Erythnul (The Many) [Intermediate Power]:

Erythnul is the Power of capricious malice, envy, hatred, and fearful panic. His worshipers include many humanoids, for Erythnul smiles on fickle, wicked deeds from them them as much as from humans. Erythnul delights in the fear, rout, and terror of battlefields, and is himself depicted terrifyingly as a seven-foot brute, hairy and red-faced, with mad, staring green eyes. He can change from human to gnoll to bugbear to ogre to troll at will, and he carries a huge stone-headed mace. He is a summoner of creatures of battle, and if wounded, monsters spring from his blood.

Erythnul is worshiped by evil, embittered, cruel creatures. Services to him include playing of shrill and discordant reed instruments, the banging of gongs, and ritual drumming. Major rites include burnt offerings. Humanoids of the Bone March and the Pomarj include many devotees of Erythnul, as do evilly-inclined bands of bandits and brigands around the Flanaess.

Erythnul's Priests:

Erythnul's priests include many gnolls, bugbears, and ogres. There is no fixed hierarchy, and a junior may demonstrate his fitness to boss his fellows by dispatching an older priest (envy is a virtue, after all). The priests are bullies - hateful backstabbers and wanton killers - acting on evil impulse and revelling in bloodshed.
