Enna had rearranged the apartment.
The kitchen table was pushed against the far wall. The center of the room was cleared. A plastic tarp covered the floor. On the tarp, arranged in neat rows like specimens in a lab, sat a collection of objects: a tin can, a ceramic mug with a chip in the rim, a brass doorknob, a glass bottle, a section of copper wire, a chunk of concrete from the building's crumbling foundation, and a dead lightbulb.
Cael stood in the doorway and stared.
"You're barred from using your ability," Enna said from her wheelchair, a notebook in her lap, three pens at the ready. "In public. This is not public. This is our apartment. Now get in here and break my mug."
"That's your favorite mug."
"Science requires sacrifice. Also, I hate that mug. It leaks."
Cael stepped onto the tarp. The core hummed behind his sternum, the same low frequency it had carried since the ceremony. Eighty-four percent. The board's censure sat in his pocket like a summons to a funeral. He wasn't supposed to touch the Ruin's power at all.
"We need ground rules," Enna said. "I'll measure your vitals before and after each test. You will not exceed three deconstructions per session. You will stop immediately if your core drops below eighty percent. These are non-negotiable."
"You're fifteen."
"I'm also the only person running a controlled study on your survival mechanics. Age is irrelevant to competence. Pick up the tin can."
He picked up the tin can. Held it in both hands.
"On my mark. Three, two—"
The can dissolved. Cael hadn't waited for the mark. The aluminum separated into a cloud of particles that hung between his palms, silver-gray and weightless. The core cataloged the composition: aluminum alloy, tin coating, trace iron. Simple. Single-material, low complexity. The cost was barely a whisper.
"Point two percent degradation," Enna said, reading the diagnostic pen Rem had left behind. She wrote it down. "Now the ceramic."
The mug cost more. Ceramic was a composite, silica and alumina and feldspar fired together, and the core had to sort each component. The particles that emerged were a mix of colors, glassy whites and dull grays, orbiting his fingers like a tiny solar system of broken dishes. Point-five percent.
The brass doorknob. Point-three. The glass bottle. Point-four. The copper wire. Point-two, nearly free, because his core already knew copper from the construction site.
The concrete chunk. Cael picked it up and felt the core strain. Concrete was ugly stuff, compositionally speaking. Cement paste binding sand and gravel and God knew what else, every batch different, no two chunks identical. The deconstruction was slow, grinding, the particles separating reluctantly like a bad foundation being pried apart piece by piece.
One full percent. The core ached.
Enna recorded everything. Her handwriting got faster and smaller as the data accumulated, three colors of ink building a picture.
"Pattern confirmed," she said. "Simple materials cost less. Known materials cost less. Complex composites cost more. Your core is essentially a translator, breaking down molecular bonds. The more bonds, the more energy it burns." She tapped her pen against the notebook. "Which brings me to the real question."
Cael lowered himself to the floor, legs crossed, the tarp crinkling under him. He knew what she was going to ask. He'd been thinking about it since the first night in the construction yard.
"If you can break materials down into raw components," Enna said, "and your core catalogs those components in precise molecular detail, then you have a blueprint library. You know exactly what things are made of." She leaned forward in the wheelchair. "Can you use those blueprints to put materials back together?"
"I tried that first night. It didn't work."
"Try again. You've cataloged more materials now. Maybe it's cumulative."
Cael gathered the aluminum particles from the tin can. They drifted toward his hands when he concentrated, drawn by whatever force the Ruin used to hold deconstructed matter in suspension. He pushed. Willed the particles to reassemble. Tried to reverse the process, to fuse instead of separate.
Nothing. The particles shivered, tried to align, and fell apart like wet sand.
"Same as before," he said. "I can see the blueprint. I can't build from it."
Enna chewed her pen. "Not yet. The deconstruction came instinctively. Maybe reconstruction needs a trigger. Like the deconstruction did — it first activated under threat."
"You want me to feel threatened by a tin can."
"I want you to consider that your power might unlock in stages. Each stage triggered by necessity." She flipped to a new page. "Now. The important part. Can you use deconstructed materials to repair your own core?"
He'd been avoiding this test. Not because he thought it wouldn't work. Because he thought it might, and that would mean the Ruin had given him a path to sustain himself, and gifts from ancient sealed entities didn't come without fine print.
"Pick a material," Enna said. "Something your core already knows. Minimal deconstruction cost. Feed the raw essence into the core and see if the integrity goes up."
Cael picked up the copper wire. Already cataloged. Cheapest material to break down. He dissolved it and held the copper particles in his palm.
Then he pushed them inward.
Toward the core.
The particles phased through his skin. Not painfully. They just... sank, absorbed through his palm and into his bloodstream and drawn toward the humming center of his chest like iron filings pulled toward a magnet. The core absorbed them. The copper essence dissolved into the artificial structure, filling a hairline fracture that Cael hadn't even known was there.
