The only way out of this room is a narrow staircase downwards, and the only distinguishing mark on the floor is a solid white line going downwards. Entering, you are on one side of the line. The room is bare except a large bag full of plush balls, because even the dark magic schools wouldn't allow hard ones. The walls and floor are a grayish color that look like they wanted to be black but couldn't manage it. Unlike the other, grimy gym rooms, this one is kept in perfect condition.
