Neutralizing the Nethermancers

Objectives
Kill 15 Sunfury Nethermancers and return to Nether-Stalker Oazul at Tuluman's Landing in the Netherstorm.
 * slain (15)

Description
The blood elves are fools! I'm glad that our trade relations with them have fallen apart. In all of my travels throughout the cosmos, I have never encountered beings so selfish. They continue to destroy the land around us with their manaforges, so let's see if we can put a dent in their operations across the bridge at Manaforge Ara. Their nethermancers channel energy to and from the blood gems to stabilize the flow of power. Go over there and wipe them out!

Reward
You will receive:

Completion
Anything that we can do to encourage them to stop what they're doing at these manaforges is a good thing. They certainly do not seem to be able to be reasoned with. And it seems clear to me that whatever their leaders have in mind, they are insane. As remuneration for your faithful service to the goals of the Consortium, I would like to offer you the coin of your realm if it does not offend you.

Gains
Upon completion of this quest you will gain:
 * 12650 XP (or at level 70)
 * 250 reputation with The Consortium
