Ezri Dax was a joined female Trill, born as Ezri Tigan on the world of New Sydney in the year 2354. Ezri started her career as an assistant counselor aboard the USS Destiny, up until she was joined with Dax. Ezri was later assigned to Deep Space 9, the original USS Defiant and its successor. During the Borg Invasion of 2381, Ezri was promoted to captain and took command of the USS Aventine.

Startrek.com states that Ezri was born on Trill. However, this contradicts an on-screen personnel file.

BiographyEdit

Early lifeEdit

Ezri's mother, Yanas Tigan, was the owner of a very successful mining concern on the world of New Sydney. Ezri and her mother, who wanted Ezri to help run the family business, argued constantly.

Ezri refused to let her mother control her the way she did her two brothers and refused to join the family business. Instead, she enrolled in Starfleet Academy and studied to become a counselor. (Star Trek: Deep Space Nine episode: "Prodigal Daughter")

Joining with DaxEdit

Ezri attended Starfleet Academy Medical School from 2372 to 2374, focusing on psychology. Her final year of training was waived.

In late 2374, Ezri held the rank of ensign and served as assistant counselor aboard the starship USS Destiny. In that year, the Destiny was diverted because of a medical emergency and traveled to Deep Space 9. Upon arrival, the Destiny docked with a runabout that contained the Trill symbiont, Dax, who had been separated from its previous host, Jadzia. Jadzia Dax had been brutally murdered by Cardassian Gul Skrain Dukat, with the assistance of a Pah-wraith. The Dax symbiont was escorted by DS9's chief of security, the Changeling, Odo. Dax needed to a new host in a matter of weeks or it wouldn't survive. When a shape-shifting Founder of the Dominion impersonated Ezri's lover, Ensign Brinner Finok, and attempted to kidnap the Dax symbiont, Ezri was the first to realize that something was wrong. Soon after the foiling of the kidnapping and the capture of the Changeling, the ship was attacked by Jem'Hadar vessels. Dax's condition worsened, and needed to be joined immediately. Ezri had never wanted to be joined, but as Brinner Finok was still missing, Ezri was the only available Trill to join Dax with. Ezri agreed to undergo the joining procedure, and became the ninth host of the Dax symbiont, Ezri Dax. Brinner Finok would later be found safe in a medical supply closet, but their relationship did not continue after Ezri's joining.

Deep Space 9Edit

2375Edit

Ezri Dax 2375

Ezri in 2375

Ezri, confused by all of her new memories, sought out the one constant in her previous two incarnations—Starfleet Captain Benjamin Sisko, on Earth. Dax's host Ezri initially preferred not to be called "Old Man" by her new mentor and longtime friend, Ben Sisko. (Star Trek: Deep Space Nine episodes: "Image in the Sand", "Shadows and Symbols", "Afterimage")

Dax returned to DS9 with Sisko where she received the rank of lieutenant and position of station's counselor. She served in the position through the end of the war. (Star Trek: Deep Space Nine episodes: "Image in the Sand", "Shadows and Symbols")

After "returning" to DS9, she began counseling Elim Garak for his claustrophobia. After some time and work, they discovered his attacks were triggered by his guilt for helping the Federation attack Cardassian targets. (Star Trek: Deep Space Nine episode: "Afterimage")

Ezri fought in the Siege of AR-558. (Star Trek: Deep Space Nine episode: "The Siege of AR-558")

Just prior to the end of the war in 2375, Ezri began a relationship with Dr. Julian Bashir, who may have had unresolved feelings for her previous host, Jadzia. (Star Trek: Deep Space Nine episode: "The Dogs of War")

2376Edit

Ezri-Divided

Ezri in 2376

In January of 2376, Ezri brought the legendary Sword of Kahless into the possession of the new Klingon Chancellor, Martok, on the world of Boreth at a pivotal moment of a Klingon civil war. (DS9 The Left Hand of Destiny novel: The Left Hand of Destiny, Book Two)

In April of 2376, Dax was onboard the USS Defiant when a surprise attack by the Jem'Hadar killed the ship's new CO, Commander Tiris Jast. Drawing on the memories of Dax's previous hosts, Ezri took command and defeated the attacking Jem'Hadar. The experience made Ezri realize that she was capable of so much more now that she was joined, and made the switch to the Command Track. It also earned her a nomination to receive the Starfleet Citation for Conspicuous Gallantry.

