The Djinn is a powerful demon from Arabic legend, created by God from smokeless fire. This is the same being from whence the Western wish-granting Genie is derived. These spirits were created before humans, so it is really no surprise that the Djinn feel extremely resentful of the earth's usurpation by mankind. Usually invisible, the Djinn are powerful shapeshifters that are able to change into and manifest themselves multitude of forms. Each individual Djinn is different, and they vary greatly in terms of both power and temperament.
The Djinn are spirits of darkness, and are primarily nocturnal (sleeping during the day and venturing forth by night), haunting cemeteries, ancient ruins, and crossroads. However, some may be found in the vicinity of slaughterhouses, as the Djinn find fresh blood to be very appealing.
The Djinn is known to inhabit the thresholds of houses, and may strike out at those who disturb their rest. The attack causes disease, stroke, or paralysis. These ailments resist medical treatment, and usually only magic or shamanic healing is used. They desire and love heat, preferring to live in arid deserts for that very same reason. Not surprisingly, the Djinn despise the cold.
The Djinn, like most spirits, hate salt, but the spirit also fears iron and steel. The Djinn dislikes noisy and crowded places (although, on the contradictory other hand, the Djinn is a curious sort of spirit and will often take part in fairs, festivals, and other social events). Lastly, the Djinn enjoy telling stories, and can be lured out of hiding or pacified by exciting tales of suspense. However, despite their reputations, the Djinn have a code of honor, and even the most temperamental of these spirits will honor a promise or a vow. These spirits appreciate respectful behavior and will return any favors done for them.
