For the non-fan
Commander Benjamin Sisko (Avery Brooks) is the Starfleet officer placed in charge of Deep Space Nine. At the start of the series, he is a grieving widower (his wife having been killed by the Borg at the Battle of Wolf 359) and the father of a teenage son, Jake. He and Jadzia Dax discover the Bajoran wormhole, which the Bajorans believe is the home of the Prophets, their gods and protectors. The Bajorans hail Sisko as the Emissary of the Prophets, an exalted religious status that initially makes him very uncomfortable.
Major Kira Nerys (Nana Visitor) is a Bajoran militia officer, former guerrilla fighter during the Cardassian Occupation of Bajor, and, as the station's Bajoran liaison officer, Sisko's second in command. She is initially suspicious of the Federation's intentions toward her planet, but grows to trust and befriend the rest of the crew. Like most Bajorans, she is deeply religious, which makes it awkward having the Emissary as her commander.
Winn Adami (Louise Fletcher) is an ambitious Bajoran religious leader and the first kai elected after the Cardassian Occupation. A member of a frequently outspoken orthodox order, Winn often came into conflict with the Emissary of the Prophets, Starfleet Captain Benjamin Sisko.
Constable Odo (Renee Auberjonois) is the station's incorruptible chief of security. He is a Changeling, capable of assuming any shape he wishes. He was found in the Denorius Belt, brought back to the planet Bajor by the Cardassians (who maintained a military occupation of Bajor), and raised in a laboratory by a Bajoran scientist, Doctor Mora. Odo yearns to find his own people, and is very protective of Major Kira.
Dr. Julian Bashir (Alexander Siddig) is the station's very self-confident, yet brilliant chief medical officer. Somewhat tactless, he has feeling for Dax.
Quark (Armin Shimerman) is the owner of a bar. Like most of his species, he is extremely greedy and willing to do whatever it takes to acquire more latinum. This almost invariably brings him into conflict with Odo. Quark does however display a moral code on several occasions during the series, electing to save lives rather than obtaining monetary benefit.
Chief Miles O'Brien (Colm Meaney) is the Chief of Operations, keeping the station in working order. He is married to botanist and teacher Keiko whom he met while serving as Transporter Chief on the U.S.S. Enterprise. They have a daughter, Molly..
Lt. Jadzia Dax, (Terry Farrell)a Trill, is the station's science officer. She shares her life and thoughts with a long-lived symbiont named Dax, which has already experienced seven prior lives "joined" with other Trills. The previous host, larger-than-life rogue Curzon Dax, had been a close friend of and mentor to Sisko.
Keiko O'Brien (Rosalind Chao) is married to Chief O'Brien and is the mother of Molly. She served as a civilian botanist aboard the U.S.S. Enterprise, but is now the primary school teacher aboard DS9.
Molly O'Brien (Hanah Hatae) is the daughter of Miles and Keiko O'Brien. She is four years old.
Nog (Aron Eisenberg) is Quark's nephew and good friend to Jake Sisko.
DEEP SPACE NINE - One of the most historically, politically, and strategically important space stations in the Alpha Quadrant, Deep Space 9, originally known as Terok Nor, was an orbital space station constructed by the Cardassians in orbit of Bajor. Under Federation administration following the Cardassian withdrawal, DS9 became a vital commercial port and defensive outpost because of its strategic location near the mouth of the Bajoran wormhole.
THE BAJORAN WORMHOLE - is the only stable wormhole currently known to exist in the galaxy. The terminus nearest to the Federation is located in the Denorios belt in the Bajoran system, and crosses some 70,000 light years to a point near the Idran system in the Gamma Quadrant. The wormhole is also the home of extra-dimensional beings who are worshiped by the Bajorans as the Prophets, and therefore is also sometimes referred to as the Celestial Temple.
