IM AN ORC?

Rin finished the first version of the model four days after Zree decoded the last of the sky records.

She came to the map room in the early morning with the notebook and the look of someone who had been working through the night and was not going to mention it. She put the notebook on the table next to the map and opened it to the model page — a grid of the territory’s thin places against the seasonal markers, the rate-of-change data plotted, the predictions written in Rin’s precise hand.

Ruk looked at it. Then he called Zree.

Zree came in and looked at the model with the amber eyes, the sound-mapping attention shifted to the page, the quality of someone reading a document with the same focused precision she brought to reading the marsh. She was quiet for a long time.

"The boundary-thin periods," she said. "You’ve identified three."

"Late autumn, early spring, and midsummer," Rin said. "The rate-of-change data shows the growing thin places widening fastest in those periods. The stable thin places show small but measurable frequency variation at the same times."

"The sky records show the same three periods," Zree said. "The autumn stars, the spring stars, the summer stars — those were the times the Greythorn shamanesses were most active, most watchful." She paused. "My teacher called them the listening seasons."

"The model predicts that any thin place currently growing will widen by approximately fifteen percent during each boundary-thin period," Rin said. "And that any thin place currently stable will show a frequency variation of less than five percent — not enough to cause problems, but measurable."

"The Old Anchor will show the five percent variation," Zree said. "If the model is correct."

"Yes," Rin said. "And we’re currently three weeks from the midsummer boundary-thin period." She looked at Ruk. "If we go to the Old Anchor now and assess it, we have a baseline. Then we assess it again at midsummer peak and see if the variation matches the prediction."

Ruk looked at the model. At the grid, the predictions, the three weeks of waiting that Rin was describing. He thought about what Zree had said — I don’t like waiting. He thought about the Old Anchor, the most stable thin place in the eastern lowland, six generations of stability.

"We go now for the baseline," he said. "We come back at midsummer peak for the test."

Rin nodded. "I’ll come with you."

Zree looked at her. "You’ve never done fieldwork."

"I’ve done fieldwork," Rin said. "I document the watch rotation. I’ve been to the northern range thin places twice."

"The marsh is different from the northern range," Zree said.

"I know," Rin said. "That’s why I want to come." She paused. "The model is only as good as the field data. I need to see the Old Anchor myself to understand what I’m modeling."

Zree looked at her for a moment. The amber eyes, the assessment. Then she looked at Ruk.

"She comes," Ruk said.

Zree looked at Rin. "You follow my lead in the marsh," she said. "The terrain is difficult and I know it. You don’t move without telling me where you’re going."

"Agreed," Rin said. She already had the field notebook ready — smaller than the map room notebook, designed for carrying.

They left the next morning, the four of them — Ruk, Zree, Sorn, Rin — heading south and east toward the lowland. Sorn had been to the marsh before and moved through the transition from highland to lowland with the ease of someone who had learned the terrain. Rin had not, and she moved through it with the careful attention of someone who was learning it in real time, the notebook out, the observations going in.

Zree watched Rin with the amber eyes. Not impatiently — with the quality of someone who was assessing a new variable, deciding how to account for it. Rin moved carefully but she moved well, the scholar’s precision applied to the physical terrain the way it was applied to the page.

"You’re mapping as you go," Zree said.

"The terrain features," Rin said. "The transition from highland to lowland — the elevation change, the soil change, the vegetation change. I want to know if the boundary sense changes with the terrain the way the hollow note frequency changes."

"It does," Ruk said. "The boundary is thicker in the highland. Thinner in the lowland. The marsh is the thinnest."

"By how much," Rin said.

Ruk thought about it. About the quality of the boundary sense in different terrain, the way the thin places felt different in the highland versus the lowland versus the marsh. "In the highland the thin places are distinct — sharp edges, clear boundaries between the thin place and the surrounding seam. In the lowland the edges are softer. In the marsh the thin places blend into the general thinness of the boundary — harder to distinguish individual thin places from the overall quality of the seam."

Rin was writing. "The boundary thinness is a property of the terrain, not just of the individual thin places," she said.

"Yes," Ruk said.

"Then the seasonal variation might be a variation in the terrain’s baseline thinness," she said. "Not just in the individual thin places. The whole boundary thins during the listening seasons, and the individual thin places thin with it."

Zree stopped walking. She turned and looked at Rin. "Say that again," she said.

Rin said it again.

Zree was quiet for a moment. The amber eyes, the quality of someone who had just heard something that reorganized a large amount of what they knew. "My teacher said the hollow notes breathed with the seasons," she said. "I thought she meant the individual hollow notes. She might have meant the whole boundary."

