He had his doubts. He wondered if her human components, more than had gone into any other node, might not have given her emotions, intensified by ages of brooding, that skewed her rationality. However, he consented to her proposal. It accorded with his purpose in coming here.
While he was thus engaged, Christian would be exploring her worlds of history and of might-have-been and a different agent would range around the physical, present-day globe.
In the latter case, his most obvious procedure was to discharge an appropriate set of the molecular assemblers he had brought along and let them multiply. When their numbers were sufficient, they would build (grow; brew) a fleet of miniature robotic vessels, which would fly about and transmit to him, for study at his leisure, everything their sensors detected.
Gaia persuaded him otherwise: “If you go in person, with a minor aspect of me for a guide, you should get to know the planet more quickly and thoroughly. Much about it is unparalleled. It may help you see why I want the evolution to continue unmolested to its natural conclusion.”
He accepted. After all, a major part of his mission was to fathom her thinking. Then perhaps Alpha and the rest could hold a true dialogue and reach an agreement—whatever it was going to be. Besides, he could deploy his investigators later if this expedition left him dissatisfied.
He did inquire: “What are the hazards?”
“Chiefly weather,” she admitted. “With conditions growing more extreme, tremendous storms spring up practically without warning. Rapid erosion can change contours almost overnight, bringing landslides, flash floods, sudden emergence of tidal bores. I do not attempt to monitor in close detail. That volume of data would be more than I could handle”—yes, she—“when my main concern is the biological phenomena.”
His mind reviewed her most recent accounts to the stars. They were grim. The posthuman lushness of nature was megayears gone. Under its clouds, Earth roasted. The loftiest mountaintops were bleak, as here above the Rainbowl, but nothing of ice or snow remained except dim geological traces. Apart from the waters and a few islands where small, primitive species hung on, the tropics were sterile deserts. Dust and sand borne on furnace winds scoured their rockscapes. North and south they encroached, withering the steppes, parching the valleys, crawling up into the hills. Here and there survived a jungle or a swamp, lashed by torrential rains or wrapped hot and sullen in fog, but it would not be for much longer. Only in the high latitudes did a measure of benignity endure. Arctica’s climates ranged from Floridian—Christian Brannock’s recollections—to cold on the interior heights. South of it across a sea lay a broad continent whose northerly parts had temperatures reminiscent of central Africa. Those were the last regions where life kept any abundance.
“Would you really not care to see a restoration?” Wayfarer had asked her directly, early on.
“Old Earth lives in my database and emulations,” Gaia had responded. “I could not map this that is happening into those systems and let it play itself out, because I do not comprehend it well enough, nor can any finite mind. To divert the course of events would be to lose, forever, knowledge that I feel will prove to be of fundamental importance.”
Wayfarer had refrained from pointing out that life, reconquering a world once more hospitable to it, would not follow predictable paths either. He knew she would retort that experiments of that kind were being conducted on a number of formerly barren spheres, seeded with synthesized organisms. It had seemed strange to him that she appeared to lack any sentiment about the mother of humankind. Her being included the beings of many and many a one who had known sunrise dew beneath a bare foot, murmurs in forest shades, wind-waves in wheatfields from horizon to horizon, yes, and the lights and clangor of great cities. It was, at root, affection, more than any scientific or technological challenge, that had roused in Gaia’s fellows among the stars the wish to make Earth young again.
Now she meant to show him why she felt that death should have its way.
Before entering rapport with her, he made ready for his expedition. Gaia offered him an aircraft, swift, versatile, able to land on a square meter while disturbing scarcely a leaf. He supplied a passenger for it.
He had brought along several bodies of different types. The one he picked would have to operate independently of him, with a separate intelligence. Gaia could spare a minim of her attention to have telecommand of the flyer; he could spare none for his representative, if he was to range through the history of the globe with her.
The machine he picked was not equivalent to him. Its structure could never have supported a matrix big enough to operate at his level of mentality. Think of it, metaphorically, as possessing a brain equal to that of a high-order human. Into this brain had been copied as much of Wayfarer’s self-pattern as it could hold—the merest sketch, a general idea of the situation, incomplete and distorted like this myth of ours. However, it had reserves it could call upon. Inevitably, because of being most suitable for these circumstances, the Christian Brannock aspect dominated.
So you may, if you like, think of the man as being reborn in a body of metal, silicates, carbon and other compounds, electricity and other forces, photon and particle exchanges, quantum currents. Naturally, this affected not just his appearance and abilities, but his inner life. He was not passionless, far from it, but his passions were not identical with those of flesh. In most respects, he differed more from the long-dead mortal than did the re-creation in Gaia’s emulated worlds. If we call the latter Christian, we can refer to the former as Brannock.
His frame was of approximately human size and shape. Matte blue-gray, it had four arms. He could reshape the hands of the lower pair as desired, to be a tool kit. He could similarly adapt his feet according to the demands upon them, and could extrude a spindly third leg for support or extra grip. His back swelled outward to hold a nuclear energy source and various organs. His head was a domed cylinder. The sensors in it and throughout the rest of him were not conspicuous but gave him full-surround information. The face was a holographic screen in which he could generate whatever image he wished. Likewise could he produce every frequency of sound, plus visible light, infrared, and microwave radio, for sensing or for short-range communication. A memory unit, out of which he could quickly summon any data, was equivalent to a large ancient library.
