During the High Republic Era, Sol was a highly regarded Jedi Master who was male and human. A defining aspect of Sol's life was a mission to the planet of Brendok that occurred in 148 BBY. On this mission, he, along with fellow Jedi Masters Kelnacca and Indara, as well as Indara's Padawan Torbin, sought to determine if a Force vergence had revived the world following the Great Hyperspace Disaster that had happened almost a century prior. While present, the Jedi discovered a coven of witches who were sheltering two girls, the twin sisters Verosha "Osha" and Mae-ho "Mae" Aniseya. The Jedi tested the girls to see if they were suitable to become Padawans. Following a string of misunderstandings, Sol killed Aniseya, believing that this action was necessary to safeguard the girls. The resulting chaos led to the deaths of the majority of the witches in the coven. Sol tried to rescue both twins, but he ultimately chose Osha over Mae, presuming that Mae had died as a result of the events. The four Jedi then lied to the Jedi High Council about what transpired, asserting that Mae was solely responsible for the destruction. Sol then took Osha as his Padawan without revealing the truth of what had taken place. Eventually, Osha departed from the Jedi Order, and Sol later accepted Jecki Lon as another Padawan.
In 132 BBY, Mae reappeared and initiated a quest to exact vengeance on the four Jedi, beginning with the murder of Indara. After Osha became the primary suspect, Sol reunited with his former student, and the two, accompanied by Lon and Yord Fandar, pursued Mae together. After verifying Mae's survival following the murder of Torbin, Sol, Osha, and the Jedi travelled to Khofar with the intention of intercepting Mae. However, they instead encountered "the Stranger," the clandestine Sith Lord who was Mae's master. Lon and the other Jedi were killed, but Sol defeated the Stranger and managed to escape the planet, accompanied by Mae, who had disguised herself as her sister.
After Sol discovered Mae's deception, the two returned to Brendok to confront the Stranger. There, Sol confessed to his wrongdoings in the presence of both Mae and Osha, although he still defended his actions, believing that he had done what was necessary to protect the twins. Enraged by the revelation that her master had deceived her throughout her life, Osha used the Force choke ability to end Sol's life, claimed his lightsaber as her own, and bled its kyber crystal, thus becoming the Stranger's new Sith acolyte.
Sol's colleague and friend Vernestra Rwoh discovered Sol's body and gave him a Jedi funeral pyre. However, she would falsely accuse Sol of the Jedi deaths caused by the Stranger and Mae, and his own suicide, claiming that he had killed his fellow Jedi in order to maintain their "cover story" about what happened at Brendok. She used Sol as a scapegoat to protect the Jedi Order's image in the eyes of a Galactic Senate that was becoming increasingly critical.
At the age of four years, Sol was taken to the Jedi Temple to join the Jedi Order. Despite his fear of leaving his family, Sol found solace among the thousands of other gifted younglings at the Temple, although he was also naturally reserved.
In 148 BBY, Jedi Knight Sol journeyed to Brendok together with Master Indara, Master Kelnacca, and Indara's Padawan Torbin for the purpose of studying the planet's life. Brendok had previously been considered uninhabitable after being affected by the Great Hyperspace Disaster nearly a century prior, but it was now flourishing with plant life, which sparked interest from the Jedi Order. One evening during their study, Sol voiced his opinion that a vergence might be the cause of the life on Brendok, and that such a power deserved to be studied and protected. He assured a homesick and doubtful Torbin that their mission was a noble one.
The following day, as the Jedi continued their research, Indara discussed Torbin with Sol, noting that her apprentice was too distracted to fully appreciate the potential vergence. She also pointed out that they couldn't be certain that a vergence was present on Brendok. Sol believed that Torbin was disturbed and unbalanced, but Indara cautioned Sol against projecting his own feelings onto Torbin. Indara reassured Sol that this was the reason why she had a Padawan and he did not.
Indara instructed Sol to continue his exploration, using a speeder bike to follow a river leading to the planet's unexplored Northlands. There, he discovered a bunta tree surrounded by Brendoki flutterbies, as well as a far more astonishing discovery: two human girls, the twins Mae-ho Aniseya and Verosha Aniseya. Sol concealed himself in the trees, observing the girls as they argued and watching as they were led away by their mother Koril. Now aware that they were not alone on Brendok, Sol contacted Indara via his comm unit.
Sol continued to follow the woman and the girls all the way to their fortress, which Sol was unable to access through the main entrance. By scaling the fortress's outer wall, Sol secretly entered the catacombs and witnessed part of a lesson being conducted by Mother Aniseya. Sol watched with great concern as the woman used the Force to attack the two girls, causing them to fall back, and then repeating the action while instructing the girls to block. Sol also saw the witches making preparations for the Ascension ceremony.
Sol reported back to Indara, believing that he had discovered a Force cult of witches. Although Indara remained skeptical and wanted to seek guidance from the Jedi High Council, Sol urged her to take action, as he was concerned for the safety of the girls. He believed that the girls might be in danger from the ceremony that was to take place that night, and he insisted that Indara come and see what he had seen. The four Jedi then made their way to the fortress, bypassed the door's security, and entered as a team at Sol's insistence.

