Kill 7 Tidehunters, 7 Warriors, 7 Oracles and 7 Coastrunners and return to Captain Grayson at the Westfall Lighthouse.
You probably noticed all of the shipwrecks along the coast. The Great Sea is treacherous indeed. The coast of Westfall needs to be kept clear, so that if sailors find their way to our beaches, they are safe. The Murlocs are trouble though.
Kill 7 Tidehunters, 7 Warriors, 7 Oracles and 7 Coastrunners and I will see to it that you are rewarded.
