Jadzia Dax

Jadzia Idaris was born in the year 2341 on the planet Trill. She had one younger sister, Ziranne. Her mother's name was Kela Idaris. (DS9 short story: "Reflections", novel: Trill: Unjoined)

Jadzia knew from a very young age that she wanted to be joined, and worked all of her life towards that goal. To prove her value, she earned distinctions in exobiology, zoology, astrophysics, and exoarchaeology. (DS9 episode: "Dax", game: Star Trek: Starship Creator) She was eventually joined with the Dax symbiont in early 2367, after the death of the previous host, Curzon.

Later that year, she participated in an archeological dig on the planet Pandora, where she encountered a powerful object called the Codex. (DS9 short story: "Chiaroscuro")

Dax graduated Starfleet Academy in 2368 in the 98th percentile. (Star Trek: Starship Creator)

In 2369, Lieutenant Jadzia Dax was transfered to Starbase Deep Space Nine, as science officer. (DS9 episode and novelization: "Emissary")

In the summer of 2371, Jadzia helped her friend and fellow Trill Moll Enor when Moll was on trial for endangering her symbiont. In 2372, Jadzia returned to Trill when her sister Ziranne mysteriously turned up in a hospital joined to the Roa symbiont. This led Jadzia to a symbiont black market being run by Verad Kalon, an unjoined Trill who had stolen the Dax symbiont from Jadzia briefly in 2370. With the assistance of the Trill Symbiosis Commission, Jadzia found Verad and ended his operation. (DS9 short story: "Reflections")

At the end of 2372, Jadzia Dax was promoted to Lieutenant Commander. (DS9 episode and novelization: "The Way of the Warrior")

In 2374, she was married to Worf, Son of Mogh, and inducted into the House of Martok. (DS9 episode "You Are Cordially Invited...")

Later that year, Dax was attached to Project Blue Sky, a scientifically orientated war research project conducted in conjunction with the Romulans. Jadzia and Romulan Subcommander T'Rul attempted to create an enzyme that was supposed to alter the genetic profile of the Jem'Hadar, without success. (DS9 short story: "The Devil You Know")

Jadzia was murdered in late 2374 by Skrain Dukat. The Dax symbiont survived and was eventually rejoined with Ezri Tigan. Jadzia Idaris' body was returned to Trill and buried there. (DS9 novel: Trill: Unjoined)
