They didn't get a week.
Two days after Emberwatch, the Hall Stone woke Kairn up.
Not with a sound.
With a pressure.
He sat bolt upright in the narrow cot, heart already pounding, sure for a moment that the King had decided to skip patience and just tear the sky open over the hall.
Lysa's hand snapped to his wrist before he could fling ash on instinct.
"What?" she whispered.
"The stone's humming," he said. "Louder."
She frowned.
"That's not how sleep is supposed to work," she said.
"It is for us," he said.
They found Yselle and the ward-mage already in the stone room, both barefoot, both looking like they'd thrown on whatever garments were closest. The Hall Stone glowed faintly, the lines in it pulsing like a slow heartbeat.
Cale shuffled in behind them with a candle stuck in one hand and his pen still in the other.
"It woke you too?" he rasped.
"Yes," Kairn said.
The ward-mage nodded at the Stone.
"It felt the thread tighten in the night," he said. "Like someone had put more weight on a rope."
Kairn didn't need to ask which rope.
He stepped forward.
"Touch it," Yselle said.
He did.
This time he was ready.
The rush of expanded sight still hit him like stepping into cold water, but he rode it instead of flailing.
Roads.
Wards.
Villages.
The scar Emberwatch had been.
And Greenfold.
The forest-heart glowed brighter now.
Where Emberwatch had been a point of wrongness under stone, Greenfold was something else—a knot where two songs fought.
The world's old forest-music thrummed there, deep and slow.
Over it, trying to wrap and choke, the King's thread tightened.
He wasn't just anchoring.
He was squeezing.
Kairn pulled his hand back.
"Greenfold next," he said. "He's pressing there hardest now."
Yselle's mouth went grim.
"I guessed as much when the Stone hymned itself awake," she said. "Forest guardian going bad is nightmare enough without giving your king a finger in its roots."
"The guardian's not gone yet," Kairn said. "Just… half-smothered."
"Then we pull," Lysa said.
She looked at Yselle.
"You said you don't walk into Greenfold without an invitation," she said. "How do we knock loud enough to matter without getting our teeth turned into mushrooms?"
Cale snorted.
"Forest spirits don't answer to us," he said. "We mark their borders, they leave our roads mostly alone, we don't cut their favorite trees for firewood. That's the agreement."
"Not good enough anymore," Yselle said. "If its roots are being sung wrong, we can't pretend the line on the map keeps that away from our hall."
She looked at Kairn.
"How does your king get in?" she asked. "At Emberwatch, he pushed into old stones. Here, it's a living thing."
"He listens," Kairn said. "He finds whatever the forest spirit fears. Fire. Axes. Forgetting. Crowds. He promises to keep those away. Then he asks for a little slack on the roots as payment."
Lysa's lips thinned.
"Classic," she said. "Abuser logic."
Kairn nodded.
"The more it bargains with him, the more of his pattern gets into its song," he said. "He doesn't have a full hand on it yet. But if we give him weeks instead of days…"
"He'll have a leash on every tree within a day's walk," Cale finished.
Yselle pushed away from the Stone.
"All right," she said. "Emberwatch was ours. Greenfold isn't. We can't walk in there barking orders and swinging steel without making whatever lives there hate us more than it hates your king. So we walk softer. Fewer bodies. Better eyes."
She looked between Barra and Kairn.
"You're going," she said. "Both of you. Lysa. Fen. Kids, yes, but they stay behind the first person who hears a leaf think wrong. Bone-thing, if it promises not to snack on anything that talks."
"I make no such—" the bone-walker started from the doorway, then subsided under four nearly identical glares. "Fine. I will be polite," it muttered.
The ward-mage tapped his staff.
"I'll walk as far as the last marker," he said. "My wards don't sit well under Greenfold's canopy. Better I hold the Hall while you're gone."
Cale scratched a new line on the edge of the map.
