The Dominion is one of several playable factions in Star Trek Online. It is a major galactic political power based in the Gamma Quadrant, whose influence is exerted over thousands of planets there. It was created by the Changelings, a species of shapeshifters native to a rogue planet within the Omarion Nebula, who refer to themselves as "The Founders." The Dominion's subject worlds are kept in check by Vorta administrators and formidable Jem'Hadar soldiers.

Player Characters[edit | edit source]

Since the release of Victory is Life, players can create a Jem'Hadar character. Regardless of other characters on that account, Jem'Hadar characters start at level 60. Like other factions' characters, Dominion players must choose a career (analogous to a 'class' from other MMORPGs) and a species (or race). Neither can be subsequently altered. Later, when the player reaches a higher rank, a starship must also be selected, which can, however, be changed at any time.

At the end of “Turn the Tide”, players also have to choose an ally, the Klingon Defense Force or Starfleet. Jem'Hadar characters will retain their UI as well as their exclusive costumes. However, they cannot build their own fleet starbases and will instead be able to join fleets and teams, as well as visit social hubs of their chosen ally.

Classes[edit | edit source]

See main article: Profession

In Star Trek Online when creating a character, players must choose which permanent career path they wish their character to adopt. Players are able to currently choose from the three careers below. Each profession has its own advantages (and, of course, disadvantages) in the game play of Star Trek Online.

Unlike other playable factions, Jem'Hadar characters come with certain career-specific startup unlocks, which can, however, be either developed further over time or altered by spending premium in-game currency, or in some cases for free, to match those of any of the three careers below:

Races[edit | edit source]

Dominion characters are far more limited than other factions in terms of available races, due to the unique structure of the Dominion's military. Players can choose from the freely available Jem'Hadar and premium (purchasable) Jem'Hadar Vanguard with additional space combat bonuses.

Starships[edit | edit source]

See main article: Dominion playable starships

Jem'Hadar players get one free Tier 5 vessel as well as a fighter, and can choose from a variety of other paid-for starships as well as vessels of the faction they choose to align with after “Turn the Tide”.

Each starship has numerous sub-types for different ranks and styles of play, and each of those sub-types with a number of cosmetic variants.

Jem'Hadar characters may also fly almost any ship of their respective ally - the Federation or the Klingon Empire. Ally ships which are unusable by the Dominion players are:

Storyline missions[edit | edit source]

Faction Dominion.png Dominion Storyline Episodes

Once “Turn the Tide” has been completed, the player must complete the Gamma Quadrant story arc before being able to replay standard Federation and Klingon Defense Force storyline episodes depending on their allegiance. The game refers to any episode prior to Turn the Tide as a simulation.

Culture[edit | edit source]

Absolute rule of the Dominion remains in the hands of the Founders and their Great Link, whose decisions cannot be disputed under any circumstances. However, the Founders are largely content to leave the administration of the Dominion's daily affairs to the Vorta. The loyalty of the Vorta and the Jem'Hadar is genetically-engineered, which in most cases ensured absolute obedience to the Founders. The Founders themselves are rarely seen, even by their servant races, and are often treated as gods or myth. Due to such a social standing within the Dominion, most of what the Dominion's member races carry out are often for the glory of the Founders, or to please them in some way, similar to how religious figures would pray or carry out an action to please their god(s).

The Dominion prefers to eliminate threats through influence and espionage, only launching military strikes when the usual tactics are unsuccessful.

History[edit | edit source]

Origins[edit | edit source]

Thousands of years ago the Changelings were a peaceful people who explored the galaxy much as Starfleet does today. However, they were persecuted by the "solids" they encountered, and eventually retreated to their homeworld in the Omarion Nebula. From there they founded a vast interstellar empire intended to remove or subjugate all potential threats to the Changelings and impose order on the galaxy. The Vorta, initially a race of tree-dweeling primates, were genetically uplifted to become the Founder's administrators.

Shortly after its formation, the Dominion made contact with the Hur'q. Believing them to be perfect candidates for a warrior race, aside from pacifism, the Female Changeling removed a fungus from their homeworld's ecosystem during a hibernation period, intending to offer the Hur'q a choice between subjugation or death when they next awoke. Unfortunately, this led to the fall of the Hur'q civilization.

2,000 years ago, genetically manipulated Klingons were intended as a soldier caste and became known as the Fek'Ihri. However, the Dominion's plan to control them via addicting them to Ketracel White failed. Eventually, the plan worked with the Jem'Hadar, who became the Dominion's front line soldiers instead.

Over their history, the Dominion subjugated hundreds of races including the Dosi, Karemma, T-Rogorans, and Yaderans.

At some point in their history the Changelings sent 100 infants to explore the galaxy and return to share what they had learned. Among them were Odo and Laas.