The four interrupted the women's Ascension ceremony, entering the fortress's courtyard. After Indara and Aniseya exchanged greetings filled with thinly veiled animosity, Osha finally emerged from the crowd at Indara's request. Sol knelt down and introduced himself to Osha, but he recoiled when her sister Mae revealed herself; the other girl had been branded with a marking on her forehead that had not been there that morning. After revealing that he had been spying on them, the witches became hostile, with Koril threatening Sol. However, Sol asserted that the Jedi did not take children. Sol unclasped his lightsaber from his belt, and although Indara believed that Sol was preparing for violence, he instead gently gave the weapon to Osha for her to examine. Sol asked Osha if she would like to be tested as a potential Jedi Padawan, believing that she would be a good fit. At that moment, however, Torbin fell to his knees, having fallen into a trance induced by Aniseya. Aniseya demanded that they leave so that Torbin could be returned to his right mind. Osha insisted, however, that she be allowed to take the Jedi's test. Aniseya released Torbin and told the Jedi that scouts would bring Osha to the Jedi camp at midday, but Sol insisted that they bring Mae as well. The Jedi then left as Indara thanked them for their cooperation.
Back at the Jedi ship, Indara commended Sol on his idea to test the girls, as she believed he did so to buy time to consult with the Council. However, Sol's offer was genuine, as he felt a connection to Osha and believed that she was destined to be his Padawan. Indara asserted that they could not take the test seriously and that the coven would not allow the girl to leave. Sol insisted that Osha could be in danger and may have resisted being marked like her sister, believing that she wanted to leave with the Jedi. However, Indara remained skeptical and warned her colleague not to confuse Osha's wishes with his own, similarly to Sol's thoughts about Torbin.
As agreed, the witches brought Osha and Mae to the Jedi's camp the next day. Mae was to be tested first, but she resisted, intentionally failing to accurately divine the images that appeared on Sol's testing screen. Indara asked Mae many questions, particularly about her marking and Ascension; Mae revealed that she was meant to one day lead the coven, but she was unsure how she and her sister could do so as children. After Mae was dismissed, Sol determined that she had been instructed to fail, and Indara gave him approval to try another technique with Osha. Osha also identified the images incorrectly, but she inadvertently revealed that she could see them clearly. Sol asked Osha what she wanted, not what her family wanted, and he revealed that he was even younger than her when the Jedi tested him. Sol emphasized that the Jedi believed he was special, just like Osha, and that while he was scared to leave his family, he found comfort in the many other children also at the Temple. He pushed for Osha to have the courage to say what she wanted and tell the truth, and Osha expressed her desire to be a Jedi. The Jedi continued the test, which Osha passed.
Later that night, Indara told the team that the Jedi Council would not approve of separating the twins from their coven or bringing them to Coruscant to be trained as Jedi. Sol implored that Indara could also feel that they weren't safe and insisted that he talk to the Council, but Indara maintained that they had already made their decision. Indara warned Sol not to alter Osha's destiny because of his emotional attachment to her, but Sol denied that was the case and stated that he only wanted to do what was best for the girl. When Torbin announced the twins' blood test results, they revealed that the girls' M-count was very high, but that they also shared the exact same symbionts. Sol interpreted this to mean that the twins were possibly created artificially, with a vergence used as a power source. Upon this revelation, Torbin took off, hoping to use the girls as proof of a vergence in order to end the mission and return to Coruscant.
Sol followed Torbin in the other speeder, while Indara and Kelnacca followed them both with their ship. Sol and Torbin found the fortress locked down, and they decided to climb the fortress walls and retrieve the girls. Sol warned Torbin not to let the witches inside his head again. The two Jedi entered the fortress's courtyard, where they confronted Aniseya, Koril, and a group of witches armed with bows. Sol assured them that the Jedi came with noble intentions and asked how the twins were created. However, Aniseya told Sol that one day the Jedi's noble intentions would destroy every last one in the galaxy. At that moment, Mae ran into the courtyard, pleading with her mother for help. Mistaking the girl for her sister Osha, Sol called out to her. Having finished with the Jedi, Koril readied her stance to attack Torbin, and Aniseya moved to protect her daughter, shrouding both herself and Mae in black smoke. Fearing for the girl's safety, Sol drew his lightsaber and stabbed Aniseya in the midsection before she could complete her transformation. Fatally wounded, Aniseya clutched Sol's shoulder, letting him know that she was going to let Osha go with them, assuring him that it was what Osha wanted.

