Onderon Onderon was a jungle world located within the Inner Rim . During the Clone Wars , the planetary government aligned itself with the Confederacy of Independent Systems ; in the Separatist Senate , Onderon was represented by Senator Mina Bonteri and later by her son , Lux Bonteri . In response to this political posture , a rebel cell on Onderon , led by siblings Steela and Saw Gerrera , formed with aid from the Jedi . This band of rebels excised the Separatist occupation from the planet , opening the door to joining the Galactic Republic . When Supreme Chancellor Sheev Palpatine transformed the Republic into the Galactic Empire and declared himself Emperor , the planet was taken over by the Imperials . This led to the formation of the Partisans led solely by Saw Gerrera . History . In its earliest ages of civilization , Onderon was a world marked with savage jungle s that were filled with dangerous creatures . To survive , the primitive human inhabitants of the planet protected themselves behind the walls of fortified settlements . Over time , these settlements grew to become enormous walled cities , including the planet ' s capital , Iziz . Clone Wars . In the years after the Invasion of Naboo , the political idealist Count Dooku spread political turmoil on the world along with a host of others across the galaxy such as Sullust . During the time of the Clone Wars , the planet ' s monarch King Sanjay Rash allied Onderon with the Confederacy of Independent Systems . However , many Onderonian s refused to recognize the legitimacy of Rash ' s rule , as they preferred the neutral stance championed by former monarch Ramsis Dendup . This opposition led to the formation of the Onderon rebels , a group of freedom - fighters organized by Jedi Knight Anakin Skywalker . Led by Skywalker , a contingent from the Galactic Republic , including Ahsoka Tano , Obi - Wan Kenobi , and Captain Rex , helped secretly train and arm the rebels to fight against the Separatist Droid Army . Forced to hide out in the jungles of Onderon , the rebels trained how to take down droid s and tanks with the help of EMP grenades . However , in the midst of the training the training camp was attacked by a droid battalion . The rebels , with the help of the Jedi , were able to defeat the droids with relative ease . Now battle - tested , the rebels felt ready to infiltrate Iziz . Within Iziz , the rebels continued fighting against droids , covertly and systematically destroying droid patrols and checkpoints . Thinking these actions were led by the deposed Dendup , Rash ordered the former king to stop the attacks . It soon became known that Dendup was not in charge of the rebel attacks , frustrating Rash . Continuing the siege , the rebels were able to take out the droids ' main power supply by hijacking one of the droid battle tanks , knocking out the power grid after a skirmish . These actions were brought to the attention of Dooku , who was displeased with Rash for not being able to quell the insurgents . Rash blamed the droids for this and asked for reinforcements . In response , the Count sent General Kalani , a super tactical droid , to win where Rash had failed . With the power supply down , the rebels were able to take down more and more droids quite easily with little resistance . Some time later the leader of the resistance , Steela Gerrera , was able to send a message to the people of Iziz that their true king , Dendup , was silenced by Rash and that they would take back their city . This message concerned Rash , so he ordered the execution of the former king . This news made its way back to the insurgency . Steela ' s brother , Saw Gerrera , decided to rescue the former king without help but was captured by the droids . He was then brought inside the palace for interrogation overseen by Kalani and General Tandin . Kalani intended to torture Saw to death but was stopped short by Tandin who believed the droid ' s tactics ineffective against stopping the rebels . However , the droid believed that Tandin merely pitied Gererra . Saw and the general spoke with each other , the general explaining how Gerarra was viewed as a terrorist , and how Tandin chose to stay free by going under the Separatists ' rule . Saw viewed himself not as a terrorist , but as a freedom fighter trying to free his people from Separatist occupation . At the public execution of Dendup , the rebels attempted to free the king , but they were apprehended by droid reinforcements . Tandin , a witness to the rebels ' capture , gathered the royal guard and freed the imprisoned rebels . The resistance fighters were able to escape while the general held Rash as hostage . The general himself was held at gunpoint , so Tano jumped out of the crowd watching the execution and Force push ed the droids away , stunning them . The two were able to escape from the droids with the people stopping the droids going after them . Now that the Dendup was freed , the people were more rebellious against the droids and Rash ' s rule . The rebels made their way to distant mountains , where they established a base of operations . Back in the city , Lux Bonteri and Tano showed the insurgency ' s last message , now by Dendup . This message finally instigated mass action across the capital , causing riots and chaos in the city . Meanwhile droid scout s were able to locate the rebels ' hideout in the eastern mountain s . As Rash seemed helpless , Kalani assured him that with the death of both Dendup and the rebellion , fear would bring order back to the people . He also sent additional reinforcements to assist the droid army , droid gunships . As the droid army made their way to the mountains , the rebels at first were able to eliminate most of the droids very easily , but as the gunships arrived , the rebels were outgunned and outmatched very quickly . The battle seemed to lost and Tano was ordered to retreat back to Coruscant by Kenobi , reasoning sometimes people need to fight their own battles . Back on Coruscant , Skywalker did not accept the fact that the Republic should just ignore helping the rebels , so he travelled to Florrum to make a deal with Hondo Ohnaka , hiring him to illegally deliver rocket launchers to the rebels on Onderon . During the battle , the rebels were dealing with heavy casualties from the new gunship s , but the fight took a new turn when Ohnaka and a couple of his pirate s brought them the rocket launchers Skywalker ordered . The rebels were able to take down the gunships with the help of the new weapons . Back in the base , commando droids discovered the King ' s hideout and almost killed him , but they were destroyed by Steela in time . At the same time , Saw and the rebels blew up the remaining two gunships , one of which crashed at the side of the mountain the King was on . As a result of the crash , the mountain broke down , leaving Steela hanging on the edge . Bonteri came to help but was knocked down as well . Bonteri was rescued by Tano . With Bonteri safe , Tano focused her attention on Steela , and levitated Steela from the edge of the cliff . The crashed droid gunship was still marginally operational and shot a blast at Tano ' s shoulder , interrupting her Force grip ] Steela fell to her death . With Steela ' s sacrifice , the rebels rallied to defeat the droid army once and for all . Back in the city Rash was desperate , demanding more reinforcements from Dooku . Dooku however was not pleased with his lack of control , and he ordered Kalani to regroup the remaining forces and bring them back to Agamar . The droid general executed Rash as a result of his failure , and retreated from Onderon . With the Separatist army gone , Onderon was finally freed and joined the Galactic Republic . Age of the Empire . The peace bought through sacrifice during the Clone Wars was not long - lasting . The Republic reformed into the first Galactic Empire and with the Empire in control of the planet , the planet was once more occupied . Insurgent groups rose up against Imperial rule , led once again by Saw . Imperial Security Bureau Agent Kallus was tasked with tracking down and stamping out the rebels . His first stormtrooper unit was ambushed by a Lasat mercenary who worked for Saw . Kallus and his unit were caught in an explosion . Kallus was knocked out of the way . The mercenary slowly walked through the smoke and fire and killed every Imperial save Kallus , even the ones injured in the blast and unable to defend themselves .
