Kale Roshuir was a captain in the Imperial forces, specifically a male Human. He was stationed at the garrison on the planet Kalist VI during 0 ABY. After the Rebel attack on the Imperial tanker known as Nuna's Twins, Roshuir received orders to spearhead an offensive against the Rebel Alliance's base located on Thila. During their collaborative effort to identify the base's precise location, he developed romantic feelings for Deena Shan, the tanker's science officer. However, unbeknownst to Roshuir, Shan was secretly a Rebel agent who was intentionally providing him with misleading information. Her goal was to divert his troops away from Kalist VI. The Imperial forces subsequently walked straight into the Rebel trap, resulting in significant casualties among Roshuir's troops when the seemingly abandoned Rebel base detonated. Upon realizing the deception, Roshuir went back to Kalist VI and confronted Shan. However, one of the Rebels who had infiltrated the base, incapacitated him. As a result, Roshuir was unable to stop them from escaping the planet along with a group of rescued prisoners.
Later, Roshuir was given the assignment to capture Luke Skywalker, a Rebel officer. To accomplish this, they planned to use Skywalker's former friend, Janek Sunber, who was now an Imperial officer, as bait. Roshuir, along with his stormtroopers, cornered Skywalker and Shan on a space station situated within an Imperial junkyard. However, as Sunber prepared to attack Skywalker, he was wounded in the ensuing crossfire, which allowed the Rebels to escape.
During the Imperial era, Kale Roshuir, a male Human, became an officer within the Imperial Army. In the months that followed the Rebel Alliance's surprising triumph over Imperial forces at the Battle of Yavin in 0 ABY, he held the rank of captain and was stationed at the Imperial prison colony located on the planet Kalist VI in the Deep Core. After the Empire's victory against insurrectionary forces on Jabiim, approximately seven months after the Battle of Yavin, many Imperial survivors were transferred to Kalist VI and placed under Roshuir's direct command. Shortly after their arrival, Roshuir intervened in a dispute between Lieutenant [Janek Sunber](/article/janek_sunber], one of the new arrivals, and Lieutenant Clynn, an officer known to Roshuir for his history of disciplinary issues. As punishment, the captain assigned both men a double shift overseeing prisoners engaged in labor within the Imperial labor colony.

Later that day, General Noils, the base's commanding officer, summoned Roshuir to the operations center. The Imperial tanker Nuna's Twins had recently arrived at Kalist VI, having been attacked by Rebel starfighters, and Noils wanted Roshuir to formulate a counterattack strategy. Captain Harran, the tanker's commander, briefed the group on the recent attack, stating that the Nuna's Twins had first encountered their attackers in the Thila system. Roshuir recalled hearing rumors of a Rebel base in the system some time ago, and Noils instructed him to investigate whether it was being used as a staging area for a new offensive. Deena Shan, a science officer aboard the Nuna's Twins, told Roshuir that she had participated in a geographic survey of the Thila system during her Imperial training and offered to help him pinpoint the Rebel base's location. Roshuir accepted her offer, and they began working together in the base's cartography section.
Roshuir and Shan quickly identified the likely location of the Rebel base on the planet Thila, and Roshuir was selected to lead a large contingent of Kalist Base's stormtroopers in an assault on the facility the following day. The Imperial captain was impressed by Shan's intellect and became romantically interested in her, and the two spent the night together in Roshuir's quarters. The next morning, as Roshuir prepared to depart for Thila, Shan expressed her concern that he might be walking into a Rebel trap, but the captain dismissed her worries. As Roshuir's troops prepared to leave, Clynn informed him that Sunber had turned a blaster on him during a disagreement over disciplining a prisoner. Although Sunber tried to explain that he had stopped Clynn from raping the prisoner, Roshuir ordered him to remain on Kalist VI pending a tribunal upon his return.
Upon arriving at Thila, Roshuir dispatched Clynn and the majority of his stormtroopers to investigate the subterranean caverns believed to house the Rebel base, while he remained on the surface with the Imperials' Sentinel-class landing craft. Clynn soon confirmed the existence of a Rebel base but reported that it appeared to be abandoned. Roshuir instructed him to continue the search and retrieve anything of potential interest to Imperial Intelligence. Moments later, however, Clynn's search party triggered a concealed trap, resulting in an explosion that destroyed the Rebel stronghold and killed the majority of Roshuir's troops. Roshuir and the others on the surface sustained only minor injuries. In the aftermath, Roshuir recalled Shan's warning that he could be walking into a trap. Realizing that Shan had intentionally led him into the trap, the captain contacted Kalist VI to warn Noils that Shan and the crew of the Nuna's Twins were Rebel infiltrators.

Roshuir rushed back to Kalist VI, only to find it under Rebel assault. He directed his pilot to land near the Nuna's Twins, disembarked, and confronted Shan as she prepared to board. Shan told Roshuir that she had tried to warn him not to go after developing feelings for him, but the enraged captain drew his blaster on her. Before Roshuir could kill Shan, however, he was surprised by a low-flying T-65 X-wing starfighter, allowing Harran to get the jump on him and knock him unconscious. The Rebels escaped Kalist VI, having rescued numerous prisoners from the Empire, including the Rebel mathematician Jorin Sol.
Imperial Intelligence convinced Roshuir not to press charges against Sunber. Two months after the events on Kalist VI, Sunber revealed to Darth Vader, the Dark Lord of the Sith, that he was childhood friends with Luke Skywalker, the Rebel pilot. Sunber agreed to act as bait to lure Skywalker into a trap. He sent a message to his friend stating his intention to defect and instructing Skywalker to meet him at an Imperial junkyard, where Roshuir would be waiting with a squad of stormtroopers. Roshuir remained hidden until Skywalker's transport had docked, only to find Shan waiting in a corridor outside the Rebel ship while Skywalker searched for Sunber. Their reunion was cut short when Skywalker returned with Sunber, and a firefight erupted in the corridor between the two Rebels and Roshuir's squad. While Roshuir kept the Rebels occupied, Sunber attempted to seize Skywalker, but a stray shot hit him in the hand, preventing him from capturing the Rebel. Moments later, Skywalker shot the controls to a blast door, causing it to slam shut and split Roshuir's squad in two. Trapped out of the fight on the far side of the blast door, Roshuir ordered his troops to get the door open. By the time they did, however, the Rebels had boarded their ship and fled, leaving the corridor exposed to vacuum. As his men were blown out into space, Roshuir braced himself and ordered the blast door sealed again.
Kale Roshuir was an ambitious officer who believed that a victory over the Rebels at Thila would guarantee his promotion to commander. Roshuir demanded discipline from his subordinates and was quick to punish Clynn and Janek Sunber when he witnessed them fighting. When Clynn later reported Sunber for drawing a weapon on him, Roshuir suspended Sunber from combat duties pending a tribunal. Roshuir had confidence in the abilities of the troops under his command and dismissed Deena Shan's warning that Thila might be a trap. When most of his soldiers were killed on Thila, he was devastated and initially blamed himself for not heeding Shan's warning and anticipating a setup.
Roshuir was attracted to Shan from their first meeting and was eager to collaborate with her to locate the Rebel base. Impressed by Shan's intelligence and believing that they worked well together, Roshuir quickly fell in love with her. However, after realizing that Shan had led him into a trap, Roshuir was furious and, unwilling to listen to her explanation, attempted to kill her upon his return to Kalist VI. He was still angry with Shan when he encountered her at the Imperial junkyard two months later and once more threatened to kill her. Roshuir had brown hair, green eyes, and fair skin.
