Chapter 51: Eon
They didn’t speak right away.
Kori stood with her heels set in the carved groove, knives low, and the ruin breathed around them with a weird cold like it had opinions about midnight. Dust hung lazy. Pebbles like they were trying out a new trick. "Don’t move" she said again - not a warning so much as a promise.
Raizen didn’t. The twins at his back carried a thrum so small it lived under hearing, more suggestion than sound. He couldn’t feel the ruin, not the way the air had changed around Kori, but the steel knew a thing he didn’t.
The particles along Kori’s knives calmed to hairline fireflies. The motes slowed. Pebbles lost interest and settled with soft, embarrassed clicks. She lifted her eyes to him and the tease was gone. Something else had come to the surface - the look a cliff gives the sea when it’s time to discuss boundaries.
"Lesson" she said. "Not a lecture."
He huffed and didn’t risk a smile.
"Eon" she continued. "People like to dress it up. They call it mystery, spirit, a thousand names that make them sound wise. It’s simpler and ruder than that. It’s what lives between your heartbeat and your intention. It’s the yes that turns a thought into a thing. Humans make a lot of it. Luminite sings a lot of it. Together, they argue and then agree."
She rolled one knife in her palm. The white along its spine moved like breath.
"Luminite weapons don’t just hit harder. They’re translators. You feed them Eon. They hand it back as something the world will actually obey. Staff users send it outward. Armor keeps it in. Blades sharpen it until it hurts. If you’re smart, you pick the translator that fits the way you already speak."
She tipped her chin at his back. "Your twins want a say."
He slipped both blades free. Dark steel took the ruin’s thin light and kept it. The thrum in the metal tightened by a hair as if it had felt the air change and decided to stand up straighter.
"You hear it?" she asked.
"No."
"Good. If you did, you’d be a liar." She stepped out of the carved circle like she had been given permission. "This place is louder than most because it burned. It soaked. Places keep the songs they were sung in. There’s still a hum in the stone. The metal hears it first."
She moved to stand close enough that her shoulder almost brushed his. No flirt now. Only purpose.
"You dashed in the arena" she said. "Not luck. Not a trick. You braided Eon into those blades for long enough to tear open something in front of you and then you fell through the opening. You called it door. You felt right."
He didn’t answer. The memory hit fast and sideways - a lamp on a table, wind shoved through a window that refused to close, his mother’s voice a word and a warning in one, his father’s hands on a latch that wouldn’t matter, the shape in the doorway, the distance he couldn’t cross. The scene that sits between blinks. The dash that would have cut it in half.
If I’d had this then. If I’d known.
The regret came like a blade. Behind it, the one thing he’d kept from turning into a wound: the vow he’d made with no witnesses. I protect. I close distance. I get there.
Kori watched it in his face and didn’t make a mercy out of words.
"Most people push Eon into muscle and call it training" she said. "They make themselves fast, strong, hard to break. It works. It’s honest. Fewer people learn to send it through a weapon clean enough to get special work back - a dash, a cut that’s more idea than metal, a step that ignores a floor. Even fewer have a Chasmis - the eye that opens and makes a path that only they can walk. Like mine. It gives you a special ability."
She twitched a knife. The air around the blade shelled to a haze and the night went a fraction colder. "Mine is ice" she said, simple, unsmiling. "I can make weather argue with itself. I don’t because I like buildings and flowers. The point is - Chasmis pours in more. It unlocks more routes. But it doesn’t invent desire. You already have enough for trouble."
He nodded once.
"Hikari with her staff will be able to knit it outward and call shapes out of air. Keahi can braid heat into sense if she stops being polite about it. Arashi will turn logistics into a blade because he’s stubborn about elegance. Esen will make noise into pattern. Lynea will measure it and shape it until it shows her respect. Feris... She’ll buy drinks and pretend it was fate. But Ichiro..."
She let the name sit.
"Earth?" Raizen asked.
"Something like it" she said. "No Chasmis. No eye. The ground liked him anyway. Either he cheated reality, or something even weirder is happening. I’ll shake the truth out later."
She took one step in front of him, close enough now that his blades framed her ribs. "Two rules" she said. "Don’t lie to Eon. Don’t cheapen it."
"What does that even mean?"