"Trail in," he muttered. "Old shrine. Fox stone. Path bends. Then trees start."
Kselle nodded.
"You'll leave at noon," she said. "Give the Stone time to settle and me time to tell people why I'm letting you march toward yet another place we told ourselves we'd never have to rescue."
Kairn swallowed a smile.
"You love your job," he said.
"I love that we have roads to argue about," she said. "Go eat something. You look like Emberwatch fell on you."
"It did," Lysa said.
"Then eat two things," Yselle said.
They did.
Breakfast was thick porridge and leftover stew, eaten standing in the yard while horses were saddled.
Tam tried to hide yawns in his bowl.
Sia watched the gate with the tight, bright look she got when she knew danger was ahead and couldn't decide if she wanted to run toward it or away.
Mar threaded and re-threaded a bit of string between his fingers, expression shut.
Kairn took it from him gently and looped it around the boy's wrist.
"Don't strangle yourself before the forest can try," he said.
Mar frowned, then snorted.
"Fine," he said.
Barra swung into his saddle with the air of a man whose life had become "ride out, come back, repeat."
"Ever been to Greenfold before?" he asked Kairn as they rode through the gate.
"No," Kairn said. "We had forests. None of them had opinions loud enough to hear."
"Greenfold does," Barra said. "You'll understand what I mean when we're under the leaves."
The road south of the hall curved, then angled toward a darker smudge on the horizon.
Trees.
At first just scattered, then thicker, taller, crowns knitting into a line.
The air cooled as they rode.
Cale hadn't lied about the markers.
At a certain point, the road's edges sprouted carved stones—low, squat things half-sunk into earth. Each had a simple fox scratched onto one side, nose pointed toward the trees.
Sia leaned sideways in her saddle as they passed the first.
"Why foxes?" she asked.
"Greenfold's favorite shape, when it wants to watch without arguing," Barra said. "Don't feed them if they're too friendly. You don't want that kind of debt."
The bone-walker perked up.
"They will have very small bones," it said wistfully.
"Do not eat the forest's spies," Lysa said.
"You never let me have any fun," the bone-walker complained.
The closer they got, the thicker the smell of leaf and loam and something else—older, like wet stone and the taste of the air before a storm.
Kairn's Brand buzzed, but differently than it had at Emberwatch.
There, wrongness had sat like a stain.
Here, there was so much *right* that the their king's wrong thread felt thinner by contrast.
"Here," Barra said, reining in.
The road ended.
Not gently.
One moment there was packed dirt flanked by fox-stones.
The next, the way ahead was a wall of trunks and undergrowth so dense it might as well have been masonry.
Between two of the closest trees, someone—or something—had tied a scrap of cloth to a low branch.
Green, faded almost to gray.
Yselle's mark, once.
"Last step," Barra said. "Beyond this, we're guests whether we want to be or not."
Kairn dismounted.
So did everyone else.
The horses shifted, eyes rolling, not keen on the tree-wall.
Mire stayed with them.
"So I keep the exit warm," she said. "Fine by me."
"You don't want to meet mushrooms with teeth?" Fen asked.
"Not today," she said.
Barra slid a hand into his sash and pulled out a small object—a tiny wooden token carved in the shape of a road marked with a single line.
He hung it on the same branch as Yselle's old cloth.
"Roadkeepers," he said quietly. "Walking in. We remember the old bargains. We're here because something else doesn't."
He stepped back.
The air shifted.
Kairn felt it.
Not wind.
Attention.
The tree-wall remained.
Then a gap appeared.
Not like doors opening.
More like trunks and branches that had always been just so now made space in a way his eyes couldn't quite track.
Where there had been thicket, there was suddenly a narrow, leaf-strewn path.
"Satisfying," Fen murmured.
Barra glanced at Kairn.
"You'll feel a weight when you step," he warned. "Greenfold doesn't like feet that don't belong. It'll be heavier for you."
"Because I carry someone else's pattern," Kairn said.
