This looks really cool, at first I was getting a kind of Cowboy Bebop vibe, but with all the latin terms and the massive chronological scale I'm getting more of a Dune/E.Y.E. kind of far future vibe from it.

I'd enjoy either, but I'm still kind of confused on the scale you're going for. 

Who maintains and operates the hyper-rings? Do they house enormous populations themselves, or just skeleton maintenance crews? Would a maintainer have to be trained from birth to limit the chance of them defecting with trade secrets? I'm imagining they are something like navigator's from Dune. A clandestine, almost pseudo-religious organisation.

I have some possibly interesting ideas for a character. Don't want to spoil you, will DM you with more details once the ball gets rolling.
