Speak with Tor'gan at Hammerfall in Arathi Highlands.
<Gor'mul tosses the amulet into the ground.>
Tor'gan sent you, didn't he? Pah! Why he feels some mercy towards me I would not understand. Mercy was denied me when I was not allowed to die with my Warchief in battle. A cruel blow fate has dealt me...
It did not work, I see. Nonetheless, I feel that showing him the power of the shamans will eventually return Gor'mul to his once proud self. The amulet's power was not great enough to show him our newfound power.