As Aniseya fell dead, the other witches attacked Torbin, and Koril wielded her staff against Sol. Unmotivated to fight, Sol was struck by several blows and blocked or deflected others. Eventually, he bisected Koril's staff with his lightsaber and told Torbin that they needed to retrieve the girls as a fire began to consume the fortress. Koril vanished into black smoke and warned the two Jedi that they should not have brought "him" there. Although Torbin warned that his mind was fortified, Koril did not mean him, and the two turned to face Kelnacca, who was now under the witches' spell. Both Sol and Torbin defended themselves, barely withstanding Kelnacca's heavy attacks. When Kelnacca pinned Torbin against a wall, Sol grappled with the Wookiee to save the Padawan. Sol managed to land a strike that disarmed Kelnacca but succumbed to his strength, getting caught in a chokehold before Indara arrived to break Kelnacca free of the spell. The backlash of the mind-thrall spell being suppressed killed the witches who were making the Wookiee try to kill his team. Indara commanded Sol to find the twins.

Sol located the girls in a cavern that housed a massive power generator. As the generator exploded, it destroyed part of a bridge, leaving the two girls suspended above a deep chasm. As the bridge's halves began to buckle, Sol used the Force to hold them upright, but he could not hold them both for long. Ultimately, Sol decided to concentrate his power on saving Osha, allowing Mae to fall. Sol grabbed Osha before she could fall, bringing her back to the Jedi ship.
As the Jedi team departed for Coruscant, Sol watched over Osha as she rested. Indara reminded Sol and Torbin that she had told them not to interfere, although Sol expressed his only wish, which was to keep the girls safe. He asserted that he had to make a choice, and the two masters argued, stopping Torbin's distress as he asked what they were to tell the Council. Indara decided to settle on a partial truth for their story: that Mae started a fire and everyone but Osha was lost. Sol wished to face the Council with the truth, but Indara denied him, as doing so would take away Osha's dream of becoming a Jedi. Indara told Sol to ask himself why he made the choice that he did. As Osha reawakened in a fright, calling for her mother, Sol comforted her, giving Osha the incomplete story with Mae as the one responsible for her family's death. He assured her that there was nothing back on Brendok, but that they would be safe on Coruscant and that she could train as his Padawan if she wished. Sol promised the girl that she would never feel such pain again.
For a decade, Osha trained as a Jedi under Sol's guidance as a devoted Padawan. However, Osha was unable to master her negative emotions, including her grief over her mother and her hatred for her sister. Eventually, Osha left Sol and the Jedi Order altogether. Sol thought about Osha often, and his biggest regret was his inability to help Mae, although he always believed in the decisions he made on Brendok and made peace with what happened.
After Osha, Sol trained Jecki Lon as his Padawan and taught other younglings in the Jedi Temple as a respected Jedi Master.

In 132 BBY, Master Sol was informed of the murder of Master Indara, and he was saddened to learn that she had met such a violent end. Some time later, Sol held a lesson with many Jedi younglings, asking them to close their eyes and feel the Force. The younglings described feeling life and balance, although one youngling saw a fire that consumed everything it touched. Sol taught that the Force was powerful, like fire or an ocean, and that its power must be respected. Master Vernestra Rwoh, Sol's colleague and friend, entered at the end of the lesson. She told Sol that his students were lucky to have such a compassionate teacher, and she reminisced about when Sol was small, although Sol felt lucky to be taught by the younglings. Rwoh had come to discuss Indara's murder, as his former Padawan, Osha, was in custody as the prime suspect. Sol was baffled, as he believed that Osha was nothing but a devoted Padawan who saw the Jedi as her protectors. Sol agreed with Rwoh that the investigation should not become public, as news of a murder by a former Jedi could be used by the Jedi's political opponents, and he assured her of his support, although he was disturbed.
Later, Sol's Padawan, Jecki Lon, met with her master, and she saw him looking at a hologram of Osha in her Jedi robes. She informed her master that Rwoh had requested Sol's presence at the detainment level, and after asking to speak freely, she asked why Sol kept holograms of his former Padawan, warning that such a pastime encouraged sentimentality and nostalgia. Sol told Lon that memories were lessons, and that the past should be meditated on so as not to repeat it.

