"Go!" the King roared, his voice bouncing off the high cliffs like a thunderclap.
The sound rattled inside Kairo's skull. He stood at the base of the mountain trail, squinting against the blinding glare of the midday sun. Sweat was already dripping from his eyelashes, stinging his eyes and tasting of salt. The air was dry, smelling of baked dust and dry pine needles.
Around his ankles, the iron cuffs dug directly into the leather of his boots. Each step he took felt like dragging a pair of anchor chains through wet clay.
This is a tutorial level, Kairo thought, his knuckles turning white as he clenched his small hands. This has to be the tutorial. But usually, you don't start a game with thirty kilograms of scrap metal strapped to your shins. No way this is legally balanced.
The path ahead was a steep, jagged scar of grey shale that snaked upward toward the cloud line, flanked by towering, gargantuan slabs of ancient bedrock. Below him, the palace courtyard was already shrinking, the tiny figures of soldiers looking like wooden toy models on a table. He could hear the distant, faint clack-clack of their wooden practice swords, a rhythmic sound that seemed to mock his slow progress.
He glanced down at his nine-year-old legs. They were shaking.
I used to complain about walking to the convenience store for chips, he reminded himself, trying to swallow the lump of dry panic in his throat. Now I have to climb a literal geological monument. Great. Fantastic.
Kairo lunged forward.
His boots slid on the loose gravel, sending a cascade of small pebbles clattering over the sheer edge of the drop. He forced his right leg up, the cold iron biting through his socks, pinching the skin around his Achilles tendon. A sharp, burning ache blossomed in his calves, shooting straight up to his lower back.
He took three steps. Four. Five.
The heat in his chest grew hotter, a stubborn spark behind his ribs that seemed to flare with every ragged breath he took. He squeezed his eyes shut, trying to block out the searing pain in his thighs.
Just like those training arcs, he muttered in his head. Just run. Don't look up.
He looked up. The peak still seemed miles away, shimmering in the heat haze.
"Don't lose your footing, boy!" the King shouted from below, his towering silhouette standing perfectly still in the center of the dusty training grounds. "Keep your eyes on the path!"
Kairo didn't have the breath to reply. His lungs felt as if they were lined with crushed glass. On his tenth step, his toe caught the edge of a jagged rock.
The world tilted violently. He tumbled forward, his knees slamming hard against the sharp shale. His wooden practice sword clattered away, rolling into a patch of dried thistles. Kairo slid a few feet down the slope, his palms scraping raw against the gravel.
He lay there for a second, his forehead pressed against the dirt. The warm, metallic smell of blood mixed with the dusty earth. His palms were oozing, red tracks mapping across his dirty skin. Tears of pure frustration welled in his eyes, hot and blurry. His tiny body was screaming at him to stop, to just roll over and let the guards carry him back to his soft mattress.
Why am I doing this? he thought, his chest heaving as he sobbed quietly. I didn't ask to be here. I didn't ask to be a prince.
Then he remembered his father's eyes from earlier. Not the roaring commander, but the man who had knelt in the dirt, smelling of sour ale and leather, telling him that kindness without strength was just a fancy way of dying. In this world, weakness wasn't just a stat penalty—it was a death sentence.
"No," Kairo gasped, his voice cracking like dry wood. "No. Not yet."
He slammed his bloodied fists into the dirt, using the momentum to force his knees under his chest. Shaking, his small frame trembling like a leaf in a storm, he pushed himself back onto his feet. He didn't pick up the wooden sword. He just locked his eyes on the trail.
One painful yard at a time, he dragged his body upward. The sun beat down on his neck like a physical weight, but he kept moving. His vision blurred at the edges, turning the grey rocks into a swirling vortex of shadow and light.
When his boot finally cleared the final ridge, a cool, biting wind slapped his face, carrying the scent of high-altitude snow. He collapsed onto his rear, his chest pumping like a bellows, and let out a weak, breathless laugh.
"I... I did it..."
"Don't get comfortable!" the King's voice boomed, magically carrying up the mountain breeze. "Three more runs, Kairo! Down and up!"
Kairo's jaw dropped. He's joking. Please tell me he's joking.
He wasn't.
The next three hours were a blur of agonizing friction. Kairo dragged himself down the treacherous slope, his knees buckling with every step, only to turn around and face the climb again. His boots grew slick with his own blood where the iron had sliced through his skin. By the fourth ascent, he wasn't even thinking in sentences. His mind had retreated into a survival loop—left foot, right foot, breathe, don't fall.
Deep within his chest, the small, cold ember of the shadow contract thrummed in rhythm with his heartbeat, providing a tiny, icy thread of energy that kept his muscles from tearing completely apart. It was the only thing keeping him conscious.
