Gruumsh

The One Eye God
The patron diety of orcs, Gruumsh One Eye is a god of strength and destruction. Few can match him in fury and hate, for he embodies the power of the orc race. The divine symbol that

Might makes Right.

Orcs live and die by his commandments, and he commands the authority of an entire pantheon of hateful orc gods all dedicated to one thing, being the strongest gods in all the planes. To them all the other gods and goddesses will ether obey or be destroyed. Eternal war with the god Bane continues across the scattered plane of Acheron, hundreds of thousands of orc spirits fight against hundreds of thousands of soldier spirits in a never ending tide of battle. Gruumsh sees Bane as his rival, but his true enemies are the Elven and Dwarf gods and goddesses. It was Corellon Larethian who put out Gruumsh's eye, for that reason orcs kill elves above all others. They say the battle between Gruumsh and the gods of the other races began because Gruumsh and his people were denied a home, the elves claimed the woods, the dwarfs the mountains, the halflings and humans claimed the hills and grasslands. And for that they mocked him, foolish Gruumsh who has nowhere to go, his kind doesn't fit in anywhere. The rage that built from being looked down upon, the hate that weaker beings would think him the lesser, all of it boiled over into the One Eye God's fury. His destructive abilities are unrivaled, and in parallel he is unable to be destroyed.

For he is the symbol that Might makes Right.

And none are more mighty than he.
