Korvasin: Run by a monarchy through bloodline, Korvasin used to be an empire that spanned a lot more land than it currently occupies. It has since stopped growing outward, but the economy is stable so the royals of Korvasin (the King/Queen of Crows, colloquially) are content to preside over their landlocked nation.
Rutan: Another monarchy through a bloodline, by virtue of being formed when a prince of Korvasin was cast out and fueled a rebellion against Korvasin. Its government is a blend of the monarchy and emissaries from the various groups throughout the vast desert.
Genfierz: Gen has a mixed Monarchy/Republic. The “royals” have always been figureheads and diplomats, and their duties reflect that. They are not offered as much decorum as the royals of Korvasin or Rutan, but they are respected as the voice of their nation’s leaders nonetheless. The sovereign and the heir-apparent of the royals of Genfierz are cursed to have tongues of living silver, though their “silver tongue” curse also grants them a natural charisma.
Meraev: Meraev’s main governance consists of several separate clans, each made up of multiple families, that govern their issues internally in most cases. Occasionally the clan heads will meet for matters of bigger importance but they usually keep to themselves. The cities in Meraev are where the non-Solian citizens tend to live, and the city governments cooperate with the nearby clans.
Faelands: The fae are governed, such as it is, by the Una and the Aubry.
