The Core

Matteo told it simply, and in pieces, resting between sentences.

He was not a good storyteller. Fifteen years of silence had worn the habit out of him. He would begin a thought and lose the end of it, and sit with his lips moving, and then come back, abashed, with an apology for the delay. Archie sat on the nothing beside him and did not interrupt. The great web of light turned above them, soundless and slow.

"The Gate was never meant to be a door," Matteo said. "It was a lens. Luca and Diana and I, we wished only to map the places the mind goes when it is nearly gone. Dreams, we thought. Death-dreams. A shared language of the dying." He smiled faintly. "We were children. We thought we were scientists."

"What happened?"

"We found that the places were not dreams. They were made. They had edges, and rules, and they pushed back." The silver-ringed eyes were far away. "Something had to hold them. A system must have a center. And the center, in an architecture made of human minds, is a mind."

"You."

"I went in first, with the others. I walked the five Spaces. I found Elena in her throne room, and Gregor in his ship, and I," he stopped. "Sera. I was careful of her. I had her in my arms when the first rule fell."

"The Guardian rule."

"Yes." The thin hand turned, and the five cables of light throbbed in sympathy. "The system will not run without a keeper in each Space. One who remains. It was not built to be cruel. It was built the way a bridge is built, with a pier at every span. When the first of us went down, the bridge took her. When the second, the same. By the time I understood, it had taken them all, and only the Core was left to hold."

"So you held it."

"Somebody had to." He shrugged his birdlike shoulders. "I had the notes in my head. I had a theory. I thought, if I sat very still, I might find the thread that unpicks it. A loophole in the rule." He looked down at his hands. "It has been fifteen years. I think I am close. But I am so very tired."

…

"There are notes," said Archie.

"Yes."

"Luca would want them. He would give his arm for them."

"They are here." Matteo gestured, vaguely, at the dark. "Somewhere. In the lattice. I wrote them as I went, in the language of the system, because there was no paper. A great many pages. It is," a rueful flicker, "not well organized."

"Can you give them to me?"

"I can open them. But you would not read them." The eyes were kind. "It is not for readers. It is a map of the system's own thoughts. It would take someone who could think like the machine." He paused. "Your friend with the spectacles. The one who thinks in code."

"Jin."

"Yes. He would see it."

"Then I'll bring him."

"If there is time." The thin man's voice faded to a thread. "There may not be. I am not what I was. The cables are heavy, and the world above is not kind to the lattice. Something is eating at the edges." He lifted a trembling finger to the far side of the dome. "Look."

…

Archie looked.

The distant web, which had seemed so perfect, had a stain upon it. A cluster of filaments, near the rim, had gone from silver to a sickly gray. As he watched, a tiny knot of them flickered and winked out, and the dark spread outward, delicately, like frost on a pane.

"What is that?"

"Damage."

"From what?"

"From outside." Matteo's face was grave. "From the lab. Someone is knocking at the lattice. He has been at it for days. Hammering, with a very clever tool, at the places where my brother's locks are weakest. I have been holding him off." He winced, as though at an old pain. "I am nearly out of strength."

"William."

"Is that his name?"

"It's the man who paid for the Institute. He wants the Core. He wants," Archie searched for the shape of it, "the system, whole. To sell."

"Ah." The tired eyes closed. "Then he has come at last."

"He isn't here, though. He can't be. He's in the lab, four days away from a court order."

"Is he?"

The question hung in the air.

Then, from behind them, from the far side of the pillar, a dry amused voice said:

"Archie."

…

He knew it before he turned.

It came out of the dark in the unhurried glide of a man walking into a boardroom he owns. A tall figure in a charcoal suit, with a silver watch and an air of faint well-groomed amusement. But it was not quite a man. It flickered at the edges, with a thin electric buzz like an insect on a window. Its feet did not touch the floor. Where its shadow ought to have been, a smear of green code ran down its heels and vanished.

"William," said Archie.

"Well, well." The avatar spread its hands. "Mr. Moran. You've made good time. I didn't expect you for another day, to be honest." The smile was perfect. "I'd say congratulations. You've made it to the end of the game, and your friends aren't even with you. How very Napoleonic."

"You're in the Core."

"I'm in the Core." William looked about with open pleasure. "Isn't it magnificent? I've been poking at the front door for a week. I only needed a little push. One of your own, as it happens, kindly pulled the lock off the back." He gave a tiny shrug. "That mirror. The one you smashed in the closet. It opened a corridor between the lab and the system. A very narrow corridor, but I'm a thin man."

Archie's stomach turned over.

I did that.

