Travel to the Gullet and speak with Zaela. Kill Torth.
Narkrall's drake Torth survived the failed attack on Thundermar, and now the creature is free from his former master.
Torth seeks vengeance against the Dragonmaw, and has already strafed Bloodgulch once. He will keep returning until we skewer him for good. It is time to put the Demon Chain to work.
Torth's old nest is a small cave in the hills west of here that we have turned into a small camp called "The Gullet."
Meet me at the Gullet and we will finish Torth off.
