Confront 6 Sha-Touched Grunts.
If General Nazgrim sent you, then I trust you are capable of discretion.
When I arrived here, I found Garrosh... experimenting... with some ancient power that he found in the mountains to the north.

Unfortunately, so far the results have been quite the opposite.
Our troops are erupting into random violence. Go and interrogate them. If they threaten you, be prepared to defend yourself.
