Mars

Mars, the fourth planet from the Sun is the second most populous world in the system. Often referred to as the red planet, her people are viewed as industrious and collectivist having long since developing into their own post-human clade. Mars is also famous for its terraforming project centuries in the making and its nascent biosphere which its inhabitants view with a spiritual reverence.

Hellas Planitia
One of the great centres of Martians civilization, the terraforming project has allowed a shallow sea to begin to emerge in the great impact crater of the Hellas Republic.

Valles Marineris
Home to the largest canyon in the solar system, the behemoth gash in the surface of Mars was the first place on the world to be peopled and is now the most populous region of the planet, with three-quarters of all Martians dwelling within. A young river system has begun to form in its depths. Three separate republics form the territory of the Mariner Valley.

Agyre Planitia
Sister republic of Hellas the Agyre basin is smaller than the growing Hellas sea but possesses its own nascent ocean.

Tharsis
Sparsely populated but economically powerful, the region known as Tharsis is home to a plethora of titanic volcanoes among them, the largest in the solar system: Olympus Mons. The power-base of the Republic of Tharsis is its control over the Pavonis space elevator through which the plurality of the off-world traffic must pass through.