He could not process those data, comprehend and reason about them, at higher speed than a human genius. He had other limitations as well. But then, he was never intended to function independently of equipment.
He was soon ready to depart. Imagine him saying to Wayfarer, with a phantom grin, “Adiós. Wish me luck.”
The response was … absentminded. Wayfarer was beginning to engage with Gaia.
Thus Brannock boarded the aircraft in a kind of silence. To the eye it rested small, lanceolate, iridescently aquiver. The material component was a tissue of wisps. Most of that slight mass was devoted to generating forces and maintaining capabilities, which Gaia had not listed for him. Yet it would take a wind of uncommon violence to endanger this machine, and most likely it could outrun the menace.
He settled down inside. Wayfarer had insisted on manual controls, against emergencies that he conceded were improbable, and Gaia’s effectors had made the modifications. An insubstantial configuration shimmered before Brannock, instruments to read, keypoints to touch or think at. He leaned back into a containing field and let her pilot. Noiselessly, the flyer ascended, then came down through the cloud deck and made a leisurely way at five hundred meters above the foothills.
“Follow the Remnant River to the sea,” Brannock requested. “The view inbound was. beautiful.”
“As you like,” said Gaia. They employed sonics, his voice masculine, hers—perhaps because she supposed he preferred it—feminine in a low register. Their conversation did not actually go as reported here. She changed course and he beheld the stream shining amidst the deep greens of the Bountiful Valley, under a silver-gray heaven. “The plan, you know, is that we s
hall cruise about Arctica first. I have an itinerary that should provide you a representative sampling of its biology. At our stops, you can investigate as intensively as you care to, and if you want to stop anyplace else we can do that too.”
“Thank you,” he said. “The idea is to furnish me a kind of baseline, right?”
“Yes, because conditions here are the easiest for life. When you are ready, we will proceed south, across countries increasingly harsh. You will learn about the adaptations life has made. Many are extraordinarily interesting. The galactic brain itself cannot match the creativity of nature.”
“Well, sure. Chaos, complexity … You’ve described quite a few of those adaptations to, uh, us, haven’t you?”
“Yes, but by no means all. I keep discovering new ones. Life keeps evolving.”
As environments worsened, Brannock thought. And nonetheless, species after species went extinct. He got a sense of a rear-guard battle against the armies of hell.
“I want you to experience this as fully as you are able,” Gaia said, “immerse yourself, feel the sublimity of it.”
The tragedy, he thought. But tragedy was art, maybe the highest art that humankind ever achieved. And more of the human soul might well linger in Gaia than in any of her fellow intelligences.
Had she kept a need for catharsis, for pity and terror? What really went on in her emulations?
Well, Christian was supposed to find out something about that. If he could.
Brannock was human enough himself to protest. He gestured at the land below, where the river flowed in its canyons through the coastal hills, to water a wealth of forest and meadow before emptying into a bay above which soared thousands of wings. “You want to watch the struggle till the end,” he said. “Life wants to live. What right have you to set your wish against that?”
“The right of awareness,” she declared. “Only to a being that is conscious do justice, mercy, desire have any existence, any meaning. Did not humans always use the world as they saw fit? When nature finally got protection, that was because humans so chose. I speak for the knowledge and insight that we can gain.”
The question flickered uneasily in him: What about her private emotional needs?
Abruptly the aircraft veered. The turn pushed Brannock hard into the force field upholding him. He heard air crack and scream. The bay fell aft with mounting speed.
The spaceman in him, who had lived through meteoroid strikes and radiation bursts because he was quick, had already acted. Through the optical magnification he immediately ordered up, he looked back to see what the trouble was. The glimpse he got, before the sight went under the horizon, made him cry, “Yonder!”
“What?” Gaia replied as she hurtled onward.
“That back there. Why are you running from it?”
“What do you mean? There is nothing important.”
“The devil there isn’t. I’ve a notion you saw it more clearly than I did.”
Gaia slowed the headlong flight until she well-nigh hovered above the strand and wild surf. He felt a sharp suspicion that she did it in order to dissipate the impression of urgency, make him more receptive to whatever she intended to claim.
“Very well,” she said after a moment. “I spied a certain object. What do you think you saw?”
He decided not to answer straightforwardly—at least, not before she convinced him of her good faith. The more information she had, the more readily she could contrive a deception. Even this fragment of her intellect was superior to his. Yet he had his own measure of wits, and an ingrained stubbornness.
“I’m not sure, except that it didn’t seem dangerous. Suppose you tell me what it is and why you turned tail from it.”
Did she sigh? “At this stage of your knowledge, you would not understand. Rather, you would be bound to misunderstand. That is why I retreated.”
A human would have tensed every muscle. Brannock’s systems went on full standby. “I’ll be the judge of my brain’s range, if you please. Kindly go back.”
“No. I promise I will explain later, when you have seen enough more.”