April also saw a strain on Dax's relationship with Bashir when she began to explore the connection with her previous hosts and momentarily took on the personality of Jadzia Dax when they were making love. The incident spooked and offended Bashir who stormed out of Dax's quarters. The pair later reconciled after Bashir nearly died. (DS9 Avatar novel: Avatar, Book One, Avatar, Book Two)

Ezri and Julian traveled to the world of Sindorin to destroy the laboratory of Dr. Ethan Locken, a rogue former agent of Section 31, who was breeding an army of Jem'Hadar soldiers. (DS9 Section 31 novel: Abyss)

Ezri was given the position of first officer aboard the USS Defiant for its three-month exploratory mission of the Gamma Quadrant by the mission's commander, Elias Vaughn.

During the Gamma Quadrant mission, Ezri commanded a shuttle mission attempting to protect the Vahni Vahltupali from the debris of their shattered moon (an effort that tragically led to the mission's only casualty, Ensign Gerda Roness), mediated a solution to a caste conflict between the Cheka and Yrythny species, encountered an ancient alien artifact that actually separated her from Dax for a time, and confronted Commander Vaughn when he was letting personal desires get in the way of the mission. (DS9 Mission Gamma novels: Twilight, This Gray Spirit, Cathedral, Lesser Evil)

Upon her return to the Alpha Quadrant, Ezri found herself in the middle of the Bajoran Parasite crisis. The alien Parasites had a genetic link to the Trill symbionts and had been encountered by a previous Dax host, Audrid. (DS9 novel: Unity)

The revelations about the origins of the Parasites brought major civil unrest to the world of Trill when Ezri returned there to testify about the Parasite affair. After a radical faction killed a large percentage of the symbiont population, the Trill President, Lirisse Maz, ordered a moratorium on joining, allowing the symbionts to replenish their population.

Ezri and Julian ended their relationship soon after, when Ezri began to believe that his feelings for her were a by-product of his unrequited feelings for Jadzia. (DS9 - Worlds of Deep Space Nine novella: Trill: Unjoined)

2377Edit

In 2377, Ezri attended Starfleet's Advanced Tactical Training on Tellar. (DS9 novel: Ascendance)

2378Edit

The AventineEdit

2380Edit

By 2380, Ezri was promoted to lieutenant commander and was transferred to the USS Aventine, assigned to the duties of second officer. (TNG novel: Greater Than the Sum)

2381Edit

After the ship's captain and executive officer were killed while defending the Acamar star system from the Borg, Ezri assumed command of the USS Aventine as the highest ranking surviving officer. A week later, Starfleet Command field-promoted Ezri to the rank of captain, granting her permanent command. Ezri convinced Starfleet that the wreckage of the Columbia, discovered eight years previously by Jadzia Dax, could hold the key to understanding the Borg's new ability to travel vast distances without being detected, and the Aventine was assigned to a salvage mission. The mission was cut short after Admiral Jellico reassigned the Aventine to the fleet defending Trill against further Borg attacks. However, the Caeliar Arithon hid in the Columbia wreckage to board the ship, stole the runabout USS Seine, and opened a subspace tunnel, hoping to find his former planet Erigol, and merely found the supernova remnant now the Azure Nebula. (ST Destiny novel: Gods of Night)

This placed the Aventine in position to answer the USS Enterprise-E's distress call and assist them in defeating a Borg cube. Captain Jean-Luc Picard ordered the two crews to investigate the tunnels to find ways to mine the nebula and collapse them to prevent further Borg incursions, despite protests by Dax and several of the Enterprise senior staff who considered the tunnels to be too valuable as an exploratory tool. Ezri initially felt awkward around the Enterprise, and in particular Worf, whom she had not seen since her promotion. She also began to doubt her abilities to command a starship. Her first officer, Sam Bowers, convinced her to speak to Worf, and the two reconciled, with Worf indicating that her continued success did honor to Jadzia's memories.

