Kōri'lya is a major city on Xi (R.il'a V), Xi'an Empire (SaoXy'an). Originally filled with barracks for soldiers and support staff that worked and trained on neighboring planet Xōl'uu (R.il'a IV), the city was reclassified as a residential zone by the Xi'an government after the end of the Xi'an-Human Cold War (SEY 2530 - 2793 / MXY III.838 - III.1044). It was additionally opened to non-Xi'an, and has become a center of cultural exchange where Banu, Human, and Tevarin intermingle with the Xi'an populace. Surrounded by dense tropical rainforests, it is lushly vegetated and stays warm throughout the year.