Sol met Rwoh at the detainment level, which was holding a large group of prisoners who had mutinied and escaped their transport over Carlac. Osha, who had been on the ship, was not among the survivors. Sol approached a lone man in a cell who was muttering about Osha's "darkness." He cleared the man's mind and asked what had happened. The man explained that Osha had helped him escape, but he betrayed her and took the transport's last escape pod. Sol requested permission to go to Carlac and bring Osha in himself, asserting that he could feel that she was alive. Although Rwoh did not want to lose Sol to a field mission, Sol wanted to take accountability as her former master if Osha truly was guilty. Rwoh granted him a small team for a discreet mission.
Sol included his Padawan, Jecki Lon, and Jedi Knight Yord Fandar, who was originally responsible for bringing Osha in, in his team. As they boarded their ship, the Polan-717 Jedi transport designated Polan GX-8, they greeted Fandar, who was steaming his robes. Fandar bowed, hoping for forgiveness and redemption on their mission. Sol reassured him with a friendly pat.
While in transit to Carlac, Lon asked Sol how well he knew his former Padawan. Sol gave Lon the incomplete story of the incident on Brendok, revealing that Osha had a twin sister. This surprised Lon and Fandar, as such information was not in her file, but Sol stated that Mae was surely dead, as he had watched her die. As Lon and Fandar prepared for landing, Sol contemplated silently.

The Jedi investigated the remains of the prison transport, doubting that there were any survivors despite evidence of someone having been there. Quickly sensing Osha's presence, Sol directed his team to follow him into a cave. At the end of the cave, they found Osha, who pleaded with Sol that she did not commit the crime. Osha slipped from an icy ledge, but Sol caught her with the Force. Reunited with his old Padawan, Sol smiled warmly, believing Osha's assertion that Mae was alive. Sol ordered Fandar and Lon to stand down, escorting Osha peacefully without restraints.
Back aboard the Polan, Fandar protested to Sol over not restraining Osha. Sol maintained that she did not kill Indara, as she had not trained in six years. Although Fandar suggested that Osha and her twin could be working together, Sol told Fandar not to let fear affect his judgement. In the ship's cockpit, Sol met with Master Rwoh over hologram, informing her of Osha's sister Mae. Rwoh agreed, as another incident had just occurred while Osha was in their custody: someone matching Osha's description had broken into the Jedi temple on Olega. Rwoh ordered Sol to continue investigating and to bring Osha, as she could be an asset.
En route to Carlac, Sol noticed Osha's tattoo on her arm, which consisted of two black mirrored parallelograms. She explained that she got the tattoo during a "crazy night" with her meknek crew in CorpSec, and she believed that Sol hated it. Sol laughed, saying that it didn't matter what he liked. The Jedi Master asked if Osha was certain that her sister Mae was behind Indara's murder. Osha was certain that it was the only explanation, and that she had to have survived somehow. Sol wished that he had been able to save them both, but Osha assured him that what happened that night wasn't his fault. Sol expressed that he had made peace with what happened on Brendok, and Osha lamented that she had never accepted what she'd lost. Osha stated that perhaps she wasn't a very good student, but Sol offered that perhaps he wasn't a very good teacher.

After landing on Olega, Sol and his team met with the Jedi of Olega's temple. The Jedi walked them through the events of the previous night, identifying Osha as the one who had snuck into the temple. Sol asked to speak to Torbin, and although Torbin hadn't spoken to anyone in over a decade, Sol was certain that he would speak with him, as he was an old friend. Sol's team entered the temple to find Torbin dead, with Osha standing over him. Yord, who had been watching Osha, cleared her of suspicion, and Sol examined Torbin's body. There were no signs of struggle, and Torbin had taken poison willingly. Osha explained that the poison was bunta from her home planet and must have come from nearby.
The Jedi watched over an apothecary, the only one in town, to try and locate the poison's source. Sol agreed to follow Lon's plan: to allow Osha to disguise herself as her sister and talk to the apothecary's supposed owner, Qimir, while recording the conversation. The Jedi listened as Osha entered the shop, where the owner asked Osha if the poison had worked, but Sol stopped the Jedi from acting just yet. The shop's owner expressed his delight at believing that "Mae" had killed Torbin without the poison, knowing that "he" would be so pleased. The Jedi swarmed the apothecary, and Sol told Qimir that they would consider letting him go with a warning if he cooperated. Qimir introduced himself simply as a supplier, and Sol asked if Mae had a master. Qimir claimed that all he knew was that Mae wanted revenge on four Jedi. Sol told Fandar to secure the perimeter; the team would wait for Mae, laying a trap for her when she returned to the apothecary that night.
After nightfall, Sol and Osha waited for Mae in an alley. Osha was adamant that she would confront Mae, although Sol wanted to face her alone. Sol was surprised that Osha was still so angry, telling her to let go of her grief, certain that she wanted revenge instead of justice. Sol told Osha to let him try to save Mae now, as he couldn't when they were children. Sol told Osha to have faith in Mae and himself, despite the fact that he was one of the Jedi that Mae was targeting.

