The Xi'an Empire (SaoXy'an) is a multi-system government headed by the Xi'an Emperor and inhabited by the Xi'an. Its capital system, Hyoton, is the location of the former Xi'an homeworld RyiXy'an (Hyoton III) and Ka'ua (Hyoton IV), the current home of the Emperor. It is made up of thirteen known planetary systems. Political experts believe that there might be more systems that the Xi'an haven't divulged to other civilizations.
The Xi'an Empire borders the United Empire of Earth (UEE) along a series of planetary systems formerly known as the Perry Line. It also shares a border with Kr'thak territory, though the exact coordinates of this border are not known.