"You're welcome," said William, genially, and walked past him to the pillar of fire. "Now, then. Dr. Ferrara," he bent, and looked into the old man's eyes with the courtesy one extends a patient, "I wonder if I might have a look at your notes."

"Get away from him," said Archie.

"Or what?"

"I'll," his voice cracked, "I'll stop you."

"Will you?" The smile widened. "I rather wish you would. I'd love to see how." William straightened, with the languid grace of a man who has all the time in the world. "You've been so useful, Archie. All of you. I don't think I've ever had better subjects. You've shown me the whole architecture, and a lovely demonstration of what it does to the dying, and the weak points, and the, ah, the personalities."

He tapped his temple.

"I know the lot of you. Your fears. Your wounds. The one thing that makes each of you stop and think. I could have a party with that. I could have the entire group at my feet within the hour." He glanced over his shoulder. "I won't, of course. Not necessarily. But it's nice to have."

Archie lunged.

He hit nothing. William was simply not there, and Archie went through the space where he had been and fell on his hands on the invisible floor. When he looked up, the avatar was a yard away, brushing a sleeve.

"Come, now," said William. "You can't punch an idea."

…

In another place, a long way off, a little man with red hair put his head in his hands.

"He's in," said Otis. "He's in. It's the mirror breach, Dr. Ferrara, it's gone straight through. He's got a live link to the Core. I can see his packets, he's." The little man's voice cracked. "He's going to take Matteo's notes."

Luca had not moved.

He stood in front of the console in the dark control room, with the monitor's glow on his gaunt face and his hands pressed flat to the desk. His eyes were fixed on the screen. They were enormous, unblinking. On it, among the gray tide of rotting filaments, a single point of white light was blinking in the very heart of the lattice, faint and regular.

"That is my brother," said Luca.

"Yes."

"That is his pulse."

"Yes, Doctor."

"He is alive."

"He's, yes. He's alive."

Luca made a sound that Otis would remember for the rest of his life. It was not a sob. It was nothing so decent. It was the noise a man makes when a wall he has leaned his whole weight against for fifteen years suddenly turns out to be a door.

"I can lock William out," he said. "If I am quick. If I cut the line."

"Doctor, if you cut it—"

"If I cut it, I cut the mirror corridor. And the boy in the Core goes dark." He closed his eyes. "That is Archie."

"Yes."

"I can save one."

On the screen, the white light blinked. Beside it, another point, small and warm and golden, steady as a candle.

Matteo, thought Luca. And a man I do not know, and a man I sent.

He opened his eyes. His hand was resting on the switch.

"Give me," he said, "sixty seconds."

…

Archie got to his feet.

He did it slowly, with his hands pressed to his knees, and when he straightened he found that his anger had gone out of him. It had left all at once, like a tide drawing back over mud. In its place was a bleak, clear, absolutely cold sense of exactly where he stood.

I broke the mirror, he thought. I did it for rage. And rage opened a hole, and this is what came through.

Matteo, on the floor, was fading. Archie could see it. The silver light was pulling out of his skin in thin bright threads, drifting up to the cables. His lips were bluish. His head had begun to droop. If the lattice failed, if William's intrusion ate any further, the keeper would go with it, and all five Spaces would go dark. Elena. Thomas. Gregor. Sera. Every friendly face he had met. Every stranger. Every faceless soul in a backward city who had learned, an hour ago, to smile.

There were two doors in the room.

The first was William. William was here. William's mind, his actual consciousness, was lit like a lamp in the lattice, and the system had a place in it for a keeper. A keeper must be a mind. A keeper must stay. If Archie, with Matteo's last strength, could take the man by the throat of his own code and pin him to the pillar, he could set the Guardian rule on him like a collar. William would hold the Core. Matteo would go free. The lattice would heal, and the bridge would stand, and the world's most patient predator would spend eternity as the pier that held the span.

It would be so easy.

It would be so just.

And it would be a kind of murder. A living, thinking man, locked into the dark forever, with a hundred thousand years to think about what he had done. Archie felt it in his stomach, the weight of that. He felt it the way he had felt the funeral director's hand.

The second door was a bridge.

It was a gray one, a quarter-mile away, with a girl at the end of it who had not looked back. She was in the world above, in the sunless light, with a pendant on her breast that beat in time with her heart. He could leave all this. He could turn and go, and run across the dead city until his chest burned, and put the notebook in her hands, and say, I was wrong. He could tell her everything.

But the lattice was dying. And Matteo with it.

And William was smiling.

"Well?" said the thin voice at his shoulder, delighted. "What will it be, Mr. Moran? I'm all ears."
