Do you think that the characters on the Discworld are parodies or originals? I'm not talking about the first two or three books, where there is little doubt on the matter, but since the books took on a life of their own. Or did they start as parodies, and mutate into something different? Or are each new central characters parodic or original? I mean, have you ever met anyone like Sergeant Jackrum or Moist von Lipwig before? I'd be interested to hear other views on this.
