/tg/Station 13

The year will be the current one plus 540 years, as we do for the /tg/ server, simply because it's easy to remember.
Credits is the currency and the language is Sol Common. WY doesn't exist and neither does the US. Consider it to be in the same universe as /tg/ but with a slightly more 'serious' tone.

Who we're fighting for

The Sol Confederation, colloquially referred to as SolCon, is the main governing body and who the marines directly work for. The Sol Confederation Colonial Marines (SCCM) force is a military organisation, overseeing the defence of Sol and its colonies. Marines are typically pooled from Sol, who benefit from full citizienship, but may be recruited from the core and outer colonies, who possess limited citizenship. Serving in the SCCM on a green card basis grants full citizenship.
Due to the vast distances between each colony, many of them can be considered autonomous but most generally acknowledge the Sol Confederation's legitimacy, those that don't are either annexed or become separatists. Non-Humans are rare to non-existent in SolCon space, and the SSCM's official recruitment policy is strictly Human-only. Those possessing genetic modifications are disbarred from service and not declaring the existence of such during or after recruitment is grounds for dismissal.

Nanotrasen is a gigantic, multi-system spanning megacorporation and a "generous sponsor" of the SSCM. Nanotrasen has a number of businesses but their most well-known product is plasma and is essential for practical space travel. NT also supplies the SSCM weapons, appliances, Artificial Intelligences and even the spaceships they operate on. This affords Nanotrasen many rights and privileges from SolCon, much to the dismay of smaller organisations swept away by the waves of the megacorporation. It's an open secret that NT consider the SSCM to be just another franchise of theirs in all but name.
'Officially', NT do not supply the SSCM with energy weapons or any second-generation 'smart' AIs, instead, it sells them (by their standards) outdated ballistics, slower-than-light travel drives and non-sentient first-gen AI systems. NT has many detractors, opponents, critics but it also has just many people who sing their praises and their terraforming initiative for SolCon colonies is too invaluable to simply ignore.

Who we're fighting against
Xenomorphs
As far as the general public are concerned, Xenomorphs do not exist. However, the SSCM are both aware of their existence and are regularly informed of such by Nanotrasen due to irregular encounters with the species. The SSCM are aware of their capabilities but where they come from is not known. The SSCM and Nanotrasen's official policy is to secure, sterilize and retrieve any samples for further study or destroy them if that is not possible. Nanotrasen are especially eager in their desire to study due to their ability to naturally produce plasma and may 'pressure' the SSCM to acquire samples at all costs.

The Syndicate
Terrorists of the 26th century and rabidly opposed to both Nanotrasen and SolCon, for their apparent corporate whoredom. The Syndicate isn't so much one group, as a load of groups, each vying for power. Various companies (mostly those unable to compete with Nanotrasen), criminal families, and paramilitary groups make up what is known as "The Syndicate". Some Syndicate members aren't even human according to various rumours. The SSCM's official stance on the Syndicate is that they are violent terrorists and the SSCM does not negotiate with terrorists. Marines are encouraged to report anyone they suspect of being a member of the organisation to their superiors, or their superior's superiors in extreme cases.

The Union of Soviet Socialist Planets (USSP)
The revived remains of the Soviet Union and a rival to the SolCon government. Relations between both governments remain frosty at the best of times and is equally as active as SolCOn are in colonizing the frontier, though they lack the terraforming technologies that NT have granted them. There is no official conflict between SolCon and the USSP, there have been minor skirmishes but such engagments have never escalated beyond that. Though, some may think that the 'cold war' between the two powers may grow hot any day now...

Others
Space is a big place and big players like the SSCM and Nanotrasen are bound to make a lot of enemies, some whisper of Clown terrorists armed with pranks and buffoonery the likes the Universe has never seen...
