Hyoton System

The Hyoton system is a planetary system in the Xi'an Empire (SaoXy'an) that consists of an F-type main sequence star, four terrestrial planets, and a super-Earth. The birthplace of the Xi'an people, it is the center of political power in the Xi'an Empire. Ka'ua (Hyoton IV), the present capital, is seat of the Emperor, and the jungle world Tethle'a (Hyoton II) is the home of some of its most powerful Houses. The former Xi'an capital and homeworld of the Xi'an, RyiXy'an (Hyoton III), was abandoned in the last days of the Great Divide when an assassination attempt perpetrated by House Kl.ō inadvertently set off a chain reaction that rendered the atmosphere toxic.
