Elemental Power Extraction

Objectives
Extract 5 Elemental Power for Chief Engineer Trep at Area 52 in the Netherstorm.
 * Elemental Power Extractor (Provided)
 * Elemental Power (5)

Description
Darn it, that didn't do it! Ok, I've got another idea! I had Xyrol whip up an elemental power extractor. I'm not certain exactly what this power will do, but I know that I can use it. The sundered rumblers and warp aberrations on the ledge of the Crumbling Wastes to the south have just what I need for the engines! The extractor will change the form of their power into something solid that you'll be able to gather up after you've defeated them.

Reward
You will also receive:

Progress
You have the power from those elementals yet? Oh, don't hurry or anything. It's just my life and career on the line.

Completion
That's more like it! Alright, now I think we're in business. Just let me dump this stuff into the thing-a-ma-jig here and I'm sure it'll spit out a fully functioning phase engine core. Oh, hey, I guess I ought to reward you for saving my neck! Hehe.

Gains
Upon completion of this quest you will gain:
 * 12000 XP (or at level 70)

Progression