Dealings with the Alpha Quadrant[edit | edit source]

In 2370, the Jem'Hadar destroyed a number of bases and starships from the Alpha Quadrant that had unknowingly entered Dominion territory through the Bajoran wormhole. Among these were the New Bajor colony and the Federation starship U.S.S. Odyssey.

Following the initial hostilities, the Dominion began using espionage to destabilize the Alpha Quadrant. Changeling infiltrators replaced key members of numerous Alpha Quadrant powers and influenced them to attack each other. These infiltrations were responsible for a number of large-scale conflicts including the Klingon-Cardassian War, the second Federation-Klingon War, and the Battle of the Omarion Nebula.

In 2373 the Dominion established a foothold in the Alpha Quadrant by allying with the Cardassian Union, and began bringing large fleets of warships through the wormhole to fortify their strength there.

Open War with the Alpha Quadrant[edit | edit source]

Determined to prevent any more Jem'Hadar forces from entering the Alpha Quadrant, Captain Benjamin Sisko of Deep Space 9 placed thousands of self-replicating mines at the entrance of the wormhole. The Dominion responded by sending a fleet of 300 Jem'Hadar and Cardassian warships from Cardassia Prime to attack the station, eventually capturing it. Sisko and most of his senior staff escaped on the U.S.S. Defiant and regrouped with Starfleet and the Klingon Defense Force.

Though the first few months of the Dominion War in 2374 were marked by several crushing defeats for the Federation Alliance, the re-taking of Deep Space 9 (with the help of the Prophets, who removed a fleet of 2,800 Jem'Hadar warships in the wormhole) turned the war around for the allies.

Later that year, the Romulan Star Empire discovered evidence that the Dominion planned to violate their non-aggression pact and invade Romulus. As a result, they joined the war against the Dominion.

The following year, Section 31 infected the Founders with a morphogenic virus to weaken the Dominion's leadership. Becoming desperate for a quick victory, the Female Changeling negotiated an alliance with the Breen Confederacy. Breen technology proved to be very effective against the Alliance: in the Second Battle of Chin'toka, more than 300 Federation, Klingon, and Romulan starships were destroyed. Fortunately, Starfleet was eventually able to develop technology to counteract the Breen weapons.

Meanwhile, Legate Damar had become disillusioned with Cardassia's costly alliance with the Dominion, and formed a resistance movement. With the combined efforts of the Federation Alliance and Damar's rebels (the ranks of which now included the entire Cardassian military as well as most of Cardassia's civilian population), the Female Changeling finally surrendered at the Battle of Cardassia and the war ended. Odo cured her of the virus, and returned to the Gamma Quadrant to distribute the cure to the rest of his people. The Female Changeling was taken into custody and held at Facility 4028.

The New Link and the True Way[edit | edit source]

See New Link and True Way for more information

While the powers of the Alpha and Beta Quadrants would have little to no contact with the Dominion in the Gamma Quadrant anymore for the following decades, Laas forms a New Link in the Alpha Quadrant. Independently from and unbeknownst to the Great Link in the Gamma Quadrant, he allies himself with the True Way and conscripts the services of the Alpha Jem'Hadar.

Hur'q re-emergence[edit | edit source]

At some point during the latter half of the 2400s, the Female Changeling realized that the Hur'q would be re-emerging from hibernation in 2410, and that they would likely be close to unstoppable this time around. To head off the threat before it could impact the Dominion, she secretly journeyed to the Alpha Quadrant and replaced Tzenkethi Fleet Admiral Aarn Tzen-Tarrak. She then proceeded to manipulate the Tzenkethi Autarch into declaring a crusade against what were called Drantzuli. As many of the planets the Hur'q had hibernated on were in unclaimed space, the crusade went unnoticed, until the Lukari vessel L.S.S. Concordium and an Alliance starship chanced upon Draconis III, one of the planets targeted during the crusade. Tzenkethi forces led by 'Tzen-Tarrak' clashed with the Alliance over Jod'Cor, New Kentar, and Dranuur. At some point during these battles, the Hur'q in the Gamma Quadrant re-emerged in earnest and began attacking anything in their path. Many Dominion worlds bore the brunt of their assault, such as Ennis and Karemma.

In the Alpha Quadrant, things came to a head in the Bajor system when a Tzenkethi fleet, having learned that Bajor apparently was a Hur'q hibernation site, launched a massive offensive against Alliance forces there. Unbeknownst to either side, however, Odo, having realized that the Dominion would not be able to deal with the Hur'q threat by themselves this time around, had arranged for a Hur'q lure to be placed on Bajor, thus drawing the aggressive insects there when those in the Alpha Quadrant awoke and alerting the Alliance to the real threat. A fleet led by Odo then traveled to the Alpha Quadrant to assist Alliance forces in the defense of Bajor. During the battle, Dominion forces aided 'Tzen-Tarrak' in escaping from the Tzenkethi battle station that had been brought in over Bajor.
