You walk along the left-hand passageway, passing tunnels from time to time, none of which looks like a particularly appealing route. You decide to see if you can reach the end of the passageway. You walk on and on, hour after hour. Then, in the distance, you see a figure approaching – a girl wearing blue jeans and a red sweater and carrying a backpack. She tells you that her name is Louisa and that she was exploring a cave and got lost. She does not know she is in the Cave of Time.
