The Sun Horse
Yelm, called Yu-Kargzant the Sun Horse by the Pure Horse People, is the Sun God who ruled over all during the Golden Age. He was betrayed by Rebel Gods and went to the Underworld, but returned with the Dawn to rule the world and give primacy to the Pure Horse People. The Pure Horse People ruled Peloria in the First Age, but were driven out of Peloria by Orlanth-worshipers from Dragon Pass. They came to Dragon Pass in the Third Age.
