The Mind Pool

Chapter 22

Dear Chan,

This is a letter that I never expected to write, a message I never dreamed I would send, especially (don’t misunderstand this) to you. But it’s our first night down on Travancore, and I’m flat out scared. Tonight I wish you and I were still down in the Gallimaufries, watching Bozzie preach self-denial while he gobbled down a dozen waffles with honey.

If we can’t be together, at least let me babble at you for a while. We — the team, I mean, they gave us a rotten name, Team Alpha, but I hope we’ll come up with something better for ourselves — anyway, my team, Team Alpha or whatever, we weren’t allowed to bring a Martin Link ship anywhere near Travancore. No matter what happens here, Commander Mondrian won’t risk the Morgan Construct having access to a Link again. So this message will be fired off to the ship, a million kilometers away, then through a Link back to Sol, then through the Censor’s office, and then, if everything works out right, you’ll get it before you leave Barchan. Good luck down there. The last word I had, you have the hottest Pursuit Team they’ve seen since training began. I hope so — and I hope you will never have to visit Travancore. Because if you do, it will mean that we have failed.

I said that we are “down on Travancore” but that’s more like a figure of speech than anything else. We don’t know where the true surface of the planet begins. No one does. We’re hanging in a sort of half-balloon tent with a flat, flexible base, about a hundred feet down from the topmost growths of vegetation. There’s another five-kilometers-plus of plant life underneath us.

Animal life, too. We saw the first signs of that on the low-altitude automated survey. The whole planet is riddled with holes, circular shafts about five meters across. They dive down from the top layers, and at first we thought they might be natural rain channels because it rains every day over most of Travancore. But now we’re not so sure. S’glya — she’s the Pipe-Rilla on our team — saw something Dig wriggling away down one of the tunnels when we were flying in. Scary. But I was mainly happy that it wasn’t the Morgan Construct, because we were a sitting target. I tried to hide my panicky feeling but of course it didn’t work. S’glya has this absolutely uncanny ability to read human feelings and she told the others.

They didn’t seem worried. It’s an unpleasant thought for me, the idea that soon we’ll be heading down one of those tunnels, but the Tinker feels quite different about that. It argues that the tunnels are a big boon to us, since without them it would take forever to explore the vertical forest on Travancore. Maybe it will take forever anyway. We’ll know, as soon as we get down to the interior.

Even before we made the final descent we decided that the training program had missed the point. We were sent to Dembricot for final training, because it’s a vegetation world like Travancore and everyone thought it would be good experience for this place.

Logical idea, but totally wrong. You must have seen the training films of Dembricot by now. Flat, water plains of plant growth, but they’re no more like Travancore than Barchan is. This planet is dense, tangled hillocks of jungle, boiling up in swirls and breakers like one of Earth’s seas in a bad storm.

One good thing: I can breathe the air with just a compressor. I should be able to manage without even that when we get down to a lower level where the pressure is higher. We’re all doing well. S’glya needs a heating unit, and Angel had to do some mysterious interior modification before the atmosphere was acceptable, but that’s all.

The view from the top layer of vegetation is spectacular at the moment. Travancore’s primary, Talitha, is close to setting, and when it’s low on the horizon it shines through mile after mile of ferns and leaves and vines. No flowers, I’m afraid — Travancore wouldn’t please old Bozzie. Everything in sight is greener than green, except for the Top Creepers. That’s not their official biological name, but it’s a good description. They are purple, gigantic lateral creepers that snake away across the top of everything as far as you can see. And I mean gigantic. They’re only a few meters across, but each one is many kilometers long. In spite of their size they are not at all dense and heavy. I tried to take a sample from one, because I couldn’t see how the rest of the vegetation could possibly support that much weight.

When I cut into it there was a hissing sound and a horrible smell, and the level of the vegetation around the Top Creeper went down a fraction. The whole thing has to be nothing more than a wafer-thin shell stretched out over a hollow center full of light gases. Now I suspect that they are actually holding the other plants up.

I told you I was going to babble, and I think I’m doing it, but I hope that I’m justified. If you do have to come here, the more you know about the place ahead of time, the better. We were trained as well as we could be, but it surely wasn’t enough. No one has ever looked closely at Travancore before. With no defined surface and no open water, no one thought that it was worth it. We have more questions than answers.

More about those mysterious holes. They keep preying on my mind. Angel’s imaging organs (can’t call them eyes) can be tuned to the thermal infra-red. Angel took a heat-wavelength look down one of the shafts, and claims that it isn’t vertical at all. It spirals down in a helix, which rules out the natural rain-channel idea. We’ll soon have a better explanation, I expect, because we’ll be going down one. I hope that I’m around after that, to send you a description. Anyway, whatever happens to us our ship ought to be receiving a full record of it.

