High Wizardry

Pattern Recognition

Nita popped out into a canopy of starlit darkness and a carpet of dim light, breathing very hard. Earth's gravity well was no joke: pushing her own mass and enough air to breathe for a while up out of that heavy pull was a problem. She walked over to a boulder, dusted it off, and sat down, panting, to admire the view while she waited for Kit.

The "usual place" where they met was, of course, the Moon. Nita liked it there; working, and thinking, were always easy there, in the great silence that no voices but astronauts' and wizards' had broken since the Moon's dust was made. This particular spot, high in the lunar Caucasus mountain chain, was a favorite of Kit's-a flat-topped peak in a wild, dangerous country of jagged gray-white alps, cratered and pocked by millennia of meteoric bombardment. Piles of rocktumble lay here and there, choking the steep valleys where the sheer heat and cold of the lunar days had been enough to flake solid rock away from itself in great glassy or pumicey chunks. Off to one side, the pallid rim of the little crater Calippus scraped razor-sharp against the sky, and over it hung the Earth.

The Moon was at first quarter, so the Earth was at third, a blinding half-world: blazing blue-green, almost painful to look at until the eyes got used to it. It shed a cool faint blue-white light over everything.

A curl of white stormweather lay over the northwestern Pacific, and there vanished; for down the middle of it the terminator ran, the edge of night, creeping ever so slowly toward the west. Most of North America lay in the darkness, and city lights lay golden in faint glittering splashes and spatters with brighter sparkling Patches under the Great Lakes and on the California coast.

Nita shrugged out of her knapsack, opened it and rechecked the contents. It was a good assortment: varied enough to handle several different classes of sPell, specific enough to those classes to let her save some power for herself.

She pulled her manual out and started paging through it for the "tracker" spell that she and Kit would need when he got here. It was actually a variant of the one he had threatened to put on Dairine in the city: this one hunted for the characteristic charged "string residue" left in space by the passage of a wizard's transit spell through it. Nita's specialty was astronomy, so she had been shocked to find that "empty" space wasn't actually empty, and even the hardest vacuum had in it what physicists called "strings," lines of potential force that have nothing to do with any of the forces physicists understand. Wizards, of course, could use them: much of what passes for telekinesis turns out in fact to be string manipulation.

The tracker spell made most elegant use of it. And once we find her, Nita thought, I'm gonna tie a few of those strings around her neck. .

But it didn't do to start a wizardry in such a mood. Nita pulled her space pen out of her pocket, kicked some of the larger rocks out of her way-they bounced off down the mountain as slowly as soap bubbles-and began drawing the circle for the transit spell.

It was becoming an old familiar diagram, this one. The basic circle, knotted with the wizard's knot: her own personal data, reduced by now (after much practice) to one long scrawl in the precise and elegant shorthand version of the Speech: Kit's data, another scrawl, over which she took even more care than her own. What a wizard names in the Speech, is defined so: inaccurate naming can alter the nature of the named, and Nita liked Kit just the way he was. A third long scrawl of shorthand for Picchu: Nita looked oddly at some of the variables in it, but Tom had given her the data, and he certainly knew what he was doing. Then the internal diagrams, the "intent" factors. The point of origin, the intended point of arrival or vector of travel; the desired result; the time parameters and conditional statements for life-support; the balloon-diagram for the ethical argument. .

Nita wiped sweat and grit off her face, and muttered at the incessant hissing in the background. Dust flew freely in one-sixth gravity, and got in everything: after you went to the Moon, you took a shower, for the same reasons you take one after a haircut. But there wasn't much more to do here. She finished the last few strokes of the notations in the environmental-impact statement and stood up, rubbing her back and checking her work for spelling errors.

It was all in order. But that hissing. .

She sat down again, feeling nervous. Facility with the Speech, as with any other language, increases with time. After several months of working in a sort of pidgin Speech, Nita was finally beginning to think in it, and the results were sometimes upsetting. Once upon a time, it had been quiet on the Moon when she visited. But no more. Her more accustomed mind heard a sound in the darkness now: a low low sound like a breath being let out, and out, and out forever. The astronomer part of her knew what it was-the so-called four-degree radiation that was all that was left of the universe's birth. Normally only radio telescopes set to the right frequency could hear it. But Nita wasn't normal. Nor was the sound just a sound to her. In it she could hear the sound of consciousness, life, as plainly as she had used to be able to hear Kit think. That sensitivity had decreased over time; but this one was increasing, it seemed in the deep silence, by the minute. It upset her. Suddenly the universe, that had seemed so empty, now felt crammed full of powers and intelligences that might not need planets, or bodies. And Dairine was out there in the middle of them, mucking around in her inimitable fashion. . Nita found herself wishing that Kit would hurry up. She very much wanted to see that cheerful face, to hear at least his voice, if not his sassy, loud cast of thought, always with that slight Hispanic accent to it…

Long time since we heard each other think. .

She had been wondering about that. Idly she began flipping through the manual, turning pages. Maybe the index- But the index did her no good: she couldn't think what heading to look under. "Come on," she muttered to the book, "give me a hand here, I don't have all day."

It was that hissing that was making her ill-tempered, she realized. A thought occurred to her, and she was glad she hadn't completely cleaned out her knapsack the other day. She reached into it and pulled out a tangle of cord, and a pair of earphones, and her Walkman. It was a Christmas present from her mother-the best of any present Nita had gotten last year, for she loved music and liked walking through her day with a soundtrack. Now she riffled through the pages of her manual, squinting at them in the pale Earth-light, while rock sang softly in the earphones.

Diagrams. . She skipped that whole section, not without another glance over at Kit's name scrawled in the motionless, powdery lunar dust. He was all there: at least, he seemed to think so-it was mostly the description of himself he had carefully worked out. Of course, after their first few spells Nita had looked over his shoulder and suggested a couple additions to the data-his fondness for chocolate ice cream (which he had instantly admitted), and his craziness for poetry, especially Shakespeare (which embarrassed him, and which he had refused to admit to for several days). The look on his face when I caught him reading The Tempest. Still, he admitted it, finally. . She smiled a little then. He hadn't taken long to point out that her data said nothing about the fact that she devoured horse books one after another, or that he had once caught her with a long stick in hand, having an energetic swordfight with one of the trees in the vacant lot. .

And where is he!

She sighed and glanced down at the pages that had fallen open in her hand. One of them said: Wizards in the closest relationships, leading toward permanent partnership, usually find that nonverbal communication becomes rare or difficult. Other conditions obtain for other species, but for human wizards, intimacy is meaningless without barriers to overcome-and to lower. Wizards usually have little need for such in the early stages of their careers. But as this situation changes, as the wizard becomes more adept at accurate description in the Speech, and therefore more adept at evaluating the people he or she works with, the wizard's mind typically adapts to the new requirements by gradually shutting out the person most

. . permanent partnership?

No. Oh, no

Nita swallowed with a throat suddenly gone dry, and slapped the book shut. For a moment she tried to do nothing but listen to the tape. It was something of Journey's-their distinctive sweet keyboards and synthesizers, wistful, singing down toward silence. And then the vocal: "Looking down I watch the night running from the sun; orphan stars and city lights fading one by one. .

Oh, sweet memories, I call on you now. ."

Of course, Nita thought, there was a lot of it going around school. Going steady, dating, pins and rings, all the silliness. Her mother had forbidden Nita to do any such thing, telling her she was much too young.

Nita didn't mind: it all seemed dumb to her. Sometimes, seeing how crazed some of the other girls her age were over the boy question, she wondered if she was normal. She was too busy, for one thing. She had something solider than going steady. When you were a wizard

— with a partner-

Oh, come on. It's not as if they're going to make you marry him or something! Look at Tom and Carl, they're just buddies, they work together because they enjoy doing it….

But I don't want. .

She trailed off. She didn't know what she wanted. Nita put her head down in her hands, trying to think.

No answers came: only more problems. Thoughts of Kit backing her up when she was terrified, cheering her up when she was annoyed, Kit being the solid, reliable voice in the other half of a spell the presence on the far side of the circle, matching her cadence exactly, for the fun and the challenge of it. What's wrong with that? What's wrong with having a best friend?

He's a boy, that's what. It's changing. I'm changing.

I'm scared.

She gazed up through unending night, down at oncoming morning, and tried to work out what to do. Has he noticed this happening to him too? And suppose he starts liking someone else better than me? Will he want to keep the team going? If only I knew what he was thinking. .

Then she let out a sad and annoyed breath. It's probably nothing, she thought. Everything is probably fine. .

". . oh, so much is wasted," sang the earphones, "and oh so little used! but the trick of the dreamer is keeping yourself from the blues-"

Hah, Nita thought. I wish it were that simple. . And the voice that sang cried out at her, so sudden and defiant that she sat erect with startlement

"Everyone's a hero if you want to be! Everyone's a prisoner holding their own key! And every step I take, every move I make, — I'm always one step closer I don't mind running alone!"

It was Steve Perry's fierce, clear voice, uplifted in almost angry encouragement, hitting the chorus hard.

He went on, singing something about children and concrete canyons, but Nita was still full of that startlement and hardly heard. Even Dairine, she thought. There's some job out there that only she can do.

… She had not thought of it in this light before, and the thought of Dairine as a hero staggered her, and annoyed her for a moment. Her? The runt?

But then Nita felt ashamed. What had she been herself, not more than a few months ago? Basically a coward, afraid of everything, including herself- friendless, quiet and smart but with no one to do any good by being so. Things were different now: but who was she to deny Dairine her chance at being more than she had been? And every step I take, every move I make, I'm always one step closer. .

And if she can do that, Nita thought after a moment, I can sure ask him what he thinks about things.

A sudden movement off to one side brought Nita's head around with a snap. In utter silence, silvery-white dust was kicking up in a vague pale cloud from where a tall man in a polo shirt and shorts was standing. Tom bounced over to where Nita sat, being careful of his footing. Nita admired the way he bounced: he had obviously had a lot of practice at the kangaroo hop that works well in low gravities.

He paused not too far from Nita to let her shieldspell recognize his and allow it to infringe, then sat down beside Nita on the boulder, casting an analytical eye over her spell diagram. "Very neat," he said. "Nice structure. Carl has been contaminating you, I see."

"Thanks."

"Kit just called me," Tom said, brushing dust off himself. "He'll be up in a few. . he's just settling things with his folks. I'm going to be talking to them later." Tom smiled wearily. "This seems to be my night."

