- Dominion slogan(src)
As planet after planet appealed to the Sons of Korhal for aid after the collapse of the Terran Confederacy, Arcturus Mengsk announced that a new government was necessary to protect these worlds. Promising victory over the zerg and the protoss, he formed the Dominion and crowned himself emperor. One of his first decrees was to begin reconstruction of Korhal, electing to make it the throne world of the Dominion.
Over time, the Dominion's heavy-handed tactics began to resemble those of the Confederacy, and it became increasingly oppressive.
Even though many of the Dominion's founders from the Sons of Korhal spent hard time in New Folsom Prison during their rebellion against the Confederacy, the Dominion continued to use it. Every scientist, philosopher and free thinker that challenged Mengsk's rule was incarcerated in New Folsom.
Mengsk reinforced the armies of the Dominion by forcefully conscripting the remaining Confederate warriors, then set out to fortify the various worlds under his care. A permanent defense force was stationed on Agria, which became one of the Dominion's principal botanical and wildlife preserves.
The Amerigo was infiltrated by Kerrigan, who accessed the Dominion network and located records of the Ghost Program, allowing her to learn about their mental conditioning that kept her psionic powers in check.
When Tassadar violated Dominion air-space and endangered human lives in an attack against the zerg, Duke ordered Tassadar to withdraw his ships immediately or he would open fire upon his vessels. Upon receiving what he assumed was a hostile response, Duke sent in his fleet and was defeated by Tassadar.
Alpha Squadron was also dispatched to deal with notorious smuggler Alan Schezar and his Scavengers, leading to further mysteries when the Dominion discovered that Schezar could somehow control zerg. The detachment broke away, disobeying orders in order to assist the protoss in putting an end to Schezar's zerg threat, but Schezar escaped.
After the fall of Aiur, Alpha Squadron was dispatched to aid the colonists of Bhekar Ro. The squadron suffered heavy losses fighting over a xel'naga temple against both the protoss and zerg and was cut off from the Dominion for months afterward.
The Terran Dominion was also involved in a war to retreive a powerful xel'naga artifact, the Argus Stone from the planet Aridas. The Dominion intended to use it as a military weapon. Although the planet was technically a Terran Dominion outpost, the arrival of protoss and zerg forces made things complicated. Jenson Archimedes was in charge of the Dominion expedition that clashed against the protoss and zerg, and after various battles the Dominion managed to retreive the Stone from a protoss stronghold on the planet. However, in an effort to recover the Stone, the Zerg Crusaders destroyed Archimedes' battlecruiser escort, then pursued him through multiple Dominion bases. The zerg captured some of his allies, infesting them in order to gain information on Archimedes' whereabouts. The zerg eventually stole the Stone from Dominion forces, who allied with the protoss and followed the zerg all the way to Char, only to be defeated.
The Brood WarEdit
- Main article: Brood War
Boralis was assaulted by a United Earth Directorate strike force. Although the city was well defended, the command center was destroyed after Lieutenant Samir Duran of the Confederate Resistance Forces showed them an alternate route that led to the rear of Boralis. Soon, the Dominion's primary datanet was accessed by the UED.
Confederate Resistance Forces officers Samir Duran and Angelina Emillian used this information to plot an assassination attempt on Arcturus Mengsk while he was visiting Umoja. Mengsk was hampered by Umojan distrust; they demanded he keep his capital ships beyond the outer shipping markers, forcing him to descend in an obsolete gun cutter. The Confederates used a Cassandra scrambler to cut Mengsk's communications off from his fleet and an EMP net to cut off communications with local Protectorate defense forces. However, the assault was a failure, in part because Dominion Fleet leader Edmund Duke disobeyed Umojan instructions to stay away when communications were cut off. Mengsk learned the term "UED" but did not learn what it stood for. Not knowing how the Confederates were able to target him so effectively, Arcturus Mengsk believed the Umojans were complicit in the attack.
The bulk of the Dominion's battlecruisers were commandeered by UED soldiers at the Dylarian shipyards. Duke led a Dominion fleet against them from the Norad III, but was defeated by the their newly acquired fleet. The Dylarian shipyards were destroyed and Duke withdrew his forces from the quadrant. The remnants of Dylar IV's defenders were conscripted into the UED.
After a fierce battle, Augustgrad was besieged by the UED. Mengsk held back their advance for as long as he could, but was forced to contact the UED fleet from the Norad III requesting a parlay with Admiral Gerard DuGalle. He was rescued by Commander Jim Raynor and they escaped via dimensional recall.
