The orcs once lived as shamanic clans on the lush world of Draenor. Corrupted by Kil'jaeden, a demon lord of the Burning Legion, they invaded the world of Azeroth. Eventually able to free themselves from demonic influences, the orcs settled on Kalimdor, erecting their great capital Orgrimmar-from where they fight to find their place in the world they once came to conquer.
