A labyrinthine complex of pipe organ rooms that play symphonies forever.
These rooms all have pipe organs that are constantly playing melodies and symphonies at varying volumes. The rooms vary in size and style, and each room has it's own symphony that it plays on an endless loop. Although stable, the environment does have a high risk for causing hearing loss and extreme paranoia. The longer one stays in this level, the higher the risk for losing one's sanity.
TIP: Wear headphones (any type will do). This helps alleviate the affects.
The pipe organs themselves appear to be the entities here, as they seem aware of wanderers. They tend to play louder once a wanderer enters a room, causing an increase in paranoia.
