The days in the valley have a rhythm. Not the sharp, jagged rhythm of Kingsbridge—the bells, the shouts, the crack of Essence from practicing children. A softer rhythm. The creak of the cart. The clink of Liana's healing tools. The thunk of Kael's wooden sword against a post.
Atreus does not know what to do with softness.
He wakes before dawn. The habit is carved into him—wake early, before the guards come, before the screaming starts. He lies still on the straw mattress, listening. The house breathes around him. Aeros's slow, deep breathing from the room below. Liana's softer, quicker breaths beside him. Kael's small, whistling snores from the next cot.
He waits for the violence. It does not come.
On the third morning, he gets up. He dresses in the clothes Liana left for him—a clean tunic, too large, and trousers held up with a rope. He goes to the window. The valley is grey with the perpetual twilight of the Belt. The three suns are smears of gold, blue, and violet behind a thin layer of cloud. The river glints. The goats are already moving in their pen, restless.
He goes downstairs.
Liana is in the kitchen, stirring a pot over the hearth. Her back is to him. Her Brand—the small, silver Cinder's mark on her forearms—glows faintly as she channels a thread of Solace into the pot. Not for the food. For the water. Purification.
"You're up early," she says without turning. "Did you sleep?"
Atreus does not answer. He does not know how to answer questions about sleep. Sleep is not rest. Sleep is falling into the dark where his mother's face waits.
Liana turns. She looks at him. The same careful, kind look. Not pity. Assessment.
"Come," she says. "Sit. Eat. Then we will talk."
He sits. He eats. The porridge is warm, sweetened with a drizzle of honey. He eats too fast, as always, and his stomach cramps. He does not stop.
Kael appears halfway through breakfast, rubbing his eyes, his dark hair sticking up in every direction. He is still in his sleeping tunic. His wooden sword is in his hand. It is never far.
"You're eating," Kael says, as if this is remarkable. "Good. Eating is good. Mama says eating is the first step to being alive."
"Kael," Liana says.
"What? It's true." He climbs onto the bench across from Atreus. His left hand—the one with the small silver crack—rests on the table. He sees Atreus looking at it. He grins.
"It got bigger," he says. "See? It was just here before. Now it's here." He traces a line from his thumb to his wrist. The crack is still small—barely the length of a fingernail—but Kael's pride in it is enormous.
"It's not the size," Liana says, setting a bowl of porridge in front of Kael. "It's the control."
"I have control," Kael says. "Watch." He holds up his hand. The crack pulses. A tiny wisp of gold light flickers. It lasts two seconds this time—longer than before. Then it fades.
Kael looks at Atreus, waiting for approval.
Atreus does not know what to say. He has no Brand. No light. No flicker. He looks at his own smooth hands under the table.
"It's good," he says. The words feel strange in his mouth. He has not offered praise in a long time.
Kael's grin widens. "I know."
---
After breakfast, Aeros takes Atreus outside. The valley is waking—the goats are bleating, a dog is barking somewhere down the slope, smoke rises from the chimneys of the other houses. Aeros leads him to a flat area behind the barn, where the grass is worn down from use. There are targets nailed to posts—straw bundles wrapped in sacking. A practice ground.
"You cannot channel," Aeros says. "You cannot heal. You cannot throw fire or shatter stone. But you are not helpless."
He draws his knife. It is a simple blade—single-edged, leather-wrapped hilt, a shallow fuller. He flips it in his hand and offers it to Atreus, hilt first.
Atreus stares at it. The last time he held a blade, it was a hoof pick. He was painting a man's throat with it.
"Take it," Aeros says.
Atreus takes it. The weight is different from the hoof pick. Balanced. Meant for killing.
"The first lesson," Aeros says, "is not how to use it. The first lesson is when to use it. A knife is not a weapon. It is a last word. You use it when there are no other words left."
He takes a step back.
"Now. Show me how you stand."
Atreus stands. He does not know how he stands. He just stands.
