Dr. Conway must deal with an unconscious patient, classification ELPH, who may be a cannibal or a demigod, or both. It came from the "other galaxy", and the species is well known, almost infamous, to the Ians, who are also from another galaxy. It is extremely long-lived, and regularly takes complete rejuvenation treatments, including the brain and memory, to keep itself young. By doing this, it is practically immortal. It, although unconscious, appeared to have the ability to negate the most powerful drugs and resist surgery to cure its skin condition. This later turned out to be the work of the entity's "doctor", who is an intelligent, organized collection of microscopic, virus-type cells.
