The Eternal Dragon

You have made a pact with the eternal dragon from the fire plane of existence, a being whose aims are evil, even if you strive against those aims. Such a being desires the corruption or domination of all things, ultimately including you. Eternal Dragons can be a red, gold, or brass for they have been corrupted by power. While in a pact with this patron you receive powers of flame and healing. Some may be able to even summon their patron to the field to support them in their time of need. While others can utilize their spell book to the absolute maximum and, devastate the battlefield with flames. While some may prefer the barbaric approach and cut down their enemies while cursing them in their stead.
