Exodus: Archimedes' machines

Humanity has found a new home among the stars. But freedom has no place there.

The Exodus began forty thousand years ago. Humanity built a fleet of ark ships and fled a dying Earth to seek a new home among the stars. Travelling at near light speed, these ships crossed vast distances over several generations. Many were lost forever in the cosmic void, but one fleet discovered habitable worlds far away in the Centauri cluster.
Other arks then set out on the long journey to this new world. Thousands of years later, Centauri is thriving, and the first settlers have evolved into advanced beings known as Celestials. They have split into five Dominions, the most powerful of which is the Crown – an alliance of five houses ruling vast areas of the cluster. However, upon waking from hibernation, the newcomers from the arks find that the Celestials rule with a cruel and ruthless hand.
One of those refusing to accept this oppression is Finn, born on a world governed by the Crown Dominion. He has never known Earth, but he dreams of the possibilities hidden in the universe beyond his home.
He becomes a Pilgrim, joining a group determined to find new opportunities and a future for humanity.
