Earth (Terra)

Earth, otherwise known as Terra or Gaia, is the only naturally terran planet located in the star system Sol. It is the birthplace of Humanity and has been the center of Human civilization for millennia, from the conception of advanced society in 7,000 B.C.E. to the first steps out of the solar system in 3,000 A.D.

It was the victim of biosphere sapping for over 4,000 years from hostile forces beyond the limits of human civilization.