And more about Travancore, too. Naturally we’ve thought about nothing else since we got here. There are plenty of mysteries not even mentioned in the briefing documents. For example: gravity and air. The surface gravity is only a little more than a quarter of Earth’s. So now can it hold onto a substantial atmosphere, and support this massive cover of vegetation? The air should have bled away into space long ago.

Well, according to S’glya, Travancore has its atmosphere because of the strange vegetation layer. The canopy of plant life is so dense and continuous that it can trap air molecules within and beneath it. We know there is something close to a pressure discontinuity up near the top here.

And of course it’s a chicken-and-egg situation because the atmosphere is absolutely necessary for the vegetation to exist! The plant cover must have developed very early in Travancore’s history. And if S’glya is right, the shafts we saw can’t go down uninterrupted all the way to the solid surface, because otherwise they could act as escape vents for the air. So we may have to cut our way through barriers, one more little difficulty. But just to add to the confusion, Angel says that S’glya’s idea about the relationship of the atmosphere and the vegetation is wrong — for six reasons still to be specified.

Well, what’s the good news? The team is the good news. We’re an odd assortment. We have a Tinker whose real name sounds like a breaking window, but who asks me to call it Ishmael. Its big ambition in life seems to be to snuggle up to the rest of us. Then there’s Angel, who won’t stop using human proverbs and clichйs, and who insists that Angels don’t have names. And last of all there’s S’glya, who seems to know what I’m thinking and feeling without being told. S’glya’s not her real Pipe-Rilla name, either, because that’s unpronounceable too.

Weird. But it all works! Once we got to know each other we’ve been achieving an unbelievable level of communication and cooperation. It seems as though anything that one of us can’t do, another one can. We first noticed it back on Barchan, and it has just gone on getting better and better.

Better and better — but God only knows if it will be good enough. Angel says that the Morgan Construct is a superior being, beyond even Angel.

Full night here now. Time to sleep.

Keep your fingers crossed for me, Chan, wherever you are. I love you, and I’ve always loved you since you were a baby. I can’t forgive myself for running away and refusing to speak to you when you were on Ceres with Tatty. But it was awfully hard for me to admit that I don’t own you any more.

I hope that you can forgive me. And I hope that some day I can make up for what I did then.

Yours, Leah.

Chan had read it through again and again. After the third time he could have repeated it word for word.

He kept going back to the last few paragraphs. Leah’s words of love bowled him over — and her remarks about the level of communication between her team members baffled him completely. Over the past couple of days he had become convinced that his own team would never work well together. They had too much trouble understanding each other. Well, maybe Shikari, as the Tinker liked to be called, would be all right. Shikari sometimes made perfect sense. So did the Pipe-Rilla, now and again, although neither she nor the Tinker seemed to have the equivalent of facial expressions. If they had some kind of body language for use with their own species, he had no idea how to read it.

As for the Angel, that was mystery personified. The creature had no face, no mouth, no method of communication except through a computer interface. And even that output was often incomprehensible, though Shikari and the Pipe-Rilla understood it (or pretended to).

And this mismatched assembly was supposed to be able to track down and destroy the most dangerous being in the known universe! They would be lucky if the Artefact simulation of the Construct, here on Barchan, didn’t tie them in knots.

They had established their camp down near the planet’s south pole. Until they knew the Simmie Artefact’s location there was no point in enduring the dreadful summer heat of the equator and northern hemisphere. On this third evening, as the dark sands of Barchan gradually cooled, the Pursuit Team settled down to its first strategy session.

The Tinker had increased noticeably in size as the sun set and the air was less scorchingly hot. The central mass contained almost twice as many components as when Chan had first met it, and its response time was painfully slow. The other three waited (impatiently, in at least Chan’s case) while Shikari’s speech funnel made its preparatory wheezes and whistles.

The Pipe-Rilla, S’greela, was crouched next to Chan and nervously stroking her multi-jointed forelimbs along the side of her head. If her performance to date was any guide, when confronted by anything the least frightening she would chitter in horror and terror and run away with great spring-legged leaps.

The Angel at least would not run away. It could not. No matter how intelligent the crystalline Singer might be, it was bound within the vegetable body of the Chassel-Rose and suffered that plant’s extreme slowness of movement. When the Angel wanted to move, the bulbous green body first lifted the root-borers up close underneath it. When they were stowed safely away it could creep along on the down-pointing adventitious stems at the edge of the body base. Chan guessed that if it was in a real hurry it might manage up to a hundred steps an hour.

Which left only the Tinker, Shikari, as a possibly useful ally. But its reaction to danger had already been demonstrated. It at once dispersed to individual components, and they flew away.

