The training lawn was loud in the harmless way only first-years could manage.
Wooden constructs rose from the ground in shifting formations, rotating targets, sliding walls, and hinged panels that snapped open and shut like jaws.
Chalk sigils flared and faded along the grass as instructors' wards kept stray spells from turning into accidents.
Aether shimmered in pale layers above the field, lines drawn and redrawn as casting circles bloomed, faltered, corrected.
It was the sort of noise that meant the world was still normal.
Estelle stood at the center of a formation circle, her sleeves rolled just slightly too high, constellation-flecked eyes bright with focus. A faint pattern of starlight pulsed behind her pupils, as if the sky had decided to take up residence in her gaze.
"Sagittarius," she said softly.
A bow of starlight formed in her hand, neither wood nor pure light, but something in between. Threads of distant pattern braided into a curved arc, the string humming with quiet tension.
She drew back.
The arrow was not a simple bolt of Aether.
It was a line traced between stars.
When she released, it didn't fly straight.
It curved, graceful, elegant, almost unreasonable in how prettily it moved.
The arrow struck three rotating targets in succession, rebounding in a clean arc before dissolving into glittering fragments that fell like harmless snow.
A few students clapped.
Klaris stood off to the side, arms folded, posture neat and watchful. She nodded once, approving, like someone who had learned to give praise with restraint.
"Your control's improved," Klaris said.
Estelle smiled, pleased but not smug. "I tightened the weave between nodes. It's smoother now."
"It is," Klaris agreed. "Though the curvature—"
"—wasted seventeen percent of your output shaping it."
The voice wasn't loud.
It wasn't sharp, either.
It simply arrived, and the sound of the lawn thinned around it as if people's attention had been pulled into a single, narrow point.
Estelle turned.
He stood near the edge of the circle, hands clasped behind his back as though he were observing a lecture rather than interrupting a drill.
Tall for a first-year. Uniform immaculate. Black hair falling precisely where it should, as if it had been arranged and then ordered never to move again.
His eyes were the strangest part.
Not because they were black.
Because they reflected nothing but the light around them, no warmth, no spark, no visible hunger.
No challenge.
No admiration.
Only assessment.
Estelle blinked once. "Seventeen?"
He nodded, expression unchanged. "Your Sagittarius vector curved for aesthetic symmetry. You widened the arc beyond functional necessity. Shorten it by two degrees. Reduce the second rebound. Drag decreases. Stability increases."
A pause.
"Impact remains identical."
A few students shifted uncomfortably, as if they'd been told a joke with no punchline.
Klaris's gaze narrowed. "You calculated that just now?"
"Yes."
There was no pride in his tone, no hint of smugness. It was simply a matter-of-fact statement, as straightforward as if he were reporting the weather.
A voice from behind Klaris piped up, half-indignant, half-amused.
"Seventeen percent?" Cesare echoed, stepping around a moving wall that politely tried to cut him off. He had flour on his sleeve, again, and a smear of something sweet near his jaw that suggested he'd been practicing his magic the way he always did: by snacking mid-cast and pretending it didn't count as a distraction.
He squinted at the boy. "That's so specific it's basically personal."
The black-eyed boy looked at him. "Specificity reduces error."
Cesare spread his hands as if presenting a counterargument to the heavens. "And joy reduces misery. That's my academic position."
Estelle's mouth twitched.
Klaris glanced at Cesare like she was deciding whether to scold him or adopt him as comedic relief. "He's not wrong," she said, which was about as close to laughter as Klaris tended to get.
Hikaru, who had been arguing with another student about compression ratios in the adjacent circle, turned, interest sharpening his face. "You said drag decreases. You're using structural modeling?"
The black-eyed boy nodded once. "Yes."
Hikaru's brow lifted. "Primary discipline?"
"Yes."
That answer should have been funny. Somehow it wasn't.
Hikaru nodded slowly anyway, as if he'd been given something solid. "Makes sense."
Estelle crossed her arms. "Magic isn't just numbers."
"Magic is only numbers," the boy replied evenly. "People add story."
Cesare made an offended sound. "Excuse you, story is literally what makes anything worth doing."
The boy looked at him again, calm as stone. "Worth is subjective."
Cesare stared for a second, then leaned toward Estelle like he was about to whisper a secret. "Is he… always like this?"
"I don't know," Estelle whispered back. "I just met him."
"I don't even know your name," Estelle said, louder now.
