Across a Billion Years
The robot.
"My flesh began to crawl with amazement," it always says in the old horror stories. Until that moment I was never able to understand how flesh could crawl, but now I knew, for my flesh was crawling in all directions. I had seen a billion-year-old film show me the construction of this vault; and I had seen the robot of the High Ones take up its position on the floor, a billion years ago, when trilobites and jellyfish ruled Earth; and here I stood, pumping a neutrino beam into that vault and seeing the robot still occupying the same place, and I tell you, Lorie, I was awed right out of my snuff.
I described the scanner readings to those in the ship. My suit radio dimly brought me sounds of shouts and celebrations from up there.
"Don't go anywhere," Dr. Schein said. "We're coming down!"
The ship shortly broke out of its parking orbit and went into an entry approach. Ludwig made a picture landing. The ship floated nicely down and settled smoothly in the nearby plain. Then the hatches opened and people came pouring out, and we held another festival of foolishness, dancing madly around the neutrino magnetometer.
Now all we have to do is get the vault open. That's all.

We're still trying, as I dictate this three days later.
Removing the laminated slabs of stone covering the door was easy. Kelly cored through until she touched metal, and Mirrik tusked the debris away. It took the two of them almost six hours to lay bare the entire door, which is about seven meters high, four meters wide, and, according to our scans, a meter thick. The High Ones didn't bother with a keyhole; and in any case we don't have the key.
We don't dare blast the door, not with all that High Ones machinery inside. And we aren't carrying a laser powerful enough to slice through a one-meter thickness of metal. We do have a power winch aboard the ship, and we tried it this morning; we fastened magnetic grapples to the door, ran cables to the winch, and pulled, but the door didn't budge and there was real danger that our cables would snap under the strain.
408b spent some time studying the hinge this afternoon. He thinks our best bet is to attack the door from that side: pull out the pin of the hinge, somehow, and swing the door open. But the hinge is about five meters long and the pin alone looks like it weighs a couple of tons. Furthermore, that thing hasn't budged in a billion years, and even on an asteroid without atmosphere or water there's bound to have been some degeneration of the metal, maybe even complete bonding of pin to hinge. In that case we're in trouble. We'll see in the morning.

December 31
A strange, grim, and busy day.
Unless we've lost track entirely, which is quite possible, this is the last day of 2375. But a New Year's Eve celebration seems irrelevant tonight, after the day's hectic events.
We went to work on the hinge first thing in the morning. Before making any attempt to remove it, we did a complete survey of it, with a tridim scan, measurements, holograms, the works, just as though it were a house beam or something that had to be destroyed in the course of an excavation. Not that the science of paleotechnology had much to learn from it, for it wasn't a particularly alien kind of hinge; there is evidently only one efficient way to design a hinge for a door, and the High Ones had hit on the same scheme used on Earth and everywhere else, so that the main point of interest about this hinge was how uninteresting it was.
After this we got the most potent laser in the ship and started cutting. It took a couple of hours to slice the hinge the long way. At last we peeled it open and slipped the pin. Next we got the magnetic grapples out, cabled them to the power winch, and started tugging.
The cables went taut, and we cleared back, not wanting to be close at hand if they snapped. But the cables held. So did the door. Captain Ludwig threw the throttle of the winch wide open, so that it was pulling with its full fifty-ton force, but the tug-of-war remained a standoff. "What happens," Steen Steen asked, "if the winch pulls the ship toward the door, instead of the door toward the ship?" And it was a sharp point, because the pull the winch was now exerting was nearly enough to handle the ship's own mass and send it toppling forward.
The door yielded first.
It opened on the hinge side by about a centimeter. Ludwig changed a setting on the winch. The door slid reluctantly forward another centimeter. Another. Another.
What scared Ludwig—and the rest of us—was what might happen if the door suddenly gave up altogether and came flying out of its socket. The winch, to take up the tension, might very well haul the door toward the ship so fast there'd be a collision, and the ship would be demolished. Ludwig hovered over the controls of that winch like a virtuoso playing a chromosonic organ in a galactic music competition.
