Ok, so the Voidyards, are screwed, but they are one jump from the Nomad Traders. I'm not sure what I'd call the aspect, but I'm definitely imagining Voidyard inhabitants selling/bartering ancient tech with the traders solely to get passage out of their crappy system.
I dunno I'm also imagining a lot of marrying/adopting into the Nomad Trader family's from the voidyarders. There's definitely going to be some diehards refusing to leave the decaying shipyards. But I really do feel like they are probably in the middle of a mass exodus, to any system that will have them. Actually guess I did figure out an aspect name. And I guess some of them are probably also heading to Oneida but that's a notable greater distance.
Aspect idea for Nyx-Omega Voidyards: Mass Exodus
Actually, considering that Vulcanthis is a major asteroid belt colony yet poor on nature, Nyx-Omega has all the ancient tech even if they're now regressed...
I'm going to suggest this for Nyx-Omega Voidyards:
Vassal-Uplifters of Vulcanthis
Basically, Vulcanthis was in trouble as a major asteroid mining colony which were not that great on tech despite having all the resources to pay for it. Which Oneida likely exploited to get a lot of resources for the tech they'd trade and get away with seeing as they were the technological hegemon of the cluster. Then Nyx-Omega Voidyards connected with Vulcanthis, desperate for any resources used to sustain a human population yet possessing a bounty of industry, technology and knowledge so long as it wasn't associated with life support in which they were only barely scraping by using jury-rigged and desperate replacement systems for the lost wonders of the past.
So a deal was struck. Vulcanthis offers up all it's resources in exchange for Nyx-Omega uplifting them, offering them the tech they needed to become independent and the remaining industrial capabilities of the Voidyards. So Vulcanthis ends up elevated to T2 whilst Nyx-Omega drops to T0 because they're getting everyone out they can until they fix or replace the life support systems. Which is rather a struggle because effort keeps needing to be diverted to fending off Oneida as they aren't happy about the fact they lost their hegemony over the cluster due to there existing a competitor now.
If the Voidyards can have their life support restored to anything like what they were originally... Well, there was never a problem maintaining or feeding the yards themselves. Just the workers. So once those workers can be maintained on site, the Vulcanthis-Nyx-Omega Coalition is going to go from the underdog competitor to Oneida to equaling or
exceeding them in everything but inhabitable worlds. So their one weak point will remain the fact they're tied to their agricultural stations.
EDIT: Gives a good reason for there to be struggle in the cluster as we have the Old Power of Oneida and the New Power of Vulcanthis clashing, with everyone knowing that what may well determine the results of the battle for hegemony being if that ticking count-down until Nyx-Omega can support the workers for the yards again ends before, or after Oneida seizes an unassailable advantage.
The hilarity of course being that if Vulcanthis-Nyx Omega could work together with Oneida, they have everything needed to rapidly solve those problems. Which would result in a technologically supreme, resource rich, ecologically abundant and industrially powerful hyperpower.
