Harry and Hermione entered the elevator and the old man closed the old wooden grate behind them. The wall instantly reappeared, throwing everything into complete darkness. Hermione clung tight to Harry, but the darkness was so dense he couldn't even see her face ... though she was so close her breath tickled his ear. The lift rattled down what must have been at least a dozen floors beneath the ground, as various flashes of colour interspersed the gloom every now and then. It took a good few minutes before light re-appeared below them and the elevator came to a juddering halt.
