in the tunnels there you will see a statue of a demon, you go into your invin and use the talismans one at a time but in a certain order and you will get a prize, do it in the wrong order and you are ganked 3/4 of your health. least that's what happened to me. as for the levers you activate all of them and you will see a brief clip of a treasure box being popped some where in the valley.. unfortunately I have no idea where it is but that's what they do. hope this helps in some way smile
