Population Migration / Travel
Transhuman ships leave the Sol System. From Earth to Neptune, space ships travel out of their overpopulated system and toward the Alpha Avior System. They never make it to the Alpha Avior System, instead becoming lost and then blocked by Neo Terrans before they could reach it. Isolated in the Surro Aster Cluster and the various systems there, they begin to struggle to terraform the hostile systems there, finding a few golden worlds in the process.
