Jadzia Dax is a joined Trill. Though she appears to be a young woman, Jadzia lives in symbiosis with a wise and long-lived creature, known as a symbiont, named Dax. The two share a single, conscious mind, and her personality is a blending of the characteristics of both the host and the symbiont. As such, Jadzia has access to all the skills and memories of the symbiont’s seven previous hosts. Jadzia holds academic degrees in exobiology, zoology, astrophysics and exoarchaeology, all of which she earned before the joining.
