Gavrock is a level 74 colossus quest giver who wants to help the stone giants with their efforts to fight Loken's forces. He is attempting to find a way to free the runed giants from their captivity to aid in the efforts of the stone giants. He is found in Ruins of Tethys just off the eastern coast of Grizzly Hills.
After asking Gavrock about Loken he says:
- Ah, yes. Loken is well known to me.
- It is he who commands the sons of iron in their ways against us.
- From his hiding place, he oversees their preparations for war with the goal of exterminating the stone giants!
