The Unusual Suspects
This demon wears many faces, all branded with the same Glitch: a burning pentacle upon his forehead. Obviously it tends to wear hats.
A rebel and slightly insane, this demon believes that the God-Machine is behind everything. Even fallen Angels serve its purposes. So it broke its cipher and became free. And a bit crazy.
The Pentacle suffers from fugue states and sometimes forgets who he makes deals with.
