Item #: SCP-4200
Object Class: Safe/Neutralized Archon
Laconic Containment Procedures: Keep a fence around SCP-4200-1 and wipe all records of SCP-4200 from everything. The three people affected have been amnesticized.
Monitor the historical timeline for alterations. Keep SCP-4200-2 fenced off and keep -A in a living chamber.
Laconic Description: SCP-4200 was originally described as an event during the Manhattan Project in which an experimental anomalous bomb was tested. Three researchers were caught in the blast and fused into an extradimensional space that represents consensus reality, referred to in the article's second iteration as SCP-4200-1.
From there, SCP-4200 members (referred to as SCP-4200-A, -B, and -C) have the ability to control the timeline, manipulating the public's thoughts, physical events, and so on. The Foundation removes -A, which inadvertently causes all of his alterations to the timeline to be undone. -A reflects on his time as a god but warns that -B and -C will inevitably try to cause a potentially dangerous major historical event.
Additional Context: SCP-4200 was an entry in the SCP-4000 Contest, where it won 18th place.
