The Carreras Incident constituted a fleet operation. This event unfolded within the Carreras system during the year 138 ABY. Under the command of Darth Wredd, who was masquerading as the Imperial Knight known as Yalta Val, a blockade composed of Carreras starfighters was established. Wredd's objective was to prevent any vessels from entering or exiting the Carreras system until the Carreras G51 communications array was fully constructed. Governor Biala, despite her reservations, ultimately consented to the implementation of the blockade.
After escaping from Shifalan security forces situated on the moon of the obscure planet Carreras Minor, Ania Solo, Sauk, and AG-37 detected the blockade from aboard AG-37's freighter. Subsequently, they were pursued into the ice rings surrounding Carreras Minor by snubfighters originating from the blockade. Shortly thereafter, Jao Assam, an Imperial Knight, was apprehended on the Sith's orders while aboard the blockade. However, he managed to escape to Carreras Minor after the Shifala attempted to arrest him. Assam surmised that the presence of the blockade indicated that something was amiss within the system.
Later, Solo's group was captured by a Shifalan patrol ship and detained on the communications array. Biala facilitated their release, leading to their attack on Wredd. With the exception of Solo, all members of the group sustained severe injuries. Solo then seized control of Assam's starfighter to pursue Wredd to the planet Mala. Upon arrival, she aided in freeing Yalta Val. Subsequently, she returned to the array and rescued her companions aboard AG-37's freighter before the communications array crashed into Mala and was destroyed. On the surface of Mala, Val engaged Wredd in a duel, mirroring their previous encounter. However, Wredd fled before the array could collide with them. Solo also rescued Val just in time.
Following the defeat of the One Sith, which marked the conclusion of the Second Imperial Civil War, a novel governing body emerged, known as the Galactic Federation Triumvirate. This Triumvirate comprised the Fel Empire, the Jedi Council, and the Galactic Alliance Remnant. Marasiah Fel, the newly appointed Galactic Empress, initiated an ambitious project focused on communications infrastructure. This initiative, referred to as the G51 communications array, aimed to enhance communication between the Outer Rim Territories and the rest of the galaxy. The remote Carreras system, situated within the Outer Rim, was selected as a site for one of the G51 communications array's component stations. In the year 138 ABY, Empress Fel dispatched Yalta Val, an Imperial Knight, on a mission to oversee the final phases of construction of the Carreras communication array.
While traversing the treacherous Surd Nebula, Yalta Val's starship was subjected to an ambush and attack orchestrated by a Sith master and his apprentice, Darth Wredd. In the aftermath of Darth Krayt's demise, the One Sith had retreated into the shadows but had reorganized with a revised strategy of infiltrating various galactic governments and corporations to reinstate their "golden age." During the ambush, Darth Wredd persuaded his master to target Yalta Val's starship, resulting in its crash-landing on the floating world of Mala. There, Yalta Val's crew and stormtroopers were slain by the Sith master. Before the Sith master could eliminate Val, he was killed by his own apprentice, Darth Wredd, who declared the termination of his apprenticeship. He disarmed and captured Yalta Val, assuming the identity of the Imperial Knight and appropriating his armor. Despite his success, Darth Wredd was unable to retrieve Val's lightsaber, which had been recovered by his comm droid. Subsequently, the comm droid was found by Ania Solo, a young Human junk dealer and a distant descendant of Han Solo, along with her Mon Calamari friend Sauk.
One week later, Darth Wredd, masquerading as the Sith impostor, was apprehended by Governor Biala's security forces. Under the guise of a Sith presence within the Carreras system, the false "Yalta Val" coerced Biala into relinquishing personal control of her security forces to him. Darth Wredd's true intention was to recover Yalta Val's lightsaber. While conducting a search through the streets of Carreras Major, the homeworld of the simian Shifala species, the Carreras security forces discovered that Ania and Sauk had acquired Yalta Val's lightsaber. During the recovery attempt, Ania killed a Carreras security officer. She and Sauk then fled in a speeder, leading the Carreras security forces on a chase that resulted in the deaths of four security officers. Subsequently, they sought refuge at Ania Solo's junkyard on the moon of the remote planet Carreras Minor. Upon learning of the incident, Darth Wredd mobilized a contingent of Carreras security guards and traveled to Ania Solo's junkyard to personally recover the lightsaber.

