I am going to finnish my game tommorow.I am playing Julii and need just three provinces to finnish.

Before i start new game I would like to do next:

I am from Croatia but since I really suck at history in general I need your hlep. I would like to find out what faction (If any) the Croatia would belong in this game.Tryed to figure it out myself but since I have no idea what some of those factions (Pontus,Parthia,Dacia.....) are (partly coz of the english language) I got stuck at the begining.

So does any one know.....
