The pungent, earthy aroma of crushed Kingsfoil and bitter root filled the lavish bathroom of the inner estate. The air was thick with steam, but it offered no warmth to the bruised, trembling boy sitting on the edge of the marble tub.
Kaiser was five years old, yet his torso looked like a canvas painted in violent shades of violet, black, and sickly yellow. Sir Kaelen had targeted non-lethal areas—the heavy muscle of the thighs, the broad span of the back, the meat of the shoulders—but on a child's frame, the damage was horrifying to behold.
"Hold still, my sweet boy," Elara whispered, her voice tight with suppressed sobs.
She gently dabbed a warm, foul-smelling medicinal paste onto a particularly nasty welt across Kaiser's ribs. Even her feather-light touch sent a shockwave of localized agony through his highly attuned nervous system, but Kaiser did not flinch. He sat with his spine perfectly straight, his dark-silk blindfold contrasting starkly against his pale, sweaty skin.
He could hear the rapid, chaotic fluttering of his mother's heartbeat. It was a sound of pure, unadulterated heartbreak.
"It looks worse than it is, Mother," Kaiser said calmly, his small hands resting loosely on his knees. "The bruises are superficial. Sir Kaelen struck the muscle bellies. He deliberately avoided the joints and the spine. My mobility is unimpaired."
Elara's hand froze. The heavy, warm washcloth dripped into the bathwater with a soft plop.
"You sound like him," she choked out, a tear finally escaping and splashing against Kaiser's bare shoulder. "You sound just like your father. Analyzing your own injuries as if you are a soldier reporting to a general. You are five, Kaiser. You should be crying. You should be angry."
Kaiser turned his blindfolded face toward her. He reached out with a small, bruised hand, flawlessly tracking the origin of her tear, and wiped her cheek.
"Pain is simply information, Mother," he explained gently, using the philosophy that had kept him sane in his past life. "It is the body's way of mapping its limits. If I cry, I expend energy. If I am angry, I lose my focus. I must remain empty to learn."
Elara let out a long, shaky breath, pulling him into a careful embrace, terrified of hurting him further. She smelled of lavender and deep sorrow. "I will speak to Arthur again," she murmured into his white hair. "I will beg him to stop this."
"No," Kaiser replied, his childish voice suddenly carrying a weight that made Elara stiffen. "Do not beg him, Mother. I asked Sir Kaelen to show me the limits. I chose this."
Before she could argue, Kaiser slipped off the edge of the tub. His legs trembled slightly beneath his weight, but he locked his knees, forcing the weak muscles to obey his will. A maid had laid out fresh, warm sleepwear on a stool. He navigated to it smoothly, his mind mapping the room with absolute precision despite his physical exhaustion.
"Goodnight, Mother," he said softly, bowing his head slightly before turning and walking back to his chambers.
Once the heavy oak door of his bedroom clicked shut, Kaiser abandoned the flawless aristocratic posture. He leaned heavily against the wooden panels, gritting his teeth as a wave of nausea washed over him. His body was screaming.
He shuffled toward the center of the room and collapsed onto the thick fur rug, ignoring his lavish four-poster bed. He assumed the lotus position, crossing his aching legs, and rested his hands on his knees.
I am too slow, he thought, the frustration finally bleeding through his stoic facade.
He closed his eyes beneath the dark-silk blindfold and turned his perception inward. In his previous life, he had been a master of 'Ki'. Ki was like water. It flowed through the meridians, healing the body, enhancing reflexes, and striking outward through precision and flow.
But this world didn't operate on water. It operated on fire.
Sir Kaelen's energy—this 'Aura'—was completely different. When Kaelen moved, he didn't flow. He exploded. Aura was the physical manifestation of life force, violently pressurized within the core and forcefully expelled into the muscles and bones to turn the body into steel.
Kaiser slowed his breathing. Inhale. One... two... three... Exhale. One... two... three...
He visualized his own core, the center of his chest. It was cold. Weak. He tried to summon the familiar flow of Ki, but the mana of this world heavily suppressed it. He needed to adapt. He needed to forge the spark he had felt in the training yard.