He inclined his head slightly, the motion so controlled it looked rehearsed.
"Isembard Vaelor."
The name landed without flourish.
Around the circle, a few students blinked in recognition.
"Oh," someone whispered. "He's the one who scored full marks on theoretical modeling."
Another murmured, "He doesn't waste Aether. Like… at all."
Cesare made a face. "That sounds exhausting."
Isembard didn't react to that either, which somehow made Cesare's expression soften into something almost impressed.
Estelle stepped closer, curiosity threading through her irritation. "So what would you have done?"
Isembard didn't hesitate.
He stepped into the circle as he belonged there, like the circle had been drawn for him.
He lifted one hand and traced a narrow line in the air.
No constellation flare. No dramatic bloom.
Just a line.
Compressed.
Dense.
Precise.
A bow formed in his grip, smaller than Estelle's, sharper, stripped of any curve that wasn't required. The string hummed like a taut wire.
When he drew back, the arrow was barely visible, a thin filament of condensed Aether.
He released.
It didn't curve.
It corrected.
Mid-flight, it adjusted its trajectory at mathematically clean intervals, striking the same three targets in a faster sequence before burying itself in the fourth construct with a neat puncture that didn't splinter wood so much as inform it that it had been defeated.
The fourth construct toppled with a wooden groan.
The lawn fell quiet.
Estelle stared at the targets.
Then at him.
"That wasn't beautiful," she said.
"It worked," Isembard replied.
Cesare lifted a hand. "Okay, but if beauty is 'waste,' why do we have capes?"
Several students glanced down at their uniform cloaks as they'd just realized a terrible truth.
Hikaru snorted quietly, but it was the first sign he'd made all day that he could be amused without immediately analyzing the humor.
Klaris ignored the cape question and focused on the spell. "You compressed the strand so tightly it barely bled. That output control—"
"Is efficient," Isembard finished.
Estelle held his gaze. "Did you feel anything?"
Isembard blinked once.
"Yes."
A beat.
"It was sufficient."
That answer, more than any insult, unsettled her. Not because it was cold, but because it sounded honest.
Estelle's constellations pulsed faintly, as if responding to her mood. "Creativity isn't waste."
"Unnecessary curvature is," he corrected calmly.
Cesare stepped between them, not physically blocking, but inserting himself the way only Cesare could, as a pastry shoved into an argument.
"Curvature can be necessary," Cesare announced. "For example: croissants. Try making a straight croissant. You can't. It's wrong on a spiritual level."
Isembard's gaze flicked to him. "Food is not relevant."
Cesare gasped as if struck. "Food is always relevant."
Hiyori, who had been drilling light bursts at the far edge of the lawn, precise and sharp, paused long enough to glance over. Her eyes moved between Estelle and Isembard, then slid away again as if she'd decided the tension wasn't her problem.
But she didn't go back to casting right away.
She watched quietly.
The instructor overseeing their cluster, a second-year assistant with ink-stained gloves, cleared her throat. "All right," she called. "Enough. You're here to practice, not to build duels with your mouths. Reset the circles. We're switching to adaptive patterns."
Groans rippled through the first-years. Adaptive patterns meant the constructs would change while you cast.
Which meant your clever plan would collapse mid-spell if you weren't careful.
"Positions!" the assistant barked. "Pairs and trios. Choose fast."
Klaris immediately moved as if the universe had assigned her the role of leadership. "Estelle, you take mid-range. Hikaru, support anchor. Cesare—"
Cesare raised both hands. "I'm not support. I am vital morale."
"You're support," Klaris said flatly.
Cesare's shoulders sagged in theatrical despair. "Cruel."
Hikaru's eyes flicked to Isembard. "You joining?"
Isembard paused, as if the idea of joining a group required recalculation.
"Yes," he said.
No warmth in it. No reluctance either.
Just a fact.
They arranged themselves in a loose arc, facing the constructs as the ground sigils flared anew. Targets rose, shifted, rotated, then stopped.
For half a heartbeat, everything held still.
Then the constructs began to move.
Fast.
Panels snapped open. Walls slid. Targets rotated unpredictably, as if the lawn itself had decided to be difficult out of principle.
"Go!" the assistant shouted.
Estelle drew her bow again, constellations shifting, Leo, a flare of confidence behind her eyes. She loosed a star-line that struck a moving target cleanly.
Klaris cast thin Aether ribbons that steadied their circle, preventing the shifting walls from clipping them as they advanced.
