I thought I would pitch this out to the general forum on the subject of domain building.
How would you model a domain being ruled by a council or a collective rather than a single strong fist. You could just say that one member of the council is the strong arm of the law (and has the levels to back it up) but what if you want a real group ruling an area?
Or how about a weak noble? There could be a strong regent as is historically frequent. But what if there were several factions to a domain that needed to come to a consensus for decisions?
I was thinking of replacing the single ruler with several characters with lower levels. But would that futz the math too much?
