Item #: SCP-4006
Object Class: Thaumiel
Laconic Containment Procedures: Nothing really has to be done.
Laconic Description: SCP-4006 is a probabilistic anomaly affecting Massachusetts that caused a series of extremely unlikely events that led to the general public thinking that Massachusetts is inhabited by humans and possesses infrastructure, etc. In reality there is zero history of human civilization in the region.
The Foundation discovered this, and populated Massachusetts with Sites and personnel. By making the state "real", other humans started inhabiting it, eventually raising the question of whether it was neutralized, explained, or not.
Additional Context: The existence of a powerful anomaly like the non-existence of Massachusetts has led the O5 Council to discover the larger phenomenon controlling it, referred to as the Veil. It is a pervading force throughout the universe which ensures the maintenance of normalcy despite the widespread existence of SCPs and anomalous phenomenon.
SCP-4006 was an entry in the SCP-4000 contest, where it won 21st place.
