This is ugly but this is by request and I haven't time to clean it up. Perhaps later. Hope it helps.
Edit - NEGATIVE REP??
At least I took time to explore this and make the map. I originally posted it for a friend who requested help. Then I made it available to the community.
You gave me negative rep because you can't figure out the quest, even with my help? Do the work yourself then. Sorry I ever posted it.
