Hosk Trey'lis

Hosk Trey'lis, a male Bothan Jedi Knight and healer, was one of the Jedi who worked on the Ossus Project—the project to have the Yuuzhan Vong terraform the worlds that had been ravaged by their invasion of the galaxy. After the project was sabotaged in 127 ABY by the One Sith, who had allied themselves with the Fel Empire, a war broke out between the Empire and the Alliance. Trey'lis managed to avoid the massacre of the Jedi Order on Ossus at the end of the Sith-Imperial War, and spent the next seven years on the run. In 137 ABY, Trey'lis was waiting in Brogar's cantina on the planet Lok for transport offworld when bounty hunter and former Jedi Cade Skywalker, along with fellow hunters Jariah Syn and Deliah Blue, burst into the cantina, seeking to capture the gambler Naxy Screeger. Trey'lis believed the bounty hunters were after him, and attempted to flee. Recognizing the Bothan was a Jedi, the hunters captured Trey'lis, and he was turned over to the Sith for the bounty cast upon living Jedi.

In the Temple of the Sith on the galactic captial of Coruscant, Trey'lis was tortured and interrogated by Darth Maladi, the head of Sith Intelligence and Assassination. Unable to resist her ruthless interrogation and torture techniques, Trey'lis eventually told her everything he knew about young Skywalker, whom Emperor Darth Krayt, the reigning Dark Lord of the Sith, sought for his healing ability. After having a vision of the Bothan, Cade traveled to Coruscant to rescue Trey'lis, only to get captured himself. A week later, after pretending to join Darth Krayt and receiving training as a Sith, Skywalker attempted another rescue, but was once again thwarted. Both Trey'lis and Cade were taken to Krayt's chambers, where the Dark Lord attempted to convince Skywalker to kill the Bothan as a show of devotion to the Sith. Not wanting to be used as a weapon, Trey'lis pleaded with Skywalker not to turn to the dark side. Krayt then struck the Bothan down, and Trey'lis's body disappeared as he became one with the Force.

Early life
A male Bothan, Hosk Trey'lis was a Jedi Knight and healer who worked with fellow Jedi Master Kol Skywalker on the Galactic Alliance-backed Ossus Project—the project to have the Yuuzhan Vong terraform the worlds that had been ravaged by their invasion of the galaxy. In 127 ABY, the project was sabotaged by the newly risen One Sith Order, who had allied themselves with the Fel Empire, sparking a war between the Empire and the Alliance. At the end of the Sith-Imperial War, Trey'lis managed to avoid the massacre of the Jedi Order on the planet Ossus, but many other Jedi were killed. Going into hiding during the deposed Emperor-in-exile Roan Fel's insurgency against the Sith-controlled Empire, Trey'lis spent the next seven years on the run, at some point losing his lightsaber in an explosion that he barely survived.

On the run
In 137 ABY, Trey'lis was in Brogar's cantina on the planet Lok, where he arranged to have transport offworld. While Trey'lis was waiting for his transport, bounty hunter and former Jedi Cade Skywalker, along with fellow hunters Jariah Syn and Deliah Blue, burst into the cantina seeking to capture the gambler Naxy Screeger, who was wanted for a debt he owed. Believing the bounty hunters were after him, Trey'lis used the Force to hurl a table at them. Realizing the chance to collect the greater bounty that was placed on Jedi, Syn went after Trey'lis while Skywalker pursued Screeger.

To ensure that the Jedi would not escape, Syn prepared to shoot Trey'lis, but was stopped as Skywalker threw Screeger into Syn's back, causing him to lose his blaster. Blue took a different approach, and attempted to slow Trey'lis down with a tranquilizer dart; however, Trey'lis was not hindered by the attack, and unleashed a wave of Force energy, throwing Blue back. Trey'lis was finally brought down by an illegal thud bug thrown by Syn, which knocked the Bothan unconscious. On the way to the bounty hunters' ship Trey'lis pleaded with them to let him go, stating that although he did not fear death, what the Sith would do to him would be far worse. Skywalker and his companions were not swayed, however, as they headed to collect their bounty.