"Because you carry several," Barra said dryly.
Kairn couldn't argue.
He took the first step.
The forest pressed.
Not physically.
It felt like a hand on his head, testing, turning his face this way and that.
Who are you?
What do you bring?
What do you take?
He didn't fight it.
He just walked.
Lysa slipped in at his side.
Her beat shifted to match the new rhythm—slower, broader, like roots drinking.
Da… dum… da… dum…
The pressure eased a fraction.
The kids came next, then Fen, then Barra, then the bone-walker at the rear.
The forest closed behind them.
The light changed.
Under Greenfold's canopy, day was green-gold and dappled, shafts of sun spearing down where branches parted. The air was wet and cool on Kairn's skin, full of the smells of rot and life layered over each other.
Every sound was louder.
Leaves whispering.
Distant bird calls.
The creak of branches.
His own breath.
And under all of it, a low, constant hum.
Not words.
Feeling.
Alive.
Kairn reached out with **Web Map**.
He did it carefully, like touching a wild animal's flank with an open hand.
The King's thread was here.
No doubt.
It wound like a thin, bright line through the under-canopy, draped over branches, snared in moss, tugging toward deeper dark.
But the forest's own lines were thicker.
Older.
The King's presence here felt less like a tower and more like mold creeping onto old bark.
"He's not strong here yet," Kairn murmured.
"Feels pretty strong to my skin," Fen said quietly.
"Not him," Kairn said. "Greenfold."
He could feel the spirit.
Not as a person, not yet.
More like an ocean under his feet, every tree a wave.
It was old.
It had opinions.
It was also… afraid.
Kairn slowed.
The path under his boots curved without his consent, bending them deeper.
"We're not choosing the way, are we," Lysa said.
"No," he said.
"Comforting," she said.
Time got slippery.
They walked.
Moss underfoot, soft and springy.
Roots arching like ribs.
Once, a fox watched them from a fallen log, eyes bright, tail flicking. It cocked its head, sniffed, then turned and vanished between ferns.
"Spy," Fen whispered.
"Be polite," Barra whispered back.
After a while, Kairn realized the King's thread wasn't just ahead.
It was whispering along the path's edges.
Faint.
Almost inaudible.
He heard memories in it.
Someone chopping wood and apologizing to a tree.
Someone else cursing the rain.
Someone whispering, "I wish no one ever found this place again."
The King loved wishes like that.
He chewed on them.
He whispered back.
*No one will. I can make it so. Just let me hold your roots.*
Kairn's teeth ground.
"Don't listen," he said under his breath.
"Who?" Tam asked.
"Any of you," Kairn said. "If you hear anything promising easy road or quiet forever, it's him. Not the forest."
"How do we know the difference?" Sia hissed.
"The forest feels heavy," Kairn said. "Like moss and stone and rain. He feels… polished. Too smooth. Like a song you can't get out of your head."
"That description is rude to songs," Lysa muttered.
The path dipped.
The hum underfoot grew louder.
They stepped into a clearing.
It wasn't big.
Just a space where the trees had pulled back enough to let more light spear through.
In the center stood a stone.
It was waist-high, gray, and smooth with age.
Moss grew in the cracks.
Someone had carved a fox on it, long, long ago.
Around its base lay offerings.
Old ones—faded ribbons, a chipped cup, a rusted knife.
New ones—fresh flowers, a bundle of herbs, a child's wooden toy.
And wrapped around it, faint and clinging, was the King's thread.
Not yet a full net.
But enough to show interest.
Kairn stopped at the edge of the clearing.
"Shrine," Barra said softly.
"Fox stone," Cale had called it.
Greenfold's front porch.
Lysa's fingers tightened on his sleeve.
"Do we knock?" she asked.
"I think we already did," Kairn said.
He stepped forward.
The air thickened.
The hum underfoot rose.
His Brand flared without his say-so, reacting to the sheer amount of *presence*.
