Earth

Earth is the native homeworld of the human species. The planet currently lies mostly in ruins except for the City, which was rebuilt following extraterrestrial assaults. It currently lies under the protection of the Traveler.

Earth is continuously under attack by various alien species. With the help of the Traveler and its mystical powers, the Guardians protect Earth and strive to recover its conquered areas.
