Kaiki is an unclassified world in the Rubycon II System located between the Calixis Sector and the Koronus Passage that leads to the Expanse. Along with its twins Apeli and Skiri, Kaiki is a small planet of frozen gas and ice. The three worlds slowly travel along highly elliptical orbital paths that take hundreds of years. These orbits carry them far beyond Ruby’s light and into the system’s Ort Cloud. The Adeptus Mechanicus have built a station upon Skiri and several expeditions have been mounted to chart and explore Kaiki and Apeli. Cursory examinations revealed nothing of interest, yet legends and myths abound in the port about buried treasures and secret xenos cities below the planets’ icy exteriors.
