Demons are the servants of the Descendant Powers that want to take over Necromundus. Some have been Demons for long ages, others are fallen souls who have earned Necromundus as a first assignment. Demons are sexless beings (although for ease of communication or whatever temptation they may have going they can take on the characteristics of a specific gender, this is entirely a choice and one which can be altered). In their purest form, they are largely featureless beings of broadly humanoid shape, sporting very large wings and bearing an aura of crimson flame with a heavy scent of sulphur.