When Mae finally showed up, Sol confronted her directly. Mae launched an acrobatic kick at Sol, but he effortlessly blocked it. They continued their struggle, with Sol calmly defending against each of Mae's intense attacks. Sol questioned why Mae attacked him unarmed, but she persisted, unsuccessfully attempting to seize Sol's lightsaber. Sol relieved Mae of her knives, explaining she misunderstood the Jedi way and inquiring about her trainer. Eventually, he used the Force to restrain her, discovering she didn't even know her master's identity. Sensing Mae's focus on her sister, Sol revealed Mae was alive. In disbelief, Mae tried to flee, but Fandar and Lon cornered her in the Polan. Despite Sol extending a peaceful hand, Mae used the Force to create a dust cloud and disappeared. Unable to capture Mae, Sol contacted Master Rwoh aboard the Polan. Sol wanted to continue the investigation, but Rwoh refused, preferring to strategize given the presence of a trained outsider, expecting Sol on Coruscant soon.
Upon his return to Coruscant, Sol participated in a small gathering of Jedi Masters, where they analyzed Mae and speculated about her master. Rwoh emphasized Mae's danger and her connection to Sol's past, convinced a Jedi had trained her. Rwoh chose not to inform the High Council, determined to uncover the trainer without public knowledge. After Rwoh tasked master Holden with intercepting Mae on Khofar, Sol approached Rwoh, begging to be the one to apprehend her. Rwoh questioned why he hadn't mentioned Mae's potential survival on Brendok, to which Sol admitted he believed it possible, having witnessed her apparent demise himself. Again, with other Jedi present, Sol pleaded to be the one to take Mae into custody. Rwoh refused, citing his personal connection to both Mae and her sister. Sol argued that Mae's objectives were not solely her own; Rwoh agreed, suggesting it was part of her master's larger plan to disrupt balance. Sol warned Rwoh that killing Mae would eliminate knowledge of her mysterious Master, believing Mae wouldn't surrender without something in return. Rwoh inquired if they possessed something she desired, to which Sol nodded in affirmation.
Later, Sol encountered Osha preparing to leave the Jedi Temple. Sol asked Osha to secretly join the Jedi on the mission, believing she could reach Mae. Despite Osha's reluctance, Sol was convinced Mae had affection for Osha, and the Jedi would allow both to go if Osha agreed. Sol emphasized their shared desire to protect Mae, believing in her inherent goodness. Osha finally consented, reluctantly wearing civilian robes.
As Sol's team, now larger with several Jedi Knights, landed on Khofar, they ventured into the perilous wilderness, using the Tynnan Bazil as their guide. Descending a mountain into Khofar's forest, they discovered a dormant umbramoth colony. When Osha touched one of the sleeping creatures, it awoke and attacked the Jedi. Sol swiftly killed it with his lightsaber, urging the Jedi to continue before nightfall.

After losing Bazil, the team pressed on. Osha assured Sol she could sense things again, giving her confidence to face her sister; Sol countered that they would confront their shared past. He promised a full explanation once Mae was safely detained. At sunset, the Jedi arrived at Kelnacca's shelter. The Jedi demanded Mae exit the dwelling. However, Sol sensed a dark presence approaching. A masked Stranger appeared behind Osha, drawing the Jedi's attention, refusing to stand down. The Stranger ignited a red-bladed lightsaber at Mae, prompting the Jedi to activate their own. Despite Sol's warning for Osha to flee, the Stranger used the Force to throw her aside. The Jedi advanced, led by Sol, which the Stranger countered with a powerful Force push that sent them flying.
The Stranger killed many Jedi on Sol's team, skillfully using his lightsaber and disabling theirs with his helmet. When Osha regained consciousness, she fled into the forest, where the Stranger eventually found her. As the Stranger moved his lightsaber to strike, Osha ran, and Sol intervened, deflecting the blow. As Sol, Osha, and Fandar faced the Stranger, Sol ordered Fandar to escort the "civilian" to their ship, using the Force to push Osha away. The Stranger recognized Sol, who questioned the Stranger's identity, sensing familiarity. They dueled, their blades clashing among fallen trees. Sol asserted that despite wielding a Jedi weapon, the Stranger was not a Jedi. Sol demanded he reveal his face, questioning what kind of master would hide from his pupil, though the Stranger claimed he had something to hide from his pupil as well and stated his mask was a needed form of mental protection. After a brief continuation of the duel, the Stranger vanished.

