As a Saheelindeeli woman, Fadoop operated as a local trader on her native planet of Saheelindeel, found within the Tion Hegemony, during the Galactic Civil War period. Fadoop, a female, conducted her affairs from a makeshift ship named Skybarge, and was remarkably heavy and sociable for one of her species, often dealing with visitors from other worlds. In 2 BBY, Fadoop crossed paths with Han Solo, a Corellian smuggler, who was then employed as a mechanic for Grigmin's Traveling Airshow. Fadoop established a cordial bond with Solo and his first mate Chewbacca, exchanging parts with them between her cargo runs. Fadoop even permitted Solo to use her ship after he chose to leave his position with the boastful pilot Grigmin, with Solo employing Skybarge to outfly and embarrass Grigmin.
The sole appearance of Fadoop in the Star Wars Legends storyline was in the Brian Daley penned novel, Han Solo and the Lost Legacy, which was published in 1980.
