Solly's sigh filled the black, expressing incomprehension for all of them. "So it's poisonous?"
"It's dangerous, sure, because the positrons breaking away from it fly right through flesh like ours. Mostly they never touch a thing in us, because that's how close to phantoms we are—mostly blood, which is almost light. That's why we can see each other so well. But sometimes a beta particle will hit something small on its way through. Could mean nothing or it could kill you on the spot. Eventually it'll get us all."
Oliver fell asleep dreaming of threads of light like concentrations of the foremen's fierce flashes, passing right through him. Shifts passed in their timeless round. They ached when they woke on the warm basalt floor, they ached when they finished the long work shifts. They were hungry and often injured. None of them could say how long they had been there. None of them could say how old they were. Sometimes they lived without light other than the robots' lasers and the stove plates. Sometimes the foremen visited with their scorching lighthouse beams every off-shift, shouting questions and beating them. Apparently cows were disappearing, cylinders of air and oxygen, supplies of all sorts. None of it mattered to Oliver but the spherical geometry. He knew where he was, he could see it. The three-dimensional map in his head grew more extensive every shift. But everything else was fading away….
"So it's the most powerful substance in the world," Solly said. "But why us? Why are we here?"
"You don't know?" Jakob said.
"They blanked us, remember? All that's gone."
But because of Jakob, they knew what was up there: the domed palaces on the lunar surface, the fantastic luxuries of Earth… when he spoke of it, in fact, a lot of Earth came back to them, and they babbled and chattered at the unexpected upwellings. Memories that deep couldn't be blanked without killing, Jakob said. And so they prevailed after all, in a way.
But there was much that had been burnt forever. And so Jakob sighed. "Yeah yeah, I remember. I just thought—well. We're here for different reasons. Some were criminals. Some complained."
"Like Hester!" They laughed.
"Yeah, I suppose that's what got her here. But a lot of us were just in the wrong place at the wrong time. Wrong politics or skin or whatever. Wrong look on your face."
"That was me, I bet," Solly said, and the others laughed at him. "Well I got a funny face, I know I do! I can feel it."
Jakob was silent for a long time. "What about you?" Oliver asked. More silence. The rumble of a distant detonation, like muted thunder.
"I wish I knew. But I'm like you in that. I don't remember the actual arrest. They must have hit me on the head. Given me a concussion. I must have said something against the mines, I guess. And the wrong people heard me."
"Bad luck."
"Yeah. Bad luck."
More shifts passed. Oliver rigged a timepiece with two rocks, a length of detonation cord and a set of pulleys, and confirmed over time what he had come to suspect; the work shifts were getting longer. It was more and more difficult to get all the way through one, harder to stay awake for the meals and the geometry lessons during the off-shifts. The foremen came every off-shift now, blasting in with their searchlights and shouts and kicks, leaving in a swirl of afterimages and pain. Solly went out one shift cursing them under his breath, and never came back. Disappeared. The foremen beat them for it and Oliver shouted with rage. "It's not our fault! There's something out there, I saw it! It's killing us!"
Then next shift his little tendril of a vein bloomed, he couldn't find any rock around the blue: a big bole. He would have to tell the foremen, start working in a crew. He dismantled his clock.
On the way back he heard the footsteps again, shuffling along slowly behind him. This time he was at the entrance to the last tunnel, the pens close behind him. He turned to stare into the darkness with his third eye, willing himself to see the thing. Whoosh of air, a sniff, a footfall on the rail…. Far across the thin wedge of air a beam of light flashed, making a long narrow cone of white talc. Steel tracks gleamed where the wheels of the car burnished them. Pupils shrinking like a snail's antennae, he stared back at the footsteps, saw nothing. Then, just barely, two points of red: retinas, reflecting the distant lance of light. They blinked. He bolted and ran again, reached the foremen at the checkpoint in seconds. They blinded him as he panted, passed him through and into the bullpen.
After the meal on that shift Oliver lay trembling on the floor of the bullpen and told Jakob about it. "I'm scared, Jakob. Solly, Hester, Freeman, mute Lije, Naomi—they're all gone. Everyone I know here is gone but us."
