This quick start Castles & Crusades adventure is a fun one shot or convention piece.
Made with that idea in mind, it is a fast set up and linear (you are on a train).
With new creatures, traps this timed adventure lets you live in the moment, or if played poorly, forever as one of the train's inhabitants.
An adventure for 4 player characters of 3rd level of play (can be adjusted accordingly).
Also includes the following: 3 New Creatures, New Spells.
