Meet Tae'thelan Bloodwatcher at the entrance to the chamber where the Orb of Sciallax is held. Once inside, set the charges on the casing and recover the artifact.
We'll need to hurry before the nightborne realize what we're after.
I'm bringing the goblins along in case we run into any obstacles along the way.
I've marked the location of the entrance to the chamber the Orb resides in on your map.
Meet me there as soon as you're ready and we'll claim this artifact for our own.
