Safety vs Birth
I recently noticed several posts (not threads) about population as a resource (e.g u need people to become soldiers) and that the main population growth came from survivors of the cataclysm not people born in your towns. If this is so wouldn't the "safety" of an area be important in determining the amount of people that want to live there. This could be an interesting mechanism for the overall gameplay. Example: your opponent has more of X (mana troops resources) but all of X is being spent on fighting the war not on the safety of his empire/kingdom. what if a smaller but safer kingdom siphoned population off of a more dangerous kingdom. Of course this could become overcomplicated if an enemy could lower your safety rating. I just thought that maybe increased "safety" could be a reward for quests or other random events.
1 more thought: how well known ur channeler is might also effect population growth. OMG channeler X killed the mighty dragon of doom lets go live in his kingdom.
just my 2 cents
