This episode originally aired as the Patreon bonus episode for January 2018. The original description follows:
Thanks to your continued support, I am... proud?... to bring you the latest bonus episode of Extraordinary League!
It all started with a simple question I posed to myself: what would happen if a bunch of League characters got on a train? The answer ended up involving a lot more improvisation, sky pirates, and ghosts than you might initially think. I'm so grateful to all of you for making this possible--I hope you have as much fun listening to to it as we had making it.
