Doom Lord Azgoth was an Annihilan who dwelled on an unnamed demonic world.
As part of his campaign of vengeance, Illidan Stormrage and his Demon Hunters stormed Azgoth's citadel in order to kill the demon. During the battle, Azgoth managed to slam Illidan with his flail. In response, Kor'vas Bloodthorn leaped forward and blocked Azgoth's attack. The Doom Lord pushed Kor'vas against the wall, turning his attention from Illidan who saw an opportunity and launched himself into the air, executing a maneuver that swiftly slew the demon.
