To Kaiser, the transition from night to morning was not marked by the intrusion of light, but by a subtle shift in the world's frequency.
Before the roosters in the outer bailey could crow, the barometric pressure within the Duchy would change. The cold, heavy air of the Northern night would begin to warm, expanding against the stone walls with a microscopic, groaning resonance. The nocturnal insects would cease their rhythmic chirping, replaced by the rustle of avian feathers as the estate's hunting falcons shifted in their mews.
It was the morning of his first day as a three-year-old.
He was awake long before the heavy, rhythmic footfalls echoed down the corridor. He sat up in his large ironwood bed, the thick furs pooled around his waist. He adjusted the knot of his black silk blindfold—a habit he had developed, ensuring the seal was absolute.
The approaching footsteps were entirely different from his mother's sharp, authoritative clicks or the servants' terrified shuffling. These were measured, devastatingly heavy, and accompanied by the subtle clinking of overlapping steel plates.
Duke Arthur Warborn did not knock.
The heavy oak door swung inward, the iron hinges protesting slightly. The air in the nursery instantly grew dense, charged with the thrumming, violent crimson mana of the Duke.
Kaiser heard a sharp rustle of fabric from the adjoining room. His mother's heartbeat, previously locked in the slow, deep rhythm of sleep, spiked instantly. The door connecting her chambers to the nursery flew open.
"Arthur," Duchess Eleanor hissed, her voice thick with sleep but laced with instant, defensive hostility. "It is not yet dawn. What are you doing here?"
The Duke stepped fully into the room. He did not smell of crushed roses like Eleanor; he smelled of cold iron, leather, and the biting frost of the Northern winds.
"He is three years old today," the Duke's voice rumbled, deep enough to vibrate the water in the silver washbasin. "The grace period is over."
"He is a toddler!" Eleanor stepped between her husband and Kaiser's bed, her mana core flaring to life. The sudden heat clashed against the Duke's cold aura, creating a localized pressure front that made Kaiser's ears pop. "You will not drag him to the sparring rings to be battered by your brutes!"
"He is a Warborn," the Duke countered, immovable. "And he carries a curse that could level this estate if it slips its leash. A weak vessel shatters when filled with too much power. I will not allow my son to shatter, Eleanor. He must be forged."
"He is blind!" she cried out, the desperation cracking her commanding facade.
"He sees more than my master-at-arms," the Duke replied coldly. "You know this. You saw him dodge the sovereign. If he is to survive the politics of the capital, the machinations of the Holy Church, and the sheer weight of his own eyes, he cannot be soft."
The Duke took a step forward, his immense presence forcing Eleanor to brace herself. "Step aside, wife. I am taking him to the lower courtyard."
For a moment, Kaiser thought his mother might actually attack his father. He could hear the crackle of localized lightning beginning to form around her fingertips. The air grew dangerously thin.
"Mother."
Kaiser's small voice, calm and perfectly modulated, cut through the suffocating tension.
Both of his parents froze. Kaiser pushed the heavy furs aside and swung his short legs over the edge of the tall bed. He didn't wait for a servant to assist him. He slid down, his bare feet hitting the cold stone floor with a soft pat.
He walked precisely to where his mother stood, navigating around a scattered pile of wooden blocks with flawless spatial awareness. He reached out, his tiny hand finding the rich velvet of her robe.
"It is alright," Kaiser murmured, tilting his blindfolded face up toward her. "I want to go with him."
Eleanor's breath hitched. She dropped to her knees, pulling him into a tight, desperate hug. Her heart was beating frantically against his chest. "Kaiser... you don't understand. The training... your father does not know how to be gentle."
"I am not made of glass, Mother," Kaiser replied softly, patting her back. And it was true. Thanks to the apothecaries his father had mandated, his bone density was absurd for his age. His thirty-two-year-old mind was more than prepared for discipline; in fact, he craved it. The coddling of the nursery was beginning to stagnate his development. He needed to test his absolute senses in a dynamic environment.
Eleanor held him for a long moment before slowly releasing him. She stood up, glaring at the Duke with a venomous intensity.
"If he bleeds," she whispered, her voice a promise of absolute destruction, "if you break even a single bone in his body, Arthur... I will burn your precious armory to the ground."
The Duke offered no reassurance, merely a curt nod. He turned his massive, armored back. "Follow, boy."
Kaiser fell into step behind his father.
The journey to the lower courtyard was an acoustic descent into a harsher world. They left the thick, sound-dampening carpets of the family wing, moving onto the bare, echoing stone of the servant corridors, and finally out into the biting cold of the open air.
The lower courtyard was vast. To Kaiser's absolute hearing, it was a wide, flat expanse of hard-packed earth, bordered by high, thick walls of granite. There were no tapestries here, no soft edges. Only the heavy wooden weapon racks, the dense straw of the archery targets, and the whistling of the wind sweeping down from the mountains.
The Duke stopped in the exact center of the yard.
"The men have been cleared from this sector," the Duke said, his voice carrying effortlessly across the open space. "For the next hour, you are not the Duke's son. You are a piece of iron, and I am the hammer."
Kaiser stood ten paces away. The biting frost seeped through his thin wool tunic, but he commanded his body not to shiver. He focused his hearing, expanding his acoustic map until it touched every wall, every weapon rack, every grain of dirt in the courtyard.
"You dodged a coin," the Duke continued, slowly drawing something from his belt. It wasn't steel. It was a thick, heavy rod of solid ironwood, smoothed by years of use. It hummed slightly as it cut through the air. "A coin is small. It follows a predictable trajectory. Intent is different."