The curious thing was that the other three did not share Chan’s worries at all.

“We think that we have a satisfactory approach.” Shikari was finally speaking, slow and ponderous. “The Simulated Artefact lacks circadian rhythms and is indifferent to night or day. But our team is not. We Tinkers prefer to cluster by night, and Chan needs to become dormant. However, S’greela is naturally nocturnal, and like the Chassel-Rose she has excellent night vision. This, therefore, is our suggestion. Angel and S’greela should perform a night survey, seeking the Simmie. Human and self will remain here and rest. If there is no success in the search, then when daylight comes we will reverse the roles.”

The long blue-green fronds at the top of the Angel began to wave slowly in the air. Chan, ready to speak, paused. He had seen that motion before, when the Angel’s computer communicator was beginning its translation. Maybe even an Angel had some kind of body language.

“We agree,” said the translator’s mechanical voice. “However, we propose one difference. We believe that we now know the probable location of the Simulated Artefact. Therefore, the mission for Angel and Pipe-Rilla should be one of confirmation, not of search.”

“But how can you? — ” Chan stopped. The ferny fronds were still waving.

“We have completed the analysis of imaging radar records obtained during orbital survey,” went on the Angel. “There are two significant anomalies. One of them is our base. The other is almost certainly the Simulacrum. We request a brief pause, while we perform a confirming analysis. We have stored a copy of the ship’s data record.”

The Angel had answered Chan’s half-spoken question, plus another one about the ship’s records that he had thought but not even started to ask.

Telepathy? Even as the thought came, Chan rejected it. He remembered what Flammarion had told him during a Ceres briefing: “An Angel doesn’t normally think like a human, but not because it can’t. When an Angel wants to, it can put part of its brain into what we call ‘emulator mode.’ Then that piece can be instructed by the Angel to think like a human, or a Pipe-Rilla, or a Tinker of any number of components, or maybe like all three at once. And probably any other creature you care to name, maybe even like a Morgan Construct. And while all that’s going on, the Angel still performs logical analysis in its own way. Whatever that might be.” At that point Kubo Flammarion had seemed puzzled by his own words, and rugged at his uniform as though it had become too small for him.

During Chan’s moment of recollection, the Pipe-Rilla S’greela had unfolded its long, telescoping limbs and was reaching down to pick up the Angel. The Angel had objected to this the first time, protesting that it was quite capable of independent locomotion. But after two minutes of watching the Chassel-Rose’s lumbering progress, the other three had been unanimous. In any travel involving them, Angel would be carried.

Chan watched S’greela now as she easily picked up Angel’s pear-shaped bulk. More and more he was aware of the power in the thin, pipe-stem body. S’greela was gentle, but if she ever chose not to be she could swat Chan like a troublesome insect.

Shikari remained a few feet away from Chan. The Tinker did not speak as S’greela and Angel left in the air-car. It occurred to Chan that he was observing another data point. The others were very economical of words unless he became involved in the conversation; then human-style verbal padding was added for his benefit. They had realized that redundant words were part of human social interaction, as important to Chan as stroking to a Pipe-Rilla or clustering to a Tinker.

Chan stood up and moved across to sit by Shikari. After a few moments he felt the feathery touch of long, delicate antennae on his arms and legs. The Tinker Composite was quietly performing a partial disassembly and rebuilding. Thumb-sized components were leaving the far side of the great clump and re-attaching themselves close to Chan’s body. Within five minutes Shikari was molded solidly against Chan’s left side, touching him all the way from breast to ankles.

He turned his head and stared down at the purple-black vibrating mass. The contact was not at all unpleasant. In fact, that gentle thrumming touch against his skin began to feel surprisingly warm and reassuring. After a few more moments, free components who had not been part of the Tinker Composite when Chan sat down flew across and made additional connections. Soon Chan’s whole body, from feet to shoulders, was embedded in the largest purple swarm he had ever encountered.

He felt very relaxed now, but not sleepy. The pressure around him was just enough to be noticed. But the pilot’s words drifted back to Chan. If a Tinker chose to swarm on something as a means of restraint, it could be formidable. Shikari had its own way of neutralizing aggression.

He watched as a final few components flew in to attach themselves. “Do you feel different, when more units attach?”

There was an experimental whistle from the speaking funnel. “Of course.’

After a long silence, Chan realized that the Tinker had given its full answer. “I don’t mean more intelligent. I know that’s true. What I mean is, do you feel that you are a different individual when your size is increased so much?”

