Mimeosomes were built some time before the destruction of Earth with the technology provided by Elma, who felt that evacuating an actual population would prove too complex and time-consuming when the war between the Ganglion and the Ghost finally reaches Earth. For this reason, she instead proposed that the United States government upload the genetic material and memories of "skilled" people into a computer so they could be brought back through cloning after a planet had been settled by the White Whale. The people who were chosen to upload their memories and genetic material were led to believe that their bodies were to be put in stasis aboard the White Whale; however, this proved to be a lie by the government as the people chosen were left behind to die during the destruction of Earth.
