Star Trek: Deep Space Nine is about a space station called deep space nine. Formerly called, Terok Nor, the space station was constructed by the Cardassians in orbit of Bajor during their occupation of the planet. The station came under Federation administration after they freed Bajor. In the first episode the station is move slightly away from Bajor because of the discovery of a wormhole to the Gamma Quadrant. The first couple seasons are boring, seeing not much happens on a space station. But things get more interesting when a force called the, Dominion, from the Gamma Quadrant try to take over the Alpha Quadrant and Deep Space Nine is on the front lines!
