Lampetia is a distant planet outside of Earth's solar system, the birthplace and residence of the stars and constellation's human avatars, and the residence of Corona Austrina and Corona Borealis. It is shown to be an idyllic and fantastical world with unique architecture and abstract natural beauty. There are no animals, and the only living beings besides plants are the personified stars and constellations.

It is very strongly implied that Lampetia was a creation of Corona Borealis and Austrina, who are regarded by its inhabitants as goddesses in their own right for giving the stars and constellations life, bodies and personalities.


  • Lampetia's name is derived from the name of the Greek goddess of light, the daughter of Helios and Neaera. Her/Its name literally translates to "shining", an apropos name for a planet inhabited by personified stars.
