With the acquisition of former CGD territory, Yamao space forces were sent to survey and establish control over these regions. Subsequently, the systems situated between the Yamao homeland and the former CGD were occupied. The construction of a reliable and safe supply lines to the new territories commenced, with stations and military bases developing on (the orbit of) various celestial bodies, gathering data from these regions to determine which locations will be most suitable for life. During this period prior to the occupation, although de jure a part of the Yamao Imperium, the CGD acted independently and carried out their own activities. Fortunately, their fragile government was already fractured by the CGD's war with CGD, allowing for the swift invasion and Yamao establishment of control over the region.
