In the procedure as a Jedi Knight, Jacen assisted defending the New Republic and New Jedi Order from multitudinous plots, and terrorist assaults.
In 24 ABY Jacen and his younger brother, Anakin Solo, were declared apprentices of their uncle Luke Skywalker; also notorious for the title and ranking of Jedi Grand Master of the New Order of Jedi.
Jacen has always been a curious, yet uncertain child. A philosopher who difficultly endeavoured to comprehend the Force, as well the Galaxy. He also struggled to perceive with the conception of apply violence to conflict violence solves any matter.
Jacen experienced a particular crisis when the Yuuzhan Vong war transpired.

"The Yuuzhan Vong aren't all warriors. They are women and children, too. They are slaves, and outcasts, and scientists, and workers. They have as much right to life as we do. There is no question about that."
Shortly after the Yuuzhan Vong war was over. Jacen perceived, and concluded that more wars similar to the Vong war would occur in the future. And that he had to be prepared for them in order to halt them. Jacen then vanished-severing all ties of connection with everyone he had ever knew, and voyaged into the Unknown Regions to discover various Force-utilizing techniques which severed as a powerful advantage for him in the future.
