If you hydrate too much while exploring, you might sink out of reality and find yourself in The Bathrooms. Here the air is muggy, filled with that half-smell of urinal cakes, and your breath comes back in echoes. No matter which stall you pick, you'll never feel alone.

This is where the real shit goes down.

The unwashed can't or won't recognize it, but we do. The forgotten spaces on the edge. The music of the pipes. The geometry twisted in knots by straining minds, the flowing matter in the deep darkness, the unplumbed depths of utter madness. You should have gone before you left.