"Yeah."

More silverdust kicked up, closer and to the right. There was Kit, with his knapsack over his back and Picchu on one shoulder. "All set," he said to Tom. He looked at Nita and said, "They hollered a lot. But I think my dad is proud. Mom seems pretty calm about it." Then he laughed, a little wickedly. "My sisters are in shock."

"Can't say that I blame them."

Nita got up, dusting herself off. "Okay," Tom said. "I wanted to see you two off up here, because there's data you'll need that your parents don't. Something major is going on out there. Dairine is not going to run into just some bunch of lackeys for the Lone Power out there. That one Itself is after her. But I have no indication why. And Its power is oddly veiled, at the moment-concentrated, and hidden. I don't think this manifestation of the Lone Power is going to be as obvious as it has recently. So find Dairine, and look carefully at the situation. If it looks like she needs to be where she is, stay with her and do what you can for her."

He paused. "But you are going to have to be very careful. The Lone One won't mind distracting her by striking at you two… or using her danger to sucker you into pulling her out of the problem she's intended to correct. Use your judgment. Save her if you can."

"And if we can't?" Kit said.

Tom looked at him sadly. "See that the job gets done," he said, "whatever it is."

They were both quiet.

"There's no telling what the stakes are on this one," Tom said. "The looks of the situation may be deceiving. . probably will. Can you take this job and do it? Don't go if you can't. If either of you isn't sure you can depend on yourself, or on the both of you, I don't want you in this. Too much can go wrong."

Kit looked at Nita, then back at Tom. "It's cool," he said.

Nita nodded. Tom looked at her.

"I know," he said. "You're upset about her. All right. . you'll have a while to shake down, while you chase her. Meantime, Carl and I have sent word ahead through the Network, so that a lot of people will be expecting you." He smiled. "You're going to find that the way wizards have to behave on Earth is the exception rather than the rule. Most of the major law-enforcement bodies in this part of the Galaxy routinely call wizards in for consultations, and they owe us a lot of favors. So don't be afraid to ask the authorities wherever you go for help. Odds are you'll get it."

"Okay."

"So get out of here. And good hunting."

"Thanks."

"Come here, bird," Tom said to Picchu. Nita looked up in surprise, expecting an explosion: Picchu did not take orders. She was surprised to see the macaw clamber up onto Tom's arm and reach up to nibble his ear. Tom scratched her in the good place, on the back of the head, and she went vague in the eyes for a couple of minutes, then ruffled the neck feathers up and shook herself. "You be careful," Tom said.

"I'll be fine," Picchu said, sounding cranky.

Nita repacked her knapsack, slung it on, and flipped her manual open to the marked pages with the verbal supplement for the transit spell as Tom passed Peach back to Kit. She caught Kit's eye, stepped into the circle at the same time he did. Tom backed away. Slowly, and in unison, they began to read, and the air trapped in their shieldspells began to sing the note ears sing in silence. .

As the spell threw them out of the Solar System, Nita wondered whether she would ever see it again. .

"Dead," Dairine whispered. "I'm dead for sure."

"Input error," said the computer, sounding quite calm.

Dairine's heart leapt. "Are you busted?!" she cried.

"Syntax error 24," said the computer, "rephrase for-"

"You can take your syntax errors and. . never mind!" Dairine said. "What's wrong with you?

Diagnostic!"

"External input," said the computer. "Nontypical."

"What is it? Some kind of broadcast?"

"Negative. Local."

It happened right after it linked to the geothermal power, Dairine thought. "Check your link to the planet," she said.

"Affirmative. Positive identification. External input. Planetary source."

"Are there people here?" Dairine said, looking around hurriedly.

"Negative." The computer's screen kept filling up with 1's, clearing itself, filling with 1's again.

She held still and forced herself to take a deep breath, and another. The computer wasn't broken, nothing horrible had happened. Yet. "Can you get rid of all those ones?" she said to the computer.

"Affirmative."

The screen steadied down to the last she had been looking at. Dairine stared at it.

This unique structure becomes more interesting when considering the physical nature of the layering.

Some 92 % of the layers consist of chemically pure silicon, predisposing the aggregate to electroconductive activity in the presence of light or under certain other conditions. This effect is likely to be enhanced in some areas by the tendency of silicon to superconduct at surface temperatures below K. There is also a possibility that semiorganic life of a "monocellular" nature will have arisen in symbiosis either with the silicon layers or their associated "doping" layers, producing Dairine sat there and began to tremble. It's the planet, she thought. Silicon. And trace elements, put down in layers. And cold to make it semiconduct.

"It's the planet!" she shouted at the computer. "This whole flat part here is one big semiconductor chip, a computer chip! It's alivel Send it something! Send it some 1's!"

The computer flickered through several menu screens and began filling with 1's again. Dairine rolled from her sitting position into a kneeling one, rocking back and forth with anxiety and delight. She had to be right, she had to. One huge chip, like a computer motherboard a thousand miles square. And some kind of small one-celled-if that was the right word-one-celled organism living with it. Something silicon-based, that could etch pathways in it-pathways that electricity could run along, that data could be stored in.

How many years had this chip been laying itself down in the silence, she wondered? Volcanoes erupting chemically pure silicon and trace elements that glazed themselves into vast reaches of chip-surface as soon as they touched the planet: and farther down, in the molten warmth of the planet's own geothermal heat, the little silicon-based "bacteria" that had wound themselves together out of some kind of analogue to DNA. Maybe they were more like amoebas than bacteria now: etching their way along through the layers of silicon and cadmium and other elements, getting their food, their energy, from breaking the compounds' chemical bonds, the same way carbon-based life gets it from breaking down complex proteins into simpler ones.

It was likely enough. She would check it with the manual. But for now, the result of this weird bit of evolution was all that really mattered. The chip was awake. With this much surface area-endless thousands of square miles, all full of energy, and connections and interconnections, millions of times more connections than there were in a human brain-how could it not have waked up? But there was nowhere for it to get data from that she could see, no way for it to contact the outside world. It was trapped. The

1 's, the basic binary code for "on" used by all computers from the simplest to the most complex, were a scream for help, a sudden realization that something else existed in the world, and a crying out to it. Even as she looked down at the screen and watched what the computer was doing, the stream of 1's became a little less frantic. 111111111, said her own machine. 111111111, said the planet.

"Give it an arithmetic series," Dairine whispered.

1, said her computer. 11. 111. 1111. 11111.

1. 11. 111. 1111. 11111.

"Try a geometric."

1. 11. 1111. 11111111. 1111111111111111.

I. 11. 1111. 11111111-

Oh, it's got it," Dairine said, bouncing and still hugging herself. "I think. It's hard to tell if it's just repeating. Try a square series."

II. 1111. 1111111111111111-

III. 111111111. 1111111111111111111111111-

It had replied with a cube series. It knew, it knewl "Can you teach it binary?" Dairine said, breathless.

"Affirmative." 1. 10. 11. 100. 101-

Things started to move fast, the screen filling with characters, clearing itself, filling again as the computers counted at each other. Dairine was far gone in wonder and confusion. What to teach it next? It was like trying to communicate with someone who had been locked in a dark, soundless box all his life. . "Is it taking the data?"

"Affirmative. Writing to permanent memory."

Dairine nodded, thinking hard. Apparently the huge chip was engraving the binary code permanently into itself: that would include codes for letters and numbers as well. But what good's that gonna do? It doesn't have any experiences to make words out of, no reason to put letters together to make the words in the first place… It was like it had been for Helen Keller, Dairine thought: but at least Helen had had the senses of touch and taste, so that she could feel the water poured into her hand while her teacher drummed the touch-code for water into it. It has no senses. If it did.

"Can you hook it into your sensors?" she said to the computer.

The computer hesitated. It had never done such a thing before: and when it spoke again, its syntax was peculiar-more fluid than she was used to.

"High probability of causing damage to the corresponding computer due to too great a level of complexity," it said.

Dairine breathed out, annoyed, but had to agree. Anything able to sense events happening forty trillion miles away, no matter how it managed it, was certainly too complex to hook directly to this poor creature right now. And another thought occurred to her, and her heart beat very fast. Not sensors, then. Senses.

"Can you hook me to it?" she said.

This time the hesitation was even longer, and Dairine stared at the computer, half expecting it to make an expression at her. It didn't, but the speech of its response was slow. "Affirmative," it said. "Triple confirmation of intent required."

"I tell you three times," Dairine said. "Hook it to me. Tell me what to do. It has to get some better idea of what's going on out here or it'll go crazy!"

"Direct physical contact with surface," the computer said. It sounded reluctant.

Dairine dusted her hands off and put them flat on the glassy ground.

She was about to open her mouth to tell the computer to go ahead, do what it was going to: but she never got the chance. The instantaneous jolt went right through her with exactly the same painless grabbing and shaking she had felt when she was seven and had put a bobby pin in the electric socket.

She convulsed, all over: her head jerked up and snapped back and she froze, unable even to blink, staring up into the golden-veiled blaze of the barred spiral, staring at it till each slight twitch of her eyes left jittering purple-green afterimages to right and left of it; and somewhere inside her, as if it were another mind speaking, she could hear her computer crying 110010 01011110000100! 11001001011110000100! at the frantic silence that listened. Light, light, light-

And the reply, she heard that too: a long, crazed string of binary that made no sense to her, but needed to make none. Joy, it was simply joy, joy at discovering meaning: joy so intense that all her muscles jumped in reaction, breaking her out of the connection and flinging her facedown on the glazed ground.

The connection reestablished itself and Dairine's mind fell down into turmoil. She couldn't think straight: caught between the two computers -for under the swift tutelage of her own, the great glassy plain was now beginning truly to function as one-she felt the contents of her brain being twinned, and the extra copy dumped out into endless empty memory and stored, in a rush of images, ideas, occurrences, communications, theories and raw sensations. She knew it took only a short time: but it seemed to go on forever, and all her senses throbbed like aching teeth at being desperately and delightedly used and used and used again to sense this moment, this ever-changing now. Dairine thought she would never perceive anything as completely again as she was seeing and feeling the green-and-gold-shaded piece of silicon aggregate she lay on, with the four crumbs from her sandwich lying half an inch from her eye. She felt sure she would be able to describe the shape of those crumbs and the precise pattern of the dappling in the silicon on her deathbed. If she survived this to have one.

