The SCP Foundation, the most important organization in this universe and the focus of the universe, is a secret organization entrusted by governments around the globe to contain and study anomalous individuals, entities, locations, objects, and phenomena operating outside the bounds of natural law (referred to as "SCP objects", or colloquially as "SCPs"). If left uncontained, the objects would pose a direct threat to human life and to humanity's perceptions of reality and normalcy. The existence of SCPs is withheld from the public to prevent mass panic and to allow human civilization to function normally. When an SCP is discovered, the SCP Foundation deploys agents to either collect and transport the SCP to a Foundation facility, or to contain it at its location of discovery if transport is not possible. Once SCPs are contained, they are studied by Foundation scientists. Test subjects acquired by the Foundation (referred to as D-class) are used to interact with dangerous SCPs due to the danger posed by those SCPs and the expendability of the D-class. The SCP Foundation maintains documentation for all of the SCPs in its custody, which can include or link to related reports and files. These documents describe the SCPs and include instructions for keeping them safely contained.
