SCP Foundation

The SCP Foundation is a top-secret research agency that secretly over-watches the world and keeps it safe by containing and researching anomalous (and potentially dangerous) creatures and artifacts codenamed SCPs.

It originates from the creative fiction website with the same name, and appears in SCP - Containment Breach.

History
The SCP Foundation's history, due to the SCP universe's purposely ambiguous canon, is cloudy, but it is for certain it was formed in the late 19th century as an amalgamation of international governments, research agencies, and militaries with the intent to protect the world from things that shouldn't exist. After over a century of existence (an existence completely unknown to the public), the Foundation has contained over five thousand SCPs. A splinter organization called the Chaos Insurgency formed as a defection from the Foundation from one of its militaries and became a highly dangerous terrorist group at some point within the Foundation's history.

Members
The SCP Foundation is predominantly composed of highly intelligent researchers and scientists stationed within multiple top-secret research facilities called "sites" or "areas". They are protected by security staff as well as a private military known as the Mobile Task Forces, and perform experiments on SCPs they have imprisoned, using expendable death-row prisoners called Class-D's as test subjects. The Foundation is world-wide, with at least one covert facility in almost every country. It has at least hundreds of thousands of members, all religiously dedicated to their cause, and their numbers may stray into the millions. They are all managed and controlled by the O5 council, a small group of extremely enigmatic and powerful G-men.