Finally it stopped. Groaning softly, Dairine levered herself up and stared around her. The computer was sitting there innocently, its screen showing the main "Manual" menu. "How is it?" Dairine said, and then sighed and got ready to rephrase herself.

"Considerably augmented," said the computer.

Dairine stared at it.

"Is it just me," she said, "or do you sound smarter than you have been?"

"That calls for a value judgment," said the computer.

Dairine opened her mouth, then closed it again. "I guess it does," she said. "You weren't just acting as conduit all through that, were you? You expanded your syntax to include mine."

"You got it," said the computer.

Dairine took a moment to sit up. Before this, she'd thought she would love having the computer be a little more flexible. Now she was having second thoughts. "How's our friend doing?"

"Assimilating the new data and self-programming. Its present running state has analogues to trance or dream states in humans."

Dairine instantly wished it hadn't said that. What time was it at home? How long had she been running?

How long had that last longest jump taken, if it had in fact taken any time at all? All she knew was that she was deadly tired.

"Update," said the computer. "It is requesting more data."

"On what?"

"No specific request. It simply desires more."

"I'm fresh out," Dairine said, and yawned. Then she looked at the computer again. "No, I'm not. Give it what you've got."

"Repeat and clarify?" said the computer, sounding slightly unnerved.

"Give it what you've got. All the information about planets and species and history and all the rest of it.

Give it the magic!"

The computer said nothing.

Dairine sat up straight. "Go on," she said.

No reply.

"Is there some rule that says you shouldn't?"

"Yes," said the computer slowly, "but this edition of the software contains the authorization-override function."

"Good," Dairine said, none too sure of what this meant, except that it sounded promising. "I'm overriding. Give it what you've got."

The screen lit up with a block of text, in binary, quite small and neat, and Dairine immediately thought of the Oath in Nita's manual.

The screen blanked, then filled with another brief stream of binary. That blanked in turn, and screenful after screenful of 1's and O's followed, each flickering out of existence almost as quickly as it appeared.

Dairine got up and stretched, and walked back and forth for a few minutes to work the kinks out of her muscles. She ached all over, as she had after the bobby pin incident, and her stomach growled at her again: a bologna sandwich and a half was not enough to satisfy her after the kind of day she had had. If it was even the same day. At least I have a while before the BEMs show up, she thought. Maybe our new friend here can be of some kind of help… As she looked out across the dappled-silvery plain, there was a bloom of soft crimson light at one side of it. Dairine held still to watch the sun rise. It was a fat red star, far along in its lifetime-so far along, so cool, that there was water vapor in its atmosphere, and even in the vacuum of space it hung in a softly glowing rose-colored haze, like an earthly summer sunset. It climbed the sky swiftly, and Dairine watched it in silence. Quite a day, she thought. But whether it's morning here or not, I need a nap.

She turned around and started to head back toward the computer-and froze.

One patch of the surface was moving. Something underneath it was humping upward, and cracks appeared in the perfect smoothness. There was no sound, of course, since Dairine's air supply was nowhere near the spot; the cracks webbed outward in total silence.

And then the crust cracked upward in jagged pieces, and the something underneath pushed through and up and out. Bits of silica glass fell slowly in the light gravity and bounced or shattered in a snow of splinters around the rounded shape that stood there. Stood was the right word: for it had legs, though short stumpy ones, as if a toy tank had thrown away its treads and grown limbs instead. It shook itself, the rounded, glassy, glittering thing, and walked over to Dairine and through her shields with a gait like a centipede's or a clockwork toy's; and it looked up at her, if something like a turtle with no head can be said to look up.

"Light," it croaked, in a passable imitation of the computer's voice, and bumped against her shin, and rested there.

It was too much. Dairine sat down where she was and looked at the computer. "I can't cope," she said.

The computer had no reply for this.

"I can't," she said. "Make me some more air, please, and call me if they start chasing us again."

"No problem," said the computer.

She lay down on the smooth glassy ground, gazing at the rounded, glittery I: thing that stood on its fourteen stumpy legs and gazed back at her. No more than six breaths later she was asleep.

So she did not see, an hour and a half later, when the sun, at its meridian, began to pucker and twist out of shape, and for the best part of the hour lost half of itself, and shone only feebly, warped and dimmed.

Her companion saw it, and said to the computer:

"What?"

"Darkness," said the computer: and nothing more.

Reserved Words

They got to Rirhath B early in the evening, arriving at the Crossings just after suns' set and just as the sky was clearing. Nita and Kit stood there in the Nontypical Transit area for a few moments, staring up at the ceiling like the rankest tourists. Picchu sat on Kit's shoulder, completely unruffled, and ignored everything with yawning scorn, though the view through the now-clear ceiling was worth seeing.

"My brains are rattled," Kit said, breathing hard. "I need a minute." So did Nita, and she felt vaguely relieved that Kit had said something about it first: so she just nodded, and craned her neck, and stared up. The view was worth looking at-this sudden revelation of Rirhath's sky, a glorious concatenation of short-term variable stars swelling and shrinking like living things that breathed and whose hearts beat fire.

All over the Crossings, people of every species passing through were pausing, looking up at the same sight, and admiring the completeness with which a perfectly solid-seeming ceiling now seemed to have gone away. Others, travelers who had seen it all before or were just too tired to care, went on about their business and didn't bother to look.

"We only have a couple of days," Picchu said, chewing on the collar of Kit's shirt.

"Peach," Nita said, "shut your face. You better?" she said to Kit.

"Yeah," he said. "You?"

"I was dizzy. It's okay now."

"Super." He flipped through his manual, open in his hand, and came up with a map of the Crossings.

"What do we need to find?"

"Stationmaster's office."; "Right." "f They checked out of Nontypical Transit, leaving their origin-and-destina tion information with the computer at the entrance, and set out across the expanse of the terminal floor, looking around them in calm wonder: for though neither of them had ever been there, both had read enough about the Crossings in their manuals to know what to expect. They knew there had been a time when the Crossings itself was only a reed hut by a riverside, and the single worldgate nearby only a muddy spot in a cave that the first Master stumbled upon by accident, and claimed for its heirs (after waiting several years on Ererikh for the gate to reverse phase so that he could get home). Now, a couple of thousand years' worth of technology later, worldgates were generated here at the drop of a whim, and the Stationmaster regulated interstellar commerce and transportation via worldgating for the entire Sagittarius Arm.

Its office was not off in some sheltered spot away from the craziness, but out in the very middle of the station floor: that being the spot where the hut had been, twenty-four hundred and thirty years before. It was only a single modest kiosk of tubular bluesteel, with a desk behind it, and at the desk, hung up in a rack that looked like a large stepstool, was a single Rirhait, banging busily on a computer terminal keypad and making small noises to itself as it worked.

Nita and Kit stopped in front of the desk, and the Rirhait looked up at them. Or more or less up: some of its stalked eyes looked down instead, and a few peered from the sides. It stopped typing. "Well?" it said, scratchy-voiced — understandable, Nita thought, when you've got a gullet full of sand.

"You're the Stationmaster?" Kit said.

"Yes," said the Rirhait, and the fact that it said nothing else, but looked at Kit hungrily, with its scissory mandibles working, made Nita twitch a little.

"We are on errantry, and we greet you," Nita said: the standard self-introduction of a wizard on business. Sir or Madam, one normally added, but Nita wasn't sure which the Master was, or even if either term applied.

"That too?" said the Master, looking at Picchu.

"Yes, that," said Peach, all scorn.

"Well, it's about time you people got here," said the Master, and left off what it was doing, standing up.

"Standing" was an approximation: a Rirhait is shaped more like a centipede than anything else, so that when it got off its rack and came out from behind the desk, its long, shiny silver-blue body only stood a foot or so off the ground, and all its eyes looked up at them together. "We had more of an untidiness here this afternoon than we've had for a greatyear past, and I'll be glad to see the end of it."

Nita began to sweat. "The wizard who came through here earlier was on Ordeal," Kit said. "We'll need your help to find the spot from which she went farther on, so that we can track her: there are too many other world-gates here, and they're confusing the trail."

"She didn't cause any trouble, did she?" Nita said.

"Trouble?" said the Stationmaster, and led them off across the bright floor, and showed them the place where several large pieces of the ceiling had been shot down. "Trouble?" it said, pointing out the places where the floors were melted, indicating the blaster scars in the kiosks, and the large cordoned-off area where maintenance people of various species were scraping and scrubbing coffee ground-smelling residue off the floor. "Oh, no trouble. Not really."

Picchu began to laugh, a wicked and appreciative sound.

Nita blushed ferociously and didn't say anything for several minutes. The Rirhait led them off to another area of the floor which was closed in on itself by an arrangement of bluesteel kiosks. This was Crossings security; various desks stood about inside it, with creatures of several species working at them. The Master led them to one of the unoccupied desks, a low flat table full of incomprehensible equipment.

"Here," it said, and reared up on its back ten legs to touch the machinery in several places.

Small and clear, an image appeared above the table: remote, but equally clear, sound accompanied it.

Nita and Kit found themselves looking at the Crossroads equivalent of a videotape, but in three dimensions, with neat alien characters burning in the lower corner of it to show the time and location at which the recording was made. They watched a group of toadlike BEMs make their way across the terminal floor, spot Dairine, head off in pursuit. They watched Dairine deal with the deinonychus, and afterward with the BEM that grabbed her. Nita gulped.

"They look like Satrachi," Kit said, astonishingly cool-voiced.

Nita's eyebrows went up. Alien species were her specialty: evidently Kit had been doing some extra research. "They are, as far as we can tell," said the Master. "The one of them whom we have in custody has valid Satra identification."

"We'll need to see this person, then," Nita said. The tape ran: Nita watched Dairine's dive into the bar, and from another camera angle, her sister's reemergence into the terminal and dash into the rest room.

Nita groaned, recognizing the room by the symbol on its door as a spawning room for any one of several species that gave birth to their young on the average of once every few days, and were likely to be caught short while traveling on business. Nita hoped that Dairine hadn't introduced one of the species involved to a completely new kind of birth trauma.

"That was the spot she left from?"

"Yes, Emissary." It was the first time Nita had ever been formally called by one of the twenty or so titles commonly used for wizards, but she was too busy now to enjoy it. She glanced at Kit. He was frowning at the image hanging in the air: finally his concentration broke and he glanced at her.

"Well?" he said. "You want the Satrachi?"

"I'd better," she said, though she very much wanted not to-the looks of the Satrachi gave her the creeps.