Aeros studies him. The dark eye moves from Atreus's feet to his shoulders to his hands.
"You are holding your breath," Aeros says. "Stop. You are gripping the knife too hard. Your hand will cramp. Loosen. Let the knife rest."
Atreus loosens. The knife shifts in his grip. It feels less like a tool now. More like something alive.
"Better," Aeros says. "Now. Come at me."
Atreus blinks. "What?"
"Come at me. Try to hit me."
"I don't—"
"The people who want to kill you will not wait for you to be ready. They will not ask if you understand the lesson. They will come. Now. Come at me."
Atreus looks at the knife. He looks at Aeros. The man is unarmed. His Brand is dim. He is just standing there, hands at his sides.
Atreus moves.
He is fast—faster than he expects. The hunger and the running have made him lean, made his muscles wire-tight. He lunges, the knife leading, aiming for Aeros's chest.
Aeros is not there.
He sidesteps. His hand closes around Atreus's wrist. He twists. The knife falls. Atreus's arm is bent behind his back, his face pressed into the grass. The pressure is precise—painful but not damaging.
"Too fast," Aeros says, his voice calm. "You committed to the attack before you knew if it would land. You did not watch my feet. You did not watch my shoulders. You watched the place you wanted the knife to go."
He releases Atreus and steps back.
"Again."
Atreus picks up the knife. His wrist throbs. He wants to cry. He does not cry.
Again. And again. And again.
By midday, he has not touched Aeros once. His body is a map of bruises. His palms are raw. His pride is ash.
But something is happening. The fourth time, he sees Aeros's weight shift before the sidestep. The seventh time, he feints left and goes right—Aeros still avoids him, but there is a pause, a fraction of a second where the man's dark eye widens.
"You learn fast," Aeros says. "That is good. Fear is a teacher. So is pain. But they are cruel teachers. They do not give you the answers. They only show you the questions."
He takes the knife back. He wipes it on his sleeve and sheaths it at his belt.
"Tomorrow, we do it again. And the day after. And the day after. Until you do not need to think. Until your body knows what to do before your mind catches up."
Atreus nods. He is too tired to speak.
---
Kael finds him at the river that evening. Atreus is sitting on a flat rock, his feet in the cold water, watching the light fade. The goats are being herded into the pen. Smoke rises from the chimneys.
Kael sits beside him. He does not say anything. He just sits. His wooden sword is across his lap.
After a long silence, Kael speaks.
"My father says you killed a man."
Atreus stiffens. The cold stone in his gut shifts.
"I don't believe him," Kael says. "Not because I think he's lying. I just think maybe he misunderstood. You're my age. You're small. You don't have a Brand."
Atreus looks at his hands. Smooth. Empty.
"I killed a man," he says. His voice is flat.
Kael is quiet for a moment. Then he nods.
"Was he bad?"
Atreus thinks about Corvin. The wet, ugly smile. The Brand flaring as he took his turn. The way he wiped his hands on a cloth afterward, as if he had just finished a meal.
"Yes," Atreus says.
"Then that's okay," Kael says. "My father says the world is full of bad people. He says sometimes the only way to stop them is to be worse."
Atreus looks at Kael. The boy's face is serious now. The grin is gone.
"Does that scare you?" Atreus asks.
Kael thinks about it. He turns the wooden sword over in his hands.
"Yes," he says. "But not as much as doing nothing."
---
That night, Atreus lies awake again. The house is quiet. The valley is dark. The only light is the faint green-black smear of Dread through the clouds.
He hears Kael's words. Sometimes the only way to stop them is to be worse.
He thinks about the hoof pick. The way it felt going into Corvin's throat. The way the blood sprayed. The way the light went out of the man's eyes.
He should feel guilt. He does not. He feels something else. Something colder.
I could do it again, he thinks. If I had to. I could.
He does not know if this makes him a monster.
He does not know if it matters.
---
The next morning, Aeros is gone.
His cart is still there. The horses are in the barn. But Aeros is not in the house. Liana is calm—too calm. She moves through the morning chores with a practiced stillness that Atreus recognizes. The stillness of someone who is waiting for news.
