Long time fans will find something familiar in the term "Kyber memory crystal." In early drafts of the original script to A New Hope, the Kyber crystal was a Force-focusing artifact wanted by the Jedi and the Sith. This was eventually written out of the story in subsequent drafts, and a variation of the artifact -- spelled as the Kaiburr crystal -- made its way into the 1978 novel Splinter of the Mind's Eye. During the script development of Episode II, the term "Kyber" was nearly resurrected. The weapon that Jango Fett used to kill Zam Wesell was first identified as a Kamino kyber dart. This was changed to saber-dart in the finished movie. Finally, after over 30 years, the term "Kyber" with its original spelling has worked its way into a canon Star Wars story.