Kerrigan offered to help Mengsk reclaim Korhal from the UED if he loaned her his psi emitters. On Braxis, the psi emitter was carried by a Dominion SCV and helped Kerrigan to gather up nearby zerg, which she used to tear down the psi disrupter.
After the UED forces occupying Augustgrad were overwhelmed by Kerrigan's zerg, a jubilant Mengsk sent Duke to establish his base of operations in Augustgrad. The next morning, Duke's base was attacked by multitudes of zerg while most were asleep and unaware. The base was destroyed and Duke was killed. Warfield wasn't present due to his privileged status in Mengsk's eyes. Mengsk denounced Kerrigan for her treachery, but she responded that her actions were well-justified revenge and left him on Korhal.
Mengsk scraped together a new fleet and attacked Kerrigan's base of operations on Char Aleph alongside the remainder of the UED fleet and a protoss armada. Facing imminent defeat, Mengsk withdrew early in the battle, telling Kerrigan to watch her back because he would be lying in wait for her, ready to strike when she inevitably made a mistake.
Following the Brood War, the Dominion's military was still weak. It was unable to deal militarily with problems such as the New Trinidad Pirates, eventually resorting to hiring mercenaries to destroy them. Still, at least according to propaganda, the Dominion was quickly able to (re)establish its military and economic might. Mengsk's control of the media allowed him to keep his atrocities (both past and present) hidden from the public. Most of the Dominion populace accepted Mengsk’s rule, believing him to be the only leader capable of protecting them from the alien threats in the Koprulu sector. Mengsk asserted that humanity’s only chance to survive the dark days ahead was to be united under his leadership, whether by choice or by force.
By the next war, the Dominion had time to build several large fleets with more advanced technology, as well as increased its knowledge of the zerg.
Although Warfield retired in 2501, the Dominion rose again to become the most powerful force among the terran factions. It took over almost all of the original Confederate worlds, including Braxis, where it rebuilt its fortifications. Over the next four years, the Dominion extended its influence throughout the Koprulu sector.
Vast fortunes were lavished on the cleanup and rebuilding of Korhal, although portions of the irradiated desert were left untouched in honor of those who died in the Confederate bombardment. The planetary defenses were massively increased, and Mengsk turned Korhal into the most heavily fortified planet in the sector.
The second most heavily defended location in Dominion space was Skygeirr Station, where the Dominion had help from Doctor Emil Narud in combining protoss and zerg DNA were to create hybrid creatures of immense power. A bio-weapons lab orbiting Castanar on a captive asteroid was also used to breed the hybrid. Mengsk planned to terminate everyone who ever worked there.
Mengsk's oppressive rule and powerful position made him the target of many terran revolutionary groups. Foremost among them were Raynor's Raiders. Mengsk used the media and propaganda to marginalize Raynor's efforts and portray him as a terrorist, along with making general efforts to exterminate the rebels. Vast amounts of Dominion weapons and hardware were stolen by Raynor's Raiders. Mengsk spent trillions of credits on keeping them constantly hunted and harried, denying them any chance to gain a respite and build their strength.
Shiloh came under noticeably increased surveillance by Dominion military forces, which only heightened the agitation of the colonists. It was unclear whether the Dominion was trying to flush out potential seditionists like Raynor or presenting a show of force to discourage any imitators.
Cognizant of the fact that the Umojan Protectorate remained ideologically opposed to the Dominion and was widely considered a safe haven for individuals seeking refuge from persecution by Mengsk's forces, the Dominion took measures to undermine the sovereignty of Umoja and its affiliated worlds by imposing trade embargoes and making assassination attempts against dissidents pursuing asylum in Protectorate territory.
In 2503, Dominion marines engaged a heavily armed group of pirates on Agria to protect its valuable hi-tech scientific equipment, carelessly slaughtering colonists who were caught in the crossfire.
Dominion scientists in at the Tyrador III research facility were assigned to create elite, cybernetically enhanced military units. Egon Stetmann sabotaged the facility and made his escape amid the confusion and smuggled himself off Tyrador III aboard a merchant ship.
The Dominion engaged in an economic conflict with the Combine. The latter would sabotage Dominion operations. In an attempt to "simplify" relations, Mengsk sent ghosts to kill Victor Kachinsky.
