Sir, I think we've located him, he's in Orgrimmar. Wait.... he just teleported in Thunder Bluff, he must be a mage, and he's talking to Cairne Bloodhoof. APB: Be on the look out for a level 65 undead mage wanted for selling Vision Dust and Dream Dust in the Orgrimmar Auction House. Be advised he's speced in Frost. Sir, I think we should send our undercover Troll Hunter with Humanoid Tracking to catch him.