He forced it down.
He wasn't here to burn the forest.
He was here to talk.
"Greenfold," he said quietly. "We need to speak."
Nothing answered in words.
Instead, the clearing filled with light.
Not bright.
Not blinding.
It was as if every leaf around them suddenly decided to catch and hold the sun a fraction more, then pour that into the air.
A shape stepped from behind the stone.
It was a fox.
And then it wasn't.
It was a woman.
Her hair was leaf-dark, her eyes fox-bright amber, her limbs too light, as if she were made of twigs and tension. Moss clung to her bare feet. Vines twined around her wrists.
She wore a cloak of overlapping leaves that did not rustle.
She smelled of wet earth and rain on bark.
The kids froze.
Fen swallowed.
Barra bowed his head.
"Greenfold," he said.
The spirit's gaze slid over him with mild acknowledgement, then fixed on Kairn.
She tilted her head.
"You smell wrong," she said.
Her voice was like wind in branches—soft, but with sharp edges.
"Yes," Kairn said. "I'm working on it."
"You carry three songs that are not mine," she said. "One is of teeth. One is of nothing. One is of words written in air."
"The teeth are a friend," Kairn said. "The nothing is a tool. The words are an infection I'm killing."
Her lips curled, not quite a smile.
"You bit," she said. "I felt that. Far away. You hurt the one who whispers of chains."
"Yes," he said.
"Now he is whispering at my roots," she said.
Her eyes narrowed.
"You brought him," she added.
He did not flinch.
"Yes," he said. "I broke his toys. He followed. He is trying to find me by pushing into any place he can."
She stepped closer.
The moss under her feet didn't bend.
It grew.
"Why should I not kill you," she asked, "and tear your pieces into my soil so he loses his scent?"
The King's thread throbbed, delighted by the threat.
It loved when its enemies turned on each other.
Lysa's beat sharpened.
Da-dum.
Da-dum.
Kairn met Greenfold's eyes.
"Because he already knows you," he said. "If you kill me, he will still be here. You'll just have given him the satisfaction of watching us do his work."
Her head cocked.
The leaves around the clearing rustled, though no wind blew.
"You are very sure," she said.
"I've watched him long enough," Kairn said. "He doesn't stop until something stops him. He is using your fear of axes and fire and forgetting to slide under your bark. I know his patterns. I broke one of his roots at a stone fort already. I can cut the thread he has here too."
"You think you can pull him out of my heart," she said.
"I think I can bite him where he's chewing on you," Kairn said. "And I think you can help push."
She studied him.
Her gaze moved over his chest—where the Brand sat, unseen.
Over his hands.
Over Lysa.
"You are not a tree," she said. "You are not a stone. You are a moving thing. You die quickly. You make promises even faster. Why should I trust you? Your kind cut my sisters and burned my sons."
Barra flinched.
"Some of us," he said hoarsely. "Not all. We mark your borders now for a reason."
Greenfold didn't look at him.
She kept her eyes on Kairn.
"You brought him," she repeated.
"Yes," he said. "And I am here to help pull him back out before he roots deeper. If you don't trust me, trust that he hates me more than he hates you. Every time I bite him, he takes his eyes off you to try to swat me."
She considered that.
Her head tilted.
Leaves rustled louder.
The King's thread pulsed in irritation.
It didn't like being discussed as if it were a fox at the edge of a henhouse.
"You burned a piece of him under stones," she said slowly. "I felt that. Like something cut off a root that had wandered too far into my shade."
"Yes," he said.
"That hurt me," she said.
He blinked.
"I didn't mean—" he started.
She cut him off with a sharp flick of her fingers.
"Not much," she said. "Like tearing ivy off bark. Necessary. Painful. It left a line. You will not touch my heart with your nothing."
"The Null," he realized.
It had unmade part of the Seed so thoroughly that the absence had grazed her awareness too.
