Dreygar
From MTG Salvation Wiki
Dreygar was a wizard of the Western Domains according to a Dominarian fable who overtook Aldon's Castle and ruled there as a tyrant. He used a force of nature to attack Aldon, but it was killed; nonetheless, Dreygar's horde of goblins seized the castle. He used a fallen angel to seduce Aldon, and forced him to ask his Serra angel to lead the fight against Dreygar; the Serra angel and fallen angel were both killed, and Dreygar was killed by Aldon.
