I actually noticed something thanks to Kiyoko, but the game does as little as possible to keep track of anything about the champion. Kiyoko can get knocked up even if you're more barren than a desert, so it's impossible not to have kids. However, it's not like any NPC fights you have allow you to check if you got someone pregnant either. One thing LT made sure of was that everyone has the exact same fertility, barring special exceptions like certain races and corruption level (oh yeah, corruption actually does change you, I wonder if CoC2 will ever add that). So corruption doesn't do shit, fertility doesn't seem to mean anything, is there a reason these systems need to exist if pregnancy is just scripted? At least in the other game I can knock up anyone who doesn't have a straight 0 to fertility.
