Mission to Mustafar ( Skywalker and Tano ) / Legends Following the escape of Cad Bane from the " Resolute " over Devaron , the bounty hunter abducted several infants from their homes . The Sith Master Darth Sidious planned on using these children to create an army of Force - sensitive spies . After finding traces of volcanic ash on Bane ' s starfighter , the " Xanadu Blood " , and evidence of the bounty hunter ' s travels to the planet in his fueling records , Anakin Skywalker and his Padawan Ahsoka Tano investigated a facility on Mustafar . Prelude . In 22 BBY , the Dark Lord of the Sith Darth Sidious began to rely on the bounty hunter Cad Bane , who was considered to be the most efficient gun - for - hire in the galaxy following the death of renowned Mandalorian Jango Fett . Bane was tasked with stealing a holocron and the Kyber memory crystal , which contained a list of every single Force sensitive infant in the galaxy . Bane was then tasked with taking four children on the list to Sidious ' s lab on Mustafar , a volcanic mining planet in the Outer Rim . Bane succeeded in taking Zinn Toa , a Nautolan , and Wee Dunn , a Rodian , but was arrested during his attempted kidnapping of the Gungan Roo - Roo Page . Following a harsh interrogation session , the bounty hunter led Jedi Masters Mace Windu and Obi - Wan Kenobi to his base of operations , though this was a trap set up to ensure his own escape . While Windu and Kenobi were away on their mission , the Jedi Knight Anakin Skywalker and his Padawan Ahsoka Tano inspected Bane ' s starfighter , the " Xanadu Blood " , which had traces of volcanic ash on its hull . While Bane had wiped his navigation records , he had failed to wipe his fueling records , which revealed the four planets Bane had been to in his recent travels : Glee Anselm , Rodia , Mustafar , and Naboo . Mustafar was the only planet on the list that was volcanic , and the Jedi were previously unaware of his travels there . Skywalker and Tano traveled to Mustafar in the " Twilight " to investigate . The mission . As soon as the " Twilight " landed on Mustafar , one of the nanny droids watching over the missing children , RO - Z67 , reported to Darth Sidious that a ship had landed , and it wasn ' t Bane . Sidious quickly ordered for the gravity supports to be deactivated and for the children to be evacuated to his secondary facility . Hearing the wails of Wee Dunn , Tano guided Skywalker to the children ' s chamber using the Force . RO - Z67 deactivated the gravity supports as Darth Sidious commanded , and retrieved the children from their cradles . The droids deactivated the lights as the Jedi cut their way into the room using their lightsabers . While Tano thought the worst when they found two empty cradles , Skywalker still sensed their presence , and the two nanny droids emerged from the shadows , using the children as human shields . The facility was beginning to collapse , and Tano managed to secure Toa , slicing the droid ' s arms off , while Skywalker retrieved Dunn from RO - Z67 after the droid was forced to let go of the child to cling for its life . With the children safely rescued , the Jedi retreated to the " Twilight " just as the facility was completely destroyed . Aftermath . Skywalker and Tano brought the children back to the Jedi Temple . Since the Jedi Council wasn ' t sure of the extent of what the children were subjected to on Mustafar , the Council decided to not return the children to their parents and instead raise them in the Temple , at least for the time being . Since the entire base sank into the lava , the Jedi were unaware of Darth Sidious ' s involvement since any evidence of his involvement was destroyed . As Cad Bane escaped from Obi - Wan Kenobi and Mace Windu at Black Stall Station , a follow up interrogation was impossible . Despite this , the children were safe , and the holocron was recovered , with no sign of its information being duplicated . However , Yoda remained concerned about the future of the Jedi Order following the incident . Behind the scenes . New technology introduced during production of of " " made it possible to fit Mustafar and several other planets depicted in " Children of the Force " into the timespan of a single episode . Director Dave Filoni was initially opposed to including Mustafar in the show , since that would mean Skywalker and the other characters would be aware of the planet ' s existence during . George Lucas later persuaded him , clarifying that since Mustafar was a mining planet , it had to have had exports and been an active member of the galactic community .
