When necessary, all of the major systems of the Sirian Pearl could be driven by the agile thought of one skilled pilot working alone. But the ship served its human masters most precisely and reliably when it was operated by a crew of six, who could divide its several functions efficiently among them. The five crew stations other than the pilot's, all separated in different parts of the ship, were now filled with Domingo's friends and fellow colonists. He congratulated himself, as the voyage of the relief force got under way, that days ago, even with wedding preparations and mayoral duties competing for his attention, he had made himself take time over the final selection of the crew for his new ship and for a couple of test-and-training flights.
Domingo himself now held the helm. He was sitting in his armored chamber near the center of the ship, still wearing some of the good clothes he had put on for his daughter's wedding. On his forehead rested the spacecraft commander's mindlink control band; it was a physically light weight, but he well knew that it could be as heavy as any crown.
Without moving a finger or even blinking an eyelid, the captain personally held the Pearl on what he considered her best course for Liaoning—close to, but not identical with, the best course as simultaneously calculated by the ship's computer. He still considered the human brain, particularly his own, superior to hardware at the most difficult parts of the incredibly complex task. There was some feedback from the equipment to the optic centers of the brain, making the control a partly visual process, trickily akin to imagination—inexperienced pilots often got into trouble imagining that there was no difference.
The autopilot, teamed with the ship's computer, might have managed to conduct the flight just as well—or almost as well—as he could, but right now the captain preferred to drive his new ship himself. The Pearl boasted new engines and improved protective fields—at this speed inside the nebula you needed protection against collisions with mere molecules, there were so many of them. Domingo might have raced well ahead of the five other ships in his small squadron, but he did not. Urgent as was the need for speed, he calculated that it was a still more urgent need that his force stay together in the face of a certainly formidable and possibly superior enemy.
Leviathan. The captain had a personal score to settle with that particular legendary foe—whether or not it made sense to feel a personal enmity toward a machine. But he couldn't be certain that he was going to encounter Leviathan this time. All he could really be sure of was that he was leading his people against berserkers.
The berserkers were robotic relics of some interstellar war that had been fought long before the beginning of written history on Earth. They were, in their prime form, vast inanimate spacegoing fortresses, moving lifelessly across the Galaxy in obedience to their fundamental programming command that all the life they could find must be destroyed. In all the centuries of expansion of Earth-descended humanity among the stars, berserkers were by far the greatest peril that they had encountered.
Still without stirring himself physically, Domingo could have called up on any of several screens or stages the image of whitespace whipping by outside. But after making the checklist test of that function shortly after launching, he forbore to use it. Instead, during the first hour of the flight, Domingo called up human faces, those of his fellow colonists aboard the other ships, coming and going on his screens and stages. In this way he held conversation fairly steadily with the other units of the relief squadron. There were five other ships in all, including the craft commanded by Gujar Sidoruk, and Niles Domingo, as commander of the relief force, wanted to make sure that when the combat zone was reached they would all continue to follow his orders.
That willingness established to his satisfaction, as well as it could be before the fact, he ordered intership conversation to be broken off and imposed complete radio silence.
Desultory intercom conversation continued aboard the Sirian Pearl. There was no reason why it should not.
Some of the crew, talking now among themselves, expressed concern for people they knew on Liaoning, and speculated on the strength of the berserker force attacking there. It was possible that the report of only one berserker was outdated, that more attackers had come in later, after the courier was sent. If the enemy force at the scene proved to be overwhelming, the relief squadron would have to turn and run for home again—if it was still able to do even that much. Everyone understood that, but no one mentioned it.
Domingo took little part in the rambling intercom chatter, but he listened to it with more than half an ear even while his mind went its own way, watching the instruments before him and trying to make plans. As it was with the captains of the other ships, so it was even with his own crew: He knew some of them better than he knew others. The population of Shubra was small, but it was far from stable. People moved on- and offworld frequently. Some of the present population were almost strangers to the mayor. Some were combat veterans and some were not. Domingo, who certainly had earned that status, wanted to monitor the nerve, and assess the probable behavior under pressure, of those who had not.
It would have been an excellent thing, of course, to have the Pearl manned by an all-veteran, picked crew; but in this militia organization, rank had no such privilege. The available pool of experience had to be shared out among all the crews.
The veterans on the Pearl, besides Domingo himself, included Iskander Baza, Wilma Chanar and Henric Poinsot. That left two rookies on the team.
Apollina Suslova had not been many months on Shubra and was really still a citizen of Yirrkala. On being assigned to Domingo's crew—every capable adult had an alert station somewhere—she had told him that she had been briefly under bombardment at least once, on yet another colony, but she had never known the strain of helping to control a ship in battle.
