Gruumsh

Gruumsh, who is envisioned with one eye by all who name him a god, is a deity mainly worshipped by orcs and orogs.

Worshippers
Orc war priests wear a patch over one eye to symbolize their worship of the orc deity. They also dress in dark red vestments, armored with war helms and black plate mail. Gruumsh's sacred animal is the giant rat and his holy day is the new moon and he is worshipped in orcish lairs where blood is sacrificed to him monthly.

Relationships
Gruumsh once had an alliance with the conniving drow goddess Araushnee to bring down the gods of the elves once and for all. His plan failed, despite a divine force brought against the elven gods consisting of the Seldarine's enemies in all the goblinoid and elf-hating pantheons and Araushnee was transformed into Lolth. The two deities have been great foes ever since, though Gruumsh's alliance with another assisting deity, Malar, has not been so badly corrupted.

History
In a past time, Gruumsh had two eyes but he lost one in a fight with the chief elven god Corellon Larethian. Gruumsh meant to paralyze Corellon with his magical spear; this attack failed and initiated an epic battle. During the course of this battle Gruumsh injured Corellon and, according to legend, from the blood shed the elven people were created. Corellon ended the fight by putting out Gruumsh's left eye, which is how Gruumsh earned his moniker One-Eye. Some orcish clerics deny this tale, dismissing it as elven propaganda while claiming that Gruumsh always had one eye.
