Gruumsh

In the Dungeons & Dragons role-playing game, Gruumsh, also known as Gruumsh One-Eye, is the patron deity of orcs, who regard him as the god of Conquest, Survival, Strength, and Territory. He is also considered a member of the default D&D pantheon of deities. His symbol is an unblinking eye, or (in the Forgotten Realms campaign setting) his missing unwinking eye.
