Refnar, a planet, resided within the Refnar system, which was situated in the Pakuuni sector of the Slice region, itself a part of the Outer Rim Territories. During the initial stages of the Galactic Civil War, it served as the location for a Rebel Alliance base. By approximately 1 BBY, the Galactic Empire had located this base and initiated an attack. In the resulting battle between the Alliance and Imperial forces, an event remembered as the "Last Stand at Refnar," the majority of the Rebel freighters, troop transports, and starfighters successfully fled the Refnar system.
Ed Stark conceived Refnar, and it debuted in Cracken's Rebel Operatives, a 1994 sourcebook from West End Games designed for use with Star Wars: The Roleplaying Game. The 2009 reference work, The Essential Atlas, designated the Refnar system, and consequently the planet Refnar, as being in grid T-6.
