Any records of activity are to be removed from all public 
knowledge. Witnesses and SCP-3713-A instances are to 
be amnesticized followed standard procedures. All D- 
Class are to be recovered immediately and the footage 
captured is to be extensively reviewed. Any records of 
activity are to be purged from all public knowledge as 
well as witnesses amnesticized to reduce suspicions. 


Description: SCP-3713 was a series of reality degradation events 
originating at 49.90° N, 97.14° W (Winnipeg, Canada) and ending at 
18.24° N, 66.04° W (Caguas, Puerto Rico) between 11/17/1898 and 
08/07/2015. These events only affected cities legally recognized by 
the US government and extended roughly 1 km outside of the cities' 
legal boundaries. Only a single city would be affected at a time. 


SCP-482: Mentally Mutating Straitjacket 


Item #: SCP-482 
Object Class: Euclid 


Special Containment Procedures: SCP-482 was recovered during 


an experiment being conducted by Dr. Bright at . After initial 
containment, SCP-482 was turned over to Dr. for 
documentation and analysis. Dr. Bright and Dr. are to be 


notified immediately should there be any changes to SCP-482 or 
any duplicates found. 


While it is not being tested, SCP-482 is to be stored in Containment 
Locker , located at Site- . Access to the locker is restricted to Level 
2 Personnel and above; such access (and all activities thereafter) 
are to be logged and recorded within 24 hours of completion. The 
maximum time limit for testing of SCP-482 is 1 hour after mutations 
manifest; all subjects who have reached or exceeded this point while 
in contact with SCP-482 are to be immediately terminated. Before 
autopsy and disposal SCP-482 is to be recovered first and 
separated from the subject’s body; localized thermal cleansing 
protocol is then to be performed on the body after autopsy and any 
biological samples or personnel deemed contaminated by the test 
subject. 


Description: SCP-482 is a black leather straitjacket of similar make 
tothe brand. Although the jacket seems to made for the Medium 
size, testing has shown that it can fit most body sizes; subjects with 
larger body types report, however, that they feel “compressed” or 
“suffocated” while wearing it. The words “Made in Tsiao-yan, China / 
Hand Wash Only / No Aserejena Powder” are present on the 
manufacturer’s tag in faded text. Neither the factory nor the item 
“Aserejena” exist on any known records. Finally, while there are no 
obvious signs of wear and tear on the item, there are several small 
cuts on the straps. Analysis has shown that these could not have 
been inflicted by anyone wearing SCP-482. Testing has shown that 


When an SCP-3713 event occurred, the population (defined as 
SCP-3713-A) began to behave as though they were members of a 
cast in a musical production, with the set and setting equivalent to 
the real life locality. The plot of each SCP-3713 Event changed 
between instances but tended to be roughly determined by events 
already set in motion before the occurrence of said event. For 
example, a major plot point during event SCP-3713-13 was the 
cancellation of an annual Christmas parade, which had been already 
planned for several weeks prior. A random group within the city, 
ranging from four to six individuals (defined as SCP-3713-A Prime), 
would be the focus of some sort of plot, often accompanied by a 
"supporting cast" consisting of an additional five to ten individuals. 


Any new objects or people entering the area of effect would slowly 
become subject to the anomaly's effects and be converted into a 
prop or actor. For objects this effect was almost instantaneous, while 
for people this process could take anywhere from 5 minutes to 6 
hours, depending on the person's proximity to SCP-3713-A Prime. 
This effect was stronger the more SCP-3713-A Prime individuals 
were gathered in one place. Following the conclusion of the event, 
roughly 99% of objects and all affected individuals would revert to 
normal. 


SCP-3713 events would follow a vague Prologue, Act I, 
Intermission, Act Il pattern, with a possible second Intermission and 
Act Ill. The Prologue was designated as the time in which 
SCP-3713's effects first show, beginning with the conversion of 
many objects into props (exact specifications difficult to measure 
and thus uncertain). Most members of SCP-3713-A would begin to 
lose intricacies of emotional expression and social interaction. 
Intermissions would be noted by all members of SCP-3713-A 
returning to their home (when applicable), and having between zero 
and eighteen members disappear and reappear at the beginning of 
the next Act. After all Acts are done, all members of SCP-3713-A 
would gather at the edge of SCP-3713's area of effect and bow. 


As soon as bows were finished, SCP-3713's effects would 
disappear. Members of SCP-3713-A would return to their homes 
and resume normal behaviors and routines the next day. Due to an 
as of yet unidentified antimemetic effect, all SCP-3713-A members 


would find nothing odd about the SCP-3713 event unless 
interrogated. SCP-3713-A were considered mundane once more 
after amnesticization.

