Agath

There is a being in the middle stratum of hell that is well known for its insatiable hunger. He is known to devour any being that manages to cross its path, so most devils try to keep their distance. This being, however, has the important task of keeping the trapped souls in check, ad he does so pretty viciously. His title of the Lord of Glutty isn't for show, for Ongroth has devoured so many creatures that his power grew considerably, and continues to do so with every soul that gets devoured for naively thinking they could escape Ongroth's watch.