The Ghost ProgramEdit
The Dominion would eventually become involved in a public relations clash with the Umojan Protectorate over the fate of its ghost recruits. Senator Corbin Phash of Maltair IV secretly harbored a psychic son, Colin. The secret was revealed when the planet was attacked by the zerg. Only the two Phashes survived. Corbin Phash took shelter with the Protectorate, but Colin was captured and inducted into the Ghost Program. The Protectorate found itself under a Dominion economic blockade, raising the price of food. The Dominion even tried to assassinate Corbin Phash, but Phash survived the attack.
The Dominion turned to public relations to defend its use of ghosts in order to counter propaganda made by former Senator Phash and spread by the Protectorate.
The Dominion's most significant military development project since the end of the Brood War was Project: Thor, a (formerly) secret superweapon system. Umojan agent Ulli Trey infiltrated the testing facility, bringing the information to the Umojan Protectorate. The Protectorate planted evidence, blaming the attack on the anti-Dominion faction, the Koprulu Liberation Front.
The Dominion ordered the destruction of minor terrorist groups.
In 2501, the Dominion closed down Project Shadowblade, a ghost-enhancing program which used terrazine, a psionic reagent, to enhance the powers of ghosts. The results were called spectres. However, numerous problems arose, causing the project to shut down.
Shadowblade survivor and Nova Squadron commander Jackson Hauler, under the guise of General Cole Bennett, hatched a plot with spectre Gabriel Tosh, AI Lio Travski, the Umojan Protectorate, and some "lesser" players suchas Michael Liberty. They intended to use the spectres to kidnap Arcturus Mengsk and place the Dominion under Hauler's command. The revolution failed, however, and Hauler and most of the spectres were killed.
The Heir Apparent and the Search for ArtifactsEdit
Arcturus Mengsk's son, Prince Valerian Mengsk, was secretly named the "Heir Apparent" to the Dominion. Valerian commanded high authority over the few who knew his true identity. The prince became interested in an alien artifact on the dead world of Nemaka, and hired an archaeologist, Jake Ramsey, to look in on it. Ramsey discovered a secret there, but when Valerian's marines on the Grey Tiger imprisoned him, Ramsey fled with R.M. Dahl to the world of Dead Man's Rock, which was outside of Dominion space. The zerg attacked shortly afterward, drawn by Ramsey's discovery. Arcturus Mengsk considered this invasion as an attack on the Terran Dominion. The Dominion temporarily came into possession of a protoss treasure trove as a result of the conflict.
Conflict with Raynor and Mar SaraEdit
Dominion official Tamsen Cauley, however, in part of a scheme to increase his own power, recruited a band of outlaws, the War Pigs, to assassinate Raynor. He formed an army which was "not Mengsk's. Not the Dominion's" — the Cerberus Program, which he would use to kill the War Pigs once they murdered Raynor. (The War Pigs had been a Confederate team which Cauley used in those days to try to kill Arcturus Mengsk.) Raynor managed to escape Cauley's wrath.
The Dominion showed a renewed interest in the Sara system and established several outposts there. For months, Dominion engineers excavated an alien artifact at White Rock Base. The Dominion forcibly shipped citizens there from Backwater Station to dig it up. Mengsk made it illegal to trade in alien goods.
Wings of LibertyEdit
Dominion forces set up a logistics headquarters in Backwater Station, which become the hub for all operations on Mar Sara. Not long after the Dominion pulled troops out of the city, Raynor destroyed the logistics headquarters with help from the locals, inciting an open revolt against the Dominion.
As the Dominion was getting ready to move the artifact off-world, Raynor's marines destroyed White Rock Base and seized the artifact. Mengsk declared that anyone found in possession of the artifact would be dealt with to the fullest extent of the law. Meanwhile, a Dominion jorium freighter was hijacked by pirates.
The Dominion was invaded by the zerg. Mengsk pulled the fleet back to the protect the core worlds, abandoning the fringe worlds, including Agria. Mengsk declared new austerity measures and reactivated Warfield, who began 'Operation Burnout' to clear the Sara system. The First Fleet took part in the operation as the core worlds were fortified. Massive refugee fleets struggled to reach the safety of the core worlds. The death toll soared due to shortages of food and water.
Conscription stations opened across the core worlds after the Kel-Morian Combine was defeated by the zerg.
A Dominion weapons plant on Nephor II exploded, causing a chain reaction that took out several housing complexes in a working-class neighborhood. Dominion Security claimed it was an act of terror by Raynor, but investigations by the Universal News Network suggested that the plant had been infiltrated by rogue Dominion ghosts.
