In my current WIP, I have six countries. All of them will be referenced at some point or another throughout the story (either two or three books, yet undetermined), but only three will really be focused on. Arlynon is where the majority of the story takes place. It's the mountain region of the world, ruled by an Eir (basically a queen). The ruler of Arlynon is always female. To make the selection, five women of prominent stature (often political figures, or the equivalent to mayors) are chosen and lined up on a stage. A crow is then released, and he divinely intuits which of the five would be the best candidate for the job. The woman he lands on becomes the new Eir. Edelmira is the next country introduced. It's the desert region of the world, very similar to Morocco. Their country is ruled by either an Eir (female) or Eiron (male), but their process happens differently. They tend to stick with a royal family, though it has happened that someone outside the family has become ruler (making them the new royal family). When the Eir or Eiron gives birth, the baby is brought to the temple for a sort of baptism. There, their future is read by the Priestess, who determines what their most successful path in life will be. Oftentimes, the children are told their lives are best suited for work other than ruling. But when she finds one that she sees will be most successful as a ruler, she names that child heir to the throne, and he or she lives their life as such. To better explain, one of my characters is the son of the Eiron, the second born. But the third born was the one determined to be the best choice for Eiron, so he operates in conjunction with the current Eiron, his father, as the heir. When the current Eiron dies, his son, the third born, will take the throne. Make sense? Anyway. That's all I've planned for government. I haven't planned what to do about the third country they visit, but I know I'm going to need to. My characters will visit it frequently in the next book, so I need to have a grasp of how the country will operate. And I know I at least need to know the government styles of the other three countries, even if I barely even mention them. However, I don't know how I should do that. Should the remaining four countries also operate under an Eir or Eiron? Or should I come up with alternative government styles for them? It seems unrealistic to do the first, because why would all six countries operate the same way? But I honestly don't know. I don't read many fantasies of this nature, so I don't know how they handle governments of multiple countries. Any suggestions?