"Free at last," Jakob said shortly. "Here, let's do your problems for tonight."
"I don't care about them."
"You have to care about them. Nothing matters unless you do. That blue is the mind of the moon being torn away, and the moon knows it. If we learn what the network says in its shapes, then the moon knows that too, and we're suffered to live."
"Not if that thing finds us!"
"You don't know. Anyway nothing to be done about it. Come on, let's do the lesson. We need it."
So they worked on equations in the dark. Both were distracted and the work went slowly; they fell asleep in the middle of it, right there on their faces.
Shifts passed. Oliver pulled a muscle in his back, and excavating the bole he had found was an agony of discomfort. When the bole was cleared it left a space like the interior of an egg, ivory and black and quite smooth, punctuated only by the bluish spots of other tendrils of monazite extending away through the basalt. They left a catwalk across the central space, with decks cut into the rock on each side, and ramps leading to each of the veins of blue; and began drilling on their own again, one man and robot team to each vein. At each shift's end Oliver rushed to get to the egg-chamber at the same time as all the others, so that he could return the rest of the way to the bullpen in a crowd. This worked well until one shift came to an end with the hoist chock-full of the ore. It took him some time to dump it into the ore car and shut down.
So he had to cross the catwalk alone, and he would be alone all the way back to the pens. Surely it was past time to move the pens closer to the shaft heads! He didn't want to do this….
Halfway across the catwalk he heard a faint noise ahead of him. Scrick; scriiiiiiik. He jerked to a stop, held the rail hard. Couldn't reach the ceiling here. Back stabbing its protest, he started to climb over the railing. He could hang from the underside.
He was right on the top of the railing when he was seized up by a number of strong cold hands. He opened his mouth to scream and his mouth was filled with wet clay. The blue. His head was held steady and his ears filled with the same stuff, so that the sounds of his own terrified sharp nasal exhalations were suddenly cut off. Promethium; it would kill him. It hurt his back to struggle on. He was being carried horizontally, ankles whipped, arms tied against his body. Then plugs of the clay were shoved up his nose and in the middle of a final paroxysm of resistance his mind fell away into the black.
The lowest whisper in the world said, "Oliver Pen Twelve." He heard the voice with his stomach. He was astonished to be alive.
"You will never be given anything again. Do you accept the charge?"
He struggled to nod. I never wanted anything! he tried to say. I only wanted a life like anyone else.
"You will have to fight for every scrap of food, every swallow of water, every breath of air. Do you accept the charge?"
I accept the charge. I welcome it.
"In the eternal night you will steal from the foremen, kill the foremen, oppose their work in every way. Do you accept the charge?" I welcome it.
"You will live free in the mind of the moon. Will you take up this charge?"
He sat up. His mouth was clear, filled only with the sharp electric aftertaste of the blue. He saw the shapes around him: there were five of them, five people there. And suddenly he understood. Joy ballooned in him and he said, "I will. Oh, I will!"
A light appeared. Accustomed a
s he was either to no light or to intense blasts of it, Oliver at first didn't comprehend. He thought his third eye was rapidly gaining power. As perhaps it was. But there was also a laser drill from one of the A robots, shot at low power through a cylindrical ceramic electronic element, in a way that made the cylinder glow yellow. Blind like a fish, open-mouthed, weak eyes gaping and watering floods, he saw around him Solly, Hester, Freeman, mute Elijah, Naomi. "Yes," he said, and tried to embrace them all at once. "Oh, yes."
They were in one of the long-abandoned caverns, a flat-bottomed bole with only three tendrils extending away from it. The chamber was filled with objects Oliver was more used to identifying by feel or sound or smell: pens of cows and hens, a stack of air cylinders and suits, three ore cars, two B robots, an A robot, a pile of tracks and miscellaneous gear. He walked through it all slowly, Hester at his side. She was gaunt as ever, her skin as dark as the shadows; it sucked up the weak light from the ceramic tube and gave it back only in little points and lines. "Why didn't you tell me?"