The Stranger pursued Mae through the forest, who escaped Lon's restraint. Sol and Lon attacked the Stranger, preventing him from killing Mae. After the Stranger disabled Sol's lightsaber with his helmet, Sol struck him, sending him backwards, giving Lon an opportunity to attack. Lon shattered the Stranger's helmet with elbow strikes, but when she charged for another attack, she was stabbed three times in the chest with the Stranger's secondary lightsaber. Sol reached for his Padawan, sadly calling her name, lamenting her youth. The Stranger, revealed as "Qimir" from Olega, blamed Sol for her death. The Stranger blinded Sol with his cloak pulled Mae towards him with the Force, to which Sol answered with a lightsaber attack, which the Stranger readily deflected. As the Stranger put his saber to Mae's head, Sol tossed his own saber to the side. Sol asked the Stranger again who he was; the man claimed to have no name, but that the Jedi might call him a Sith. The Stranger claimed to want the freedom to wield his power the way he liked without having to answer to the Jedi. He wished for an acolyte, but now that Mae had him exposed, he was determined to kill every single last Jedi who had seen his face, claiming the Jedi made the rules.

Suddenly, Fandar reappeared, summoning the Stranger's helmet and ambushing the Sith. Though both of their lightsabers became disabled, the Stranger overpowered Fandar and broke his neck. Mae attempted to run, but Osha stunned her. Sol charged the Stranger, exchanging blows with his enemy but soon overwhelming him with strikes. Besting his opponent, Sol sent the Stranger flying with a kick, then readied his saber for a decapitation strike. Before he could kill the Sith, however, Osha stopped him with a shout. Restrained, the Stranger wondered why Osha still trusted Sol after everything he had done to her. Sol asserted that the Stranger's mind was twisted by darkness, but the Sith claimed to have accepted his darkness, asking what Sol had done with his own. Sol withdrew his weapon, holding that the Jedi did not attack the unarmed. Before the Stranger could attack Sol again, Osha detached the head of her PIP droid, sticking it to the Stranger's back to attract the umbramoths, who carried him out of sight. Now safe, Osha asked Sol why the Stranger would say she couldn't trust him. Sol once again promised to explain himself, but Mae reappeared, summoning Osha's stun gun and stupefying Sol with a stun blast.
Awakening after sunrise, Sol was greeted by "Osha," who was actually Mae wearing her sister's civilian robe. "Osha" told Sol that her sister was gone and Sol sadly surveyed Lon and Fandar's bodies before leaving. The two boarded the Polan with Bazil and departed the planet.
As the Polan left Khofar, Sol tried to contact the Jedi Temple. He reached Padawan Mog Adana, and despite the poor connection, Sol managed to report his entire team was dead. Unable to get a strong signal, Sol went to fix the transceiver, telling "Osha" to pilot the ship. As Sol retreated into the ship's foyer, he paused to mourn his fallen comrades and Padawan, looking around as if they were still present. Returning to the cockpit, Sol hugged "Osha", thanking her for saving him and lamenting that the Stranger had corrupted Mae. Sol apologized said that it was time to make things right and face the High Council concerning everything that had happened on Brendok. Just as Adana came back through on the transceiver, the ship shut down. Sol sent "Osha" to investigate the problem.
Osha returned to the ships darkened foyer and informed Sol that the system was resetting. Quietly reflecting, Sol wondered how he couldn't have sensed the Stranger's true intentions when he met him as "Qimir" on Olega. Sol also noticed that "Osha" had recovered the PIP droid, noting how she had always loved the droid although he was just a machine. "Osha" told Sol that even if she didn't know it at the time, she had to lose a lot of herself to become a Jedi, and told Sol that he could tell her everything that happened on Brendok now that she wasn't young anymore. When the ship's systems turned back on, "Osha" rushed to the cockpit to communicate with the Jedi, but Sol stunned her. He shut down the ship's responder despite the imminent arrival of the Jedi and jumped to hyperspace.
Sol restrained Mae to a bed, assuring her he would not harm her when she awoke. Sol told Mae that they had much to do, including finding Mae's master and saving Osha, but that first they were going to talk; Sol had sixteen years to think about what he would say to her if he could, and implored Mae to listen, telling her the full story of what happened on Brendok.
When the Polan exited hyperspace, Sol told Mae they were at Brendok and the Jedi would meet them there. Sol hoped to prove the existence of Brendok's vergence now that Mae and Osha were both alive. Mae demanded why Sol lied to Osha and blamed the coven's destruction on herself. Both Mae and Sol defended their own actions, and Sol expressed that his biggest regret was that he couldn't save both girls. Sol believed that Mae and Osha weren't twins or even sisters, but before he could finish, Mae stunned him and ran to the Polan's secondary escape ship, telling Sol she would see him in hell. Sol pursued Mae into Brendok's planetary ring, where he nearly intercepted her, but Bazil dismantled wiring in the ship's hull, causing the Polan to ram the escape ship and send it crashing to the surface.

