Carteyna is the second planet from the star of the Cano system, United Empire of Earth (UEE). An ocean world discovered in 2463, Carteyna has resisted terraforming attempts. Its residents inhabit sealed arcologies surrounded by geothermal waters underneath the planet's northern ice cap. The Fair Chance Act was invoked to prevent further terraforming attempts when microscopic organisms exhibiting signs of intelligence were discovered in the ocean. While immigration is prohibited, the descendants of Carteyna's original settlers have been allowed to stay in Carteyna City.
