Omega

Location: Milky Way / Omega Nebula / Sahrabarik

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

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
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 around the 1980s CE, 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
