I already asked this in discord, but I was answered by someone on the team who's decision is not theirs. So I will ask Breadman directly:
We need to breed 30 human women. But we already bred Asha and Mammon. Will we be able to breed all of Lilith's sisters and the other supernatural characters? Because I don't mind breeding extra characters. I'm sure the dark seed can knock them up despite the not being human, we've seen the dark mark on Asha and Mammon, there's no way they're not pregnant. May I get a confirmation from you, Breadman?
