in her lower abdomen carries the gene that can save the city if it is taken to its very edge where it can grow uncontaminated by the megastructure and its inhabitants. Sanakan mentions that the "child" is a product of hers and Cibo's combined DNA. Cibo is heavily weakened by Killy's GBE shortly after her transformation, reverting to a childlike state and eventually falling into the hands of the Silicon Creatures despite Sanakan's efforts to find and protect her. Sanakan asks for a return to the Base Reality without backup data, driven by a desire to protect her "child"and charge.
