M.iiy'ong (Ail'ka IV) is the fourth planet from the sun in the Ail'ka system, Xi'an Empire (SaoXy'an). As a base of operations for the Xi'an military, M.iiy'ong is a densely populated, busy world that houses flight academies, command centers, intelligence facilities, and barracks, among other military-related locations. Many transportation, armor, and weapons manufacturers operate from M.iiy'ong, including military spacecraft company Aopoa. While non-Xi'an are allowed to visit, travel is still highly restricted.