Scientific analysis performed by Dina Elfiki and Gruhn Helkara determined that attempts to collapse the subspace tunnels could cause catastrophic reverberations, and the dynamics of the supernova remnant proved to thwart any attempts to create a minefield. After consulting with Admiral Nechayev and requesting reinforcements, Picard ceased production of the self-replicating mines Dax had suggested and instead had the ships focus on opening the tunnels, hoping to locate the staging area of the Borg, with the Aventine entering the first tunnels able to be opened. After the arrival of an allied fleet of several hundred ships, the Enterprise and Aventine traversed one of the tunnels together, and ended up near the Carina Arm near the median between the Delta and Gamma Quadrants, where they fought and were boarded by Hirogen hunters. When the two vessels returned to the nebula, they found a graveyard of ships from an invading force of seven thousand Borg cubes. Captain Dax, certain that the advanced weaponry of the Aventine could be of use in saving something from the Collective, set course for Earth, forcing the Enterprise to chase after. (ST Destiny novel: Mere Mortals)

Picard manages to convince Ezri to stand down and contact Starfleet for new orders. Unfortunately, Starfleet has no new orders for them, and instead gives them authorization to do whatever it takes to stop the Borg. Shortly afterward, the Titan under the command of Captain Riker appears, with Captain Erika Hernandez—long considered dead after the Columbia vanished 200 years earlier.

Dax and Hernandez worked together to devise a plan to stop the Borg by using Hernandez—now infused with Caeliar Catoms—to impersonate the Borg Queen by accessing a Borg Vinculum. Despite Picard's disapproval of the plan, Dax and Hernandez proceed anyway. Worf attempts to convince Ezri to call off the attack, but is unsuccessful.

Hernandez located a lone Borg scout ship to attack and the Aventine ambushed, disabled and boarded the Borg vessel. Ezri's plan was successful, and Hernandez accesses the ship's Viniculum, using her Catoms to impersonate the Queen. Under Hernandez's influence, the Borg turn on themselves, and half the invasion force is destroyed. However, the real Queen quickly reasserts control over the Collective and takes personal control over the scout ship. The Aventine is attacked by the reawakened scout ship, but manages to beam its strike teams back aboard. An explosive device inside the Borg scout ship is then detonated, destroying the vessel.

After the mission, Hernandez informs Ezri of a startling revelation: The Borg are the product of a botched fusion between Caeliar and humans from the Columbia who were thrown back in time in the cataclysm that destroyed the Caeliar's homeworld two hundred years prior. Ezri and Hernandez then come up with another plan to enlist the Caeliar's aid in dismantling the Collective. Although Picard initially disapproves of this plan, Riker is able to convince him otherwise.

Ezri is present on the bridge of the Enterprise to witness the end of the Borg invasion, and of the Borg Collective itself at the hands of the Caeliar. (ST Destiny novel: Lost Souls)

2382Edit

Shortly after the creation of the Typhon Pact, the Aventine was sent to assist Julian Bashir into Breen space. The meeting between Captain Dax and Doctor Bashir did not go well, as their relationship was still highly strained. (ST Typhon Pact novel: Zero Sum Game)

2383Edit

In 2383, Starfleet sent the Aventine to the Venetan Outpost V-4 to investigate Tzenkethi activity there. While on this mission, Ezri was reunited with an old classmate, Commander Peter Alden who was attached to Starfleet Intelligence. During the mission, Commander Alden's behavior became erratic and Ezri relieved him of duty. Ezri was overridden in this decision by Admiral Leonard James Akaar. Subsequently, it was revealed that Commander Alden's behavior was a ruse to allow him to more freely investigate Tzenkethi movements. (ST Typhon Pact novel: Brinkmanship)

2385Edit

After Julian Bashir resigned from Starfleet and attempted to provide a cure to the Andorians for their reproductive crisis, President Pro-Tempore Ishan Anjar ordered Dax to stop Bashir by any means necessary. The Aventine was later involved in a standoff at the Andorian border with two ships. Dax attempted to extradite Bashir from the freighter he was hiding on but the Aventine took damage due to a concealed weapon system.

