Raveners were creatures found in southern Cthol Murgos, and eat the bodies of the dead, much akin to ghouls. In times of famine, pestilence or war the Raveners can go into a frenzy and attempt to eat the living as well as the dead. They are able to run for days, feeling nothing but all-consuming hunger. The only thing they fear is the sea, which they consider even hungrier than they.
They were described as grey, slobbering / slavering, scantily-clad or rag-clad ghouls or zombies who even ate their own kind that were hacked up. They obtained their clothes from digging up corpses from their graves.
