Interesting, so with this information I can split the Koinen Hellenon up.

I've always wanted to do that. The Koinen Hellenon will only get Sparte and will turn into Lakedaemon. The Casse will turn into Athenai and Saba will turn into Rhodes.

Though I gues this would also need to have recruitment and units altered? I would want for the new Athenai and Rhodes factions to have exactly the same recruitment as the Koinen.

And what to do with those familly members, can I just change their name and bodyguard?
