Yeenoghu

The Dungeons & Dragons role-playing game, Yeenoghu is a demon prince, Demon Lord of gnolls. His personal weapon is his dreaded triple flail and he commands the obedience of ghouls and ghasts (mainly through his subjugation of the entity known as the King of Ghouls). As a demon lord, he rules his own layer of the Abyss, (The Seeping Woods), a salt-swept wasteland in which lurk gnolls, hyena-like creatures, and various carrion-eating undead. He himself lives in a mansion the size of a city pulled by thousands of slaves, which slowly makes its way across the layer. Yeenoghu is enemy to Baphomet, the demon lord of minotaurs.
