Chapter 15 What Duveth Guards
Duveth was behind his counter when they walked in. He looked up then at Caius's face. He put down the tool he was holding with the careful deliberateness of someone setting aside one kind of work because another kind was about to begin.
"You used the Seam Read," he said, not a question.
"Yes," Caius said.
"And you saw it."
"Yes."
Duveth nodded slowly, like something he had been waiting for had finally arrived and he was taking a moment to acknowledge that it had come, after everything, after three hundred years, it had actually come.
Renne closed the shop door behind them and stood in front of it. Not blocking it, just present and watchful.
Caius walked to the counter and put both hands flat on it. He looked at Duveth directly.
"What is underneath this building?" he said.
Duveth held his gaze for a long moment, the shop was quiet around them. The forge was cold today, no work running, which Caius suspected was not coincidence.
Then Duveth came around the counter. He crossed to the large workbench against the eastern wall. Heavy thing, solid, bolted to the floor with hardware that looked permanent. He put his hands on its edge and pushed.
It moved without resistance. Smooth and easy. The bolts were fake, or the floor fitting was designed to release, because the bench slid aside like it had been doing exactly this for a very long time, which it had.
Beneath it, a hatch. Cut into the floor with edges too clean for anything rendered in the standard terrain engine. Not carved. Cut, the difference being that carving left traces and this left none. Like someone had simply told the floor to have a door and the floor had agreed.
Renne moved from the door to stand beside Caius. She looked at the hatch, then at Duveth. "How long has that been there?"
"Since before the shop," Duveth said. He crouched and lifted it. No lock or mechanism. Just a hatch that opened when you lifted it because it was built to open when you lifted it and for no other reason. "The shop was built over it. Not the other way around."
Below: a ladder, below the ladder: light. The steady low illumination of something that had been running on minimum power for a very long time and had gotten good at it.
Duveth went down first, Caius followed. Renne came last, pulling the hatch down above her, not closing it fully. Just reducing the gap.
The room at the bottom of the ladder was wrong in a way Caius felt before he understood it. His Seam Read flared the moment his feet hit the floor, the skill screaming at the edges of the space, trying to map something that wasn't mappable because the room existed outside the Surface Tier's zone file entirely.
Null space, the architectural equivalent of a margin. A room written between the lines of the world.
"How is this possible," he said.
"I don't know how it was made," Duveth said from across the room. "Only that it was here when I found it."
The room was small. Stone walls that matched nothing in Aethoria's visual library, a different grammar, older, rawer. And against the far wall, a terminal.
Physical hardware. Real world manufacture, rendered in game the way the data chip had been rendered, the System doing its best with something it had no category for. A screen, a keyboard, cables running into the wall and disappearing into null space. The screen was on.
Caius crossed to it. The code running on the terminal was old. Not old like the corrupted zones were old, degraded and breaking down. Old like something that had been written with enough care that three hundred years hadn't touched it. Clean logic and careful architecture. The kind of code that lasted because the person who wrote it understood that it would need to.
He read the process name on the screen. He read it twice.
"That's impossible," he said quietly.
"What is it?" Renne asked from behind him.
"The original error handler." He reached out and touched the edge of the terminal, not the screen, just the frame, needing to confirm it was real. "I built this. In the first year of development, before we even had a game. Just an architecture." He looked at the screen. "It was supposed to catch System failures before they propagated. Find errors before they became problems. Correct them automatically." He paused. "We replaced it with a newer version before launch. This one was deprecated, removed from every build."
"Apparently not," Renne said.
"Apparently not." He leaned closer. The process was running clean, a steady cycle, doing exactly what it was designed to do. Scanning, finding. Attempting to correct. "It's been running for three hundred years."
"Yes," Duveth said.
Caius turned to look at him. "You've been keeping it running."
"Yes."
"For three hundred years."
"Sixty years after the world began I found this room." Duveth stood with his hands at his sides and his voice steady. "I did not understand what I was looking at immediately. It took time. I had to learn what the terminal was. What the code meant. I had no documentation." He paused. "I had only what I could observe. And what I observed was this. When the handler ran well, the world was more stable. When it struggled, things got worse." He looked at the terminal. "And if it stopped entirely." He paused. "I tested that once. In my second century. I let it run down to see what would happen."
"What happened?" Renne asked.
"The tremors tripled in frequency within two weeks." His voice did not change. "I restarted it immediately. I have not let it stop since."
Caius turned back to the screen. He was reading the handler's output log, scrolling through three centuries of attempted corrections, the system quietly finding errors and trying to fix them, over and over, a program working against a problem that was always bigger than it could solve.
"The corrupted zones," he said.
"Yes," Duveth said.
"The handler generates them." He read the log, understanding building as he went. "It finds corrupted data in the System's architecture and attempts to quarantine it, pulling it out of the live environment and storing it in isolated patches. The corrupted zones are its storage containers." He paused. "Which means every fragment I've been pulling power from."
"Is data the handler quarantined," Duveth finished. "Yes. It has been storing corrupted material for three hundred years, old build data. Deleted content. Anything the System rejected or abandoned." He looked at Caius. "Including deleted classes."
Renne made a small sound. "The Nullwalker fragments."
"The handler quarantined the deletion," Caius said. "When the class was cut from the build, the handler flagged the deleted data as corrupted material and stored it rather than letting it purge fully." He looked at the terminal with something that was not quite wonder and not quite grief. "It saved them. By accident. Because that's what it was built to do. Save things that were being lost."
The room was very quiet.
"So the corrupted zones exist because the handler has been running, and the handler has been running because Duveth kept it alive. And the fragments you've been using to build your power base exist because the handler saved them three hundred years ago." Renne muttered.
"Yes," Caius said.
"And if Duveth hadn't found this room," she said. "If he hadn't kept it running."
"The Root would have accelerated," Duveth said simply. "Without the handler catching System errors and quarantining corrupted data, the System's failures would have fed directly into the Root's accumulation cycle. The count would be finished by now." He looked at Caius. "I did not know that was what I was preventing. Not for a long time. But I knew the tremors responded to the handler's health. So I kept it healthy."
Caius looked at the man. At three hundred years of quiet maintenance in a room that nobody knew existed, running a program he hadn't written for a reason he hadn't fully understood, because the alternative felt wrong and he had learned to trust that feeling.
He opened his mouth, the terminal flickered. Not a normal flicker. A system interrupt, code appearing on the screen that hadn't been there a moment before, writing itself in real time, character by character, with the unhurried pace of something that wanted to be read slowly.
Caius read it as it appeared. Renne moved to his shoulder, she couldn't read the code but she could read his face and she was reading it now, closely, her hand moving to her blade.
Duveth went very still. The message finished writing itself. It sat on the screen in clean text, against the handler's steady output, inserted into the running process like a letter slipped under a door.
“Hello, old program. And hello, Caius. I see you've found my counterweight. I've been meaning to deal with that.”
Nobody spoke. The handler kept running beneath the message, steady and quiet, doing what it had always done, trying to fix a problem too large for it.
Caius looked at the words on the screen, then he looked at Duveth.
Duveth was looking at the terminal with the expression of someone who had been afraid of exactly this moment for a very long time and had known, somewhere underneath everything, that it was always going to come.
"How fast," Caius said quietly, "can you r
un a backup of the handler's core process?"
Duveth moved to the terminal without answering. That was answer enough.
