Holocron fusion A holocron fusion was the merger of a Jedi holocron and a Sith holocron , which could give those who performed it the answers to any questions they asked . It required a darksider and a lightsider to work together , one to open each holocron , so they were rarely performed . Ending the fusion before the holocrons were done could destroy the holocrons used , and cause the two Force users who performed it to get snippets of the information the other was searching for . It was also possible for strong emotions to affect the fusion , causing the answers given to be skewed . By the eve of the Galactic Civil War , knowledge of holocron fusions was rare . History . In 2 BBY , the former Sith Lord Maul captured the crew of the rebel starship " Ghost " because he knew that the Jedi members of the crew , Kanan Jarrus and Ezra Bridger , had both a Jedi and a Sith holocron in their possession . Maul had encountered the two Jedi previously . He held the other Spectres , Hera Syndulla , Sabine Wren , Garazeb Orrelios and Chopper , hostage on the ship with the help of reprogrammed tour guide droid s in order to force the two Jedi to retrieve the Sith holocron , which Kanan had left with a mysterious Force wielder called the Bendu . Kanan ' s Jedi holocron was in his cabin on the " Ghost " where he always kept it . After retrieving the Sith holocron , Kanan and Ezra were told of holocron fusions by the Bendu , who warned of the incredible damage they could do . The two Jedi met Maul at Vizsla Keep 09 , where he had taken the " Ghost " . After attempting to kill Kanan and ordering his droids to execute the prisoners , Maul had Ezra , who had been immediately escorted to the station ' s control room , start the fusion with him . Ezra wanted to find " the key to destroying the Sith " , while Maul claimed he only wanted " hope " . The ex - Sith actually wanted to find out if his archenemy Obi - Wan Kenobi was still alive and if he was , where he was hiding so Maul could find and kill him . As the two were going deeper into the fusion , the other Spectres arrived at the control room . Kanan advised Ezra to look away , reminding him of the Bendu ' s warning , and the Padawan eventually did , cutting the fusion short and destroying the holocrons . Maul discovered that Kenobi was still alive , but Ezra was left with a collection of visions of places , only some of which he was familiar with . As the fusion had been cut short , Maul and Ezra were left with the information mixed up between them . Maul was left with the location of Chopper Base on Atollon , which the Spectres and Phoenix Cell operated out of . He tracked Ezra and Kanan down on the planet some time later , and persuaded Ezra to come to Dathomir to participate in a ritual which would give them each the information they had been searching for . Doing so , Maul found out that Kenobi was on Tatooine , and Ezra saw that the Jedi Master was the key to destroying the Sith . Months later , Maul , unable to find Kenobi in Tatooine ' s endless desert , used a fragment of the Sith holocron he had taken to lure Ezra to the planet . The plan worked , and Ezra and Chopper became lost and nearly died , calling Kenobi out of hiding to help them . When Ezra insisted that Kenobi was the key to destroying the Sith , because of what the fusion had told him , the Jedi Master told him that Maul ' s desires had skewed the fusion , showing Ezra what the ex - Sith had wanted to see . Ezra and Chopper were sent on their way back to Atollon just after Maul arrived , and Kenobi killed the weakened darksider in a duel .
