Curzon Dax led a very long and full life, having lived past his 100th birthday (Rejoined). He was a womanizer, and loved to play Tongo. He was a top Ambassador of the Federation in the late 2280s and the 2290s. In 2289, he represented the Federation during negotiations at the Korvat colony (early negotiations between the Klingons and the Federation), and in 2293, he represented the Federation at the Khitomer Conference.
The Klingon representatives at the Korvat negotiations were Kang, Kor, and Koloth. Curzon walked out of the conference while Kang was speaking, but this opened the door for Curzon to form a close relationship with all three Klingon warriors. Curzon and Kang became such good friends, that when Kang's first child was born, Curzon was his godfather. When the Albino killed the sons of all three Klingons, Curzon entered into a blood oath with them to avenge the deaths. (DS9: "Blood Oath")
Around 2339, Curzon was involved in resolving the Klaestron Civil War. He became a friend of the Klaestron General Ardelon Tandro and had an affair with Ardelon's wife Enina Tandro. In 2369, Curzon Dax was accused post-mortem of treason and murder for killing Ardelon Tandro. The Dax symbiont was placed on trial for the crimes. When Ardelon's widow came forward to admit the truth, Curzon was cleared, and Jadzia Dax was set free. (DS9: "Dax")
Curzon was a friend and mentor to Benjamin Sisko for nearly twenty years. Sisko affectionately dubbed him "old man" and continued to use the name for both Jadzia and later Ezri. Curzon met Sisko at Pelios Station when Sisko was an ensign, the two later served on the USS Livingston together. (DS9: "Emissary", "Invasive Procedures")
In 2369 Sisko told Julian Bashir about Curzon's perverse pleasure giving Sisko assignments like the service for VIP guests. Sisko "graduated" from these assignments after he hit one of the guests. (DS9: "The Forsaken")
Curzon was also known and feared for "breaking" Trill initiates as a field docent for the Symbiosis Commission, and even eliminated Jadzia from the program. She later re-applied and succeeded in being approved for joining. She asked to be next in line for the Dax symbiont, and Curzon gave his consent. He later revealed to Jadzia during her zhian'tara that he had actually been in love with her, and that this, not any fault of hers, was the reason he originally eliminated her from the program, unable to actually be with her as his role as her supervisor made such a relationship inappropriate, accepting her re-application partly out of guilt that he'd nearly cheated her of something she'd wanted all her life. (DS9: "Playing God", "Facets")
Curzon once told Benjamin Sisko that the only persons who can handle Klingons are Klingons. In 2372 Sisko remembered this, and subsequently invited Worf aboard the station to investigate General Martok's task force. (DS9: "The Way of the Warrior")
Curzon died of strain incurred while seeking jamaharon on Risa with Arandis in 2367. His final days were spent in a hospital room yelling at the doctors and friends who were trying to keep him alive. He finally died as his family assembled at his bedside, as the symbiont was removed and implanted in a new host, becoming Jadzia Dax. (DS9: "Let He Who Is Without Sin...", "Blood Oath")
During Jadzia's zhian'tara, Odo claimed the personality and memories of Curzon. During this time, Odo's shapeshifting abilities caused him to even look like Curzon- indeed, the Guardian speculated that Odo's shapeshifting abilities essentially allowed him to 'join' with Curzon much like a symbiont would with a host- and Curzon was able to reunite with Benjamin Sisko. At first, Curzon and Odo wished to remain as they were, robbing Jadzia of Curzon's memories. But after talking with Jadzia (who needed a pep-talk first from Benjamin), Curzon admitted his love for Jadzia, acknowledged he was being selfish, and returned to Dax. Jadzia assured him that they would always be together through Dax. Curzon's restored memories also provided Jadzia with a first-hand idea of the joy and freedom Odo found in his shapeshifting abilities, while giving Odo a unique insight into life as a solid, prompting him to admit that food, drink and other physical pleasures were so compelling he was amazed that Curzon had ever managed to get any work done.