Domingo suspected she was becoming attracted to him, and he found the idea not displeasing. If it should turn out that way, though, he'd have to get her off his combat crew. In his experience the two kinds of relationship didn't mix. A married couple aboard ought to be different. He hoped so, at least. Not that he himself had any intention of getting married again.
Simeon Chakuchin, unlike his wife Wilma Chanar, was a comparatively new settler, but all indications were that he was psychologically strong and capable. Not everybody who reached the frontier colonies fit those criteria, though you'd think they might.
The captain's meditations were interrupted by the voice of Iskander Baza on intercom: "I've got Liaoning on the detectors, Cap. Still at extreme range."
The captain switched one of his own display stages to take the forward detectors' signal. Even to his trained perception, the solid-looking image was no more than a vague mottled blur. The planetoid that was the destination of the relief force was in an orbit not greatly different from Shubra's. The two bodies moved in long slow orbits around the same almost-hidden sun, a giant of a radiation source. Its fierceness, dulled by intervening clouds, still turned the atmospheres of its inhabited planetoids, as well as much of nearby space, into a white veil of sometimes glaring brightness.
The nebula not only made interplanetary observation difficult, but it rendered the faster modes of space travel totally unattainable within itself. There was no possibility that human ship or berserker machine could ever achieve effective faster-than-light velocity through these vast, attenuated clouds of matter. Therefore all of the colonized planetoids were separated by long hours or days of travel time, as if they had been light-years apart in more ordinary space. Now, to Domingo and the others watching their own progress as charted by their onboard computers on holographic models of the intervening nebula, their best attainable motion was a painful crawl.
But eventually, long hours after the relief mission had begun and minutes after Baza's first claimed sighting of their goal, the computer-enhanced image of Liaoning ahead was beginning to show a definite change behind the thinning veils. The image was becoming just a little clearer, something marginally better than a blur.
Domingo ordered: "Cut the chatter, everyone. To stations. We're getting near."
With all six ships on full alert, the small relief squadron at last prowled within clear instrument range of its goal. The nearly spherical ball of Liaoning, slightly prolate, showed more and more clearly against the ubiquitous milky background. Still the instruments revealed no sign of the attacking enemy.
"Tight beam, Wilma. Tell them we're here."
The message went out on radio, aimed precisely at the planetoid ahead; no receiver anywhere else should be able to pick it up.
The seconds passed that should have brought an answer, but they did not. And then at last the Pearl was close enough to see the settlements on Liaoning's surface.
To see, rather, the places on the surface where those settlements had been.
Domingo's crew, and those of the other relief ships, in almost silent shock, gazed down at a scene of total devastation. Not a building had been left standing, not a settlement was still recognizable.
They hurtled closer.
Questioning radio beams probed the scorched-looking land below. Still there was no response of any kind. No sign that any berserker still lurked in the area or that the death machines might have been inefficient enough to leave anything still alive behind them when they departed.
The marks of the terrible enemy weapons became plainer and plainer on the surface below, as the Pearl drew nearer and nearer to the planetoid. There appeared to be no survivors.
Hours ago, Domingo had silently made plans for what ought to be done in this worst case. He implemented those plans now, issuing terse orders. There was a small spacegoing launch aboard the Pearl, and he selected three of his crew members to go down to the surface of Liaoning in the launch and directly investigate the death and ruin at close range. The captain himself remained where he was, at the helm of his fighting ship.
Iskander Baza was the first crew member detailed to go down. Polly Suslova, who the captain thought could use the experience, was second. Henric Poinsot, steady and reliable, was the third of the crew to be chosen.
When the launch ejected itself from his ship, Domingo could feel nothing through the Pearl's metal frame or through the field of artificial gravity maintained within the ship, a field usually set, like that of their home planetoid, at Earth normal strength. But he could see, on the stages and screens in front of him, how the long, narrow shape of the smaller vessel dwindled rapidly away toward the scorched surface of the planetoid.
Minutes passed, minutes that brought an almost continuous stream of progress reports from the swiftly receding launch below. The relayed observations added little but detail to the horror already known. So far there was no sign of any survivor out of the hundreds of colonists who had lived here. Now, with Domingo's permission, other ships in the relief squadron sent down launches of their own, descending to different areas on the blasted surface.
The launches landed, one after another, at separated sites. The first reports direct from the surface confirmed the catastrophe. One crew reported finding a small wrecked berserker unit, an automated lander—ground defense here had not been totally ineffective.
