Description Edit

Built in the mined-out husk of a metallic asteroid, Omega has been a haven for criminals, terrorists, and malcontents for thousands of years. At times the station has lain idle and abandoned for centuries, only to be reactivated by a new group of outlaws seeking a fresh start. The space station's original elegant design has given way to haphazard expansion by scrabbling factions of every species. There is no central government or unifying authority on Omega, and nobody can recall a time there ever was one.

  • Population: 7.8 million
  • Orbital Distance: 2.43 AU
  • Orbital Period: 6.9 Earth Years
  • Total Length: 44.7 Km

Codex EntryEdit

Originally an asteroid rich in element zero, Omega was briefly mined by the Protheans, who eventually abandoned it due to its thick, impenetrable crust. Thousands of years later, nature did what even the Protheans could not: a collision with another asteroid broke Omega in half, exposing its trove of element zero for easy mining.

A rush ensued as corporations and private individuals tried to strike it rich on Omega, and thieves and outlaws followed in their wake. As space became tight, construction of processing facilities extended vertically from the asteroid, creating Omega's jellyfish-like silhouette. To prevent future collisions, the station is ringed with enormous mass effect field generators that redirect incoming debris.

Today, Omega is a major hub of narcotics, weapons, and eezo trafficking without even a pretense of civilian government or military control. Only mercenary groups have been able to instill a limited order; the most ruthless is an asari syndicate run by the notorious Aria T'Loak.

History Edit

Omega - The Mines
Omega is described as "the Terminus Systems' dark, twisted counterpart to the Citadel." It is a huge mining station built from the remains of a massive, irregularly shaped asteroid with twisting streets populated with homes, shops and warehouses. Omega's inhabitants are usually lawless. Territory is controlled by the strongest faction in that area and frequently changes hands, often after brutal violence. The station's current "de facto" ruler is Aria T'Loak. As of 2185, Omega has a population of 7.8 million people, composed of various different species. The station's major export is element zero.[1]

The earliest known ruler of Omega was a turian; he controlled the station until he was killed by a krogan crimelord who ate his heart and wore his skull on his armor. The krogan reigned over Omega undisputed for a time until some 200 years ago, when Aria T'Loak, once one of his most trusted lieutenants, defeated him in single combat and usurped him.

The heavy-metal-rich core of the original asteroid was mined until the asteroid was almost completely hollow, providing the initial resources used to construct Omega's buildings and facilities. Over the years, these have been expanded until they completely cover every exposed inch of its surface, making Omega a bizarre mishmash of architecture and technology. The station is home to dozens of species, including batarians, vorcha, and Lystheni salarians, as well as many other species not welcome in Citadel space.

While humans refer to it as Omega, the asari name for it translates as "the heart of evil", the salarian name as "the place of secrets", the turian name as "the world without law", and the krogan name it as the "land of opportunity", clearly reflecting their cultural attitudes towards the society within Omega.


Mass Effect: Ascension Edit

Cerberus controls a large warehouse and smuggling operation at Omega in 2183, led by Pel, a Cerberus operative. Pel finally betrays Cerberus, leading to the deaths of all of his team, and there has been no word about the warehouse since.


Mass Effect: Redemption Edit

Liara T'Soni hitches a ride to Omega on a batarian freighter in order to meet an informant with news of the then-missing Commander Shepard. Liara learns from Aria that Shepard's body is being taken to the station's lower levels, at an old mining processing plant, as part of a transaction between the Blue Suns and the Shadow Broker. A brief scuffle at the area ensues over possession of Shepard's body, resulting in explosions, moderate fire damage, and a lot of mercenary casualties.


Mass Effect 2 Edit

In 2185, Commander Shepard travels to Omega to recruit Mordin Solus, Garrus Vakarian, and Zaeed Massani. At the time, a plague is ravaging Omega's populace, killing dozens of people from various races but mysteriously sparing humans. Elsewhere, a vigilante called "Archangel" has been cornered at his base by Omega's three dominant mercenary factions: the Blue Suns, Eclipse, and Blood Pack.

Shepard meets with Mordin Solus, a salarian scientist and former STG operative who runs a clinic in one of Omega's slums. The plague is revealed to have been caused by the vorcha, who aligned with the Collectors in order to take over the station. Using a cure for the plague developed by Mordin, Shepard stops the outbreak and foils the vorcha scheme.

Shepard later signs on with the Blue Suns as a freelancer in order to help the besieged Archangel. After taking a Blue Suns advance force by surprise and discovering Archangel is actually Garrus Vakarian, Shepard and Garrus fight off the last waves of the merc attack and escape. News reports after the fact indicate that the merc groups covered up their defeat, and claim that Archangel had been killed. During the course of the mission, Shepard also learns that the three merc groups planned to try and topple Aria's regime after getting rid of Archangel. Shepard can pass this information on to Aria, who can be found on a balcony overlooking Afterlife.


Mass Effect: Retribution Edit

In 2186, Paul Grayson lives on Omega and works for Aria T'Loak as an enforcer under the alias "Paul Johnson". Grayson gradually gains Aria's trust through the efforts of her daughter, Liselle, who has become Grayson's lover. Grayson, Liselle, and more of Aria's enforcers ambush a group of turians belonging to the growing Talons mercenary group and take red sand which the Talons had been smuggling on the side.

Later, after being implanted with Reaper technology, Grayson returns to Omega to meet with Kahlee Sanders, which turns out to be a trap ultimately set by the Illusive Man and permitted by Aria, who thinks Grayson killed Liselle and wants revenge. Grayson is wounded in the attack but manages to escape Omega.


