The ghoul is a desert-dwelling, shapeshifting demon that can assume the guise of an animal, especially a hyena. It lures unwary travellers into the desert wastes to slay and devour them. The creature also preys on young children, robs graves, drinks blood, and eats the dead taking on the form of the one they previously ate. Because of the latter habit, the word ghoul is sometimes used to refer to an ordinary human such as a grave robber, or to anyone who delights in the macabre.
