Quest:Essence for the Engines

Objectives
Collect 7 Mana Wraith Essences and return them to Chief Engineer Trep at Area 52 in the Netherstorm.
 * Mana Wraith Essence (7)

Description
As the X-52's chief of engineering, I have to see to it that the nether-rocket's main engines are in tip-top shape. Unfortunately, I haven't built them yet. &lt;class&gt;, I'm in dire straits here! I have almost all of the parts. All that I'm missing is the engine core. Luckily for us, I think we can make use of the essence from the local mana wraiths to jump-start the engines. They can be found near most of the glowing trenches in the northern part of the island. Except for here in Area 52, of course.
