Captured from Imperial forces of the Black Sword Command after the Battle of Endor by the alien Yevetha, this ship subsequently entered the fleet of the Yevethan Duskhan League, and was used in 16 ABY to capture the New Republic fleet shuttle Tampion, and to kidnap General Han Solo.
Renamed Splendor of Yevetha, the Imperator was present at the New Republic's showdown with Nil Spaar's forces at N'zoth. With the rest of the Imperial-designed ships in Duskhan League service, she was recaptured by surviving Black Sword personnel under the leadership of Major Sil Sorannan during the Battle of N'zoth in 17 ABY, and redirected to Byss in the Deep Core.
The Imperator/Splendor of Yevetha was described as an Interdictor Dreadnaught in Shield of Lies. It was later clearly identified as an Immobilizer 418 in its entry in The Complete Star Wars Encyclopedia.
