“Not a simple matter, or a small one,” Kresh said. “And there would either have to be two channels dug, or one channel large enough to encompass both a northward and southward flow.”
“We’d need both, actually,” Lentrall said. “One channel that could accommodate two-way flow, and one that would simply serve as a sort of huge pressure-relief valve. The second outlet would not generally carry huge amounts of water, but it would make it possible to regulate the amount of water in the Polar Sea.”
“How do manage to get water to flow in two directions at once through one channel?” Fredda asked.
“Actually, that is one of the more straightforward parts of the business,” said Lentrall. “It happens all the time in natural oceans. The warm water moves on top, while the counterflow of cold water moves on the bottom. A sort of natural temperature barrier, or thermocline, develops. The two currents are quite distinct from each other. They can even have different concentrations of trace elements. For all intents and purposes, they do not intermix. In the present case, the cold counterflow to the south should also serve to scour out the initial channel through the process of water erosion.””You make it all seem so simple,” said Fredda, not making any great effort to keep the sarcasm out of her voice. “Why it is it no one has ever thought of it before?”
But Lentrall was clearly immune to sarcasm, no doubt because he was virtually unable to detect it. “Oh, many people have thought of it before,” he said. “The problem is that no one has been able to find a way to go about digging the necessary channels until now. The job was too big and too expensive to do with any conceivable sort of conventional digging equipment. If we started right now, with an all-out effort to dig the channel, we wouldn’t get halfway done before the climate collapsed.”
“But you, and you alone, have found the way,” said Fredda.
That jibe almost seemed to strike home. “Well, yes,” Lentrall said, suddenly just a trifle cautious. “Yes, I have.”
“How?” asked Fredda. “How in the devil are you going to do it?”
Lentrall was now plainly startled. He looked from Fredda to Alvar and then back again. “You mean he didn’t even tell you that much? He didn’t explain?”
“No,” Fredda said. She glanced at her husband, but it was plain he was not going to say anything. “The governor wanted me to hear it from you.”
“I see,” Lentrall said, clearly taken aback. “I thought you knew that part.”
“But I don’t,” said Fredda, more than a little annoyed. “So I ask you again to tell me now. How are you going to do it?”
Davlo Lentrall fiddled with the map for a moment. He cleared his throat. He sat up straight in his chair, and looked straight at Fredda. “It’s quite simple,” he said. “I intend to drop a comet onto the planet.”

GUBBER ANSHAW SMILED to himself as he strolled along the wide boulevards of Valhalla. He had only been to the hidden city a time or two before, and he was genuinely pleased to return.
Valhalla was a utilitarian place, designed down to the last detail to be efficient, sensible, orderly. The overall design was, ironically enough, reminiscent of underground Spacer cities, but perhaps that was to be expected. Building underground did force certain requirements on the design.
The city was built in four levels. The lower three were a fairly conventional series of storage areas, living quarters, and so on, each connected to the others by broad ramps and high-speed lifts. But Gubber was on the top level of Valhalla, and the top level was something quite unconventional, indeed. It did not remind him of anything at all.
It was an open gallery, a half-cylinder on its side, precisely two kilometers 10ng and one kilometer wide. The side walls of the main level merged smoothly into the wide, curved, ceiling. The entire interior surface of the semicylindrical gallery was coated with a highly reflective white material. The overall effect was overbright to human eyes, but no doubt the New Laws regarded it as a more efficient style of illumination.
The floor of the huge gallery was still in large part empty, though it seemed to Gubber that there were a few new structures in place since his last visit. “Structures” seemed a better word than “buildings,” as many of them did not seem to be buildings, exactly.
There were, of course, a number of normal-seeming installations on the main level, given over to one conventional purpose or another. He could identify repair centers, warehouses, transshipment centers, and so on. But Gubber did not spend much time considering them. Instead, his eye was drawn to the less identifiable structures clustered toward the center of the main level.
All of them were the size of two- or three-story buildings. Nearly all of them were geometric solids of one sort or another: cubes, cones, dodecahedrons, oblate spheroids, three-, four-, and five-sided pyramids, each painted or coated in a bright primary color. A few were positioned in strange attitudes. One cone was upside-down, and two of the pyramids rested on base-edges, so that their apexes were pointed exactly ninety degrees away from the zenith. Gubber had no idea how the New Law robots had kept them from falling over.
He was reminded of a child’s carelessly scattered building blocks. On his last visit, Lacon-03 had described the structures as an experiment in abstract aesthetics, and had launched into an intricate explanation of the theories of beauty and utility currently under discussion in the New Law community.
Some of the structures were occupied or used in some way, while others did not seem to have any access way into their interiors. They were, in essence, abstract sculpture. Gubber did not care for them very much as art, but that was almost incidental. He found it fascinating that the New Laws would construct sculptures in the first place. But did they do so for pleasure, or were they simply compelled to attempt art by the murky demands of the Fourth Law? Did these huge geometric solids appeal to the New Law robots in their own right? Or did these strange beings construct them because they felt they ought to build them, because they wanted to convince themselves they were capable of creating? In short, did they build them because they wanted to, because Fourth Law made them do it, or because they felt it was expected of them, because human cities have public art?
