I'm trying to start a short quest line that starts with ' Purging the White Hand', from the Orcs of Moria quest chain. Ultimately I am try to acquire the Onslaught of the Dwarves 3 piece set. Everything I've found leads me to Isolf as the quest NPC only he has nothing for me. How am I supposed to start this quest chain? Has there been a change to this that I have not found yet?
