The Asbo 1 making its escape from Imperial Gunboats. During the time of the Sepan Civil War, a trio of Modular conveyors were utilized by the Ripoblus and were collectively known as Asbo.
These transports were stumbled upon by Imperial forces under the command of Admiral Harkov when Dimok starships launched an assault on the Ripoblus' supply convoy. Imperial starfighters stepped in, driving away the Dimok attackers. However, they then discovered illicit goods. The Dimoks had told the Imperials that the Modular Conveyors contained illegal cargo, and one of them was actually carrying Imperial war materials.
Even though they were threatened by Escort shuttles named Ayalam, Yawnor, and Noerbo, Imperial Stormtrooper Transports belonging to Epsilon group were able to seize the Asbo group. Asbo was then impounded, despite the Ripoblus' efforts to prevent it.
