After the defeat of Yuuzhan Vong, Luke and Mara decided to spend more time with their son, but the hardships of leading the new jedi order led to their frequent separation. During the swarm war, Ben inadvertently became friends with the killer bug in Gorog's lair, unaware that he brought danger to his family. In the meantime, Luke and Mara find that Ben is more willing to open his heart to his cousin jacen solo. So they asked Jason to take care of Ben. As time went on, Ben began to tentatively contact the Force. With Jason's help, his connection with the Force gradually strengthened. As an apprentice, Ben wore a braid to show his identity according to the ancient tradition, but it was not necessary for New jedi order. He can also remember what he saw or heard very accurately.
After the swarm war, Ben, as a Jedi, continued to receive training under the guidance of Jason. At the age of 13, he accompanied Jason to the central station and was ordered to disable the facility to prevent Slakan Sal-Solo from restarting it and using it as a weapon. Then, after Jason was caught by Sal Solo, they were forced to separate and planned to complete the task independently. Ben found an unusual robot, which was programmed as anakin solo. Ben persuaded it to shut itself down to prevent it from being used as a weapon. After returning to Coruscant, Ben knew that he was no longer a child, especially when he gradually realized that his paralysis of the central station had greatly deepened the growing contradiction between Colelli people and the Galactic Alliance. He became friends with a young man named Barit Say on Coruscant, but he joined the cause of corelli people. This encounter forced Ben to choose between friendship and the responsibility of the Galactic Alliance. Finally, Ben told the Coruscant police the location of Say's house.
Jason and Ben's next destination is the Hapis Cluster to stop the plot to assassinate Tanel Ka. The Duchess of Ghana was proved to be involved in the case. She would rather destroy her family apartment than kill the Jedi who came to her. When han solo and leia organa solo arrived in the Millennium Falcon, Jason and Ben successfully foiled the plot. But Ben arrested his sister-in-law and uncle because he thought they were Corea rebels. When Jedi Knight Zeke tried to intervene, Ben also wounded him, which made Ben even more uncertain about how to judge the loyalty of his loved ones.
After the Hapes operation, Jason gave Ben a secret task: to find carrara's amulet. At first, he went to Sioster, a Sith planet, where the energy of the dark side lured him to yield to the most primitive instinct. Ben returned to Jason with a Sith ship found in West Oster, expressing his doubts about the mission and ambivalence as Jason's thug. This made lumiya, Jason's Sith tutor, very worried and doubted whether Ben was suitable to be Jason's apprentice.
Later, Jason suggested that Ben lead a team to assassinate Dole Gezhen, the Prime Minister of Correa. Ben took two agents, Yuri Lekov and Langshewu, to Walport, shot Gaizhen in the head and killed him on the spot. Security guards swarmed in, and Lekov gave his life to ensure that Ben and Shewan were all evacuated. Lekov's death was a great blow to Ben because they had become good friends. Ben confessed his crime to his mother on Coruscant, and Mara was angry with Jason for distorting and manipulating her son.
Soon after, in the space war over Kavan, Jason and Lumiya forced Mara's "stealth X" fighter plane to land on the surface of the planet. Ben longed to find his mother, but he felt her death in the energy waves of the Force. He found Mara's body in the storm tunnel. Jason suddenly appeared to comfort Ben that he must find Mara's killer. They took Mara's body home. Luke killed lumiya to avenge Mara, but after Ben explained the Kavan incident to him, Luke realized that Lumiya couldn't be the murderer. Ben gradually believed that Jason killed his mother, but Jason hinted that Carl Omas, the former head of state of the Galactic Alliance, was suspected. In order to regain Jason's trust, Ben confronted Omar. Aumas realized that Jason's evil behavior could only be revealed at the expense of his own life, so he committed suicide.
Ben went back to Jason. In the attack on Kasik, he tried to assassinate Jason, but this bold act gave Jason reason to believe that Ben might still be a Sith. Jason put Ben in the "arms of pain" on the Star Destroyer anakin solo, but Luke sneaked into anakin solo and rescued Ben. Before Jason attacked Luke, Ben inserted a vibrating knife into Jason's back, and then the father and son evacuated, leaving Jason to fend for himself, but Jason-Darth Cardus in the plot-survived and continued to do evil.
Ben decided to track down the real killer of his mother. He restrained his strong doubts about Jason and focused on fair forensic procedures. This is what he learned when he was trained in the Galactic Alliance Guard. With the help of Ron Sherwood, I collected a lot of evidence against Jason. At the same time, he mended the tense relationship with his father and helped Luke finally get rid of the pain of losing his wife. After learning that Jason succumbed to the dark side, the Skywalker family, the Solo family and their friends worked out a plan to bring Jason to justice. Ben was promoted to a Jedi Knight and was ordered to accompany Jenna Solo on a Jedi-approved mission to destroy the real Sith Lord Darth kardos. Ben was intercepted by Tahiri Villa on Coruscant and then brought to trial, which almost led to the termination of the mission.
Ben used the Force shielding skills he learned from Jason and refused to answer any questions. Vera even tortured and killed Shewu in front of Ben, but Ben remained unwavering. With Shewu's life no longer a burden, Ben realized that he had the upper hand. He stimulated Vera to slap him hard; This caused his chair to tip over, causing the scene to get out of control instantly. Ben used the Force to push Vera in front of her two guards and escaped.
Ben returned to the secret Jedi base in Shedumad. When the news came that Darth kardos had followed Jenna Solo here, Ben was in charge of evacuating the young Jedi. As Vera led the Imperial Army into the war, the battle of Shedumad became more and more complicated. When hitting Vera, Ben advised her not to fight again, hoping that she would return to the smooth side. With kardos's inevitable defeat, Villa had no choice. She began to listen. Ben was willing to help her return to jedi order. Vera was skeptical, but realized that Ben was always right about Darth kardos. She finally surrendered.
