Jacen Solo, the son of princess Leia Organa of Alderaan and General Han Solo, was a legendary force-sensitive human male Jedi Knight during the New Republic Era. He grew up during the days of the New Republic, an era of mostly peace, knowing happiness and stability, with the love and support of his mother.
Possessing prodigious abilities as a Force wielder, Organa was taken on as a Jedi student by his uncle Luke Skywalker at the age of ten years old, and he traveled the galaxy with the Jedi Master acquiring lost knowledge of the Jedi religion. Proving a powerful apprentice, Solo mastered his training swiftly, and soon came to be Master Skywalker's most gifted pupil, surpassing other students put together, and showing worthiness of his grandfather's lightsaber.
After the destruction of his uncle's temple at the hands of his brother, who renamed himself Kylo Ren, Organa renounced his lineage as Skywalker and Jedi Knight, discarding his lightsaber and closing himself off from the Force. Solo worked as a smuggler and mercenary to sustain himself for three years, drinking and gambling addictively, before he received a vision through the force of his father's death at the hands of his half brother.
Birth of a Prince
Jason Solo was born in 5 ABY within Hanna City, Chandrila on the day that the Galactic Concordance was signed between the New Republic and the Galactic Empire, formally ending the Galactic Civil War, one year and four days after the Battle of Endor, in which his mother, Princess Leia Organa, along with her companions, led the Alliance to Restore the Republic in a decisive victory over the Empire. While he was still in his mother's womb, Leia could feel him through the Force. She likened him to a living band of light that demonstrated he was nothing but an innocent soul untouched by the poison of darkness and anguish.
Leia Organa's lightsaber
In 35 ABY, upon the death of his mother, and his uncle already passing away the year prior, Jacen inherited his mother's lightsaber and began to wield in unison with his uncle and grandfather's. Just as his mother predicted thirty years earlier, Jacen picked up her lightsaber and finished her Jedi path for her, while also fulfilling what his uncle never did, passing it on to a promising student. Upon holding the saber for the first time, he vowed to keep it as a memento for the loss of his mother, and to make up for never reconciling with her before her passing.
Solo used the lightsaber during his final battle.
