"Oh, you're talking about the fairy tales. The Bible." Istredd didn't realize she was from a world like Wilhelm that had the same story. He doesn't know that it is a common story in other spheres, since it's not in his.

Istredd does, in fact, have those, but it's different since he's also not a million plus years old.
