Paebala quest NPC room is where I killed him. Keeping everything cleared in the vicinity of this room makes it pretty simple. Has some effect that turns NPCs around him into zombies. Will call any mobs around him for assistance. The Zalifur I fought spawned at LOC 170, -503. First room north down the east tunnel from Paebala quest room.
