Item #: SCP-ES-146
Object Class: Keter (Euclid tentative)
Special Containment Procedures: Knowledge about the anomaly that is currently affecting SCP-ES-146 is to remain accessible only to Level 4 Personnel and above. SCP-ES-146 must be contained in a Standard Humanoid Cell and will follow the Humanoid Maintenance Protocol. Due to its passive nature and possible side effects, it has been decided that neither SCP-ES-146 nor any instance of SCP-ES-146-1 is to be eliminated.
Given the inherently antimemetic nature of SCP-ES-146-1 instances, no additional containment procedures are necessary.
Description: SCP-ES-146-1 are multiple entities physically similar to a Senior Researcher of Site-313's Cognito-Hazard Departament, Reinaldo Casas (designated SCP-ES-146).
Currently, there is one SCP-ES-146-1 entity for each subject with knowledge of SCP-ES-146. SCP-ES-146-1 entities are part of a hive-mind, and maintain a non-reciprocal memory with SCP-ES-146. Although there are psychological and physical differences for each instance, they have all been described as if they were SCP-ES-146 (and are therefore indifferent to it).
Each SCP-ES-146-1 entity possesses antimemetic properties, as they can only be observed when SCP-ES-146 interacts with a subject. Upon SCP-ES-146 interacting with any subject, an instance of SCP-ES-146-1 affecting only this subject will replace it. Once the interaction is concluded, the SCP-ES-146-1 instance will return to its initial position.
It should be noted that, when interacting with multiple subjects, each instance of SCP-ES-146-1 will remain "overlapped" in the same space. As such, subjects will always perceive SCP-ES-146 according to their instance of SCP-ES-146-1.
The creation of new SCP-ES-146-1 instances occurs when a subject becomes aware of SCP-ES-146. If this is achieved through first-hand contact, then an unique instance of SCP-ES-146-1 will be created. When achieved through a third party, their instance of SCP-ES-146-1 will be shared between the first affected subject and its interlocutor.
It is known that a singular instance of SCP-ES-146-1 may change its personality and physiology through time, this being a direct effect of the growth of knowledge regarding SCP-ES-146.
Addendum-ES-146-1: Discovery Log
The existence of SCP-ES-146-1 was discovered two months after SCP-ES-146 was classified as E-Class personnel.
Through investigation with amnestic and memetic treatments, it was discovered that, in the office of Site-313's Cognito-Hazard Department, there were 12 SCP-ES-146-1 instances, each being next to a different researcher.
Every SCP-ES-146-1 entity was later captured and interviewed. All entities presented similar behaviour, consisting mainly of stress and anxiety.
Addendum-ES-146-2: Incident Log
On 25/10/2011, a containment breach was recorded at 03:13 a.m., when 113 SCP-ES-146-1 entities proceeded to kidnap SCP-ES-146 from his office in the Cognito-Hazard Department, gagging him and carrying it on their backs.
The local Containment Team was alerted to this breach and quickly proceeded to contain it. 8 minutes later, the previously named entities were recorded acessing their local Incineration Unit along SCP-ES-146. SCP-ES-146 was observed suffering from multiple bleeding puncture wounds, in an apparent state of agony. The SCP-ES-146-1 entities then proceeded to throw SCP-ES-146 into the incinerator, and retreated.
Once the Containment Team arrived at the Incineration Unit, no traces of this event were found.
At 6:26 a.m., SCP-ES-146 reappeared on its office without any recollection from the event.
No new incidents have been recorded.
