Dusk settled over the Crownoval estate like a quiet veil, turning the sky a deep indigo. Lanterns along the outer paths flickered to life, casting long shadows across the eastern training grounds. This section was quieter than the main field, reserved for advanced drills and personal practice. Klein arrived exactly as the last light faded, his steps measured and unhurried.
Lirael Voss was already there, practicing forms alone under the open sky. Her training sword moved in precise arcs, each swing carrying a faint blue shimmer of mana along the blade edge. She flowed from stance to stance without pause, her breathing steady, her auburn braid swaying with the motion. The girl moved like someone who had learned swordplay not in comfortable halls but on contested borders where hesitation meant death.
She noticed him immediately and lowered her blade, wiping sweat from her brow with the back of her hand.
"Second Young Master," she said, a hint of challenge in her tone. "You actually came. Most nobles with new tricks prefer audiences and safety. Not empty grounds after dark."
Klein stopped a respectful distance away, noting the way her mana signature pulsed in rhythm with her heartbeat - sharper now than during the morning assessment, honed by real exertion.
"Observation under controlled conditions is useful," he replied calmly. "Live pressure provides better data. You offered a real spar. I accepted."
Lirael's green eyes sharpened with approval. She tossed him a spare training sword from a nearby rack. The hilt felt solid and worn, balanced for quick work.
"No shields this time. No fancy loops unless you earn them. We spar light - first to three clean touches wins. But you explain every mana trick you use while we fight. Deal?"
Klein caught the sword and tested its weight. He had never trained with one in this life, yet the motion felt natural enough through muscle memory. He formed a thin resonant layer around his free hand and forearm - not a full shield, but a flexible harmonic buffer tuned to absorb impact.
"Deal," he said.
They circled each other slowly. Lirael attacked first - a quick testing cut aimed at his shoulder. Klein stepped inside the arc, letting the blade glance off his resonant forearm. The contact hummed softly, the frequencies aligning for a split second before the force redirected outward.
"First observation," Klein said evenly as he countered with a simple thrust. "Your pulse is timed to muscle contraction. It peaks at the moment of impact. Mine stays constant until adjusted."
Lirael parried smoothly, her sword ringing against his. She pressed forward with a series of short, economical strikes.
"Border training," she replied between breaths. "You waste mana if you keep it flowing all the time. Pulse it when the blade needs it. Saves reserves when you're outnumbered on the frontier."
Klein noted the data. Her method was efficient for prolonged combat. He adjusted his own flow mid-exchange, syncing a small loop to match the rhythm of her swings. The next parry felt smoother - less jarring, more like guiding a current around an obstacle.
"Second observation," he continued. "Matching frequency mid-motion reduces resistance. Your blade's natural harmonic is slightly higher than mine. Adjusting for it turns defense into redirection."
Lirael's eyes lit up with genuine interest. She increased the pace, her strikes coming faster now, each one carrying a sharper mana pulse.
"You talk like a smith tuning a sword instead of swinging one," she said with a short laugh. "But it works. I felt that last parry take half the force out of my swing. Most mages I've fought just dump power and hope it lands."
They traded blows for several minutes. Klein's movements remained economical - no wasted steps, no dramatic flourishes. He treated the sword as an extension of his mana circuit rather than a weapon of brute strength. Each block or counter was calculated: visualize the blade's frequency, align the loop, guide the energy.
Lirael landed the first clean touch - a light tap to his side when he over-adjusted his resonance.
"One for me," she called. "You think too much before moving."
Klein acknowledged it with a nod and immediately refined the timing. On the next exchange he anticipated her pulse, layering a brief emotional catalyst - focused curiosity - into his flow. His counter came sharper, the sword edge glowing faintly as the mana density increased.
He scored the second touch on her forearm guard.
"Equal," he said. "Emotional resonance adds amplitude without extra draw from the core. Useful under pressure."
Lirael stepped back for a breath, lowering her sword slightly. Sweat glistened on her brow, but her stance stayed ready.
"Border skirmishes taught me something similar," she admitted. "When raiders hit at night and fear tries to freeze you, you lean into the feeling instead of fighting it. Turns the shake in your hands into sharper swings. Never heard anyone call it 'emotional resonance' though. Sounds like something out of old academy scrolls."
