The southern approach smelled different now. Three months ago the air there had carried nothing but dust and the mineral tang of barren clay. Today the wind off the ridge brought something green, wet, the sweetness of new growth mixing with old emptiness in a way that hadn't figured itself out yet.
Essa crested the ridge at a gallop and pulled up hard, hooves scattering soil that had been dead grey a month ago and was now closer to brown. Young mare, raw copper coat, scar on her left flank from the battle. She was breathing hard and talking before she'd fully stopped.
"Single figure, coming from the south — on foot, no horse, no cart, I watched it for twenty minutes, it hasn't stopped once, Korr, twenty minutes on the road in full sun, it just keeps—"
"On foot," Korr said. He set down the inventory ledger. "That's what you said. How big?"
"Big. Taller than you." Essa's ears were pinned forward, still tracking something she couldn't see anymore. "It's not a person. I mean it walks like one but it — it's not. The way it moves, the way it doesn't—" She stopped herself, shook her head. "Sorry. You had to see it."
Sera was leaning against the inner gate, arms crossed. A centaur child had drawn on the wall behind her with charcoal — a wobbly circle, might've been the sun or a rock or a face. Someone had started erasing it and given up halfway.
"Two hundred miles south is Veylan's territory," Sera said.
"Demons live a long time," Korr said. He drummed his fingers against his thigh — three beats, pause, three beats. "Perimeter holds position. Funnel it through the thorn corridor. Sera, you're with me."
The demon stood seven feet. Maybe more. Limbs with the elongated proportions of something built for reaching. Grey-blue skin, narrow face, two eyes that were black through and through. It wore a long coat buttoned to the throat, boots made for human feet that didn't fit, a satchel on one shoulder. The clothes themselves were the strangest part. Demons, in Korr's limited experience, didn't bother with clothes.
It stopped at the thorn vine perimeter.
"I am Nethras." The voice was too even. Not flat — controlled, like someone who'd rehearsed the words in a language that wasn't their first. "I have walked from the Southern Reach to speak with whoever leads this place. I am told that is not a simple question."
"Depends on who's asking," Korr said from the wall.
"Then it depends on who answers." A pause. The demon didn't blink. "May I come in?"
Sera's hand was on her sword. The thorn vines shifted along the perimeter. Nethras looked at them, and its expression didn't change, but something in its posture did — a slight settling, the way a person shifts weight when they recognize a specific kind of danger.
"Those will not harm me. I am carrying no weapons. You may verify this."
"How do we know you're not lying?"
"You do not." An insect crawled from the collar of its coat, waved its antennae at the air, disappeared again. "I have walked alone and unarmed through territory where things would eat me if they could. Your vines are not the most dangerous thing between here and the Southern Reach. If Lord Veylan wished to send a threat, there are faster methods than one demon in an ill-fitting coat."
Sera made a sound that wasn't quite a laugh. Korr glanced at her. She shook her head — don't ask.
"Open the corridor," Korr said. "Search it. Everything."
Two villagers went through the satchel and coat with the thoroughness of people who'd been through a siege. Dried meat. Waterskin. A wooden tube sealed at both ends. A book bound in something that wasn't leather, the pages thin and stiff, the text in a script no one recognized. No weapons. Nethras watched the search without comment. When they finished it repacked everything — each item placed back exactly where it had been, the same orientation, the same fold — and looked at Korr.
"Thank you. I understand the need. I would do the same."
They sat in the common hall. The room smelled of wood smoke and bread and the green undertone that had settled into the village's air over the past weeks. Korr took the wall-side seat. Sera beside him. Nethras across the table, long legs folded beneath it in a way that shouldn't have worked but did.
A serving girl brought water and bread. She set them down without looking at the demon's face. Her hand was steady but she was gone fast, footsteps audibly quicker on the way out, and the door swung shut behind her with more force than necessary. The bread was still warm. Nobody touched it.
Old Garrett was in the corner, working on a chair. The same chair he'd been working on for three days — the backrest kept splitting along a grain that wouldn't cooperate, and he'd refused to replace the piece because the grain was good everywhere else and he wasn't going to let one bad section waste a whole board. His hammer went tap-tap-tap in the silence after the serving girl left. Nobody told him to stop. Nobody told him to leave. He was part of the room the way the table was part of the room.
