St. Bahamut

Saint Bahamut, the Platinum Paladin is a Filian saint and the patron saint of Dragonborn, dragons, paladins and justice. He was co-opted from the old belief in the platinum dragon Bahamut, the good god worshipped by Dragonborn and seekers after justice. Saint Bahamut is depicted alternately as a platinum dragon with a silver halo or as a Dragonborn paladin in platinum, armed with a blue shield bearing the symbol of the Church and a sword. He is also depicted accompanied by a swarm of canaries. Scenes of his fight with Tiamat are a common theme in religious art.

In the past, the monastic Order of the Jurors of Saint Bahamut, devoted to the principles of law and justice, were a prominent order serving justice in the name of the Emperor. They have since been in decline, leaving the paladins of the Order of the Platinum Knights of Saint Bahamut.

Hagiography
Sir Bahamut was a legendary knight, a Dragonborn of shining silver. He sought to do great deeds everywhere with his noble heart and strong arm, and wrong-doers feared his name. Hearing stories of the great demonic dragon Tiamat, Sir Bahamut vowed to destroy the sacrilegious beast, who became his nemesis. As his heart grew ever purer, so did his scales turn from silver to platinum. When he finally found the beast and had slain all her henchmen, he sent up a prayer to God for strength, and God turned him into a platinum dragon, and the two dragons fought. When remaining allies of the demonic dragon queen sought to trap Bahamut by closing the gates behind him, God sent him a flock of seven canaries who turned out to be seven celestial gold dragons, striking down his foes.
