The plan was simple.
Kael had learned something important in his three weeks of accidental survival in the First Age: simple was the only thing that worked. Complex required resources he didn’t have, expertise nobody here possessed, and time that the Unraveling was actively stealing from everyone.
Simple just required people willing to swing an axe.
"You want us to dig a hole," Davan said.
"Several holes."
"In front of the village."
"Specifically in the path the Thornback uses to approach the village, yes."
Davan looked at him the way a man looks at something he’s decided is both stupid and personally offensive. "We tried digging before. The Ridgeclaw walked around it."
"The Ridgeclaw was smarter." Kael crouched and smoothed out a patch of dirt with his palm. "The Thornback isn’t smart. It hunts by vibration — feel how it moves? Steady rhythm, same path every time. It’s not tracking you. It’s following the noise of the village."
Silence.
He looked up. Thirty-one people were staring at him.
"How do you know that," Seris said. She was standing at the edge of the group, arms crossed, the specific posture of someone who had decided to be skeptical before he’d opened his mouth. She was maybe twenty, lean and dark-eyed and had already saved two children from the Thornback attack by doing something with a sling that Kael was genuinely impressed by. "You’ve been useless for three days and now you know how a Thornback hunts."
"I’ve been observing for three days."
"You’ve been lying in a hut."
"Observing from a hut. It’s a technique."
Mara made a sound behind him.
"The point," Kael continued, standing, "is that it doesn’t adapt. It follows noise, straight line, every time. So we don’t need a hole it can’t walk around. We need a channel." He drew in the dirt. "Treeline here. Village here. We clear a corridor — narrow, deliberately narrow — and line both sides with everything loud we have. Bones, dried wood, anything that cracks underfoot. And at the end of the corridor—"
"The pit," Orin said. The old healer had pushed to the front, peering at the dirt diagram with bright, interested eyes. He was the only person here who looked excited. Kael appreciated that enormously. "You funnel it into the pit."
"Not just a pit. A pit with one side cut steep and one side cut at an angle." He sketched it out. "Steep side faces the approach. The Thornback falls in, tries to climb the steep side — can’t. Tries the angled side — legs can’t get purchase at that width." He paused. "Probably."
"Probably," Davan repeated.
"Eighty percent confident."
"And the other twenty percent?"
"We run."
Davan turned to Mara with the expression of a man lodging a formal complaint with management. Mara was looking at the dirt diagram. Her head was tilted slightly. Kael had learned to read that tilt — it meant she was finding fault with something she didn’t want to find fault with.
"The corridor," she said. "Clearing it means noise. Today. It’ll attract the Thornback before we’re ready."
"Which is why we start from the treeline and work toward the village. If it comes early it follows the noise away from us, not toward."
The tilt changed slightly. That was the it’s actually reasonable but I’m not going to say so yet tilt.
"It’ll take all day," she said.
"Yes."
"We’ll be exhausted by nightfall."
"Also yes."
"And if it doesn’t work—"
"Then we’ve cleared some brush and dug a very large hole and we’re no worse off than this morning." He looked around at the group. "We lost twelve people last month. Nine the month before. The Thornback comes back every three to five days. At current rate—" he stopped himself. They could all do that math already. They were living it. "We need to change something. This is a thing we can change."
The silence was different this time. Not skeptical. Heavier.
Davan broke it. "I’ll need six people on the pit. Ground’s hard here, we’ll lose time if—"
"Eight," Kael said. "Four digging, four rotating out. You’ll keep pace longer."
Davan looked at him.
Kael looked back.
Something shifted in the larger man’s jaw. Not agreement exactly. More like the grudging acknowledgment that the annoying person had made a point.
"Eight," Davan said. "Seris, take four and start the corridor from the northern treeline. Sol—" a pause on the name, deliberate— "you’re with me."
Kael nodded.
Orin fell into step beside him as the group dispersed into motion, the particular urgent energy of people who had decided to do something with their fear rather than sit in it.
"The way you described the Thornback’s hunting behavior," Orin said, quiet enough for just the two of them. "I’ve watched those creatures for years. I never thought of it that way. Vibration. Not sight. Not smell." He paused. "Where did you learn that?"
"I read a lot."
"We have no books."
"I read a lot before."
Orin was quiet for a moment. Then: "You’re different since you hit your head."
"People keep saying that."
"Because it keeps being true." The old healer’s voice was gentle. Not accusatory. Just — observant. He reminded Kael, painfully, of the kind of teacher who actually pays attention. "You move differently. You think differently. You paused yesterday before eating the morning meal — just for a moment, like you’d forgotten what it was." A beat. "Sol never paused for anything."
Kael kept his eyes forward. "Maybe I’m growing as a person."
"Maybe," Orin said pleasantly, and said nothing else.
The digging took all day.
It was brutal, unglamorous work — breaking hard earth with tools that were optimistic at best, dragging soil away in woven baskets, arguing about depth and width and angle while the sun moved overhead and everyone’s hands bled a little. Kael worked alongside them and learned things about his new body: it was stronger than he’d expected, had calluses in exactly the places that mattered, and apparently Sol had at some point made a decision to never, ever stop.
His lungs burned. His shoulders screamed. He kept working.
Around midday Seris appeared at the pit edge, looked down at the progress, and said nothing. Which from her, Kael was beginning to understand, was practically a compliment.
Around late afternoon a child came sprinting from the village lookout.
"It’s coming."
