"You are hanging from the side wall of a shaft that leads down to a large cavern and the earth is shaking around you. When you started out the day you were on a grand adventure with a team of professionals looking for artifacts in a newly discovered cavern. About the time you reached the bottom, the ground began to shake and tremble. At first you thought to push forward thinking it was nothing. As the shaking got stronger you remembered that only one person could fit through the entrance of the shaft. Not wanting to get stuck in the collapsing cave you started scrambling for the climbing gear. While getting your gear ready you find your rope has been tangled by one of the explorers. This will be a cut throat climb to get out first or die.”
