Find the Mysterious Artifact being guarded by the Twilight's Hammer Idolaters in the northwest quadrant of the Searing Gorge.
Release them, [race]. Even after their bodies give out, the power of the Suntara forces them to complete their tasks.
The altar of Suntara is the key. Go northwest; in the hills above the cave... Twilight's Hammer guard a relic. Retrieve it and place it on the altar of Suntara.
