Known as the Gnoll Lord and the Beast of Butchery, the demon lord Yeenoghu hungers for slaughter and senseless destruction. Gnolls are his mortal instruments, and he drives them to ever-greater atrocities in his name. Delighting in sorrow and hopelessness, the Gnoll Lord yearns to turn the world into a wasteland in which the last surviving gnolls tear each other apart for the right to feast upon the dead. Yeenoghu appears as a huge, scarred gnoll with a spiky crest of black spines, and eyes that burn with emerald flame. His armor is a patchwork of shields and breastplates claimed from fallen foes, and decorated by those foes' flayed skins. Yeenoghu can summon a triple flail he calls the Butcher, which he wields to deadly effect or wills to fly independently into battle as he tears foes apart with teeth and claws.