Everyone froze.
Then looked at Kael.
He became suddenly and acutely aware that thirty people were looking at him with an expression that could best be described as you said eighty percent.
"Corridor," he said, keeping his voice level. "Everyone off the approach line. Get to the treeline flanks. Quiet."
They moved. Quickly. The weeks of fear had made them fast at following orders — the question was always just whose orders. Mara got people positioned. Davan, without being asked, took the rear flank with the three best warriors and a look on his face that said he was absolutely prepared to die proving Kael wrong.
Kael pressed himself against a tree at the corridor’s edge and waited.
He heard it before he saw it.
The grinding rhythm — that wet, steady crunch of something massive moving through undergrowth without caring what it crushed. Getting closer. Then the treeline at the corridor’s far end shuddered, and it stepped through.
He’d seen it before, from the hut, at distance. Distance was better.
The Thornback was roughly the size of a large van, low-slung and armored in ridged plates the color of dried blood. Its head was small relative to its body — sensory organs, not weapons. The legs were what killed you, six of them, each ending in something between a claw and a blade.
It stopped at the corridor entrance.
Kael stopped breathing.
The creature’s head moved. Slow, searching arcs. Looking for — no. Feeling for. Vibration. Noise.
The corridor was still. Everyone was still.
Then a branch settled somewhere on the village side — the natural creak of wood in afternoon heat — and the Thornback’s entire body oriented toward it like a compass finding north.
It moved into the corridor.
The noise traps worked better than Kael had expected. Dry bones cracked under its legs. Stacked deadwood clattered. It registered none of it as threat — it was just ambient noise, the sound of the village ahead — and so it kept moving, steady and rhythmic and completely unaware.
Right up until it wasn’t moving anymore.
The pit was six feet deep, eight feet wide, with the far wall cut at seventy degrees and the near wall cut almost vertical. The Thornback’s front legs found nothing and it went in front-first, the back legs scrambling for purchase on the crumbling near edge, and then it was in and the sound it made was enormous — crashing, scrabbling, furious.
Not dead. They’d known it probably wouldn’t be dead.
But contained.
Kael walked to the pit edge and looked down.
The Thornback looked up at him. Its sensory organs contracted and expanded. The legs worked against the steep walls and found nothing to grip.
"Yeah," he said. "That’s the steep side. That one’s not going to work for you."
It made a sound like grinding stone.
"The other side’s also not great." He crouched. "You’re going to be here for a while. We’re going to figure out something more permanent. I’d apologize but you did eat twelve of us."
Someone appeared beside him. He expected Mara.
It was Davan.
The big man looked into the pit for a long time. His jaw was doing the thing. His hands were loose at his sides — not fists, which Kael had learned to track as a meaningful distinction.
"The angle on the far wall," Davan said finally.
"Seventy degrees. Steep enough to prevent grip, shallow enough that the fall doesn’t kill it outright and trigger a panic response that—"
"Where did you learn that."
"I—"
"Not the ’I read a lot’ answer." Davan looked at him. Hard, direct, the look of a man who had survived this long by accurately reading threats. "The real answer."
Kael held the gaze.
Thirty-one people were alive right now who had woken up this morning uncertain they’d see nightfall. Orin was already examining the corridor noise traps with barely-concealed intellectual delight. Seris was standing at the pit’s edge with an expression that wasn’t quite wonder but was in the same neighborhood. The children were being allowed to look at the trapped creature from a safe distance, which he’d learned mattered — letting children see the monster contained did something important for the psychology of a group that had been running for six months.
He didn’t know how to explain any of that to Davan. The reasoning, the instinct, the half-remembered fragments of psychology and animal behavior and engineering that had assembled themselves into a functional trap in a single afternoon.
"I’m figuring things out as I go," he said. "Same as everyone here."
Davan looked at him for another long moment.
"The pit needs a cover," he said finally. "Or something else comes along and falls in and we waste it."
Kael blinked. "...That’s a good point."
"I know." Davan walked away.
That night, around a fire that felt different than the previous nights’ fires — warmer somehow, or maybe just less frightened — Mara sat beside Kael and handed him a portion of the evening meal without comment.
He ate.
She watched the fire.
"Twenty-seven days ago," she said, "Sol fell off the eastern ridge trying to retrieve an arrow. Hit his head on the way down. We thought he was going to die." A pause. "He didn’t. But I’ve been watching you since then and I think maybe something else did."
Kael was quiet.
"I don’t know what you are," Mara said. Not unkindly. "But you built something today that kept us alive. So whatever answer you give me, understand that I’m asking out of trust, not fear."
He looked at the fire for a long time.
"I’m someone who woke up somewhere unfamiliar," he said carefully, "with knowledge that doesn’t belong here, in a body that isn’t mine, in a time that makes no sense to me." He paused. "And I am doing my absolute best."
The fire crackled.
"That’s honest," Mara said.
"I’ve decided honesty is more efficient."
She was quiet for a moment. Then: "The knowledge that doesn’t belong here. Is there more of it?"
"Considerably more."
"Good." She stood. "We have a lot of problems."
She walked toward the sleeping shelters.
Kael stayed by the fire and felt, somewhere deep in his chest, that low hum shift — just slightly. Like something noticing he was paying attention.
He ignored it.
For now.
Three days later, a trader from the eastern settlements arrived with news: somewhere to the north, a tribe of thirty had apparently trapped a Thornback.
Word was spreading.
It always did.
