Asimov’s Future History Volume 6

by Isaac Asimov

  SilverSide dropped to all fours. With a quick lope, she ran into the forest, moving westward toward the Hill of Stars.

  Howling, the rest of the kin ran behind her.

  Chapter 10

  AN UNEXPECTED MESSAGE, AN UNEXPECTED ARRIVAL

  “KATHERINE ARIEL BURGESS, you’re a fool.”

  The image in the mirror didn’t seem inclined to answer the accusation. Ariel scowled at herself and slapped at the contact. The mirror dissolved in a shimmering crystalline haze and was replaced by a pastoral sunset scene. That only made her more angry, reminding her of the acrimonious morning a week ago.

  She’d told herself that Derec would wait, that he’d still be there when she came back from her long walk. But he hadn’t waited.

  When she’d finally cooled down and called the house in mid-afternoon, Balzac, the household robot, had informed her that Derec and Mandelbrot had left for the port several hours before. Ariel had called the port, wondering what she’d say if he was still there, rehearsing the lines in her mind.

  I’ve changed my mind, Derec. I want to go with you.

  But he’d already gone, and she had no idea where it was he was heading.

  Ariel didn’t know whether that made her angry or sad or both at the same time. She simply felt confused. The intervening days hadn’t made things any better. Sleeping alone each night was too vivid a reminder.

  She came out of the personal, wandering aimlessly through rooms that now seemed far too large and empty. She stared out the windows, fiddled with the reader, flicked on the holovid and as quickly turned if off again.

  With a start, she noticed that the computer terminal was blinking. Feeling a sudden surge of hope, she started to press the access key. Stopped.

  “Balzac?” she called.

  The robot trundled from its wall niche in the next room. “Mistress?” it said in a flat, mechanical voice. Balzac was a utility model, unsophisticated and plain.

  “The message on the terminal. Why didn’t you answer the call?”

  “I monitored the message, but it was for Derec and did not demand a reply.”

  “Who was it from?”

  “‘Who’ is imprecise in this case. The message was a faint relay from a central computer system.”

  Ariel’s lips pressed together. She inhaled slowly, thinking. “Thank you, Balzac. That’s all I require.”

  The robot nodded and left the room. Ariel waited until it was gone and the house was silent again, then spoke her codeword to the terminal: “Euler” — the name of one of the supervisor robots on Robot City. Nothing happened. She wrinkled her nose.

  She knew Derec’s code word as well; he’d made no attempt to keep it a secret from her. “Aranimas,” she said.

  A foil screen scrolled open; glowing letters flickered across it as Ariel leaned closer. The message was short and succinct:

  CITY UNDER ATTACK BY NON-HUMANS. IMPERATIVE WE RECEIVE OUTSIDE AID.

  The message was followed by a sequence of coordinate numbers for the location. Ariel smiled. “Okay, Derec,” she said to the screen. “If the mountain has run away from Mohammed, Mohammed will chase it. Won’t you be surprised when I show up?”

  She turned away from the computer, suddenly excited. This would serve him right. “Balzac!” she called. “I need you to make some arrangements.”

  “Mandelbrot, the Robot City has to be somewhere on that large continent there — see where the two rivers meet in the forested area? The computer says that’s where the last message was ‘waved from.”

  Mandelbrot, at the controls of their craft, punched in coordinates. “Have you been able to get the city’s central computer to respond?”

  “No,” Derec admitted glumly. “Either I’m not doing something right or the chemfets only give me access to the original Robot City’s computer. Before, all I had to do was think a message and it went through. This Central won’t talk to me or the original Robot City’s computer. It’s just beaming out the distress call at regular intervals.”

  “Then it must be expecting someone to answer; otherwise, why signal at all?”

  “I don’t know, I don’t know. I haven’t figured it out yet. I’m just as puzzled as you are.”

  Derec watched the long curve of the world flatten as they approached. It was a pretty world, he decided. He might have chosen it himself. It seemed a calm and gentle place, much like Aurora, though he could see the spiraling arms of a storm just touching the eastern shores of the continent below, and he knew that underneath the pastel blue-white would be dark, streaking clouds and raging winds.

