After reading a novel about a Welsh witch named Rhiannon, Stevie Nicks not only wrote this song but she also altered her stage persona, taking to wearing black outfits with chiffon lace. "I see her as a good witch. Very positive," Nicks told Rolling Stone of the song's protagonist. "I sink into that whole trip when I'm onstage." Later, as people began to believe Nicks was a sorceress herself, she stopped wearing black for about three years. "I was freaked out that somebody would come and kidnap me because I was a witch," she said.
