The One That Got Away

Description

Oi, you! Word travels quickly among our ranks. I heard about the work you did with the cultists around the remnants of the battle with Naxxramas.

Problem is, one of them cultists got away with a piece of the focusing crystal. Seems to still have some juice in it. Best guess we have is it's somewhere beneath Shadowvale. It's either raising 'em or making 'em stronger, and you don't want either one.

Find that crystal before this gets out of hand.
