A journey to Carnelion IV was carried out by Jedi Knight Obi-Wan Kenobi together with his Padawan apprentice, Anakin Skywalker, a mere three years following the Invasion of Naboo. They were sent to look into a distress signal that was coming from the planet known as Carnelion IV.
Quite a few generations prior to the Naboo Crisis, a war amongst themselves erupted among the human residents of the Carnelion IV world. The Celadon Sea contaminated the world's surface, which made the remaining people go to the mountains. As Carnelion IV lacked resources that piqued the interest of the Galactic Republic, the Galactic Senate didn't see any need to step in or provide assistance to its population. Being left to fend for themselves, Carnelion IV's inhabitants divided into a pair of feuding groups: the Open and the Closed.
What little technology the Open and Closed possessed was recovered from the planet's surface. To wage war against one another, the two factions constructed airships. An older woman named Sera, a devotee of the Jedi Order, dedicated her life to gathering remnants of "the world that once was". From her fortress museum located on the ruined surface, Sera would dispatch kites bearing art with the intention of influencing the younger generation.
Sera came to the conclusion that the adult Open and Closed members were beyond saving, and thus resolved to seek the Jedi's aid in eradicating them. She succeeded in reactivating a malfunctioning transmitter and employed it to transmit a coded message requesting assistance from the Jedi Order. Jedi Master Yoda intercepted this transmission, and he subsequently dispatched Jedi Knight Obi-Wan Kenobi along with his Padawan Anakin Skywalker to investigate. At that point in time, Skywalker had become disillusioned with his Jedi training and was contemplating leaving the Order.
Kenobi, a Jedi Knight, and Skywalker, his Padawan, made their way to Carnelion IV aboard a T-6 shuttle, which suffered significant damage as it maneuvered through the thick debris field above Carnelion IV. Although their ship went down, the two Jedi were able to get out using ejection seats. Even though they initially thought that Carnelion IV was deserted, the two soon came across an aerial battle between Open and Closed airships.
Spotting an airship that was crashing, Kenobi and Skywalker used the Force to draw the airship nearer to their cliff, which allowed two survivors to leap to safety. The Open leader, Mother Pran, and Kolara turned out to be these survivors. While Kolara was welcoming, Mother Pran was unfriendly to the two Jedi newcomers, unaware of their identities. Not long after, a Closed airship strafed them. Kenobi used his lightsaber to puncture the airship's airbag, resulting in the airship's explosion.
Anakin was successful in saving one of the Closed survivors, who turned out to be Grecker, a fierce adversary of Mother Pran. Anakin made an effort to break up the fight by using his lightsaber to cut through their blasters. They then attempted to stab each other, but Kenobi used the Force to restrain their blades. Kenobi was successful in persuading the two combatants to accompany him and Skywalker on their mission to locate the source of the distress signal. Grecker chose to accompany the Jedi because he was unwilling to freeze on the mountaintop or cross the Celadon Sea without weapons. Kolara persuaded Mother Pran to heed the Jedi.
Skywalker got the Open and Closed to set aside their differences in order to fix a damaged Closed gondola by retrofitting it with an Open airbag. They were attacked by a number of winged corpse-leeches while repairing the ship. Kenobi was able to use the Force to calm them down, but Skywalker, who struggled with patience, slaughtered those nearby. The Jedi traveled with their local guides on the airship into the Celadon Sea after completing their repairs.

The Jedi, along with their local companions, piloted their airship across the Celadon Sea, which was dotted with numerous ruined cities blanketed in toxic gas. Their airship came across a kite carrying a circular art disc during their flight. Grecker, however, threw it to the ground. Kolara later showed Skywalker a stunning circular disc that she had acquired. While Kenobi became friends with Grecker, Kolara also became friends with Anakin, who was about her age. Anakin wowed Mother Pran and Kolara with his talent for fixing a remote, which Pran wanted to use to give the Open an advantage over their Closed enemies.
Later, the airship was attacked by a number of Fishers, mutated humans who attached ropes to the airship. Kolara distracted Skywalker by throwing out his lightsaber while Kenobi and Grecker fought off the Fishers, allowing Pran to knock him unconscious with a wrench. Pran and Kolara then used a glider to get away with Skywalker. Mother Pran tried to kill Kenobi and Grecker before leaving by blowing up their airship's gasbag, which caused the gondola to crash onto the surface below.
Kenobi and Grecker made it through the crash in spite of Pran's best efforts. Kenobi was able to use the Force to persuade the Fishers to leave them alone. Kenobi made the decision to press on with the mission to find the coordinates of the distress signal because Mother Pran had taken Anakin to one of the Open's mountainside fortresses. He was confident in the Padawan's ability to find him because Skywalker was aware of the distress signal's coordinates. They made their way through the ruined city while wearing gas masks.
