The next few days passed in a quiet, almost surreal blur.
The recovery ward was tucked away in a cold stone wing of the facility, where the faint scent of sharp chemical antiseptic blended uncomfortably with dried herbs. Vivienne came by regularly to inspect my wounds. At first, her visits were purely clinical—she would check my bandages with brisk, efficient movements and leave without a word. But as the days wore on and I initiated a few cautious exchanges, a strange dynamic settled between us.
We quickly realized that we operated on a similar wavelength. Neither of us cared for mindless chatter. We spoke in short, functional sentences, trading bits of practical information.
Truthfully, I didn't have much to offer her. What kept her coming back was a morbid fascination with my body. My unnaturally fast recovery rate had hooked her curiosity like a scientist stumbling upon an anomaly. But given her profession—and her distinct lack of empathy—I quickly realized she had more than a few screws loose.
"Would you mind if I made a small incision?" she asked me nonchalantly one afternoon, tapping a finger against her chin as if requesting a cup of tea. "Just a quick cut. I want to observe the cellular speed of your healing process in real time."
"Absolutely not," I replied instantly.
That didn't stop her, of course.
Twice over the following nights, I jolted awake in the dark to find a silhouette looming over my bed. Moonlight cut across the cold floorboards, reflecting off the surgical steel of a scalpel held inches above my chest. She was leaning down, eyes gleaming with quiet intensity, ready to slice into me while I slept.
Needless to say, I didn't sleep in peace for the rest of my stay. Every creak of the floorboards set my heart racing. If someone told me she moonlighted as a shadowy assassin for the state, I wouldn't have doubted it for a second.
Through our brief exchanges, I managed to piece together a few details about where I was. Vivienne belonged to the medical unit of the Brithenian Royal Army, and this facility was operated by the Ashen Cell—a specialized military division dedicated to rooting out internal threats to the Empire. She dropped other terms too, though most flew right over my head. She frequently mentioned something that sounded like Arke... or Arce? I couldn't grasp the exact pronunciation.
I refrained from probing too deeply to avoid raising suspicion. But from the tone of her voice, it sounded like some form of extraordinary power native to this world. I'll look into it once I'm out of here, I told myself.
By the fourth day, Vivienne and I had reached a sort of tacit understanding. We were like awkward workplace colleagues—a terrible description, but I couldn't think of anything more fitting.
Meanwhile, Fleur visited almost every day. Despite the hospital providing mandatory rations—bland, lukewarm broths—she insisted on bringing me homemade meals four times a day.
Even though I was confined to the creaky iron bed, a quiet sense of peace slowly settled over me. My previous life had ended in a horrific, bloody tragedy; compared to that nightmare, this quiet room felt almost like a soft dream.
The only dark clouds hovering over these four days were the visits from Kane and the recurring nightmares.
Kane, a sharp-eyed boy from the military unit, came by to interrogate me about how I ended up in the kidnappers' hideout. I feigned total amnesia regarding the events of the abduction, offering vague answers wrapped in confusion. Surprisingly, he bought it without pushing further. It was as if he could somehow sense the absolute truth behind my lied composure—or perhaps he had some kind of built-in lie detection ability.
Then came the nights. Every single night, the moment my eyes closed, the murmurs returned.
They were head-shattering, incoherent whispers that vibrated deep within my skull, identical to the agonizing noise I heard when I first woke up in this world. The sheer, searing pain left me gasping for air in the pitch black. It was a torture I couldn't adapt to, no matter how hard I tried.
I don't think I ever will.
"Congratulations. Today is your discharge day. I am so very happy for you," Vivienne announced on the morning of the fourth day, her voice utterly flat and her face wearing the single most disappointed expression I had ever seen.
"Really? You certainly don't look very happy..." I muttered, pulling myself up to a sit.
"Well, watching your most interesting lab rat walk out the front door without getting to dissect it isn't exactly a pleasant feeling," she replied dryly.
"Is that so…"
Did she just call me a lab rat?
The heavy wooden door burst open. Fleur dashed into the room carrying a vibrant bouquet of fresh red roses, their sweet fragrance immediately cutting through the stale hospital air.
"Congratulations, Brother!" she cried out.
She practically threw herself across the bed, wrapping her arms tightly around Arthur. He smiled, feeling the warmth of the moment, and gently patted her soft hair.
