[She certainly hadn't meant to make the girl sad. She tries to reassure her.]

I'm not sure what happened to the spirits that people once worshiped. [Branwen isn't sure if they were ever real at all, but she senses now is not the time to say that.] They might still exist. [It is possible.]

I have seen a spirit before, though it wasn't one that wanted worship. Many of the old beliefs were wiped out, but there are probably still people who remember, somewhere. It's impossible to know for sure. [She's not sure how to explain how closed off certain portions of the world are. She's never thought that there could be another world where she'd have to explain it.]