"If the whole boundary thins seasonally," Sorn said, "then the growing thin places are growing because the baseline is dropping, not because something is pushing at them from the other side."

"Or both," Ruk said. "The baseline drops, the thin places are more vulnerable, the things on the other side push harder because the resistance is lower."

They stood in the lowland grassland and thought about this. About the model, the seasonal variation, the whole boundary thinning rather than individual thin places growing. About what that meant for the work.

"It means the listening seasons are when the whole territory is vulnerable," Rin said. "Not just the growing thin places. All of them."

"The watch rotation needs to be heavier during the listening seasons," Sorn said.

"Yes," Ruk said.

Rin was writing fast. "I need to update the model," she said. "The predictions change if the baseline thinness is the variable rather than the individual thin place growth rate." She paused. "The Old Anchor assessment is still useful — it gives us the baseline variation. But the interpretation changes."

"Update it when we get back," Ruk said. "Let’s get the baseline first."

They reached the eastern lowland by midday and the marsh by late afternoon, the reed beds and the water and the sound of the living marsh around them. Rin stopped at the marsh’s edge and looked at it with the scholar’s attention — the terrain, the vegetation, the quality of the light on the water. She was quiet for a moment.

"It’s alive," she said. Not a scholarly observation — just the quality of someone who had not been to the marsh before and was encountering it for the first time.

"Yes," Zree said. There was something in her voice when she said it — not warmth exactly, but the quality of someone who heard the right response to the marsh and recognized it.

Zree led them to the Old Anchor. It was in the northern section of the marsh, away from the dead stand, in a part of the reed beds where the ground was firm enough to stand on and the water was shallow. The reeds were dense here, the air thick with the marsh smell, the birds loud in the late afternoon.

Ruk felt the Old Anchor before he saw the location. The boundary sense found it immediately — not the sharp hollow quality of a growing thin place, not the drained cold of the dead stand. Something older, more settled, the quality of a thin place that had been there so long it had become part of the territory’s character. The seam was thin here, genuinely thin, but stable — not growing, not being pushed at, just present. The Old Anchor.

Zree stopped at the edge of a small clearing in the reeds. "Here," she said.

Ruk stood at the clearing’s edge and felt the Old Anchor through the boundary sense. The settled quality, the stability, the thin place that had been here for six generations of shamanesses and would be here for six more. He reached for the frequency of it, the rate of change — and found what Rin’s model had predicted. A small variation, the frequency slightly lower than the baseline, the boundary marginally thinner than it would be at the non-listening-season times of year.

"I feel the variation," he said.

Zree reached with the sound method. The low frequency, the mapping reach. She was quiet for a long moment. "The hollow note is slightly deeper than the last time I assessed it," she said. "Three weeks ago. The frequency has dropped." She paused. "We’re approaching the midsummer boundary-thin period. The model is correct — the Old Anchor is already showing the variation."

Rin was writing. "The variation has already begun three weeks before the peak," she said. "The boundary-thin period is longer than I modeled — it’s not a sharp peak, it’s a gradual deepening and then a gradual recovery."

"How long," Sorn said.

"I need the midsummer peak data to know," Rin said. "But if the variation has already started three weeks out—" She was calculating. "The full boundary-thin period might be six to eight weeks. Not a single peak."

Ruk thought about that. About six to eight weeks of the whole boundary thinning, the growing thin places more vulnerable, the things on the other side pushing harder. About the watch rotation, the clan’s capacity, the territory’s size.

"Six to eight weeks twice a year," he said. "The spring and autumn listening seasons."

"And midsummer," Rin said. "Three boundary-thin periods a year, six to eight weeks each." She paused. "That’s roughly half the year when the territory is at elevated risk."

They were quiet with that.

Zree looked at the Old Anchor. At the clearing in the reeds, the thin place that had been here for six generations. "My grandmother’s grandmother knew this," she said. "The listening seasons were half the year. That’s why the Greythorn shamanesses were always active — there was always a listening season coming or going." She paused. "I thought we were unusually busy. We were just doing the work the territory required."

"Half the year at elevated risk," Sorn said. "The watch rotation needs to double during those periods."

"We don’t have the people to double the watch rotation," Ruk said.

"We will," Sorn said. "Brek is almost ready to work independently. Rin can do the assessment work if not the physical closing. Zree adds the eastern lowland capacity." He paused. "In six months we’ll have the people."

Ruk looked at him. At the shadow-walker, the quiet competence, the quality of someone who had been thinking about the capacity problem and had already worked through it. "Six months," he said.

"If we train consistently," Sorn said.

Ruk looked at the Old Anchor. At the clearing, the thin place, the marsh around it. He thought about the work — the territory, the thin places, the listening seasons, the long record being built. He thought about six months of training and the capacity that would exist at the end of it.

