Linus Mosk was a human male smelter who worked on the planet Morlana One, and before was employed by the Consolidated Holdings of Preox-Morlana Corporation and served in the Pre-Mor Authority Security Forces as a sergeant. Due to an incident on Ferrix, Mosk was stripped of his duties and left utterly disgraced by his superiors. He eventually found work again on Morlana One in a smelter plant. Musk revered the Galactic Empire as bastions of law and order.
Following the deaths of two Preox-Morlana employees in 5 BBY, Mosk was summoned to Corporate Security Headquarters on Morlana One to meet with Deputy Inspector Syril Karn. The pair discussed the case, and agreed that they should both travel to the planet Ferrix with a squad of men to arrest their prime suspect, Cassian Andor. The squad traveled to Ferrix aboard a personnel carrier, and en route, Mosk gave a briefing to the men on the plan, splitting them into three teams. The sergeant and Karn were both in West Team and, after deploying in Mobile Tac-Pod, proceeded to the Andor household to serve the warrant. They found their target's adopted mother, Maarva Andor, and the droid B2EMO at the house, but no Cassian; however, as they questioned the droid, it was contacted by Cassian via comlink. Tracing the signal, they discovered Cassian's location, with Mosk sending East Team to surround him. Leaving two members of West Team at the house, Mosk and Karn headed toward their target's location. As they traveled, Mosk received reports the Team had been attacked and were taking casualties. He and West Team rushed to reach them, but after learning that Cassian had escaped with a collaborator, Karn and Mosk took positions on the Rix Road and waited for the pair of fugitives. After North Team arrived to join them, Mosk and his men opened fire on a landspeeder that they believed to be carrying Cassian and his partner, disabling the vehicle. However, the speeder had been a decoy, and took out several of Mosk's men in an explosion as two criminals escaped on a speeder bike.
Following the incident, the Galactic Empire ended corporate independence in the Morlani system and Mosk and Karn were reprimanded by Imperial Security Bureau Lieutenant Supervisor Blevin and sent to a transfer center. Mosk managed to find work at a smelter on Morlana One, but later learned that Maarva had died and contacted Syril to inform him of the news, believing it that Andor would resurface at her funeral. After Mosk survived the following riot, he downed a flask of drink.
Linus Mosk served as a sergeant in the Corporate Tactical Forces of Preox-Morlana, known as Pre-Mor Enforcement, during the reign of the Galactic Empire. In 5 BBY, he was summoned in the middle of the night to the Corporate Security Headquarters on the planet Morlana One to meet with Deputy Inspector Syril Karn, who was investigating the murder of two Preox-Morlana employees, Kravas Drezzer and Verlo Skiff.
Linus Mosk was recruited by Syril Karn for a mission to Ferrix.
Having been briefed on the case on the ride in, Mosk entered the headquarters bullpen and gave Karn a crisp salute as the inspector approached. The pair agreed that they needed to act swiftly in apprehending the prime suspect in the case, Cassian Andor, with Mosk suggesting that they should take twelve men to arrest them and agreed that Karn should join them. The sergeant complimented Karn on fully engaging with the case and left after the deputy inspector said he would pass Mosk's kind words along to Chief Inspector Hyne.
The next day, Mosk, Karn, and twelve men boarded a personnel carrier in order to reach the planet Ferrix, where Andor was located. While the vessel was in hyperspace, Mosk showed the men an outdated hologram of Andor and warned that their target was more formidable than he appeared. Giving the holoprojector to one of his men, he split the group into North Team, East Team, and West Team, explaining that West Team, which included Karn and himself, would serve the warrant and attempt to expedite rapidly while the other two teams took position for a pincer movement if Andor tried to flee.

Mosk finished by noting that some of the residents of Ferrix might also not be pleased with the presence of the Tactical Forces, but told his men to simply remind them that they were welcome to make official complaints at the monthly . Pivoting at a crisp ninety-degree angle, he gave the floor to Karn and fell in line behind him with his hands folded behind his back. Despite Karn delivering an uninspiring speech, Mosk began a round of applause and complimented the deputy inspector.
After the personnel carrier arrived above Ferrix, each of the three teams rode in a Mobile Tac-Pod down to the planet's surface, with Mosk traveling shoulder-to-shoulder with Karn. Banking away from the other two Tac-Pods, West Team's pod touched down among a number of refinery tanks and the squad disembarked via the rear drop ramp. As he led his men forward, Mosk reported the team's arrival over comlink, receiving sitreps from the other two groups. West Team then moved through the town toward the Andor residence, with Mosk ordering East Team to secure the position once they had landed.
