From the introduction:
Their world is gone now, destroyed by their lone, unstable sun going supernova. They are the survivors, inhabitants of a massive colony ship carrying one million people, frozen and asleep, searching for a home. When the ship reaches a suitable star system, it awakens a small number of people to serve as crew and explore the planets in hope that one of them will prove a suitable home for the last remnants of their race.
This game should not be confused by the eponymous game of very similar setting also produced as a 24-hour RPG in 2011 by a different author.