Gubber had been pondering such questions for months now, and was quite pleased to realize he was no nearer an answer. Lacon-03 had never succeeded in explaining things to Gubber’s satisfaction, and Gubber himself had not been able to come up with a good explanation. But that suited him fine. Puzzles lost much of their savor once they were solved. “This place always surprises me,” he said to his host.
“And why is that, sir?” asked Lacon-03.
Gubber chuckled quietly as he made an expansive sweeping gesture with one arm, taking in all of Valhalla. “I suppose because none of this seems the least bit like me,” he said.
Lacon-03 regarded her guest thoughtfully. “I take it, then, that because you invented the gravitonic brain, you expected to see some expression of your own personality in the thing created by beings who possess gravitonic brains?”
“Something like that,” Gubber said. “And I must say, handsome as it is, this is not the sort of city I would design.”
“Interesting,” said Lacon. “We New Law robots have always taken an interest in aesthetics, but I must confess that we have never given much thought to the tastes and opinions of our creators. And, I must confess, what study we have made of the subject has been directing at Dr. Leving, rather than at yourself.”
“I’m not surprised to hear it,” said Gubber. “It is only recently that I have taken an interest in the New Law robots, or even acknowledged my role in creating you. Fredda Leving took my gravitonic brain design, wrote the New Laws herself, and put the laws in the gravitonics without so much as informing me that she had done so, to say nothing of asking my permission.”
“You do not approve of the New Law Robots, then.”
Gubber stopped and regarded his companion with a gentle smile. “In
theory, no,” he said. “I think it was tremendously dangerous and foolhardy for Dr. Leving to do what she did. In practice, I find that I rather like most of the New Law robots I have met. You see the world in a different way than human beings do—and in a different way from Three-Law robots as well.”
“In what way, might I ask?”
Gubber nodded toward his companion, then looked forward and started walking again. “No,” he said. “You tell me. Tell me as we walk the city that is not what I expected. Tell me of the worldview of the New Law robots.”
Lacon-03 thought for a moment as they strolled down the broad center boulevard of Valhalla. “An interesting challenge,’’ she said. “I would venture to guess that no two New Law robots would be able to agree completely on how we see the world. We are a disputive group, I can tell you that much. However, I would say that we are baffled by the outside world—and have the sense that the outside world is baffled by us. Human and Three-Law robots have had endless millennia to work out their relations to each other, to discover how they fit into the universe. We New Law robots have had only about five standard years. During that time, the key thing we have learned is that the universe of humans and Three-Law robots is not the most welcoming of places for those of our kind. At best we have encountered indifference, and, at worst, murderous hostility.”
They came to a large two-story building, positioned to command a spectacular view of the main gallery. It was the main administration building. With Prospero away, Lacon-03 was in charge of the city’s day-to-day operations. Lacon-03 gestured for Gubber to follow her inside, and then went on speaking as they went through the doorway, and then up a curving ramp that led to the upper level of the building. “Coupled with this hostility is the plain fact that we have no real purpose in the world. There is no predestined role for us. We must create one for ourselves—and that is not a quick or simple process. Prospero understands this. Our skills and aptitude in terraforming work offer us opportunities, of course. But Prospero knows it will take time for humans to accept us fully into that work. He also understands that we must keep ourselves safe until such time as we are accepted, and work relentlessly to exploit any chance to better ourselves. I realize that I have not given a complete answer to your question, for the simple reason that we have not yet discovered one for ourselves. We need a place to search for better answers. We need a refuge, a sanctuary, a place to reflect, to study, to plan. Valhalla is all those things. But it is something else. Something far more important.”
Lacon-03 paused at the top of the ramp, Gubber by her side. A wide picture window stood before them. Valhalla’s distinctly inhuman architecture was on proud display just beyond the window frame. “Valhalla,” said Lacon-03, “is our home.”
“ ‘PHASE ONE. INTERCEPTION and stabilization of Comet Grieg and installation of attitude control rockets and main propulsive device.’—I expect that last is a polite term for a massive bomb of whatever sort.” Jadelo Gildern smiled unpleasantly as he looked up from his datapad. “I never have cared overmuch for misused euphemism. The term ‘propulsive device’ is so vague it merely brings the question of what the thing might be to one’s attention.”
“Get on with it, Gildern,” said Simcor Beddle, as he sat back in his lounge chair, his hands folded in his lap, his gaze fixed on the far corner of the ceiling.
“Yes, sir. ‘Phase two. Activation of the main propulsion device. Phase three. Cruise toward planet. Attitude control rockets used to correct and maintain course. Phase four. Controlled breakup of Comet Grieg into separate fragments.’ Lentrall seems not to have decided how many fragments, or of what size. ‘Phase five. Targeting of fragments. Phase six. Impact of fragments on planet.’”
“Burning stars,” said Beddle. “I am not sure I am ready to believe all this. They are planning to use a comet to dig a channel from the sea to the Polar Depression?”
“So it would appear, sir. By targeting the fragments carefully, they mean to line them up like beads on a string, with each smashing into the planet at a carefully chosen spot. In essence the craters will be lined up end to end. They also intend to use oblique strikes.”
