The SCP foundation is a large place in the area 51 at America. It's a hidden place, a place where no one in the world knows its existence.
There are staff Researchers, D-class members which are death row prisoners in orange jumpsuits used as dummies, The guards which are really powerful soldiers, and Anomalies.
The SCP Foundation is ruled by the O5 Council, 12 very powerful people.
The Foundations job is to find anomalies across the world that arent supposed to be in the world, and contain them.
