Tor and Armadons stage is Tor's Crystal Place. The stage looks like Armadons stage from the first game. On the left the living area for the humans is still their however it has changed from a hole in a cave to an actual building structure of sorts. The entire place including cave supports have crystals all over (Where the name comes from) and their seems to be a light in the background probably the opening of the cave to the stage.
