Nil

The Cosmic Plane of Nil was once called Shallamar, but was the first plane to be corrupted by the Taint. The great benevolent beings who ruled there - the Holy Emanations - were twisted and are now known as the Demon Lords of Nil. Frequently fighting among themselves, they rule over hordes of grotesque demonic creatures. The Demon Lord who has managed to keep the upper hand is Supreme Master Luciphage, whose exceedingly charming facade covers an utterly cold and calculating heart. His rule over the other Demon Lords of Nil is predicated not on his vast, dark powers, but rather his patient ruthlessness. The guardians of Nil are the Nihilists, who often emulate this style.
