Haunted Cosmos question

The fair folk was one of the most novel topics of this book. It's also one that Sauvé and Garrett left open-ended. So I wanted to create this discussion to pose the question: what is your personal belief about fairies after reading the book?

I don't know what to believe, but I do want to believe that God has appointed angels to preside over natural processes beyond the movement of the stars. It does seem like a step beyond what scripture says, but I would like to believe that all the old tails of the nymphs, dryads, djinn, and fairies are true.
