Galaxiad: The Border

The Republic of Regina is either a small empire, or a very large pocket empire, centered on somewhere like Kinorb.

Its borders as of January 2023 are incorrect, but a good first stab.

One interesting problem is the Border.

The Wilderness is not barren; habitable worlds have survivor populations. Over the span of 800 years, technology floats up to what a world can maintain (whatever that is). They're not the same as they were in 1105, any more than England of AD1200 is the same as England of AD2000.

But there's plenty of room for problems. One problem is that the Republic looks successful, and to those on the outside, perhaps elitist or snobby or holier-than-thou. Maybe part of that is even true, sometimes, in some places, and maybe not. The point is that the border is not naturally secure. 

Hence the need for some sort of navy that does border control and manages what used to be called Good Wars.