Later after Bashir was returned to the Aventine, Dax, along with Simon Tarses and Sam Bowers assisted in getting Bashir to Andor, in defiance of the Federation President, the USS Warspite, and USS Falchion. After the cure was disseminated, she surrendered to her security officer, along with Bashir and Kira. . (ST - The Fall novel: A Ceremony of Losses, Star Trek: The New Generation episode: Beast of Burden)

After the Andor incident, Dax was imprisoned at the Jaros II stockade. She was visited by Christine Vale who had temporally taken command of the Lionheart and wanted to hear her side of the story. She then implored Vale to find Julian and set him free no matter the cost. While Vale promised that Rear Admiral Riker would ensure that Dax would have her day in court, Dax was not confident that would be the case. Dax felt that she, Julian, and the others had done the right thing and it was now time to pay the price. (ST - The Fall novel: The Poisoned Chalice)

Later in 2385 it was revealed that Ishan Anjar was long dead. Baras Rodirya - the man who had taken his identity during theCardassian Occupation of Bajor - was revealed to be working with the Cardassian group the True Way. Baras was personally arrested by Attorney General Phillipa Louvois and removed from office. Admiral Akaar was soon authorized by President Pro-Tempore Sipak to drop all the charges against Captain Dax. Dax was issued a commendation for her actions and reinstated as captain of the Aventine. (ST - The Fall novel: Peaceable Kingdoms)

In November 2385, she was in command when Admiral Riker, under the influence of the Cytherians, transferred his flag aboard the Aventine and ultimately took over the ship until the conflict was resolved. (TNG novel: Takedown)

2388Edit

In 2388, Ezri along with Julian Bashir, Typhuss James Kira and Helen Magnus used the runabout USS Rio Grande to meet with Andorian Captain My'ra Telek, about the Xindi. Telek gave them information on Xindi ships. The next day Julian, Typhuss, Ro Laren, Nog and Samantha Carter had a meeting about the Xindi in the hub. The Xindi wanted to start the war again, Nog didn't understand why the Xindi want to start the war again. Typhuss told everyone that he would lead peace talks with the Xindi. Kira filed for divorce from Typhuss, Kira was lonely and felt that Typhuss wasn't there for her. Ezri was at the wedding. Typhuss got married to Sam again. The next day Sam got a fast divorce from Typhuss and Kira came over to talk, Kira stopped the divorce and reconciled with Typhuss.

Later that year, Starfleet Command lost contact with Regula I after the USS Columbia was destroyed by a Elachi ship, Admiral Kathryn Janeway sent the Intrepid and a small fleet to Regula I in the Mutara sector. The Aventine was part of the fleet. Admiral Janeway came with the fleet aboard Voyager. The fleet got a distress call from the USS Stargazer, it was under attack by Elachi ships. The fleet set a course for Regula I using their quantum slipstream drives. Twelve hours later the fleet arrived at Regula I, the fleet engaged the Elachi ships. After drving off the Elachi ships from Regula I, Captain Kira lead a away team to the station with Colonel Sarah Mackenzie along with Captain Chakotay, Lieutenant Commander Tom Paris and Lieutenant Harry Kim. Soon the away team came under attack by a Human woman armed with a Klingon disruptor pistol. Captain Kira ordered Colonel Mackenzie to use a stun grenade to stun the Human. It was found that the Human woman was Cheryl Anderson, Typhuss's ex-wife and the second woman was a clone of Xena. The Voyager officers returned to Voyager, Captain Kira ordered Mackenzie back to the ship with the two women and take them to sickbay. Mackenzie beamed back to the ship and later Captain Kira beamed back to the ship.

2389Edit

The Aventine was at Deep Space 9 (II) during the peace treaty with the Xindi.

Alternate versionsEdit

During Kira Nerys' vision from the Prophets, Ezri was represented by a woman named Zeir.

Alternate timelineEdit

Ezri Dax 2404

Captain Ezri Dax in 2404 of an alternate timeline

In an alternate timeline, the Federation was at war with the Klingon Empire in 2400. In 2403 after the war was over, the Federation Starfleet was destroyed and was replaced by the new Bajoran Starfleet. Ezri joined this new Starfleet with Kira. The United Federation of Planets became the United Bajoran Federation of Planets. By early 2403 Bajor was succumbed to numerous but unsuccessful raids by the Klingon Empire. Bajor had built a large fighter wing division which would defend the planet from the pathetic attempts from the Klingon Empire in attacking the Bajoran homeworld.
