For the colonization area, I'm thinking about an extreme rimward system, beyond the Solomani Sphere, even beyond any cannon-mapped area (about one and half to two sectors to the rimward from the Confederacy border). The system would have been surveyed once or twice by the Confederacy; the original (now dead
) colony would have been a private attempt by one of the SolParty factions to flee unfavorable political conditions (read: being prosecuted) on a world where it was in minority. It was too far to be even under nominal SolConfed authority.
I'll generate the system using CT LBB6 once I'll have time.