After landing on Brendok, Sol entered the abandoned witches' fortress, hearing echoes of the past. He wandered through the dark catacombs and eventually encountered the Stranger. The Sith thanked Sol for leading him back to Mae, saying they made a great team, and ignited his lightsaber to attack the Jedi. They dueled intensely, fighting outside on a bridge and damaging the metal barriers with their lightsabers. They floated down from the bridge, and Sol voiced his determination to destroy the Stranger if necessary. The Stranger, splitting his saber into two, said Sol wouldn't if "she" got to him first. They continued to battle, with Sol repeatedly gaining the upper hand, using his lightsaber skills to outmaneuver the Sith, disabling him with kicks, and using the Force to send his dual lightsabers flying away. As the Stranger reassembled his lightsaber and continued their duel, they noticed a Jedi ship descending. Sol was determined the Stranger would pay for everything he'd done, but the Sith was certain the Jedi weren't coming for him. They dueled again, locking and clashing sabers fiercely, but with a final swing, Sol cut through the hilt of the Stranger's lightsaber, ending the fight. The Stranger accepted defeat, removing his helmet to face Sol's blue blade.
At that moment, Mae ambushed Sol, disarming him and taking his lightsaber. The Stranger urged her to embrace her anger and strike Sol down to complete her journey. Mae refused, wanting Sol to face justice and admit his crimes to the Jedi Council, the Senate, and the Republic. Sol tried to defend his actions, discussing Mae and her sister's origins and the need to protect them. Sol explained his belief that Mother Aniseya had great power and used the Force and the vergence to create the twins, a power very few had held in the history of the galaxy. At Mae's insistence, Sol admitted to killing Aniseya, which Osha, who had just arrived, witnessed, asking if it was true. Sol maintained it was the right thing to do, explaining that he didn't tell the Jedi as there was no way to prove the vergence without Mae and didn't tell Osha as the Jedi wouldn't allow her to be trained. Sol pleaded that he wanted to tell Osha so many times, but couldn't. Osha told him to stop talking, brandishing his discarded saber. Sol continued speaking, claiming to have done everything so that Osha could have the life she dreamed of. Before Sol could finish his next sentence, Osha held Sol in a Force choke, slowly choking the life from him. In his dying moments, Sol told Osha that it was okay, accepting his fate and falling dead at the feet of his old Padawan.
Immediately after Sol's death at Osha's hands, Osha fell to her knees in horror, inadvertently bleeding Sol's lightsaber crystal and turning the blade red. Master Rwoh and a team of Jedi Knights soon found Sol's body in the fortress courtyard. The Jedi didn't find the Stranger or the twins, Rwoh apologized to her friend and gave Sol a Jedi funeral, burning his body on a pyre in one of Brendok's lakes. Osha returned to the world inhabited by the Stranger to train as his new Sith acolyte, now fully disillusioned with the Jedi way.

Rwoh returned to Coruscant and represented the Jedi Council at a Senate tribunal. While there, Rwoh would frame Sol for the murders of Indara, Torbin, Lon, Fandar, and all the others committed by Mae and her Sith master. In doing so, the truth (as far as it was known) of the Brendok incident was kept under wraps, though Sol's legacy was forever tarnished. Later, Rwoh would meet with Mae, whose memories of her sister and her tutelage under the Stranger had been wiped. Rwoh explained that many of the events in Mae's life occurred due to the selfish actions Sol tried to justify with the love he had for her sister Osha. The Jedi Master asked for Mae's help in locating the Stranger, who was a pupil of Rwoh's before he turned to evil.
Sol was a human male, his hair was worn normally down to the base of his neck, with a single lock held together with a thread, he wore the typical colors of the Jedi of the High Republic and during the missions he wore the typical brown tunic of the Order, during the mission on Brendok, his hair was shorter and more shaggy.
Sol was a kind, brilliant and compassionate man, as well as a good teacher, he believed in people, so much so that he immediately distrusted the idea that Osha had killed Indara and tried in every way to arrest Mae peacefully. However, Sol also had a dark side, he was impulsive, hasty and reckless. Although he was moved by the best intentions, his methods, at least during the mission on Brendok, were questionable, when he discovered that mother Aniseya had used a vergence to create the girls, he decided to take them against the will of the coven and against the will of the Jedi Council itself, after saving Osha, Sol showed minimal remorse, claiming he had to make a choice, when he discovered that Mae was alive he did everything to be sent with Osha to search for her, and risked his life trying to capture Mae. Sol didn't accept what he had done on Brendok trying to justify it as an "accident" and blaming Mae for causing the fire. In the end, however, he admitted his mistakes and agreed to pay with his life, being killed by Osha.
As a seasoned Jedi Master, Sol possessed a wide array of Force abilities, such as using a mind-touch to alleviate a convict's fear and facilitate communication. This Jedi could also employ telekinesis in various ways, from opening doors and saving Osha by Force-pulling her from a fall, to catching Mae in a Force hold during an attempt to capture her. Furthermore, he could extract information from her mind regarding her teacher. Following this, Sol sensed her feelings for her sister and tried to use them to convince her to surrender. He was also a skilled warrior, able to defend against Mae's barrage of blows without drawing his own weapon and successfully disarming her of her knives.

