The transition from the warm, lavender-scented nursery to the desolate, frost-covered stones of the northern training yard was brutal, sudden, and absolutely necessary.
Elara had wept, locking herself in her chambers for two days in protest. Duke Arthur had ignored her, ordering the inner courtyard sealed off from all non-essential personnel. The world of soft toys, silk cushions, and historical bed-time stories vanished overnight.
In its place stood Sir Kaelen.
It was dawn, three days after the Vanguard's arrival. The air in the northern yard was bitterly cold, the kind of chill that settled deep into the marrow of the bones. Kaiser stood in the center of the frosted cobblestones. He wore no velvet tunic or soft leather boots today; instead, he was dressed in a coarse linen training gi, his small feet wrapped in thick, unrefined hemp bindings.
He was shivering. His five-year-old body, despite its noble lineage, was entirely unaccustomed to the harshness of the elements. Yet, beneath the heavy dark-silk blindfold, his expression remained an impenetrable mask of absolute calm.
Control the core, Kaiser chanted internally, regulating his diaphragm. Short inhale through the nose, long exhale through the teeth. Let the cold pass through the skin, do not let it settle in the blood. Gradually, his violent shivering subsided. He achieved a state of thermal equilibrium, his breath pluming in the freezing air like the smoke of a dying ember.
Thirty paces away, Sir Kaelen sat cross-legged on a large, flat boulder. The scarred veteran had not moved an inch for an hour. To a normal observer, he looked like a statue draped in a dark cloak. To Kaiser's Absolute Senses, Kaelen was a coiled viper, his internalized Aura humming with a low, deadly frequency.
"You stopped shivering," Kaelen's gravelly voice cut through the silent yard. He didn't turn his head. "Most boys your age would be crying for their mothers. Or at least begging for a cloak."
"Tears freeze, Sir Kaelen," Kaiser replied evenly. "They are an inefficient use of body heat."
A low, raspy chuckle escaped the veteran's throat. Kaelen stood up, his joints popping loudly in the cold air. He walked toward Kaiser, his footsteps completely silent against the frosted stones.
"You have the mind of a killer trapped in the body of a whelp, young master," Kaelen said, stopping ten paces away. "Your father told me of your... lack of reaction to his Aura. And I felt your perception in the garden. You map the world through sound and pressure."
"I see the world as it truly is," Kaiser corrected softly. "Without the distraction of light."
"Bold words," Kaelen retorted, reaching under his cloak. "Let us test if your body can cash the checks your mind is writing."
With a flick of his wrist, Kaelen tossed an object through the air.
Kaiser's Absolute Hearing tracked it perfectly. It was a dense piece of wood, roughly two feet long, rotating end-over-end. He calculated its trajectory, its weight, and the exact moment it would strike the ground at his feet. He stepped back half an inch, allowing the object to clatter harmlessly onto the frost-covered stones.
"Pick it up," Kaelen ordered.
Kaiser knelt, his small fingers wrapping around the object. It was a bokken—a wooden training sword. The wood was unpolished oak, heavy and densely packed. To an adult, it was a light practice tool. To Kaiser's five-year-old arms, it felt like a lead pipe.
He stood up, struggling slightly to keep the tip of the wooden blade from dragging on the ground. He adjusted his grip, falling into a flawless, textbook martial arts stance from his previous life—feet shoulder-width apart, knees slightly bent, core tight, the sword held in a neutral middle guard.
Kaelen paused. Even without eyes, the veteran could read the displacement of air around Kaiser's body. He could sense the profound, unnatural perfection of the boy's posture.
"Who taught you that stance?" Kaelen demanded, his voice dropping an octave. "The Duke fights with a heavy broadsword. His stance is wide, built for overwhelming power. Yours is narrow. Built for parrying and precise counter-strikes. You have never held a blade before today."
"I have spent three years meditating in the dark, Sir Kaelen," Kaiser lied smoothly. "I simply arranged my bones in the manner that felt most structurally sound to support the weight of the wood."
Kaelen was silent for a long moment. Then, the veteran drew his own weapon—a slender, polished wooden cane that doubled as a training sword.
"Structural soundness means nothing if the foundation is weak," Kaelen said, his voice devoid of any mercy. "Defend yourself."
Kaelen didn't project killing intent. He simply moved.
