Given his clothing is similar to that of a lumberjack's he was likely one before his turning into a worgen, further supported by the fact that he wields an axe as a weapon.
With the coming of the Shattering, Fenros' model was updated to that of the new playable male worgen model. Unlike the other Nightbane worgen he is actually fully clothed and in non-tattered attire. He has also been given an axe as a weapon. It is likely that before his turning into a worgen, like many of the other unfortunate inhabitants of Duskwood, that he was in fact a lumberjack working in the area.
His model before 4.0.3a.
- Patch 4.0.3a (2010-11-23): Model updated. Level reduced from 32 to 22.
