Gruumsh
Gruumsh (pronounced: /gruːmʃ/ groomsh or: /grʌmʃ/ grumsh) was the patron god of the orc race and greater god of the orc pantheon. He was named He Who Never Sleeps for he was said to never tire, and symbolized with an ever-open eye to represent the orc belief that he watched over them all, judging the worth of each and every one of their kind. Gruumsh created the orcs and guided their destiny with the aid of his divine subordinates, ruling over orcish mortals and gods alike as their unquestioned patriarch. Long ago he swore that orcs would rule the world, and since then had driven his people to wage endless holy war in the name of his divine wrath.
Gruumsh normally appeared as a hulking, 10 feet (3 meters) tall orc covered in battle scars and clad in a black, gleaming suit of plate mail armor. His tough, gray hide was corded with muscle, and on his one-eyed face was a bear-like snout. In some incarnations he had only a right eye and an empty left eye socket, while in others he simply had one large, cycloptic eye that stared unwinking in the center of his forehead.
