The catacombs are vast and enormous and each square displays each possible direction that the player can go to, which gives an illusion of a possible 9 squares per square, so to map the place correctly, one would either need a very large sheet of graphing paper, or when mapping the level, map only the walls/directions that you cannot move so that you only use 1 square of graphing paper per move. I’m not sure how else to describe it to anyone reading this. It is just something that you will discover if you attempt to map the Catacombs yourself.
The entrance to level 2 of the catacombs are to the southeast of the level 1 catacomb entrance. Exact movement from entrance to level 2 stairs will be forthcoming.
