This is the current list, though it is open to change
I remind you that this mod's focus is the meditteranian powers, particuarily Hellenic

The Jewish kingdom is rather difficult as it would have to be an emerging faction, which I am trying to avoid, and even as one would swiftly be swallowed by the seleucids or Ptolomatics as per game mechanics.

I am espeicaly willing to move around the barbarian factions, for example casse being replaced by a germanic faction, or the Celt Iberi replaced by the belgae ect ect. The rebel faction slots are also available for changes