Nethras ate a piece of bread. It watched its own hands while it did — studied them, the way you'd study someone else's hands when you were borrowing them.
"You are wondering why a demon walked through the sun to speak to you."
"I'm wondering why you're still talking instead of answering questions." Korr's voice was flat. "Who sent you, what do they want, and what happens if I don't like the answer."
Nethras set down the bread. "Lord Veylan. Sovereign of the Southern Reach. He has ruled for four hundred years. In that time he has expanded his territory once, and only because the territory in question attacked first. He does not want your land or your tree." It placed the wooden tube on the table. "What he wants is information about the dungeon beneath this village."
Silence. Garrett's hammer stopped.
"The entity you call the Rootmind sealed a dungeon below this place. That entity was then sealed by—" Nethras's black eyes moved toward the open doorway, where the tree's canopy spread across the sky beyond the rooftops. "—by whatever is inside your tree now. Lord Veylan has known about the entity for three centuries. He has been studying it for most of that time. What he does not know is what else is down there. The dungeon was not empty before the entity arrived. We have reason to believe things were left behind when it was sealed."
"Reason?" Sera said.
"Tunnel systems. The entity came from the south — from beneath the Southern Reach, three hundred years ago. It moved through rock and soil and left tunnels our surveyors still cannot fully map. We tracked it to the Barrens boundary." Nethras paused. The pause was deliberate, held a beat too long. "Then we lost it. That was before the entity. Before the Rootmind. Before your tree. What was sealed in that dungeon may not have been alone."
The root beneath the table moved. Not much — a quarter inch, maybe less, a slow shift like something adjusting in its sleep. Korr felt it through his boots. Sera felt it. The bread on the table rolled slightly and stopped. Nethras felt it too. Its hands went flat on the table, and it sat very still for a moment, and Korr watched its face for whatever a demon's version of fear looked like. He couldn't find it. But something had changed in the way it held itself — the slight forward lean gone, replaced by a stillness that read as recalculating.
"The network reacted," Nethras said. Its voice was quieter now. Not afraid. Careful. "I will not pretend that doesn't concern me."
"Join the club," Sera said.
"The offer is this." Nethras steadied itself. "Lord Veylan has three hundred years of survey data — incomplete, but more than you possess. Our engineers know the tunnel system. In exchange for access to the dungeon, Veylan provides everything we have learned about the entity, the tunnels, the deep earth beneath this region. Full disclosure."
"And if we say no?"
"Then I walk home. That is not a threat. It is simply what happens." Nethras stood. The chair scraped. Garrett looked up from his chair-back, hammer frozen, stared at the demon for a long time, and then went back to work. The tap-tap-tap resumed. "I will remain at the way-stop three miles south for seven days. After that, I return and report that you declined. Lord Veylan will not be pleased, but he will not retaliate. Retaliation is inefficient when the alternative is patience."
It moved toward the door. Then stopped.
"There is one thing more." It didn't turn around. "Veylan's scholars believe the entity was fleeing something when it came north. They do not know what. If they are correct, then what it was fleeing may still exist. Deeper. Older. Waiting for the seals above it to fail." It turned its head. Just enough to show its profile against the doorway. "You are sitting on top of something that has been asleep for a very long time. I do not think it will sleep much longer."
It walked out. The door stayed open. Nobody moved to close it.
Garrett's hammer went tap-tap-tap. Someone outside was calling a child in for dinner. The bread on the table was going stale.
Sera exhaled. "So."
"So."
"A demon just told us our dungeon might have more monsters in it, and it was polite about it."
"It was very polite." Korr picked up the wooden tube. Lighter than it looked, sealed with dark resin that smelled faintly of sulfur. He turned it over in his hands. "I want Oswin to look at this. And the shaman."
"And Chris."
"The tree reacted. That's—" Korr stopped. He turned the tube again. "That's what we've got. A reaction. Not an answer."
He tucked the tube under his arm and walked out. The afternoon light was warm. A centaur foal bolted across the courtyard, chasing something invisible, and crashed into a stack of empty crates. The crates went over with a clatter that echoed off the walls. Someone shouted. The foal kept running.
Korr didn't look up at the canopy.