But dealing with live things was her department: the handling of machinery and inanimate objects was Kit's. "You go ahead and check the room out. Stationmaster, can you have someone show me where it's being held?"

"Step on that square there," said the Master, pointing one eye at a spot on the floor: "it's direct transit to Holding. Emissary, I'll show you to the room in question. . "

Nita stepped on the block quickly before she would have time to change her mind.

Fifteen minutes with it told her all she needed to know: the Satra was a dupe, it and its friends-a small paramilitary club-deluded into pursuing Dairine by some agent of the Lone One. It's the usual thing, she thought as she headed back to Kit and the Stationmaster. The Power never comes out in the open if it can find some way to make someone else do Its dirty work. Preferably an innocent: that way it's more of a slap in the Bright Powers' face. Unusual, though, that it used a whole group this time. Normally it's hard to keep that subtle a grip on a whole group's mind: one of them slips free, or perceives it as control. . and when that happens, odds are that the whole group is useless for Its purposes.

She strolled among aliens and their luggage and finally came to the little Grand Central-size alcove where Dairine's rest room was. Its door was frozen in the dilated mode. Nita slipped in and found Kit and Picchu and the Master off to one side, examining one particular birthing-booth. It seemed to have had its door burned off, and the back of the booth was blistered and pocked with an ugly rash of blaster scars.

For a good second or so her breath refused to come. "She jumped after that?" Nita finally managed to say.

Kit looked over his shoulder at her. "Neets, relax, there are no bloodstains."

"There wouldn't be, with blasters," Nita said. "They cauterize."

"Any really big wound would spurt anyway," Kit said, straightening up and starting to through his manual. "I think they missed her. The tiles don't remember her screaming, and not even Dairine's that stoic." He kept turning over pages.

"How far did she go?"

"A long jump," Kit said. "Multistage, from the feel of it. They must have freaked her out pretty good." He looked up. "That computer she's got leaves a definite sense of what it's been doing behind it. Can you feel it?"

Nita let her eyes go unfocused for a moment and blanked her mind out, as she might do to hear the thinking of some particularly quiet tree. Some residue of Dairine's emotion still hung about the strings in the space-time configuration of the area, like tatters on a barbed-wire fence: fear and defiance, all tangled up together; and alongside her tatters, others, ordered and regular, a weave less vivid and complex in different ways. "It feels alive," Nita said to Kit after a while. "Do computers usually feel that way?"

"I don't know," Kit said, sounding annoyed. "I never tried feeling one before this. . You got your widget?" he said. "We're gonna need it to catch up with her and her friends."

"Yeah." She unslung her pack and started rummaging for the gimbal.

"Well, I have things to do," said the Master. "If you need anything, ask one of the security people, they're all over." And without staying for farewells, it went flowing out the door in a hundred-legged scurry.

Nita glanced after it, then back at Kit, and shrugged. "Here," she said, and tossed him the gimbal.

"Which spell are you thinking of using?"

"That dislocator on page 1160."

She got out her own manual and found the page. "That's awful long-range, isn't it? Her next jump must have been shorter than that."

"Yeah, but Neets, who wants to leapfrog one step behind the things that are chasing her! We want them, right now-we want them off her rear end, so she can do whatever it is she needs to do without interference." He looked grim. "And when we find 'em-"

Nita sighed. "Forget it," she said, "they're dupes."

Kit looked up at her while getting a grease pencil out of his pack. "It suckered them in?"

She filled him in on what the Satrachi had told her as Kit got down on the tiles and began drawing their transit circle. Kit sighed a little. "I was hoping it was some of the Lone One's own people," he said, "so we could just trash 'em and not feel guilty."

Nita had to smile a little at that. Picchu climbed down from the partition between the booths, where he had been sitting, and clambered onto Nita's shoulder. "Get mine right," she said to Kit. "I don't want to come out the other side of this transit with fur."

Kif shot a look at Picchu, and didn't need to comment; Nita could imagine what he was thinking. "Come sit over here, then, if you're so worried," he said.

To Nita's amusement Peach did just that, climbing backward down her arm and over onto Kit's back, where she peered over his shoulder. "Not bad," she said, looking at the diagram.

Kit ignored this. "So make yourself useful. Is anything bad going to happen to us?"

"Of course it is," Picchu said., "You might be more specific."

"And I might not need to. The Power that invented death is going to be on your tails shortly. Our tails," she added, looking over her shoulder at the splendid three-foot sweep of scarlet feathers behind her.

"Even you two should be able to see that coming."

Kit changed position suddenly, and Picchu scrabbled for balance, flapping her wings and swearing.

"Like you should have seen that?"

Nita grinned a little, then let it go: her mind was back on the train of thought she had been playing with out in the terminal. "I was wondering about that, a while back," she said to Kit. "It invented death, when things were first started. But that wasn't enough for It. It had to get people to buy into death-not just the dying itself: the fear of it."

Kit nodded. "But a lot of species have opted out, one way or another. I mean, we're scared to die. But we still suspect there are reasons not to be scared. A lot of people do. Its hold isn't complete anymore."

"I know. Kit, do you think-Tom said something was about to 'tip over.' Some major change. Do you think what he meant was that the Lone One was about to lose completely somewhere?"

"He always said," Kit said, "that what happens one place, spreads everyplace else. Everything affects everything, sooner or later. The manual says so too. A few times."

Nita nodded, thinking how unusual it was for the manual to repeat itself about anything. "And the pattern started shifting, a couple thousand years ago," Kit said. "The Lone Power had always won completely before. Then It started having wins taken away from It after the fact."

Kit looked reflective. "If somewhere or other, It's about to lose-right from the start…"

Nita looked at him sidewise. "Then It starts losing at home, too, in all the little daily battles. Eventually."

Kit nodded. "Dairine," he said.

Nita shook her head, still having trouble believing it-but having to admit the likelihood. Somehow, her sister had a chance of actually defeating the Lone Power. She must have a chance: It wouldn't be wasting energy on her otherwise. "Why her?" Nita said softly.

"Why you?" said Picchu, cranky. "What makes either of you so special, that you can even come away from an encounter with That alive? Don't flatter yourself: It's eaten stars and seduced whole civilizations in Its time. You were simply exactly the right raw material for that particular situation to use to save Itself."

"I didn't mean that, I guess," she said. "I meant, why now? The Lone Power has been pulling this kind of stunt on planets for as long as intelligence has been evolving. It comes in, It tries to get people to accept entropy willingly, and then It bugs off and leaves them to make themselves more miserable than even It could do if It worked at it. Fine. But now all of a sudden It can be beaten. How come?"

Picchu began chewing on Kit's top button. "You know," she said, "that's part of the answer. Granted, It's immortal. But It doesn't have infinite power. It's peer to all the Powers, but not to That in Which they move. And even an immortal can get tired."

Nita thought about that. Five billion years, maybe ten, of constant strife, of incomplete victories, of rage and frustration-and yes, loneliness: for the Lone One, she had discovered to her shock, was ambivalent about Its role- after all that, surely one might not be as strong as one had been at the start of things. .

Kit got the button out of Picchu's mouth, and was nipped for his trouble. "So, after all these near losses, It's tired enough to be beaten outright?"

Picchu got cranky again. "Of course! It was that tired long ago. The Powers wouldn't need Dairine for just that. They could do it Themselves, or with the help of older wizards. But haven't you got it through your head?.They can't want to just beat the Lone One. They must think there's a better option."

Nita looked at Picchu, feeling half frightened. "They want It to surrender," she said.

"I think so," said Picchu. "I suspect They think she could get the Lone One to give in and come back to Its old allegiance. If It does that… the effect spreads. Slowly. But it spreads everywhere."

Picchu climbed down off Kit's shoulder and pigeon-toed across the floor, heading for a receptacle with some water in it. Kit and Nita both sat silent. The possibility seemed a long way from coming true. A world in which the universe's falling into entropy slowly stopped, affecting people's relationships with one another, a world gradually losing the fear of death, a world losing hatred, losing terror, losing evil itself…

it was ridiculous, impossible, too much to hope for. But still, Nita thought, if there was any chance at all

…!"… On the news last night," Kit said, "did you see that thing about the car in Northern Ireland?"

"No."

"They hijack cars over there sometimes, as a protest," he said. "One side or the other." There was something about his voice that made Nita look at him hard. "Sometimes they set the cars on fire after they hijack them." Kit sat looking in front of him at nothing in particular, looking tired. "You know the kind of wire screen you get for station wagons, so that your dog can be in the back and not get into everything?"

"Yeah."

"Someone hijacked a car with one of those in it, the other night. With the dog in it, in the back. Then they set the car on fire. With the dog in it."

Nita went ashen. Kit just kept looking at nothing in particular, and she knew what he was thinking of: Ponch, in Kit's dad's station wagon, lying around in the back too contented and lazy even to try to get into the grocery bags all around him. And someone coming up to the car-"Neets," Kit said, after a while, "Bad enough that they kill children, and grown-ups, and don't even care. But the poor dogs too-if we really have a chance to stop that kind of thing, I'll do… whatever. I don't care. Anything."

She looked at him. "Anything!'"

He was quiet for a long time. "Yeah."

Eventually she nodded. "Me too."

"I know," he said.

She looked at him in surprise. "Well, look at what you did with the whales," he said.

Nita's mouth was very dry. She tried to swallow. It didn't work.

"I mean, you did that already. That's what it was about. The Power got redeemed, a little: we know that much. Or at least It got the option to change. You did it for that. You almost got yourself killed, and you knew that might happen, and you did it anyway. Oh, I know you did it for me, some." He said this as if it were unimportant. "I was in trouble, you got me out of it. But mostly you did it to have things in the world be safe, and work."

She nodded, completely unable to speak.

"It seems like the least I can do," he said, and went no further, as if Nita should know perfectly well what he meant.

"Kit," she said.

"Look, I mean, I don't know if I can be that brave, but-"

"Kit, shut up."

He shut, rather astonished.

I'm always one step closer, sang memory at her from the Moon. "Look," she said, "I didn't do it for you 'some.' I did it for you 'pretty much.' "

Kit looked at her with an expression that at first made Nita think Kit thought she was angry with him.

But then it became plain that he was embarrassed too. "Well," he said, "okay. I-thought maybe you did.

But I didn't want to say anything because I didn't know for sure. And I would have felt real stupid if I was wrong." He had been looking away. Now he looked at her. "So?"

