Bahamut, the King of the Good Dragons, is the only known Platinum Dragon in existence. He is the leader of good dragonkind (metallic dragons), and is very stern and disapproving of evil. He accepts no excuses for foul deeds. On the other hand, he is very compassionate, and has boundless empathy for the weak and downtrodden. He urges his followers to promote good, but to let people fight their own battles when they can, providing healing, information, or temporary safe refuge rather than fighting alongside those who can fight for themselves.
For a dragon, Bahamut is neither vain nor greedy. He values wisdom, knowledge, prophecies, and song. He is revered by all good dragons, but gold, silver, and brass dragons hold him in particularly high regard. Priests of Bahamut may be dragons, half-dragons, or other beings. They strive to constantly, yet subtly, act on behalf of good. They oppose evil, but their first mandate is to ensure they do no harm in the process.
