“Thank you, friend Murchison,” Prilicla said, “but no.”
“But yes, Senior Physician,” the Pathologist replied. “With respect, you have the rank but not the muscles stop me.”
Impatiently Cha Thrat said, “if you want to be able to detect any conscious emotional radiation, please hurry. The patient needs urgent attention …”
There was an immediate objection from Fletcher regarding her unjustified use of the word “patient.” She ignored it and, trying her best to describe the thoughts and images that had been placed with so much effort in her mind, went on to outline the case history of the survivor and the history of its species.
They came from a world that even the Sommaradvan, Gogleskan, and Earth-human components of her mind considered beautiful, a planet so bountiful that the larger species of fauna did not have to struggle for survival and did not, for that reason, develop intelligence. But from the earliest times, when all life was in the oceans, a species evolved capable of attaching itself to a variety of native life-forms. They formed a symbiotic partnership in which the host creature was directed to the best sources of food while the weak and relatively tiny parasite had the protection of its larger mount as well as the mobility that enabled it to seek out its own, less readily available food supply. By the time the host creatures left the oceans to become large and unintelligent land animals, the mutually profitable arrangement continued and the parasite had become very intelligent indeed.
The earliest recorded history told of vain attempts to nurture intelligence in many different species of host creature. The native, six-limbed FGHJ life-form with its ability to work in a wide variety of materials, when aparasite was directing its hands, was favored above all the others.
But more and more they had wished for mind-partners they could not control, beings who would argue and debate and contribute new ideas and viewpoints, rather than creatures who were little more than general-purpose, self-replenishing organic tools with the ability to see, hear, and manipulate to order.
With these tools they built great cities and manufacturing complexes and vessels that circumnavigated their world, flew in the atmosphere above it, and, ultimately crossed the terrible and wonderful emptiness between the stars. But the cities, like their starships, were functional and unbeautiful because they had been built by and for the comfort and use of beings without any appreciation of beauty, and whose animal needs were satisfied by food, warmth, and regular satisfaction of the urge to procreate. Like valuable tools they had to be properly maintained, and many of them were well loved with the affection that a civilized being feels for a faithful but nonintelligent pet.
But the parasites had their own special needs that in no respect resembled those of their hosts, whose animal habits and undirected behavior were highly repugnant to them. It was vital to their continued mental well-being that the masters escaped periodically from their hosts to lead their own lives — usually during the hours of darkness when the tools were no longer in use and could be quartered where they could not harm themselves. This they did in the small, quiet, private places, tiny areas of civilization and culture and beauty amid the ugliness of the cities, where their families nested and they were separated from the host creatures by everything but distance.
It had long been an accepted fact among them that nc creature or culture could avoid stagnation if it did not; outside its family or its tribe or, ultimately, its world. Ir their continuing search for other intelligent beings like or totally unlike themselves, many extrasolar planets had been discovered and small colonies established on them, but none of the indigenous life-forms possessed intelligence and had become just so many sets of other-species tools.
Because of an intense aversion to allowing themselves to be touched by the proxy hands of a nonintelligent creature, their medical science catered chiefly to the needs of their hosts and did not include surgery. The result was that when one of their own-planet tools contracted a disease that, to it, was mildlydebilitating, the effect on the parasite was often lethal.
Cha Thrat paused for a moment and raised one of her upper hands to support the weight of the parasite. Sensation had returned to her neck and she felt that the creature’s tendrils were loosening and pulling free. She could hear Prilicla and Murchison on the deck below.
“That is what happened to their ship,” she went on. “The host FGHJs caught something that caused a mild, undulant fever, and recovered. The parasites, with this one exception, perished. But before they returned to their own quarters to die, they placed their now-undirected host creatures in places where food was available and they would not injure themselves, in the hope that help would reach the host creatures in time. The survivor, who seemed to have a partial resistance to the disease, rendered the vessel safe and accessible to rescuers, released the distress beacon, and returned to the ship’s Nest to comfort its dying friends.
“But the effort to do this work,” Cha Thrat went on, talking directly to Prilicla and Murchison who were nowcoming up the ramp toward her, “was too much for its host, an aging FGHJ of whom it was particularly fond, and the creature had a sudden cardiac malfunction and died inside the Nest,"The distress signal was answered not by one of their own ships, but by Rhabwar” she concluded, “and the rest we know.”
Prilicla did not reply and Murchison moved to one side, keeping the thin tube of its cutting torch aimed at the back of Cha Thrat’s neck. Nervously the Pathologist said, “I’d need to check it with my scanner, of course, but I’d say physiological classification DTRC. It’s very similar to the DTSB symbiotes some FGLIs wear for fine surgical work. In those cases it’s the parasite who supplies the digits and the Tralthan the brains, although there are some OR nurses who would argue about that …”
It broke off as Cha Thrat said, “I have been trying to relinquish control of my speech centers so that it would be able to talk to you directly through me, but it is much too weak and is only barely conscious, so I must be its voice. It already knows from my mind who you are, and it is Crelyarrel, of the third division of Trennchi, of the one hundred and seventh division of Yau, and of the four hundred and eighth subdivision of the great Villa of the Rhiim. I cannot properly describe its feelings in words, but there is joy at the knowledge that the Rhiim are not the only intelligent species in the Galaxy, sorrow that this wonderful knowledge will die with it, and apologies for anxiety it caused us by—”
“I know what it is feeling,” Prilicla said gently, and suddenly they were washed by a great, impalpable wave of sympathy, friendship, and reassurance. “We are happy to meet you and learn of your people, friend Crel-yarrel, and we will not allow you to die. Let go now, little friend, and rest, you are in good hands.”
Still radiating its emotional support, it went on briskly. “Put away that cutting torch, friend Murchison, and go with the patient and friend Cha to the Rhiim quarters. It will feel more comfortable there, and you have much work to do on its dead friends. Friend Fletcher, preparations will have to be made at the hospital to receive this new life-form. Be ready to send a long hypersignal to Thornnastor as soon as we have a clearer idea of the clinical picture. Friend Naydrad, stand by with the litter in case we need special equipment here, or for the transport of DTRC cadavers to Rhabwar for investigation—”