The Duke began to walk. He moved in a slow, wide circle around Kaiser.
Crunch. Crunch. Crunch. The heavy armored boots pulverized the hard earth.
"A man with eyes can see a blade rising," the Duke rumbled, his voice shifting in origin as he circled. "He can see the tension in an opponent's shoulders. You do not have that luxury. If you rely only on hearing the whistle of the blade, you will die. The blade is too fast."
Kaiser turned slowly on his heel, keeping his face perfectly aligned with the sound of his father's footsteps.
"You must not listen for the weapon," the Duke instructed, stopping directly behind Kaiser. "You must listen for the intent. The micro-shift in weight. The sudden intake of breath. The friction of muscle against bone before the strike is even launched."
Total silence fell over the courtyard. The wind died down.
Kaiser focused. He didn't listen for the ironwood rod. He listened to the massive, roaring crimson core within his father's chest. He listened to the Duke's heartbeat.
Thump... thump... thump...
The rhythm was steady. Calm. Then, subtly, the interval between the beats shortened by a fraction of a millisecond. The leather of the Duke's right gauntlet creaked, a sound so soft only a dog—or Kaiser—could hear it. The heavy, kinetic energy of the Duke's mana suddenly spiked, rushing from his core into his right arm.
He's stepping off his left foot. The strike is coming from high above the right shoulder.
Kaiser didn't wait for the rod to cut the air. The moment the Duke's muscles contracted, Kaiser stepped sharply to the left and pivoted.
Whoosh—CRACK!
The ironwood rod slammed into the hard-packed earth exactly where Kaiser's right shoulder had been a fraction of a second before. The impact sent a localized tremor through the ground that vibrated up Kaiser's legs.
If it had hit him, it would have shattered his collarbone instantly. His mother's threats had meant nothing; the Duke was not holding back.
Kaiser stood calmly, his blindfolded face angled toward the crater the rod had just made in the dirt.
The Duke exhaled, a slow, rumbling sound of immense satisfaction.
"Again," the Duke commanded, ripping the rod from the earth.
For the next hour, the courtyard became a deadly dance of vibration and movement. The Duke did not speak another word of instruction. He simply attacked.
He struck from the front, from the sides, from the blind spots a normal person would have. He swung horizontally, vertically, thrusting with the blunt tip of the wood.
Kaiser did not try to block. A three-year-old body, no matter how magically fortified, could not parry the strength of a fully grown warlord. He only evaded.
To an observer, it would have looked like a horrific scene of child abuse—a massive, armored giant ruthlessly trying to bludgeon a tiny, blindfolded boy. But to a master of combat, it was a display of impossible, supernatural grace.
Kaiser moved like a ghost. He didn't flinch. He didn't stumble. He interpreted the friction of his father's armor, the shift of the gravel, and the pulsing of the crimson mana to predict the exact path of the weapon before it was even in motion. He ducked under sweeping strikes by mere millimeters. He swayed away from thrusts, letting the displaced air ruffle his dark hair.
He was breathing heavily now. His tiny lungs burned, and his underdeveloped muscles screamed in protest. His thirty-two-year-old mind was executing flawless calculations, but his biological hardware was reaching its limit.
One more, Kaiser realized, hearing the catastrophic buildup of mana in his father's core. He's going for a wide, sweeping arc. Maximum speed.
The Duke's boots dug into the earth. The leather creaked. The mana roared.
Kaiser didn't dodge backward; the arc was too wide. Instead, he lunged forward, stepping directly into the Duke's guard, closing the distance before the swing could generate its lethal momentum. He dropped to one knee, sliding under the heavy ironwood rod as it whistled fiercely over his head.
As he slid, Kaiser reached out his small hand and placed it flat against the cold steel of his father's breastplate.
Tag.
The Duke froze mid-swing.
The courtyard was dead silent, save for the ragged, exhausted panting of the three-year-old boy kneeling at the warlord's feet.
Kaiser's muscles gave out. He slumped back, sitting on the cold dirt, his chest heaving. He had pushed his infant body far beyond its natural parameters.
Duke Arthur Warborn slowly lowered the ironwood rod. He looked down at the tiny handprint left in the morning frost on his breastplate. If the boy had held a dagger, and possessed the strength to drive it, he would have pierced the Duke's heart.
The Duke dropped the rod. He knelt down, the joints of his armor protesting, until he was eye-level with his son. He reached out with his massive, gauntleted hand.
Kaiser tensed, anticipating a blow, or perhaps assistance up.
Instead, the Duke's hand moved to the back of Kaiser's head. He checked the knot of the black silk blindfold, ensuring it had not slipped a single fraction of a millimeter during the hour of intense evasion.
It was secure. The Void was contained.
"Your stamina is pathetic," the Duke said, his voice flat and unyielding. "Your muscles are weak, and your strides are too short."
Kaiser nodded silently, his chest still heaving. He knew.
"But your mind..." The Duke paused, the crimson mana around him settling into a profound, heavy calm. "Your mind is a fortress."
The Duke stood up, casting a long shadow over Kaiser.
"Tomorrow, we begin an hour earlier," the Duke commanded, turning his back to walk toward the armory. "You will not eat until you can evade me for two hours without falling."
Kaiser sat in the dirt, listening to his father's heavy footsteps fade into the distance. His body was bruised, battered, and utterly exhausted.
