Kill 15 Dust Stormers and 15 Desert Rumbers and then return to Duke Hydraxis in Azshara.
We, the elementals of water, wage war with those beings of the lesser elements. If you are truly our ally in this conflict, then show me your conviction!
Far to the south, in the desert land of Silithus, the servants of air and earth scurry in a corner of rock named the Crystal Vale. They protect items of power from smaller beings, mortals, and although I do not know why they do this, I wish to foil their efforts.
Go to the Crystal Vale in Silithus and defeat our enemies, then return to me.