"Then we train consistently," he said.

They assessed the Old Anchor fully — Ruk with the boundary sense, Zree with the sound method, Rin documenting everything. The baseline data went into the field notebook in detail: the frequency, the rate of variation, the size, the stability, the quality of the seam at this location. The most stable thin place in the territory, the Old Anchor, the baseline against which everything else would be measured.

They were heading back toward the marsh’s edge when Sorn stopped.

He had the shadow-walker’s quality of stopping — not dramatically, just a stillness, the movement ending, the awareness extending. He was looking south.

"Someone’s coming," he said.

Ruk felt for it through the boundary sense. Not a thin place problem — a person, moving fast through the lowland grassland, coming from the south. The quality of someone who had been running.

The messenger reached them at the marsh’s edge twenty minutes later. A young man, one of the settlement runners from the network Ruk had been building since Millhaven — the people in the outlying settlements who knew to send word if something was wrong with the boundary.

He was breathing hard. He had been running for most of a day.

"Thornfield," he said. "South settlement. Two days south of here." He paused to breathe. "Something is draining it. The livestock first, then the crops. Three people found unconscious in the south field — alive but wrong, the life-quality gone out of them." He looked at Ruk. "The headwoman says it started four days ago. It’s getting worse."

Ruk looked at Zree. She was already reading the direction — the sound-mapping attention on the south, the reach for the frequencies in that direction. Her face had the focused quality of someone who was finding something.

"There’s a hollow note south of here," she said. "I’ve never assessed it — it’s outside the Greythorn territory. But I can feel it from here." She paused. "It’s not small."

Ruk felt for it through the boundary sense. South, the direction the messenger had come from. The hollow quality, distant but present, the drained quality of a thin place that was actively pulling the life-quality out of the area around it.

Not a growing thin place. An open one.

Something had already come through.

"How many people in Thornfield," he said.

"Sixty," the messenger said. "Maybe seventy."

Ruk looked at Sorn. At Zree. At Rin, who had the field notebook open and was already writing.

"We go now," he said.

They moved south through the lowland at a pace that was not quite running but close to it. The messenger kept up — he had the lean endurance of someone who had been a runner his whole life, the kind of person who could cover ground all day without complaint. Rin kept up too, the field notebook put away, her attention on the terrain and the pace.

Zree moved with the sound-mapping attention running continuously, the reach extending south, tracking the hollow note as they closed the distance. She said nothing but Ruk could read the quality of her attention — the focused watchfulness of someone who was reading a problem as they approached it, building the picture before they arrived.

Sorn moved at Ruk’s left shoulder, the shadow-walker’s quiet presence, the awareness extending in all directions. He had the quality of someone who was comfortable moving fast toward a problem — not eager, not afraid, just present and ready.

The lowland grassland gave way to the southern scrubland as the light began to fade, the terrain changing, the vegetation thicker and lower, the ground drier. Ruk felt the hollow note growing stronger as they moved south — the drained quality, the life-pulling cold of an open thin place. Not the sharp hollow of a growing thin place that hadn’t broken through. Something that had already opened.

They reached Thornfield as the last light was going.

The settlement was a cluster of stone buildings around a central well, the kind of place that had been here for generations, the buildings worn smooth with use. It should have had the quality of an evening settlement — fires going, the smell of food, the sounds of people settling in for the night.

It had none of that.

The fires were small and low, as if the people tending them didn’t have the energy to build them properly. The settlement had the quality of a place that had been slowly drained — not destroyed, not attacked, but depleted. The livestock in the pen by the eastern building stood with their heads down, not eating, not moving. The crops in the south field were visible even in the fading light — the wrong color, the life-quality gone out of them, the stalks standing but hollow.

The headwoman met them at the settlement’s edge. She was a solid woman in her fifties, the kind of person who had run a settlement through hard seasons and harder years, and she had the quality of someone who was frightened but was not going to show it in front of her people. She looked at Ruk — at the size of him, the orc, the boundary sense visible in the quality of his attention — and then at Zree, and then at the others.

"You’re the ones who closed the western forest," she said.

"Yes," Ruk said.

"The south field," she said. "That’s where it started. The south field and then the livestock and then—" She stopped. "Three of my people. They went to check the south field two days ago and they didn’t come back. We found them at the field’s edge. Alive. But—"

"I know," Ruk said. "The life-quality gone out of them."

She looked at him. "Can you fix it."

"The three people — I don’t know," he said. "The thing doing it — yes."

She looked at him for a moment. Then she nodded, the headwoman’s quality of accepting the honest answer and moving forward. "What do you need."

