Challenges in Revendreth (Necrolord)

Objectives
Complete the Destroy the Dominant World Quest, the Sanguine Depths Dungeon, or the Halls of Atonement Dungeon in Revendreth.
 * Defeat the powerful foes of Revendreth

Description
I've never really trusted the Venthyr of Revendreth. Maybe it's those long coats they wear, or maybe it's those pointy teeth, but something about them creeps me out.

Their leader, Denathrius, has sided with the Jailer against the rest of us, so I guess I was right.

I want you to find his most powerful allies in Revendreth and smash them to a bloody pulp. Send him a message from Maldraxxus.

Rewards
You will receive:
 * +2000 reputation with Court of Harvesters
 * Favor of the Court

Progress
You didn't let them bite you, right?

Completion
I have heard of your bloody exploits in Revendreth, and I am pleased. Did you bring me back any of their teeth? No? Well, maybe next time.