Refugee fleets decreased as various fringe worlders started new colonies and declared themselves independent of the Dominion. Mengsk tightened security measures. There were food riots on the fringe worlds.
As refugees continued to flood Dominion space, Mengsk ordered the fleet to turn away refugee ships that entered core-world systems.
New Folsom was broken open by Tosh with the assistance of Raynor's Raiders. The Dominion's highest-value prisoners were freed, including former members of Project: Shadowblade and a number of political dissidents. Dominion Security Forces were put on high-alert.
The Dominion held firm under zerg aggression. Its industrial complex stepped up production on all fronts, enlistment rates rose within the penal system, and the Dominion Marine Corps was soon ready to start pushing the zerg back.
The Dominion placed Tarsonis under strict quarantine while its salvage teams sifted through the rubble for any Confederate technologies and military secrets that may have survived the zerg assault. Mengsk promised the scattered refugees that Tarsonis would be restored and the Dominion would help guide it toward a brighter future. They restored power to the old rail network and ran a large number of supply trains with minimal security. They found Adjutant 23-46, but as they transported it to the processing station, their trains came under attack by Raynor's Raiders. The Dominion responded by sending escorts to protect the trains, attacking Raynor's base, constructing a series of bunkers to protect the tracks, patrolling the tracks with large groups of marauders and boosting their trains' speed. However, they failed to keep Raynor's troops from retrieving the adjutant.
With zerg sightings all over the Dominion, the First and Second Fleets combined to defend the core worlds.
The Odin was commandeered by Tychus Findlay in the testing facility on Valhalla. Communication with Korhal was blocked long enough for all Dominion bases in the area to be taken out by Raynor's Raiders. Meanwhile, Mengsk declared a moratorium on interplanetary travel.
The Dominion unveiled the Odin at the UNN Studios and were confused when it fired on the studio guards. The Dominion switched to a secure channel so that Captain Matt Horner could not track their positions. Warfield sent strike teams Alpha, Bravo and Charlie after Raynor's Raiders, but they were unable to prevent them from broadcasting proof that Mengsk used psi emitters on Tarsonis. Mengsk's approval rating dropped to a record low of fourteen percent and citizens rioted in the streets of Korhal, setting fire to government buildings to express their shock and anger at the revelations. More arrests followed the broadcast. Bountiful declared independence. Before Kate Lockwell could begin a ten part expose on corruption in the Dominion government, the newscast was terminated by order of Dominion Security.
Valerian and Warfield left half the Dominion Fleet to Char, accompanied by Raynor's Raiders. The zerg launched a spoiler attack and the few battle-groups that made it to the surface scattered all over the place. Warfield's ship took terrible, terrible damage and crashed. Raynor rallied the survivors, secured a landing zone and rescued Warfield.
The xel'naga artifact was assembled and the engineer corps moved it to the base of the primary hive cluster. Raynor and Warfield entrenched the last of their defenses all around it before using it to make Kerrigan human again.
Heart of the SwarmEdit
For the next three weeks, Mengsk's forces carried out a relentless hunt for Kerrigan. Nova led a raid on Research Station EB-103. Dominion insertion teams were held off by Umojan marines while the facility was evacuated. Nova's forces captured the security hub and put the facility on lockdown, but Kerrigan and Raynor managed to reach the shuttle bay, where the Archangel was deployed. It was destroyed by Kerrigan, but Nova managed to capture Raynor. Mengsk announced to the Dominion that Raynor was dead when in fact he was taken to the Moros, and Mengsk took every precaution to ensure that no one reached him.
The Dominion Fleet attacked the Hyperion above Phaeton, refusing to cease fire even when Horner told them that Valerian was aboard, as Mengsk was willing to sacrifice anything to kill Kerrigan. A Dominion ground team set up a Drakken pulse cannon on the surface with orders to eliminate any stragglers as they warped in. They found Kerrigan in a zerg base, but she held them off until Broodmother Naktul arrived. The cannon was destroyed by Kerrigan and Naktul's brood, at which point the Dominion troops fled to their ships.
When Broodmother Zagara attempted to bring her brood through the Bone Trench, Warfield brought in a Gorgon which strafed them repeatedly. However, Warfield's forces retreated when Kerrigan brought down the Gorgons by awakening scourge nests. When Warfield's compound on the Dauntless Plateau came under assault, he activated his nuclear arsenal. Kerrigan survived the blast and proceeded to destroy the fortress. Although Kerrigan killed Warfield, he convinced her to let three shuttles packed with wounded men go.
