Item #: SCP-1533
Object Class: Euclid
Special Containment Procedures: The individuals that collectively comprise SCP-1533 are to be confined to a 10 x 10 x 10 meter cell in Site-██. Armed guard is to be posted outside of the containment chamber at all times. Should SCP-1533 attempt to escape, firearms are capable of subduing the entities only temporarily. Requests of a material nature - whether it be of books, film, music, or other media - are to be strictly denied and any personnel discovered smuggling paraphernalia into SCP-1533's cell will be removed from the holding facility and relocated per administrative orders. Under no circumstances are personnel allowed to fraternize with each other or the collective itself. All agents are to assume a neutral expression and allowed to only make short declarative statements in the presence of the holding cell. Any individualizing actions, social flourishes, or other interactions that go beyond the communication of simple directives will be added to SCP-1533's behavior pool and be utilized to facilitate an escape.
During the normally scheduled SCP-1533 event day, twelve (12) D-class exhibiting symptoms of autism spectrum disorders are to socialize with the collective in order to stunt SCP-1533's social growth. The desocializing of SCP-1533 must occur under the supervision of armed guards. Armed personnel are tasked with closely observing for any signs of the collective attempting to socialize the D-class for its own benefit, or any other anomalies. Operatives are prohibited from interacting with SCP-1533 in any way beyond making eye contact.
Description: SCP-1533 is the designation for an aggregate intelligence of unknown nature with command over ██ superficially human entities and their personalities. Instances of SCP-1533 only manifest as social gatherings of variable nature organized and attended by its comprising individuals. The SCP-1533 events occur at monthly intervals within a fifty (50) mile radius of the previous event's location, and are generally gatherings such as house parties or holiday mixers. However, SCP-1533 has not been known to organize events that rely on the attendees knowing each other prior to the gathering, such as family reunions or birthday parties.
The individuals that comprise SCP-1533 possess the ability to mimic the behaviors of human subjects they have interacted with in the past. Observed behaviors enter a collective 'database' at the disposal of SCP-1533 which are then distributed across the entities differently for each event. Each entity receives a personality schema consisting of a host of behaviors, skills, and personal attributes in order to perform a specific social role. The individuals need only to be in direct line of sight of an action to 'absorb' it, remaining sensitive to social cues even when apparently intoxicated. Specific examples of modifiable attributes include personal idiosyncrasies, inflection and cadence of voice, physical expertise in a sport or activity, oratory skill, the demeanor of an individual, and even sense of humor.
The ease by which SCP-1533 is able to model persuasive personalities is a sign of its growing social competency. The process is analogous to natural selection, in that there is a preference for favorable behaviors that will better endear it to future victims, and those that discomfort or otherwise "turn off" attendees are discarded. As a consequence, the individuals have progressed from exhibiting symptoms of low-grade autism spectrum disorder to becoming a highly alluring and dangerous group of individuals.
Outside of expanding its data pool, SCP-1533 exists only to exercise its power of manipulation over human beings. This can range from challenging a target's self-identity by persuading them to agree with obscene and untenable point of view, to more indirect methods that inflict emotional and physical harm on subjects. The collective has shown a preference for employing charismatic personalities to captivate human targets into threatening the integrity of close friendships and intimate relationships (see Personality List). The collective competes against itself for the emotional dominance of their guests, and those personalities with the most success have begun to exhibit some semblance of autonomy by brandishing tattoos and other symbols of status to denote their rank.
The beings exert such a profound effect on human beings that Foundation operatives routinely recover letters and personal belongings addressed to SCP-1533 sent by past guests to previous event sites. The entities have also attempted to bribe personnel by promising to secure them the love and adoration of specific persons in their lives, such as peers or romantic interests. SCP-1533's personalities have developed an aptitude for reading body language and facial expressions that currently exceeds Foundation understanding. Removing those personnel prone to the collective's manipulations has also proved troublesome, as it has only served to bolster SCP-1533's confidence in its own abilities. As of ██/██/████, operatives are to be assigned masks to wear so as to limit the social data SCP-1533 assimilates with every encounter.
