This idea is just in an eggshell right now, but let's see if it might hatch. What I am thinking is making a set of separate kingdoms, all on a different piece of land. One is in the middle, and the only way they can trade and communicate is by ship. So each Kingdom has something that they specialize in of course, and maybe one king decides he wishes to rule all of them, so a lot of intrigue and diplomacy come into play. Etc, Etc, something or someone cuts of trade. Blah blah, but does the kingdom on separate lands sound okay? Or should I just make them duchies? Thanks for taking the time!
