Dual Rondo on the Sharne Train: A Drag Shergi Mystery

First Age, Year 960: It wasn't quite a vacation, but it wasn't work either. Drag Shergi ended up on a train going south through the country of Sharne. His intention was to try and find someone he might be related to. The west turned quite wild as bandits tried to take over the train. The train only goes one way though, so how do they plan to escape? How will the passengers escape? Drag has to think quickly when he becomes caught in the crossfire.