Shortly before Darth Wredd's arrival, AG-37, a friendly assassin droid and acquaintance of Ania Solo, visited Ania Solo's junkyard to purchase a linear converter. Their reunion was disrupted by the arrival of the false "Yalta Val," who demanded that Ania return "his" lightsaber to him. Ania refused, asserting that she had found it first, and dispatched her security droid SD to confront the intruder. However, the Sith impostor simply employed the Force to levitate the lightsaber from Ania's grasp and bisect SD across the torso. Motivated by either bloodlust or a desire to conceal his actions, Wredd then instructed his security guards to eliminate Ania and Sauk. Following a pursuit through the junkyard, the Carreras security guards were killed by AG-37, who opened fire on them with two blaster rifles. Capitalizing on the purported threat posed by Ania, Darth Wredd seized the opportunity to mobilize all of Governor Biala's troops for active duty and impose a blockade on the Carreras system.
Ania and her companions fled into space aboard AG-37's freighter, accompanied by the damaged comm droid. They were pursued by several Shifala snub fighters but managed to evade their pursuers within the ice rings orbiting Carreras Minor. Seeking refuge from the Shifala authorities, AG-37's freighter landed on the desolate planet. Having received no communication from Master Yalta Val, Jao Assam, an Imperial Knight, traveled to the Carreras system to investigate delays in the Carreras communications array project and ascertain Val's whereabouts. Upon arriving outside the Surd Nebula, Jao encountered a Shifala naval blockade. After narrowly avoiding arrest by the Carreras security forces, Jao traced Val's comm droid's locator signal to Carreras Minor. There, he rescued Ania and her companions from being devoured by a colossal tentacled creature. After learning from the comm droid that Yalta Val had been replaced by a Sith impostor, Ania, Jao, Sauk, and AG-37 resolved to join forces to rescue the Imperial Knight.
Jao and Ania's companions departed in AG-37's freighter for the dark planet of Mala, reportedly situated at the heart of the Surd Nebula. However, they discovered only empty space and were subsequently captured by a Shifala warship and transported to the Carreras communications array. Meanwhile, relations between the false "Yalta Val" and Governor Biala deteriorated. Following delays in the activation of the Carreras communications array, Yalta Val nearly Force choked a Shifala engineer. However, the breaking point occurred when the Sith impostor demanded the execution of Jao's companions. After overhearing a conversation between Jao and the Sith impostor, Governor Biala released Jao and his companions and dispatched them to stop the Sith impostor. Jao, Ania, Sauk, and AG-37 successfully tracked Darth Wredd to the space station's hangar bay.

At the Carreras station's hangar bay, Darth Wredd was boarding a shuttle to return to his hidden base on Mala. Recognizing that he and his friends could not defeat a Sith without the assistance of another Force-user, Jao suggested sneaking back aboard AG-37's freighter and then tracking Yalta Val's location. However, Ania was determined to eliminate the Sith impostor once and for all. Against Jao's advice, she fired upon the thruster engine of Darth Wredd's shuttle, causing the starship to erupt into flames. However, Darth Wredd survived the explosion due to his mastery of the Force and Force choked Ania. Jao, Sauk, and AG-37 quickly intervened to rescue her. However, Darth Wredd bisected AG-37 with his lightsaber and used the Force to render Sauk unconscious. During a brief lightsaber duel, Jao managed to blind Wredd's right eye. However, the rogue Sith used the Force to impale the Imperial Knight with a pair of rods, causing him to plummet from the hangar bay into the vacuum of space. Wredd then swiftly commandeered another shuttle and fled to his base on Mala.
