Serenity Background

The "Yellow Submarine" Serenity RPG campaign was set during the same time as the TV show Firefly. The Unification Day bar fight that took place in the Refrigerated Refugees adventure is on the same day as the one Mal & Zoe have in "The Train Job". The campaign overlapped the TV show and the Serenity movie. The Miranda broadcast took place during the game, our player characters witnessed it along with the rest of the 'Verse. But the campaign continued after the movie's time frame and the players saw some of the effects of the Miranda broadcast.

Future campaigns may precede, overlap or follow the "Yellow Submarine" campaign and the events of the TV show and movie. This section is dedicated to information about the "modern day" setting of the 'Verse. Since there is a lot of unofficial and sometimes contradicting material on the internet about the background and layout of the 'Verse, I am trying to stay as true as I can to the actual material presented in the TV show and movie. The roleplaying game is my next source of information, then fan material.

I have run many one shot or linked adventures we call delves in the same setting and we had a short lived campaign, "Big Damn Medics" that followed the events of the "Yellow Submarine" campaign. We are starting a new campaign, "Lost Sheep", that will overlap the events in the previous campaign.

Jim's note- A lot, maybe most of this material is unofficial, it is us taking bits of the official material and trying to connect them and extrapolate what might have happened. A lot of my material in the War is an effort to provide a fuller time line and most of Emily's material about the Academy is more of the same.