"Keep everyone inside tonight," he said. "Away from the south field. No one goes near it until morning." He paused. "And I need to see the three people who were drained."

She took them to the building where the three were being kept. They were lying on pallets, breathing, eyes open but unfocused — the quality of people whose bodies were present but whose life-quality had been pulled thin. Ruk stood at the doorway and felt for them through the boundary sense. The life-thread in each of them was present but attenuated, stretched thin, the way a rope looked when it had been pulled almost to breaking.

"They’re not gone," he said. "The thread is still there. If we close the thin place, the pulling stops. They may recover."

"May," the headwoman said.

"I don’t know how long it’s been pulling," he said. "The longer it pulls, the harder the recovery." He looked at her. "We close it at dawn. That’s the best I can tell you."

She looked at the three people on the pallets. At the unfocused eyes, the shallow breathing. Then she looked at Ruk. "Dawn," she said.

They set up in the building nearest the south field — not in the field itself, not until morning. Ruk sat with the boundary sense extended toward the south field, reading the open thin place, building the picture of what they were dealing with. Zree sat across from him, the sound-mapping attention running, reading the same thing from a different direction.

The open thin place was in the center of the south field. It was not large — not the size of the dead stand thin place, not the size of the marsh’s growing hollow notes. But it was open, which was different from growing. A growing thin place was a weakness in the seam, a place where the boundary was thinning. An open thin place was a hole — the seam had broken through, and whatever was on the other side was reaching through the hole and pulling.

"It’s been open for at least four days," Zree said. "The hollow note frequency is stable — it opened and then stabilized at the open state. It’s not growing larger. It’s just pulling."

"What’s on the other side," Sorn said.

"I can’t tell from here," Ruk said. "The boundary sense reads the seam, not what’s beyond it." He paused. "But the pulling quality — the way it’s draining the life-quality from the field and the livestock and the people — that’s a specific kind of thing. Not a creature that came through. Something that’s reaching through the hole from the other side."

"A feeder," Zree said. "The Greythorn records have three accounts of feeders. Things that don’t come through — they stay on the other side and reach through the opening to pull what they need." She paused. "The accounts say they’re harder to deal with than things that come through. You can’t fight something that’s on the other side of the seam."

"You close the hole," Ruk said.

"Yes," she said. "But the feeder will resist the closing. It knows the hole is being closed and it pulls harder." She paused. "The accounts say two of the three Greythorn shamanesses who tried to close a feeder’s hole were drained in the attempt."

The building was quiet.

Rin was writing. Not the field notebook — the other one, the model notebook, the documentation. Her face had the focused quality of someone who was frightened and was managing it by doing the work.

"The combined method," Ruk said. "Your resonance stabilizes the seam while I close it. The feeder can’t pull at both of us simultaneously."

Zree looked at him. The amber eyes, the assessment. "That’s the theory," she said. "We’ve never tested it against a feeder."

"We tested it against the dead stand," he said.

"The dead stand didn’t have a feeder on the other side actively resisting the closing," she said.

"No," he said. "But the principle is the same." He paused. "The resonance holds the seam stable. The feeder can pull at the boundary thread all it wants — if the seam is stable, the thread holds. I close the hole from the inside while you hold the outside."

She looked at him for a long moment. The amber eyes, the calculation. "If the feeder pulls hard enough, the resonance breaks," she said. "And then both of us are exposed."

"Then we don’t let the resonance break," he said.

She looked at him. Then she looked at the south field, the darkness beyond the building’s window, the open thin place somewhere out there in the dark. She looked at it with the quality of someone who had been doing this work her whole life and understood exactly what the risk was.

"At dawn," she said.

"At dawn," he said.

Sorn took the first watch. Rin updated the model. Ruk sat with the boundary sense extended and read the open thin place through the night, building the picture, understanding the feeder’s rhythm — the way it pulled in slow steady draws, the quality of its reach, the strength of it. He was learning it the way he had learned the dead stand’s creature before closing it — not to fight it, but to understand it well enough to work around it.

Zree slept. The quality of someone who had learned to sleep before difficult work — not because she wasn’t concerned, but because she understood that the work required everything she had and she would need to be rested to give it.

The night passed. The lowland was quiet around the settlement, the grassland and the scrubland and the darkness. The open thin place pulled steadily in the south field, the life-quality draining slowly from the crops and the livestock and the three people on the pallets.

When the sky began to lighten in the east, Ruk stood up.

Zree was already awake.

They looked at each other across the building. The quality of two people who had done difficult work together before and were about to do it again.

"Ready," she said.

"Ready," he said.

They went out into the grey pre-dawn light and walked toward the south field.
