Reeking Refuge

Objectives
Investigate what is disabling the coven's minions in Hocking's Plot.
 * Farm investigated

Description
Oh good, maybe you can make sense of this.

I was just carving through a swath of the coven's lackeys when I stumbled across this field. Something here has knocked these guys completely out of commission!

I can't seem to find the source, but maybe you'll have better luck. I'm more used to hitting things than investigating them.

Rewards
You will receive:
 * 1,650 XP
 * +75 reputation with Order of Embers
 * +75 reputation with Order of Embers

Completion
You don't look like you're in league with the coven, so what are you doin' in Corlain?