"It means don’t try to order it around like a boss who’s never lifted anything heavy" she said. "Ask true. Pay in something that isn’t theatrics. If you come horned with anger, it will absorb it and slap you back meaner. If you come with fear, it will echo."
She let the knives’ tips kiss the stone and the thin static flared back into being along their edges.
"And this part is not a joke" she said. "I decided to teach you because you don’t twist power to make yourself taller. You don’t use people to find out how heavy you are. If you were the kind who asks "what can I get away with?" I’d put your head through a wall before I put Eon in your hands."
He met her eyes. She didn’t look away. The ruin didn’t either. The vow he’d made by himself got louder, like someone else had agreed to hear it.
"How?" he asked.
"Stand" she said. "Like that instructor had you stand - joints stacked, breath in your back, not your throat. Don’t grab the blades like they owe you money. Let the weight sit where it wants. We’ll borrow some words - grain, resonance, bleed. Eon has grain. Your body has grain. Luminite has grain. Put them parallel. Ask the metal to remember it’s a choir. When the song starts, decide where the notes die, and chords start. Don’t let it choose."
He exhaled. Knees soft. Feet found the groove without trying. His blades half pulled from the sheathes crossed at the back of his waist - the habit that had always lived in his hands.
"Not both" she said quietly. "Choose one. The other watches."
He slid the right twin a fraction forward and let the left go still, on standby.
"Now" she said. "Think of the dash. Not the spectacle - the line. Not the speed - the door. Not the crowd - the reason."
He saw the space he’d cut in the arena like a seam. He felt the way the world had tilted and let him fall forward instead of down. He didn’t reach for it. He pointed at it with a thought and waited for it to notice.
"Breath low" Kori said, barely sound. "Don’t pull. Invite. If you feel it start to talk back, don’t get greedy."
He waited. Nothing.
"Stop trying" she said. "That was a trick, by the way, but it works. Put the thought down. Pick up your intention, your vow."
He did. Not the words. The shape of it. The ground under it. I arrive. I hold. I take the hit, not the people behind me.
Something at the base of his fingers changed temperature - not hot, not cold, not weather. A sensation like a word being pronounced correctly at last. The twins’ balance shifted without moving. The left blade grew one shade of heavy that was actually right. He didn’t breathe for a second because breathing would be clumsy and he refused to be clumsy now.
"Good" Kori said. She hadn’t looked at the blade. She was watching his face.
"Now - resonance. Listen to what the metal already is. Don’t tell it what it isn’t. Let the ruin hum to it."
He let the bottom of his palms soften until he could feel micro-tremors that were probably imagination and then weren’t.
"Now bleed" Kori said. "Choose where the noise dies. Tip. Hilt. Elbow. Not your chest. Not tonight. Not in the mood to do mouth to mouth breath because you tried too much..."
Then she added: "Again..."
He pictured the path from the hilt to the first quarter of the blade and the way a note might travel a string and find a finger and stop. He pictured it exactly. He told it to stop there. He meant it.
A line of light like the thinnest solder ran along the fuller of the left blade in one clean flicker - not a flare, not a beam, not theater. Static snapped his knuckles as if someone had flicked them with a nail. Dust a hand’s breadth from the edge lifted and sat like a row of thoughtful insects. The brightness was nothing grand. It was enough to prove the room wasn’t lying.
"Stop" Kori said, sharp.
He did. The small flash went out like someone had pinched a wick. The air tried to keep holding shape and then realized it was tired and laid back down. The right twin’s weight emptied and remembered all at once that it was just good steel.
Kori watched the last static die along the edge. She nodded once, like she’d seen a polite bow delivered correctly.
"How do you feel?" she asked.
"Like I almost dropped a plate I wasn’t supposed to be holding" he said.
"Correct" she said. "You get to put it down when I say. You don’t pick it up alone until I tell you that you get to be an idiot unsupervised. Agreed?"
"Agreed."
"Good" she said. "Now your homework is to be boring about it. Eat. Sleep. Stretch. Be kind to your hands and your neck. Do not try to be a comet with a kitchen knife."
He let out a breath that wanted to be a laugh and wasn’t. The adrenaline of almost had only just realized it wasn’t invited to stay. The ruin’s cold came back into his shirt. The thrum in the twins faded to the thing it had been when he had woken: possible.
