Splinter of the Mind's Eye is a 1978 science fiction novel by American writer Alan Dean Foster, a sequel to the film Star Wars (1977).

The story focuses on Luke Skywalker and Princess Leia, who are marooned together on the world of Mimban, where they encounter the locals and struggle against the forces of the evil Galactic Empire, including Darth Vader.

[2] Though Foster was granted a great deal of leeway in developing the story, a key requirement was that many of the props from the previous production could be reused when shooting the new film.

Foster's decision to place his story on a misty jungle planet was also intended to reduce set and background costs for a film adaptation.

[2][a] Lucas's only request upon reviewing the manuscript was the removal of a space dogfight Luke and Leia undertake before crash-landing on the planet, which would have been effects heavy and expensive to film.

[3] An additional sequel novel was planned,[4] but by the time Splinter of the Mind's Eye was published, Star Wars had broken box office records.

The film adaptation of Splinter of the Mind's Eye was abandoned in favor of Lucas's vision of a big-budget sequel (The Empire Strikes Back).

A squabble between Luke and Leia attracts the attention of miners emerging from the pub, who claim that fighting in public is against Imperial law; they all get into a brawl.

Luke and Leia are placed in a maximum-security cell with two drunk but friendly Yuzzem, hairy creatures called Hin and Kee.

[11][12] With The Walt Disney Company's 2012 acquisition of Lucasfilm, most of the licensed Star Wars novels and comics produced since the originating 1977 film were rebranded as Legends and declared non canon in April 2014.

[16] Additionally, Marvel Comics' The Rise of Kylo Ren features Ben Solo traveling to Mimban, where he learns of the Mindsplinter—possibly the Kaiburr crystal by another name.
