The Great Maw is the patron-deity of the Ogres that inhabit the Warhammer Fantasy universe, although the Great Maw is not entirely malevolent it is served by a species known for their brutality and insatible hunger: traits that the Great Maw seems to embody and champion.

Like many deities the Great Maw has no true form of its own but is represented by a huge gaping mouth, inhuman and circular, with numerous jagged teeth. Ogre culture revolves around eating, and as such the priest of the Great Maw are butchers, slaughtermasters, and cooks. It must be noted though that the food is entirely animal, with no vegetable matter whatsoever (making Ogres entirely carnivorous). Their religious holidays are supervised by the ogre butchers, and consist (mainly, and some times solely) of gigantic banquets and pit fights. Skrag the Slaughterer is the prophet of the Great Maw and thus can be considered one of its greatest champions.