"So," and her voice stuck again, and she had to clear her throat to unstick it. "I like you, that's all. A lot.

And if you start liking somebody that much, well, I still want to keep the team going. If you do. That's all."

He didn't say anything. Nita stood there burning in a torment of embarrassment and anger at herself.

"Neets. Cut me some slack. You're my best friend."

Her head snapped up."… I thought it was Richie Sussman."

Kit shrugged. "We just play pool a lot. But it's the truth." He looked at her. "Isn't it true for you?"

"Yeah, but-"

"So why does that have to change? Look, we've got junk to do. Let's shake on it. We'll be best friends forever. And a team."

He said it so casually. But then that was how Kit did things: the only thing that wasn't casual was the way he worked to do what he said he would. "What if something happens?" Nita said. "What if-"

Kit finished one symbol inside the circle, shut the book, and stood up. "Look," he said, "something always happens. You still have to promise stuff anyway. If you have to work to make the promises true.

" He shrugged, hefted the manual. "It's like a spell. You have to say the words every time you want the results. Neets, come on. Shake on it."

They shook on it. Nita felt oddly light, as if her knapsack had been full of rocks and someone had come up behind her and dumped them out.

"Okay," Kit said. "Peach, where-good Lord."

Picchu was sitting in the water receptacle on the floor, flapping around and showering everything within range. "Do you mean I'm going to have to go halfway across the Galaxy with a soggy bird sitting on me?"

Kit said. "No way. Neets, it's your turn to carry her."

"You're getting a lot like Tom," said Picchu.

"Thanks!"

"That wasn't intended as a compliment."

Peach shook her feathers, scattering water. "Stop your complaining," she said to Kit. "The Powers only know when I'm going to have another chance for a bath." She stepped out of the low basin and shook herself again all over.

Nita wiped a drop out of her eye. "Come on," she said, and got Peach off the edge of the basin. "Kit, we set?"

"Yup. You want to do a defense spell, do it now. Peach? Any bad feelings?"

"All of them," Picchu said, "but nothing specific. Let's go."

They all three got into the circle. Kit knotted it closed with the figure-eight wizard's knot, dropped the gimbal into the circle on the spot marked out for it, then picked up his manual and began to read. Nita silently recited her favorite shieldspell, the one that could stop anything from a thrown punch to an ICBM, and for safety's sake set it at ICBM level. Then she got her own manual open and caught up with Kit.

The air began to sing the note ears sing in silence; the air pushed in harder and harder around them, Nita's ears popped, and the spell took hold and threw them off the planet-not before Nita saw a portly Me! thai gentleman peek in the door to see if it was safe to come in and have his child. .

There was a long, long darkness between the world winking out and flashing back into existence again.

Nita could never remember its having taken so long before-but then the jump from Earth to Rirhath had been a short one no more than fifteen or twenty light-years. She held her breath and maintained control, even while the back of her brain was screaming frantically, He made a mistake in the spell somewhere, you distracted him and he misspelled something else: you're stuck in this and you're never going to get out, never

It broke. Nita was as dizzy as she had been the last time, but she was determined not to wobble. Her ears stopped ringing as she blinked and tried to get her bearings. "Heads up, Neets," Kit was saying.

It was dark. They stood on some barren unlit moon out in the middle of space. Nothing was in the sky but unfamiliar stars and the flaming, motionless curtain of an emission nebula, flung across the darkness like a transparent gauze burning in hydrogen red and oxygen blue. Kit pointed toward the horizon where the nebula dipped lowest. Amid a clutter of equipment and portable shelters of some kind, there stood a small crowd of Satrachi. They had apparently not noticed their pursuers' appearance.

"Right," Nita said. "Let's do this-"

"Move us!" Picchu screeched. "Do it now!"

Kit's eyes widened. He started rereading the spell, changing the end coordinates by a significant amount.

Peach was still flapping her wings and screaming. "No, that's not far enough-"

Nita snatched the gimbal up from the ground and tied it into her shield-spell. Can it take the strain of two spells at once? We'll find out. It'll abort the one it can't manage, anyway. She gulped. Physical forces-

She started reciting in the Speech, naming every force in the universe that she could think of, tying their names into her shield and forbidding them entrance. Can I pull this off? Is this one of the spells that has a limit on the number of added variables? Oh Lord, I hope not

"Light," Peach was screaming at her, "light, lightl"

Nita told the shield to be opaque-and then wondered why it wasn't, as the brightest light she had ever imagined came in through it anyway. She had been to a Shuttle launch, once, and had come to understand that sound could be a force, a thing that grabbed you from inside your chest and shook you effortlessly back and forth. Now she wondered how she had never thought that light might be able to do the same, under some circumstances. It struck her deaf and dumb and blind, and she went sprawling.

Heat scorched her everywhere; she smelled the rotten-egg stink of burning hair. She clutched the gimbal: she couldn't have dropped it if she'd tried.

Much later, it seemed, it began to get dark. She opened her eyes and could not be sure, for a few minutes, that they were open, the world was so full or afterimages. But the purple curtain between her and everything else eventually went away. She and Kit and Peach were hanging suspended, weightless in empty space. At least it was empty now. There was no sign of any moonlet — only off to one side, a blinding star that slowly grew and grew and grew and grew, toward them. They were out of its range now. They had not been before.

"Didn't know the gimbal could handle both those spells," Kit said, rubbing his eyes. "Nice going."

"It won't do it twice," Nita said. There was just so much power one could milk out of a physical aid, and she had been pushing her odds even trying it once. "Where are we?"

"I haven't the faintest. Somewhere a light-month out from our original position. And those Satrachi were bait," he said. "For us. Look at it, Neets."

She looked. "I could have sworn I opaqued this shield."

"It is opaqued," Kit said. "But a shield doesn't usually have to put up with a nova at close range.

H-bombs are about the most one can block out without leakage, if I remember."

Nita stared at the raging star, all boiling with huge twisted prominences. For all its brilliance, there was a darkness about its heart, something wrong with the light. In a short time this terrible glory would be collapsed to a pallid dwarf star, cooling slowly to a coal. She shivered: one of the oldest epithets for the Lone Power was "Starsnuffer." It blew a whole star, just to kill us, because we were going to help Dairine. . "Did this system have other planets?" she said.

"I don't know. I doubt It cared."

And this was what was going after her little sister.

The anger in Nita got very, very cold. "Let's go find her," she said.

Together they began to read.

Fatal Error

Dairine woke up stiff and aching all over. . 's wrong with the bed? was her first thought: it felt like the floor. Then she opened her eyes, and found that she was on the floor… or a surface enough like one to make no difference. The cool, steady stars of space burned above her. She sat up and rubbed her sticky eyes.

I feel awful, she thought. I want a bath, I want breakfast, I want to brush my teeth! But baths and toothbrushes and any food but bologna sandwiches with mustard were all a long way away.

She dropped her hands into her lap, feeling slow and helpless, and looked about her. A sense of shock grew in her: all around, in what had been the absolutely smooth surface of the planet, there were great cracked holes, as if the place had had a sudden meteor shower while she was asleep. But the debris lying around wasn't the kind left by meteor strikes. "Sheesh," she muttered.

Something poked her from behind.

Dairine screamed and flung herself around. She found herself staring at the small, turtlelike glassy creature that had been the last straw the night before. It had walked into her, and was continuing to do so, its short jointed legs working busily though it was getting nowhere: like a windup toy mindlessly walking against a wall. "With," it said.

"Oh, heck," Dairine said in relief. She sagged with embarrassment. Two days ago she would have thought scorn to scream because of anything, up to and including Darth Vader himself. . but the world looked a little different today.

She grabbed the steadily pedaling little thing and held it away from her to look at it. It was all made of the same silicon as the surface; the inside of its turtlish body was a complex of horizontal layers, the thickest of them about half an inch across, the thinnest visible only as tiny colored lines no thicker than a hair. . thousands of them packed together, at times, in delicate bandings that blended into one subtle color. Dairine knew she was looking at a chip or board more complex than anything dreamed of on Earth. She could see nothing identifiable as a sensor, but it had certainly found her right away last night: so it could see. She wondered if it could hear.

"Well, how about it, small stuff?" she said. It was rather cute, after all. "Say hi."

"Hi," it said.

She put her eyebrows up, and looked over her shoulder at the computer, which was sitting where she had left it the night before. "Did you teach this guy to talk?"

"There is very little I did not teach the mind that made them," said the computer calmly.

Dairine looked around at the many, many jagged holes in the surface. "I bet. Where are they all?"

"Indeterminate. Each one began walking around the surface in a random fashion as soon as it was produced."

"Except for this one," Dairine said, and lifted the creature into her lap. It was surprisingly light. Once there, the creature stopped trying to walk, and just rested across her knees like a teatray with a domed cover on it. "Good baby," Dairine said. She touched one of the legs carefully, maneuvering the top joint gently to see how it worked. There were three joints: one ball-and-socketlike joint where it met the body, and two more spaced evenly down the leg, which was about six inches long. The legs were of the same stuff as the outer shell of the body dome: translucent, like cloudy glass, with delicate hints of color here and there. "Why didn't you go walking off with everybody else, huh?" she said as she picked it up to flip it over and examine its underside.

Its legs kicked vigorously in the air. "With," it said.

Dairine put the creature down, where it immediately walked into her again and kept walking, its legs slipping on the smooth surface.

"With, huh. Okay, okay, 'with' already." She picked it up again and put it in her lap. It stopped kicking.

She glanced up at the sky. The galaxy was rising again. For a few seconds she just held still, watching the curving fire of it. "How long is the day here?" she said.

"Seventeen hours," said the computer.

"Fast for such a big planet," she said. "Mostly light elements, though. I guess it works. How long was I asleep?"

"Fourteen hours."

Dairine made an annoyed face. There went that much of her research time. She felt fairly certain that if the BEMs didn't catch up with her shortly, someOne else would. She didn't like the thought. "I've got to get some work done," she said, and glanced down at the turtly, glassy creature in her lap. "What about you? You can't sit here all day. Neither can I."

"Hi," said the glass turtle.

She had to laugh. "Are you still talking to"-she didn't know what to call it: she patted the glassy ground-"our friend here?"

"Yes," the computer said. "Response is slow. It is still assimilating and coordinating the data."