Mass Effect: Invasion Edit

Omega comes under attack as Reaper creatures called Adjutants break loose from Cerberus's research bases beyond the Omega 4 Relay and invade the station. A Cerberus fleet led by General Oleg Petrovsky and Colonel Raymond Ashe arrives and helps eliminate the Adjutants. The Adjutant attack turns out to be only a prelude to an attempt by Cerberus to conquer the station and secure exclusive access to the Omega 4 Relay and its treasure trove of Reaper technology. Aria unites Omega's warring gangs to fight against the Cerberus occupation force, but General Petrovsky outsmarts her by taking the entire station hostage and threatening to destroy it level-by-level. Aria surrenders and accepts exile. Cerberus proceeds to take control of Omega, furthering the Illusive Man's plans to counter the Reapers.


Mass Effect 3: Omega Edit

Omega defense cannons
The occupation of Omega gave Cerberus a huge strategic advantage during the Reaper invasion of 2186, bolstering their mobility throughout the Galaxy. Cerberus would overuse the mining facilities of Omega, pushing the mining equipment of the asteroid to its limits. Cerberus had difficulties maintaining the occupation, however. The Talons gang led by Nyreen Kandros is one of those groups still able to resist the occupation. In order to contain the civilian population, General Oleg Petrovsky erected large energy-intensive force fields throughout the station along with a large number of mechs and troops to maintain order.

Cerberus also conducted experiments with the Reaper-based adjutants in Omega. Initially this proved to be disaster. Large sections of Omega had to be shut down and sealed at a great cost of lives to contain outbreaks of uncontrolled Adjutants. Further experimentation would give Cerberus a full control of these creatures.

Aria begins her campaign to liberate Omega from Cerberus, having enlisted Commander Shepard in the process. Traveling aboard a captured Cerberus cruiser in order to infiltrate the Cerberus fleet surrounding the station, Aria opens her attack with a crippling blow to the fleet's flagship as her own fleet charges in via mass relay. The tables are soon turned, however, as Petrovsky reveals Omega's upgraded defenses by proceeding to inflict heavy damage on her fleet.

The initial invasion force lands on the station in escape pods. Aria and Shepard first disable Omega's defenses in order to give the invading fleet a chance. Later, with the help of Nyreen Kandros, they fight their way to Aria's Bunker on Omega's D-Deck, where Aria decides that in order to get to Petrovsky's command center in Afterlife, she needs to rally the Talons gang to her cause to supplement her ground forces, and disable the force fields that Cerberus has set up.

Omega - mines reactor
Cerberus is siphoning power for the force fields from one of Omega's main reactors deep within its mines. As access to it is mostly cut off by the force fields, Aria devises a plan to go through a powered-down eezo processing plant. Navigating the mines, Aria notices the machinery's overworked condition and estimates a month before they give out if the current trend continues.

Aria and company eventually reach an elevator to the reactor's back door, although General Petrovsky traps the squad in more force fields in anticipation of the move. Aria is not to be outdone, and forcibly opens a hole in the barrier for Shepard to pass through and disable the reactor.

Petrovsky dishes out another difficult dilemma at the turn of events: immediately shutting down the reactor will cause loss of life support in a lot of Omega's areas, which translates to loss of civilian lives. Taking the time to reroute the power increases the chance of Aria and Nyreen dying as they're still holding their own against endless waves of mechs in the trap. Regardless of choice Shepard disables the reactor and ends the forced internal blockades.

Omega - mad prophet 2186
With the Talons recruited, the populace incited, and the force fields down, the true war for Omega begins as the civilians revolt against Cerberus. Aria and Shepard prevent Cerberus from destroying Omega by blowing up the station's central support column, then join in the offensive to Afterlife from the Gozu District. Nyreen, who had been leading a separate assault with her Talons, sacrifices herself to kill a group of rogue Adjutants. Enraged at Nyreen's loss, Aria charges into Afterlife ahead of Shepard.

Afterlife has been repurposed by Petrovsky in the course of making it his base of operations: the General traps Aria in a stasis field at the center of the establishment, powered by generators positioned at the corners. Shepard breaks her out and defeats all the Cerberus forces in Afterlife.

Defeated, Petrovsky surrenders himself and orders his troops to stand down, but Aria and Shepard decide whether he should be spared or executed on the spot. With Omega hers to rule once more, Aria announces its liberation to the citizenry, and vows to never lose the station again.

Districts Edit

Omega is divided into several districts. Known districts include:

  • Doru District - A district located near several vital Omega utility systems, including a water treatment facility, the main ventilation system, and the station's central support column. Cerberus fortified the area during their occupation in 2186.
  • Fumi District - A district the Talons raided to free civilians during the Cerberus occupation of Omega in 2186.[2][3]
  • Gozu District - A residential area in the lower levels of Omega accessible by shuttle, notable for being the location of the Omega Clinic. Once policed by the Blue Suns, the district fell into chaos after being quarantined to prevent the spread of an unknown plague in 2185.
  • Kenzo District - A district where Garm and the Blood Pack were allegedly carrying out a large gun running operation in 2185. This turned out to be a ruse set up by Sidonis for Archangel so that Omega's gangs could attack Archangel's hideout.
  • Kima District - Another residential area that borders Gozu District. The vigilante Archangel and his team occupied a building in Kima District in 2185 where they were cornered by the Blue Suns, Eclipse, and Blood Pack.
  • Tuhi District - A commercial area filled with shops and businesses, including Tuhi District Storage, that is located near Aria's Bunker. Cerberus fortified this area during their occupation in 2186.
  • Zeta District - A district where Cerberus deployed Rampart Mechs during their occupation in 2186.[2][3]
