Two days had passed since Ambassador Petrov's hurried departure, and the castle of Border Town had undergone a metamorphosis. The great dining hall, once a place for cold meals and hushed, fearful conversations among servants, had become the setting for a scene unprecedented in the history of Graycastle. Roland had realized early on that for his industrial revolution to take root and prosper, knowledge could not be a hoard he kept locked inside his own mind. It had to be shared, cultivated, and weaponized.
However, with the presence of Arthur and William, the overwhelming burden of teaching "Natural Sciences" was now divided. The hall was no longer a room for banquets; it was a three-pronged improvised laboratory, a temple of reason where the laws of the old world were being systematically dismantled. The air was thick with the scent of fresh ink, the scratch of quills on rough parchment, and the occasional sharp smell of ozone whenever magic flickered in the corner.
Roland and Anna: The Essence of Matter
In the brightest corner of the hall, near the large hearth, Roland pored over thick stacks of parchment with Anna. He focused on the foundational concepts of chemistry and advanced physics. On the table between them, Roland had drawn a series of diagrams that would have looked like occult symbols to any priest: circles representing atoms, connected by lines of force.
— "Anna, you must understand that the green fire you create isn't just a mystical 'gift' or a random burst of heat," Roland explained, his voice low and patient. He tapped a drawing of a molecular structure. — "It is a reaction. Everything in this world—the air we breathe, the iron in your forge, the water in the river—is made of tiny, invisible particles called atoms. They are constantly in motion."
Anna observed the drawings with her usual logical seriousness. She didn't blink, her blue eyes absorbing every line and curve as if they were the only absolute truths she had ever encountered. To her, Roland's science wasn't just homework; it was the holy language that finally explained her very existence, stripping away the Church's labels of "sin" and "demon."
— "If we can understand how these particles move and how to agitate them," Roland continued, his eyes bright with excitement, "your fire can reach temperatures that no ordinary coal furnace could ever dream of achieving. We won't just melt iron, Anna. We will purify it. We will create steel so strong it will change the face of the world."
Anna reached out, her finger hovering over a diagram of an oxygen molecule. — "So... I am not creating something from nothing. I am simply changing the speed of what is already there?"
Roland smiled, a genuine sense of pride swelling in his chest. — "Exactly. You aren't a witch of destruction, Anna. You are a master of kinetic energy."
Arthur and Nana: The Biology of Healing
At a smaller table nearby, Arthur had taken on the delicate responsibility of teaching little Nana Pine. He realized that a child's mind couldn't jump straight into cellular biology, so he translated complex concepts of regenerative medicine into metaphors she could grasp.
— "Nana, I want you to think of your power not as a scary divine miracle, but as an army of tiny, invisible workers," Arthur said, his voice soft and encouraging. He sketched a simple cell structure on a piece of paper, drawing little men with hammers and bricks inside a circle. — "When you heal a bird's wing or a soldier's cut, you aren't just 'wishing' the pain away. You are giving the body the right building blocks so it can rebuild itself faster. You are the architect, and your magic is the supply wagon."
Nana listened, her head tilted to one side. The initial, paralyzing fear she had felt toward her own magic was slowly beginning to thaw. As she realized there was a logic—a set of rules—behind the glowing, semi-liquid substance that emanated from her hands, she felt a sense of control she had never known.
Arthur, however, remained subtly anxious. His eyes occasionally flickered toward the empty spaces of the room, the shadowed corners where the light of the candles failed to reach. He knew that Nightingale was likely watching this very lesson from the silence of the Mist World. He made a conscious effort to ensure his "science" was presented as something purely beneficial, a tool for life and preservation, hoping the invisible assassin would see the sincerity in his eyes. He wasn't just teaching a girl; he was performing a silent plea for an alliance.
William and Carter: The Physics of Combat
In the center of the room, the atmosphere was far more kinetic. William had brought Commander Carter Lannis into the fray. He had decided that the best way to gain the knight's respect was to teach "applied physics" through the only language Carter understood: combat.
— "Tell me, Carter, do you honestly believe your sword cuts through a leather gambeson only because of the raw strength in your bicep?" William asked, performing a lightning-fast shadow-boxing maneuver that left the knight blinking. — "It's not just muscle, my friend. It's about inertia and acceleration. It's about the vector of impact."
Carter arched an eyebrow, his hand resting habitually on the pommel of his longsword. He looked skeptical, clearly struggling to reconcile this "scholar" talk with the bloody reality of the battlefield. But William's display of martial arts—the efficiency of his footwork and the way he shifted his weight—forced the veteran knight to pay attention.
— "The Prince is creating weapons that use the rapid expansion of gas to propel lead, Carter," William continued, ignoring the knight's lingering disbelief. He grabbed a heavy metal paperweight and mimicked the trajectory of a bullet. — "The era of the knight in shining steel armor is coming to a close. It doesn't matter how thick your breastplate is if a projectile is moving at a thousand feet per second. In the new world, what matters is pressure, velocity, and the discipline to hold a line."
Carter frowned, looking at the drawings of the first "flintlock" prototypes Roland had been sketching. — "A world without the honor of the blade? That sounds like a cold place, William."
— "It's a practical place," William countered with a grin. — "And I'm going to make sure you're the one holding the faster weapon."
The afternoon continued in a low hum of intellectual labor—the sound of quills scratching urgently against paper and the occasional heated debate over a mathematical formula. William, true to his boisterous style, tried to crack jokes to lighten the heavy atmosphere, while Arthur would occasionally stand up to discreetly point out a decimal error in Roland's bridge-load calculations.
During a rare moment of silence, as the four of them paused to drink some water, Anna looked up from her atom diagrams. She looked at Roland, then at Arthur and William, her expression one of profound, frank curiosity.
— "The three of you," she said, her voice cutting through the room with its characteristic bluntness. "You speak of the future—of these 'engines' and 'vectors'—as if it is already written somewhere. As if you are merely reading a book that the rest of us cannot see."
Arthur and William exchanged a long, knowing look. In that silent second, the weight of their secret felt heavier than the castle walls. They knew that in this world of mud, superstition, and Church-sanctioned ignorance, they were the architects of a script that no pope or king could ever have foreseen.
— "We aren't reading the book, Anna," Arthur finally said, a small, sad smile playing on his lips. — "We're just the ones who remember how it's supposed to end. And we're making sure this time, the ending is a good one."
Anna nodded slowly, accepting the answer for now. As the sun dipped below the horizon, casting the hall in a deep, orange glow, the union of Anna's fire, Nana's healing, and Carter's discipline—all guided by the "alien" science of the three men—felt like the true foundation of something indestructible. The winter was coming, and the beasts were hungry, but in this room, the future was being forged in the white-hot heat of knowledge.
