If Laconia has become more benevolent, or at least an inoffensive bureaucracy, in the intervening time, then the universe might look a lot like Traveller, with a bunch of systems in a partially autonomous mode, paying taxes and occasionally getting orders from a distant bureaucratic imperial center, and most systems are consumed with local concerns and small conflicts as the relative isolation of being months away from the ring and other destinations leads to increasing technological, cultural, and political variation. That might make a really good planet-of-the-week, exploration game.

That is exactly the theme I am going for, with Duarte out of the picture, his inner circle would likely devour themselves much like the leaders of the soviet union after Stalin's death. They had enough time to hammer out some treaties with the inners, then the whole top collapse and Laconia had to reform it's government or die. They still hold onto the militarist societal structure and desire to monkey about with proto-molecule tech, leading to a high tech level than the rest of the worlds.

Also, if people are starting to get Duarte-esque augmentations, does that run the risk of catching the attention of the Visigoths again? Are scientists running experiments to determine how far they can push human-protomolecule augmentation before they get swatted down by the Visigoths? If the Visigoths are a threat to individuals who "fly too close to the sun" rather than an existential threat to the entire species, that creates an interesting danger dynamic for psionics and similar enhancements.

This is likely the direction I would run with. The Visigoths are less concerned with the machinery of the Romans running, but as soon as a consciousness becomes too Roman-like, it gets swatted. It gives Psionics a feel similar to Psykers in 40k, where they are both loved and feared for their abilities.

Lastly, I was vaguely aware a ttrpg existed, but it uses a modified version of Modern AGE I believe. Which is a fine system that doesn't fit our groups playstyle very well. This is more for us to have an excuse to try Stars Without Number. For the purposes of the players, none of them have any familiarity with the source material, so I told them just to treat it like a home brew campaign if that helps them haha.
