Cam scratches his head. "Yeah, but the Earths are also eerily similar in history. Except for oddities like the occasional Gotham, it turns out that all our plus-stuffs doesn't do much.

Daemons and witches and bears did some stuff, but you can still name major cities and books and historical figures, and Amariah will recognize the names, even if on her world John Calvin was a Pope and Protestantism started later with somebody else."
