Xyekyu (Ē'aluth IV) is the fourth planet from the sun of the Ē'aluth system, Xi'an Empire (SaoXy'an). A gas dwarf, its swirling blue and white atmosphere hides a rocky core and an icy ocean of ammonia and water. The platforms that serve as housing for the scientists, managers, and protectors of the nature preserve on the nearby planet Ko'li (Ē'aluth III) are mostly located in orbit around Xyekyu.
