Orbaz was apparently intended to lead a new order of death knights, the Host of Suffering, based out of Malykriss: The Vile Hold, a replacement for Acherus being built out of saronite. Seeking to derail the plans surrounding the new necropolis, the Knights of the Ebon Blade send out willing allies to disrupt saronite mining operations, destroy infrastructure, and slay the intended leaders of the new order, ending with Bloodbane himself in [80G5] The Fate of Bloodbane.
