How many factions?

[Halcyel]

How many factions can the game support? I am new in the game and i like to add more factions but for what i saw there are only 4 i think, But i really like to add more mod factions to the game, so that in the end had about 6 or 7 faction in total.
Thank you for your time

I dunno I've had 40+ factions with a more factions mod before.
