In Muslim folklore, the ghoul is a demon of the desert that is able to assume the shape of an animal. It is an evil spirit that robs graves and feeds on the flesh of the dead or on young children. They inhabit lonely places, especially graveyards. They also lure travelers into the desert, sometimes beguiling those traveles by prostituting themselves, and then devouring them. The Arabic ghoul of the wasteland seems to be a personification of the terror of the desert.
