General Development

High

Earth is the third planet from Helios and the executive-judicial capital of Vangelia. The homeworld of humanity, it is the only place in the galaxy where the two currently extant human species, neohumans and retrohumans, are found together. It is also a major trading hub, straddling multiple interregional starways. Despite its importance, it has a small population of 3 billion, most of its inhabitants having died thousands of years ago in a cataclysmic war. After the Vangelian Revolution, neohumans settled the planet while upholding the rights of its endemic retrohumans.