  Untamed, this world was. Which was very unlike Aurora.

  And very much like Ariel.

  The thought crossed his mind, unbidden. She’d not sent any messages to him after she’d stormed out of the house; in fact, she’d disappeared entirely. He’d made calls to a few places trying to find her before they’d left, but to no avail. She seemed to have dropped from sight. It had been very hard to leave without saying goodbye. And because he knew that was exactly the effect she’d been after, he’d gone.

  He’d begun to wonder if she’d be there when he came back. There was a sullen ache in him at the image of an empty house. It was going to hurt. It was going to hurt more than he wanted to think about.

  To take his mind off Ariel, he reached in front of Mandelbrot and toggled a switch to bring the world into closer focus. Unbroken treetops swayed in a light wind.

  “I don’t see any evidence of a city,” he said. “If we weren’t looking specifically for it because of the signal, I’d swear this place was barren of any technology. It has to be there, though. If so, it sure hasn’t spread out as much as the original. Have you seen any evidence of other life, Mandelbrot?”

  “No, Derec. The nightside umbra shows no obvious large habitations, which would be lighted, I would think — though we haven’t seen this continent at night yet. The atmospheric sampling does indicate a small amount of industrial waste, which is very likely the result of your city. You remember the effect the other one had on its environment.”

  Derec did. The massive, out-of-control building spree of the first Robot City had resulted in immense ecological side effects. The horrendous deluges that daily inundated the city had nearly killed both him and Ariel until he’ d reprogrammed the central computer. “Yes, I remember,” he said. “I hope this one keeps a better handle on things. Take us down. Let’s see what’s going on.”

  “Derec, I advise against landing in the city itself. Assuming we can even find it.”

  “Why not, Mandelbrot?”

  The robot’s eyes gleamed as it turned to him. “We do not know what kind of attack this city is facing,” he said. “I have checked for other ships in orbit and found nothing, but I am still concerned that a city under attack will have defenses against ships. You cannot communicate with the central computer. Given that, I would be afraid that it might deem an unidentified ship an enemy and take measures to protect itself.”

  Derec grimaced.

  “If you order me to do so,” Mandelbrot continued, “I will trust your better judgment and follow your orders.”

  Derec shook his head. “Uh-uh. And you’ll say ‘I told you so’ afterward.”

  “No.” The flat delivery almost sounded hurt.

  “Okay,” Derec said, grinning. “I think you’re right. Let’s land elsewhere. How much of a hike were you planning on giving us?”

  “I have estimated that fifty kilometers is the minimum.”

  “Fine. A few days’ stroll through the forest —”

  At that moment, the craft shook like a mad thing. As the hull shuddered, Derec felt Mandelbrot’s firm grip on his arm, guiding him to his seat and forcing him down. The crash webbing slid over him as the craft tumbled; Mandelbrot staggered back to his seat and fought the controls.

  “What happened?” Derec shouted.

  “I do not know. Our orbit is decaying rapidly....” The robot had no time to say more as the ship’s view o
f the world below spun and whirled. Mandelbrot’s robotic reflexes were far faster than Derec’s, but the power to their main engines was simply gone.

  Using the attitude jets, Mandelbrot managed to reduce the wild tumbling momentarily, but then the first tendrils of the atmosphere touched them and the hull struts moaned in agony. The ship began to do gymnastics again, and this time-snared in the planet’s gravity well — they were flung violently with it.

  Derec’s head slammed up against his seat despite the webbing, making him shout in pain. Mandelbrot had cut all the automatics, giving him full control of the ship, but it was of little help. In the viewscreen, they saw the hull turning cherry red; the heat was suffocating in the cabin, the ventilation system gone.

  White cloudtops seemed to race toward them, then they plunged into the columns of gray murk. Storm winds tossed them; rain sheeted across the screen.

  “Mandelbrot!” Derec’s scream shivered with the vibrations of the ship.

  There was no answer.