"Guess what?" Fleur said excitedly, pulling back with beaming eyes. "I prepared a feast for us back home! I even baked your favorite honey bread to celebrate your recovery!"
"Really? You can cook?" Arthur asked, genuinely surprised given how young she was.
A flush of pink rose to her cheeks as she looked down shyly. "Well... I'm not the best cook in Athen. I just tried to follow what you taught me before. I don't know if it'll taste any good..."
"I'm sure it'll be amazing," Arthur reassured her with a playful grin, intentionally puffing out his chest. "After all, you learned from the master himself. Need I remind you of my world-class culinary expertise?"
Fleur burst into a bright, melodious giggle, her lingering self-consciousness melting away instantly.
Vivienne stood by the window, watching the exchange with a hand resting on her hip. She clearly had zero patience for tender family reunions, but the mention of food seemed to spark her interest.
"Enjoy your little festival," Vivienne said in her usual stoic drone. "Just keep your diet clean. I'd hate for my precious lab rat—patient—to end up back in my ward with a stomach bug."
She then leaned in slightly, muttering under her breath in a low whisper that she clearly thought was quiet: "Then again, maybe a stomach bug wouldn't be so bad. If he gets an infection, I'll finally have a reason to cut him open..."
I can hear you! Keep those terrifying thoughts to yourself! What kind of doctor jumps straight to abdominal surgery over an upset stomach?! She really is a complete psycho...
After signing the discharge papers Vivienne handed over, Arthur swung my legs out of bed. He changed out of the faded hospital gown into the clothes Fleur had brought along.
The garments were far from luxurious—coarse, stiff fabric with uneven stitching that most people in higher society would look down upon. But to Arthur, having spent a past life rooted in soul-crushing poverty, these clean, warm clothes were more than He could ever ask for.
"Oh, right," He said, adjusting the collar of the shirt. "I've been in your care for four days, but I never got the chance to meet Officer Gerd. I haven't even properly thanked him for saving my life. Is it really alright if we just leave without saying goodbye?"
Vivienne didn't hesitate with her answer. "Of course. Gerd and his team are constantly deployed. It's far better if you don't look for him. Frankly, having civilians show up unannounced would just be a bother."
"I see..."
Arthur took one last look around the cold medical room, grabbed Fleur's hand, and walked out into the bright daylight.
Stepping across the threshold was like crossing an invisible boundary. One moment Arthur and Fleur were standing inside the cold, oppressive quiet of the Ashen Cell facility; the next, they were plunged headfirst into the chaotic roar of a crowded city street.
Arthur turned around instinctively, only to find a plain, unbroken brick wall where the heavy double doors had been just seconds prior. The building had simply vanished into thin air.
It's almost like magic, Arthur thought, blinking against the sudden glare of sunlight.
He tightened his grip on Fleur's small hand as they navigated through the bustling tide of pedestrians, horse-drawn carts, and yelling street vendors.
"Fleur?" he asked, leaning down slightly over the noise of the crowd.
"Yes, Brother?"
"Did the building disappear like that every time you visited me?"
"Every single time," she replied, navigating the cobblestone street with familiar ease. "And every time I leave, I end up in a completely different alley or district."
"Then how did you manage to get back to me if you didn't even know where the building was?"
"Well, after I learned your missing persons case was handed over to the Ashen Cell, a Cogguard gave me a strange address that didn't show up on any city map. I was told to send a letter there if I ever needed to reach them. So that's what I did. Every time I wanted to see you, a girl named Melissa would show up to pick me up. She made me wear a heavy blindfold that completely shut off my senses so I could never trace the route."
Arthur shook his head slightly. "They certainly don't take any chances with their security."
They continued their small talk as the crowded marketplace gave way to narrower, quieter residential avenues. Eventually, Fleur led him to a weathered, three-story tenement building with fading paint and creaking wooden balconies.
Is this my house? Arthur wondered, studying the humble structure.
Fleur's face lit up with an eager, radiant smile. She squeezed his hand tightly and tugged him toward the entrance.
"Come on! What are you waiting for?" she urged, practically dragging him up the steps. "Let's get inside before the food gets cold!"
