A large 3 story, burned out building, protected at every entrance by a ward that destroys anyone except for Exorcists. Regular survivors don't even know that the building exists due to a vision ward that hides the insides of the building from outside view, so they are never tempted to go inside.
1st and 2nd Orders are stationed here to oversee the Exorcists' missions and the 3rd and 7th Order's repairs and building.
