Star Trek: Deep Space Nine

Star Trek: Deep Space Nine (DS9) focuses on the 24th century adventures of Captain Benjamin Sisko on space station Deep Space 9, an outpost situated near the mouth of a stable wormhole on the far reaches of explored space. Although Sisko commands Deep Space 9, the station actually belongs to the inhabitants of nearby Bajor, who requested Starfleet's protective presence after Bajoran freedom fighters put an end to the brutal Cardassian occupation of their world. Approximately a sixth of the station's 300 permanent residents are Starfleet personnel; there is also a sizable Bajoran militia presence. The rest of Deep Space 9's inhabitants are civilians, most of whom work in the station's Promenade, a kind of indoor marketplace. Initially, Sisko's mandate from Starfleet was to protect Bajor and the station from any hostiles who ventured into the area. But with the discovery of the nearby wormholea shortcut through space that leads directly to the uncharted Gamma quadrantSisko's mandate has expanded exponentially, as the region becomes the gateway to all manner of visitors, both friendly and extremely hostile.
