This mount is a quest reward from the quest . It can also be bought from Drake Dealer Hurlunk on Netherwing Ledge in Shadowmoon Valley for 200. You must be exalted with the faction Netherwing to obtain the quest and the right to purchase the mount.
After promising to fly you to the ends of Outland, the netherwing drake was eventually drawn to the blue skies of Azeroth as well.