  They plunged out of the bottom of the storm, the murky landscape below wheeling like a mad carousel. The ground, a fist waiting to crumple them like paper, rushed at them. Then, like the gut-wrenching end of a roller-coaster’s freefall, Derec was shoved down in his seat as the craft pulled up in a quick loop.

  For a moment, Derec thought Mandelbrot had saved them.

  It was still too late.

  The trailing bulk of the engines caught the lip of a rocky outcropping. The granite blade of the hill ripped into the supports. Metal and stone screeched; Derec heard the concussion as the engine exploded. Snared, the ship itself was hammered to the ground. The inferno of the engine was sheared completely off and went spiraling away.

  At least I won’t burn to death.

  As a last thought, it seemed a strange comfort.

  STRATEGY AND TACTICS

  SILVERSIDE BROUGHT THE pack to a ragged halt at a ridge looking down into the shallow bowl of a valley perhaps a kilometer across at its widest point. She sat in the shadows of the last few trees; LifeCrier and KeenEye came forward and sat on their haunches to either side of the new leader. SmallFace was high in the sky; LargeFace had yet to rise. The stars — the VoidEyes, as LifeCrier called them — stared down at the city and marveled.

  SilverSide felt some of that awe herself. The Hill of Stars, set like a glistening diamond in the center of the valley and rising well above the level of the surrounding hills, was a fantastic pattern of glowing lights. The slender pyramidal structure mocked the glory of the night sky.

  Nor was the Hill of Stars all. Other buildings spread out around it in geometric splendor, a procession of hard, crystalline shapes filling the valley and spilling out its open end, all linked by ribbons of walkways.

  And everywhere, everywhere. there were WalkingStones: all different sizes, all different builds, all different colors. They bustled along the walkways, gazed from the windows of the buildings, slid busily between the flanks of the city. There were thousands of them.

  They moved in an eerie, almost mystical silence — at least to the kin. But SilverSide could hear the deafening roar of the city’s voices inside her head. An eternal chatter of orders and instructions came from the central computer; reports were constantly being funneled back to that source. And she understood the words, for they spoke as the Hunter spoke, in that language SilverSide guessed must be that of the Void where the gods lived. It was more proof that the OldMother was being opposed.

  “They began with just the Hill of Stars,” KeenEye whispered to SilverSide. She panted at the remembrance, and her long, furless tail lashed from side to side. “They’ve worked like the krajal since then.”

  SilverSide had seen the industrious insects called the krajal toiling ceaselessly through the undergrowth of the forest, building their mud colonies on the sides of trees. KeenEye pointed a long finger at the periphery of the city, her lips drawn back from canines in a snarl.

  “See how they tear down the trees and destroy the land?” she rasped. “All this valley was forest before the WalkingStones came. They destroy everything to put up their stone caves. And the light — it’s as if the sun were resting down there for the night. The WalkingStones don’t care about kin or any of the living creatures. They don’t care that our prey animals have fled. They don’t care that their stone caves stretch out and out and out. Long before they reach PackHome, we will have left. We will have starved, or we will have been killed.”

  “Do these other WalkingStones hurt the kin like the one we killed?” SilverSide asked. “There must be different species of WalkingStones down there.”

  “We don’t know,” KeenEye answered. “The others have never bothered us. They stay within the stones. Only the Hunters ever come outside.”

  “That also makes them like the krajal,” LifeCrier added. “Only the blue krajali get food, only the yellow-speckled krajali build the tree-homes; only the red krajali defend the homes against the LongTongues. They each have a separate task to do, and they each are shaped a little differently. Maybe it’s the same with these WalkingStones.”

  SilverSide’s optics focused more closely on the hive of activity. What LifeCrier had said sounded like an accurate enough metaphor. The view of the city bore that out. Certainly the WalkingStones seemed specialized in appearance. And though the WalkingStones were obviously constructed things, their hard, unyielding bodies were like the chitinous shells of insects.

  Maybe the enemy of the OldMother had fashioned the WalkingStones after insects. They had the same outward silence, and their chattering inside her head to the unseen Central seemed like the clickings of insects. Like the insect, they labored with seemingly untiring energy; like the krajal they built their own colony home rather than take refuge in what nature afforded. And this Central, perhaps that was the queen, directing all activities of the hive.

