I'm still around, just waiting on AB's history before I start working some more on my NS.
You shouldn't have to wait on my slow ass, so jhere's the outline I have;
-After the dreamer's regime falls, in the vacuum a coalition of miners rise up and go about taking control by force in some areas. These miners are Astronomicist. For a few decades they spend their time consolidating, but than they begin exploring the rest of luhman [by about 2545 they should make contact with your guys; initial contact should be fine since they'd use the shared history of previous persecution to try making a short lived "brotherhood" of sorts that due to conflicting ideas of how to run things doesn't last]. [For one, my guys would give support to astronomicists within the new dawn republic. My guys when it comes to other sects of astronomicists are surprisingly tolerant, although expect long and protracted debating that goes in circles].
The Kaishis Communion is made official around 2540 as a faction that bases itself on the barren world close to the brown dwarves multiple space stations have to hug closely to in order get energy.
Later my guys go about exploring further parts of the luhman system, where they'd likely encounter any third faction basing itself in the outer reaches of the system. As well the expansion of the KC may run into conflict with expansion of the NDR which might cause a several battles in the 150 years between contact and now, but due to the relatively smaller spaceship fleets maintained [being it seems both our factions are quality > quantity] no major war breaks out. However relations to 2700 despite tensions relating to who owns what part of the asteroid belt have been relatively stable with trade still going on until more recent as factions in the NDR want to have even the parts of Yumogesi that hae been claimed by the KC for training purposes.
However, that is a joke compared to the real diplomatic tension that is the warp gate.
In the late 2500's researchers in the KC began to figure out how to use exotic matter in FAL drives to make a worm hole. This lead to a technological revolution of sorts that accumulated in the year 2677 with the creation of the warp gate in sol. The warp gate was placed in the outer parts of the solar system and the luhman system for security purposes [it turned out there was no way to shut off the worm hole outside of waiting for it to deteriorate].
The KC however due to creating the gate way has, despite making a program between "all factions of luhman" put lots of restrictions on other factions only allowing one ship every 4 years while allowing one ship every 2 years for their own faction. Initially they had it at one ship every 10 years for others until they got negotiated down to 4 years by other factions.
This is a outline i'll admit, but it should be enough info for you to use to go into the post-dreamer luhmani history.
