Úros

Úros is an exoplanet approximately 2.55 million light years away in the. It is the second planet from its star, Porios. It is a super-Earth with a mass over 3 times that of Earth.

Etymology
The name comes from Ancient Lithon Uurasx, meaning "the light big/expansive one"

Characteristics
Úros is much like Earth in many ways. It has oceans of liquid water, mild atmospheric conditions, and plenty of land. However, no complex life ever developed on Úros. The land is barren and empty, and the only creatures in the ocean are microscopic pseudobacteria called Boiri.

Lithon presence
the Lithoi have a long and storied history on Úros. The Phelithon even had a presence on this planet, and today their ruins scatter the surface. Some alive today have been on Úros for 20 thousand years or more, and many were created here. These and other Lithoi live in huge megacities across Úros, as well as in vast mines under the surface.
