Earth

"The cradle of humanity - a world of ancient glory, waiting to be retaken."

- In game description

Earth is the homeworld of the human species and is one of four terrestrial planets in the Solar System.

Overview
"Once our cities lit the whole world. Now we huddle under the shadow of the Traveler, in the last place it protects. It is so very fragile, this small blue ship, our home"

- Grimoire description.

In the wake of the Collapse, most of the planet's surface lies in ruins except for the Last City, which was built beneath the Traveler's protective aura. Earth is continuously threatened by various alien species who seek to claim it for their own ends. With the help of the Traveler's Light, the Guardians fight to protect humanity's home and retake its lost lands.

History
In the time before the Traveler, Earth had begun to suffer from overpopulation, and had become overcrowded.

The planet became occupied by the Red Legion during the Red War.