At last one of the searchers picked up a faint tone from a survival radio. In less than an hour the launch crews were able to uncover first one human survivor and then another from isolated hideouts. Briefly the rescuers' hopes rose. But that was all. No more people were found alive.
The two survivors were brought up into space and taken aboard one of the other ships of the relief squadron. Then Domingo, while his own crew and others listened in, questioned them on tightbeam communications. He spoke with special gentleness to one of the two, a young girl. In his mind he kept seeing Maymyo in her place.
Both of the people who had been recovered alive were injured, and both of them had tales of horror to tell. The two survivors had been isolated, in deep separate shelters. They were numbed and shaken by what they had been through. They murmured disjointedly of incredible dangers, of being stalked and bombarded by death, and of miraculous escape.
Domingo asked: "How many of them were there? How many berserkers? I don't mean landers. How many of the big machines in space?"
One of the survivors had no idea. The other had heard a report that there had been but a single enemy.
"Leviathan? Old Blue?"
"I don't know. Somebody said that it was . . . that one. People always say it's that, when there's only one . . . I don't know."
A medical person who was on the ship with the survivors and trying to treat them now intervened. The captain ought to cut his questioning as short as possible. The patients were both in a bad way, with shock and other problems.
"I'll keep it as brief as I can. Which way did the enemy go from here? Have you any clue as to that?"
But the survivors, not surprisingly, were able to offer their rescuers no clue. Neither of the stunned humans had seen the enemy approaching their world or attacking it, even on instruments, much less observed its departure.
The captain let them go.
How had the defenses of Liaoning been overwhelmed so quickly? The two numbed, quivering humans had been able to give him no information on that point. The recording devices that were supposed to register combat action might tell the story, but the indications were that none of the ground stations containing those recording devices had survived.
Domingo now ordered his own shipboard instruments turned away from the planetoid, and with them his crew diligently scanned the thin surrounding clouds of white emission and reflection nebula. In the clouds the instruments could find disturbances that told of the recent passage of sizable objects moving at high sublight velocity, as fast as was prudent and maybe a little faster for something that big moving within the nebula. Berserker tracks were left in the nebular fog that was thin enough to count as a fair vacuum. Had there really been only one of the enemy, or more? The disturbances were too fragmentary to tell. And the scanners and computers could find no dependable indication of which way the tracks were leading.
A clamor began to reach the commander from people on the other five ships. Each colonist in the rescue squadron had begun to fear that his or her own family and home on Shubra was now in greater danger than before, perhaps at this very moment already under attack.
"We better get home, Chief."
"We will. We're going home right away, don't panic." Then Domingo reminded them calmly—and some of them began reminding each other—that the automated defenses of Shubra were strong, stronger than those of Liaoning had been, and that they ought to hold, even without their squadron's support, for several days, especially against attack by only a single enemy.
Of course at one time, perhaps only hours ago, the people of Liaoning had probably felt confident in their automated defenses too.
Had those people been given time to get any of their own ships into space? It was impossible to determine the answer to that one conclusively; what had been the Liaoning space harbor, an underground facility much like Shubra's, was now an inferno of nuclear fire. If any ships had been launched, they were nowhere to be seen.
Still, the known power of the Shubran planetary home defense systems gave the people from Shubra a positive thought to cling to, something with which to reassure themselves during the return trip to their own world. That trip now began without further delay.
Domingo saw to it that the two people his squadron had rescued from Liaoning were kept aboard a ship other than his own. There was one ship whose crew included a couple of people that one of the survivors knew, and the two were placed on that. He hoped it might make things a little easier for them. The captain-mayor also wanted to make certain that his own craft was as close as possible to perfect readiness for combat. Having refugees aboard would not contribute to that end and might detract from it. His new ship was the best fighter in the squadron, he was sure, even if it was still untested in battle.
If the trip out from Shubra had seemed long, the journey back again was endless, filled with largely silent horror and impatience. Domingo still held the squadron together, for the same reason he had done so on the journey out. When a berserker had achieved one such successful attack, another one soon, somewhere, was very likely.
No one on his ship wanted to voice the common fear of what they might find on their arrival home, but neither could anyone stop thinking about it. All logic said it was unlikely. There was no reason to believe the berserker had gone from Liaoning to their world rather than somewhere else. But . . .
Polly Suslova, at least, thought that she could sense a faint, silent accusation in the air: that Domingo had guessed wrong. His tactical gamble had failed. It was an unfair accusation, of course. There was nothing else the Shubran ships could have done, under any commander, but respond as they had responded to the urgent distress message from their neighbor colony.
