Death Star
The Death Star is a type of fictional mobile space station and galactic superweapon featured in the "Star Wars" space opera franchise. The first Death Star is stated to be more than 100 km to 160 km in diameter, depending on source. It is crewed by an estimated 1.7 million military personnel and 400,000 droids. The second Death Star is significantly larger, between 160 km to 900 km in diameter depending on source, and technologically more powerful than its predecessor. Both versions of these moon-sized fortresses are designed for massive power-projection capabilities, capable of destroying multiple naval fleets or entire planets with one blast from their superlasers.
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.
