These rooms are also referred to as WombSys. To populate the Domes, a central chamber in each Dome is dedicated to a ring of iron wombs, which appear to be feminine AutoReivs with grotesquely swollen abdominal regions that open into fleshy cavities. Humans are born from these domes, though it is suggested that the first generation (created either by humans, Proxies, or WombSys) was sterile. These figures appear to be held in suspended animation behind transparent partitions. It is stated that WombSys was necessary because it took longer to heal the planet than planned.
