The Nouane system, which held the planet Nouane, existed within the Nouane sector - an autonomous region situated in the Inner Rim of the galaxy. This star system became a client-state under the Galactic Empire during the fifth year of Emperor Palpatine's reign.
James Luceno's 2014 novel, Tarkin, marked the canonically initial appearance of the Nouane system. Conversely, within the Star Wars Legends timeline, the system was initially referenced within The Essential Atlas, a 2009 reference book authored by Jason Fry alongside Daniel Wallace.
