In the early days of the Mandalorian aggression that would culminate in the Mandalorian Wars, Juhani narrowly escaped the genocide of her people by the forces of Mandalore the Ultimate's lead strategist, Cassus Fett, in the Battle of Cathar. When Cathar capitulated, her parents fled the planet among the very last remnants of their race, taking their child with them; they fled as far as they were able, and eventually settled on Taris. It was there that Juhani, only a few months old, was raised; throughout her life, she called Taris her homeworld.
Like many non-Humans on Taris, at that point in its history, Juhani's family had a rough life. The native Humans disliked them merely for being "aliens," looked at them in disgust, persecuted them, and charged them more for food than their own species. Juhani had mixed feelings for the planet she had to live on; she hated it, called it a "rat-hole" and a "warren," but still felt that it was her home and that her life could have been far, far worse.
In 3,963 BBY the Mandalorians finally entered Republic space, and Taris fell under siege. Xor, a Twi'lek who had fought with the Mandalorians on Cathar, provoked Juhani's father into a fight and killed him. Her mother escaped with Juhani, but with the death of her mate something began to slowly die within her as well. She worked as hard as she could, but still didn't earn enough money to support both herself and her daughter. So she started borrowing money from the Exchange, doing everything possible to save funds, and giving Juhani most of their food. She began to waste away, until one day she collapsed in the cantina she worked in and never recovered, as they simply did not have enough money to pay a doctor.
The Exchange was the major supplier of slaves on Taris, and when her mother died they charged Juhani with her mother's debts and enslaved her, as she had no way to repay them. This was the worst period in her life. She was bound like a beast and treated like livestock, until she was released by a Jedi before she could be sold to her father's murderer, who was going to purchase her at auction.
Juhani never gave up hope for a better life, however. She had heard tales about the Jedi, and had somewhat idealized their image as "champions of truth, defenders of justice, heroes of the Republic." When she was freed from the slavers by Revan, who came to fight the Mandalorians with his group of Jedi, he and those Jedi lived up to everything her imagination had created them to be. Encouraged by one of Revan's followers to join the Order, Juhani vowed to become a Jedi, and because she was Force-sensitive she had the potential.
"From that moment on I knew that I would have to try to become a Jedi. To lift myself out of the rut I had been living in for years and to make a real difference, as the Jedi were. The foolish delusions of a child. But THIS child made it happen!"
As soon as she collected enough money, she boarded the first freighter to Dantooine, where she was taken for training by Jedi Master Quatra. Juhani progressed, but she was ever struggling with her Cathar blood, which gave her a difficult time mastering her emotions, so sometimes she doubted her place among the Jedi.
She confided her doubts to Dak Vesser, a Padawan who joined the Order at the same time as she did, and who had doubts of his own. When Dak decided to leave the Order, he surprised Juhani by confessing romantic feelings for her, and he asked her to come with him. Juhani did not return his feelings and Dak grew angry and left the Jedi Enclave, eventually joining the Sith on Korriban.Juhani remained with the Jedi and came through with her training, until Quatra decided it was time for her to face the Jedi Trials. Quatra had nothing left to teach her but Juhani had yet to learn to accept her own limits, so it was her choice to test Juhani in an unusual way, by allowing her to give in to her rage and strike her down in the middle of a fierce confrontation. Quatra was greatly injured and feigned death.

Believing that she had harnessed the power of the dark side, Juhani left the Enclave and hid in an ancient grove where Jedi used to meditate. The grove soon became tainted, and the local kath hounds became more aggressive, resulting in attacks upon the settlers.
Three years earlier, much to her incredulity, her hero Revan had come back a Dark Lord of the Sith. Later on, Bastila Shan was key figure in the capture of Darth Revan, and Revan was said to have died. Over Taris, the Sith set an ambush for Bastila and eventually destroyed the planet as a means to ensure she wouldn't escape. With the help of a Republic soldier, Bastila was able to return to Dantooine and report to the Dantooine Enclave Council, who then accepted to train her companion in the ways of the Jedi. When Juhani was ready for her own Jedi trials, the new apprentice had almost made his way to the title of Padawan, the last test being the cleansing of the grove that Juhani had tainted. The Force-sensitive soldier was really Revan, learning once again the ways of the Force after his mind was destroyed. A new identity had been created for him through the Force by the Jedi, so that Bastila could draw on his subconscious memories to lead them to the Star Forge, the seat of power of the former Dark Lord.