Arthur chuckled and allowed himself to be pulled along. They climbed the narrow wooden stairwell up to the third floor, where the scent of aged wood and distant cooking filled the air. Stopping outside the left-hand apartment, Fleur pulled a brass key from her pocket, slotted it into the worn lock, and turned it with a satisfying click.
The door swung open, revealing their home.
As Arthur expected, the apartment was far from grand. It practically screamed 'hanging on by a thread,' but it was clean and cozy. The layout consisted of just two main areas: a small, functional kitchen and a multipurpose living space.
In the main room sat a wooden bunk bed, a small scholar's desk tucked into the corner, a simple garment rack holding a sparse collection of clothes, and a low dining table set with two mismatched chairs.
Sitting on the table were three plates of food. One held a generous mound of boiled grain smothered in a thick, reddish-spicy broth that gave off a savory steam. Beside it sat a plate of flatbread paired with small, paper-wrapped packets of honey.
To a nobleman or a wealthy merchant, calling this meager spread a "feast" would be a joke. Most people would look at it with pity.
But to Arthur—who had spent an entire past life wandering cold streets, scrounging through trash like a stray dog just to chew on burnt crumbs—this humble meal looked like a feast fit for royalty.
Yet, it wasn't the food that caught his attention first.
He let go of Fleur's hand and stepped toward the corner of the room, stopping right beside the bunk bed. He reached out with trembling fingers and gently poked the mattress, touching it as if it were a sacred artifact.
A bed. An actual bed.
While he had spent the last four days resting in the hospital ward, those iron cots had offered no real comfort. He had felt like an intruder, cautious and tense, knowing it was borrowed time in a place that wasn't his. He couldn't afford to relax.
But this was different. This was home.
Arthur turned to Fleur, a slight, hesitant look in his eyes. "Can I... rest on it?"
Fleur tilted her head, looking at him with a mix of confusion and gentle amusement. "Of course you can, Brother. It's your bed."
Without a second thought, Arthur collapsed onto the mattress, sprawling out flat on his back. A bright, uninhibited grin spread across his face—the first genuine, childlike smile he had worn since his rebirth in this world.
Seeing her older brother act like an excited kid made Fleur burst into a light, melodious giggle.
"We need to eat before you get too comfortable," she scolded gently. "Go wash your hands while I finish setting the table."
She bustled over to the kitchen, grabbing two cracked, lovingly mended porcelain plates. Arthur didn't hesitate. He quickly swapped his stiff outer coat for a soft, worn tunic that was easier to move in, then headed to the basin in the kitchen to wash his hands and face.
When he sat down at the table, Fleur had finished serving. She had sculpted the boiled grain into two neat little mounds on each plate, pouring the spicy red soup over the top so it cascaded down the sides like molten lava.
"Whoa. Ten out of ten for presentation," Arthur teased.
At first, Arthur had been forcing an energetic persona to keep up appearances, but the more time he spent with Fleur, the more natural it felt. The warmth between them felt oddly familiar, as if some long-buried instinct in his soul was recognizing her as his real sister.
Arthur picked up a wooden spoon, scooped up a portion of the grain soaked in spicy broth, and took a bite.
The moment the flavor hit his tongue, he couldn't stop. He ate with ravenous intensity, taking spoon after spoon. It wasn't just hunger driving him; with every mouthful, an overwhelming wave of gratitude washed through his chest. A sudden lump formed in his throat, and he had to fight back the hot tears stinging the corners of his eyes.
"Is it... good?" Fleur asked anxiously, watching him closely. She hadn't even touched her own plate yet.
In truth, the cooking was amateurish. The spices were unevenly mixed, and the soup was a little too thin. But none of that mattered.
"This is the best meal I've ever had in my life," Arthur said softly, looking straight into her eyes. His gaze was tender, filled with a gentle warmth that hadn't been there in a very long time.
A single tear slipped down Fleur's cheek. She tried to brush it away with the back of her hand, but more followed, her emotions finally overflowing.
"Welcome home, Brother," she whispered, her voice thick with emotion.
Arthur simply offered her a soft, reassuring smile.
They finished the rest of their meal in cozy silence. When it came time for dessert, Arthur treated the bread with utmost reverence. He tore open the small paper packet and poured the honey over the golden crust, watching it glisten under the faint room light.