The Dominion launched thousands of two-way communicators at Kerrigan's leviathan. Mengsk used one to contact Kerrigan and reveal that Raynor was alive. He told her to keep her Swarm away from Korhal or Raynor would be killed.
Colonel Orlan hacked the Dominion's deep-encryption security network and found out where they were holding Raynor. When the Moros stopped at Atlas Station for resupply the next day, it was boarded by Kerrigan. In response, Mengsk set the bridge to explode. The Moros then began tearing itself apart as Kerrigan reached the prison deck, but Dominion soldiers were unable to prevent her from getting Raynor out.
Kerrigan was drawn to Skygeirr Station by Alexei Stukov and the garrisons on the platorm were infested. The Dominion vented gas onto the platform to kill the infested terrans, then attacked the virophages. Once their gas reserves ran out, it required time to synthesize more gas and they came under renewed attack by the zerg. The entrance to the facility was breached and Dominion forces inside failed to prevent Kerrigan from destroying the laboratory.
With zerg leviathans assembling above Korhal, Mengsk called upon his forces to defend it. Dominion fleets converged on Korhal and troops arrived from all over the sector, but they were held off by a blockade of leviathans under Broodmother Kilysa. On the surface, Mengsk sent the Sons of Korhal and the Night Wolves to eliminate Kerrigan, but they were unsuccessful. The Drakken defense network was destroyed by bile launchers and Dominion forces were driven into Augustgrad.
The Dominion deployed a Psi Destroyer and launched a diversionary assault. However, it was destroyed by Kerrigan and Dehaka while the zerg under Zagara pushed the Dominion into the Imperial sector.
The Dominion's elite attempted to defend Mengsk's palace from the zerg and Raynor's Raiders. Mengsk sent Sky Fury Squadron, Alpha Squadron and the Odin to destroy the Hyperion, but they were unsuccessful. Inside the palace, Mengsk caught Kerrigan off guard with the xel'naga artifact, but Raynor intervened and saved Kerrigan, allowing her to kill Mengsk personally.
A New BeginningEdit
- Valerian Mengsk(src)
Following the death of his father, Prince Valerian assumed the throne. He set out to rebuild the Dominion and pledged to abolish the oppressive laws that had existed under his father's reign. Most of his time was spent trying to reign over a Dominion that had fallen into chaos. A new system of social justice was developed.
In regards to foreign relations, Valerian would be proactive, making overtures for a military and technology exchange alliance with the Umojan Protecterate, while also declaring a general cease-fire with Hierarch Artanis, halting all agressive action against protoss of the Daelaam.
While going through his father's records, Valerian came across the existence of Project Blackstone. He dispatched a battlecruiser and the science vessel Brin to the Blackstone facility to rescue the surviving scientists. He offered them continued (and paid) service for the project, using the science vessel as their mobile base. He conversed with Dr Talen Ayers and wanted to make him head of he project. He promised to do what he could to find Ayers's missing daughter.
A New WarEdit
During the rebuilding effort of Valerian's regime, contact was lost with the Moebius Foundation. The last transmissions received from them were crazed and chaotic. In 2506, the Moebius Corps started showing up on Dominion worlds and indiscriminately destroying them, lead by hybrid.
The Dominion counterattacked, but were forced to defend Korhal when a massive Moebius Corps fleet appeared in orbit and began besieging the planet. Commander Jim Raynor, newly appointed Admiral Matt Horner and Valerian Mengsk coordinated a defense, and were reinforced by Hierarch Artanis and the Daelaam. Artanis had come to retrieve the Keystone from Korhal Palace, but proceeded to help defend the planet from Moebius Corps. The space platform Sky Shield had its atmospheric generators disabled by Moebius Corps, and the platform began plummeting into Augustgrad. The Daelaam supported Dominion repair crews, and the platform was stabilized.
Meanwhile, Moebius Corps raided Korhal Palace and stole the Keystone, preparing to take it offworld from Bennet Port. Raynor and Valerian organized a force to retrieve it, and were supported by Artanis. The hybrids leading Moebius Corps channeled void energy into the Keystone, causing a shockwave that stunned all terrans on the battlefield at regular intervals, but leaving the hybrid and protoss unharmed. The combined terran and protoss force pushed to the Keystone and repelled Moebius Corps and their hybrids from Korhal, but at a heavy loss of life.
