Terra Nova is an Earth-type planet which colonised by mankind in the 6th millenium and was once the pride of the United Earth Government's colonies. However, an economic collapse forced the UEG government to abandon Terra Nova and all its other colonies centuries before the period depicted in the game setting, leaving Terra Nova in a dark age. Eventually, City-states rose from the ashes and either through treaties or tyranny, united to form national unions called Leagues. These Leagues would in turn ally (again either peacefully or forcibly) to form the superpower blocs that dominated the temperate southern and northern hemispheres of the planet. The planet's geography is primarily land containing deep underground water reserves, but few large bodies of open water, and no oceans. This is unlike Earth which is covered by 70% ocean. The planet has its own existing ecosystem of plants and animals, though most animals are reptilian in nature, such as the bison like Barnaby used as livestock, and the prolific Hopper which is the equivalent of Earth's rabbit. The single dominant land feature is a massive mineral rich, hot, desert belt around the equator of the world known as the Badlands. This territory is not dominated by any one political group, and is considered open territory to everyone, and contains many bandit groups known as Rovers. Most people live in the northern or southern polar regions where temperatures are more acceptable to human life, and other terrain types such as forests, grasslands, swamps and jungles can be found. Small ice caps with arctic conditions and glaciers are found on the true north and true south poles.
