Speculation
It is possible that the Tarren Mill location is an oversight as the Forsaken town is not known to have a gryphon roost. Considering this and the fact that Gryphon Master Talonaxe was the enemy, it could have been Aerie Peak. Alternatively, it could mean that the Wildhammer clan took control of Tarren Mill.
