The first novel was adapted into an eight-part WaRP Graphics comic book series in the mid-1980s. Illustrated and heavily rewritten by Phil Foglio, the series was later collected into two full-color graphic novels published by Starblaze Graphics, and in 2007 Airship Entertainment (the Foglios' publishing concern) reprinted the material in a single volume. Four more issues followed, featuring an original story by Asprin and artist Jim Valentino which attempts to bridge the action between the first and second novels in the series. (Apple Comics took over the second series halfway through.) In 2010, Airship Entertainment began re-releasing the story as a web comic.
