Just so you know the alignments of the surrounding places:
Brevoy/Rostland: Chaotic Neutral
Nuemria: Chaotic Neutral
Pitax: Chaotic Neutral
Mivon: Chaotic Neutral
So....just putting it out there if you try and establish yourself as a bastion of law and principles with strict rules and borders etc. you might be in conflict with your neighbors.
Pretty much every surrounding nation is a "might makes right" kind of place. Nothing is really illegal, mob justice is the main form of justice, there aren't really customs and borders and large parts of the countryside are ruled by bandits and worse that kick up a bribe to the authorities.
They're not evil, just the River Kingdoms believe in freedom above all else. Everyone here pretty much came here to get away from rigid law and order and the River Kingdoms are notorious for heroes and mercenaries coming in and just carving up a new land only for it to collapse within a generation.
The River Kingdoms version of the "UN" is called the Outlaw Council and as refresher here are the River Freedoms:

Now to complicate things while you are getting the nod from Rostland (and apparently reluctantly from Brevoy) this area is still commonly considered part of the River Kingdoms so if you decide not to be a River Kingdom and distance yourself from the River Freedoms that might put you at odds with Mivon and Pitax...but might also put you closer to Brevoy and the Swordlords.
You will find that everything political from here on out is a tug of war between multiple different factions. Right now they can be boiled down into three main groups: Brevoy, Swordlords, and River Kingdoms.
However other factions that could be considered are Galt, Numeria, Taldor, Mendev, Kyonin and even the wild barbarians to the east in Iobaria.
