Trivia about Grand Duchies
The first Grand Duchy ever was Barad Duin in Central Texas, the first kingdom style group after the Burning Lands. After a history too long to relate here, the people of Barad Duin formed their own game, called HFS.
Glen on Grand Duchies in Neverwinter
In Neverwinter, a "Grand Duchy" (we don't have 'Principalities") is a group that is sufficiently large to be it's own Kingdom but that is within the borders of Neverwinter (we're a floating crown). A Grand Duchy can give awards up to 8th (9th and 10th are the province of the Kingdom). A Grand Duchy also pays 30% of their dues in taxes to the Kingdom, versus 20% for a Duchy. Finally, you get better titles for leaving office. Grand Duke gets Count, Chancellor gets Baron, Regent gets Baronet, and Champion gets Lord. All in all, it's mainly done because the people in power want cooler titles and bragging rights, in my opinion. I wish we were only a Duchy, so I could keep more of our money.
Phocion on Grand Duchies in Dragonspine
Grand duchies/principalities can do everything but knight people, qualify them for Masterhood, and give them masterhood. 10th level orders of anything, knighting, and masterhoods are the sole province of a Kingdom. You can have (and are encouraged to collect) sub-lands, as proof that you may one day be a viable kingdom. At least, thats how it is down here in DS.
