Centauri, a planet found in the Alpha Centauri System, is the chilly (-120°F, -84°C) homeworld of the Centauran species. Its temperature and anaerobic atmosphere make it uninhabitable to water-based life forms. The surface of Centauri is covered in city-sculptures such as the capital Shalyaris, which houses the international spaceport and the main office of the CRI. Foreigners are officially welcomed, but the complete lack of privacy afforded them tends to discourage emigration and tourism.
