Xanshi was a planetoid located in Space Sector 1313 with a diverse range of sentient life. One of its members, Reever, attracted the attention of the Guardians of the Universe who selected him to serve in the Green Lantern Corps. Reever defended the planet from a military expedition from Toomey VI but was ultimately defeated by Arkkis Chummuck, who was awarded a Green Lantern Power Ring due to his accomplishment and chose to maintaining peace between Xanshi and Toomey VI.