In the later stages of the End War, the Golden Armada, under the influence of Amon, began purging Dominion worlds. The Dominion organized its fleet to fight this new threat, but was not able to field much resistance.  Eventually, the Golden Armada pulled back to Aiur after the Daelaam began attacking Amon's host form directly. 
After Amon was purged from the galaxy, Kerrigan called the Daelaam and Dominion together to push into the Void to destroy Amon once and for all. Commander Raynor and Admiral Horner organized the Dominion wing of the force that aided Kerrigan, and helped slay Emil Narud in order to free the trapped xel'naga Ouros. When Kerrigan needed to channel Ouros's essence to become a new xel'naga, the Dominion under Raynor were key in organizing her defense.  Finally, in the final confrontation against Amon, Dominion forces pushed the void crystals protecting him, allowing the newly ascended Kerrigan to destroy him once and for all. Amon's death signaled the end of the End War, but only after untold devastation to the Dominion.
By 2508, Valerian's Terran Dominion had entered a golden age of peace and prosperity. This same year, Valerian declared that open elections would be held within the Dominion. A ceasefire was declared with the Daelaam and Zerg Swarm.
On the third anniversary of the fall of Arcturus Mengsk, Admiral Matt Horner asserted the continued support of the Dominion military of the new regime. Peace talks between the Terran Dominion and Daelaam continued between the two governments. Commander Jim Raynor vanished, and was never heard from again. However, as the Swarm claimed Char and the surrounding systems, the ceasefire between the three races of the Koprulu sector was called into question.
Soon however, documents confirming Valerian's connections to the Moebius Foundation and their hybrid were found by the Umojan Protectorate, and threatened to break the trust Valerian had gained from his people. Valerian ordered Agent Nova Terra to infiltrate an Umojan Protectorate space fortress named the Keep to retrieve the documents. Nova was successful in getting in, destroying the Keep's defenses and retrieving the documents before reinforcements arrived. Valerian, now with the offending discs in hand, expressed regret for being complicit in the hybrid breeding program, and Nova told Valerian that memories and secrets can be buried but that does not make them disappear. Pondering that, Valerian then released the documents on his connections to Moebius publically, stating that he had failed his people, but he would keep no more secrets from them. Nova meanwhile refused to undergo a mind wipe of the mission to the Keep, in spite of wishing to forget the civilians she killed.
Having survived zerg attacks and intercine strife, the Dominion's war-weary populace attempted to recover from previous conflicts. Many people were eager for peace, but a conflict of interests arose between members of the population, and how they even operated in a time of peace was a question asked. Some people wanted to make sure that the Dominion remained ready for any future alien attacks, and that they had the security and weapons needed to protect themselves. Others were more interested in ensuring that Valerian's government took a more progressive, egilatarian direction. Valerian showed himself to be a fairer ruler than his father, and allowed freedom of the press. However, that same freedom allowed his enemies to question his actions with impunity. One anti-Dominion faction that arose was the Defenders of Man, secretly united under Dominion General Carolina Davis (a Mengsk family loyalist). Several Dominion ghosts, including Nova Terra and Stone, were loaned to the Defenders of Man.
During this strife, the Zerg Swarm were spotted on outer colony worlds, including Antiga Prime. Unbeknownst to the Dominion, these attacks were orchestrated by the Defenders of Man, who used psi-emitters to lure feral zerg to undefended worlds. Admiral Horner affirmed that this was an isolated incident, with Valerian Mengsk stating that the Dominion was not at war with the zerg. Relief effort was sent to the Antigan population. Meanwhile, a large number of Terran Dominion ghosts began to go missing. However, attacks on Bountiful and other outer rim colonies were met with slow response, and the Defenders of Man were the ones to repel the zerg there. This turned public opinion against the Dominion in favor of these militias, and the Dominion Senate began discussing the group. It remained deadlocked on the question of use of military action.
Ghost agent Nova Terra was assigned to investigate the activities of the Defenders of Man. However, her and a number of other Dominion ghosts went missing shortly after. Radio Liberty attempted to investigate, but their offices were raided by masked attackers, and two of their crew were taken hostage. Going on the hints of Michael Liberty, listeners of Radio Liberty broke into the Defenders of Man database and uncovered Ghost academy files on the missing ghosts, as well as evidence stating Nova had killed undercover Dominion agents in that base. These files were sent to Matt Horner, who promised a Dominion response to the situation.
