There are monsters aplenty, but no little devil or angel over people’s shoulders whispering what they should do at any point. Their decisions aren’t influenced by purely good or purely evil spirits. There might be spirits who try to influence characters, but they don’t belong to either of those two camps. Things are inherently more complicated than that, but it will take the characters in Fantastic America and Midwestern Magicians a while to figure out how any other reality might affect their world. There are enough people in both books who are monstrous enough without invoking beings demonic or angelic.
