A winged, barley humanoid creature from hell. They are constantly trying to rule or destroy the earth, and use souls as currency. Whatever you do, don't shake hands with them, especially if there hand is cloaked in flames. But if you do, and your soul gets stolen, then... well, no one knows, actually. Presumably you just float around as a ghost or something. They tend to look formal and suave, except for some major thing, such as a bloodstained blade for a head or a face on it's hand. They are powerful magic users.
