Polis Massa

Polis Massa was once an arid, barren planetoid and the origin of a colony of resulting asteroids. It was originally the homeworld of the little-known Eellayin civilization, who dwelt in underground cities such as Wiyentaah, but the world was fractured by a mysterious cataclysm. This natural disaster formed a field of asteroids which remained known as Polis Massa, especially the largest of them. The Eellayin civilization disappeared.