Aura is not given, he recalled Kaelen's harsh lesson. It is demanded by the flesh when it refuses to die.
Kaiser visualized a heavy, suffocating weight pressing down on his chest. He imagined the immense, terrifying heat of his father's aura. He imagined the razor-sharp killing intent of Kaelen's wooden cane. He took all the fear, all the physical agony radiating from his bruises, and instead of letting it scatter, he mentally corralled it into his center.
Pressurize, he commanded his body.
He clenched his internal muscles. He forced his heart rate to slow even further, condensing his blood flow.
Deep within the darkness of his internal void, a microscopic flicker of heat ignited. It was infinitesimally small—the size of a pinprick—but it was there. It wasn't the flowing river of his past life; it was a dense, vibrating ember of raw physical will.
Kaiser held it for exactly three seconds before his concentration slipped and the ember vanished, leaving him gasping for air, sweat pouring down his pale face.
He fell forward onto the fur rug, exhausted but smiling.
Found it.
The next month was a blur of freezing mornings, shattering wood, and the relentless, agonizing refinement of the spark.
Winter descended upon the Warborn estate with brutal indifference. The northern training yard was permanently blanketed in a thick layer of snow. The servants whispered that the young master was being tortured to death by the blind assassin, but no one dared intervene. Duke Arthur's orders were absolute.
"Your footwork is sloppy," Kaelen's raspy voice cut through the howling winter wind.
Kaiser knelt in the snow, his linen gi soaked through, shivering violently. He gripped his heavy oak bokken with both hands. His knuckles were raw and bleeding from the cold and the friction of the wood.
"You are reading the wind, not my muscles," Kaelen circled him like a starved wolf, his own footsteps making absolutely zero sound against the crunchy snow. "The wind is chaotic. It will lie to you. Focus your hearing on the friction of my joints. Listen to the blood pumping in my veins."
Kaiser closed his eyes beneath his blindfold, shutting out the roar of the wind. He sank his consciousness into the earth. Through the thick layer of snow, he felt the stone beneath. He waited.
There. A subtle, microscopic shift in pressure to his blind right side. Kaelen was pivoting his hip.
Kaiser didn't try to dodge. His body was still too slow to outrun the veteran's strikes. Instead, he forced his consciousness inward. He found the tiny, vibrating ember of heat in his core that he had been nurturing for thirty days.
Ignite!
Kaiser commanded his body to pressurize. For a fraction of a microsecond, the ember flared. A tiny, almost imperceptible surge of Aura flooded into his right arm.
He swung the oak bokken upward, intercepting Kaelen's descending cane.
CRACK!
The impact rang out like a gunshot in the frozen yard.
This time, Kaiser was not thrown backward. The heavy oak sword in his hands splintered and shattered under the immense force of Kaelen's strike, but Kaiser's feet remained firmly planted in the snow. The residual kinetic shockwave traveled down his arms, but his right arm—reinforced by that momentary pulse of Aura—did not break.
Silence fell over the courtyard, save for the howling wind.
Kaelen stood with his cane extended, the shattered remnants of Kaiser's training sword scattered in the snow between them. The veteran assassin slowly lowered his weapon.
Even through Kaelen's scarred, empty eye sockets, Kaiser could feel the weight of the man's intense scrutiny.
"You felt it," Kaelen stated. It wasn't a question.
"Yes," Kaiser breathed out, white vapor pluming from his lips. His right arm was completely numb, the tiny reserve of Aura entirely depleted, leaving him utterly drained. "It felt like... trying to swallow a burning coal."
A slow, terrifying grin spread across Kaelen's scarred face.
"Aura is fire, young master," the assassin rasped, reaching under his cloak to toss Kaiser a fresh, unbroken wooden sword. "And today, you finally learned how to spark the flint. But a spark will not keep you warm in the dark."
Kaiser bent down, his muscles screaming in protest, and picked up the new weapon. He settled back into his narrow, flawless stance. The bruises from yesterday throbbed in rhythm with his heartbeat, but his mind was crystal clear.
"Then teach me how to build an inferno, Sir Kaelen," Kaiser said, his childish voice steady against the winter storm.
"With pleasure," Kaelen replied, and lunged.