"Where is he?" Atreus asks.
Liana looks at him. The kind eyes are hard now.
"Crossroads," she says. "The deal with Sera. He went back to finish it."
Atreus feels the cold stone grow heavier.
"Alone?"
"He is always alone," Liana says. "That is what it means to be a Warden."
She turns back to the hearth. Her hands are steady, but Atreus sees the small silver Brand on her forearms pulse—once, twice—a flicker of uncontrolled Essence. Fear.
He does not know what to say. He does not know how to comfort. He has never been comforted.
Kael appears in the doorway. His wooden sword is in his hand. His face is pale.
"Will he come back?" Kael asks.
Liana does not answer.
Crossroads – The Same Morning
Aeros walks alone.
The road to Crossroads is a pale scar through the grey twilight, lined with thornbushes that whisper when the wind blows. He does not hurry. Hurry is a tell. Hurry says I am afraid of what I carry.
He carries the location of the Weeping Field's core. Not a map. A memory. The core is not a thing you can draw. It is a wound that moves, that breathes, that hides from those who seek it. Only a Warden's Brand—tuned to the specific discordance of the Scar—can find it.
He has tuned his Brand for three days. The cracks on his arms ache with the effort. Holding Lament's frequency at the edge of pain, listening for the song of a dying place. He found it. He recorded it in the only way that matters: by burning the resonance into his own flesh.
Now he will trade it to Sera for a route north.
The gates of Crossroads are open. No guards. No walls that matter. The town exists because no one wants it enough to take it. The dregs of the Twilight Belt wash up here—fugitives, debtors, channelers who burned too bright and lost their place in the world. Sera is their queen, not by title but by fear.
He finds her in the same low inn, the same corner table, the same greasy light. She is not alone today. Two men sit behind her—big men, their Brands hidden under tunics, but he can smell the Wrath on them. The sharp, ozone tang of channeled destruction.
"You came back," Sera says. Her purple Brand pulses once, lazy. "I thought you might run. Take the boy. Disappear."
"I don't run," Aeros says. He sits across from her. His hand rests on the table, open. Not a threat. Not a surrender.
"The route," Sera says. "You have it?"
"The core first."
Sera laughs. The sound is dry, like leaves skittering on stone. "You think I trust you, Warden?"
"I think you want the core more than you want to play games. The Weeping Field is spreading. Two villages are already gone. The False King will notice soon. When he does, he will send his Unfading. They will not negotiate. They will burn Crossroads to the ground just to get close to the Scar."
Sera's smile fades. She knows he is right.
"The core," she says. "Prove you have it."
Aeros rolls up his sleeve. The Brand on his forearm is different now—new cracks, thin and raw, arranged in a spiral pattern that seems to move when the light shifts. He presses his palm to the table. The Brand glows. A low hum fills the room, discordant, wrong. The two men behind Sera shift uncomfortably.
"It's in the old watchtower," Aeros says. "Three miles north of the Field's edge. Buried under the foundation. The Scar has been using it as a anchor."
Sera leans forward. Her grey eyes are bright. "How do you know it's still there?"
"Because the Scar is still spreading. If the core had been taken, the Scar would be dying." He pulls his sleeve down. "Now. The route."
Sera reaches into her coat. She pulls out a small, folded map. The parchment is old, brittle, stained with something brown. She slides it across the table.
"The Path of Silent Bones," she says. "Old smugglers' route through the Mourning Pass. The False King's men don't watch it because the Grief-Eaters nest there. You'll need to move at night, when the Grief-Eaters are hunting elsewhere."
"And the boy?"
Sera's smile returns. "I told you. The offer stands. The Disciplined pay well for nulls. They use them as anchors. A null can walk into a Scar without waking it. You know this."
Aeros takes the map. He folds it carefully and tucks it into his shirt.
"The boy is not for sale."
He stands. The two men behind Sera tense, but Sera waves them down.
