The Aurek-Besh alphabet appears in the film Return of the Jedi and in a number of Star Wars related publications. It is used in the film to write the language of the Galatic Empire. A version of the alphabet known as Aurebesh appears in The Star Wars Roleplaying Game by West End Games and was designed by graphic artist Stephen Crane, and originally created by Joe Johnston, a designer and F/X expert on the Stars Wars films.
