Would you survive?
You rush the old man, who is much faster than he looks. As you leap, he dodges and you slam head first into the hard granite walls of the cave. Blood flows from the gaping wound in your head. You try to move, but cannot. You then realise that your neck is broken. The old man reseats himself on the seemingly intangible desk. You die there, alone and unfulfilled. I would suggest making less impulsive decisions at this point in the journey.
