"There are some people talking to shades from other worlds," says Helen. "I don't hear that much about them, but they're there. I think maybe mortals are more affected by the afterlife than witches, or maybe it's just that the mortals I've met are usually younger than it is, and the witches sometimes aren't - I've known witches who forget once in a while about revenants and shade-dreams and things, and mortals don't do that so much."
