Would that not be 4 nations?
Or was there no limit on the number?

I'm a big fan of writing internal conflict in my ICs, and no better way then having multiple smaller kingdoms vying for dominance in the region. Think ancient Greece, multiple kingdoms with their own internal conflicts, but united by culture and banning together when faced with an outside threat.
