A Kilji known as "Vassal Two" served the Kilji species' government, the Kilji Illumine, as a Kilji vassal, a follower of the Illumine's beliefs. In 18 BBY, they served aboard the Kilji war cruiser Anvils sensor station under General Crofyp, an officer of the Illumine. After Crofyp's task force, consisting of the Anvil and the Kilji picket cruiser Hammer, traveled to the Unknown Regions' Rapacc system in order to retrieve a group of refugees, it was confronted and prevented from doing so by the Paccosh-commandeered Nikardun blockade frigate Aelos. Following the confrontation, Vassal Two informed Crofyp that the Chiss heavy cruiser Springhawk had appeared to the Anvils starboard, and the Chiss starship subsequently destroyed Crofyp's cruiser.
