Created by headmaster Altair Emris, X-3RT was the third generation of Warforged tests which were intended to retrieve valuable artifacts for the Emris Adventuring Guild discreetly. Sent to The Shadowfell after learning of Sarens deception, X-3RT managed to retrieve the Dawn Device after taking advantage of the chaos ensuing the Battle of the Four Armies. X-3RT was later dismantled in efforts to create the final version of the Warforged series, Emr1s.