Slowly he peeled the door open.
We realized now that a bolt ran from the door deep into the rock of the hillside. That bolt was bending as the winch pulled on the door from the hinge side. Suddenly the bolt slipped from the rock; instantly Ludwig fed slack to the cable and choked down the winch, and the vast door toppled out of its frame, tipped up on one side, and fell forward, opening the way into the vault.
408b was the first to reach the open vault. It scrambled up onto the fallen door and stood there a moment, peering in and waving its tentacles about in excitement. This was the climactic moment of 408b's career: the specialist in paleotechnology was staring into a room packed with High Ones machinery in perfect preservation. Just as Jan and I reached the door, 408b rushed ecstatically forward into the vault.
A blinding bolt of yellow light burst from the top of the open doorway. For an instant the entire opening was ablaze. Jan and I stumbled backward, covering our eyes; and when we took our hands away the brightness was gone. And so was 408b. Nothing remained of it but two charred tentacles just within the doorway.
I've never seen death—permanent death—before. I once saw a construction accident, and a couple of pedestrian fatalities, but each time, a freezer truck arrived within minutes, and the victim was hustled off to a resurrection lab for repairs. You don't think of something like that as death, merely an interruption. But 408b was gone. Beyond hope of resurrection; scattered atoms can't be brought together and given new life. All its skills, its fund of knowledge, its hope of future attainments . . . gone.
In a civilization where most deaths are so temporary, a real death is a terrifying, shattering thing to behold. The rest of us gathered in a dazed little group in front of the vault. Jan began to cry; I put my arms around her, then found I felt like crying too, but I didn't. Mirrik prayed, Pilazinool removed and replaced his right arm about twenty times in two minutes, Dr. Schein cursed quietly, Steen Steen had a fit of the shakes, and Leroy Chang turned away, sitting on the edge of the door in a limp heap. Dr. Horkkk was the only one who seemed in full control of himself. "Away from the opening!" he shouted, and as we backed away he picked up a pebble and tossed it in. The lightning flared again.
We weren't going to be able to get into the vault. That was quite clear.
The death of 408b left us too stunned to proceed immediately. We retreated to the ship, where at Dr. Schein's request Mirrik conducted a memorial service for the paleotechnologist. Not even Mirrik had any idea what sort of religion they have on Bellatrix XIV, so he delivered a Paradoxian service, short and somehow moving. I won't try to reproduce it here; I can only recall one piece of it, the most characteristically Paradoxian of all: "Thou endest our time to teach us that time is without an end. Thou shortenest our days so that our days may be made long. Thou makest us mortal so that eternity will be ours. Forgive us, O Father, as we forgive Thee. Amen."
An hour later we cautiously returned to the vault.
Naturally our mood was dark and bleak; yet we doubted that 408b would have wanted us to go into prolonged mourning on its account when there was important work to do. We had rigged floodlights on the plain to work by during the cutting of the hinge; now we moved them closer, so they would illuminate the interior of the vaul
t. Keeping a wary distance from the entrance, we looked in, and I shivered a little with the chilly shock of recognition as I saw before me precisely the scene depicted in the globe sequence.
A six-walled chamber. Alien, mysterious instruments mounted in back, screens and levers and nodes and panels. Seated in the center of everything, ponderous as a tribal idol, the giant robot whom the High Ones left to guard this cave ten million centuries ago.
Time had not been able to erode the mechanisms within this cave. The blaze of light that ended the life of 408b was ample proof of that.
Nor had time harmed the robot. Incredibly, it still functioned; the combination of High Ones engineering skill and a protective environment of vacuum had given it the ability to withstand all decay. As our lights flashed across its domed head, we saw its vision panel changing hues in response—the robot equivalent of blinking, I guess. Otherwise it gave no sign of awareness. We confronted it, standing in a row outside the vault and not daring to go near, for many minutes.
What now? We were stymied.
Then I remembered the globe and our plans for using it as a means of communication. I reminded Dr. Schein of this, and he sent me back to the ship to get it.
The globe was mounted on rollers now. I pushed it within twenty meters of the vault entrance.
