Enter Destiny’s March at the eastern side, and go to the eastern point of the diamond shaped hallways. Enter the room, and look for the Door of Hours leading to the SW hall. Continue clockwise around the diamond, opening Doors of Hours all the way, and you should hear the Ascetic’s Door open in the distance. This is past the western point of the diamond. The path leads to Hall of the Wroth God, where Hell Wyrm lies waiting.