"You're making a mistake, Warden. The boy will get you killed. Or worse. He'll become something you can't control."
Aeros looks at her. His dark eye is cold.
"Then I will deal with that when it comes."
He walks out. The mud sucks at his boots. The sky is the color of a bruise. He does not look back.
---
The Valley – Three Days Later
Atreus is mending a fence when Kael appears with two wooden swords.
The boy's face is flushed with excitement. His dark hair is even messier than usual, and his tunic is half-untucked. The small silver crack on his hand glows faintly—not from channeling, but from the simple heat of running.
"Father is back," Kael says. "He brought news. And he said we can train together."
Atreus sets down the hammer. His hands are callused now, the skin rough from work and from Aeros's lessons. The bruises have faded to yellow smears. He is still thin, but the hollows in his cheeks have filled slightly. Liana's cooking is simple but steady.
"Train how?" Atreus asks.
Kael holds out one of the wooden swords. It is shorter than his own, lighter, the edges rounded smooth. "Like this. Father says you need to learn to fight someone your own size. And I need to learn to fight someone who doesn't have a Brand."
Atreus takes the sword. The weight is familiar now. Not the hoof pick. Not Aeros's knife. Something in between.
"Where is he?"
"At the practice ground. He's waiting."
They walk together. The valley is quiet. The goats are grazing. A few of the other families—the ones who live in the scattered houses down the slope—are working their small plots of land. A woman with a Cinder's Brand on her neck is coaxing beans from the soil. A man with no Brand at all is chopping wood. The valley is a patchwork of the Branded and the null, living side by side because Aeros has made it safe.
Atreus wonders how long that safety will last.
The practice ground is empty except for Aeros. He stands at the center, arms crossed, his dark eye watching them approach. His Brand is dim, but Atreus notices new cracks on his forearm—thin, raw, still healing. The trade with Sera cost him something.
"You're late," Aeros says.
"We came as fast as we could," Kael says.
"Fast is not the same as early. Early is a choice. Fast is a reaction." He looks at Atreus. "You. Show me your stance."
Atreus plants his feet. He holds the wooden sword in both hands, point forward, elbows slightly bent. His weight is balanced. His breathing is steady.
Aeros nods. "Better. Kael. You."
Kael's stance is different—wider, more aggressive, the sword held in one hand. The small crack on his other hand glows as he channels a thread of Solace into his grip, strengthening it.
"Good," Aeros says. "Now. Fight."
Atreus and Kael look at each other.
"Fight," Aeros repeats. "Not to kill. To learn. Touch your opponent with the blade. First to three touches wins."
Kael grins. "You're going down, null."
Atreus does not smile. He watches Kael's feet. He watches his shoulders.
Kael moves first.
He is fast—faster than Atreus expects. The wooden sword whistles toward Atreus's ribs. Atreus sidesteps, just as Aeros taught him. The blade passes through empty air. Atreus brings his own sword up, not to strike, but to block the follow-up.
Thwack.
Kael's sword hits Atreus's guard. The impact jars his arms. Kael is stronger. The Solace in his grip gives him an edge.
"One," Kael says.
Atreus resets. He watches. Kael's stance is aggressive, but his left side is open. The hand with the Brand—the hand that channels—moves slightly before each attack. A tell.
Kael comes again. Atreus does not sidestep. He drops low, sweeping his sword toward Kael's leading leg. Kael jumps back, off-balance. Atreus lunges forward and taps the wooden blade against Kael's chest.
"One," Atreus says.
Kael's grin widens. "Lucky."
"Again," Aeros says.
They fight. The wooden swords clack and thud. Kael lands two more touches. Atreus lands two more. The score is tied. Both boys are breathing hard, sweat running down their faces.
"Final point," Aeros says. "No rules. Everything you've learned."
Kael charges. His Brand flares brighter than before—a real channel, not just a trickle. The wooden sword in his hand glows faintly gold. He is using Essence to enhance his speed.
Atreus does not try to match him. He cannot. Instead, he does something Aeros never taught him.
