I'll find out where your gryphon is, but first you have to do something for me. There's a troll in Zul'Farrak, Nekrum Gutchewer, who possesses a medallion I would very much like to study. Bring me that Medallion and I'll use my powers to find Sharpbeak.
Zul'Farrak is across the ocean to the west, in the desert of Tanaris.
Ah, the medallion of Nekrum. It is rumored to have given the troll an unnatural long life, but at a cost. I hope to discover a way to reap the medallion's power while avoiding its... unpleasant side effects.
You have done me a service, <name>. I shall now uphold my end of our bargain.
