Seer Skahi:
May we be the light in the darkness of the coming winter.
The power of the ancient Orcs that you seek was created by the gods, but stolen by devils.
Find the Archon of Halisha inside the Four Sepulchers at the Human Imperial Tomb!
If entering is too difficult, go to the Shrine of the Loyal and fight Halisha's minions! He'll show up if you kill enough of them.
Defeat him and get the Resonance Amulet!
