Bahamut was depicted as a massive dragon with mirrored platinum scales and shining eyes, the exact color of which was hard to specify and may have depended on Bahamut's mood.
His has made few appearances since the time of Xorvental, during which he often appeared as an old man, accompanied by seven gold great wyrms polymorphed into canaries.
The dogma of Bahamut is based on Justice, Nobility, Protection and Honor. He taught his followers to always uphold the highest ideals of honor and justice, to be constantly vigilant against evil and to oppose it from all fronts, and to protect the weak, liberate the oppressed and defend just order. He took a strong stance against Xorvental and the actions of dragons against mortals.
He also liked to reward strength of purpose and character in his followers. He has since retired from worldly afairs and now serves as a companion deity to Nuadun.
Bahamut disdained combat, usually asking goodly dragons or adventurers of great power to do his fighting for him. Despite this, he was easily capable of defending himself.Those who saw him fight claimed that he had two breath weapons, one a powerful cone of cold, the other a vapor that turned his enemies into gaseous forms. A third special attack was his roar, which disintegrated creatures or objects within 100 feet (30m). If facing off against more powerful creatures, this roar would still permanently deafen those who weren't turned to dust. On top of that he was a powerful warrior and was also reputed to know every arcane and divine spell.