"I can use teeth instead," he said. "And your own sap."
Lysa stared at him.
"That's not a phrase I ever wanted to hear," she muttered.
Greenfold watched him.
"You would take my song into your fight," she said.
"If you allow it," he said. "Not as a chain. As a shield. As something he doesn't know how to sing."
"You will carry my rhythm," she said. "You will be a walking root."
Her eyes narrowed.
"And if you fall with it into his mouth?" she asked.
"Then he chokes," Kairn said.
Lysa hissed under her breath.
"You're not allowed to throw away your throat for a metaphor," she said.
Kairn didn't look at her.
He kept his eyes on Greenfold.
"I can't promise I won't die," he said. "I can promise that if I do, it won't be in a way that makes it easier for him to eat this world."
Greenfold watched him for a very long time.
The forest held its breath.
Finally, she reached down.
She touched the fox stone.
Moss crawled away from her fingers.
When she lifted her hand, a smear of green light clung to her palm, sticky as sap.
She stepped close enough that Kairn could feel the cold damp of her presence.
"Give me your hand," she said.
He did.
She smeared the sap-light across his palm.
It sank into his skin.
Cold.
Warm.
Alive.
It raced up his arm, into his chest, threading itself through the edges of his Brand, through the engine's hum, through the dragon's coils.
For a heartbeat, everything inside him snarled and pushed.
Then something settled.
The forest's rhythm, deep and slow, joined his.
Da… dum.
Roots drinking.
Leaves breathing.
The King's thread recoiled, as if it had tried to climb a tree and found the bark covered in thorns.
"You will feel my boundaries now," Greenfold said. "You will know when he has stepped where he should not among my roots. You will not cut with nothing. You will not burn more than you must. You will bite and call me, and I will push with you."
Kairn swallowed.
He hadn't realized how much tension he'd been holding until the forest's weight slid into place.
"Deal," he said.
She glanced at Lysa.
"And you," she said. "You play in his patterns. You twist his neat lines. You break his beats. I like that."
Lysa blinked.
"… thank you?" she said.
Greenfold reached out and booped her lightly on the forehead with one twig-thin finger.
Lysa's System flickered in Kairn's ash-eye—just for a heartbeat.
New options.
New modifiers.
"Your songs will not echo where I do not want them to," Greenfold said. "I will hide you when you drum for him."
Lysa's eyes widened.
"That's… going to be rude," she said, a grin tugging at her mouth.
"Good," Greenfold said.
She stepped back.
The light in the clearing dimmed a fraction.
"I will not walk this road for you," she said. "You are small things with short lives. This is your fight. But I will not let him wrap my heart while you gnaw at his toes."
Her gaze flicked once to the kids.
"Keep them from cutting my young ones for fun," she added. "I will not be patient."
"They won't," Kairn said quickly.
Tam nodded so hard his teeth clicked.
Sia's hand had already moved away from the nearest interesting branch.
Mar tucked his string away.
Greenfold inclined her head—once to Barra, once to Kairn, once to Lysa.
Then she stepped behind the stone and was gone.
The hum underfoot stayed.
The King's thread still wound deeper.
But now, wrapped through Kairn's Brand, there was something else.
A root.
A rhythm.
A promise between a moving thing and something that had outlived empires.
Barra exhaled, long and low.
"You just made a bargain with a forest," he said.
"Yes," Kairn said.
Fen rubbed a hand over his face.
"We're collecting patrons like some people collect stamps," he muttered.
Lysa's fingers tapped a new pattern against her leg, thoughtful.
"Teeth, nothing, words, and now trees," she said. "We're going to be very annoying to kill."
Kairn smiled, small and sharp.
"Good," he said.
He turned his head, following the tug of the King's thread and the answering push of Greenfold's new weight inside him.
"Deeper," he said. "Where he's got his teeth in."
The path at the far side of the clearing shifted.
Opened.
The forest hummed.
They walked on.
