the left hallway
The dim light recedes and the music fades as you move slowly down the hallway. Very shortly, you can no longer see where you're going. Suddenly, instead of the perfectly smooth, glass-like floor you had gotten used to, you find a rough, rocky area. You put your hands out to keep from falling, and you find that the walls are rough as well. Not only that, but the rough walls curve around in front of you to form a dead end. Apparently, this wing is still under construction.