He drops his sword.
Kael hesitates. The charge stutters. He is confused. In that moment of confusion, Atreus steps into Kael's reach, grabs the boy's sword hand with both of his, and twists.
Kael yelps. The wooden sword falls. Atreus kicks it away and presses his forearm against Kael's throat—not hard, but firm.
"Touch," Atreus says.
Silence.
Aeros watches. His dark eye is unreadable.
Kael blinks. Then he laughs. "That's cheating!"
"That's surviving," Aeros says. His voice is quiet. "Atreus, you dropped your weapon. Why?"
Atreus releases Kael and steps back. "He was faster. I couldn't beat him with the sword. So I changed the fight."
Aeros nods slowly. "And if he had been trying to kill you? If he had not hesitated?"
Atreus thinks about it. "I would have been dead. But he did hesitate. I saw it. The Brand makes him think he has an advantage. He expected me to try to match him. When I didn't, he didn't know what to do."
Aeros looks at Kael. "He's right. You relied on your Brand. You forgot that a weapon is only as dangerous as the hand that holds it. Atreus has no Brand. So he must be more clever. More patient. More dangerous in the spaces between your power."
Kael's grin fades. He looks at his hands. The small silver crack pulses once, then dims.
"I lost," he says.
"You learned," Aeros says. "That is worth more than a win."
He turns to Atreus.
"You. The trick with the dropped sword. It worked today. Tomorrow, it may not. Do not rely on surprise. Surprise is a one-time gift. After that, your enemy knows you are unpredictable. They will expect the unexpected. Then you must be predictable in ways they do not see."
Atreus nods. He does not fully understand. But he files the words away, in the same drawer where he keeps the memory of the hoof pick and the weight of the shallow grave.
---
That evening, Liana makes a stew with rabbit and wild onions. The four of them sit at the table—Aeros, Liana, Kael, Atreus. The fire crackles. The light of Mourning filters through the shuttered windows, painting the room in shades of violet and grey.
Aeros tells them about Crossroads. Not everything. He leaves out the part about Sera wanting to buy Atreus. But he tells them about the route north, the Path of Silent Bones, the Grief-Eaters that nest there.
"The False King is consolidating," Aeros says. "His Unfading are pushing south. They're looking for something. Not land. Not tribute. Something else."
"What?" Liana asks.
Aeros shakes his head. "I don't know. But Sera mentioned that he has a taste for nulls. He's collecting them. Why would a king collect people with no Brand?"
The table is quiet.
Kael looks at Atreus. His eyes are wide.
Atreus feels the cold stone in his gut. It is not heavy. It is alert. A predator waking from sleep.
"We need to know more," Atreus says. His voice surprises him. It is steady.
Aeros looks at him. "Yes. We do. But we cannot go north yet. The Grief-Eaters are active. We wait for the Mutes to shift. In the meantime—"
"There's the hermit," Liana says.
Everyone looks at her.
"The hermit," Aeros repeats. His voice is flat.
"In the eastern hills. The old man who came to the valley two years ago. He said he was a scholar. He said he knew things about nulls." Liana's hands are folded on the table. The small silver Brand on her forearms glows faintly. "You told me to stay away from him. But if the False King is collecting nulls—"
"He's dangerous," Aeros says. "He's Scar-Touched. Not Disciplined. He's held together by spite and old memories. One wrong word and he'll—"
"He's dying," Liana says. "I saw him last month. He came to the edge of the valley, looking for herbs. His Brand is black now. The corruption is spreading. He won't last the year."
Aeros is silent. His jaw works.
"I'll go," Atreus says.
The table goes quiet again.
"Absolutely not," Aeros says.
"He knows about nulls. You said I need to understand what I am. What I could become." Atreus looks at Aeros. His eyes are steady. "I'm not asking for permission."
Kael shifts beside him. "I'll go too."
"Kael—" Liana begins.
"He's my friend," Kael says. "Friends don't let friends talk to crazy hermits alone."
