Wind Trader Zhareem has asked you to obtain Keli'dan's Feathered Stave. Deliver it to him in Shattrath's Lower City to collect the reward. This quest may only be completed on Heroic difficulty.
There is no accounting for taste. Take my most recent buyer for instance.
There is a blood orc within Hellfire Citadel known as Keli'dan the Breaker. He bears a most mundane stave; certainly nothing to take a second glance at. And yet, this is what my customer wishes.
Who am I to say no?
If you desire my compensation, you will find him and his stave within the Blood Furnace.
