"Yes I am."
Soon we were back at the exterior of Death Mountain and new areas were open to me now, a tavern, an inn, and a bath house, full of new potential followers but I still couldn't open the very first door of the quest due to not having the first key. Eventually I gave up and looked on the map where I should go next, when I happened to hover over "Nerelia House", where I got the horse Red Shadow. Oh! That's where you live.
Deciding that someone should survive this tale I opted to take Nerelia home and released her from my service. She said I could keep the horse though. Also in her basement I found key #1. LOL! I raced back to Death Mountain and opened the mysterious chamber only to find a smallish zone with some left over undead and the next key which opened that gate I had jumped over previously.
No matter, Death Mountain was now cleared!
