|Location||Orbiting Oya (star)|
Before the Perry Line was formed, Oya III was in the process of being colonized by the Xi'an and was home to a settlement. The inhabitants were displaced back into Xi'an territory when tensions began to rise. Even though the planet is under UEE control, the former Xi'an settlement was given back to the Xi'an Empire as an act of good faith, making it the only slice of sovereign alien territory within the Empire.
