Corridors

Generate a map featuring underground, winding corridors, similar to those beneath a church. The corridors are narrow, run straight, and feature T-junctions; sometimes, they end in dead ends. The ceiling is vaulted and constructed of stone. The floor is partially made of weathered or decayed stone, and partially of earth. The entrance is on the right, and the exit is on the left side of the map. The walls are made of weathered stone and are covered with moss, while faint yellowish electric lamps from the early 20th century barely illuminate the surroundings.
