Platinum Cadre

The Platinum Cadre was an order of dragonborn knights from Tymanther sworn to the service of Bahamut. The order was led by the paladin Patrin until his death. Because they worship a dragon god they were outcasts in Tymantheran society.

History
The order's priestess, Nala, claimed to be a priestess of Bahamut but was secretly a priestess of Tiamat. Because most dragonborn knew little about the gods of Toril, they were unable to distinguish the magic of Tiamat from that of Bahamut. Tiamat's power enabled the knights to use their breath weapons more often than most dragonborn. The order used its exceptional power to defeat the Ash giants who were attacking Tymanther even though other Tyamantheran troops were defeated by the giants.

Balasar exposed Nala as a Tiamatan and she fled to the Black Ash Plain and sought refuge with the green dragon Skuthosiin. Patrin was killed in a duel of honor with Medrash when he refused to acknowledge that Nala was really evil.
