The Setting
It is the early part of the 23rd Century.

Mankind was pushed to the edge of extinction as rising water levels and global temperatures vastly reduced the habitable regions of Earth. Depopulation and growing desperation forced mankind to expand outwards across the solar system throwing up colonies in habitats previously thought impossible for mankind to survive in.

Nanotech, biotech and enhanced bioengineering have given humans the ability to live under the harsh dome cities of Mars or in deep space satellite habitats (SHs, self-sufficient contained environments). Ironically parts of the Earth have also recently been reclaimed for human habitation. Exposure to solar radiation and unnatural habitats has left a lasting mark, accelerating and initiating the fastest period of human mutation and perhaps evolution.

History

Early 2100s:
Tipping points are breached in the Earth's climate, melting the polar ice caps and overloading the remaining carbon sinks sending the planet into an escalating cycle of global warming flooding most of the Earth’s land area. Technological advances allow for the people of Earth to expand off Earth, initially to the ring a gigantic constructed habitat crossing the equator to maximise solar energy collection. It becomes a prototype test bed for hundreds of satellite habitats (SHs) and a launch platform for for Lunar and Martian colonisation. More than half of the current SHs and all the Lunar and Martian colonies were built or started in a very short 30 year period (known as the Exodus) from 2130-2160 all under an enforced 60yr period of Martial Law by the Unified Earth Govt. (UEG).

5yr War
2161 March 9th – Martian colonies and 1/3 of the 300 or so SHs declare independence in a coordinated move to try and break away from the UEG. The resulting conflict is long but largely bloodless (apart from minor skirmishes and several notorious incidents – destruction of SH277 on Bloody Thanksgiving). The difficulties of making attacks across interplanetary distances negates the UEG’s superior numbers. Eventually a truce is declared and the UEG collapses due to a lack of key mineral sources (mostly all mined off Earth). The DEC (Democratic Earth Collective) replaces the UEG and makes a lasting peace and trade agreements with the independent nations on 2166 – March 9th (CID - Colonial Independence Day).

Planets, Cities, Satellite Habitats

Earth:
Population – 400m; half are terrestrial, mostly in poles or underground in highland areas. Most of the rest live in the ring. Floating and underwater cities are the newest expansion and house a small but growing proportion of the population (currently 10%). Another 10% live in Lunar bases. The DEC controls the Earth and moon and Earth Ring but is hugely divided by its varied constituencies.

Mars:
Six colony cities were established in the Exodus and have expanded downwards after filling their domes. The economy is based around energy and mining exports. Energy is the limiting factor and so the currency consists of ECs (Energy Credits).
After the 5yr war the Martian cities squabbled over control and after some bitter infighting each colony went over to self rule. Each has a slightly different setup and mines different minerals from various patches in their area (they are positioned with 4 along the equator and one at each pole so as to maximise solar energy collection). Each city is orbited by a spaceport.

Martian Dome Cities:
Freedom (Alpha-1) is a 6 level metropolis (5 underground levels) containing 50million people, covered by a dome of immensely thick semi-transparent and very dense super alloy. It has a 50km radius to and reaches 5km at its the highest.
High City – towers and other elevated dwellings under the dome; 1m people, has its own interconnected street tunnels and mini transport network.
Low city – street level with 17m people in very cramped conditions. This level is divided into different regions from upper middle class all the way to ghetto areas. It contains Orbital Launcher Facility (overlaps with small part of High City).
Lower Level 1: suburban expansions – populated by dwelling facilities 12m.
Lower Level 2: deep enough to have undergone massive excavation mostly for housing 10m.
Lower Level 3: industrial and support facilities, 5m.
Lower Level 4: support level for the mining activities on level 5, 5m.
Lower Level 5: geothermal power plants and mining facilities, negligible housing due to geographic instability and poor living conditions due to mining.

Alpha-2, 3, 4 (Liberty, Independence, Choice): all similar to alpha-1 in setup and most have about 50m people apiece. Each is governed by a Ruling Council (6 Mayors and 6 Council Reps) and a Governor (10-year terms; 2 max). All are on 10-year terms and so the Mayors tend to be wealthy business tycoons.

Satellite Habitats (SHs, 700 in total)
300 established in the Exodus with more added gradually over time. Most orbit some mass (a few are free floating or change orbits regularly). Most are fully artificial although some are built into asteroids or small planetary bodies (usually converting them into ‘hulls’). Many are affiliated with bigger local players, such as a larger SH or governing association.

Information on Interplanetary Propulsion
Ion Drive:

The development of the Ion Drive facilitated efficient travel between the various planets of the Solar System.
Current advances now allow for the speeds of about 300,000km/h to be achieved with the best engines or approximately 1 A.U. (astronomical unit / day). Thus trade and cargo ships travel now daily between the planets that which are closest to the Sun all the way out to Mars. Travel to those colonies and SHs located further away also occur regularly but with less frequency due to the added expense.

Antimatter Drive:

The fastest mode of space travel is facilitated by antimatter drives. These are able to theoretically achieve travel of the order of fractions of light speed. However their practicality is severely limited by he prohibitive cost of generating antimatter and the technical challenges and risks associated with handling the material.
