Thanks. I've opened the blacksmith's room but apart from a unique weapon, I can't seem to do anything there. Can't see how to destroy the hatch to flood the citedal.... is there something I can do in here?
And after going to that chest and the blacksmiths, I still have two keys left. One is for the spider cage that I didn't block, the other I don't know. I think I picked it up in the lower citedal level where all the death knights patrol, in one of the storage rooms along their patrol route.
Plus I have another key that I picked up in the battlefield dungeon that I assume is useless.....
