Age of Kings
Lord of Dragons
Bahamut is depicted as a massive, long and sinuous dragon with silver-white scales and blue, catlike eyes. According to Complete Divine and Races of the Dragon, the exact color is hard to specify and may depend on Bahamut’s mood, ranging from sky-blue to frosty indigo.
About a quarter of the time, Bahamut wanders Oerth in the shape of a human or some other guise. He is said to have been encountered as a frail old hermit, with the seven great golden wyrms that accompany him disguised as seven canaries singing sweetly nearby.
