Thranconia

The major regions of the Realm are Dukedoms and Principalities. The two sorts are functionally identical, with the only difference is that Dukedoms are ruled by Dukes, and Principalities are ruled by Princes. Princes outrank Dukes in precedence, and are usually descendants of kings of nations that voluntarily yielded to The Realm at some point in history.

Dukes and Princes generally have wide latitude in running their fiefdoms, with only gross violation of The Law getting any sort of Royal reaction.
