Atril Neff

Atril Neff was a Human female hailing from the planet Ertegas. She had a brother named Allen, who moved to the planet Bespin and eventually followed her into service in the Bespin Wing Guard. In the Wing Guard, Neff eventually became an immigration officer with the rank of Lieutenant. Her job was to know who entered and left Bespin's Cloud City. She was good at her job, and knew who entered and left the city. When Imperial forces led by the Sith Lord Darth Vader occupied Bespin in 3 ABY, Neff's curiosity was piqued by Vader's presence. Due to her curiosity, she tried to catch a glimpse of the Dark Lord of the Sith whenever possible. Neff had dark hair and light skin. She was armed with a Relby-k23 blaster pistol.
