Threna
this misplaced Supreme-class servant droid was sent to the planet Grathus upon being manufactured. The natives of Grathus had been expecting a load of waste treatment parts, but the shipping company delivered the droid by mistake. Xig Rollem purchased the droid and altered its programming, giving it the name Threna and employing the droid as a bartender at his cantina. The droid'd original programming was basically unaltered, though, and it acted with the utmosy courtesy to Rollem's patrons, most of whom were rowdy miners and hired hands. However, over time, Threna's demeanor actually rubbed off on the patrons, who gradually became more refined.
