Necrosan's Soul is the stage in which the final battle between Necrosan and the player is. It can also be selected in a 2 player match by using the level select code. The stage looks like the inside of a castle with small tunnel holes with torches inside them. The floor is rocky and cuts off to nothing on the far right and left of the stage. The stage looks very incomplete compared to the other stages in the game. The stage is only on Old Urth and not on Neo Urth.
