The resulting grudge against the orc race encouraged an arakkoa, Grizzik, to serve as a tracker and guide for Danath Trollbane's forces during the Alliance's expedition to Draenor. This arakkoa, seemingly alone, led Trollbane's soldiers to Auchindoun, and aided in the battle.
Recently, however, some have broken away from Skettis - some to free themselves from Terokk's evil, and others deluded by power. The Skettis Exiles, taken in by the naaru A'dal, reside in the Lower City of Shattrath, where they battle against Terokk's forces.
