A heavyset, barrel-chested Sullustan, Mister Borkus is the proprietor of a no-frills diner in Pons Ora, a small settlement on the mostly unknown world of Abafar. The opportunistic Borkus stumbled upon a clone commando suffering from amnesia. The soldier had escaped a devastating battle, and was stripped of his memory and his identity. Borkus callously took the clone -- Gregor -- under his care, never revealing his origin to the grateful survivor. Borkus "generously" offered to give Gregor room and board, at an expense, and also employed him as a dishwasher. But Gregor's meager wage wasn't enough to pay for his necessities, and thus the lowly dishwasher was little more than Borkus's slave.
Nien Nunb is a small, jowled, mouse-eyed native of Sullust, the world that served as the staging area for the Alliance Fleet prior to the Battle of Endor. Nunb was co-pilot to Lando Calrissian aboard the Millennium Falcon during that historic event. Many of his fellow Sullustans also served as Alliance starfighter pilots in the battle. Nunb spoke the liquid, chattering tongue of the Sullustans, a language Lando understood.
