The Imperator, an Immobilizer 418 cruiser, served within the Imperial Navy throughout the Galactic Civil War. Stationed with Black Sword Command at a shipyard within the Koornacht Cluster, its fate took a turn when the indigenous Yevetha overwhelmed it. The Yevetha seized all of the Command's assets, renaming the vessel Splendor of Yevetha. This ship was then deployed against the forces of the New Republic.
Following the Battle of Endor, the Yevetha aliens captured this vessel from the Imperial forces of Black Sword Command. Subsequently, the ship joined the fleet of the Yevethan Duskhan League and, in 16 ABY, was instrumental in the capture of the New Republic fleet shuttle Tampion, along with the abduction of General Han Solo.
As the Splendor of Yevetha, the former Imperator participated in the New Republic's confrontation with Nil Spaar's forces at N'zoth. During the Battle of N'zoth in 17 ABY, surviving Black Sword personnel, led by Major Sil Sorannan, reclaimed her and the other Imperial-designed vessels in Duskhan League service. They then redirected the ship towards Byss in the Deep Core.
