Ghouls ares a type of demonic spirit found in Arabic mythology and folklore but has also become a word used to describe a number of unrelated undead monsters - the ghoul was believed to haunt graveyards and dig up graves so as to feast on the dead bodies: this trait has remained an important part of the legend of ghouls and in most translations a ghoul is depicted as cannibalistic and degenerated, one of the oldest surviving texts that relates to ghouls in A Thousand and One Arabian Nights but they have appeared in countless other legends and folklore around the world.
