Chyron is a moon orbiting the planet Perune. It has a Type I atmosphere capable of sustaining life, and is an ecumenopolis with its surface almost entirely covered by a city-sprawl. Frequent pockets of smog hang from pollution, causing acid rain to fall in the less developed sectors of the moon. It can best be described as a mini-Coruscant still under development, with all of the moon's natural lakes, seas, and rivers drained to make way for new development.
