UX-10 sits near the space lane connecting central and Southern Yamatai. It has one habitable planet, UX-10 I.

In YE 35, the Yamatai Star Empire laid claim to this star system. The Yamatai Star Empire placed orbital communications networks of Emrys Satellites around all of the terrestrial planets in YE 36.

In YE 41, the UX-10 star system was conquered by forces from the Interstellar Kingdom Of Kuvexia during the Kuvexian Invasion of YE 41.
