Seems cool. What are the frontier states like, what’s their relationship with the government?
The Frontier States are usually varying degrees of loose alliances and confederations of communities that happen to be kind of left aside by the Central Government. Their relation to the Govt varies. Vermont and NY are in a constant state of guerilla warfare, Pennsylvania regularly raids Westsylvania, Virginia dislikes Ohio veeeery much, but doesn't really care about them, North Carolina and Franklin actually have somewhat friendly relations, and then while nothing at the moment is happening between Georgia and South Georgia, Georgia has promised to level the separatist entity to the ground and hang all politicians supporting it.
Then there's some frontier states set in lands de jure under the Spanish and British, like Wabash, who's essentially almost part of Ohio, or Mississippi, who's really not much of a real thing, later historiographs would misportray it as a frontier state while really it was just a bunch of majority native settlements where most of the population was French, Spanish, British, Americans or other fur traders passing by and inhabiting the cheaper houses on this side of the river rather than cross it and pay full price to stay the week in like Saint-Louis.
Some then, like Bourbon actually recognise themselves as an autonomous county of Georgia, and West Florida is a guy and his followers who basically just created a state after seizing the local region.