Attacks continued across the outer colonies, with slow Dominion response leading to disillusionment with the Valerian Mengsk regime and support of the Defenders of Man. Nova broke out of a Defenders of Man base, and reconnected with Admiral Matt Horner on Borea, where he told her that she was wanted for treason. Just then, the zerg attacked Borea. Nova organized a defense, but Defenders of Man battlecruisers arrived to save the colony, and demanded the Dominion withdraw and surrender Nova. Horner used the chaos of their attack to escape the planet with Nova.
Nova and Valerian Mengsk met, and Valerian gave Nova the Griffin as well as his Covert Ops Crew. She met Reigel, who used a device to make her memories of her time in the Defenders of Man resurface. These lead her and her team to Tarsonis City. After setting up a garrison, Nova infiltrated a Defenders of Man facility, where she discovered their plan to use psi-emitters to destroy Tyrador IX, thus exposing Valerian Mengsk as a weak ruler.
The Defenders enacted their plan to send the zerg to Tyrador IX, and planted a psi-emitter on its surface. The feral zerg overran the world, destroying the Dominion defenses and killing a massive amount of civilians. Nova's Covert Ops Crew moved in to intervene, and attempted to first take care of the zerg. The Defenders of Man sent their fleet to aid the civilians. However, during the conflict the Death Fleet of the Tal'darim arrived, intending to destroy the Defenders of Man. Nova, knowing that the Tal'darim would kill the civilians they were defending in the process, set out to destroy the shield projectors defending the mothership. She was successful, and First Ascendant Ji'nara sent the mothership at the Dominion position. Nova and her crew were able to destroy the mothership and repel the Tal'darim and saved thousands of lives. However, the Defenders of Man took credit for the rescue. Massive protests began outside of Korhal Palace, calling for Emperor Valerian Mengsk to step down.
Nova however found an unlikely ally; Highlord Alarak boarded the Griffin and made her a deal. He would give her access to terrazine, which would undo the mind wipe the Defenders of Man did to her, and in return she would lead him to the Defenders of Man. Nova agreed, and moved her forces to Jarban Minor. There she rescued the Umojan Protectorate survivors trapped there, and fought both the infested terrans and the Tal'darim under Ji'nara who sought to challenge her for the substance from the Jarban gliders. Nova gathered what terrazine she needed, and Alarak said when she found what he desired he would know. With that the two parted ways.
Nova then contacted Valerian, who urged caution. He eventually had to cut contact as the protests outside of the palace began to worsen. Nova injected a microdose of terrazine, and remembered working with the Defenders of Man on an operation on Antiga Prime. Nova went there, fighting through the feral zerg that occupied the planet. Using the terrazine, Nova remembered her part in planting the psi-emitters and working for the Defenders of Man, and working with Stone to uncover what the devices they were planting were. Nova then found the mission files Stone had left behind. After injecting one last dose of terrazine, she uncovered a memory of the Defender of Man's leader, General Davis.
Nova contacted Valerian, telling her what she found. Nova wanted to assassinate Davis, but Valerian stated he had a plan, and Nova would need to play her part in it. Valerian then contacted Davis, stating his intention to step down as Emperor of the Dominion.
This was however a ruse to draw Davis out, and Valerian announced he would give his speech to step down on Vardona. Meanwhile, Nova would sneak in through the sewers, infiltrate Davis's compound, and capture her. Nova did so, but on the way discovered Delta and Pierce in holding pens, with their memories wiped. Reigel said he would send a team for them. After unlocking the doors to Davis's office, Nova confronted Stone, who had also been mindwiped. Nova incapacitated her old squadmate, and ordered Reigel to extract him as he was still alive. Nova then moved into Davis's chamber, and apprehended her. She was brought before the Emperor, who was giving a speech to the people of Vardona. Valerian stated that he had proof the Defenders of Man were behind the zerg attacks, and that it was engineered by Davis.
However, as Davis was brought out in handcuffs, the Tal'darim Death Fleet arrived to exact vengeance on the Defenders of Man. Their ships strafed the city, killing Defender of Man, Dominion soldier and civilian alike. Nova insisted that Alarak should not be able to harm civilians, and came to the city's defense. The Dominion ground forces, Nova's Covert Ops Crew, and low ranking Defenders of Man unaware of Davis's plans formed a defensive line against the Tal'darim, and held back their advance. Soon Admiral Matt Horner called in the Dominion Fleet, who used Gorgon-class battlecruisers to strafe the Tal'darim lines. In spite of sending motherships against the terrans, the Tal'darim were beaten back with high casualties and forced to retreat. However, in the chaos General Davis escaped aboard the Medusa. Nova and the Griffin gave chase.
