


France, Norway, and Australia were made aware of the 
Foundation's existence through several breaches of 
information on their respective internet networks. 
Aforementioned information was published by Dr _,a 
Foundation insider who was later found and executed. 
All mentions of Dr __'s reports were rapidly removed. 
The information was memetic in nature; informed 
individuals were unable to forget or believe that the 
information was false. Several counter-memes were 
initiated, all were unsuccessful at preventing 
destabilization of governments and government trust 
within the aforementioned countries. Sites, areas, and 
Foundation officials were relocated. 


Incident-D (07/09/2035): The Ethics Committee was 
charged for several crimes of fraud, corruption, and high 
treason against the O5 Council and the Administrator. All 
of its members were executed. The Ethics Committee 
was reformed under stricter guidelines. All decisions 
concerning administrative laws or executive orders 
proposed by the Ethics Committee are to be reevaluated 
by the O5 Council and the Administrator. In order to 
replace roles maintained by the Ethics Committee, the 
Administrator was given supplementary and emergency 
powers within the council.

SCP-3667: All's Well that Ends Hell 


Item: SCP-3667 

Object Class: Keter Thaumiel 

Special Containment Procedures: 
Display initial containment procedures 


SCP-3667 is to be continually monitored by members of 
MTF Chi-5 (“Solomon’s SEALs”), with additional 
personnel requested from Site-574 as necessary. As of 
14/01/2012, the Mirny mine has been outfitted with 
surface-to-air missile systems around its perimeter, to 
eliminate potential SCP-3667-1 instances; civilians are 
discouraged from entering the grounds on the pretext of 
unstable terrain, and will be detained and amnesticized if 
discovered trespassing. Any potential excursions into 
SCP-3667 must be approved by both the Site-574 
Director, currently Ndeye Bocoume, and the Regional 
Administrator, Angelina Mikhailova. 


Display current containment procedures 


Due to the large Foundation presence within SCP-3667, 
as well as the continued cooperation of sentient sub- 
instances, containment procedures have been reduced 
accordingly. MTF Chi-5 will continue to exterminate any 
non-compliant or non-sentient SCP-3667-1 sub- 
instances that pose a threat to Foundation personnel, but 
their duties have been expanded to include: a) mapping 
and analyzing SCP-3667’s topography and composition, 
and b) determining methods of utilizing SCP-3667-3 to 
contain existing SCPs. 


Description: SCP-3667 is a spatial anomaly located within a 
sinkhole at the bottom of the “Peace” kimberlite diamond mine 
(commonly referred to as the Mirny mine) in Mirny,! Sakha Republic. 
Although ground-penetrating radar and magnetotelluric imaging 
techniques do not reveal any unusual structures below the mine or 
the town of Mirny, the sinkhole contains a Leibniz-class2 spatial 
anomaly, approximately 5km at its widest point and 6km at its 
highest point, consisting of a subterranean network of caves and 
passages, which contain: 


¢ A variety of stone structures and complexes, usually crudely 
built; 

* To date, 24 unique species, classified as SCP-3667-1a 

through -1x. Certain species are sapient, and the vast majority 

are anomalous. All species display hostility to humans, 

especially those of Russian descent; 

To date, approximately 12,000 anomalous human beings, 

classified collectively as SCP-3667-2, most suffering from 

varying degrees of psychological stress; 

A variety of machinery, mostly wooden, designed to imprison 

and/or torture humans or humanoid figures, classified as 

SCP-3667-3. 


Discovery: The sinkhole containing the entrance to SCP-3667 was 
formed on 17/12/2010, when workers at the Mirny mine performed a 
routine drilling operation. When the drill unexpectedly encountered 
the spatial anomaly and penetrated the cavern system of SCP-3667, 
the resulting cave-in killed at least one worker and injured several 
others. Initial exploration of the cave system by the workers 
identified some of the aforementioned stone structures and possible 
human remains; while attempting to contact their superiors, an 
instance of SCP-3667-1a violently emerged from the sinkhole and 
immolated the survivors. 


Foundation assets were scrambled from nearby Site-574 after 
intercepting dozens of police calls describing a winged humanoid 
creature; fires and collapsed buildings across the town of Mirny 
delayed the response time of Foundation personnel considerably. 
Ground troops proved ineffective in subduing or terminating the 
instance, and 17 MTF members were killed by immolation or falling 


debris before a Foundation helicopter was able to eliminate the 
threat. 


In the immediate aftermath, the town of Mirny was aerially 
amnesticized by Foundation operatives, and the extensive fire 
damage was attributed to a gas leak at the nearby Mirny Polytechnic 
Institute. Surviving workers and executives of the Alrosa mining 
company were amnesticized separately, and were led to believe that 
the Mirny mine had ceased production in 2004 and was now off- 
limits to the public. The existing surface-to-air missile system 
perimeter was established in anticipation of further SCP-3667-1a 
excursions, and SCP-3667 was classified as a Keter-class anomaly. 
To date, three further instances of SCP-3667-1a and one instance of 
SCP-3667-1f have exited the sinkhole; all have been swiftly 
terminated. 


Notable SCP-3667-1 Sub-Instances: 


This is a partial list only, emphasizing the most dangerous or 
noteworthy SCP-3667 species. For a complete list of sub-instances, 
see Document 3667-1: Complete List of Sub-Instances. 


SCP-3667-1a: Cynocephalic humanoid with large, bat-like wings, 
measuring 

approximately 3m in height. Entity is covered in short, coarse fur and 
continually exudes a flammable oil-like substance, which it is able to 
anomalously ignite and use in an offensive capacity. Captive entities 
display rudimentary cognitive ability, forming complex social 
structures and able to recognize recurring patterns in abstract 
shapes. 


SCP-3667-1f: Toad-like entity approximately 1m in height. 
Possesses no respiratory or digestive systems, and instead has a 
large, spike-filled cavity which instances have been observing using 
to transport SCP-3667-2 between variations of SCP-3667-3. 
Research is ongoing regarding how SCP-3667-1f performs 
metabolic functions without any apparent source of nutrients. 


SCP-3667-1m: Emaciated humanoid entity approximately 1.5m in 
height, with red-brown skin and oversized head. Entity displays 
human-level intelligence and speaks modern Russian, offering
