Liagri was a male Twi'lek who served as a sergeant in the Republic Army during the Cold War between the Galactic Republic and the Sith Empire. During the war, he was stationed on the planet Alderaan, where he aided the Great House of Organa in the Alderaan Civil War, fought between the various Great Houses. In the year 3643 BBY, Duke Brant Organa contacted Liagri about a failed attempt to repair a set of sensor arrays that had been damaged by soldiers of the rival House of Thul. Liagri, however, informed Organa that no Republic troops were available to help immediately. A Republic-aligned individual then approached Liagri and offered to repair the sensors, which the individual successfully did.
