I’m trying to wrap my brain around the expansion of domains…
Being an enterprising adventurer I’ve secured my little 6-mile hex domain in the borderlands. I call it This Land. It maxes out to 250 families so I begin securing adjacent 6-mile hexes, eventually securing an entire 24-mile hex. Hooray for the Domain of This Land, it is now at max size. To expand further I’m gonna need some henchmen. (This is per p. 129, Limits of Growth)
So I’ve got a full 24-mile hex. What Type of Realm am I. Looking at p. 229-230 I’m unclear if This Land is a Barony (it has no component parts which seems to match a Barony) or if it is a County (it takes up a full 24 mile hex but it has no Marches or Baronies within it).
The realm “types” or ranks are more of guidelines. You can call a village a kingdom and get yourself a crown, but most other nations will laugh at you for it. A king is a king because he has the too big an army for anyone to tell him he isn’t one (or he can trace his bloodline to a period when his family had such an army for long enough).
Do also note, that when you max out a Domain in the way you describe, you can upgrade from wild to borderlands and then from borderlands to civilized.
A single 24 Mile hex, comprising of 16x6Mile hexes, could potentially be a County, with 4 Marches and 20 Baronies (5 per March). Assuming average pop. density of 50, you’d have 5000 families with the largest settlement being a Village (Market Class VI)
The total population should be 5260, but with the default population density you’re looking at 5000 and therefore your Baronies will be smaller than default.
That’s based on Chapter 9s guide to generating realms, which I used to create a spreadsheet to calculate.