The diagnostic pen on Enna's lap beeped.
"Point-one percent recovery," she said. Her voice had gone very quiet. "You gained point-one percent from a six-inch piece of copper wire."
Eighty-four point one. A rounding error. A fraction of what he'd spent tonight.
"It's not enough," Cael said.
"It's proof of concept." Enna was writing furiously now, all three pens in rotation. "Copper wire gave you point-one. Low-grade material, low recovery. But what about high-grade? What about refined alloys? Flame-forged metals? Soul-conductive crystals?" She looked up. "If the recovery scales with material quality—"
"Then I need better materials."
"And better materials cost money."
They looked at each other across the tarp, across the scattered particles of aluminum and ceramic and glass, in an apartment they could barely afford in a district that nobody cared about.
"How much do Flame-forged materials cost?" Cael asked, already knowing the answer.
"A Flame-forged steel ingot runs about two hundred crowns at market rate. A soul-conductive crystal shard is five hundred. Zenith-grade material, the stuff the Academy uses for equipment, starts at a thousand crowns per unit."
His monthly income from the construction site was eighty-four crowns after the pay docking. His parents' hospital bill was four hundred and seventy-five. Their rent was sixty. Food was whatever was left, which was usually nothing.
"Burn it," he said.
"There are other sources." Enna tapped the page she'd been writing on. "Salvage. Abandoned Flame zones outside the city. Places where old battles left residue. Monsters that accumulate Flame-infused materials in their bodies. The Char District scrap yards sometimes get Flame-contaminated metal from military surplus." She paused. "It's dangerous. It's illegal. And it's the only option you can afford."
"You've already made a list."
"I've made three lists. Ranked by risk-to-reward ratio." She tore a page from the notebook and handed it across. Her handwriting, cramped and precise, filled both sides. Locations. Estimated material grades. Known hazards. She'd been planning this since she saw the bruises.
"Enna."
"Don't. Don't tell me it's too dangerous or that I should focus on school or that you'll handle it. I can't walk, Cael. I can't fight. I can't go to these places and get the materials myself. But I can do this." She held up the notebook. Pages of calculations. Hours of research. "This is what I can carry. Let me carry it."
He took the list. Folded it. Put it in his jacket pocket next to the disciplinary censure and the Crucible Trial notification and all the other pieces of paper that were trying to decide his future.
"Thank you," he said. Enna's eyes went bright for a second. She blinked it away and shoved her glasses up her nose.
"Clean up the tarp. You got ceramic dust on my research."
---
The Greenwell scrap yard was three blocks deeper into the Char District than anyone with sense would go after dark.
Rem was already there when Cael arrived. He was sitting on an overturned bathtub, eating a sandwich that looked like it had been assembled by someone with no concept of structural integrity. Lettuce hung from one end. Something brown oozed from the other.
"You're late," Rem said, mouth full. "Also I brought food. Also this sandwich is terrible. Also your face looks worse than yesterday, right? The bruises. They're spreading."
"Surface damage. Ribs are healed."
"I know they're healed, I healed them. But bruises are soft-tissue, and my healing focuses on structural damage, not cosmetic, which means — anyway, here." He held out a second sandwich, equally destroyed. "Eat."
Cael ate. The sandwich was terrible. Rem watched him eat with the satisfied expression of someone whose love language was badly constructed food.
They worked through the scrap yard for two hours. Cael deconstructed whatever he could find that was worth cataloging: rusted iron, tarnished brass, cracked ceramic pipes, a chunk of something that might have been a Flame-powered engine casing but was too corroded to tell. Each deconstruction cost less than the last as his core's material library grew. Efficiency through repetition.
Rem's phone buzzed at 9:14. And 9:22. And 9:31.
Each time, Rem glanced at the screen, and each time, his face did a specific thing: a tightening around the mouth, a quick look away, a shift in posture that was trying very hard to look casual and failing. He silenced the phone after the third call.
"Clinic?" Cael asked, not looking up from a corroded valve he was dissolving.
"Yeah. Scheduling thing. It's fine." The words came out too fast, clipped at the edges, nothing like Rem's usual rambling cadence. When Rem spoke in short sentences, something was wrong. Cael had known him long enough to read the architecture of his moods, and this one had a crack in the foundation.
He didn't push. Rem would tell him when Rem was ready, or Rem wouldn't, and pushing would only make the crack worse.
"Hand me that pipe section," Cael said instead.
Rem handed it over. Their fingers brushed. Rem's healing Flame sparked involuntarily, the faintest green glow, and a tiny cut on Cael's index finger that he'd gotten from a sharp edge sealed itself.
Cael started laughing.
Not a chuckle. Not a smile. Full, helpless, doubled-over laughter that shook his shoulders and made his healed ribs ache. The sound came out of him like water from a broken pipe, uncontrolled and unstoppable, and he sat down on the ground in the middle of the scrap yard and laughed until his eyes streamed.
