An army is pretty worthless if you can't feed them

Well, think about it. Agriculture is civilization. Farming enables cities, specialization, and large-scale cooperation. Without it, we're tribal hunter-gatherers.

The real silly face dragon should be Cyric, ever and always.

Cosmologically, I can even blame Cyric for the Dork Age that was 4th edition's sloppy campaign settings.

I mean, think about how many farmers have turned into level 20 John Fighterman. She's got an army of level 20 souls who can all attack 8 times in the first couple rounds each.

I mean yeah it makes sense. Agriculture is the foundation of sedentary civilizations; in a medieval world like FR the vast, vast majority of people would be farmers; and without food everything else just falls apart.