With a final, desperate cry that sounded more like a cub's whimper, Kairo drove his legs through the last stretch of dust and tumbled back onto the flat ground of the courtyard.
"Father..." Kairo wheezed, his vision fading to gray. "I... did..."
His knees gave out completely. He collapsed face-first into the loose dirt, the cool soil pressing against his burning cheek.
A pair of weathered leather boots crunched slowly across the gravel, stopping right in front of Kairo's nose.
For a long moment, the only sound was the wind whistling through the courtyard battlements and Kairo's own shallow, ragged breathing. Then, a towering shadow fell over him, blocking out the merciless glare of the sun.
The King knelt down. He didn't offer a hand to help the boy up, but his large, scarred hand came down gently on Kairo's head, his rough fingers threading through the boy's sweaty hair.
"Well done, my son," the King said, his voice unusually quiet, carrying a deep, resonant pride. "You didn't just climb a mountain today. You climbed your weakness. Remember this pain. It is the clay from which a ruler is shaped."
Kairo tried to nod, his cracked lips twitching into a tiny, exhausted smile. Then, the gray borders of his vision rushed inward, and the world went entirely black.
The next morning, Kairo couldn't move.
He lay flat on his back in the massive bed, staring blankly at the dark timber beams of his ceiling. Every single muscle fiber in his body felt as if it had been unraveled, soaked in vinegar, and stitched back together with iron wire. Even blinking felt like an athletic achievement.
I am dead, he thought, his eyes tracking a lazy spider spinning a web in the corner. I have died of muscle soreness. What an incredibly embarrassing way to go.
He let his eyelids drift shut, determined to sleep for the next three days—
Ding!
The sharp, crystal-clear chime rang right inside his ears.
Kairo's eyes snapped open.
A glowing, translucent pane of pale blue light was hovering in the air directly in front of his face. Tiny, golden runes rippled across its glassy surface, forming crisp, unmistakable letters.
[Welcome, Player.] Your growth has been acknowledged.
Kairo stared at the floating window, his sore jaw dropping.
No freaking way, he thought.
The morning had begun in silence, but it was a heavy, suffocating kind of quiet. Through the tall, narrow arrow-slits of the bedchamber, the pale light of dawn filtered in, casting long, barred shadows across the stone floor. The air smelled faintly of cold ash from the hearth, mingled with the bitter tang of wintergreen ointment that the servants had smeared over Kairo's aching calves while he slept.
Kairo sat cross-legged in the center of the massive, four-poster bed. The linen sheets beneath him were rumpled and damp with his own dried sweat. Every minor movement—the slight tilt of his neck, the simple flexing of his toes—sent a dull, throbbing ache radiating through his joints.
Hovering precisely eighteen inches from his nose was the impossible.
A translucent pane of pale blue light hummed in the dim room. The edges of the rectangle vibrated with a soft, steady frequency, casting a cool azure glow over his scraped hands and the white wool of his blanket.
[Name: Kairo] [Class: ???] [Level: 1] [Strength: 5] [Agility: 4] [Vitality: 6] [Intelligence: ???]
"This... this is like an RPG," Kairo whispered, his voice dry and raspy. He reached out a finger, his raw nail almost touching the light. "But why are there question marks? Hmm... I guess I have to level up to see my actual stats."
Before he could even attempt to swipe the window away, a soft chime—like the strike of a tiny silver fork against crystal—echoed behind his temples. The blue glass rippled, the original text melting away to reveal clean, sharp gold lettering.
[New Quest Assigned: Become Worthy of the Sword] [Objective: Master the fundamental forms of the wooden blade.] [Reward: Skill - Beginner Swordsmanship]
Kairo bolted fully upright. The sudden movement caught the raw tendons in his lower back, and he winced, a sharp hiss escaping his teeth. He ignored the flare of physical pain, his heart slamming against his ribs like a trapped bird.
"Quests? Rewards?" He stared, his pupils dilated in the blue glow. "This... this is insane!"
For five seconds, the interface remained suspended in the quiet air, a perfect, glowing promise of effortless progression. A checklist for destiny.
Then, the blue light stuttered.
The steady hum of the system turned into a high-pitched, grinding whine that made Kairo's ears ring. The neat golden borders of the screen fractured, spider-webbing with dark, jagged lines. The letters began to spin, corrupting into unintelligible, blocky code that bled down the interface like wet ink.
"Eh? W-What's happening?!" Kairo gasped, throwing his hands up as if to catch the breaking pieces.
[ERROR. SYSTEM INTEGRITY COMPROMISED.] [MALFUNCTION IN CORE LOGIC...]
