A supply base, belonging to the Galactic Empire, existed on the planet of Imdaar throughout the Imperial Era. Following the Rebel Alliance's destruction of the Empire's superweapon, the Death Star, the Alliance bombed the Imdaar facility in 0 ABY.
Princess Leia Organa expressed her opinion that the Alliance's fight against the Empire was insufficient during a gathering of Rebel Alliance leaders later in that year. Admiral Gial Ackbar responded to this statement by referencing the bombing of the base, citing it as an instance of the Alliance's activities after the Death Star's obliteration.
The Star Wars comic series from 2015 included a reference to the supply base in its fourth issue. Marvel Comics released the issue, penned by Jason Aaron, on April 22, 2015.