Traveling to Socorro, the bounty hunters were attempting to take Hosk and Screeger to the Crimson Axe—an old starship that had been converted into a stationary base of operations for the pirate Rav—when Trey'lis managed to break free of the hunters' hold and run away from his captors. Skywalker pursued the Bothan, following him as he jumped off a ledge. As they fell together, Trey'lis recognized the power of the Force within Skywalker, and realized it was not a Sith trained power. After plunging into the water below, Trey'lis was dragged out of the water by Skywalker and brought before Rav, who had been watching the engagement from a holovid captured by his droids. Rewarding Skywalker, Blue, and Syn for their work, Rav ordered his crew to take Trey'lis and Screeger away. After receiving hallucinogenic death sticks from Rav, Skywalker was preparing to take the narcotic when he was visited by the spirit of his ancestor, the famed Jedi Grand Master Luke Skywalker. Pointing out that Cade had never turned a Jedi over to the authorities before, Luke attempted to dissuade his descendant from taking the death sticks, which deadened his connection to the Force. Cade refused to listen, and forced his ancestor to leave by threatening to take his own life.

Prisoner of Darth Krayt
Turned over to the Sith for the bounty cast upon living Jedi, Trey'lis was held in the laboratory of Darth Maladi, the head of Sith Intelligence and Assassination. Searching for information on Skywalker, whom the reigning Dark Lord of the Sith, Emperor Darth Krayt, sought for his healing ability, Darth Maladi interrogated and tortured the Bothan Jedi Knight. Trey'lis could not resist the ruthless interrogation and torture methods of Maladi, and eventually told her everything he knew about young Skywalker, such as his ability in the Force, and that his companions were Jariah Syn and Deliah Blue. With the information she gleaned from Trey'lis, Maladi ordered intelligence agent Nyna Calixte to personally take command of the search and to bring Skywalker back alive.

When Skywalker traveled to Ossus and began to complete his Jedi training, he had a vision of Trey'lis during one of his meditations. During his vision, Cade was once again visited by his ancestor Luke Skywalker. Instead of trying to convince Cade of his duty to the Jedi, Luke told Cade that the Sith were torturing Trey'lis on Coruscant, and it was his responsibility to make it right. Despite not having completed his training, Cade left Ossus and headed to Coruscant to rescue Trey'lis. Meanwhile, in the Sith Temple on Coruscant, Trey'lis was forced to use his healing abilities on Krayt, who was struggling to control the Yuuzhan Vong implants—gained during the Yuuzhan Vong War—which threatened to take over his body. His abilities proved inadequate, however, and Krayt continued to seek Skywalker.

Arriving on Coruscant and entering the Sith Temple in secret, Skywalker located the laboratory in which Trey'lis was being held. While being freed by Skywalker, Trey'lis sought Skywalker's forgiveness for giving in to the Sith interrogation and telling them everything he knew about the former Jedi. As the pair made their escape, Trey'lis tried to explain to Skywalker how he had betrayed him, however, Skywalker would not listen. Sensing impending danger, Skywalker Force-pushed Trey'lis out of the way just as they were attacked by one of Krayt's personal assassins, his Hand, Darth Talon. Engaging the Sith in a short duel, Skywalker was overpowered when Krayt's other Hand, Darth Nihl, joined the fight. Having succeeded in capturing the former Jedi, the two Hands took Skywalker to their Master, while the Bothan Jedi was taken back to Maladi's laboratory.

Becoming one with the Force
For a week after Skywalker's failed rescue attempt, Trey'lis was held in the laboratory, while Skywalker—having feigned allegiance to Krayt—was trained as a Sith. Meanwhile, in the underlevels of Coruscant, Skywalker's friends planned to rescue him from the Sith, aided by Skywalker's mother, Imperial Moff Nyna Calixte, who was acting under the guise of her alter ego, Morrigan Corde, in order to hide her true identity. After being held in the Yuuzhan Vong torture device known as the Embrace of Pain, Skywalker attempted another escape, and returned to Maladi's lab to rescue Trey'lis. Expecting such an attempt, however, Talon had been waiting in the lab, and the former Jedi was once again captured. Taken to Lord Krayt's chambers, Skywalker was berated by the Dark Lord of the Sith, who ordered him to kill Trey'lis to show his devotion to the Sith. Knowing that Krayt wanted him alive, Skywalker refused, stating that Krayt's threats were meaningless. In response Krayt commanded that Trey'lis be killed, which angered Cade as he did not want the Bothan to die for him. Not wanting Krayt to use him as weapon, Trey'lis pleaded with Skywalker to resist Krayt's temptations of the dark side. Prepared to die, the Bothan told Krayt that he forgave Skywalker, and that he pitied the Dark Lord. Drawing his lightsaber, Krayt struck the Bothan down, and Trey'lis' body disappeared, becoming one with the Force.
