|The "Real" Chief Engineer Lorthander|
Mages are the only class that will be able to achieve an almost exact replication of his look due to his shoulder & robe color choice (from the mage tier 5 Tirisfal set). Other cloth wearing classes can pull off an incredibly similar look though with some alternative pieces which I've listed below. The alternative models are exactly the same, the difference is in the coloration. The non-mage armor pieces have a bit more orange, where the mage has more red.
