The main star of the Sirius system (Sirius A) has a white dwarf companion (Sirius B) on an elongated orbit that brings it to within nearly 10 AU of the primary roughly every 50 years, with such close passages in 2993.

Planetary Info

Sirius V

The planet Sirius V has a chill, subzero hydrogen-methane atmosphere that makes for a yellow-green sky.[34] Red mud and ice-rimmed pools of liquid ammonia are mentioned.[34] The surface temperature rarely raises beyond -40 centigrade, and the gravity is 1.5g; the planet was settled almost a century after the research station on Sirius VI-a, to exploit its considerable resources of heavy metals and transuranic minerals.[34]

Sirius VI/VI-a

The first settlements on Sirius were actually on Sirius VI-a, the moon of the last planet, as it had a breathable atmosphere. It wasn't until around fifty years later that the resource-rich but oxygen-poor planet Sirius VI was colonized. Throughout the Succession Wars, the terraforming that allowed the settlement of Sirius VI was slowly reversed, until the only habitable area was the domed city of Calgary. The capital city of Sirius VI-a, Lost Hope, was located on the Bounty continent, one of two main continents on the moon. Bounty and the other major continent, Hinterlands, would become home to the bulk of the population in the Sirius system.[1]

System History

Early History

Terran Alliance explorer Alana Korvin DeVall founded the Sirius colony[35] in 2167[2]. Upon its discovery, Sirius was considered a poor colonization candidate, due to its hostile atmosphere and frequent seismic activity, but its vast mineral wealth encouraged the adventurous (and desperate) to seek a profit. In 2200, the major mining corporations finally decided to move in, and began terraforming Sirius with oxygen factories and sulfur-eating algae.[2] Sirius was one of the systems that remained a part of the Terran Alliance following the Outer Reaches Rebellion and the Demarcation Declaration of 2242,[3] and became one of the worlds within the Alliance Core region of the Terran Hegemony.[9]

By 2300, the atmosphere had become breathable, and Seismic Suppressor Stations were constructed, designed to sense an approaching earthquake and prevent it through underground explosives. Despite this use of advanced Hegemonic technology, surface disruptions prevented the construction of any terrestrial manufacturing centers. Instead, orbital factories were constructed, along with twin habitation colonies known as "The Projects." Each station could house 10,000 workers in Terra-like comfort.[2] Whilst Sirius VI continued to be plagued with chronic earthquakes and volcanic activity and remained a water-poor world, the mining colonists on Sirius VI and the settlers on Sirius VI-a developed a symboitic relationship, and travel between the two dwarfed the traffic with other systems in terms of frequency. The Projects were an interesting waypoint for those traveling between the two.[1]

During the Amaris Civil War, the Rim Worlds Republic destroyed The Projects without reason, killing 8,000 colonists. A further 9,000 were killed on the planet's surface when Republican forces stripped the planet of its resources and prevented the shipping of any further supplies.[2] The blockade resulted in widespread starvation on Sirius VI.[1]

Succession Wars era

After the fall of the Star League, the planet fell under the control of the Capellan Confederation, but lacking the Hegemony's technological know-how, the oxygen factories have since started to fail, forcing much of the population to evacuate the planet.[2] Many of the planetary settlements on Sirius VI were torn apart by seismic activity, and conditions on the planet steadily worsened; control of the Sirius system was fought over by the Confederation, the Free Worlds League and later the Federated Commonwealth.[1]

Third Succession War

In 2901 the Tenth and Fourteenth Marik Militias were responsible for conquering Sirius for the Free Worlds League.[19]

As of 3028, Sirius was described as a "fairly important world on Liao trade lanes".[36]

Tiantan massacre

Sirius V was raided by the Gray Death Legion (in the employ of House Marik and the Free Worlds League) in early 3028. Following the surrender of the capital city of Tiantan, rogue elements posing as the Gray Death Legion detonated demolition charges at the city's domes and marched BattleMechs through the ruins, killing some 17 million inhabitants with the intent of blaming the atrocity on the Gray Death Legion.[37]

Fourth Succession War

Following negotiations between Colonel Pavel Ridzik, chief military advisor to Chancellor Maximillian Liao, and AFFS Lieutenant General Ardan Sortek, conducted in February 3029 Ridzik created a new nation, the Tikonov Free Republic. The Republic was created by incorporating those worlds of the Tikonov Commonality that hadn't already been conquered during the first half of the Fourth Succession War. Ridzik returned to Elgin, the new capital of the Tikonov Free Republic, on the 3rd of March 3029 and swiftly began implementing a new government consisting of family members, friends and other appointees loyal to himself, purging dissident elements on the various Republic worlds and taking the opportunity to settle old scores. Sirius was one of the systems incorporated into the Republic.[21]

FedCom Civil War

By the end of the FedCom Civil War and the demise of the Federated Commonwealth Sirius VI had been rendered almost completely uninhabited, the world having become a wasteland of a broken, shifting landscape intercut with rivers of volcanic lava.[1]

Jihad

During the third week of June 3069 the worlds of Berenson, Irian, Procyon and Sirius were rocked by internal conflict as Free Worlds League Loyalists clashed with local government forces as a result of the local governments turning against the false Thomas Marik and the government on Atreus.[38]

The Dark Age

The Sirius system was incorporated into the Republic of the Sphere; the bulk of the population in the system lived on Sirius VI-a, scattered in small farming communities across the two major continents. Calgary remained the last population center on Sirius VI, huddled on the banks of the Sulfur Sea.[1]
