Earth

Planet Earth (or simply Earth) is Beatrice's home planet that is located in the Milky Way.

Background
Millions of years after the earth's creation, it went through an Ice Age, which covered 80 percent of the planet, creating an underground world protected by the Sheets of ice. Down the road, Humans would find the preserved Jurassic world and make peace with the dinosaurs, later dubbing the underground Diatopia.