It looked almost like a Golden Piece of Bread
This had been the original Arthur's favorite treat, and it seemed their tastes aligned perfectly. He took a bite, savoring the rich, simple sweetness. It was pure bliss.
Once every crumb was gone, Arthur dragged himself back to the bunk bed and collapsed onto the mattress. His eyelids felt impossibly heavy.
Over by the basin, the soft clatter of dishes signaled that Fleur was already tidying up.
"Fleur..." Arthur mumbled sleepily, his voice fading. "You can leave those... I'll wash them when I wake up..."
"It's alright, Brother," she replied softly from the sink. "You need your rest. Just because you were discharged doesn't mean you're fully healed. Go to sleep. I'll handle everything."
"Thanks..." he murmured. Before he could even finish the thought, darkness pulled him into a deep, dreamless slumber.
When Arthur's eyes fluttered open again, the room was bathed in the dim, golden amber of late afternoon.
He sat up slowly, rubbing the sleep from his eyes and staring at the ceiling. How long was I out?
"Fleur?" he called out, his voice raspy.
No answer.
He swung his legs over the edge of the bed and stood up. The apartment was dead silent—no sound of clattering dishes, no soft footsteps, no humming.
A sudden prickle of anxiety touched his chest. Where did she go? Did something happen?
As he began searching the small apartment, his eyes landed on the scholar's desk in the corner. He hadn't paid much attention to it earlier, but now he noticed it was piled high with parchment, ink wells, hand-drawn maps, and thick hardcovers.
Arthur approached the heavy wooden desk, his fingertips brushing across the dusty spines as he scanned the titles. The collection was dominated by dense historical chronicles and detailed geographical texts, mapping out territorial borders that had likely shifted dozens of times over the centuries. The Original Arthur seemed to have had an obsessive interest in the world's forgotten history.
Tucked between two faded ledgers was a thick volume bound in dark, charcoal leather. Stamped across its spine in faded gold leaf were the words:
The Undercrypt Codex: Arche
The word jumped off the leather like a spark. Arche. It was the exact term Vivienne had dropped back at the facility.
Driven by a sharp, burning curiosity, Arthur slid the heavy book from the shelf. The leather felt cool and weathered beneath his palm. He laid it flat on the desk, the thick parchment pages settling with a soft, dry sigh, and began to read.
THE UNDERCRIPT CODEX
A Foundational Study of Arche, Its Disciplines, and Its Discipline of Practice
Authorized for instruction within the academies of the Dual Council.
PREFACE
What follows is not a record of magic. To call it such is a discourtesy to the generations of practitioners who spent—and surrendered—their lives to prove otherwise.
Arche is knowledge. It is the deliberate, hard-earned comprehension of how a single domain of the physical world behaves beneath its visible surface, coupled with the iron discipline required to act on that understanding through the Undercript—the hidden layer of perception and will that underlies ordinary human sense.
A man who understands fire does not "summon" it. Rather, he understands its fundamental nature so intimately that the fire no longer requires his permission to obey.
This is why Arche cannot be stolen, counterfeited, or bypassed. A practitioner's tier is not an honorary title or a rank to be awarded by decree; it is a precise measurement of how deeply they have grasped their chosen branch of reality. And understanding, unlike coin or noble birth, cannot be inherited.
Read these pages with care. Most of the truths recorded herein were paid for in the blood of scholars who did not survive the learning of them.
ON THE NATURE OF THE UNDERCRIPT
Before a student can begin the study of any specific branch, they must first comprehend the nature of the medium toward which they are reaching.
The Undercript is not a physical place. It is not an external energy reservoir, nor is it a spiritual sense. It is, more accurately, a state of focused cognitive depth—a way of perceiving the world that exists just beneath ordinary macroscopic observation. It is present regardless of whether anyone troubles themselves to look for it, in the same manner that the intricate grain of cedar exists beneath its dark lacquer.
Every domain of the physical world—thermal energy, atmospheric pressure, mass, light, the delicate chemistry of living tissue—possesses a structural reality beneath its visible behavior. The Undercript is a practitioner's capacity to perceive that structure directly and, with sufficient comprehension, to interact with it.
This brings us to the first and most widely misunderstood principle of Arche theory: the Undercript does not grant power; it grants access. What a practitioner achieves with that access is entirely dictated by their understanding of the domain they have unlocked.