Seen enough illusions? She might well have many trickeries waiting for him. “As you like,” Brannock said. “Meanwhile, I’ll give Wayfarer a call and let him know.” Alpha’s emissary kept a minute part of his sensibility open to outside stimuli.
“No, do not,” Gaia said. “It would distract him unnecessarily.”
“He will decide that,” Brannock told her.
Strife exploded.
Almost, Gaia won. Had her entirety been focused on attack, she would have carried it off with such swiftness that Brannock would never have known he was bestormed. But a fraction of her was dealing, as always, with her observing units around the globe and their torrents of data. Possibly it also glanced from time to time—through the quantum shifts inside her—at the doings of Christian and Laurinda. By far the most of her was occupied in her interaction with Wayfarer. This she could not set aside without rousing instant suspicion. Rather, she must make a supremely clever effort to conceal from him that anything untoward was going on.
Moreover, she had never encountered a being like Brannock, human male aggressiveness and human spacefarer’s reflexes blent with sophisticated technology and something of Alpha’s immortal purpose.
He felt the support field strengthen and tighten to hold him immobile. He felt a tide like delirium rush into his mind. A man would have thought it was a knockout anesthetic. Brannock did not stop to wonder. He reacted directly, even as she struck. Machine fast and tiger ferocious, he put her off balance for a crucial millisecond.
Through the darkness and roaring in his head, he lashed out physically. His hands tore through the light-play of control nexuses before him. They were not meant to withstand an assault. He could not seize command, but he could, blindly, disrupt.
Arcs leaped blue-white. Luminances flared and died. Power output continued; the aircraft stayed aloft. Its more complex functions were in ruin. Their dance of atoms, energies, and waves went uselessly random.
The bonds that had been closing on Brannock let go. He sagged to the floor. The night in his head receded. It left him shaken, his senses awhirl. Into the sudden anarchy of everything he yelled, “Stop, you bitch!”
“I will,” Gaia said.
Afterward he realized that she had kept a vestige of governance over the flyer. Before he could wrest it from her, she sent them plunging downward and cut off the main generator. Every force field blinked out. Wind ripped the material frame asunder. Its pieces crashed in the surf. Combers tumbled them about, cast a few on the beach, gave the rest to the undertow.
As the craft fell, distintegrating, Brannock gathered his strength and leaped. The thrust of his legs cast him outward, through a long arc that ended in deeper water. It fountained high and white when he struck. He went down into green depths while the currents swept him to and fro. But he hit the sandy bottom unharmed.
Having no need to breathe, he stayed under. To recover from the shock took him less than a second. To make his assessment took minutes, there in the swirling surges.
Gaia had tried to take him over. A force field had begun to damp the processes in his brain and impose its own patterns. He had quenched it barely in time.
She would scarcely have required a capability of that kind in the past. Therefore she had invented and installed it specifically for him. This strongly suggested she had meant to use it at some point of their journey. When he saw a thing she had not known was there and refused to be fobbed off, he compelled her to make the attempt before she was ready. When it failed, she spent her last resources to destroy him.
She would go that far, that desperately, to keep a secret that tremendous from the stars.
He recognized a mistake in his thinking. She had not used up everything at her beck. On the contrary, she had a planetful of observers and other instrumentalities to call upon. Certain of them must be bound here at top speed, to make sure he was dead—or, if h
e lived, to make sure of him. Afterward she would feed Wayfarer a story that ended with a regrettable accident away off over an ocean.
Heavier than water, Brannock strode down a sloping sea floor in search of depth.
Having found a jumble of volcanic rock, he crawled into a lava tube, lay fetally curled, and willed his systems to operate as low-level as might be. He hoped that then her agents would miss him. Neither their numbers nor their sensitivities were infinite. It would be reasonable for Gaia—who could not have witnessed his escape, her sensors in the aircraft being obliterated as it came apart—to conclude that the flows had taken his scattered remains away.
* * *
After three days and nights, the internal clock he had set brought him back awake.
He knew he must stay careful. However, unless she kept a closer watch on the site than he expected she would—for Wayfarer, in communion with her, might too readily notice that she was concentrating on one little patch of the planet—he dared now move about. His electronic senses ought to warn him of any robot that came into his vicinity, even if it was too small for eyes to see. Whether he could then do anything about it was a separate question.
First he searched the immediate area. Gaia’s machines had removed those shards of the wreck that they found, but most were strewn over the bottom, and she had evidently not thought it worthwhile, or safe, to have them sought out. Nearly all of what he came upon was in fact scrap. A few units were intact. The one that interested him had the physical form of a small metal sphere. He tracked it down by magnetic induction. Having taken it to a place ashore, hidden by trees from the sky, he studied it. With his tool-hands he traced the (mythic) circuitry within and identified it as a memory bank. The encoding was familiar to his Wayfarer aspect. He extracted the information and stored it in his own database.
A set of languages. Human languages, although none he had ever heard of. Yes, very interesting.
“I’d better get hold of those people,” he muttered. In the solitude of wind, sea, and wilderness, he had relapsed into an ancient habit of occasionally thinking aloud. “Won’t likely be another chance. Quite a piece of news for Wayfarer.” If he came back, or at least got within range of his transmitter.
