We came up with that term, "Chaos Insurgency", by the way. They co-opted it; they're good at co-opting things.

The Chaos Insurgency is a splinter group of the Foundation, created by a rogue cell that went A.W.O.L. with several highly useful SCPs in 1924. Since then, the Insurgency has become a major player on the world stage, using the SCPs that it obtains for its own personal benefit and to consolidate its global power base. The Insurgency not only deals in SCPs, but also in weapons running and intelligence gathering.

It makes use of dictator regimes in Third World countries, often using their populations in the same manner as the Foundation does D-Class personnel. Because of this, it helps to maintain the extreme poverty and war that is suffered by these countries, so that it can continue its radical experimentation, easy conscription of forces, and lucrative business deals with rebel factions.

Most of the SCPs possessed by the Insurgency are unknown, but of those that are known, the most notable are the "Staff of Hermes", an item capable of warping the physical and chemical properties of any matter it touches, and the "Bell of Entropy", an object that can cause a variety of destructive effects depending on where it is struck. Both of these SCPs were originally obtained at no small cost by the Foundation, and were stolen by the original founders of the Insurgency. The Insurgency also has a known association with SCP-355 and SCP-884.

The main base of operations of the Insurgency is unknown, as are its leaders. This organization is directly antagonistic to the Foundation, coming to clash over SCP items several times. Personnel are made to be aware of possible raids, terrorist attempts, and spies from the Insurgency, and to notify command about any strange behavior of fellow personnel.