To Kaiser's hyper-attuned senses, the attack was loud. He heard the shift of Kaelen's leather boots against the frost. He felt the sudden vacuum of air as the veteran lunged forward. He mapped the downward arc of Kaelen's cane aiming directly for his left shoulder.
Kaiser's mind, forged through twenty-eight years of lethal combat, reacted instantly. He pivoted his right foot, intending to side-step the blow and deliver a sweeping counter-strike to Kaelen's exposed ribs.
But his body betrayed him.
His five-year-old muscles, soft and undeveloped, could not generate the explosive fast-twitch kinetic energy his brain demanded. His pivot was sluggish. The heavy oak bokken in his hands felt like it was moving through thick mud.
Crack!
The wooden cane struck Kaiser's left shoulder with the force of a falling anvil.
Pain, hot and blinding, exploded through his collarbone. The sheer kinetic force of the blow lifted his tiny body off his feet, throwing him backward onto the hard, freezing cobblestones. The oak bokken clattered away from his numb fingers.
Kaiser lay on the ground, gasping for air as the wind was violently knocked out of his lungs. His left arm hung uselessly at his side, completely paralyzed by the localized trauma.
"You saw it coming," Kaelen stated coldly, standing over the boy. "You read my muscle twitches. You knew exactly where the strike would land. And yet, you are on the ground."
Kaiser gritted his teeth. He didn't cry out. He forced his breathing to stabilize, rolling onto his right side and slowly pushing himself up to his knees. The dark-silk blindfold remained perfectly in place, contrasting sharply against his pale, sweaty face.
"My... my body is too slow," Kaiser rasped, clutching his throbbing shoulder.
"Your body is weak," Kaelen corrected, his tone harsh and uncompromising. "You rely purely on your senses. You think because you can hear the arrow, you can dodge it. But in this world, young master, knowing is not enough. If your vessel cannot withstand the pressure of the environment, your mind will die with it."
Kaelen tapped his wooden cane against the frosted ground.
"In your nursery, you felt the ambient energy of the world. The scholars call it Mana. Mages draw it inward, poisoning their bodies in exchange for miracles. But Knights... Knights do the opposite. We generate Aura."
Kaiser, still kneeling, focused entirely on Kaelen's voice, pushing the pain in his shoulder to the back of his mind.
"Aura is not magic," Kaelen continued, his internalized energy suddenly spiking, causing the frost around his boots to instantly melt into steam. "It is the manifestation of physical will. It is life force, condensed and weaponized. It reinforces the bones. It accelerates the muscles. It turns a frail human body into a siege engine."
Kaelen pointed the tip of his cane at Kaiser's chest.
"Your father's Aura is an inferno. Mine is a silent razor. You possess neither. You are attempting to move a heavy carriage with the legs of a foal. Until you learn to ignite the furnace within your own core, your superior senses will only allow you to witness your own death in perfect detail."
Kaiser looked down at his small, trembling hands. In his past life, he had mastered 'Ki'—a subtle, flowing internal energy used to heal meridians and strike pressure points. But 'Aura' was vastly different. It required raw, explosive physical output. It required a vessel strong enough to handle the sheer pressure of its own generation.
And right now, his vessel was fragile.
"Pick up the sword," Kaelen commanded.
Kaiser took a deep, shuddering breath. His left arm was completely unresponsive, the muscles locked in defensive spasms. He dragged himself to his feet. Using only his right hand, he reached down and gripped the heavy oak bokken.
He didn't try to fall into a complex martial arts stance this time. He just stood there, holding the heavy wood with one hand, his pure white hair plastered to his forehead with cold sweat.
"Again," Kaiser whispered, his childish voice rough with pain, but entirely devoid of fear.
Kaelen's scarred mouth twitched into a terrifying, genuine smile. "Good. The Duke was right. You are a monster in the making."
For the next four hours, the northern courtyard echoed with the sickening thwack of wood striking flesh. Kaelen did not hold back. He beat the five-year-old heir mercilessly, striking his thighs, his back, his uninjured shoulder.
Every time Kaiser fell, he dragged himself back up. He stopped trying to counter-attack. He simply focused all his immense mental processing power on reading Kaelen's movements and attempting to condition his infant body to react a fraction of a second faster.
He was bruised, bleeding, and trembling from utter exhaustion, but beneath the dark-silk blindfold, Kaiser's mind was absolutely electric.