Rem stared at him. "Oh no. Oh no no no. That's the laughing one. I'm sorry, I didn't mean to — my healing just does that sometimes, yeah? The side effects are random, I can't control which one—"
Cael waved a hand, still laughing. He couldn't stop. The sound filled the scrap yard, bouncing off rusted metal and cracked concrete, and it was absurd and embarrassing and the first genuine laughter he'd produced in longer than he could remember.
It took three minutes to subside. When it did, Cael was sitting on the ground with tears on his face and Rem was crouched next to him, looking mortified.
"Sorry," Rem said. "I know it's annoying. The side effects. People at the clinic hate them. One guy, I healed his broken arm and he spent twenty minutes convinced he was in love with the nurse. She was sixty-four. It's — my healing is broken. I know it's broken."
Cael wiped his eyes. His stomach hurt from laughing. His face ached from smiling. The scrap yard was dark and cold and smelled like rust.
"Rem."
"Yeah?"
"Your healing just made me happy for the first time in two years." He looked at Rem, at the round worried face and the kind eyes and the calloused hands that healed people wrong but healed them anyway. "Don't apologize for that."
Rem's lip trembled. He sat down on the dirt next to Cael. He didn't say anything for a while, which was Rem's way of being so full of feeling that even his mouth, usually running three conversations ahead of his brain, couldn't find the words.
His phone buzzed again. He turned it off.
They sat in the scrap yard, shoulder to shoulder, surrounded by the deconstructed remains of things nobody wanted anymore. The silence between them was load-bearing. It held up everything that words would've made smaller.
After a while, Rem sniffed. Rubbed his nose on his sleeve. "So. The Crucible."
Cael blinked. "What?"
"You got the notification, right? Crucible Trial eligibility. I got one too. All newly ignited Flame users are eligible. Even—" He paused.
"Even Cinder Smiths."
"I was going to say even people with terrible fashion sense, but yeah, that too." Rem bumped his shoulder against Cael's. "I'm going. I registered this morning."
"Rem, you're a Healer. The Crucible is a combat trial."
"Yeah, and teams need healers, right? Five-person teams, at least one support class required by regulation. I'm support." He grinned. The grin was lopsided, slightly forced, and underneath it was something Cael recognized because he wore the same expression every time he walked into the hospital: desperation wearing the mask of confidence. "Besides. The Crucible prize pool includes materials. Flame-forged materials. The winners get access to the Zenith Academy resource vault."
Cael went still.
"I looked it up," Rem said. "First-place team gets guaranteed academy admission plus a materials stipend worth twenty thousand crowns. That's two years of hospital bills. That's core repair materials. That's—"
"Everything."
"Everything. Yeah."
Cael stared at the dark sky above the scrap yard. Somewhere past the Char District's coal-smoke haze, the stars were probably out. He'd stopped looking for them.
"I'm censured. Barred from using my ability."
"The censure applies to public use. The Crucible is a sanctioned competition. Different jurisdiction. I checked." Rem pulled a folded printout from his pocket. "Section twelve, paragraph four: 'Participants in sanctioned Flame trials operate under trial authority, not municipal authority. All registered abilities are permitted within trial bounds.' Your censure doesn't apply inside the Crucible."
Cael took the printout. Read it. Read it again. The legalese was dense, but the meaning was clear: whatever rules the disciplinary board had put on him evaporated the second he stepped into the Shattered Reach.
"You found a loophole."
"I found several. That's just the best one." Rem stood up, brushed dirt off his pants, and offered Cael a hand. "So. Are we doing this?"
Cael took his hand. Stood.
The core hummed. Eighty-three point four percent, after tonight's practice. Dropping. Always dropping. He needed materials. He needed money. He needed a way forward that didn't dead-end in a construction yard and a hospital bill and a slow decline toward zero.
The Crucible was dangerous. Teams died in the Shattered Reach every year. The competition was designed for B-ranks and above, and he was an F-rank Cinder Smith with a power that ate him alive from the inside.
"We need three more people," Cael said.
"I know."
"Nobody's going to team with a Cinderborn."
"I know that too." Rem grinned again. This time it reached his eyes. "But we've got six days. And you can dissolve steel with your hands. I bet we can find three idiots brave enough to think that's cool."
Cael almost smiled. Almost. The muscles moved. The structure held.
They walked out of the scrap yard together, into the dark streets of the Char District, where the lamps ran on coal and the buildings leaned and nobody looked up.
Rem's phone, turned off, sat silent in his pocket. Whatever was calling him could wait one more night.
Cael's phone, still showing the Crucible notification, sat in his. Six days. Three team members. A combat trial designed to break people with real Flames.
He flexed his hand. The copper dust from the wire still glittered faintly under his nails.