A $\text{Tier } 1$ practitioner has merely trained their senses to perceive the underlying structure of their branch.A $\text{Tier } 6$ practitioner, by contrast, has spent a lifetime—sometimes several—learning to act upon that structure with a precision so absolute that, to the untrained eye, it appears as though the laws of nature are being quietly rewritten.
Because of this, no two Archons of the same branch and tier will ever perform identically. The Undercript is a mirror of individual intellect, and no two minds process reality in quite the same way. Two Thermal Archons of equal rank might produce an identical output of heat, yet achieve it through entirely different internal reasoning: one might work through the kinetic agitation of molecular lattices, while another manipulates the thermodynamic logic of combustion. Indeed, a sufficiently advanced scholar can often identify another practitioner's school of thought simply by observing the subtle signatures of their work.
WHAT IS ARCHE?
(Pronounced AR-kay — from the ancient philosophical concept meaning 'the first principle of all things')
Arche is not magic, nor is it a mystical bloodline or supernatural force. It is the capacity of a human mind to consciously perceive and interact with the fundamental laws governing matter. Every atom in the universe obeys strict rules—bonding angles, force interactions, energy states. These rules were not made by man; they were woven into creation at its foundation.
A practitioner of Arche, called an Archai (singular: Archon), does not break those rules. They understand them deeply enough to direct them with intention. A bird does not violate the sky by flying; an Archon does not violate creation by understanding it. The latent ability to perceive this underlying layer—the Undercript—exists naturally in a small percentage of the population.
The Core Law: Knowledge Is the Gate
An Archon can only interact with what they truly comprehend.
This does not mean an approximate or superficial awareness. It requires absolute, mathematical comprehension down to the microscopic scale demanded by one's current tier. A person who merely knows that "fire is hot and burns wood" cannot command combustion. But an Archon who understands the precise bond dissociation energies of the fuel, the radical chain reaction mechanisms of ignition, and the thermodynamic equations governing the flame—that mind is dangerous.
Mind Over Might: A scholar with modest raw potential but a brilliant intellect can achieve extraordinary, elegant feats.The Danger of Ignorance: A powerful but uneducated Archon is a hazard, limited to blunt, wasteful, and volatile outbursts.The Compound Effect: Knowledge is cumulative. Every new principle mastered unlocks the threshold to adjacent physical laws.Personalized Mastery: Your history, your studies, and the unique trajectory of your life will define the ultimate shape of your power.THE MECHANICS OF ARCHE: THE PRINCIPLE OF RESONANCE
To understand how Arche bridges the gap between human intent and physical matter, we must observe three fundamental realities:
Reality is Made of Vectors: At the atomic level, everything physical is a structural dance of forces. When hydrogen and oxygen share electrons to form a molecule of $\text{H}_2\text{O}$, they are bound by electromagnetic vectors. These invisible forces are the actual gears of the physical cosmos.The Human Limitation: Under normal circumstances, humans can only manipulate matter at the macroscopic level. Our hands are too clumsy, our physical actions too blunt to touch the tiny machinery of atoms.The Resonant Bridge: Every atom is constantly broadcasting its state—its electrons shifting, its chemical bonds vibrating. Through Arche, an Archon's mind acts as a cognitive transmitter, broadcasting a signal on that exact microscopic frequency. It is the principle of sympathetic resonance: if you strike a tuning fork, an identical fork across the room will begin to hum in unison without ever being touched.
Arche provides the transmitter; your accumulated knowledge provides the correct frequency. Without both, there is only silence.
Therefore, every act of Arche requires three synchronized steps:
Perception: Tuning your awareness to hear the Undercript.Translation: Converting your intellectual understanding of a physical law into a precise cognitive broadcast.Interaction: The physical matter receiving that broadcast and rewriting its behavior to match your signal.
Arthur was so deeply absorbed in the text that the sudden, sharp scrape of the door latch sounded like a thunderclap in the quiet room.
He flinched, his heart leaping into his throat. His fingers reacted faster than his thoughts, slamming the heavy leather-bound book shut with a dull, echoing thud. Spinning in his seat, his hand dropping instinctively to the edge of the wooden table, he stared with wide, intent eyes at the opening doorway.
