As a child, she was kept at the Jedi base Shelter located in the Maw for protection during the Yuuzhan Vong war. Saav'etu became good friends with Jysella Horn. The Bothan proved to be loyal and helpful to Horn, who was making her way through a hard time because her brother, Valin Horn, had been recently diagnosed with a Force-related illness that caused him to think everyone around him were impostors. As a result he was incased was incased carbonite. Yaqeel was part of a close-knit group of friends consisting of Bazel Warv, Valin Horn, and Jysella Horn.
While at a tapcaf across from the Jedi Temple, Saav'etu and Warv witnessed Jysella Horn tossing civilians across the Processional Way. Rushing out to stop her, the two Jedi were attacked by Horn, who used flow-walking to predict their movements. After slashing Warv in the chest, Horn escaped, only to be captured by Galactic Alliance Security forces shortly after. Master Cilghal and several other Jedi rushed onto the scene, escorting Saav'etu and helping Warv to the Temple for healing and debriefing.
Saav'etu and Warv were wandering back to the Temple by way of Fellowship Plaza when the Bothan developed the psychosis. Warv, attempting to calm her and lead her into the Temple via the southern speeder entrance, was assisted by Han, Leia, and Jaina Solo, along with Imperial Remnant Head of State Jagged Fel. They tranquilized her, but Barv also contracted the psychosis and had to be stunned as well. The two Jedi were then hidden in the Temple as a Security force under the command of Captain Atar arrived with a warrant to arrest them. They managed to evade being forced to hand over Warv and Saav'etu.
Later, a mission to evacuate Saav'etu and the other psychotic Knights from the Jedi Temple was undertaken by Han, Leia, Jedi Knight Jaden Korr, and Jedi Knight Avinoam Arelis. They were attacked by Mandalorian Supercommandos, but with the help of Warv managed to fight them off. Saav'etu, Warv, and the other psychotic Knights were then loaded into a FloatVan that took them safety. Soon after, Saav'etu, Warv, Wan, and Hellin were smuggled offworld by the Solos and taken to Shedu Maad in the Hapes Cluster to escape the Galactic Alliance.
In 44 ABY, Yaqeel and the other Jedi suffering from the mysterious Force psychosis snapped out of their delusions in the aftermath of Luke Skywalker's first battle with Abeloth on Abeloth's planet. They were brought from Shedu Maad to the Jedi Temple by Zekk and Tekli. Yaqeel participated in the rescue attempt of Jysella and Valin Horn as the leader of "Team Saav'etu." Disguised as exterminators, the team used foam coating to mask the cam bubbles of the facility and then breached the outer walls with thermal detonators. Inside, the team discovered thousands of prisoners frozen in carbonite alongside the Horn siblings. Despite fierce opposition from Galactic Alliance Security forces, the Horns were successfully rescued.