With a soundless, violent crack, the blue window shattered. The fragments didn't fall; they dissolved into tiny, sparkling motes of dust that vanished before they hit the bedsheets.
Kairo lunged forward, his hands grasping at the empty air. "N-no...! Come back! System, open! Status window—!"
The room was dead silent. The wind moaned softly through the high stone battlements outside, but within the four walls of his chamber, there was nothing. No light. No magical assistance. The crushing reality of his bruised, nine-year-old body settled back over him like a lead weight. Despair, cold and sharp, clawed up his throat. His shoulders slumped, his chest heaving with a shallow, panicked breath.
Ding.
The sound was different this time. It wasn't the clean chime of a bell; it was the heavy, ominous clang of iron striking an anvil.
A new window materialized. It was smaller, narrower, and edged in a deep, bruised crimson that seemed to swallow the morning light around it. The air in the room instantly grew colder, the scent of old parchment and dry iron filings filling Kairo's nose.
[Listen, Kairo.] [Do you think strength is given? Do you think shortcuts exist?] [Foolish child. Your previous system will never return.] [You will suffer. You will bleed. Only then will you become strong.]
Kairo froze, his bare knees pressed together as he stared at the crimson text. His mouth felt as dry as the ashes in the grate. "W-what...? Why...?"
The red letters shifted, typing themselves out with a deliberate, agonizing slowness.
[I will not grant you strength. You must EARN it.] [Now then... study.]
Before Kairo could speak, the space directly above his lap distorted. The air shimmered, and a heavy, solid object materialized out of the empty air. It dropped with a resounding, breath-knocking thud onto his bare thighs.
Kairo winced, looking down. It was a massive, leather-bound folio, thick enough to blunt a sword strike. The cover was a deep, curdled crimson, the leather pitted and old, smelling of cedarwood and very old library dust. Embossed across the front in heavy gold leaf were the words:
How to Be a Good Leader
Kairo blinked, his mind struggling to bridge the gap between a magical fantasy system and a textbook. "A... a book?!"
The crimson window flickered once more, the text appearing beneath the first block with an almost mocking promptness.
[Your first trial is knowledge. No warrior, no king can rise without wisdom.] [Begin studying. Fail to learn... and you will never grow.] [You may summon books. That is all this system will grant.] [No powers. Only knowledge.]
The crimson window dissolved into a thin wisp of dark red smoke that smelled faintly of sealing wax before vanishing entirely.
Kairo sat in the middle of the drafty room, his fingers slowly coming down to rest on the corners of the heavy tome. The gold lettering was cold under his fingertips. His heart pounded in his ears, but the frantic panic of moments before was beginning to cool, hardening into a quiet, stubborn focus.
"...So... no shortcuts... huh?" he whispered to the empty room.
He ran his thumb over the grain of the red leather. The book was incredibly heavy, but as he turned the first thick, parchment page, the dry rustle of the paper felt realer than any glowing blue light ever had. There were no stat points to save him from a blade. There was only what he could put into his own head, and what he could force his body to endure.
He bent his head, his eyes tracking the dark, handwritten ink of the first chapter.
"A true leader must never turn away from the cries of his people..."
Kairo lost himself in the text. He read through the stiffness in his neck, through the slowly warming light of the morning as it shifted across the grey stone floor. The book detailed the ancient logistics of grain distribution during winter blockades, the psychological burden of sentencing a man to the gallows, and the quiet, heavy mathematics of a siege. It was dry, brutal, and entirely devoid of magic.
BANG!
The heavy oak double doors of his chamber didn't just open; they recoiled against the stone walls with a force that rattled the iron hinges.
Kairo jumped, his hand instinctively clutching the edge of the crimson book to keep it from sliding off his lap.
The King stood in the threshold. He did not look like a father returning from a morning walk; he looked like war itself. He was clad in his massive, midnight-black plate armor, the metal chased with veins of dark crimson that seemed to catch the morning sun like fresh veins of ore. His heavy cloak, dyed the color of dried bull's blood, billowed behind him in the drafty corridor.
The air in the bedroom grew instantly thick, smelling of horse sweat, oiled iron, and the cold frost of the outer courtyard.
"Kairo," the King said. His voice was a low, scraping gravel that vibrated through the floorboards and straight into Kairo's shins. He didn't look at the book in the boy's lap. He didn't ask how his muscles felt after the brutal climb. "We must hurry."
He turned on his heel, his heavy iron greaves clanking against the stone as he strode back down the gallery, leaving the doors wide open.
Kairo hesitated for a single beat. He closed the book with a heavy clap, slid his small feet out of the bed, and winced as his raw soles touched the freezing granite floor. The trial of the mountain was over, but as he rushed to pull on his boots, he knew the real test was just beginning.