Nova tracked Davis to the Cerros Shipyards, where she and her loyalist Defenders of Man planned a last stand to destroy the Dominion Fleet's stock of Gorgons, hampering Valerian's ability to control the Dominion. Nova stated that she had to kill Davis, but Valerian demanded that she be brought back alive. Davis activated a top secret war machine named the Xanthos, and attempted to use it to beat through the defenders and destroy the Gorgons. Nova was able to destroy the Xanthos's weapon systems, forcing it back for repairs, and she and Admiral Horner's Hyperion were able to break through the Defender's final lines. When the got to the Xanthos however, Davis revealed a top secret transformation mode that activated a large thermal beam. However, neither that nor sending the remaining Defenders of Man against the Dominion forces were successful, and the Xanthos was incapacitated. Nova went inside, and against Valerian's direct order killed General Davis. 
Nova, now a fugitive, fled Dominion capture. Reigel noted to her that he and the crew were loyal to her first and foremost, and Nova intended to use the crew as a vigilante group in the defense of the Dominion, doing so on their own terms. Peace returned to the Dominion, as Valerian released documents on the Defenders of Man's plans, popular support returned to Valerian, even regarding the assassination of General Davis. Horner tracked the Griffin, but Valerian told him to let Nova go, for now.
Scars of the WarsEdit
By 2512, the Terran Dominion was still struggling to rebuild from the wars of the 2500s. Though a tenuous peace had been won, famine and drought had broken out across many of the planets undergoing reconstructing. Planets that took severe damage were economically draining the healthier ones. There were also a vast number of physically and psychologically scarred individuals from the wars that it was struggling to provide for. The Dominion sought aid from the Umojan Protectorate, but as they still saw the Dominion as a threat they were hesitant to supply aid.
Unexpectedly a call for aid came from the Zerg Swarm, who called Emperor Valerian Mengsk to the planet of Gystt, a supposedly purified planet that had been regrown by the zerg. There Overqueen Zagara met with Valerian and Hierarch Artanis, stated that Sarah Kerrigan had gifted them the essence of the xel'naga before she departed, allowing them to regenerate world such as Gystt. They spun these into creatures named adostra. However, Abathur saw these creatures as abominations, and the peace between races as contradictory to the goals of the Swarm. He engineered a second species named the chitha, who used xel'naga essence to disrupt psionics and communications. Though he nearly succeeded in destroying the adostra nests and sparking a war with the powers of the Koprulu sector, the Dominion's survey team eventually discovered his plot and destroyed his chitha, allowing Zagara to apprehend him.
In the fallout of the One-Day War, peace talks began between the Daelaam, Zerg Swarm and Dominion. The Dominion founded the Zerg Compliance Ground-Force Unit to oversee the peace between the races, and would help aid in the hunting down of chitha, the guarding of the adostra and the prevention of Abathur from sparking another conflict.
Reign of Arcturus MengskEdit
Under Arcturus Mengsk, the Dominion was an absolute monarchy, though this was a fact that he tried not to reinforce.
Internally, the Dominion ruled through oppression, fear and surveillance and makes extensive use of propaganda in order to control its citizens. It has outlawed "crimes" such as hitchhiking and squatting, banned the airing of "subversive" music, and was somewhat corrupt. Externally, as Mengsk once put it, "tyrants can only survive by presenting a greater tyrant as a threat." The Dominion maintained a somewhat aggressive stance towards its neighbors. Groups such as the Umojan Protectorate and the UED Expeditionary Fleet remnants were labeled as "racial traitors" in propaganda and the zerg and protoss were portrayed as distinct threats. The Dominion claimed that it was the only effective defense against the Swarm; a force that during the years after the Brood War, it claimed was dormant, though many within its military structure knew otherwise. The Dominion's predecessor, the Terran Confederacy, was also demonized. For the citizens of the Dominion, anything alien was a threat to be reported to the authorities.
Reign of Valerian MengskEdit

Under Valerian Mengsk, the Dominion continues to make use of propaganda, stating that the old tyranny of Arcturus's rules has been abandoned. It claims that Prince Valerian and the senate have established "the most enlightened and least corrupt governing body in history," along with calling its social justice system "the envy of the sector." The zerg remain the Dominion's primary enemy, and protoss motives continue to be questioned. It has accepted that conflict with terrans is also likely—such is the nature of human history.
Valerian allowed freedom of the press.