But the response had failed. Instead of intercepting the berserkers, saving Liaoning and putting a stop to the menace for the time being, all that had been accomplished was to save two shattered people and to weaken the defenses of their own home for more than a day.
It would be bad luck indeed if the enemy were to mount a heavy attack on Shubra within that time. But the absence of bad luck could never be relied upon.
And at last the trip home was almost over.
"I've got an image of home on the detectors now, Captain. Maximum range."
Good, thought Domingo. Now within thirty seconds or a minute I will get a further detector report, observation of some surface features, some activity, the beginning of reassurance that all is well at home. There would probably not be any open radio transmissions to pick up. A red alert, which meant radio silence, had been in effect here since the squadron's departure. Those conditions could soon be relaxed somewhat. There was a wedding to carry on with, however Maymyo and Gujar wanted to do it. Any celebration today or tomorrow would have to be severely restricted. It was going to be a while at best before the alert could be canceled completely. Until communications were exchanged with the Base. Until . . .
The thirty seconds had passed, and then thirty more, and the silence on all the instruments was beginning to grow ominous. The visuals were getting clear enough to see now, to allow recognition of something of the familiar surface, anyway . . . but still only ambiguous spots were coming through. There was so much surface cloud, ice crystals blowing . . .
Two seconds later he had to admit it to himself. The surface of Shubra ought not to look like that.
The defense frequencies were not detectable. But they ought not to be, could not be, totally silent at this close range. They could not be, unless the unthinkable should intrude here and now into the actual.
And that could not be happening. No, not that.
Unless . . .
There was no single moment in which the terror became reality. Rather there were minutes in which the members of the relief expedition slowly found their worst fears realized. There was now ruin on Shubra, almost the equal of that they had left behind them on Liaoning.
There were spontaneous outcries from the people aboard the Pearl, and then stunned silence.
The silence did not last long; there followed frantic efforts to communicate with someone, anyone, below. The attempts were as futile as they were desperate.
Still there might be, might be, survivors. The rush to investigate was frenzied. This time Domingo landed the ship, crudely and clumsily; he put the Sirian Pearl down directly on the surface, because here, just as on Liaoning, the space harbor had been effectively destroyed, turned into a gaping wound whose jagged mouth resembled that of a volcano. The deep center of Defense Control had to be gone, too; it could not have survived that cavitation.
As Domingo landed his ship, the other ships of his squadron were coming down as well, landing on the surface close around the Pearl.
The crews all disembarked and then milled around beside their ships, looking for some kind of hope, some indication of human survival. But it was a strange and unfamiliar world on which they stood, protected by their suits and helmets of space armor. The rocks of it still roared and shuddered underfoot. Every building had been wiped away. The atmosphere was poisoned. Fresh snow and black smoke blew together across a cratered, shattered, alien landscape. The artificial gravity was weakening already. The deeply buried generators that created it had doubtless been damaged, and soon the smoke and the snow would be gone, along with all the air . . .
Domingo was commander still, and still mayor of whatever might be left. He had to spend the first minutes giving orders, trying to prevent the disintegration of his crew and the other crews, instead of running in a frenzy to see what had happened to his daughter. An organized search for survivors was begun.
It was only minutes after the search started when the personal news reached him: The bride-to-be, his daughter, along with all her comrades in Defense, was dead.
Duty forgotten, Domingo commandeered the only ground vehicle available—it had come down aboard one of his squadron's ships—and rushed to the scene.
Maymyo's small defense position had been as well protected as any of the other posts near the surface. The only access to the position from the surface was through a bank-vault door set under the overhanging brow of a hardrock cliff. But her nest, like all the others, had been scorched and blasted open. The massive door hung ajar, half torn from its great hinge, the inner and outer surfaces of it alike sagging where they had begun to melt, radiating red heat.
Domingo, protected in his armor, ran in through the unprotected doorway. Enough light came in through it, into the small chamber of steel and hardened rock, for him to see. The poisoned snow was drifting in before him, with him, after him. Her body was almost completely destroyed. At least the pitiful thing, scorched flesh and bone with snow already drifting on it, was assumed to be her body, because here it was at her post; but whoever it was was not wearing space armor, had not been wearing it at death. Chunks of the armor lay nearby, more durable than almost anything else amid the ruin.
When Domingo had jumped into the groundcar and roared away without waiting for Gujar, the younger man had climbed back into his own landed ship and taken off, only to land again almost immediately here by Maymyo's cave. Now, screaming and ranting, his duty and his crew forgotten, he came running into the gutted dugout, past Domingo, to throw himself down at the scene of death. He spent a minute of incoherent grief with the man who was to have been his father-in-law.
