Prior to patch 1.4, this mount was purchasable from Lelanai in Darnassus. With the introduction of the patch, all level 60 mounts were given a new look, and were renamed with the prefix Swift. Those who had an old style level 60 mount could trade it in for a new one, but many opted to keep their old mounts because of their uniqueness.