"It was the same for all of us. This is the way."
"And Naomi?"
"The same for her too; but when she agreed to it, she found herself alone."
Then it was Jakob, he thought suddenly. "Where's Jakob?"
Rasped: "He's coming, we think."
Oliver nodded, thought about it. "Was it you, then, following me those times? Why didn't you speak?"
"That wasn't us," Hester said when he explained what had happened. She cawed a laugh. "That was something else, still out there…."
Then Jakob stood before them, making them both jump. They shouted and the others all came running, pressed into a mass together. Jakob laughed. "All here now," he said. "Turn that light off. We don't need it."
And they didn't. Laser shut down, ceramic cooled, they could still see: they could see right into each other, red shapes in the black, radiating joy. Everything in the little chamber was quite distinct, quite visible.
"We are the mind of the moon."
Without shifts to mark the passage of time Oliver found he could not judge it at all. They worked hard, and they were constantly on the move: always up, through level after level of the mine. "Like shells of the atom, and we're that particle, busted loose and on its way out." They ate when they were famished, slept when they had to. Most of the time they worked, either bringing down shafts behind them, or dismantling depots and stealing everything Jakob designated theirs. A few times they ambushed gangs of foremen, killing them with laser cutters and stripping them of valuables; but on Jakob's orders they avoided contact with foremen when they could. He wanted only material. After a long time—twenty sleeps at least—they had six ore cars of it, all trailing an A robot up long-abandoned and empty shafts, where they had to lay the track ahead of them and pull it out behind, as fast as they could move. Among other items Jakob had an insatiable hunger for explosives; he couldn't get enough of them.
It got harder to avoid the foremen, who were now heavily armed, and on their guard. Perhaps even searching for them, it was hard to tell. But they searched with their lighthouse beams on full power, to stay out of ambush: it was easy to see them at a distance, draw them off, lose them in dead ends, detonate mines under them. All the while the little band moved up, rising by infinitely long detours toward the front side of the moon. The rock around them cooled. The air circulated more strongly, until it was a constant wind. Through the seismometers they could hear from far below the rumbling of cars, heavy machinery, detonations. "Oh they're after us all right," Jakob said. "They're running scared."
He was happy with the booty they had accumulated, which included a great number of cylinders of compressed air and pure oxygen. Also vacuum suits for all of them, and a lot more explosives, including ten Boesmans, which were much too big for any ordinary mining. "We're getting close," Jakob said as they ate and drank, then tended the cows and hens. As they lay down to sleep by the cars he would talk to them about their work. Each of them had various jobs: mute Elijah was in charge of their supplies, Solly of the robot, Hester of the seismography. Naomi and Freeman were learning demolition, and were in some undefined sense Jakob's lieutenants. Oliver kept working at his navigation. They had found charts of the tunnel systems in their area, and Oliver was memorizing them, so that he would know at each moment exactly where they were. He found he could do it remarkably well; each time they ventured on he knew where the forks would come, where they would lead. Always upward.
But the pursuit was getting hotter. It seemed there were foremen everywhere, patrolling the shafts in search of them. "Soon they'll mine some passages and try to drive us into them," Jakob said. "It's about time we left."
"Left?" Oliver repeated.
"Left the system. Struck out on our own."
"Dig our own tunnel," Naomi said happily.
"Yes."
"To where?" Hester croaked.
Then they were rocked by an explosion that almost broke their eardrums, and the air rushed away. The rock around them trembled, creaked, groaned, cracked, and down the tunnel the ceiling collapsed, shoving dust toward them in a roaring whoosh! "A Boesman!" Solly cried.
Jakob laughed out loud. They were all scrambling into their vacuum suits as fast as they could. "Time to leave!" he cried, maneuvering their A robot against the side of the chamber. He put one of their Boesmans against the wall and set the timer. "Okay," he said over the suit's intercom. "Now we got to mine like we never mined before. To the surface!"
