What happened to the kidnapped human babies at the end of Shinsekai Yori?
I would think that after the monster rats were defeated, and the ones that helped Squealer were executed, the people could have just gone back for the babies. It didn't take them that long to defeat Squealer and the akki that was Maria and Mamoru's child was from much earlier baby theft. That is what I think happened. A bit anti-climatic though.