Mosk and Karn served a warrant for Cassian Andor to his mother, Maarva.
At the residence, the team sounded the buzzer twice before Maarva Andor, Cassian's adopted mother, opened the door; however, when Karn announced their warrant she quickly tried to close it again. Forcing their way in before she could, the team searched the property. Mosk eventually reported to Karn that the team had discovered the family's droid, B2EMO, and the group gathered round to interrogate it. Before the droid could provide any answers, Cassian contacted B2EMO over comlink, with his voice being audible to the Tactical Forces. Despite B2EMO being unable to respond, Cassian gave him a message for Maarva, speaking for long enough that Mosk was able to track the location of the incoming call. As a crowd was gathering outside, Mosk left West-3 and West-4 to guard the house before setting out with Karn and the two remaining men from West Team.
The locals outside immediately crowded in on Mosk and his men, demanding to know what was happening to Maarva, but Mosk pushed them back and stated that it was business as usual as they were serving a warrant. The group then started the ten-minute walk to Cassian's location while East Team secured the exterior of the site. Spotting West Team, the local boy Wilmon Paak ran to tell his father, Salman Paak, who spread the word. Many locals began loudly beating hanging pieces of metal outside their houses and businesses as the streets cleared. Karn questioned what the noise meant, but dismissing it as an intimidation attempt, Mosk carried on without stopping. East Team then reported that they had Cassian's position surrounded, but the sergeant ordered them to wait for West Team to arrive. However, as East Team waited, Luthen Rael, a contact with whom Cassian was meeting, detonated on the doors of the building he and Andor were in, incapacitating two members of East Team. The remaining members of East Team reported this to Mosk, who began running to reach them as Cassian and Rael exchanged fire with East Team and downed another man.
With East Team not responding, Mosk contacted North Team and demanded to know their exact position, which they eventually reported as North Stairs Lane. The sergeant ordered them to relocate Rix Road and get a Tac-Pod in the air immediately. North Team failed to immediately respond to the order as they were confronted by the local Timm Karlo, but after one of the team killed Karlo, the team's leader responded to Mosk in the affirmative and sent the man who had killed Karlo to go and launch the pod. The last remaining member of West Team reported in and informed Mosk of the additional casualty and the fact that Cassian was not alone. With Rael and Cassian heading toward Mosk's location, the sergeant ordered the last member of East Team to keep the targets flanked. On Karn's suggestion, Mosk ordered West Team to split up and take positions around the intersection on Rix Road that they were in to prepare for Cassian and Rael's arrival. Mosk took the team's blaster rifle and set up on a roof terrace overlooking the intersection, taking a long pull from a flask as he waited.
After North Team reported to Mosk that they were also in position, the locals suddenly ceased beating on their metal, causing Mosk to ready his weapon in the sudden silence. The sergeant's attention was drawn to an explosion high on the scavenging facilities behind them, although he was uncertain of its cause, questioning if it was their targets. The explosion had in fact been North Team's Tac-Pod colliding with the structure after being sabotaged. Concerned that the explosion behind them meant that they were surrounded, Mosk swore. A landspeeder then launched from one of the buildings nearby and across the intersection, with Mosk and his men opening fire on the vehicle. Sustaining heavy fire, the speeder flipped onto its front as it reached North Team's location.
Certain that they had their quarry, Karn glanced up at Mosk, who smiled back at him; however, a speeder bike carrying Rael and Cassian emerged from the same building as the speeder and darted away in the opposite direction. Rael activated a device that detonated slap charges that the pair had hidden inside the empty landspeeder, and the exploding vehicle wiped out North Team. Mosk desperately tried to contact the downed men over comms, then rushed down to street level when he got no response. With the two targets long gone, Mosk called for bacta for the wounded men and, using the callsign Delta-One, he called in for an evacuation from as he ran to North Team. After helping one man up, he approached Karn, who stood motionless among the chaos, and told him that they needed to leave, shouting in the man's face when the Deputy Inspector did not react and dragging him away.
