I was going to sleep one night, but I like to read before bed, so I was reading "The Name of the Wind" by Patrick Rothfuss. In this book, the main character experiences quite a few threats. This got me thinking about one of my favorite series of books when I was a kid: The Chronicles of Prydain. In one of these books, I forget which, an evil wizard makes a threat to the characters. He/she threatens to turn one of them into an eagle trapped in a cage and unable to fly, OR threatens to turn the protagonists into earthworms, where they will always remember what they once were, but will be trapped in a blind, deaf, mute earthworm body. This was a threat that terrified me when I was young. In many novels, evil wizards, witches, demons, etc. make threats against the protagonists. What have you read? What's the most terrifying threat evil has made to protagonists in your experience?
