Yea, I'm approaching it slightly differently; this is more of a decay of what levels are reachable in certain classes by the greater population.We cribbed info from "Magical Medieval Society" and made an excell sheet for the larger kingdoms.
Ex: 10% of population was class level 1 equivalent, half of that was level 2, half level 3, etc.
Of the 10%, 6% were fighters, 2% rogues, 1% cleric, 1% mage.
Repeatedly halving population to determine class levels seemed a pretty common house rule back in the day.
I'm imagining there will plenty of high level NPCs who are something like wizard 10/rogue 4, because they've capped out on the progression they can reach for wizardry. And since this is ultimately about just explaining the setting, I don't need character facing rules to limit spell slots or anything like that. A 20th level sorcerer PC is just one of those one in a million potential people.
