Neltharaku, flying high above Netherwing Fields in Shadowmoon Valley, wants you to slay 15 Dragonmaw Orcs. Any Dragonmaw Orc in Dragonmaw Fortress will suffice.
I require time so that I may devise a plan to save my children and mate. You will buy me this time, mortal.
Venture into Dragonmaw Fortress, located on the eastern edge of the Netherwing Fields, and lay waste to all Dragonmaw orcs that you find. The ensuing chaos and confusion should have a considerable impact on their plans.
Be warned, some of my kin are too far gone - their minds corrupted by the Dragonmaw. For them, the only resolution is death. You have my permission to end their lives as well.