The first task was to get far enough away from the Boesman that they wouldn't be killed when it went off. They were now drilling a narrow tunnel and moving the loosened rock behind them to fill up the hole as they passed through it; this loose fill would fly like bullets down a rifle barrel when the Boesman went off. So they made three abrupt turns at acute angles to stop the fill's movement, and then drilled away from the area as fast as they could. Naomi and Jakob were confident that the explosion of the Boesman would shatter the surrounding rock to such an extent that it would never be possible for anyone to locate the starting point for their tunnel.
"Hopefully they'll think we did ourselves in," Naomi said, "either on purpose or by accident." Oliver enjoyed hearing her light laugh, her clear voice that was so pure and musical compared to Hester's croaking. He had never known Naomi well before, but now he admired her grace and power, her pulsing energy; she worked harder than Jakob, even. Harder than any of them.
A few shifts into their new life Naomi checked the detonator timer she kept on a cord around her neck. "It should be going off soon. Someone go try and keep the cows and chickens calmed down." But Solly had just reached the cows' pen when the Boesman went off. They were all sledgehammered by the blast, which was louder than a mere explosion, something more basic and fundamental: the violent smash of a whole world shutting the door on them. Deafened, bruised, they staggered up and checked each other for serious injuries, then pacified the cows, whose terrified moos they felt in their hands rather than actually heard. The structural integrity of their tunnel seemed okay; they were in an old flow of the mantle's convection current, now cooled to stasis, and it was plastic enough to take such a blast without shattering. Perfect miners' rock, protecting them like a mother. They lifted up the cows and set them upright on the bottom of the ore car that had been made into the barn. Freeman hurried back down the tunnel to see how the rear of it looked. When he came back their hearing was returning, and through the ringing that would persist for several shifts he shouted, "It's walled off good! Fused!"
So they were in a little tunnel of their own. They fell together in a clump, hugging each other and shouting. "Free at last!" Jakob roared, booming out a laugh louder than anything Oliver had ever heard from him. Then they settled down to the task of turning on an air cylinder and recycler, and regulating their gas exchange.
They soon settled into a routine that moved their tunnel forward as quickly and quietly as possible. One of them operated the robot, digging as narrow a shaft as they cou
ld possibly work in. This person used only laser drills unless confronted with extremely hard rock, when it was judged worth the risk to set off small explosions, timed by seismometer to follow closely other detonations back in the mines; Jakob and Naomi hoped that the complex interior of the moon would prevent any listeners from noticing that their explosion was anything more than an echo of the mining blast.
Three of them dealt with the rock freed by the robot's drilling, moving it from the front of the tunnel to its rear, and at intervals pulling up the cars' tracks and bringing them forward. The placement of the loose rock was a serious matter, because if it displaced much more volume than it had at the front of the tunnel, they would eventually fill in all the open space they had; this was the classic problem of the "creeping worm" tunnel. It was necessary to pack the blocks into the space at the rear with an absolute minimum of gaps, in exactly the way they had been cut, like pieces of a puzzle; they all got very good at the craft of this, losing only a few inches of open space in every mile they dug. This work was the hardest both physically and mentally, and each shift of it left Oliver more tired than he had ever been while mining. Because the truth was all of them were working at full speed, and for the middle team it meant almost running, back and forth, back and forth, back and forth…. Their little bit of open tunnel was only some sixty yards long, but after a while on the midshift it seemed like five hundred.
The three people not working on the rock tended the air and the livestock, ate, helped out with large blocks and the like, and snatched some sleep. They rotated one at a time through the three stations, and worked one shift (timed by detonator timer) at each post. It made for a routine so mesmerizing in its exhaustiveness that Oliver found it very hard to do his calculations of their position in his shift off. "You've got to keep at it," Jakob told him as he ran back from the robot to help the calculating. "It's not just anywhere we want to come up, but right under the domed city of Selene, next to the rocket rails. To do that we'll need some good navigation. We get that and we'll come up right in the middle of the masters who have gotten rich from selling the blue to Earth, and that will be a very gratifying thing I assure you."
