The Rebel hangar served as a former sanctuary for the Rebel Alliance. It was situated on the Outer Rim world of Dathomir. This hideout's construction predates 1 ABY by several years. Imarrra, a Wookiee, had previously visited Dathomir and possessed knowledge of this particular site.
In 1.5 ABY, Imarrra, alongside fellow Wookiee Orrekazzapirr, were seized on Kashyyyk and subsequently transported to the Imperial prison located on Dathomir. A spacer, dispatched by Queen Kylantha of Naboo, successfully infiltrated the prison and facilitated their liberation. Imarrra recalled the hangar's existence, and together with Orrekazzapirr, they navigated the Dathomirian terrain to reach it. Inside, they discovered a vintage ARC-170 starfighter, which they utilized to breach the Imperial blockade and flee the planet.
The Rebel hangar was featured in the Star Wars Galaxies video game. This massively multiplayer online roleplaying game was created by Sony Online Entertainment and distributed by LucasArts, before its shutdown on December 15, 2011.
