Ares the Oathbound in the Utgarde Catacombs wants you to recover the Sacred Artifact. This is a timed quest.
<Ares gasps for air as he tries to speak.>
I am an envoy of the Argent Crusade, charged with a sacred duty.
Our forces were decimated in the Plaguelands. By the light of dawn, the artifact was cleansed and made pure once more. So many perished in the wake of its redemption.
There is still a chance... still time.
The artifact was hurled into the den of the fallen, far below us. Guarded by the unmerciful dead.
<Ares' body glows with blinding light.>
Light. Will. Protect. You.