"Switch it on," Dr. Schein ordered.
My hand found the stud. The sphere of greenish light took form around me, widening until its perimeter reached across the threshold of the vault. Images of the High Ones began to swim in the air. Their airy cities, their rooms, their highways, even the sequence of the construction of this very vault, came into view. The robot's vision panel flickered madly; its glow raced through the visible spectrum, descending from high purple to deep red, and tumbling into the infrared, where I saw nothing but felt the sudden hot glow emanating from the vault.
The robot stirred.
Slowly, awkwardly, like an Egyptian mummy awakening from a sleep of millennia, the seated robot rose, pitching forward into a kind of squatting posture, then unfolding its pillar-like legs. We watched, frozen, terrified, fascinated, as the huge thing came to its full height of at least three and a half meters. It stood erect for perhaps a minute, testing its four arms, extending them as if stretching. It contemplated the scenes that were coming from the globe.
Then it began solemnly to stride out of the vault toward us.
Everyone about me panicked and began to run. I held my ground, more out of bewilderment than courage. And so I stood alone as the robot emerged from the vault and drew near me, a gleaming metal colossus nearly twice my own height.
Two of its arms reached down. Webbed metal fingers slid from recesses in the fist-like swellings at the end of each arm. Gently the fingers engulfed the globe. The robot took it and raised it high above its head, as though about to hurl it down at me with terrible force.
I turned and raced toward the ship, not bothering at all to compensate for the gravity, simply leaping and bounding along. Eager hands reached for me and pulled me in.
I looked back. The robot had not budged. Like a titan holding a world in its grip, it still held the globe aloft. Motionless, lost in a billion-year-old dream, it stared up at it.
Two hours have passed now, since I came into the ship. In that time the robot has remained quite still; and we have huddled within the ship, baffled, frightened, yet deeply curious. Dr. Horkkk, Dr. Schein, and Pilazinool are once more conferring, up front in the ship's control cabin. I have no idea what happens next. We've fulfilled our gaudiest dreams; we've come straight to the asteroid where the High Ones built their vault, have found the vault, have found the robot still in working order. It's all like the kind of dreams that addicts buy in sniffer palaces. But now reality has broken in on the dream. The robot waits for us out there. One of us already is dead. Do we dare meet the challenge? Or, having made the archaeological discovery of the epoch, will we go slinking away in quonking terror? I don't know.
And the robot still waits, as it's waited for a billion years.
THIRTEEN
January 2, 2376
The Asteroid
Yesterday morning Pilazinool called for volunteers to go out and attempt to communicate with the robot. Jan's hand was the first to rise; mine followed, and then most of the others, with the notable exceptions of Steen Steen and Leroy Chang. The group that finally went included Pilazinool, Dr. Horkkk, Mirrik, and me. Jan didn't like having to stay behind, but I was relieved that she wasn't picked.
We crossed the bare rocky plain in single file, Pilazinool leading, Mirrik in the rear. All of us except Dr. Horkkk were armed; I carried a positron gun that was probably capable of blowing the robot up, but I wasn't sharp on using it.
When we were within twenty meters of the robot we halted and fanned out widely. Dr. Horkkk stepped forward. In his left hands he carried a little blackboard; in one of his right hands he held an inscription node. The robot took no notice of him. It still stood as though a statue, holding the globe aloft, though images no longer came from it.
Dr. Horkkk slowly waved the inscription node from side to side, trying to catch the robot's attention. That took courage. The robot might be easily annoyed. After a few minutes Dr. Horkkk began to copy the hieroglyphics from the inscription node onto his blackboard, keeping the blackboard turned so that the robot could see what was happening. The idea was to demonstrate to the robot that we are intelligent creatures, capable at least of copying High Ones writing even if unable to understand it.
"Suppose what he's copying is obscene?" Mirrik murmured. "Or unfriendly? What if it makes the robot angry?"