Then Gujar gathered up what appeared to be the shreds of wedding gown and, moving at a staggering run, took them back into his ship. On his suit radio Domingo could hear him, muttering half coherently about some kind of positive identification test.
The stricken father remained kneeling in front of the ruin of what had been a human being. All he could think was: Why no space armor? Maymyo would not have taken her armor off in combat. So the blasted body before him was not hers after all. Anyway it was impossible that it should be hers.
Another report was brought to Domingo, who somehow was still numbly functioning. On Shubra, unlike Liaoning, one of the military combat recorders, deeply embedded in the surface of the planetoid, had survived. Enough information had already been extracted from the recorder to confirm the fact of a single attacker. It had been Old Blue, Leviathan, rearmed with improved weapons and with new force-shielding that successfully resisted the weapons employed by Ground Defense.
Leviathan. Standing now in the doorway of the ruined cave, Domingo looked up into the howling sky.
Overhead another ship, a small one, was approaching the surface, coming down to a gentle landing beside the six that had already landed, following their squadron commander. Presently the newcomer's markings could be identified. It carried one of the wedding guests returning.
The small ship landed quietly only fifty or sixty meters away from the cave, and its owner got out of it, alone, and approached the little crowd now gathered around Domingo. The new arrival was Spence Benkovic, who had his own small colony on the only moon of Shubra.
Benkovic was a lean, dark-bearded, youngish man. He had a handsome face and large, expressive eyes. Staring without comment at the small shattered shelter, the covered body, he gave what news he could to the stunned people standing around him.
"When the alarm went off, I thought I'd take a look around myself," he began in a numbed voice. "All I've got is that little one-seat battler! Not real good for a real fight—but I thought I'd see what I could see." A couple of hours later, he reported, he had been patrolling out at maximum detector range, several hundred thousand kilometers from Shubra, hoping to be able to observe any approaching berserkers in time to give warning to the world of the enemy's approach.
"I should have let you know what I was doing, I guess . . ." No one commented; there was no reason to think it would have made any difference.
"Then I thought I saw something, moving in the nebula. Too fast to be just a shoal of life. But it wasn't a berserker, either."
"What, then?" someone was curious enough to ask.
"A drift, maybe." After shoals, drifts were the most common kind of formation in which the local primitive life forms tended to approach the planetoid, where the selective collectors waited for them. "But—so fast. And then I thought that on the detectors it looked like some kind of spacecraft—one ship, or two close together. I don't know whose ship it would have been. But it wasn't berserkers, either, not then, because whatever it was didn't come on to attack."
"Berserkers just scouting? Small units."
"Maybe." Benkovic didn't sound convinced. "Then—Leviathan must have come in on Shubra from one direction while I was off scouting in the other. Didn't take it any time at all to take out the ground stations; it couldn't have taken any time, because in a matter of minutes I was back, close enough to see what was happening. Then . . . I could see it dropping small units right here . . . in this area of the surface."
Domingo raised his head. It was as if he were really seeing Benkovic for the first time. "Leviathan," the captain repeated.
"Yeah. Yeah. I saw Ol' Blue once before, a long time ago. I've been in a fight or two. . . . It put its little units down, right here, directly on the surface, or hovering over it so close as makes no difference . . . there was nothing I could do. I didn't stay close enough to watch. My little battler, hell, there was nothing . . . I went back to my moon, to try to get my own people out. But it had already been there, too."
After a little pause, someone asked: "Who was up there on the moon besides you? I never heard, exactly."
"Three people. Three women. Only one's still alive. Then I tried to broadcast a warning, but the whole area, the planet and moon and everything, was under some kind of jamming.
"Then when I took off and looked around for Old Blue again, it was gone. Missed me somehow, coming and going. And there was—this." Benkovic made an expressive, sweeping gesture encompassing the dead landscape around them.
Domingo turned away from him, looking in another direction. Gujar, still moving like a sleepwalker, was coming back from his own ship. There were still scraps of white material in his hands. In an alien-sounding voice the bridegroom said that he had made a final identification of the wedding gown fragment as Maymyo's. There could be no mistake. There had been exotic fibers woven into it, plant material from his own mother's distant homeworld.
Benkovic looked sick.
Domingo was suddenly sitting down, on a snow-drifted rock, staring at nothing. His face inside the clear plate of his helmet was ghastly. Polly Suslova caught him as he fell.
