Kanan Jarrus ' holocron This holocron originally belonged to Jedi Council member Master Depa Billaba , who later gave it to her apprentice , Caleb Dume , shortly after the Conquest of Kaller . History . Clone Wars . After the battle of Kaller , nineteen years before the Battle of Yavin and during the last day of the Clone Wars , fourteen - year - old Padawan Caleb Dume received a Jedi holocron from his Jedi Master , Depa Billaba . He was to use it to " study the role of questions " and " peaceful dissent " in the Jedi Order . Age of the Empire . After the fall of the Order , Dume , who survived Order 66 , was forced to hide his Force - sensitivity but managed to retain both his holocron and lightsaber . He took the name " Kanan Jarrus " and downloaded into his holocron the final holographic recording of Master Obi - Wan Kenobi that he received through his Jedi comlink . The message , which Kenobi recorded when he recalibrated the Jedi recall signal at the Jedi Temple on Coruscant , served as a warning to all surviving Jedi , telling them about the rise of the Galactic Empire and the destruction of the Jedi Order . It also contained instructions not to return to the Jedi temple on Coruscant and to trust in the Force in those uncertain times . It also had a map to all the Jedi Temples across the galaxy and a holographic recording of a lightsaber training lesson by Anakin Skywalker . Fourteen years after the Order ' s fall , the holocron was discovered aboard the rebel ship " Ghost " by Ezra Bridger . The Lothal orphan sensed the holocron with the Force and stole it , which Jarrus knew ; he and Hera Syndulla , the owner and pilot of the " Ghost " , wanted to see if Bridger could open it , as that required the powers of the Force . When he was captured by the Imperials , Bridger was able to open it with the Force and discovered the message from Kenobi . Later , once Jarrus realized Bridger ' s potential , the former Jedi offered Bridger the chance to become his apprentice , which Bridger accepted . After Bridger unknowingly tapped into the dark side of the Force to escape from the Grand Inquisitor on Fort Anaxes , Jarrus needed to know whether his Padawan was meant to become a Jedi . He thus consulted the galactic map inside the holocron for a Jedi Temple that Bridger could be tested at , discovering the most likely candidate right on Lothal . After the Spectres joined the rebellion , Jarrus stored a record labeled Holo Record 26714 in his holocron , which narrated the events they went through since Bridger came aboard their crew . In 3 BBY , following Jarrus ' and Bridger ' s duel with the Inquisitors on Oosalon , Bridger and Ahsoka Tano then watched a recording of Tano ' s former master , Anakin Skywalker , demonstrating his adjustments on Form IV techniques . Following former Sith Lord , Maul ' s capture of the " Ghost ' s " rebel crew , Bridger and Jarrus ordered by Maul to give him the Sith holocron as well as Jarrus ' holocron . When Maul forced Captain Hera Syndulla to give a tour of the " Ghost " , he discovered the holocron in Jarrus ' cabin . Maul then attempted to open it , but since he was not a Jedi the holocron refused to yield to him . When Jarrus and Bridger met Maul at Vizsla Keep 09 , Bridger was then taken to the command center . There , Maul gave Bridger Jarrus ' holocron and Bridger gave Maul the Sith holocron . Ezra then opened Jarrus ' holocron and then combined it with the Sith holocron . Maul and Bridger the looked into the holocrons and saw twin suns . There was then brief explosion that knocked everyone out and Maul left the station with knowledge that " he " still lives , the holocron however was damaged in the explosion . Though the two holocrons were damaged , fragments of their visions remained in the minds of Ezra and Maul . Seeking to discover Kenobi ' s location , Maul brought Ezra to Dathomir . There , Maul summoned the spirits of fallen Nightsisters and the two took part in a ritual to merge their minds . As a result of this ritual , both Maul and Ezra discovered that Kenobi was indeed alive and hiding on a planet with twin suns . Later , Maul used a fragment of the Malachor Sith holocron to activate Kanan ' s Jedi holocron , causing it to play back a recording of Kenobi ' s message to the Jedi during the Jedi Purge . Maul then projected a visage of himself onto the Sith holocron . This caused Ezra to believe that Kenobi was in danger from Maul . Using the two holocrons , Ezra and Chopper traveled to Tatooine where they managed to find Kenobi after an encounter with Tusken Raider s and enduring trials in the desert . Ultimately , Kenobi defeated and killed Maul . Ezra and Chopper then returned to Chopper Base .
