Here’s the systems map with overlaid white circles showing how far you can get with top-end conventional FTL drive in six months, and a year respectively. Which is a good way of showing which clusters can hook back up and form pockets of civilisation. Learning the secret of the Reaper Drives would double the range or halve the time but really someone’s got to crack the secret of the relays to bring back full-on galactic civilisation.
Multi-System power blocs with the resources and personnel to re-ignite galactic society might emerge at:
1: Hawking Eta, Ninmah Cluster, Nimbus Cluster, Styx Theta, Caleston Rift.
2. Armstrong Nebula, Nubian Expanse.
3. Attican Beta, Hades Gamma, Artemis Tau
4. Local Cluster, Arcturus Stream.
5. Crescent Nebula, Eagle Nebula.
