I’ve been trying for a bit to do a domain rules conversion for a different system (true20) and I’ve pondered a few system agnostic changes that would probably require some rethinking.
Of these, the biggest/most daunting has been mostly trying to do away with provinces, because while they can provide some interesting info, they also feel limiting due to the basic “one ruler per province, borders never change” approach. Basically, I tend to use province levels as a marker of population (and have a different holding indicating land development), and I also tend to use tables where province levels indicates a population progression relatively similar to that of 3rd edition experience points (it used to be in the old accessories on the site, although I tend to use multiples of 4.000 or 6.000 instead of 2.000 (so I get actual medieval densities; 4.000 and I boost Anuirean and Brecht and some peripheral realm levels by 1, or 6.000 no modification).
Province holders would be both feudal landlords and sovereign princes; this means that a non-subinfeudated, undivided Avanil would be just 3 points shy of a level 14 province (assuming the trianglar sequence continues after level 10; on a sidenote, Medoere would be a level 6 province). It could also be split into 102 baronies. Both extremes would obviously be silly. I also use a quick rule of thumb from a rarely if ever applied french royal ordnance, so I use for minimal personal domains as level 1 for a baron (1 point), level 2 for a count (3 points, actually more like 4) and level 5 for a duke (15 points, actually more like 16), plus vassals if any.
Potential causes for splitting up holdings I can see would be
- Personal unions, keeping both realms separated
- Administrative divisions, provinces, shires, although I’m a bit iffy on this still.
- Distinguishing personal domain and the realm, as with the duchy of Lancaster and the kingdom of England.
- Exclaves, the province holding would have to be contiguous land. A potential source of nightmares, however, when you consider things like this, although it’s a relatively more modern phenomenon, and the split level 1s of Avanil do average about 80-90-ish square miles (Liechtenstein is only a tad smaller).
A province holder, even non-sovereign, would get the entire benefits of holding province levels, however the non-sovereign ones would be considered vassals, with obligations. A powerful vassal could eventually be powerful enough to resist militarily to attempts at removal, depending on the realm.
This would likely mess up with the level parity in some ways (say, your level 14 province can end up having 105 level 1 guilds), and needs further thought, but I’m not at playtest point yet (what with me only really gaming in the springs and summers anymore), and I figure a limit on the number of holdings might work out as well, although it could still leave a discrepancy between the total levels due to using this triangular numbers method to determine the link between population and province level. It also has the potential to monumentally mess up source if I keep it as is, but pooling source over an area might allow for less “squishy” sorcerers as well.
