The Human female Atril Neff served as an immigration officer with the rank of lieutenant in the planet Bespin's Wing Guard during the Galactic Civil War between the Galactic Empire and the Alliance to Restore the Republic. She had a brother named Allen, who hailed from the planet Ertegas and moved to Bespin at age six, eventually following his sister into service in the Wing Guard. Neff's job in the Wing Guard was to know everyone who entered and left Bespin's Cloud City. She was present on Cloud City when Imperial forces led by the Sith Lord Darth Vader occupied Bespin in 3 ABY.
During Lieutenant Neff's service in the Bespin Wing Guard, she wore the standard uniform and was armed with a Relby-k23 blaster pistol.
