When I first played I used a fate point (stupid of me) You can get the schem for the key from one of the midgets P) in Wheel Clan
One of the Three Quest Dwarves on the residential/commercial level. Forget his name. There's the Toy Train Dwarf, then going north there's the Iron Clan Historian Dwarf, then there's the Buggy Stonecutter Clan Dwarf. You want the one in the middle, the Iron Clan Historian Dwarf. :grin: Veru convenient, having them all in a row like that.
Left.Norht Erick Obsidian, when you go to the left entrance through the main room (the one with that logo in the floor that seems a swastika :grin: ), you go to the left door and there you must find your way north there they're. And try to go during the morning if you want to do Tyrane IronHeart's qust, because otherwise he falls asleep for an eternity and you can't get the mission.
Re: Left.Norht I always can get the quest, & the EX points come when I talk to the brother. Tyrane will sleep so hard that you cannot report back.
