"Ghoul" is also a shapeshifting demon that lives in the desert. The demon can take the form of an animal, especially a hyena. It lures unwary travellers into the [desert]]. It will then kill and eat them. The creature also preys on young children, robs graves, and eats the dead. Because of this habit the word "ghoul" is sometimes used to refer to an ordinary human such as a grave robber, or to anyone who likes the macabre.