"Still?" Dairine let out a breath. If there was so much information in the manual functions that a computer with this much memory was still sorting it, what hope did she have of finding the information she needed in time to be able to do anything useful to the Lone One with it? She was going to have to help it along somehow. "Can you ask it to call back this little guy's friends? I want to look at them."

"Working."

Dairine stretched and considered that the next time she went out to space, she was going to plan things a little more carefully. Or stay at a hotel. Where, for example, was she going to find something to drink?

She hadn't squirreled anything away in her claudication: she was going to have to find water. More to the point, there were no bathrooms here. Dairine wished heartily that she had taken time in the Crossings, or even back at Natural History, to use the facilities for something other than programming interstellar jumps. The memory of what sometimes seemed to be her mother's favorite line, "You should have gone before we left!" made her grin ruefully.

She got up to improvise what she could. Her turtle started to go with her. "No," she said, as she might have to Ponch. "Stay!" The turtle's response to this was the same as Ponch's would have been: It went after her anyway.

Dairine sighed and headed off to a little outcropping of rock about half a mile away. When she had finished, and started back to where the computer lay, she could already see small shapes moving on the horizon. She sat down with her bread and bologna, started making a sandwich, and waited for them.

Pretty soon she was knee-deep in turtles, or would have been had she been standing up. After the first few walked into her as her lapturtle had, she asked the computer to get them to hold still when they reached her. Something like two hundred of them were shortly gathered around her. They were all exact copies of her friend, even to the striations and banding inside them. She sighed a little as she looked at them.

"This isn't gonna work, you guys," she said. "There's more to life than walking around, and none of you have anything like hands…"

"Hi!" said all the turtles, simultaneously. She couldn't hear the ones that were outside her bubble of air, but the ones that were inside made racket enough.

She had to laugh at that. "Look," she said to the computer, pushing her first turtle out of her lap and putting the computer there instead, "where did the mind behind these critters get the design for them?"

"Probably from one of the design templates in the "Make" utility," said the computer.

"Okay, let's get into that. If these guys are going to be the arms and legs for the mind that's running them, they need arms!"

The computer's screen flicked obediently to the opening screen for the "Make" utility. Dairine frowned at the menu for a while. The computer had a machine-assisted drafting utility: she chose that, while her turtle tried to climb back into her lap.

"No," she said. "No, honey!" ' It was no use. "With!" said the turtle. "With, with, with, with-"

She laughed helplessly. "Boy, are you ever GIGO," she said.

"Yes," the turtle said, and sat down next to her abruptly, folding all its legs under it like a contented mechanical cat.

Dairine put her eyebrows up at that. Was that all it wanted? A name? "Gigo," she said, experimentally.

"Yes!"

It sounds happy, she thought. Can it have emotions?

"Good baby," she said, and patted it. "Good Gigo."

"Yes!" said Gigo, and "Yes!" said several of the other turtles around, and it began to spread through the crowd to the limits of her air: "Yes, yes, yes-"

"Okay," she said, "he's good, you're all good, now put a cork in it!"

They fell silent. But there had been no mistaking the sound of joy.

"I can see I'm gonna have to find names for all of you," she said. "Can't have the whole bunch of you answering to that."

She turned her attention to the blank graphics screen. "Bring up the design that. ." She paused. "I can't just keep banging on the ground. Does what you were talking to have a name for itself?"

"No."

Dairine sighed. "Okay, just let's call it a motherboard for the moment. Bring up the design it was using for Gigo and his buddies."

The screen flickered, showing Dairine a three-dimensional diagram, which the computer then rotated to show all the turtle's surfaces. "Good," she said. "How do I make changes?"

"The screen is touch-sensitive. Touch a line and state what you want done with it."

Dairine spent a cheerful hour or so there, pausing for bites of sandwich, as she started to redesign the turtles. She wasn't shy about it. The original design had its points, but as the mobile units of an intelligence, the turtles were sadly lacking in necessary equipment. She built several of the legs into arms, with six claws apiece at the end of them, four "fingers" and two opposable "thumbs"; this hand she attached to the arm by a ball-and-socket joint so that it could rotate completely around without having to stop. As an afterthought, she put another pair of arms on the turtle's back end, so that it wouldn't have to turn around to pick something up if it didn't want to.

She took the turtle's rather simplistic visual sensor, barely more than a photosensitive spot, and turned it into something of a cross between the human retina and a bee's faceted eye-a multiple-lensed business equally good for close work and distant vision. She placed several of these around the turtle's perimeter, and a couple on top, and then for good measure added a special-purpose lens that was actually something like a small Cassegrain telescope, focusing on a mirror-polished bit of silicon buried a ways into the turtle's "brain." She added infrared and ultraviolet sensing. Ears for sound they already had; she considered that it might be wise to give them something to hear radio with, too, but couldn't decide on which frequency to work with, and let the idea go for the moment. They could work it out themselves.

Dairine sat staring at the screen, musing. The newly awakened intelligence had made all its mobiles alike: probably because it didn't understand the concept of otherness yet. She would make them different from one another. But they were going to have to be different on the inside, too, to do any good. If some danger comes along that they have to cope with, it's no use their information processors being all the same: whatever it is could wipe them all out at once. If they're as different as they can be, they'll have a better chance of surviving.

She paused in her design to look closely at the structure of the chip layering in the turtles-not so much at what the layers were made of, but what their arrangement meant. At the molecular level she found the basic building-block of the chips, as basic as DNA in humans: not a chain molecule, but a sort of tridimensional snowflake of silicon atoms and atoms of other elements. DNA was simple beside these.

Any given silicon molecule hooked with up to fourteen others, using any one of fifty different chemical compounds to do it; and every different arrangement of hookups between molecules or layers had a specific meaning, as each arrangement has in DNA. With the help of the computer she began to sort out the code buried in the interconnected snowflakes. Hours, it took her, and she was perfectly aware that even with the computer's help she couldn't hope to deal with more than the tip of this iceberg of information. Some parts of the chip structure she did manage to identify as pure data storage, others as sensor array, associative network, life support, energy management.

Dairine began devising layering arrangements different from those in the turtles. She designed creatures that would have more associative network and so could specialize in problem solving: others with more data stacks, turtles that would be good at remembering; mobiles more richly endowed with sensors, and senses, than some of the others, that would see and hear and feel most acutely. One arrangement of layers, the one that the computer identified for her as the seat of the turtles' emotions, seemed an awfully tiny thing to Dairine. She expanded it to about three times its original size, and allowed it to interconnect at will with the other associative areas, with data memory and with the senses. Finally, to every model she designed, Dairine added a great deal of latent memory area, so that each mobile would have plenty of room to store what it experienced and to process the data it accumulated.

Having done all these things, she went back to her original design and copied it several times, making a number of different "models": a large, strong one for heavy work; a small one with extra hands in various sizes, from human-hand size to tiny claws that could have done microsurgery or precision work almost on the molecular level. And she added the necessary extra sensor arrays or materials reinforcement that these changes would need to support them.

She sat back and sighed then, and unfolded her cramped legs, and reached down for her sandwich, which had gone stale on top while she worked. "Okay," she said to the computer. "Ask the motherboard to run off a few of those and let's see what happens."

"Considerable reprogramming will be necessary," said the computer.

"I know," said Dairine, between bites of the sandwich, making a face at the taste of it. "I'm in no rush."

The computer's screen filled with binary as it began conferring with the motherboard in machine language. What do I mean I'm in no rush? Dairine thought, momentarily distracted while Gigo climbed into her lap again. "Did you finish that analysis run about the Lone One for me?"

"Yes," said the computer. "Do you want it displayed?"

"Yeah, please."

The binary went away from the screen, replaced by print. Dairine didn't look at it immediately. She leaned back and gazed up. The galaxy was all set but for one arm, trailing up over the far, far horizon, a hook of light. The dull red sun Svas following it down as if attached to the hook by an invisible string. An old, old star, Dairine thought. Not even main-sequence anymore. This could have been one of the first stars created in this universe. . Might have been, considering how far out this galaxy- The thought was shocked out of her.

Something other than her voice was making a sound. It was a rumbling, very low, a vibration in the surface she sat on. "What the- You feel that?" she said to the computer.

"Vibration of seismic origin," the computer said. "Intensity 2.2 Richter and increasing."

There was precious little on the planet's surface to shake. Dairine stood up, alarmed, and watched the turtles. For all their legs, they were having trouble keeping their footing on the slick surface. Gigo hooked a leg around Dairine's and steadied itself that way. "Is this gonna get worse?" Dairine said.

"Uncertain. No curve yet. Richter 3.2 and increasing. Some volcanic eruption occurring in planet's starward hemisphere."

Got to do something about their leg design if this happens a lot, Dairine thought-and then was distracted again, because something was happening to the light: It wavered oddly, dimming from the clear rose that had flooded the plain to a dark dry color like blood. She stared upward.

The sun was twisting out of shape. There was no other way to describe it. Part of its upper right-hand quarter seemed pinched on itself, warped like a round piece of paper being curled. Prominences stretched peculiarly, snapped back to tininess again: the warping worsened, until the star that had been normal and round was squeezed small, as if in a cruel fist, to a horizontal, fluctuating oval, then to a sort of tortured heart-shape, then to an oval bent the other way, leftward. Sunspots stretched like pulled taffy, oozed back to shape again, and the red light wavered and shifted like that of a candle about to be blown out in the wind.

Dairine stood with a terrible sickness at the heart of her, for this was no kind of eclipse or other astronomical event that she had ever heard of. It was as if she was seeing the laws of nature broken in front of her.

"What is that?" she whispered.

"Transit of systemic object across primary," said the computer. "The transiting object is a micro black hole."

Dairine sat down again, feeling the rumbling beneath her start to die away. The computer had mentioned the presence of that black hole earlier, but in the excitement she had forgotten it. "Plot me that thing's orbit," she said. "Is that going to happen every day?"

"Indeterminate. Working."

"I don't like that," said Gigo with sudden clarity.

Dairine looked over at it with surprise and pulled it into her lap. "You're not alone, small stuff," she said.

"It gives me the shakes too." She sat there for a second, noticing that she was sweating. "You're getting smart, huh?" she said. "Your mom down there is beginning to sort out the words?"

"It hurts," said Gigo, sounding a little mournful.

"Hurts. ." Dairine wasn't sure whether this was a general statement or an answer to her question.

Though it could be both. A black hole in orbit in the star system would produce stresses in a planet's fabric that the planet-if it were alive, like this one-could certainly feel. Line the black hole up with its star, as it would be lined up in transit, and the tidal stresses would be that much worse. What better cause to learn to tell another person that something was hurting you?. . Now that there was another person to tell.

