So, I'm building a world for my ACKS campaign.
The starting empire-sized kingdom has a population density of 3,000 families per 24-mile hex, and claims about 800 hexes.
It's got a total population of about 2,400,000 families and a largest city/capitol with 24,000 families in it.

I feel like that without inland roads and faced with a really dense forest, the kingdom would claim the east mostly in name alone, which is in keeping with the "gradient of civilization/danger" concept introduced in the core rule book.
I have other kingdoms across a whole continent on my world map:
I'm assuming a global population of something like 40-50,000,000 families. Since all of the land on the continent is "claimed" by various civilized kingdoms or nations, it seems like I could apply the west-east gradient of civilization/urbanization to the whole continent.
I think I'll put something like Mt. Doom/Mordor in central or eastern Kalast, and fill it with the biggest, baddest, most evil monsters possible.
It'll be like a big factory of adventure and danger!
I already decided that Kalast should be "ruled" by dragons in a very laissez-faire fashion, and I might also decide that the nastier the monster, the nastier it tastes. Therefore the dragons prefer to snack on herd animals, then herdsmen, then beastmen, then other monstrosities, in roughly that order. That way the herdsmen have an incentive to keep sufficient tasty treats around for the dragons, and the dragons have an incentive to leave a bunch of monsters wandering around the place.
What do you guys think? Sound fun? Any ideas or suggestions?
(Oh, and as this is my first post: thanks, Alex. Your system is great, and inspired this world!)
