Quest:Summon Felsteed

Objective
Speak to Strahad Farsan in Ratchet.

Details
Warlock trainers in the major cities refer you to Strahad Farsan in Ratchet when you hit level 40. He is still residing in his tower overlooking Ratchet in the Barrens - perhaps you remember him? He will ask you to talk with him again and you will receive the ability (for free!) to summon a level 40 mount, the Felsteed.
