Stochastic Sparaogmos

From the introduction:

This is a system agnostic, modern day 'narrative first' scenario and would be ideal for a one-shot, or short series of games. Hopefully it will appeal to those new to role playing and to seasoned players alike. This scenario includes very distressing concepts. It touches upon sexual assault, cannibalism, interpersonal violence, violence against animals, vehicular accidents, and many others, so care should be taken to ensure the comfort level of players.
