You have so many rurals that you aren't dependent on any single one.
And hell, we only have 2 rurals. We can manage 3 cities most of the times, and it has been ages since any city other than Port Nebel has revolted. You are close enough to actually trade with the massive farm realms that are to your north. Why don't you, if a few monsters is all it takes to threaten your food supply?
Don't go expecting pity from me because you find your realm doesn't have enough food.
The realm as a whole? No. Poryatown? Yes. And frankly I need Poryatown alive so I can squeeze its Duke for all its money to buy more troops to push back the abominations.
So Askileon is always in supply, Poryatown relies on Dantooine and Lupa Lapu.
However during Winter Askileon needs CT and Santoo as well.
IIRC, our cities are bigger than yours. The only reason you want Madina to get treatment instead of the whole continent is so you has food for the winter
