Chapter 12 What He Owes
They left Duveth's shop without opening the folded paper. Not because Caius didn't want to, because Duveth had said wait until you are somewhere safe and the street outside a blacksmith's shop in a city where someone had already placed a bounty on Renne did not qualify.
The paper sat in Caius's awareness the whole walk, a weight that had nothing to do with its size.
Renne led them to a different part of Ashfen. Narrower streets, quieter, the kind of district that existed in every city because cities always developed spaces that the main traffic forgot about. She stopped at a building that looked abandoned from the outside and was merely empty on the inside, a storage structure whose original function had been replaced by the city's growth.
She checked it, came back out and nodded. They went in. The floor was stone. No furniture, one window, high up, letting in a rectangle of Aethoria's gold afternoon light. Renne sat against the wall with her knees up and her blade across them. Caius sat across from her. Neither of them spoke for a moment.
"You want to know about the fourteen." Renne whispered
"Yes," Caius said. "If you'll tell me."
She looked at the window. Not avoiding him, just finding the right place to put her eyes while she did this.
"Sera," she said. "She was the first one I watched go. Two years in, she was level 41, trying to push into the mid tiers, hit the threshold during a dungeon run." She paused. "Just gone. Between one second and the next. The rest of her party stood there looking at the space she left."
Caius listened.
"Tomek. He was a scholar, spent four years mapping the System's architecture, looking for exit conditions. Got erased six months after he told me he thought he was getting close." There was a pause. "Makes more sense now."
She went through all fourteen. Each one a name, a detail, a moment. She did not cry. She did not soften her voice or look for sympathy. She delivered them the way someone delivers a report, because the report was all she had left that honored them and she was not going to waste it on emotion that helped nobody.
Caius listened to every name. He did not say sorry. He knew she didn't want that, sorry was what people said when they needed to feel better about something they couldn't fix, and Renne was not interested in making anyone feel better. She was interested in what came next.
When she finished, the room was quiet. He looked at the floor and thought about Sera, who he had never met, and Tomek, who had spent four years trying to find a way out of something Caius had built. He thought about twelve other names he had just heard for the first and probably not the last time.
"I'm going to find the Root. Understand what it's building toward. And stop it." Caius said.
She looked at him.
"Not because I think I can," he said. "I don't know if I can, I don't have enough information yet to know if it's even possible." He paused. "But it has to be tried and I'm the only person in this world who has the architecture knowledge to try it." He paused again. "So I'm going to."
She held his gaze for a moment. Reading him the way she read everything, looking for the gap between what someone said and what they meant. She didn't find one. He could see that too.
"Okay," she said.
Just that. Not you can do it or I believe in you. Okay, direct and clean, the response of someone who had decided to attach themselves to a direction and was now asking for the practical details.
"What do you need?" she said.
He appreciated that more than he could have explained.
"More fragments," he said. "The Nullwalker at eleven percent is not enough to do anything serious. Null Step misfires forty percent of the time. The false signature projection cost me three percent integrity just holding it for two seconds." He shook his head. "I need more of the class restored. Which means more corrupted zones. More deleted data."
"How many zones are in the Surface Tier?"
"I designed six. But the log file suggests there may be more that were added without my knowledge." He paused. "Which means I can't rely on my own memory of the layout. I need to scan for them."
"With what?"
"Seam Read, one of the Nullwalker's skills. At eleven percent it barely functions but it should be enough to detect zone anomalies in the immediate area." He looked at her. "It will take time. And every time I use my abilities there's a risk of triggering another Node."
She nodded slowly, working through it. "The maintenance windows," she said. "The System runs lighter at certain hours. Less active processes, less Node activity."
He looked at her. "You know the maintenance schedule?"
"I've been in this world for six years." She said it without pride. Just fact. "You learn the patterns. Players who have been here longer than me have mapped the System's daily cycles in detail. There are four windows. The longest is at dawn, about forty minutes where Node response time drops significantly."
He almost smiled. "You've been running your own version of system analysis."
"I've been surviving." She looked at him steadily. "Same thing, different name."
He pulled up the Nullwalker's internal architecture in his vision, examining the fragment's structure the way he examined code. Looking for the next piece, the next angle, the thing he hadn't tried yet.
He had been looking at it as a power source. A broken class to be rebuilt. He had not been looking at it as a data container.
He went deeper. Past the skill trees, past the class identity architecture. Into the raw data underneath, the layer where the fragment existed before it was anything as organized as a class, when it was just compressed information waiting for a context to make it meaningful.
He found something. Small and dense. Buried under three layers of corrupted compression, almost invisible against the noise of the damaged data around it. Not a skill or a class mechanic.
Coordinates. A location, encoded in the fragment's base data, placed there deliberately, the same way you hide a note inside a book. Not on any page. Tucked between the binding and the cover, for the person who knew to look there.
He read the coordinates. He cross-referenced them against his memory of the Surface Tier's layout. Every zone, every landmark, every terrain feature he had personally designed across four years of development.
The coordinates pointed to a location he did not recognize. Caius checked again. He had designed every inch of the Surface Tier. He had signed off on every zone file, every terrain patch, every scripted landmark. The Surface Tier was the area he knew best, the foundation of the game, the first thing built and the most thoroughly documented.
The coordinates pointed to somewhere that did not exist in any build he had ever shipped.
"Renne," he said.
She looked up from where she had been studying the window.
"The Nullwalker fragment," he said. "It's not just a class."
"What do you mean?"
"It contains a map." He looked at her. "Buried in the data. Coordinates to a location in the Surface Tier." He paused. "A location I didn't design."
She sat forward. "Someone put it there."
"Yes."
"In a fragment from a deleted build. Before launch."
"Yes."
She was quiet for a second. "The person who left the data chip with Duveth. The first ERROR entity." She looked at him carefully. "They left you a path."
"Or someone left me a trap."
"Or both," she said.
He looked at the coordinates sitting in his vision. At the location that shouldn't exist in a world he had built from the ground up. At the gap in his own knowledge of his own creation.
Someone had built something in his world that he didn't know about and they had left directions.
He folded the coordinates into the Nullwalker's active data and stood up.
"Dawn window," he said. "How long until dawn?"
Renne looked at the light through the high window and calculated.
"Four hours," she said.
"Then we have four hours." He looked at the door. At the city beyond it. At everything that was moving in this world that he didn't yet understand. "Tell me everything you know about the Surface Tier's eastern edge."
She stood. Picked up her blade and ooked at him with the expression she wore when she had decided something and was simply executing the decision.
"Start walking," she said. "I'll talk on the way.”
