Azgoth


 * "Demon hunters... you dare attack the Doom Lord Azgoth in his own domain?"

The Doom Lord Azgoth was an annihilan who dwelled in a citadel on a demonic world, inhabited by felguards and felbats. Illidan Stormrage led his Illidari demon hunters in an attack upon the pit lord's domain, though during the ensuing battle Azgoth managed to strike Illidan with his flail. As he was about to finish the demon hunter, Kor'vas Bloodthorn leaped forward and blocked the blow with her warglaive. In response, the annihilan pushed her up against a wall and growled that she smelled "more demon than hunter" and that she would serve the Burning Legion well. Kor'vas simply replied "Never" as Illidan launched himself into the air and stabbed the pit lord in the back with the Twin Blades of Azzinoth. Much like Mannoroth had perished during the Third War, Azgoth instantly died and violently exploded in a burst of fel fire.

Speculation
If the world was located in the Twisting Nether or was extremely saturated with fel energy, Azgoth may have been killed for good.
