Slay Watchkeeper Gargolmar, Omor the Unscarred and the drake, Nazan. Return Gargolmar's Hand, Omor's Hoof and Nazan's Head to Caza'rez at Thrallmar in Hellfire Peninsula.
Quick, there isn't much time. Thrallmar's existence balances on the razor's edge!
We're caught between Hellfire Citadel in the west and the Burning Legion to the east. With the Legion's attention turned toward the Dark Portal we must take this opportunity to strike at the fel orcs of Hellfire Citadel. The key to this is to first break through their ramparts!
Go there, slay their leaders, and then bring back proof to Caza'rez across the room from me!
