"Origin: Arabia. Man-eating demons that appear in graveyards. They carve human flesh and attack live humans, stealing bodies from their graves. The female form is a "ghouleh." Ghouls are believed to be a type of djinn. Invoking the name of Allah will drive them away."
"A man-eating demon of Arabian legend, often seen in graveyards. Its name derives from the Arabic word for "calamity." Ghouls are associated with the Arabian elementals called jinn. They are wild, vicious, and repulsive in appearance. Ghouls generally steal corpses from graveyards and eat them, but they will also attack and eat living humans. They sometimes assume the form of animals when attacking people, most often hyenas. Female ghouls are called "ghula" and use their alluring beauty to ensnare and eat human men. Calling upon the name of Allah will drive off a ghoul. This is because Allah created the jinn, and ghouls do not dare oppose the God that created them."
