Kyber memory crystal / Legends The Kyber memory crystal , or simply the Kyber crystal , was a memory crystal that contained a list of all known Force - sensitive children in the galaxy . As it was considered to hold the future of the Jedi Order , it was highly valuable to the Jedi . The information contained in the crystal could only be accessed when placed in a holocron which , in turn , could only be opened with the Force . It was vital for the operation of the Acquisition Division of the Order , for they actively sought potential students of the Force . During the Clone Wars , the crystal was kept and protected by the Rodian Jedi Master Bolla Ropal . While Ropal was on Devaron , Duros bounty hunter Cad Bane kidnapped him and stole the memory crystal . Later , during a mission to recover a holocron Bane had stolen from the Jedi Temple on Coruscant , Jedi Knight Anakin Skywalker was coerced into opening the holocron to save his Padawan ' s life . Bane then inserted the Kyber crystal into the holocron , making it possible for his client to access the information stored within . The crystal was believed destroyed , along with Bane , when the " Munificent " - class frigate they were on exploded . Bane survived , however , taking the crystal and holocron with him when he escaped the doomed frigate . Characteristics . The Kyber memory crystal was a small , blue , diamond - shaped crystal which held the identities of every known Force - sensitive child in the galaxy . This information was critical to the future of the Jedi Order , as without it , the next generation of Jedi could not be trained , and was therefore extremely valuable . The crystal was designed in such a way that its data could only be accessed if it were to be installed in a Jedi holocron . In turn , the holocron could only be opened by a Jedi ' s use of the Force . The two components were kept separate ; the holocron was stored within the Holocron Chamber of the well - protected Jedi Temple on Coruscant , while the crystal itself remained in the care of a Rodian Jedi Master named Bolla Ropal . History . Around 21 BBY , Darth Sidious hired the Duros bounty hunter Cad Bane to infiltrate the Jedi Temple on Coruscant and steal a holocron necessary to accessing the information stored on the Kyber crystal . After executing his operation and escaping the temple , Bane was given command of a Separatist task force to attack a Republic outpost on Devaron , where he kidnapped Master Bolla Ropal , the keeper and guardian of the crystal . While departing Devaron Space , Bane ' s fleet was intercepted by Jedi General Anakin Skywalker ' s flagship , the " Resolute " . The bounty hunter ' s task force was systematically eliminated by the " Venator " - class Star Destroyer until only Bane ' s command ship remained . When Bane ' s " Munificent " - class frigate attempted to escape , the Jedi ship shot the bounty hunter ' s hyper drive . Skywalker and his Padawan , Ahsoka Tano , then led a team of clone troopers and boarded Bane ' s vessel with the intent of rescuing Master Ropal and recovering the stolen holocron and memory crystal . Once on board , the Jedi were lured into a trap by the Duros hunter . Skywalker was forced to open the holocron and let Bane insert the crystal in order to save his Padawan ' s life . Bane then took the completed holocron , opened an airlock to blow the two Jedi into space , and escaped . The Jedi were able to close the airlock in time and escape the doomed ship . Bane and the memory crystal were believed to be destroyed when the frigate exploded ; however , he escaped the destruction of his ship disguised in clone trooper armor aboard the same " Sheathipede " - class shuttle Skywalker and his team had commandeered . When Bane escaped with the crystal he captured two out of the three children he was sent to get before falling for a trap planned by Skywalker and Tano . Only after Masters Mace Windu , Obi - Wan Kenobi , and Jedi Skywalker coerced Bane with the Force did the Duros take them to his hideout . Once on his space station , Windu and Kenobi were able to recover the holocron ; though Bane fled after activating the security measures installed in his sanctuary . It was said that the Bane never copied the list before it was recovered by the Order . Behind the scenes . The Kyber memory crystal was first mentioned in early drafts of as the " Kyber crystal . " It was a Force artifact sought by both the Jedi and the Sith . The plot line was ultimately removed from the story in later drafts of the script . The crystal was revived as the Kaiburr crystal in the 1978 novel " Splinter of the Mind ' s Eye " . During early development of the script for , the term " Kyber " was considered for use once again . The poison dart Jango Fett used to assassinate Zam Wesell was originally going to be identified as a Kamino kyber dart . This was again changed in the finished film to be a saber - dart . Though it has taken 30 years , the first episode in the of has made the term " Kyber " , in its original spelling , officially part of " Star Wars " canon . During " Cargo of Doom , " Cad Bane states that the holocron contains information he ' s been paid to collect . This is inaccurate , as the Kyber crystal contains the actual information and the holocron is only the means of accessing the data . It is unclear if this was an oversight by the script writers or an intentional element . Despite the name previously in " The Clone Wars " series referring to the memory crystal , the term " kyber crystal " would later be used to describe lightsaber crystal s in the " Star Wars " canon after the April 2014 canon reboot .