Following the incident, a report of what had happened reached the Imperial Security Bureau, and the entire Morlani system was placed under permanent Imperial authority, ending corporate independence. Imperial personnel arrived at Corporate Security Headquarters and began clearing it out, with Mosk, Karn, and Hyne being summoned to Hyne's office to meet with Lieutenant Supervisor Blevin, who managed the bureau's operations in the sector. As the three stood at attention, Blevin ordered them to immediately relinquish any comlinks, weapons, or scandocs, informing them that they would escorted from the headquarters to a transfer center, and would not be permitted to return to their living quarters. Any personnel items that the Imperial inspectors had had time to inventory would then be returned to them at the center, with the trio being required to holo-certify receipt of the items.
They would also be required to holo-certify confirmation of the official that detailed their involvement and culpability in the Ferrix incident, although Blevin stated they would not waste Imperial time by reading the report itself. Hyne complained that he had not been involved in the incident, causing the Lieutenant Supervisor to berate the three for the idiocy, ineptitude, and total disengagement that had led to the incident taking place. Mosk raised his hand, but lowered it when Blevin questioned the action with disdain, before informing the trio of the Imperial takeover.
Mosk lost his job as a security officer and subsequently worked at a smelter, but remained in contact with Karn.
After losing his job, Mosk remained on Morlana One and found work at a smelter, although life became tougher for the former sergeant. His at Preox-Morlana retained employment there at the headquarters night desk, and some time after Mosk's firing, his partner found him one afternoon and informed him that Maarva Andor had died on Ferrix, causing lots of Imperial communication between Morlana One and the Imperial capital Coruscant. While working the night shift later that day, Mosk queued for a communications device at the smelter during his break and called Karn, who had moved back to Coruscant to live with his mother, Eedy Karn, but asked that Mosk pass on any information he learned about Cassian.
Mosk apologized for waking Syril and his family, then, pausing frequently due to the loud sounds made by the smelter, he quickly relayed what he had learned to his former colleague. The conversation was also confused by a poor connection, but Mosk managed to convey that Cassian might return for Maarva's funeral and was pleased that Syril was still focused on Cassian after what he had put them through. As Syril tried to ask Mosk when the funeral would take place and request that they meet and speak further, the connection dropped out and the call froze.
On the day of Maarva's funeral, Mosk and Syril Karn both arrived on Ferrix to try and see if Andor would show up. Both watched the funeral in the crowd, although when they tried to get a closer look, they were halted by Imperial troops.
Mosk and Karn were present when a riot broke out between the Imperials and Ferrix's inhabitants on Fountain Square, and when a bomb was thrown onto the road; Karn leapt to save the ISB agent Dedra Meero and was followed by Mosk. However, unlike Karn, he was pushed back by an Imperial soldier. Though Mosk survived the riot, he sat alone, downing a flask of drink.
Mosk leads corpos on Ferrix
Mosk considered it a privilege to work for the Preox-Morlana, and was even glad to be roused in the middle of the night to work on the Andor case and believed there was no worthy substitute for velocity in the service of inspiring leadership. He believed Karn joining them during the arrest was a show of force that would boost morale among the men. He considered the murder of two of his colleges in the line of duty outrageous and believed anything other than full engagement on the case would be unconscionable, having seen such half-measures taken before and seeing them as a plague on discipline. He believed that the Tactical Forces needed to apply a stronger hand when dealing with affiliated planets like Ferrix, as he believed there to be pockets of fomenting among the populations there. He saw the Tactical Forces as the first line of the Empire's defense and so believed they must be used so that they were kept sharp.
Despite Mosk's strict adherence to discipline, he was shown to care greatly for his men, and was always distressed to learn about his men being injured. When he was informed two men from one of his teams were injured in a firefight with Andor and Rael, Mosk began jogging to get to their location and provide help. When Mosk saw the North Team injured by the explosive speeder Andor and Rael rigged, he immediately ran to their aid and began calling for bacta.
Mosk appears to be a very determined character. Even after he lost his job as a security officer, he and Syril Karn still went back to Ferrix to see if Cassian Andor would arrive for Maarva's funeral, signifying Mosk was no quitter.
Mosk had a stocky build, blue eyes, and blond-graying hair with sideburns.
Alex Ferns portrayed Linus Mosk in the television series Andor, with the character first appearing in the second episode, which aired on September 21, 2022. Prior to the episode's release, Mosk was visually revealed in the teaser trailer for the show and was identified for the first time in the subtitles of the first full trailer, which aired on May 26 and August 1 of 2022 respectively. Ferns greatly enjoyed playing the character. On Twitter, Ferns confirmed he would not be returning for Andor Season Two but was thankful fans enjoyed his character. In Ferns's mind, Mosk would go onto defect to the rebellion after the events of "Rix Road."
