Alderaan (ˈɔːldərɑːn,_-ræn) is a fictional planet featured in the Star Wars franchise. It is blue-green in appearance, depicted as a terrestrial planet with humanoid inhabitants, and characterized by a peaceful culture. It is the home planet of Princess Leia Organa, one of the lead characters in the film series, as well as former Rebel shock trooper Cara Dune. In the original 1977 film, Alderaan is destroyed by the Death Star's superlaser. Early drafts of the Star Wars story include references to at least two planets which later evolved into the concept of Alderaan. Star Wars author George Lucas included a planet called Alderaan in early treatments; in The Star Wars (1973), Alderaan is a city-planet and the capital planet of the galaxy (prefiguring the planet Coruscant which later featured in the films). The draft script opens with a scene in which an "eerie blue-green" planet called Aquilae is threatened by an armed space fortress. In Lucas' 1975 draft, Adventures of the Starkiller as taken from the Journal of the Whills, Saga I: The Star Wars, the capital planet of Alderaan is described as a floating city in the clouds, "suspended in a sea of cirrus methane". A planet described in Lucas' draft script as being "under siege by the Imperial Legions of Alderaan" and which is later destroyed is named as Ogana Major. Early sketches commissioned by Lucas from conceptual illustrator Ralph McQuarrie show a design which very closely resembles Cloud City, as featured in the later sequel, The Empire Strikes Back. In Lucas' third draft, the Imperial City of Alderaan has become the home world of the Sith Lords, and Darth Vader holds Princess Leia captive here. Lucas continued to hone his script, aided by screenwriters Willard Huyck and Gloria Katz; names of planets and characters were revised and the narrative was improved, and by the fourth draft, scenes on the Imperial capital planet had been moved to a space station called the Death Star and the peaceful world destroyed by the Empire had taken the name Alderaan.
