Bahamut

Many dragons speak of the ancient dragon-gods with nothing but reverence, but those that know of the legend of Bahamut cannot avoid the presence of corruption in draconic society of the past. Bahamut was said to be the most beautiful and powerful dragon alive in those days, but not even his opposition to the creation and summoning of the Comet could prevent the inevitable. Disgusted with his kindred, and planning for the devastation that would follow the coming of the Comet, Bahamut withdrew from the planet of IIo to come back when there would be need. The Ursa revere Bahamut as the Guardian of the Realm of Cosmos and Ruler of the Above.