Dr. Horkkk went on sketching hieroglyphics. Gradually the robot started to show interest in him. It lowered the globe to chest-height. It stared down at the small Thhhian, and the colors of its vision panel darkened; pale greens and yellows gave way to rich maroon, shot through with crimson threads. The equivalent of a frown, maybe? The colors of deep concentration? Dr. Horkkk's inscription node suddenly went blank, and a new inscription appeared. Calmly Dr. Horkkk erased his blackboard and began to copy the current message. The robot seemed impressed. From somewhere within its cavernous chest there boomed sounds that our suit radios were able to pick up.
"Dihn ahm ruuu dihn korp!"
Who knows what it means? But we assume that it's in the language of the High Ones.
Dr. Horkkk took another calculated risk. He put down his blackboard, stepped forward three paces, and said in clear tones, "Dihn ahm ruuu dihn korp!"
It was an excellent imitation. But for all Dr. Horkkk knew, he was accepting a challenge to a duel, casting aspersions on the robot's ancestry, or agreeing that he deserved to be obliterated on the spot. However, the robot's reaction was mild. It flashed a stream of violet light along its vision panel, extended its leftmost arm in a kind of beckoning gesture, and said, "Mirt ahm dihn ruuu korp."
"Mirt ahm dihn ruuu korp," Dr. Horkkk repeated.
"Korp mirt hohm ahm dihn."
"Korp mirt hohm ahm dihn."
"Mirt ruuu chlook."
"Mirt ruuu chlook."
And so on for several minutes. After a while Dr. Horkkk ventured to mix up the now-familiar words, rearranging them into new patterns to give a pretense at conversation: "Ruuu mirt dihn ahm" and "Korp ruuu chlook korp mirt" and so forth. This had the virtue of showing the robot that Dr. Horkkk was something other than some kind of recording machine, but it must have been puzzling to it to be getting these gibberish responses to its statements.
Then the robot turned on the globe. The scene that took form about us was the sequence of the construction of the vault, beginning as usual with the wide-angle view of the galaxy, then the close-up of the immediate stellar neighborhood. The robot pointed to the pattern of projected stars. Then it switched the globe off and pointed first to the very different pattern of stars in the present-day sky of the asteroid, then to the burned-out dwarf star.
That seemed intelligible enough. The robot was telling us that it rea
lized, from the astronomical changes it observed, that a vast span of time must have elapsed since it had been sealed into the vault.
The robot now made some adjustment on the globe, and the scene of the High Ones' city appeared. For several minutes we watched once more the High Ones moving solemnly and gracefully through their wonderland of cables and dangling structures. The robot cut it off, pointed again to the stars, pointed to Dr. Horkkk, pointed to itself, pointed to Dr. Horkkk.
Abruptly the robot turned and strode into the vault. It did something at one of the instrument panels in the rear; then it beckoned unmistakably to us. We hesitated. The robot beckoned again.
"Possibly it turned off the lightning field," Pilazinool said.
"And possibly it didn't," said Dr. Horkkk. "This may be a trick designed to make us go to our deaths."
"If the robot wanted to kill us," I pointed out, "it wouldn't need to trick us. It's got weapon attachments in its arms."
"Certainly," said Pilazinool. "Tom's right!"
Still, none of us went into the vault. The robot made its beckoning gesture a third time.
Dr. Horkkk found another pebble and pitched it across the threshold of the vault. No blast of lightning. That was reassuring.
"Shall we risk it?" Pilazinool asked.
He started forward.
"Wait," I heard myself saying, as another fit of heroism rushed through my brain. "I'm less important than the rest of you. Let me go, and if I make it—"
Telling myself that at the worst it would be a quick, clean finish, I leaped up on the fallen door, stepped into the vault, and lived to tell the tale. Pilazinool followed me; then, somewhat more cautiously, Dr. Horkkk. Mirrik remained outside at Pilazinool's suggestion; in case this did turn out to be a trap, we needed a survivor to explain what had happened to the others.
Instinctively we stayed close to the entrance of the vault and made no sudden moves that might alarm our huge host. We still didn't know if the robot's intentions were friendly. Much as we wanted a close look at those complex, cluttered instrument panels on the rear walls of the vault, we didn't dare approach them, for that would have required us to get between the robot and its instruments. The robot might not have liked that.
