I agree, that part where they elect a very far family member of the royal family to be PM or part of the Republic really made me feel confused. It seems that Krys is planning to return to his empire self later... you should be a little bit careful, his revolution was bloody but that doesn't mean Krys is not going to be back
You have to be empathic, Mars (Or whatever planet) is his home, seeing it being destroyed by terraforming is seriously sad. If it was your situation you would do the same.
But I am pretty sure we can arrange this peacefully with no need to sacrifice people or robots
I know this is a very complicated issue, since you have claimed it for centuries now and then other native species comes to claim all of it. But also destroying UM culture and landscape because of course "resources are a thing", so I am in favor of you leaving the planet but not in its entirety maybe TGR citizens can stay but of course in small zones.
You may have been there for centuries but UM has been there more time than you