“Meaning what?” Beddle asked.
“Instead of hitting the ground straight down, they will target the comet fragments to let them strike at a substantial angle of attack. The end result is that, instead of perfectly round craters, they will get rather long, oval ones.”
“And all this will magically form a link to the sea?”
“No, sir. It does not seem that they expect the impacts will do all the work of digging, but they do expect them to do the vast majority of it. Conventional digging, or what they call moderate-yield zero-radiation fusion devices—in other words, nuclear bombs—would be used to link the craters up to each other. There are other details to the project, of course. But when I say details, I am referring to huge projects that would seem massive undertakings in any other context. The plan calls for redirecting the flow of the River Lethe not once, but twice. Currently the Lethe runs from west to east for some time before turning south to empty into the Great Bay. Prior to the impact, they will dam it above its mm to the south, and force it into a new channel to the north, so that it will scour out a new outlet in the Polar Depression. After the impact, they will link the old and new channels and reverse the flow a second time and the River Lethe will become the Lethe Channel, forming the second outlet between the Polar Sea and the Southern Ocean.”
Beddle got to his feet and looked down on Gildern. “This is madness!” he protested. “I have often been accused of megalomania, but this—this goes far beyond the maddest schemes I ever dreamt of.”
“It certainly is ambitious.”
Beddle looked sharply at Gildern. “You always have been one for understatement. I would almost suspect you of approving of this madness.”
“I must admit that I have an open mind about it all,” said Gildern.
Gildern’s-superior looked surprised. “We will return to that point later, I can assure you,” Beddle said. “How is it you got all this information?” he demanded.
“I broke into Lentrall’s office and took scans of every document I could,” Gildern replied.
“But I thought we had agreed the risk was too great.”
“Lentrall left his office and took his robot with him early this morning. I had been monitoring the building for some time, and knew it was virtually deserted at that hour. I decided it was worth the risk of a quick physical search, and of copying the information from his datapads. I didn’t make any attempt to examine his on-line computer files. There was a much greater risk of discovery in that.”
Beddle nodded, apparently satisfied. “Do you have any sense of how seriously this proposal is being taken?” Beddle asked.
“That I cannot say,” Gildern replied, for once speaking with perfect sincerity. “There is nothing in the papers and datacubes I have examined that would give me any idea. I saw Lentrall’s proposal—but we have nothing to indicate Kresh’s reaction.”
“Other than the fact that Kresh is seeing him for the second time even as we speak.” Beddle frowned thoughtfully. He gestured to a nearby service robot, who immediately brought an overstuffed chair to where he was standing. Beddle sat down close to Gildern and leaned in close. “I almost get the impression that you approve of this—this scheme.”
“I would not go nearly so far. I would say we should not reject it out of hand, once it gets out to the public. And it is sure to get out. Nothing this big can stay hidden for long.”
“That much I agree with. But might I ask your reasons for even considering this comet business?”
“Because even half a morning’s consideration of it has allowed me to do something I have never permitted myself to do, ever before. It has given me the chance to admit to myself that this planet is doomed.”
“I beg your pardon?”
Gildern handed the datapad out into thin air, and his personal robot retrieved it. Gildern leaned forward and
put on a troubled, sincere-looking expression. “Sir, the planet is dying. Despite local successes, despite all our previous best efforts, that continues to be the case. Each of us, deep in our heart of hearts, knows that to be true. If I can step away from the party line for a moment, you know and I know that Alvar Kresh has been a most effective governor. He has accomplished a great deal, and bought the planet a great deal of time. But that is all he has done. It is—or at least it has been—all anyone could do. But deep in our hearts, I think we have all known it was not enough, that we were all doomed. And because we were all going to die no matter what we did, we decided that we might as well amuse ourselves in the meantime with our silly little games of politics and intrigue. The intrigues were harmless, after all, and would change nothing in the end. We were all going to die. But now—now—there is a chance for this world to live! It is a long chance, that I grant you. The risks, the dangers are enormous. But suddenly there isa chance.”
“Hmmph. I see,” said Beddle. “And I suppose that is the only reason this scheme intrigues you.”
“No, sir, it is not. But the notion that we might actually win, we might actually live, certainly changes the rules of the game. If it does so in my mind, I cannot help but think it will do so in the minds of others. They will look at the political landscape in a whole new way. We must take that psychological shift into account in our planning.”
“But you have something more in mind,” Beddle said.
“Yes sir, I do,” Gildern said, his eyes suddenly alive and intent. He gestured toward his personal robot. “That datapad my robot is holding contains technical information and executive summaries of the whole plan. Nowhere in those summaries is the word ‘Settler’ to be found. This is a job the Spacers, the Infernals, can do for themselves. Furthermore, if it succeeds, we will not need the Settlers anymore. A successful comet impact and the subsequent formation of the Polar Sea will have such a huge and positive effect on our climate that the task of reterraforming the planet will be reduced to a series of tasks to be attacked in detail. Large tasks, difficult ones, but ones we Spacers can accomplish on our own—and with significantly less labor in the field.”
