@Aristo If you're a Warhammer Fantasy fan, think of it this way.
Bania = Kislev+Sylvania
Kaelic Isle = Albion
But yes, I have more info. But I'd need specific questions.
That comparison definitely works for me!
You described Bania as having an elven queen: "Isabela." What's the government and racial makeup of the nation like? Does the throne have a strong centralized power, or is it more loose and regional? And how are the inhabitants on a technological level? Rivaling Andred or the Empire, or more antiquated? I'd like a clearer grasp on what their culture might be like.
I've got a good sense of the Kaelic people from your description. Seems that the Kaels, elves and dwarves get along fine; no doubt due to the adversaries they have in common. Are they still actively fighting Andred, or has the conflict come to a standstill? How loose or unified are the clans?
Both regions appeal to me, as I wanted to play a character who isn't as cosmopolitan, or "civilized" as someone from say, Andred, but still has a culture and society to call home. Both nations breed tough people, since they're filled with unsavory enemies and monsters. I can imagine several character concepts I could take from either; I think it's mostly coming down to aesthetics and cultural beliefs at this point.
Every Fiorentian nation has Ambrusian administrative offices, and garrisons of knightly orders that answer to the church. The religion is a deep-seated and pervasive one. That said, there may be a few maverick nobles that practice occultism in secret, or hedge witches that consort with magic in the deep of the woods. If a king should be branded a heretic, then he would be excommunicated, and the knights militant in his nation would likely maneuver to wrest control into direct Pontifical hands. Of course, the closer one is to the Pontificial States, the more prominent the Ambrusian influence will be.
