The two gods descend together to uplift the mortal races.
Tiamat and Bahamut journey down to Malkor with dragonkind in order to better aid the mortal races. They arrive with gift of metal, the knowledge of dragons, and the strength and wisdom of gods. Not long after, the Church of the Dragons is created and Bahamut and Tiamat jointly rule Malkor, ushering a new age of prosperity for the world. Odari, Allfather of the Gods, disapproved; He sealed the two dragons from the realm of the gods, and they were thus stranded on Malkor, and forced to walk the land for eternity.