Kori was lost in thought. Most struggle months to get to the point where Raizen just arrived to. She lifted her knives and their white edges didn’t bother anyone this time. Then, looking around at the equations, words and symbols: "This blew up" she said, very quiet. "People smarter than both of us together put words on stone and made maps with circles and then asked for more than they knew how to carry. Eon doesn’t forgive."
He looked at the black lip of slag around the old pit, the greened glass where heat had won an argument with sand.
"What happened here...?" he asked.
"They tried to keep a storm in a jar" she said. "And then somebody got proud."
He let that settle.
"You’ll learn the boring route first" she said. "Then we’ll do the wicked route - the dash again, but without pretending it was a fluke. We’ll put shields around it so it doesn’t eat the things you don’t mean to feed it. Then we can explore something new"
He nodded.
She glanced past him like she’d heard something the world hadn’t decided to make yet. "We’re done."
"That’s it?" he asked, almost grateful.
"You want more?" she said. "Good sign, but bad one coming from you. You don’t get more. Not tonight."
He sheathed both blades. Kori slid her knives away and the ruin seemed to let go of a breath it had been holding.
They stood a minute in the ring without saying anything. Far off, the line to the harbor blinked a single aircraft into being and then put it back where it came from. The pines traded gossip. The dew on the grass in the clearing hadn’t been impressed by any of this, which was its right.
On the walk back her voice returned to Kori again - looser, amused at things that weren’t jokes.
"We’ll start building capacity" she said. "Food, sleep, reading, those maps you love to pretend you don’t love. You can increase how much Eon your body can carry by becoming a better body and a better mind. Simple. Painful. Unimpressive, but hella important. I’ll yell, and you’ll pretend to argue. We’ll both be happy."
"What happens if people get greedy?" he asked.
"They learn what it feels like to be scolded by an old woman with a staff who can end you with posture" she said. "And then I’ll end them more politely."
He made the sound that was almost a laugh again.
After some time and an awkward silence of a few minutes, she added, softer "Hey. That spark? You didn’t make it dangerous."
"I felt it thinking about it" he said.
"Yes" she said. "It’s supposed to. It should scare you just enough to keep your hands honest."
They reached the change where stone learned to be city road again. The gate recognized her the way a loyal dog recognizes the sound of its own name. The slit opened a body-width. The night tasted different on the other side.
Neoshima took them back like a stage takes back actors through a trapdoor. The eight-lane artery held its slow river. A sign blinked and tried to sell them a breakfast the time didn’t agree with. Drones crossed and recrossed in tidy lanes like stars with regulations. Somewhere in a side street, somebody was still playing the violin with more heart than talent and no audience but two cats.
They went home by a quiet route. He didn’t speak. Neither did she. The city didn’t need words either.
At Kori’s door she turned the bolt twice like a heartbeat, the mirror of when she’d let him out. She leaned against the frame and the tease found the corner of her mouth again, like a cat that will always come back.
"Don’t sneak" she said.
"I won’t" he lied, and meant it.
"Liar" she said kindly. "Sleep. Tomorrow, we pretend school matters. Then we make it matter."
He started up the stairs and she added, like an afterthought that had been waiting for the right time, "You did well. Not because you made a spark. I mean that’s the main thing, but especially because you stopped when you needed to."
He looked back. She had already looked away, the way she did when anything like praise tried to show its face.
Up in the attic he set the twins under the pillow as if they’d sleep too. Hikari breathed even, the kind of sleep you get when a midnight doesn’t come for you. Raizen smiled, then turned, laying. Before he could do anything, a hand gripped his shirt. It was Hikari’s. She was still asleep, but muttered "Please... Mother... Don’t leave me here..."
He gently took her hand, set it next to her, and whispered, as if he never meant it to be for someone else "I’ll never leave. I promise."
The window put a stripe of city pulse across the quilt. He finally rested on his back and watched it climb the wall.
Down the street, something beeped like a truck dreaming. Far off, the sea counted in its old, slow way. In his palm, where the blade had woken, a ghost-sensation lingered - not heat, not cold, not anything like weather, just the memory of a word he’d learned to say correctly once and wasn’t going to forget. In the morning, there’d be class. There’d be training. There’d be a city that performed and a ruin that refused to. Somewhere between them lived the thing he was learning to hold without breaking.
Tonight, a spark was enough.
But before he slept, guess what? Two hundred sit-ups!
