The hope of all the travelers is to find a hospitable new world that can welcome them to give birth to a new civilization. The Sideralis mission involves no return, a one-way journey to oblivion or to a new life. But the journey and landing are not without risk, and power struggles inflame tempers and threaten to destroy any dreams of being able to build a new life.
