Vereth the Cunning wants you to use the Lithe Stalker's Iron Chain to drag Scourge Bombs to 4 Lumbering Atrocities inside Malykriss.
4x Scourge Bomb gift delivered
We need to cause some disruption... anything to bring those death knights away from their leaders. If we lay waste to their minions below, I suspect they'll have to devote more attention to keeping a close eye on operations.
Abominations are easy prey - slow, predictable, and most importantly, stupid. Take advantage of their trust of the stalkers to drag them some of the scourge bombs scattered throughout the construction area. You'll be able light the bombs far before they figure out what's going on.