Hikaru lifted his hand, and a quiet field settled around them, subtle, supportive, ready to cancel stray discharges if someone's spell misfired.
And Cesare—
Cesare slapped his palms together and pulled Aether like dough.
A stack of airy bread loaves appeared midair, impossibly tall and wobbling, like someone had built a tower out of baked defiance. It drifted forward and thunked into a sliding wall, blocking it long enough for Klaris to step around.
"Cesare!" Klaris snapped.
"What?" Cesare yelped. "It works!"
"It's ridiculous."
"It's effective!"
Isembard moved without comment.
He didn't raise a flashy circle.
He didn't shape an aesthetic spell.
He traced thin lines, straight, dense, rapid, each one aimed at the exact moment a target's rotation exposed its weakest angle.
Three targets dropped in sequence.
Two more.
No wasted movement.
No wasted breath.
It was… unsettling to watch.
Not because it was powerful.
Because it was empty.
Estelle noticed it mid-cast, felt annoyance flash through her chest, and almost missed the way the constructs changed.
A wall snapped open behind them.
A target rose in the wrong place, too close, too fast.
The assistant's voice carried sharply: "Adaptive shift! Don't freeze!"
Estelle pivoted, but her arrow line was already committed. It curved wide, beautiful, and would miss.
She clicked her tongue and tried to tighten the arc—
And then Isembard moved.
Not to correct her spell.
To correct the field.
He stepped into the path of her arrow with a hand lifted, fingers splayed.
Hikaru's field flared instinctively, ready to cancel—
But Isembard didn't cancel.
He bent.
Not the Aether itself.
The conditions.
He shot a thin line of condensed Aether into the ground, a precise anchor, and the air around Estelle's arrow shifted, subtle pressure, a tiny correction in trajectory.
The arrow's curve tightened mid-flight.
It struck.
The target shattered.
Estelle blinked, breath catching.
"That—" she started.
"I adjusted the vector," Isembard said, as if that explained everything.
Cesare stared at him as he'd just seen someone rewrite bread physics. "Did you just—"
"Yes," Isembard said again.
Klaris's eyes narrowed, not suspicious, interested. "You didn't rewrite her spell," she said. "You rewrote the environment."
"Less invasive," Isembard replied.
Hiyori's light burst detonated across three targets, clean and sharp, and she didn't look impressed.
But she did glance at Isembard again.
Then the lawn shifted hard.
A wall dropped between them and the final set of targets. The ground sigils flared with Aetheric feedback, small distortions that made casting circles wobble as if the chalk itself was trying to crawl away.
A few students in the adjacent group stumbled as their spells fizzled.
"Feedback sigils!" the assistant shouted. "Don't brute force, adapt!"
Estelle's constellations flickered, momentarily unstable.
Klaris bit her lip, calculating.
Hikaru's field tightened, trying to stabilize their casting—
And Cesare, of all people, stepped forward.
He breathed in, pulled Aether through his hands—
And made sugar.
Not metaphorical sugar.
Not "sweetness" symbolism.
Actual crystalline Aether that fell like glittering sand.
It scattered across the feedback sigils, clinging to the distortions and highlighting them.
The distortions became visible, like ripples made of glass.
Klaris's eyes widened. "Cesare—"
"I can't fix what I can't see!" Cesare shouted back. "So I made it visible!"
Estelle stared. That's… actually smart.
Hikaru snapped his hand outward, canceling only the worst distortions now that they were visible, and the circle steadied.
Klaris immediately cast a stabilizing ribbon along the ground, stepping precisely between the feedback ripples.
They moved.
Together.
For once, their spells didn't clash, they layered.
They reached the wall.
Isembard lifted his hand, ready to puncture the final target through the barrier with a clean, straight thread—
And then the target moved.
Not rotated.
Moved.
It slid sideways, behind the wall, in a position that made a straight line impossible unless he broke the wall.
Breaking the wall would trigger the wards.
Triggering the wards would count as a failure in control.
Isembard's hand froze in the air.
Only for a fraction of a second.
But Estelle saw it.
That tiny pause.
The moment when his perfect solution failed to exist.
"Two degrees," Estelle said quickly, almost grinning despite herself. "Try curving it."
Isembard's eyes flicked to her.
His jaw tightened a hair.
He didn't answer.
But his hand lowered.
And when he cast, he did something he hadn't done before.
He allowed the thread to bend.
Not dramatically.
Not beautifully.
Just enough.
