Quest:Longtail is the Lynchpin

Objectives
Eliminate Draaca Longtail, the leader of the wyrmcultists in Wyrmskull Tunnel. Report back to Watcher Moonshade at the Wyrmskull Tunnel in the Blade's Edge Mountains once you have done so.
 * slain

Description
With the Blackwing wyrmcultists massing in the tunnel, we're hard pressed to deal with the situation. Quite frankly, they have the numbers. And while we've been able to take care of any of their people that get too close, the fact remains that if they attack in earnest, we're going to be overrun. The situation calls for someone to get through to the other end of the tunnel, and take out their leader, Draaca Longtail. Up for some fun?

Reward
You will receive:

Completion
With Draaca out of the picture, we should be able to take advantage of the situation. They'll be in-fighting over who should be in charge, and that will relieve some of the pressure. That is, unless the overseer mentioned in that note you gave me comes to take her place. Let's see if you can do something to make sure that never happens!

Gains
Upon completion of this quest you will gain:
 * 11650 XP (or at level 70)
 * 250 reputation with Cenarion Expedition