He could sense Kelnacca's approximate location on Kohfar and could easily dispatch an umbramoth with his saber. However, when the Master attacked him with a Force push, he was flung back with the rest of the Jedi in his squad. Sol fought the Sith wearing a mask, who admitted the piece of armor was all that was keeping Sol from reading his mind. The Jedi was coming out worse in their duel, until, furious after the butchering of his Padawan and with both sides unable to turn on their sabers, Sol charged the Sith and briefly subdued him in unarmed combat.
During the mission that led to finding Osha, he felt he sensed that he was in somehow destined to take Osha as a Padawan. During the third time he came to the witch compound, he demonstrated the power to see things from afar after a few moments of focus. When he thought he was under attack from Aniseya as she invoked her powers, he swiftly drew his blade and cut her down, then when Koril assailed him, he endured her punches and caught her spear, before breaking it with his saber. Despite his skills with a blade and using the Force to leap around, and even disarming his attacker, he was unable to defend himself when a Wookiee Jedi was taken over by the coven and impelled to attack him, only being saved when Master Indara broke the spell. Sol found the twins on a collapsing bridge and used his will to try to keep them from falling, but though he franticly strained himself in keeping them aloft, he was not powerful enough to save both, so chose Osha.
Sol was stealthy, able to follow three witches, infiltrate a dark side cult's stronghold, observe them using the Force on younglings, see them conducting a ritual, and escape without being spotted and barely being sensed by Koril. The Jedi also was a strong climber scaling the walls of the Brendon fortress and returning to his friends, then quickly clambering up again when he returned following Torbin.

Just before his final battle on Brendok, he sensed Mae was somewhere in the witches' old lair. When he traversed the old battlefield, the Jedi Master heard the echos of the destruction of the witches. Upon being ambushed by the Master, Sol clashed blades with the Sith and landed several unarmed hits, while using the Force to leap off a bridge and around his enemy. When Quimir lost a lightsaber, Sol attacked him so quickly that the Sith's effort to use the Force to reclaim the hilt failed. During the battle he used a Force-charged kick that sent the Sith falling back. At one point, he used his lightsaber to deflect the Sith's thrown lightsabers and as the Sith used the Force to pull the weapons back, Sol knocked them away from him and blasted the darksider down. Finally, after a grapple, he was able to destroy the Stranger's weapon with his own saber and capture him, but just as victory crystalized, Mae stole his weapon and harassed him into confessing he had slain her mother. Sol broke down as he explained his justification and offered no resistance as Osha compressed his neck.
Sol was a capable pilot, flying a Polan-717 Jedi transport on various missions and was able to operate a speeder bike.
Like many other Jedi Masters during the High Republic Era, Sol wore opulent white robes with a golden trim and a yellow tunic while in the temple. He also wore a brown cloak and a belt with the insignia of the Jedi Order along with brown gauntlets while on missions.
Sol wielded a single blue-bladed lightsaber.
Sol was created for the 2024 Disney+ live-action series The Acolyte. Lee Jung-jae played the character. According to Leslye Headland, she wrote the character of Sol while the Netflix show Squid Game, where Lee Jung-jae was portraying the character Seong Gi-Hun, came out in September 2021. While watching, Headland remarked "that's Sol," and that he ran the gamut of every single emotion. Before Jung-jae's casting, Keanu Reeves was courted to play Sol, but had scheduling conflicts with Len Wiseman's 2025 film From the World of John Wick: Ballerina, as Reeves was unable to adjust his shooting schedule during filming of the John Wick spin-off to accept Lucasfilm's offer.
The episode "Teach / Corrupt" is unclear whether Sol can see through Mae's disguise. The StarWars.com article "The Acolyte Explained | Highlights from 'Teach / Corrupt'" suggests that Sol was so grief-stricken or clouded by attachment that he was unable to recognize Mae, however it also states that he did identify Mae and was playing the long game. The This Week! in Star Wars Dispatch episode "Many Unknowns" also states that "an undercover Mae doesn't fool Master Sol for long." However, the Star Wars Insider 229 article "Star Wars: The Acolyte: Companion" says Sol did not recognize Mae until Bazil warned him.
