Brimstone Express - a simple 3D6 system

Brimstone Express is a murder mystery adventure designed to be used with the 3D6 tabletop role-playing system that comes with the game. It can be easily adapted to other game systems as necessary. 

The brimstone is a large steam train headed to an unknown destination. Players arrive there and before long a murder occurs.

Will the players figure out the mystery before they go insane? 
Version 1.0 was designed for SpoopyJam 2022. Special thanks to RHO Interactive, Omaha Game Dev Association (OGDA), University of Nebraska @ Omaha, and all those responsible for the event. 

This is designed as a spooky spook kind of story. Some supernatural elements may occur. The point is to have fun telling a really fun murder mystery.
