Never heard of Deathwing? Well, I suppose you can be forgiven -- he's not currently in the game. However, Deathwing (also known as Neltharion), the former leader of the Black Dragonflight plays a big part in Warcraft lore. Despite the fact that he's not currently to be found in Azeroth, there's a lot of speculation as to where Deathwing might be. Grim Batol, where he was last seen? Returned to his long-empty lair? Or perhaps he's truly dead? Well, new information coming from the public test realms suggest that Deathwing may be back. BlizzPlanet is reporting that in the Black Temple, the NPC Lady Sinestra has a dialog referring to "the master" -- presumably Deathwing.
Still curious? Full text of the dialog after the jump.
