Hexie (say: hey-shay) is a planet in a chi-based universe. It is home to nine intelligent species. For decades, it was subject to two bloody wars that resulted in its being partitioned into five planets.
Originally, there were six intelligent species occupying the planet: the Bennu, the No Kuha, the Kragan, the Popa, the Mahtla, and the Avarav. They originally lived separate from each other. However, they were eventually brought together by the coming of the Great Snake. Her arrival, plus the Ryuu and the Dagze (newly morphed into the Chi Lin) brought the count of intelligent species up to nine.
During the first Angel War, nine more species were brought to the planet of Mu Hexie from a similarly chi-based world called Askr.
