He cleared for six hours.
Not continuously — he was learning already that the Vein had a rhythm to it, the same way a pressure system had a rhythm, the same way any sustained output had a natural interval between effort and recovery if you paid attention to it. He pushed for forty minutes, absorbed until the Vein's response dulled slightly at the edges the way a tool dulls when it has been working correctly for a long time, and then he stopped and drank water and sat and let whatever was happening inside him reset.
The first rest, he sat on the dark soil and looked at what he had made.
It was not large. A clearing approximately the size of the communal hall in Ashmore — the hall where the settlement had held its planning meetings and its cold-season meals and the small ceremonies that settlements hold because ceremonies are what distinguish a place where people live from a place where people merely survive. He thought about the hall and then he stopped thinking about it because thinking about the hall led to thinking about the people who had filled it and that led somewhere his body had decided it was not ready to go yet.
He ate a piece of the hardtack from his pack instead. He chewed it methodically. He looked at the soil.
It was doing something.
He had not noticed it immediately — the change was too slow to be dramatic, the kind of change that reveals itself only when you look away and look back. Where the grey had been half an hour ago, the dark soil had a quality of presence that was more than just colour. A faint humidity, as if the earth were breathing out. A smell that was not unpleasant and was not anything he had a name for — mineral and deep and clean in the way that things are clean when they have been thoroughly finished with something that was wrong for them.
He put his hand flat on it again. Still warm. Warmer than before, in fact. Not hot — but undeniably warmer than the ambient temperature and warmer than it had been in the morning.
He thought about what his father had said, once, about materials that had been under sustained pressure. They hold the memory of it, his father had said. Take away the pressure, give them time, they settle back into what they were. But it takes time. The longer the pressure, the longer the settling.
Two hundred years of Blight, he thought. This is going to take some time.
He went back to work.

Osric found a use for himself by midday, which was the specific point at which a man who had been a farmer for forty years and was standing in cleared soil containing trace elements he had never encountered stopped watching and started assessing. He did not ask Flaire's permission. He crouched at the edge of the clearing with the expression of a craftsman evaluating a new material, picked up a handful of the dark soil, compressed it, let it fall through his fingers, and said nothing for long enough that Flaire had completed another absorption cycle and come back to rest before Osric spoke.
"This is going to grow things," Osric said.
"I do not know what," Flaire said.
"Neither do I. But it will grow things. The density is extraordinary." He picked up another handful, brought it close to examine, put it down with the care he would have used on something valuable. "The nitrogen content alone — whatever the Blight does to soil, it does not drain it. It puts something in. Something else, something wrong, something that makes standard crops fail. But underneath that, this is some of the richest substrate I have seen."
"If you can get past whatever makes it wrong."
Osric looked at him. "Can you get past it?"
Flaire thought about the absorption process. About how the Vein took the Blight energy and transformed it without destroying what the energy was interacting with — not erasure, conversion. The mineral compounds the Blight produced would remain. The specific quality of wrongness would leave. What remained would be dark soil with an unusual mineral profile, warm with some slow internal process, and whatever Osric's forty years told him it would eventually do.
"I think so," he said. "In stages. It may not look like normal soil for a while."
"Things that grow in it may not look like normal crops for a while."
"Probably."
Osric sat down on the earth with the slow authority of a man whose knees had informed him that this was happening now whether he approved or not. He looked at the clearing. He looked at the grey walls still pressing from three sides. He looked at Flaire in the way that people look at the single mechanism keeping a fragile system functional — not with worship, not with fear, just with the sober awareness of a dependency they had not chosen.
"How long can you do this?" he said.
"I do not know."
"Best estimate."
Flaire thought about the dulling at the edges of the Vein's response. About how long it took to recover. About the sustainable rate versus maximum output, and the difference between the two. "As long as I pace it correctly," he said. "Days. Weeks, maybe. I do not have a ceiling yet."
"Do you have a floor? A point where you stop being able to?"
He thought about the incursion. About the moment when the Blight energy had reached for the parts of him that were still functioning and the Vein had answered it with the specific readiness of something that had not been waiting for permission, only for occasion. He had not run out then. He had not been close to running out. But the incursion had been a crisis and crises made different demands than sustained work.
"I do not know," he said again.
Osric nodded, as if I do not know were precisely the correct answer to file under honest uncertainties that required monitoring. "Then we keep track," he said. "You tell me when it feels different. I will watch for signs you might not notice from the inside."
Flaire looked at him. "You are volunteering to monitor my capability state."
"I am volunteering to pay attention," Osric said. "Same thing. Farmers do it with everything. Soil, weather, animals, whatever." He picked up another piece of soil and put it back down. "Things that are working correctly give you specific signals. So do things that are starting to fail. You learn to read them if you are paying attention."
Flaire thought about his father saying almost exactly the same thing, with different vocabulary, about steam pressure systems.
"All right," he said.
He went back to work.

Tam spent the afternoon doing something that was either play or investigation, and the distinction probably did not matter because in an eight-year-old they were the same activity under different names. She walked the perimeter of the clearing — inside the safe edge, not past it — pressing her fingertips against the grey walls at irregular intervals with the concentrated attention of someone taking measurements in a system they do not yet have instruments for. She did not ask to go closer to the grey than the clearing's edge. She did not ask Flaire to explain what he was doing. She observed, and occasionally she crouched and looked at something in the soil, and once she stood completely still for almost three minutes with her eyes closed and her head tilted slightly, the posture of someone listening for something at the edge of audibility.
Flaire noticed. He absorbed another section, recovered, and during the recovery he sat near her.
"What are you listening for?" he said.
She opened her eyes. She was not startled — she had known he was there. "It still talks," she said. "The grey. From further in. It is different than last night."
He looked at the grey wall nearest them. It had the same colourless density it always had, the same indifferent fullness. "Different how?"
She considered this with the seriousness of someone trying to translate between two languages they were not yet fluent in. "Last night it was loud," she said. "Now it is — " She paused. "Not quiet. But further away. Like when you move a sound source and the sound gets smaller even though it is still the same sound."
He looked at her.
"You feel it move when I clear," he said.
"Yes."
He did not know what to do with this information yet. He filed it carefully, in the place reserved for things that were clearly important and not yet categorisable, and he went back to the third absorption cycle of the afternoon.
By evening the clearing was the size of three communal halls.
He stopped when Wren announced, with the specificity of someone estimating by long experience, that the light had approximately forty minutes left and that continuing past the light seemed like a risk that did not have a proportionate reward. He did not argue. He sat on the dark warm earth in the middle of what he had made and looked at it.
Three halls. In six hours, with recovery intervals. He did the arithmetic: if the rate held, if the Vein's response maintained its current consistency, if he paced it correctly — and pacing it correctly was the variable he could not yet fully model — then in five days he could clear enough ground to make a question out of what had been only a fact.
The question was not yet one he had language for. But it lived somewhere below his sternum, adjacent to where the Vein lived, in the same approximate space where his father's method had always operated: understand the system, identify the failure point.
Fix it.