As Revan approached the grove, Juhani engaged him in battle and was defeated. Having bested her Master, she did not expect he could match her power, but then she realized what Quatra had tried to teach her: Humility. She tried to teach her that even one who is true to the teachings of the Jedi may just as easily fall to the dark side by their inability to understand or accept their own limitations.
Revan spared her life and persuaded her to ask the Jedi Council for mercy. Juhani returned to the Enclave and learned the truth about Quatra, who had already left to train other students, confident that Juhani would pass the trial. She felt foolish then to have thought she could harm a Master such as Quatra, and though she still bore the scars of her slip to the dark side, she trusted her Master's wisdom and now truly understood what she was meant to learn. With this final trial passed, Juhani was promoted to the rank of Jedi Knight.
When Revan and Bastila uncovered the Star Map in the Rakatan Ruins of Dantooine and were appointed the quest to find the Star Forge, Juhani asked the Council to accompany the Padawan, of whom she could not know the true identity, as she had never seen his face. Feeling she would perhaps serve as a reminder to Revan of the dangers of an all too familiar path, the Council granted Juhani's request and she joined the crew of the Ebon Hawk.
The Jedi Civil WarEdit
"We WILL defeat Malak and save the Republic from the Sith threat once and for all!"
―Juhani, on the Temple of the Ancients[src]
During their travels, Juhani opened up to Revan about her past. When she revealed her homeworld had been Taris, she lashed out at him in anger, but then calmed herself with the Jedi Code, and realized that nothing could have been done to prevent Taris' destruction.
After being captured by Saul Karath and running into Malak (and the subsequent capture of Bastila), Revan revealed the shocking truth of his true identity to Juhani and the crew. Juhani expressed her strong opinion that Revan could never have truely changed, and vowed that now - from his example of redemption - that she would never fall to the dark side. Little did she know that her vow would be put to the test.
During her time with Revan, Juhani was lured by the dark side again. While travelling in search of the Star Maps, she encountered Xor, the Twi'lek slaver who had tried to purchase Juhani on Taris during the Mandalorian Wars. The old slaver tried once again to purchase her, making his offer to Revan. Revan stood by her, saying she was her own person; Juhani lashed out at Xor as he spoke of how he wiped out her people on Cathar and killed her father on Taris, but she did not give in to her anger and let him go, though the thought of him still running free made her Cathar blood seethe. Xor promised he would be back and he did, with two enforcers, intent on taking Juhani by force.
The second time they encountered Xor, he and two of his thugs were beaten; Xor chose to use his last moments to feed her hatred, so as to have the satisfaction to show Juhani she was no better than him killing a defenseless opponent. Juhani regretted he did not die by her hand, but with Revan's support she was able to leave Xor to his inevitable fate, even as he related the burning of the people of Cathar in their homes by his hand and the pleasure he took from it. Generally, Juhani showed the most zeal as an advocate of the light side and the ways of the Jedi; perhaps to show her repentance and restrain herself from falling anew.
Juhani repaid Revan in turn when they were stranded on Lehon. Revan had collected the five Star Maps he needed to locate the Star Forge, but as the Ebon Hawk approached the space station, a disruptor field damaged its hyperdrive and the ship barely made it to the nearby planet without joining the wreckage that covered the surface. Juhani suggested to search the other downed ships for the parts the Ebon Hawk needed to take off, but the disruptor field still needed to be deactivated. The possible whereabouts of its generator was found by the droid T3-M4, which detected energy readings on the ship's sensors that seemed to be coming from the Temple of the Ancients. The Elders granted Revan access to the temple, but tradition had it he should go alone; however, when both Juhani and Jolee Bindo received a premonition warning them of great danger laying inside, they insisted on accompanying Revan and struggled to persuade the Rakata to allow them to. It turned out to be the right decision, as the temple was infested with numerous Dark Jedi, Sith Masters and acolytes.
Atop the temple, they were confronted by Bastila, who had been tortured and turned to the dark side by Darth Malak. When she found herself at a disadvantage, the fallen Jedi made a good case luring Revan to reclaim his usurped title of Dark Lord of the Sith, but Juhani and Jolee helped him resist and were possibly critical in Revan's choice to turn his former self aside for good. Juhani had saved the man that had saved her; Bastila mocked Juhani for running like a cowering animal when she first touched the dark side. After the death of Malak and the destruction of the Star Forge, Juhani was honored at the celebration of the Republic's victory on Lehon along with Revan and his other comrades.
