Firefly/Serenity is a sci-fi series set hundreds of years in the future (2518). Anyone who has seen the series or the movie can skip the next few lines if they already know the background.
Mankind has fled the Earth-That-Was, for reasons that have become muddied during the centuries.
It took decades for mankind's exodus to find a new home, in a solar system with dozens of planets and hundreds of moons, each one terraformed for humanities convienience.
The planets closest to the sun were known as the Core worlds, and they formed an Alliance, to keep a unified peace. The worlds further out were known as the Rim worlds, and they did not have a unified government.
Eventually, the two factions came to blows over the Alliance's beliefs that everybody should be under their rule, better to live in safety.
This was the War for Unification.
The Rim worlds formed an Independent faction, nicknamed Browncoats after the long brown duster coats their soldiers usually wore. The two sides fought for five years, in space, air, land and sea alike.
Finally, at Serenity Valley on Hera, the Independents were outnumbered and surrendered. The common soldiers, serving in Serenity Valley refused to surrender, some continuing to fight for as long as seven weeks before being captured.
The Rim worlds had taken a heavy beating in the war, while the Core worlds remained untouched. Things settled down, the Rim worlds now nominally under the Alliance's rule, even if many people weren't happy about it.
What if the reason mankind fled the Earth-That-Was was the Great Ice (Great Freeze? I must confess that my knowledge of Sailor Moon is a little weak) that precluded the building of Crystal Tokyo?
The plot I have set out so far includes at leats one of the Senshi, most probably Saturn, turning rogue just as the Great Ice begins, believing it to be the wrong thing to do.
This Senshi would then travel with mankind into space, surviving longer that normally possible simply because she is a Senchi (and thus immortal: if Pluto can do it, why not the rest?).
She'd almost certainly support the Browncoats during the War of Unification, since the actions of the Alliance at least partially mirror those of the other Senshi.
Eventually, around 2518 (or just after the movie) the Senchi begin waking, to check up on Earth, to ensure everything is progressing properly only to find humanity has abandoned the planet entirely.
The missing Senshi, whose actions were not predicted, is still tied into the system maintaining their stasis, and thus is alerted to their awakening.
The story begins with the missing Senshi being alerted to the others awakening, most likely as a prolog.
Due to the exodus, the entire Black Moon Family arc is effectively ignored, as there's no-one around to populate Nemesis.
So, are there any questions or obvious plotholes (aside from the Black Moon Family arc issue) so far?