The Tinker was silent for an even longer period. “That is a difficult question.” Even its voice was slower and deeper in pitch. “We are also not sure that it is a meaningful one. We are what we are, at the moment. We cannot feel what we were or will be. We will answer your question with a question. Every second, according to information that we have received concerning humans, some of your brain cells die. Do you feel different when those units of intellect are removed from you?”

“It’s not the same. In the case of a human, every brain cell has been there since childhood. We do not add units.” (And brain cells are only a part of the story — should I tell Shikari how recently I achieved real use of my brain?) “We lose cells slowly. But to change, recombine, and add or subtract units, constantly and quickly, as you do … it is hard for me to comprehend how you retain the sense of a single identity during a time of major change.”

The Tinker rippled suddenly against Chan’s body. A cascade of about five hundred units flew away to settle on the ground as individual components.

“Like that, you mean?” There was a breathy rattle from the voice funnel, as though the Tinker was practicing a human laugh. “There is more than enough capacity for continuous thought, even when no more than five hundred components are present. Remember, each of the units that form us possesses nearly two million neurons.”

“That sounds like very few.”

“Few compared with a human, or a complete Composite. But compare one of our components with one of your honeybees. It has no more than seven thousand neurons, and yet it is capable of complex individual actions.”

There was another whir of tiny wings as the units came flying back to rejoin the mass around Chan’s body. The voice funnel wheezed, in a more successful attempt at a human sigh.

“We have far to go,” said Shikari, “before we can really understand each other. When first we encountered humans we marvelled at your strange structure. How could intelligence be delegated, to reside in some special chosen group of cells within your body? Within us, each component carries an equal amount of our intelligence. But now much of your thinking power lies here” — Chan felt a gentle pressure on his midriff — “or here.” The touch moved to the calf of his left leg. “What intelligence lies in these parts? What are the thoughts of an arm, or a lung? You will say, none. We cannot comprehend that. Yet we know it is true that a human can be reduced to less than half its size, lacking arms and legs, and have its intelligence continue unchanged!”

“Less than that. There have been successful human brain transplants, and no lessening of thinking ability.”

“Who would believe such a thing, if we had not encountered it? — If humans had not arrived on Mercantor, and proved it to us.” There was a rustle of veined wings, and Shikari settled to a tighter mass. “Intelligence. It is indeed a mystery. But this — closeness and warmth — is without a doubt the best part of intelligence.”

While Chan and Shikari had been talking, full night had arrived. The pursuit team had set up its camp in a clearing, surrounded by the dusty blue-green vegetation of Barchan’s polar region. In the past few minutes the air temperature had dropped thirty degrees. Shikari was like a warm, soft blanket swaddling Chan up to his chin. He raised his head and stared up at the sky. Eta Cassiopeia’s brighter component had set, and the smaller sun of the binary was not yet risen. S’kat’lan, home planet of the Pipe-Rillas, was a bright point close to the horizon. Barchan’s dingy little moon sat above it in the sky, a shrunken irregular raisin.

Chan shivered. The night air was still warm. The tremor was one of apprehension. Three months ago he had lived in the quiet cocoon of the Gallimaufries, happy, ignorant, and near-brainless. Leah had shielded him from every danger. Now he was wandering the surface of an alien world, eighteen lightyears from home. He was not sure that he would ever see another sunset. Leah was even farther from Earth and facing much greater danger. By now she would be landing on Travancore, to face not a Simmie Artefact but the real Morgan Construct.

Given a choice, would he go back? Back to his mental vacuum, to the halcyon days of flowers and games?

One man had been the agent for all those changes, including the agony of the Tolkov Stimulator. If Chan closed his eyes he could see the face in front of him. Esro Mondrian deserved the blame — or the credit — for everything that had happened to Chan.

Turn back the clock? Chan stared up at Barchan’s solitary misshapen moon, and wondered: about Esro Mondrian, about Shikari, about intelligence, about himself.

By the time that the silver spark of S’kat’lan was sinking to Barchan’s dusty horizon, Chan had an answer. No matter what happened here, he would not choose to go back to his old life. Whatever burden the mixed blessing of self-awareness and intelligence brought with it, he wanted to carry it.

With that knowledge the urge for revenge on Esro Mondrian lost its focus. If the man had earned Chan’s hatred, perhaps he had also earned his gratitude. He had dragged Chan, reluctant and screaming, into the bright world of responsibility…

Chan drifted away to a mental state that was both remote and infinitely satisfying. His reverie was at last interrupted when the dark bulk of the Tinker stirred against him. He opened his eyes and discovered, incredibly, that a hint or dawn was already in the sky. Where had the night gone?

“Listen.” It was the voice of Shikari, deep and contented as a purring cat. “Do you hear it? The sound of the aircar. The others are returning, and we are sad. Our time of peace and closeness soon must end.”