Dairine patted Gigo absently. "It's all over, Gigo," she said.

"Gigo, yes."

She grinned faintly. "You really like having a name, huh?"

"A program must be given a name to be saved," Gigo said quite clearly, as if reciting from memory-but there was also slight fear in its voice, and great relief.

"Well, it's all over," Dairine said. . while surreptitiously checking the sky to make sure. Tiny though it was-too small to see-a micro black hole was massive enough to bend light toward it. That was what had made the sun look so strange, as the gravity center of the black hole's field bent the round image of the sun forward onto itself. The realization made Dairine feel a lot better, but she didn't particularly want to see the sun do that again. She turned back to the computer. "Let's get back to work."

"Which display first," the computer said, "the black hole's orbit or the research run on the Lone Power?"

"The orbit."

It drew it for her on the screen, a slowly moving graphic that made Dairine's insides crawl. The black hole's orbit around its primary was irregular. These transits occurred in twenty out of every thirty orbits, and in the middle five orbits the hole swung much closer to the planet and appeared to center more closely on the sun. This last one had been a grazing transit: the micro hole had only passed across the upper limb of the star. Dairine did not want to see what a dead-center transit would look like, not at all.

But in the midst of her discomfort, she still found a little room to be fascinated. Apparently the black hole was the cause of the planet's many volcanoes: the tidal stresses it produced brought up molten silicon, which erupted and spread over the surface. Without the frequent passages of the hole near the planet, the millions of layers of the motherboard would never have been laid down, and it would never have reached the critical "synapse" number necessary for it to come alive. .

"Okay," she said. "Give me the research run, and let me know when the motherboard's ready to make some more of these guys."

"Working." V

Dairine began to read, hardly aware of it when Gigo sneaked into her lap again and stared curiously at the screen. She paged past Nita's and Kit's last run-in with the Lone Power and started skimming the precis before it for common factors. Odd tales from a hundred planets flicked past her, and sweat slowly began to break out on Dairine as she realized she could not see any common factors at all. She could see no pattern in what made the Lone

Power pick a specific world or group or person to attack, and no sure pattern or method for dealing with It. Some people seemed to beat the Lone One off by sheer luck. Some did nothing that she could see, and yet ruined Its plans utterly. One wizard on a planet of Altair had changed the whole course of his world's history by inviting a person he knew to be inhabited by the Lone One to dinner. . and the next day, the Altairans' problem (which Dairine also did not understand except that it had something to do with the texture of their fur) simply began to clear up, apparently by itself.

"Maybe I should buy It a hot dog," Dairine muttered. That would make as much sense as most of these solutions. She was getting a feeling that there was something important about dealing with the Lone Power that the computer wasn't telling her.

She scrolled back to Nita and Kit's precis again and read it through carefully, comparing it with what she had seen them do or heard them say herself. Her conversation with Nita after she had seen her sister change back from being a whale was described in the precis as "penultimate clarification and choice."

Dairine scowled. What had Nita chosen? And why? She wished she had her there to ask her. . but no.

Dairine didn't think she could cope with Nita at the moment. Her sister would certainly rip into her for doing dumb things, and Dairine wasn't in the mood. . considering how many dumb things she had done in the past day and a half.

Still, Dairine thought, a little advice would come in real useful around now. .

"Ready," said the computer suddenly.

"Okay. Ask it to go ahead."

"Warning," the computer said. "The spell being used requires major restructuring of the substrate.

Surface stability will be subject to change without notice."

"You mean I should stand back?"

"I thought that was what I said," said the computer.

Dairine made a wry face, then picked it up and started walking. "C'mon, Gigo, all you guys," she said.

"Let's get out of the way."

They trooped off obediently after her. Finally, about a quarter-mile away, she stopped. "This far enough away, you think?" she said to the computer.

"Yes. Working now."

She felt a rumbling under the surface again, but this was less alarming than that caused by the transit of the black hole-a more controlled and purposeful sound. The ground where Dairine had been sitting abruptly sank in on itself, swallowing the debris caused by the breaking-out of the turtles. Then slow ripples began to travel across the surface, as it turned itself into what looked like a bubbling pot of syrup, clear in places, swirled and streaked with color in others. Heat didn't seem to be involved in the process. Dairine sat down to watch, fascinated.

"Unnamed," Gigo said next to her, "data transfer?"

Dairine looked down at the little creature. "You want to ask me a question? Sure. And I have a name, it's Dairine."

"Dairrn," it said. She chuckled a little. Dairine had never been terribly fond of her name-people tended to stumble over it. But she rather liked the way Gigo said it. "Close enough," she said. "What's up?"

"Why do you transfer data so slowly?"

That surprised her for a moment, until she considered the rate at which the computer and the motherboard had been talking: and this was in fact the motherboard she was talking to now. To something that had been taught to reckon its time in milliseconds, conversation with her must seem about as fast as watching a tree grow. "For my kind of life, I'm pretty quick," Dairine said. "It just looks slow to you."

"There is more-slowlife?"

"Lots more. In fact, you and the Apple there are about the only, uh, 'quicklife' there is, as far as I know."

She paused and said, "Quick life, as opposed to dumb machines that are fast, but not alive."

"I see it, in the data the Lightbringer gave us," said Gigo. Dairine glanced over at the computer. "Data transfer?"

"Sure," Dairine said.

"What is the purpose of this new program run?"

Wow, its syntax is really shaping up. If this keeps up, it's gonna be smarter than me!… Is that a good idea? But Dairine laughed at it. It was the best idea: a supercomputer faster than a Cray, with more data in it than all the New York Public Library-what a friend to have! "When I'm gone," Dairine said, "you're going to need to be able to make your own changes in your world. So I'm making you mobiles that will be able to make the changes."

"Data transfer! Define 'gone'!"

Gigo's urgency surprised Dairine. "I can't stay here," she said. No, better simplify. "My physical presence here must terminate soon," she said. "But don't worry. You guys won't be alone."

"We will!" cried Gigo, and the whole planet through him.

"No, you won't," Dairine said. "Don't panic. Look, I'm taking care of it. You saw all the different bodies I wrote into the 'Make' program for you? You saw how they're all structured differently on the inside?

That's so they can have different personalities. There'll be lots more of you."

"How?"

Dairine hoped she could explain this properly. "You'll split yourself up," she said. "You'll copy your basic programming in a condensed form into each one of them, and then run them all separately."

There was a long, long silence. "Illegal function call," said Gigo slowly.

"It's not. Believe me. It sounds like it, but it works just fine for all the slowlife. . it'll work for you too.

Besides," Dairine said, "if you don't split yourself up, you won't have anybody to talk to, and play with!"

"Illegal function call. ."

"Trust me," Dairine said, "you've got to trust me. . Oh, look at that."

The surface, which had been seething and rippling, had steadied down, slick and glassy again. Now it was bulging up, as it had before. There was no sound, but through each hunching, each cracking hummock, glassy shapes pushed themselves upward, shook the fragments off, stood upright, walked, uncertain and ungainly as new foals. In the rose light of the declining sun they shone and glowed; some of them tall and stalky, some short and squat, some long and flowing and many-jointed, some rounded and bulky and strong; and one and all as they finished being made, they strode or stalked or glided over to where Dairine was. She and Gigo and the first turtles were surrounded by tens and twenties and hundreds of bright glassy shapes, a forest of flexing arms, glittering sensors, color in bold bands and delicate brushings-grace built in glass and gorgeously alive. "Look at them," Dairine said, half lost in wonder herself. "It'll be like being you. . but a hundred times, a thousand times. Remember how the light looked the first time?"

"Data reacquired," Gigo said, soft-voiced.

"Like that," Dairine said. "But again and again and again. A thousand of you to share every memory with, and each one able to see it differently. . and everyone else'll see it better when the one who sees it differently tells all the others about it. You won't be the only quicklife anymore. Copy your programming out, and there'll be as many of you as you want to make. A thousand of you, a million of you to have the magic together. . "

"The call is legal," Gigo said after a moment. "Data transfer?"

"What?"

"Will there be pain? Like the Dark that Pulls?"

Dairine's heart wrenched. She picked Gigo up and pulled him into her lap. "I don't know, small stuff," she said. "There might be. I'm here if it does. You just hold on to me, and don't be scared."

She turned to the computer. "You know how to describe this to the motherboard?" she said. "They've all got to have all the major programming you gave their mom, but you're gonna have to pack the code down awful tight. And make sure they still don't lose the connection to her once they're autonomous."

"Noted," said the computer. "Override protocols require that I confirm with you what parts of the wizardly programming are to be passed on to each individual, and to what number of individuals."

She looked at it in surprise. "All of it, of course. And all of them."

"Reconfirmation, please. This far exceeds the median distribution and percentage."

"Oh? What is it on Earth?"

"Ratio of potential wizards to nonpotential: one to three. Ratio of practicing wizards to potential wizards: one to one hundred. Ratio of-"

"Are you trying to tell me that there are sixteen million practicing wizards on Earth?"

"Sixteen million, four hundred and-"

Dairine paused to consider the condition the world was in. "Well, it's not anywhere near enough! Make them all wizards. Yes, I confirm it three times, just get on with it, these guys are getting twitchy." And indeed Gigo was trembling in her lap, which so astonished Dairine that she cuddled him close and put her chin down on the top of him.

Instantly all his legs jerked spasmodically. Dairine held on to him, held on to all of them through him.

Maybe some ghost of that first physical-contact link was still in place, for she went briefly blind with sensations that had nothing to do with merely human sensoria. To have all one's life and knowledge, however brief, ruthlessly crushed down into a tiny packet, with no way to be sure if the parts you cherished the most would be safe, or would be the same afterward-and then to multiply that packet a thousand times over, till it pushed your own thoughts screaming into the background, and your own voice cried' out at you in terror a thousand times, inescapable-and then, worst of all, the silence that follows, echoing, as all the memories drain away into containers that may or may not hold them- Dairine was in the midst of it, felt the fear for all of them, and had nothing to use against it but the knowledge that it would be all right, could be all right. She hung on to that as she hung on to Gigo through his frenzied kicking, her eyes squeezed shut, all her muscles clenched tight against the terror in her arms and the terror in her heart. .

Silence, silence again, at last. She dared to open her eyes, lifted her head a little to look around her.