Kenobi and Grecker tracked their signal to a dilapidated structure. Kenobi started to have doubts about Grecker's motives for assisting him. When Grecker fired a flare gun while the pair were being attacked by a number of Carnelian dragons, this suspicion was confirmed. A masked woman ushered Grecker inside the building. She wanted to hold the door open for Kenobi, but Grecker insisted that she shut it. The masked stranger rejected his demands and wounded Grecker, leaving him to die. When a shocked Kenobi questioned his rescuer, she claimed that Grecker would have abandoned him to the beasts.
The masked woman introduced herself as Sera and verified that she was the one who had contacted the Jedi Order. She then showed Kenobi her fortress museum, which was made up of artifacts from the "world that was" that had been salvaged from the "Dead lands" outside. She confirmed that she had sent the kites with treasures in the hope of influencing the young. However, Sera came to the conclusion that the adult Open and Closed were beyond redemption because they were too set in their ways. She revealed that her real intention was to bring the Jedi to Carnelion IV in order to wipe out the Open and the Closed in order to rebuild her planet's civilization. Sera informed Kenobi that both the Open and the Closed wanted to kill her because she served as a reminder of the past they had lost.
In the meantime, Mother Pran and Kolara brought a gagged Skywalker back to their Fortress-Home of the Open, referring to him as a Skygift. Mother Pran reactivated a Mech using the remote that Skywalker had fixed. She was certain that the Open would be unable to defeat their Closed adversaries.
Later, Mother Pran coerced Anakin into revealing the location of the distress signal, claiming that Grecker was plotting against Kenobi. Anakin sensed that was a lie but told them that the distress signal was located another half day's travel past where the Fishers had attacked them. Skywalker wanted to accompany them to save his master. However, Mother Pran wanted to kill the Scavenger and kept Anakin behind, telling him that he was valuable to their plans. Before departing with the Open forces, Pran tasked Kolara and the other youths with guarding Skywalker.
After the Open adults have left, Kolara and the other youth come to believe that the Scavenger, who sent them beautiful art, was the source of the distress signal. They realized that the adults were going to hunt down and kill the Scavenger, who sends them beautiful art on kites. Anakin, who was listening, told them that the "Scavenger" showed them how things were like in the past and how they could be different. After learning that the other youths shared Kolara's interest in art, Skywalker enlisted their hep in reaching the Scavenger.
While Sera was regaling Kenobi with legends of the Jedi, a large force of Closed warriors and airships lay siege to her fortress museum. Sera demanded that Kenobi kill them but Kenobi responded that the Jedi spared everyone. Kenobi confronted the leader of the Closed force and asserted his protection over Sera. When the Closed leader demanded to know where was Grecker, ther warrior resurfaced and urged his comrades to kill Kenobi and burn the palace to the ground. Kenobi deflected their blaster bolts with his lightsaber while trying to reason with them.
Just then, Mother Pran and her force of Mechs and airships entered the battle. Kenobi tried to reason with Grecker by telling him that Sera was trying to save his world. Grecker dismissed Kenobi as a fool before being hit by a laser cannon. Kenobi survived but found himself facing Mother Pran's mech. He demanded to know where Skywalker was but she fired upon him. However, he was rescued by Anakin, who had arrived on a flying machine. Anakin was accompanied by the Open youth, who also had flying machines.
Returning to the fortress museum, Sera blamed Kenobi for ruining her plans to rebuild a new order with the young people of her planet. Sera hoped that the Open youth would stay with her while the adults killed each other. However, Kolara and her peers decided to join their brethren in the battle despite Sera's protests. Anakin managed to repair transmitter which allowed Kenobi to contact the Republic for help. A Judicial Forces fleet consisting of Consular-class cruisers arrived and forced the Open and Closed to cease fighting.
Kenobi and Skywalker's mission to Carnelion IV re-established contact between the Republic and the inhabitants of Carnelion IV. Jedi, Judicial Forces, and droids tended to the wounded. Following the battle, Kenobi told Skywalker that he had told the Republic that the planet's atmosphere had high concentrations of tibanna gas, a valuable resource. While the Republic conducted an exploration survey, they forced a ceasefire. Kenobi hoped that the Republic's intervention would end the conflict between the Open and the Closed. Kenobi is unsure whether this is true, but said that the Republic will not allow any fighting for the duration of their survey and hoped this will bring peace to the world and that the locals can help themselves.
Anakin came to the realization that the Jedi Order possessed considerable respect and authority within the Republic as a result of their experiences on Carnelion IV. Skywalker chose to set aside his reservations and carry on with his training under Kenobi. During the Separatist Crisis and the Clone Wars, the two would continue to serve the Jedi Order and the Republic. Even though Anakin succumbed to the dark side and joined the Sith and Galactic Empire, he was brought back to the light side with the assistance of his son Luke Skywalker and was instrumental in restoring equilibrium to the Force. Kenobi managed to live through the Great Jedi Purge long enough to guide the younger Skywalker through his initial steps in the Jedi way prior to his death at the hands of his former apprentice.