Atreus looks at Kael. The word friend lands in his chest like a stone dropped into still water. He does not know what to do with it.
Aeros stares at both of them. His dark eye is unreadable. Then he sighs. It is a long, tired sound.
"Three days," he says. "You have three days to find the hermit, talk to him, and come back. Take the eastern trail past the old mill. Do not go near the Scar at the ridge. Do not eat anything he offers you. Do not let him touch you."
He looks at Atreus.
"And do not trust him. He is not your enemy. But he is not your friend. He is a broken thing that remembers what it was like to be whole. That makes him unpredictable."
Atreus nods.
Kael grins. "This is going to be an adventure."
"It's going to be a lesson," Aeros says. "The kind you survive. If you're lucky."
---
The Eastern Trail – Next Morning
The light is the color of old bruises as Atreus and Kael set out. The eastern trail is narrow, overgrown with thornvines that snag at their clothes. Kael walks ahead, his wooden sword in hand, swinging it at the branches. Atreus walks behind, watching the shadows.
The old mill comes into view after an hour. It is a skeleton of blackened timber, the wheel broken and half-sunk into the creek. Aeros said a fire took it ten years ago. A family lived there. They all died. The Scar at the ridge is close enough that the air tastes of rust.
They pass the mill without stopping. The trail climbs. The trees thin out, replaced by twisted bushes with red berries that Kael says are poisonous. Atreus does not ask how he knows. He is learning that Kael knows many things—where the best climbing trees are, which mushrooms are safe to eat, how to tell if a storm-horse is about to kick. The boy's knowledge is practical, earned from years of wandering the valley.
"Have you ever seen a Scar?" Atreus asks.
Kael shakes his head. "Father says I'm too young. He says Scar-creatures can sense Branded children. They like the taste of new light."
Atreus looks at his own smooth hands. "What about nulls?"
"I don't know. He never said." Kael looks back at him. "Why?"
"Because if Scar-creatures can't sense nulls, then I could go where you can't. I could see things you can't."
Kael stops walking. He turns. His face is serious.
"Don't," he says. "Don't go looking for Scars. They're not adventures. They're wounds. You don't poke a wound to see how deep it goes."
Atreus does not answer. He is not sure he agrees.
---
The hermit's shack is at the edge of a small clearing, built from scrap wood and animal hides. Smoke rises from a hole in the roof. The smell is strange—not woodsmoke, but something sharper, like burnt hair and old lightning.
The door is open. Inside, the darkness is thick, almost solid.
"Hello?" Kael calls out.
A voice answers. It is a dry, cracking voice, like old parchment being crumpled.
"Null and Brand. Walking together. How strange. How interesting."
A figure emerges from the darkness. He is old—older than anyone Atreus has ever seen. His skin is the color of ash, pulled tight over bones that seem too sharp. His eyes are pale, almost white, and they do not focus quite right. His Brand is a nightmare.
It covers everything. His face. His neck. His hands. But it is not silver or gold. It is black. The cracks are thick, oozing, and they pulse with a light that has no color—or all colors at once. The corruption Liana spoke of. The Scar-Touched mark.
But his eyes, unfocused as they are, hold something else. Recognition.
"You," the hermit says, looking at Atreus. "I dreamed of you. Three nights ago. A boy with no light, walking through a field of ash. Behind you, a shadow that was not your own."
Atreus feels the cold stone shift.
"What shadow?" he asks.
The hermit smiles. His teeth are yellow, worn down to nubs.
"The First Shade," he says. "It sees you, null. It has been watching you since the moment you picked up the hoof pick."
Kael steps closer to Atreus. His wooden sword is raised.
"Don't," the hermit says. "I won't hurt you. I can't. I'm too old. Too close to the end." He shuffles back into the darkness, gesturing for them to follow. "Come. Sit. I will tell you what I know about nulls. About the False King. About the silence between songs."
Atreus looks at Kael. Kael looks at him.
They step inside.

END OF CHAPTER FOUR
