Ghoul

Ghouls are the eternal undead, sacrificing their souls for power, they live a cursed half life with no will of their own, doomed to wander the nether for all eternity. Some Ghouls, however, seem to have broken the unholy bond tieing them to their eternal torture and can make their own painful way through the world.
