Editing Jacen Solo (section)

===Jedi Academy years===

In the ''[[Young Jedi Knights]]'' series, Jacen travels to [[Yavin 4]] with his sister to begin his Jedi training. Jacen discovers a strong connection to the Living Force &mdash; the concentration on the present moment &mdash; and can communicate with and calm many of the jungle creatures near the Academy. He even keeps a small menagerie of animals in his room in the Great [[List of Star Wars races (K-O)#Massassi|Massassi]] Temple. He and his sister befriend the [[Wookiee]] [[List of New Order Jedi characters#L|Lowbacca]] (nicknamed Lowie by his friends) and the warrior princess [[List of New Order Jedi characters#K|Tenel Ka]].

In ''[[Heirs of the Force]]'' and ''[[Shadow Academy]]'', Jacen and Jaina discover a crashed [[TIE fighter]] from the Battle of Yavin. Jaina installs a hyperdrive in the downed starfighter and begins fixing it to fly again. Jacen, Lowbacca, and Tenel Ka help her to practice their Force skills until all are held captive by the TIE's original pilot, Qorl, who had been living in the jungle for two decades. They eventually escape, but so does Qorl, leaving the jungle moon behind and searching for any remnants of the [[Galactic Empire (Star Wars)|Galactic Empire]]. Qorl discovers the Shadow Academy, a training ground for Dark Jedi commanded by one of Luke Skywalker's fallen students, [[List of Star Wars Legends characters#Brakiss|Brakiss]], along with the remains of the [[Dathomir]]i [[Nightsisters]]. These elements of the so-called Second Imperium kidnap Jacen, Jaina and Lowbacca, but they resist the dark side and are rescued by Luke Skywalker and Tenel Ka.

The friends return to Coruscant for a short vacation, and are reunited with the twins' childhood friend [[Zekk (Star Wars)|Zekk]]. They are forced to fight Jacen and Jaina several times, and the twins and their friends finally progress far enough to be tasked with building their first lightsabers. Jacen uses a corusca gem he had gained earlier for his focusing crystal.

Jacen's hard-learned lesson hits home once again in ''[[Lightsabers (novel)|Lightsabers]]'', when Tenel Ka rushes to complete her lightsaber to keep up with her friends. She uses an imperfect crystal and her blade shorts out in a sparring match with Jacen. His lightsaber passes through thin air where her weapon had been seconds before and severs the young woman's arm. Though she bears him no ill will for the accident, Jacen is wracked with guilt.

In ''[[Darkest Knight]]'', the twins and Tenel Ka go to [[Kashyyyk]] with Lowbacca to witness his sister's adulthood rites. In ''[[Jedi Under Siege]]'', the Jedi trainees and the Shadow Academy have their final confrontation on [[Yavin 4]]. The twins, with help from Luke and Zekk, bring down the Shadow Academy and the Second Imperium forever.

Throughout the series, Jacen and Jaina continue their training at [[Yavin 4]], meeting new friends like [[Raynar Thul]]. They cannot convince Zekk to stay at the Academy with them, but Jacen and Jaina remain friends with him. With his and Raynar's help, they discover a threat to the New Republic: the Diversity Alliance, an alien, anti-human group. The Alliance is building up massive support among peoples that had been oppressed by the Empire. They are led by a [[Twi'lek]] Nolaa Tarkona, the sister of [[Minor residents of Tatooine#Oola|Oola]], who was murdered by [[Jabba the Hutt]] in ''[[Return of the Jedi]]''.

In ''[[Jedi Bounty]]'', Jacen, Jaina, and their friends are briefly held captive on [[Ryloth]] and have to escape to its harsh surface. They have gone there in an attempt to rescue Lowbacca, who had misguidedly joined the anti-human Diversity Alliance. In the following book, ''[[The Emperor's Plague]]'', they get to the bottom of a plot they had suspected all along, and catch up with Raynar's father, Bornan Thul, to race the Diversity Alliance fleet to an Imperial storehouse hidden in the deep core. There is hidden a supply of deadly diseases created by [[List of minor Star Wars villains#Derricote, General Evir|General Evir Derricote]] almost two decades before. Tarkona wishes to unleash a [[Plague (disease)|plague]] against humans and wipe them all out, but the Jedi and Alliance dissidents defeat her. She succumbs to one of the diseases herself on a faraway planet. Bornan Thul dies from one of the plagues right before his son's eyes.

In ''[[Return to Ord Mantell]]'', they go on a trip with their father to the titular planet to watch a race. There, they run into Czethros, a bounty hunter who once hunted Han. They are ambushed by [[w:C:starwars:Black Sun|Black Sun]] agents, but are helped by Anja Gallandro, a young woman who wields a lightsaber, though she is not a Jedi. Although attracted to Tenel Ka, Jacen becomes infatuated with the older woman. Anja had blamed Han Solo for killing her father, but Solo reveals that her father died in a trap while finding treasure.

In ''[[Trouble on Cloud City]]'', they discover Czethros is a minor leader of Black Sun, and is trying to gather enough power to overcome the [[New Republic (Star Wars)|New Republic]]. Jacen, Tenel Ka, and Lowbacca are ambushed by several Black Sun [[mercenary|mercenaries]], and Jacen is almost killed.

In ''[[Crisis at Crystal Reef]]'', Jaina attempts to help [[Kessel (Star Wars)|Kessel]] and capture Czetheros while Jacen rushes to help Anja with her spice addiction and help her with Black Sun. With help, Anja beats her addiction and accepts her father's death. Jacen thinks Anja has Jedi potential, but it turns out she didn't. He gets over his infatuation with Anja when she goes to work for Lando.
