The Shattered Islands: Part Two: Shells and Stones

There is a game called Stones and Shells. Two players shake a cup and place it face down upon the table. They peek underneath and count the amount of shells with the ridges up and the stones showing three lines. They both proclaim their points. They do not have to be honest.

Now, I play another game. The rules feel the same, but the stakes do not. There can only be one winner. And if I lose...

I die.