Having survived the skirmish with Darth Wredd, Ania Solo followed him back to his base on Mala in Jao Assam's starfighter. Meanwhile, Governor Biala issued orders for her subordinates to shut down the Carreras communications array. However, Darth Wredd had already seized control of the space station from his Mala base and used it to broadcast his message to the galaxy. During his broadcast, Darth Wredd presented the captive Yalta Val and mocked the Galactic Federation Triumvirate in an attempt to sow doubt and fear among its citizens. The broadcast was witnessed by many across the galaxy, including Governor Biala, Empress Fel, the Imperial Knight Antares Draco, and the Ithorian crew aboard the substation in the Ottega system. After boasting about his feat in misleading an entire star system, Darth Wredd attempted to kill Val but was thwarted by Ania Solo, who managed to free Yalta Val and pass him Jao Assam's lightsaber. The newly freed Val engaged the rogue Sith in a fierce lightsaber duel.
Amidst the fighting on Mala, Governor Biala ordered her crew to evacuate the Carreras communication array as the space station hurtled toward a collision course with Mala. Meanwhile, Ania managed to escape Darth Wredd's base and returned to the Carreras space station. She managed to rescue the wounded Sauk and AG-37 and escape the communications array in AG-37's freighter. Back on Mala, Yalta Val managed to destroy Darth Wredd's lightsaber, but the rogue Sith managed to escape in a get-away starship. Before the space station collided with Mala, Ania succeeded in rescuing Yalta Val. AG-37 then piloted the freighter through the Surd Nebula. Since Ania had already patched up the damaged starship's hull breach, they were able to travel through the dangerous nebula safely. While tending to a wounded Sauk, AG-37's freighter came across Val's comm droid and Jao Assam.
The comm droid had attached a breathing mask to the wounded Jao Assam, saving him from certain death in zero gravity space. Yalta was amazed that a droid would step in to safe the life of a sentient being. AG-37 explained that the comm droid was returning a favor to Jao for traveling to the Carreras system to rescue it. While Jao Assam was grievously wounded during his duel with Darth Wredd, his condition was stabilized due to timely intervention by a medical droid. While Ania expressed regret that her actions had caused them trouble, Sauk assured her that she had saved them all.

Following the destruction of the Carreras communications array, Governor Biala submitted a report on the Carreras Incident to the Galactic Federation Triumvirate's leadership. While the Governor was unclear about what had exactly happened, she reported that a Human woman named Ania Solo was involved in the destruction of the space station. In response, Galactic Empress Marasiah Fel sent a Star Destroyer Animus to pick up Ania and her companions. Following their rescue and recovery, Yalta Val and Jao Assam were reassigned to the galactic capital Coruscant to supervise the recruitment and training of new Imperial Knight cadets. After encountering a Force vision of Darth Wredd attacking Empress Fel, Jao decided to abandon his assignment and embark on a manhunt for Darth Wredd. He managed to convince Ania to accompany him and the pair traveled to Nalyd, the homeworld of Wredd's henchman Dieben in the hope of discovering the rogue Sith's whereabouts. However, their trail led them instead to the Calamari system where they discovered that another rogue Sith named Darth Luft and his pirate associates were building a pirate fleet using Mon Calamari and Quarren slave labor.
Meanwhile, Darth Wredd embarked on an insurgency to hunt down and kill members of the One Sith. Following the end of the Second Imperial Civil War, the One Sith had gone underground and embarked on a campaign of infiltrating all galactic governments and corporations with the aim of restoring their lost "golden age." On Ceitia Five, Wredd killed a Sith infiltrator in the Triumvirate's legation. Wredd then traveled to Cadomai Prime where he killed a Snivvian Sith, who was also posing as a diplomat. Despite the threat posed by Darth Wredd, the Triumvirate authorities decided not to hunt him down since he was helping them do the job of rooting out the One Sith. This enabled the Triumvirate to concentrate on their task of rebuilding the war-torn galaxy.
The Carreras Incident served as the main exposition of Star Wars: Legacy: Prisoner of the Floating World, the first five-issue story arc in Corinna Bechko and Gabriel Hardman's Star Wars: Legacy Volume 2 comic series. It serves as the main conflict of that story arc.