Klein reset his guard.
"It is measurable. Heightened states alter flow density. The books describe it vaguely as 'willpower.' In reality it is a catalyst variable - consistent across users if properly guided."
They resumed. The third round went longer. Lirael's attacks grew more creative, mixing feints with sudden pulses. Klein adapted in real time, mapping how her mana shifted when she changed rhythm. He tested a new idea - extending a thin resonant thread from his sword tip to hers during a bind. The blades hummed together for a heartbeat, then Lirael's next strike lost half its power as the frequencies canceled momentarily.
He scored the final touch on her shoulder.
"Three to two," Klein said, lowering his blade.
Lirael exhaled sharply, then grinned - a rare, bright expression that cut through her usual seriousness.
"You cheated with that last trick. But I'll allow it. No one's ever made my own mana work against me like that. You turned a bind into a dampener."
Klein released his flows and studied the training sword in his hand. The steel carried a faint residual warmth from the resonance.
"Third observation," he said. "Weapons act as natural conductors when frequencies align. Prolonged contact allows temporary harmonic interference. In combat this could disarm or weaken an opponent's edge without direct force."
Lirael sheathed her blade and leaned against the weapon rack, arms crossed.
"You're dangerous, Second Young Master. Not because you're strong yet - you're still too light on power. But because you see patterns no one else bothers to measure. On the border we lose good knights to raiders who use crude mana bursts. If your method spread, entire units could train smarter instead of harder."
She paused, then added more quietly, "The Duke will hear about tonight. Servants talk. Word spreads fast when a talentless second son starts beating a border-trained swordswoman with theory."
Klein nodded. He had already calculated the likelihood.
"Data from live sparring fills gaps the library cannot provide. Your pulsed method, the way physical form amplifies flow, the interaction between blade and resonance - it refines my model. The family may see risk. I see variables worth testing further."
Lirael studied him for a long moment, her green eyes thoughtful.
"I'm no noble scholar. I fight because the border demands it. But if you ever need a partner who won't treat your experiments like heresy, find me here after dusk. I train alone most nights anyway."
She pushed off the rack and started toward the path leading back to the barracks.
"One more thing," she called over her shoulder. "The academy scouts arrive in two weeks for preliminary evaluations. They test every noble heir - even second sons who were previously dismissed. Word of your assessment this morning has already reached them through Master Harlan. Be ready."
Klein watched her disappear into the lantern-lit path. The night air felt cooler now, carrying the faint scent of night-blooming flowers still affected by his earlier experiments.
He remained on the grounds a while longer, replaying the spar in his mind. Physical movement and mana were not separate systems. They formed a single integrated circuit when properly synchronized. Lirael's border-honed style proved that repetition under real pressure created natural efficiency. His scientific approach could refine it further - turning instinct into repeatable, optimizable technique.
The world of Melros was built on power, yes. But power without understanding was wasteful. Nobles like Lirael survived on the frontier through practical adaptation. He would survive - and eventually surpass - by decoding the underlying rules.
As he walked back toward the main estate, Adrian's familiar figure appeared near the courtyard fountain, clearly waiting.
"You sparred with Lirael after dark?" Adrian asked, voice low but amused. "Servants saw the lights from the eastern grounds. Father has already been informed. He said nothing, but Mother looked worried again."
Klein allowed the faintest smile.
"Valuable data was obtained. Resonance under live pressure reveals interactions the assessment could not. Lirael's method complements mine. Together they suggest scalable combat applications."
Adrian shook his head, half laughing.
"You really do treat everything like an experiment. Even sword fighting with the best junior knight we have."
Klein glanced once more toward the darkened eastern grounds where Lirael had vanished.
"Because it is an experiment. And the results continue to improve."
The fountain water rippled softly behind them, reflecting scattered lantern light. Somewhere in the distance, the silver lilies still carried their subtle glow - a small reminder that change was already spreading beyond Klein's control.
The Royal Academy scouts were coming. Border tensions were rising. And now a practical swordswoman had taken personal interest in his unorthodox path.
Klein felt no pressure. Only the quiet certainty that each new interaction added another measurable layer to the system he was slowly mastering.