  The intricacy and sophistication of the city echoed in SilverSide. It awoke memories of her initial urges: find sentient life. Find humans. She’d made the decision on what was human, but the intelligence behind the WalkingStones...

  ... but that was the province of the gods, or so LifeCrier’s tales had indicated. A god had sent the WalkingStones as a god had sent SilverSide herself. It felt right to admire the genius that had created the WalkingStones, a resonance of the Third Law commands that had shaped her first hours. But admiration didn’t mean that the WalkingStones weren’t enemies. SilverSide had made her choice; the OldMother had sent her to the kin.

  But still... The kin were human, yes, but SilverSide yearned for something more.

  “Sometimes the krajal infest a place, too,” LifeCrier was saying. “The queen breeds and breeds until the trees drip with the shiny bodies. They drop on the prey animals and bite, driving them mad until they flee. They can kill a youngling — a slow and horrible death.”

  LifeCrier closed his eyes, as if remembering. “The last time that happened, two LifeCriers ago, HalfTongue was the leader. During a storm, lightning struck a tree. HalfTongue noticed that the flames killed the krajal and that they fled. She took a branch from the tree and set a blue krajali on fire. The nearby reds came to defend it, leaving an opening. So HalfTongue and the others took several burning brands and began using them to drive the krajal away until they could reach the queen and kill it. Once the queen was dead, the krajal behaved like crazy things and were easy to kill.”

  “WalkingStones won’t burn. You can’t burn a rock.” KeenEye’s comment was laced with her old scorn. If she was resigned to a secondary place in the pack behind SilverSide, she was also not going to submit to any of the other kin. “The WalkingStones would laugh at a burning stick.”

  SilverSide nodded in agreement, scenting KeenEye’s irritation with LifeCrier’s tales. “Still, there is a hint in LifeCrier’s story. I must find out more about these WalkingStones. KeenEye, you will lead the pack in my absence. I will go down into the city. I need to discover if these other types of WalkingStones are m
ore vulnerable than the Hunters. If what I suspect is true, then the Hunters will come after I attack. You must watch — see what they do, see how many they send and how quickly. Then go back to PackHome quickly. I will return by another route after I have made certain that no Hunters follow me.”

  “If you’re not killed right away,” KeenEye said. Her pale eyes were noncommital and SilverSide could not tell if the prospect pleased or disturbed her. “If you’re right about these other WalkingStones.”

  “If anything happens to me, you become leader again,” SilverSide answered. Yes, she scented satisfaction in KeenEye with that, and she continued. “But it won’t. I don’t intend to fight the Hunters. I only need to see how they react so we can plan. You can’t hear them, but I can. The WalkingStones speak; they communicate as do the kin. I can use their language against them. I might be able to deceive them.”

  “GrayMane knew the language of the OldMother,” LifeCrier said. “You see, KeenEye, it is as I said.”

  KeenEye grimaced, but she said nothing.

  “Watch me for the time it would take to skin a deer,” SilverSide told the group. “Remember what you see, every detail. It is very important. Then leave. Go directly back to PackHome.” SilverSide used HuntTongue to accentuate the command.

  KeenEye grimaced again, but she nodded. “As you wish.”

  SilverSide gave a soft bark of satisfaction. She looked at the pack, who watched the trio expectantly. The sight of the kin nudged a First Law circuit. “Keep them safe, KeenEye,” SilverSide said. “Take them back as swiftly as they can go — the Hunters may come after you if I can’t lead them away.”

  “I will do as SilverSide wishes,” KeenEye answered in proud HuntTongue. “She does not have to worry.”

  There was nothing more to say. SilverSide glanced around the edge of the forest, making sure that no Hunters were lurking nearby. Swiftly, she dropped onto four legs and moved out into the wash of moonlight. She was a swift, glinting presence sliding into the shadows of the nearest buildings. SilverSide moved in among them several strides, then hunched down, belly to cool stone behind one of the structures.
