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 gave the rebirth of the Onderon rebels once more, now led solely by Saw Gerrera.
In its earliest ages of civilization, Onderon was a world marked with savage jungles 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.
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 Onderonians refused to recognize the legitimacy of Sanjay'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 Anakin, a contingent from the 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 droids 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 the capital city of 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 King Dendup, King Sanjay Rash ordered the former king to stop the attacks. It soon became known that King Dendup was not in charge of the rebel attacks, frustrating King 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 Count 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 a Super tactical droid Kalani (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 Gererra, was able to send a message to the people of Iziz that their true king, Dendup, was silenced by King 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 Gererra, 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 Gerarry 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 King Dendup, the rebels attempted to free the king, but they were apprehended by droid reinforcements. General 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 king Rash as hostage. The general himself was held at gunpoint, so Ahsoka Tano jumped out of the crowd watching the execution and force pushed 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 king 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 Ahsoka Tano showed the insurgency's last message, now by the king Ramsis Dendup. This message finally instigated mass action across the capital, causing riots and chaos in the city. Meanwhile droid scouts were able to locate the rebels' hideout in the eastern mountains. As Rash seemed helpless, Kalani assured him that with the death of both king 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 Ahsoka was ordered to retreat back to Coruscant by Obi-Wan Kenobi, reasoning sometimes people need to fight their own battles. Back on Coruscant, Anakin 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 gunships, but the fight took a new turn when Hondo and couple of his pirates brought them the rocket launchers Anakin 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. Lux came to help but was knocked down as well. Bonteri was rescued by Ahsoka Tano. With Lux safe, Ahsoka 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 King Rash was desperate, demanding more reinforcements from Count Dooku. The Count 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 EmpireEdit
The peace bought through sacrifice during the Clone Wars was not long lasting, as the Republic was reformed into the first Galactic Empire. With the Empire in control of the planet, a rule similar to the Separatist occupation was back again.
The Imperial rule caused insurgency groups to rise, led once again by Saw Gererra. Imperial Security Bureau Agent Kallus was tasked with tracking down and stamp out the rebels. His first stormtrooper unit was ambushed by a Lasat mercenary who was working for Saw Gererra. Kallus and the unit were caught in an explosion that knocked the ISB agent away. The Lasat slowly walked through the smoke and fire and killed every Imperial but Kallus, even the ones injured in the blast who were unable to defend themselves.
