Death Star
Although details, such as the superlaser's location, shifted between different concept models during production of "Star Wars", the notion of the Death Star being a large, spherical space station over 100 kilometers in diameter was consistent in all of them. George Lucas gave the original task of designing a "Death Star" to concept artist and spaceship modeler Colin Cantwell, who had collaborated with Stanley Kubrick on the 1968 film "". In a 2016 interview, Cantwell related that "I didn't originally plan for the Death Star to have a trench, but when I was working with the mold, I noticed the two halves had shrunk at the point where they met across the middle." As it "would have taken a week of work just to fill and sand and refill this depression," Cantwell suggested a trench to Lucas to save the labor. Lucas liked the idea, and the Death Star model was created by John Stears. The buzzing sound counting down to the Death Star firing its superlaser comes from the "Flash Gordon" serials. Portraying an incomplete yet powerful space station posed a problem for Industrial Light & Magic's modelmakers for "Return of the Jedi". Only the front side of the 137-centimeter model was completed, and the image was flipped horizontally for the final film. Both Death Stars were depicted by a combination of complete and sectional models and matte paintings.
Star Wars: Jedi Knight
In the first level of "Dark Forces", which is set prior to "A New Hope", Katarn recovers the plans to the Death Star, a heavily armed space station capable of destroying entire planets. The Rebel Alliance uses the plans to find a weakness in and then destroy the Death Star. Katarn then aids the Rebels in stopping the threat of the Imperial "Dark Trooper" project. Despite the successful missions on behalf of the Alliance, however, Katarn does not join their cause. "Dark Forces II" begins several years after the destruction of the second Death Star in "Return of the Jedi", when Katarn is informed of the exact details of his father's death. His father, Morgan Katarn, had discovered the location of "The Valley of the Jedi", a source of great Force power, but a Dark Jedi named Jerec murdered Morgan in an attempt to find the location. Katarn travels to the Valley of the Jedi while learning the ways of the Jedi himself. Eventually, he confronts and defeats Jerec, avenging his father's death. However, Katarn still does not join the Jedi Order, instead using his powers for the New Republic, and taking on an apprentice with a similar history to himself; Mara Jade. During this time, Katarn learns of a Sith temple on the planet Dromund Kaas. There, Katarn is corrupted by the Dark Side of the Force. However, Jade is able to convince him to return to the Light and they leave together.
