Denis Lawson narrates the abridged audiobook of "Heir to the Empire", and Anthony Daniels narrates "Dark Force Rising" and "The Last Command". Lucasfilm and Varèse Sarabande Records producer Robert Townson discussed the creation of a score to promote the trilogy. All three books were adapted as comic books by Dark Horse Comics between 1995 and 1998. The series was divided into six issues per book, written by Mike Baron, who says, "I didn't invent any language. All the language is Zahn's." The first volume was illustrated by French artists Olivier Vatine and Fred Blanchard, the second by Terry Dodson and Kevin Nowlan, and the third by Edvin Biuković and Eric Shanower. The entire trilogy was collected in 2009 as a single graphic novel.
