Raeft

Raeft is a demon, one of the entities sent by the ephemeral evil forces which have designs on Necromundus. He periodically effects events within Necromundus in a malign fashion, but is generally benign to people in particular. The reason for his exile to Necromundus is not one of being an efficient and honorable foot soldier, but rather because he's a bit of a freak. Actually forged together, for whatever reason, from the fragments of several free-floating souls, the Demon has not thus far recovered any of his thoughts or memories from before his appearance in Necromundus.

Generally agreeable, but with a vicious side when it comes to his pride, property, and when insulted... the demon is a force for evil only in a functional, bureaucratic sense.
