Back in the Day I had a few characters running in different games, most where past the rebellion start date when it pooped up in JTAS, most of those campaigns died off but one transitioned over to MT, one character was General (Ret.) Duke Sabian Donagan Former Under-secretary of State for the Domain of Sol (five terms Army, one term Noble, two terms Diplomat), he was an Ethnic Solomani Imperial, politically he was a Solomani Reintergenerationist who favoured Semi-Autonomy.
He kind of started his own faction, he got together with his ex-wife IN JAG Sol and a buddy of his who was the COO of Rimstar Lines. he tried to forge an alliance between Craig & Margaret and the Anti-Luichian Rim Noble's, Bureaucrats and Senior Officers, He'd broker peaceful Annexation or Protectorate status by worlds facing down Solomani Fleets or defence for those worlds that wanted to stay 3I.
rest of the time My characters where neutralists or Norris from being Behind the Claw, then there was that Belter/Engineer who fell in with political moderate Sword Worlds Reunificationists, he left his Darrian Girlfriend to build a Robot Army for the cause, he was about done when GDW sprung Virus on us.
