The Bursar of Unseen University, Dinwiddie (credentials: D.M. (7th), D.Thau., B.Occ., M.Coll., B.F.), is quite insane, but is kept hallucinating about being completely sane by taking medications derived from the nasty toxins of bright, happy tree frogs from the jungles of Klatch. A side effect is that they make him believe that he can fly. Archchancellor Mustrum Ridcully sends Dinwiddie to talk to Gunilla Goodmountain & Co. about reducing UU's printing costs. This requires reversing a long-standing policy of opposing movable type for magic purposes. Dinwiddie grants journalist William de Worde an interview after agreeing to prices, proclaiming that it is time for UU to be "dragged kicking and screaming" into or out of the Century of the Fruitbat and to embrace new technology (pg. 27.)
