Ox's job prior to the Cataclysm was to send prospective Horde armorsmiths on a journey to find their calling. They first had to complete the quest for Aturk the Anvil. Ox would then give the blacksmith the quest  (Blacksmithing), which would send them on their journey to become an armorsmith.
Removed questsNote: These quests are no longer associated with this particular mob/NPC/item.
- Ox's appearance may be a reference to Babe the Big Blue Ox, a companion to Paul Bunyan the mythical lumberjack. (American Tall Tale folklore)
- Or maybe, it's a reference to Oxhorn, a machinima maker who plays a Tauren. One of his characters, Mortuus is already a NPC, so it is likely that the leader of the crew himself is somewhere in-game too...
- Patch 4.0.3a (2010-11-23): Quest removed.