A controlled curve, functional, minimal, but undeniably curved.
The thread slid around the wall's edge and struck the final target.
The target fell.
The assistant's whistle pierced the air. "Good! Reset!"
A handful of students cheered in relief.
Klaris exhaled like she'd been holding her breath for a minute. "That was messy."
Cesare wiped sweat from his brow and immediately got flour on his face again. "Messy is how you know it's real."
Estelle looked at Isembard.
His expression hadn't changed.
But his eyes—
For the briefest instant, something lit behind the black.
Not warmth.
Not joy.
A flare.
Like a spark catching in dry wood.
It was gone as quickly as it came, swallowed under the smooth blankness again.
Isembard blinked once.
Then his mouth moved, almost like he was irritated with himself for having a mouth at all.
"…That was inefficient," he said.
Estelle's smile sharpened. "It worked."
"It required deviation."
"Welcome to reality."
Isembard stared at the fallen target as if it had betrayed him.
Cesare leaned in toward Estelle, whispering loudly enough for everyone to hear. "Did you just make the hollow boy curve his spell? That's basically emotional growth."
Isembard turned his head slowly.
Cesare held up both hands immediately. "Compliment. That was a compliment."
Hikaru's mouth twitched again. "He's not hollow," Hikaru said, thoughtfully. "He's… choosing it."
Estelle tilted her head. "Why would anyone like being hollow?"
No one answered right away.
Not because they didn't have guesses.
Because the question felt too personal.
Isembard looked at Estelle.
For a moment, it seemed like he might say something honest.
Then he shrugged, small, controlled.
"Emotion adds unpredictability," he said. "Unpredictability adds risk."
"And risk adds life," Cesare shot back.
Isembard's gaze returned to the lawn, to the shifting constructs, to the clean logic of targets and angles.
"Life," he said evenly, "is optional."
Estelle's constellations dimmed a fraction, as if the stars themselves didn't like that sentence.
Klaris folded her arms again, chin lifting. I'm not letting someone like him decide what's optional.
Hiyori finally spoke, voice quiet but clear. "You're wrong."
Isembard turned to her.
Hiyori didn't flinch. "You can't remove the part of yourself that reacts and still call what's left 'you.'"
Isembard stared for a long moment.
Then he nodded once.
Not agreement.
Acknowledgment.
"Noted," he said.
Which somehow made it worse.
The assistant shouted for them to regroup, and the training lawn swallowed their tension back into motion.
Estelle reset her circle, jaw set, eyes bright.
Klaris adjusted her stance, counting angles.
Hikaru resumed his analysis under his breath.
Cesare conjured a tiny loaf in his palm and took a bite as he'd earned it.
And Isembard—
Isembard watched the constructs.
Watched the spells.
Watched the way people wasted power on flourish, and the way flourish sometimes made them better instead of worse.
It bothered him.
Not because it disproved his logic.
Because it tempted him.
Later, when the drills finally ended and the first-years spilled toward the corridors in sweaty, laughing clusters, Estelle lingered behind.
She pretended to adjust her sleeve.
Pretended to redraw her constellation lines.
But her eyes kept flicking toward the boy at the edge of the lawn.
Isembard Vaelor stood alone, hands behind his back again, staring at the flattened grass where his curved thread had struck.
Estelle approached slowly.
"Hey," she said.
Isembard didn't turn immediately, like he'd measured whether responding was worth the effort.
Then he faced her.
"Yes."
Estelle crossed her arms. "So," she said, trying not to sound like she was issuing a challenge even though she absolutely was, "creativity is still unnecessary?"
Isembard held her gaze.
A beat passed.
Then he spoke, calm as ever.
"Creativity is another piece," he said. "If it produces results, it can be used."
Estelle smiled, small, bright, stubborn. "Then you'll have to get used to using it."
Isembard blinked once.
For the first time, his eyes flickered again, faint, brief, almost angry.
Not at her.
At himself.
"Perhaps," he said.
Then he turned and walked away, posture perfect, steps quiet, expression blank.
But as he left the training lawn, one thought pressed against the smooth emptiness he liked to keep inside himself.
A curve had been necessary.
He had enjoyed it.
And that realization, sharp, unwanted, alive, almost made him furious.
Because it meant the hollow wasn't as complete as he'd wanted.
And somewhere behind him, Estelle Rowan redrew her Sagittarius line again.
This time tighter.
This time sharper.
Still beautiful.
Still hers.
