the catacombs is a strange dark and mysterious place

the entrance is a narrow path and on the edge of the grave area which is a total mess, in the first large room is dead bodies everywhere, either they just died in that room or who ever drags the bodies didnt taken them any deeper into the catacombs, small rooms with beds carved in the walls, a room that should have been hidden but its open, the bridge, all the traps and pinwheel boss location in a deep hole with water? very strange
