Widely publicized as the "sequels which were never made", Zahn's novels reignited Star Wars fandom and sparked a revolution in Star Wars literature. Shortly thereafter, in the early 1990s, Bantam published Timothy Zahn's Thrawn trilogy. Developing details like this in a consistent fashion turned West End Games' Star Wars products into a de facto reference library for the Star Wars universe, to the point where Lucasfilm actually sent copies of the game supplements to other EU developers to use as source material. Stephen Crane copied those symbols and turned them into a complete and coherent alphabet (which would later be used in the feature films). For example, the Aurebesh alphabet was originally a random piece of set dressing in Return of the Jedi. In order for players of the roleplaying game to create new adventures, West End Games needed to provide supplemental material describing the Star Wars universe in previously unknown detail.

Much of this material now seems rather detached from the rest of the EU.Ī turning point was reached when West End Games began publishing the Star Wars Roleplaying Game in 1987. Much of the early EU material from the early 1980s contained analogies to the real world, rather than embracing the holistic fiction of the Star Wars films. While he worked on the novelization, he was given a copy of the working script and a tour of the production. Furthermore, while George Lucas was given sole writing credit for the original Star Wars novelization, Alan Dean Foster actually ghost-wrote it, contributing heavily to the Universe in the process. This novel drew inspiration primarily from an early draft of the Star Wars script and was conceptualized as a possible filmed sequel.


For example, the "Expanded Universe" is generally considered to have begun with Alan Dean Foster's February 1978 Star Wars spin-off novel, Splinter of the Mind's Eye (although technically it began with Marvel Comics' Star Wars #7 in January 1978). The early development of the Expanded Universe was sporadic and unrefined, particularly because there was so little official material for the creators to build on. 4.2 Lucas's use of the Expanded Universe.1.3 Etymology of the term "Expanded Universe".1.2 The Expanded Universe and the prequels.
