My point is that it's already confusing inasmuch as there's really nothing that properly demonstrates what you're defining as a nation, what you're defining as a region, and what you're defining as a city. Sana is a nation, but its boundaries are pretty much just as open as those of Ei Jei, which is a region. Instead, you should, like, shade countries as colors with a key, write regional names in all caps across the region they encompass, and then write city names with initial caps next to colored dots that match their national affiliations or something.
