Bahamut

The Platinum Dragon

Bahamut, father of all dragons, is a pillar of wisdom, honor, and just leadership. He led the charge against his sister Tiamat during the Dawn War, and his followers helped bring down the Draconic Dominions. He's one of the gods most commonly invoked by paladins and leaders for guidance.
Bahamut takes the form of a massive, sinuous dragon with platinum scales that glisten even in darkness, a white mane of hair from his neck to his tail, eyes as blue as the summer sky, and wings that seem to span the entire horizon.

Divine Domains

Bahamut stands for justice, nobility, and honor. In the days of the Draconic Dominions, it was Bahamut's followers who worked to break the system from inside and out, so even humanoid races who used to be oppressed by dragonkind hold him in high regard.
He is also the patron and progenitor of all dragons; the chromatic dragons are descended from corrupted metallics, so even if they don't all acknowledge him, he's their father as well.

Tenets of Faith

Stand as a paragon of honor and justice.
Smite evil wherever it is found, yet show compassion to those who have strayed from the path of righteousness.
Defend the weak, bring freedom to the persecuted, and protect the ideals of justice and order.
