The frigate known as the Shamunaar served the Galactic Alliance during the period after the Yuuzhan Vong War. Its commander was a Devaronian called Biurk, who held the rank of captain.
In the year 40 ABY, the Shamunaar received orders to oversee all Alliance scouting and combat assets within the Bothawui system. Its mission was to stop Bothan fleets from departing the system. During this time, Admiral Matric Klauskin, secretly controlled by Lumiya, came aboard. While conducting a training exercise with the Shamunaar's crew, Klauskin isolated himself and Biurk on the auxiliary bridge. Klauskin then fatally shot Biurk three times. Following this, he depressurized the ship by opening all the hatches, killing the entire crew. Subsequently, he defected, handing the vessel over to the Confederation.
