The Country of Lucetania, the land in which they currently found themselves, was split into Five Dukedoms named; Caradja, Redmarch, Aeron, Tharivel and Solthia.
These consisted of various smaller counties, and even more cities, and to rule over each one there was a singular family, the head of which was known as the Duke, or Duchess in the cases that the leader was a woman.
How these families decided their leaders was ultimately up to them, after all, the King only cared that the individual in charge understood that they answered to him. If that was clear and understood, then how they were chosen was of little consequence to him. Especially when he could just execute those who were performing inadequately.
In the Duchy of Solthia, it was done purely by age. The eldest child ruled, until they died and then either their eldest child took over or, failing that, the sibling next in line.
