Jaina Solo is the daughter of Han Solo and Princess Leia Organa Solo. She had a twin brother named Jacen Solo and a younger brother named Anakin. She had relationships with fellow Jedi Zekk and married Jagged Fel.
In their early years the Solo twins were targets of many kidnapping attempts, so they spent a lot of time in hiding. Because of the political duties of their mother, Winter and C-3PO looked after Jaina and her brothers. Like her mother Jaina Solo was Force- sensitive but in the beginning utilization of the Force was only allowed to her under the supervision of her uncle Luke Skywalker. Never the less Jaina and Jacen used their abilities on several occasions. For example when they saved their uncle from the spirit of an evil Sith Lord named Exar Kun.
When she was fourteen, Jaina started her training as Jedi in Skywalker's Praxeum on Yavin 4. During this time she discovered her inherited mechanical aptitude and became a capable pilot. The twins made friends with Chewbacca's nephew Lowbacca, a girl named Tenel Ka Djo and boy called Raynar Thul. Together the group of Jedi trainees played a major role in the defeat of the Shadow Academy, the destruction of the Second Imperium, the collapse of the Diversity Alliance and the annihilation of a hidden spice cache in Crystal Reef.
After her time on the Jedi Academy Jaina became the apprentice of her aunt Mara Jade Skywalker.
Yuuzhan Vong War
When a warlike species from another galaxy tried to overpower the reformed New Republic by using their advanced biotechnology and their strategic skills Jaina fought along the other Jedi to end the war. Jaina joined the military and constantly was on the front lines of battle as a Rogue Squadron pilot. Because of her great skills she became known under many titles.
While the New Jedi Order called her "Sword of the Jedi" and the Rogue Squadron pilots nicknamed her "Sticks", and she was refereed to as the "Trickster Goddess, Yun-Harla" by the Yuuzhan Vong invaders. The death of her younger brother Anakin, who died during the "Mission to Myrkr" caused her to walk very close to the Dark Side of the Force, but with the help of Jedi Knight Kyp Durron, who became her new master, she was redeemed.
She flew in the Battle of Dubrillion, participated in the defense of Ithor, slew the Warmaster Tsavong Lah and discovered a way to use the enemies warships tor the Republic's advantage. She also became romantically involved with fellow Chiss pilot Jagged Fel. Even after the war Jaina spent her time by capturing thirty-seven warlords and breaking over hundred smuggling rings.
Like many other surviving Jedi of the "Mission to Myrkr" Jaina later became Joined into the Killik community, an insectoid hive species who lived on the edges of known space. She played a major role in the Dark Nest Crisis and the following war against the Chiss, which strained her relationship with Jagged Fel.
Second Galactic Civil War
When the Galactic Alliance was at war with Corellia, Jaina fought in the battle of Tralus, assumed control of Harpoint Squadron and later she commanded the Rogue Squadron with her brother Jacen during the Blockade of Corellia. Unfortunately her brothers increasingly aggressive actions resulted in a schism between the two siblings. Jaina was the first, who noticed Jacen's Dark behavior and suggested that his Jedi apprentice Ben Skywalker should be given to a new master.
After the Correlian crisis, Jaina was teamed up with Jagged Fel and her childhood friend and fellow Jedi Knight Zekk to track down the Dark Side Jedi Alema Rar. During this partnership Jaina was very confused because both men were interested in her. While she was tracking the Dark Jedi, her aunt Mara Jade Skywalker tried to handle a Sith named Lumiya, but was killed by Jaina's brother Jacen, who had fallen to the Dark Side.
As a result Jaina focused all her effort on stopping her brother, who now called himself Darth Caedus. After training with her father's ex-arch-enemy Mandalore Boba Fett, and with the help of her uncle, Grand Master Luke Skywalker she was finally able to kill her brother in a lightsaber duel aboard the Star Destroyer Anakin Solo.
Fate Of The Jedi
After the death of Darth Caedus, Luke Skywalker was forced into exile by Chief of State Natasi Daala because he hasn't prevented Jacen Solo's fall to the Dark Side. Jaina organized an informal organization called Darkmeld to watch out for other renegade Jedi and to undermine Daala's efforts to monitor the Jedi. At the same time Jaina had to reject a marriage proposal by Jagged Fel, because it would meant that her loyalties would be split between him and the Jedi. Some time later they reconciled their relationship and accepted their mutual needs to keep secrets from each other.
Around the same time Jaina participated in a mission to free Valin and Jysella Horn, who were captured by the Galactic Federation of Free Alliances, encased in carbonite, and placed in the Detention Center because they fell prey to a Force psychosis. Shortly after their rescue the Horn children fled, because they were still under the influence of a twisted, immortal entity known as Abeloth. Jaina then helped the Jedi under the leadership of acting Grand Master Saba Sebatyne to remove Daala from power before she could strike at the Jedi. After the successful coup she went on the hunt for Abeloth with her uncle Luke, Ben and Vestara Khai. After an unsuccessful search on Korriban and an encounter on Dromund Kaas they returned to Coruscant to recuperate.
During Jaina's next mission on the planet Upekzar, Abeloth who had recently possessed Senator Rokari Kem arranged her own installment as Chief of State and took control of Coruscant and the Galactic Alliance. In the following fight for Coruscant Jaina stopped a Sith called Tela Rovas and participated in the fight for the Jedi Temple. During the latter Luke Skywalker promoted her to the rank of a Jedi Master and Ben was captured by Abeloth. Luke and Jaina followed Abeloth to her home-world where she was finally defeated.
Shortly afterwards Jaina finally married Fel and they spent their honeymoon on the remote world of Sakuub, where they came into conflict with their local guide Pharika over a recently found Jedi holocron.
