The members of this mysterious organization are largely changelings and doppelgangers. While the Cabinet engages largely in pranks and schemes that seem to serve no purpose beyond sowing chaos and confusion, it is also behind countless crimes of identity theft, blackmail, and fraud. Many officials wonder if the seemingly unrelated or pointless misdemeanors aren’t part of a grand charade which acts as cover or enables the Cabinet’s greater crimes. The Tyrants of Sharn have ties to the Cabinet of Faces, but the true leaders of the Cabinet are shrouded in mystery.

For most people, mention of the Cabinet of Faces produces only amusement. Many don’t believe that the cabinet even exists, dismissing the idea of a secret cabal working to guide major governments and enterprises to some nefarious end. Yet the Cabinet of Faces is very real, with highly placed informers, spies, and assassins. Its goals and desires are perhaps the most closely held secret in the world.
The Cabinet of Faces is ruled by a group of six doppelgangers, each controlling six subordinate members (doppelgangers or changelings) called visages. A visage always deals with the same cabinet ruler and never knows the identity of any other. In turn, the thirty-six visages control a network of over a thousand affiliates, almost all of whom have no idea who ultimately employs them. Though the Cabinet of Faces took little part in the Last War, the war’s aftermath has seen the current cabinet rulers expanding their operations, marshaling their forces for some large action in the near future.