Addendum-3713-2 | Further Details on Event SCP-3713-18 
Despite being a part of SCP-3713-A Prime, Camila Marquez AKA 
Pol-3713 never sang throughout the entirety of the SCP-3713 event 
and in several parts deviated significantly from what would have 
been the presumed story line of SCP-3713. Although initially calm 
during the events, presumably thinking that her friends were playing 
a prank or practicing during the first musical events, Pol-3713 
expressed fear and confusion in many of the events following these, 
especially musical events which involved large amounts of people. 
During the bulk of SCP-3713-18 members of SCP-3713-A ignored 
her behaviors and continued as if she was acting normally. 


Pol-3713 expressed intense confusion at the end of Act-lIl, where 
she was surrounded by singing members of SCP-3713-A, and then 
forced to follow the crowd prior to the ending of Act-Ill. Pol-3713 
broke from the crowd of SCP-3713-A and ran South from Caguas 
towards Guayama. As Pol-3713 approached the boundary of 
SCP-3713-18, the area of effect began to expand about 1 kilometer 
ahead of her. 


Upon reaching Guayama, Pol-3713 was met with a crowd of over 
1,000 SCP-3713-A instances. All instances were singing a song, the 
main chorus line being "Someone is SlackingS". Pol-3713 was 
picked up by the crowd, but escaped by breaking a window and 
climbing through it. After reaching the top of the three story building, 
Pol-3713 held their position for roughly an hour before SCP-3713-A 
members began to climb onto the roof through the ventilation 


systems. Pol-3713 was forced to back towards the edge of the 
building, at which point she turned around and jumped. 


Just before hitting the ground, Pol-3713 disappeared. Three hours 
after the disappearance of Pol-3713, all effects of SCP-3713 
ceased. Members of SCP-3713-A in Caguas were dehydrated and 
malnourished due to standing in one place for roughly 72 hours. 18 
lives were lost to various car crashes or bleeding out due to 
Pol-3713's escape efforts. A mass amnesticization and 
disinformation campaign was soon underway, and medical attention 
was given to injured individuals. 


Pol-3713 reappeared on the street, unconscious but alive, with 
several bruises on her head and large gashes of unknown origin on 
both her forearms. Pol-3713 was immediately taken under intensive 
care. After two weeks of recovery, Pol-3713 was returned to society 
and was assigned to a Foundation therapist. Pol-3713 has since 
shown cinematophobia, theatrophobia, heliophobia, post traumatic 
stress disorder (which is often triggered in tandem with the previous 
three fears), and a highly increased interest in photography and 
cinematography (despite her fear of it). For the sake of Pol-3713's 
mental health her mother, Cecelia Marquez, has been made 
somewhat aware of the events that transpired and the 
consequences of sharing information. No SCP-3713 events have 
occurred since, as of the time of writing (LAST UPDATED: 
08/09/2024). 


Addendum-3713-3 | Recovered Information from Pol-3713 
During Intensive Care 

After one week of recovery, Pol-3713 was able to speak. An 
interview was conducted immediately, and recorded below. 


> Interview w/ Pol-3713 


Interviewer: Dr. Robert Dorer 

Interviewee: Pol-3713, Camila Marquez 
Conducted: 08/08/2015 

Notes: Pol-3713 lies in a hospital bed in the 
middle of the room, with a chair to her right 
and the door to her left. Interview was 
conducted in Spanish, and translated to 


while immune to any damage due to body changes occurred by the 
subject, it can be damaged by external forces as normal for an 
object of this material. Further destructive testing on SCP-482 has 
been suspended due to the lack of viable duplicates. 


SCP-482 has two known effects, occurring in a linear fashion once 
the item is worn. These have been identified as Time Points Alpha 
and Beta; experiments have shown that while the effects of Time 
Point Alpha fade after loss of contact with SCP-482, those inflicted 
by Beta are permanent. 


Time Point Alpha refers to the initial stage of exposure to SCP-482. 
This exposure time lasts a varied period between 1 and 6 hours that 
a subject wears SCP-482. The item can be removed before Alpha 
elapses completely without ill effect. During this period, the subject 
feels “mentally better’; any mental afflictions that the subject 
possesses, regardless of degree or intensity, are negated 
completely. Any medication being taken by the subject has its 
effects completely negated as well. Foundation standard 
psychological tests return results consistent with a baseline normal, 
mentally stable individual. Upon separation of the subject and 
SCP-482, the mental illnesses return in full force, along with the side 
effects of any medication. Multiple sessions wearing SCP-482 have 
continued effect, though any time in the suit contributes to the 
overall cumulative time until the subject reaches Time Point Beta. 


Time Point Beta refers to the subsequent time period that passes if 
a subject is still wearing SCP-482 once Alpha lapses. During this 
period, the subject experiences physical mutation that seems to be 
determined by the nature of the subject’s mental disorder. Should 
the subject have multiple mental illnesses, the mutations will 
manifest according to their degree of strength. See Experiment Log 
SCP-482 for recorded physical mutations observed during testing.
