First of all, very cool, I like it a lot! And here's some random things I noticed - not all the tiles have a smooth transition with nothingness, might be a good idea to add a layer of stock "out of map" tiles around the map? It's not exactly what you'd call a horizon, but I think I prefer how it looks to an abrupt edge. Maybe as an option? Another thing is the whole demolisher situation. Looks like there's a rather wide band of land on the edge of Vulcanus where they don't spawn and the land is free. Especially with the hyperbolic projection. Probably something to do with the territories becoming too small. Not sure that's ideal. Could the algorithm be tweaked to limit the rate of squishing the territories? Or is it hardcoded with the terrain itself? The demolishers spawn just fine in the outer space, so there certainly might be a possibility. Also, maybe don't spawn them there? Even if the territory charting algorithm is fixed, I'm quite sure a script can just delete them immediately after generation.
