Locate an Eye of Twilight within the Black Breach.
Cho'gall keeps track of his minions through these funny magical balls: "The Eyes of Twilight."
If I could get me hands on one of those, I bet we could use it to look in on Cho'gall and see what his creeps are up to. Get me one!
Search the Black Breach, east of here and just north of the river. Find me an Eye of Twilight, and do whatever you gotta do to bring it back here.