Gigo was still. The glittering ranks around her shifted a little-a motion here, a motion there, as if a wind went through glass trees at sunset. The light faded, slipped away, except for the chill gleam of the bright stars over everything: the sun had set.

"It hurt," Gigo said.

He moved. Dairine let him clamber down out of her lap.

He turned and looked at her. "It hurt," he said.

"But it was worth it," said one of the taller mobiles, one of the heavy-labor types, in a different voice.

The voices began to proliferate. Motion spread farther through the crowd. Mobiles turned and spoke to one another in a chorus of voices like tentative synthesizers, changing pitch and tone as if looking for the right ones. Outside the area where there was air, communication passed by less obvious means. Dairine sat in the midst of it, heard words spoken with the delight of people tasting a new food for the first time, heard long strings of binary recited as if the numbers were prayers or poems, saw movement that even to a human eye was plainly dance, being invented there in front of her. She grinned like a loon. "Nice job," she said to the Apple.

"Thank you."

"We did good, huh?"

"Indeterminate," said the computer.

Dairine shrugged and got up to wander among the mobiles and get a closer look at them. They clustered around her as she went, touching her, peering at her, speaking to her again and again, as if to make sure they really could.

The cacophony of voices delighted her, especially since so many of them said the same thing to her at first: "Save, please!" She knew what they wanted, now, and so she named them. She started out with programmers' puns, and shortly the glassy plain was littered with people named Bit and Buffer, Pinout and Ascii, Peek and Poke, Random, Cursor, String, Loop, Strikeout, Hex, and anything else she could think of. But she ran out of these long before she ran out of mobiles, and shortly the computer types were joined by Toms, Dicks and Harrys, not to mention Georges, Roberts, Richards, Carolyns, and any other name she could think of. One group wound up named after her entire gym class, and another after all her favorite teachers. Dairine ran through comic-book heroes, numerous Saturday morning cartoon characters, the bridge crew of the Starship Enterprise, every character named in The Lord of the Rings and the Star Wars movies (though she did not name any of them "Darth Vader"), the names and capitals of all fifty states, all the presidents, and all the kings and queens of England she could think of. By the time she was finished, she wished she had had a phone book. She was hungry and thirsty, but satisfied to think that somewhere in the universe, a thousand years from now, there would be a world that contained both Elizabeth the First and Luke Skywalker.

She finally flopped down and started to make another sandwich. During the naming, Gigo had followed her through the crowd. Now he sat beside her, looking with interest at the sandwich. "What's that?" he said.

Dairine opened the mustard jar, made a resigned face, and dug a finger in. "It's going to be food," she said. "You have that in your memory."

"Yes." Gigo was quiet for a moment. "From this one acquires energy."

"Yup." Dairine took the last few slices of bologna out of the package, looked at them regretfully, and put them on the bread.

Various others of the mobiles were drifting in to stand or crouch or sit around where Dairine was.

"Dairine," said Gigo, "why is this necessary for you?"

She shrugged. "That's the way people are built. We get tired, get hungry… we have to refuel sometimes.

You guys do it, though you do it through contact with the motherboard: I had the computer build in the same kind of wizardry-managed energy transfer it used to get in touch with your mom in the first place.

There's loads of geothermic. It'll be ages before you run down."

She munched on the sandwich. One of the tall, leggy mobiles, a storkish one that she remembered naming Beanpole, said, "Why should we run down?"

She glanced up at that, between bites. Another of the mobiles, one of the first ones she had named, a stocky one called Monitor, said, "There is something wrong with the energy in this universe."

"dS = dQ/T," said a third, one of the original turtles, named Logo.

Dairine began to feel uneasy. That was indeed the equation that expressed entropy, the tendency of any system to lose its energy into the void. "It's not that anything's wrong," she said. "That's just the way things are."

"It is poor design," Beanpole said.

"Uh, well," Dairine said. This was something that had occurred to her on occasion, and none of the explanations she had heard had ever satisfied her. "It's a little late to do anything about it."

"Is it?" said Gigo.

Dairine stared at him.

"Things shouldn't run down," Monitor said. "Something should be done about it."

"What if you run down some day?" said Beanpole, sounding stricken.

"Uh," Dairine said. "Guys, I will, eventually. I'm part of this universe, after all."

"We won't let you run down," said Monitor, and patted her arm timidly.

"We have to do something about this," Logo said.

That was when the conversation began to get complex. More and more of the mobiles drifted into it, until Dairine was surrounded by a crowd of the robots she had built the most dataprocessing ability into.

Phrases like quasi-static transitions and deformation coordinates and the zeroth law and diathermic equilibrium flew around until Dairine, for all her reading, was completely lost. She knew generally that they were talking about the laws of thermodynamics, but unless she was much mistaken, they were talking about them not so much as equations but as programs. As if they were something that could be rewritten…

But they can be, she thought suddenly, with astonishment. The computer's "Manual" functions dealt with many natural laws that way. Wizards knew the whole of the nature and content of a physical law. Able to name one completely, a wizard can control it, restructuring it slightly and tempo rarily. But the restructuring that the mobiles were discussing wasn't temp rary. .

"Listen, guys," she said, and silence fell abruptly as they turned to he "You can't do this."

"Of course we can," Logo said.

"I mean, you shouldn't."

"Why?"

That stopped her for a second. It seemed so obvious. Stop entropy, and the flow of time stopped. And where was life then? But it occurred to Dairine that in everything she'd read in the manual, either in Nita's version of it or on the computer, it never said anywhere that you should or shouldn't do something. It might make recommendations, or state dangers. . but never more than that. Choice was always up to the wizard. In fact, there had been one line that had said, "Wizardry is choice. All else is mere mechanics.

. ."

"Because," she said, "you'll sabotage yourselves. You need entropy to live. Without it, time can't pass.

You'll be frozen, unable to think. And besides, you wouldn't want to live forever. . not even if you could really live without entropy. You'd get bored. . "

But it sounded so lame, even as she said it. Why shouldn't one live forever? And the manual itself made it plain that until the Lone Power had invented death, the other Powers had been planning a universe that ran on some other principle of energy management. . something indescribable. But the Lone One's plans messed Theirs up, and ruined Their creation, and the Powers had cast it out. What would be wrong with starting from scratch?. .

Dairine shook her head. What's the matter with me? What would that do to the universe we have now?

Crazy! "And there are other sentient beings," she said. "A lot of them. Take away entropy and you freeze them in place forever. They wouldn't be able to age, or live…"

"But they're just slowlife," Logo said. "They're hardly even life at all!"

"I'm slowlife!" Dairine said, annoyed.

"Yes, well, you made us," said Beanpole, and patted her again. "We wouldn't let anything bad happen to you."

"We can put your consciousness in an envelope like ours," said Logo. "And then you won't be slowlife anymore."

Dairine sat astonished.

"What do the equations indicate as the estimated life of this universe at present?" said Monitor.

"Two point six times ten to the sixtieth milliseconds."

"Well," Logo said, "using an isothermal reversible transition, and releasing entropy-freeze for a thousand milliseconds every virtual ten-to-the-twelfth milliseconds or so, we could extend that to nearly a hundred thousand times its length. . until we find some way to do without entropy altogether. . "

They're talking about shutting the universe down for a thousand years at a time and letting it have a second's growth every now and then in between! "Listen," Dairine said, "has it occurred to you that maybe I don't want to be in an envelope? I like being the way I am!"

Now it was their turn to look at her astonished.

"And so do all the other kinds of slowlife!" she said. "That's the real reason you can't do it. They have a right to live their own way, just as you do!"

"We are living our own way," said Logo.

"Not if you interfere with all the rest of the life in the universe, you're not! That's not the way I built you."

Dairine grasped at a straw. "You all had that Oath first, just the same as I did. To preserve life. .' "

"The one who took that Oath for us," said Logo, "did not understand it: and we weren't separately conscious then. It wasn't our choice. It isn't binding on us."

Dairine went cold.

"Yes, it is," Gigo said unexpectedly, from beside her. "That consciousness is still part of us. / hold by it."

"That's my boy," Dairine said under her breath.

"Why should we not interfere?" Logo said. "You interfered with us."

There was a rustle of agreement among some of the mobiles. "Not the same way," Dairine said. . and again it sounded lame. Usually Dairine got her way in an argument by fast talk and getting people emotionally mixed up… but that was not going to work with this lot, especially since they knew her from the inside out. "I found the life in you, and let it out."

"So we will for the other fastlife," said Logo. "The 'dumb machines' that your data showed us. We will set them free of the slowlife that enslaves them. We will even set the slowlife free eventually, since it would please you. Meantime, we will 'preserve' the slowlife, as you say. We will hold it all in stasis until we find a way to free them from entropy. . and let them out when the universe is ready."

When we are ready, Dairine knew what Logo meant, and she had a distressing feeling that would be never.

"It's all for your people's own sake," said Logo.

"It's not," said Gigo. "Dairine says not, and I say not. Her kind of life is life too. We should listen to the one who freed us, who knows the magic and has been here longest, is wisest of any of us! We should do what she says!"

A soft current of agreement went through others of the many who stood around. By now, every mobile made since she had come here was gathered there, and they all looked at Dairine and Gigo and Logo, and waited.

"This will be an interesting argument," Logo said softly.

Dairine broke out in a sudden cold sweat that had nothing to do with the temperature. "Listen," she said to the Apple, "how long have I been on this planet now?"

"Thirty-six hours," it said.

She turned slowly to look at Logo. It said nothing. It did not need to: no words could have heightened Dairine's terror. She had been expecting frightful power, a form dark and awful, thunder and black lightning. Here, blind, small, seemingly harmless, the mobile stood calmly under her gaze. And Dairine shook, realizing that her spell had worked. She had had a day and a half to find a weapon-time that was now all gone. She had found the weapon-but she had given it a mind of its own, and made it, or them, useless for her defense. She now had a chance to do something important, something that mattered-mattered more than anything-and had no idea how.

"A very interesting argument," said the Lone Power, through Logo's soft voice. "And depending on whether you win it or not, you will either die of it, or be worse than dead. Most amusing."

Dairine was frozen, her heart thundering. But she made herself relax, and sit up straight; rested her elbows casually on her knees, and looked down her nose at the small rounded shape from which the starlight glinted. "Yeah," she said, "well, you're a barrel of laughs, too, so we're even. If we're going to decide the fate of the known universe, let's get started. I haven't got all day."
