The shadow that gripped Mordu and the blast wave...Mordu wasn't even in the plane. At least not the real one. The one Raven held in place that was killed by Jon. He was a fake arcane clone. He looked up and then floated up. "He doesn't have an artifact...he IS the artifact the magic he has now...it's in him." He shot a bolt at a demon flying up higher attempting to close the portals to stop the flow of demons.
