Gruumsh is the unblinking god of destruction who unleashes the savage multitudes against outposts of civilization. He is worshiped by orcs and half-orcs and has dominated some of the other savage humanoids as well. Gruumsh is a brutal god who loathes Corellon Larethian but denies that he lost an eye to the First of the Seldarine.

Gruumsh tells his worshipers to do the following:

Though followers of Gruumsh maintain that their god was born with one eye, the elves assert that he lost an eye in combat with Corellon. The two divine powers fought countless times, and they remain the bitterest of enemies.
Gruumsh is a god of conquest, driving his savage multitudes to expand their power by whatever brutal means they wished. His shamans advise chiefs and warmongers to raid, kill, and conquer.
