The Supreme-Class Servant Droid, a sophisticated droid made by Lovolan, was designed to serve the elite on worlds such as Coruscant and Cloud City. Possessing fluency in numerous languages and dialects, along with comprehensive insights into the pastimes and concerns of the upper crust, the Supreme-Class also features a communications network that provides access to financial and news information. A specific Servant-Class unit, known as Threna, was accidentally left behind on the planet Grathus, where it eventually found employment as a bartender at Xig Rollem's establishment.
