The scientists then decide to wake up the man, Coban, who could personally deliver the knowledge they seek. He would require a blood transfusion, but Eléa, the only living donor for his blood type, poisons herself to kill the man she hates and then die. She had, however, been replaying her actual memories of her last days prior to the freeze, to the scientists, and she was not aware that just as she was put under anesthesia for the freeze process, her mind was recording events around her that she was not conscious of, and at the last minute, her lover had confronted the scientist Coban, killed him, and taken his place. The man she had just poisoned with her dying blood was in fact her lover, for she had not seen the body for the whole of the book, and no one could have known the body was his. she dies before the scientists could tell her her tragic mistake, at the same moment her lover dies. All recordings and engravings of the advanced knowledge are either destroyed or now completely uninterpretable, and mankind loses this knowledge again.
