The breakfast room of the Grant Estate was unusually quiet that morning. Sunlight streamed in through the tall windows, falling in sharp rectangles across the polished oak floor. Silver utensils glimmered in the light, and the faint aroma of baked bread mingled with the soft hiss of tea steam. Lucas sat at the head of the long table, crimson eyes scanning a diplomatic report. Every so often, his fingers twitched toward the quill as if the paper itself might stray from perfect order.
Across from him, Dwayne crouched over the toaster, small fingers probing the coil with surgical precision. "Father," he said, blue eyes narrowed, "if the coil is wound at 0.2 millimeter intervals rather than the optimal 0.19, you are losing approximately 0.7% of thermal efficiency per cycle. This is inefficient."
Lucas exhaled slowly, pinching the bridge of his nose. "…Dwayne, it is breakfast. Not a laboratory."
"The two are equivalent if we define efficiency as output per input," Dwayne replied, straightening and inspecting the lever. "We could improve—"
Before Lucas could stop him, a servant arrived carrying a scroll unlike any he had ever seen. Heavy. Copper-bound. The surface etched with precise diagrams and runes rather than ink, the scroll radiated the weight of ancient engineering knowledge. It pressed against the small table as if challenging the room itself.
Lucas lifted it carefully, noting the sheer density of the metal. "…Dwayne," he said cautiously, "…the Dwarf King is… abrasive. He values machines over people. You—" He glanced at the child, "value people too much, I hope?"
Dwayne cocked his head, expression blank but calculating. "Father, I also value machines over most people. The variables are more consistent. This appears to be a highly compatible diplomatic mission."
Lucas exhaled in frustration, realizing he would have to pack Dwayne's soft socks—the thick, warm ones his son refused to wear for style. The Iron Mountains were unforgiving, and the child deserved comfort, even if Lucas's pride refused to admit it.
Dwayne, meanwhile, traced the etched diagrams with one tiny finger. "These etchings display a paradoxical sequence," he said, voice calm and measured. "It is a challenge designed for an individual capable of recognizing iterative feedback loops within mechanical systems. This is… intriguing."
Lucas rubbed his temple. "…Yes, it is intriguing, Dwayne. And dangerous. We leave at dawn."

The carriage that carried them west rumbled along, wheels rattling over cobblestones, the Orbia plains fading into jagged peaks. Prince Edgar sat across from Dwayne, attempting royal composure, though his pale face betrayed his growing nausea.
"I think I am going to—" Edgar muttered, clutching the armrest.
"Focus on the horizon," Lucas said sharply. "Stop moving your diaphragm in that… panicked pattern."
"…Thank you, Father?" Edgar asked weakly, eyes wide.
Elton Ren, sword in hand, sat silently, sharpening his practice blade with precise, slow strokes. Every shadow along the cliffs drew his attention, and his posture remained tense, ready for any threat.
Dwayne ignored the scenery completely, murmuring about wheel-rotation-to-friction ratios and calculating the energy loss of the carriage's suspension system. Lili Hughes, finally giving up on reading, leaned against the door, arms crossed.
"You're missing the scenery!" she said, frustrated.
"It is statistically irrelevant," Dwayne replied. "Unless you are gathering qualitative data on biome distribution for a lateral study in ecosystem efficiency."
The Iron Mountains rose sharply, smoke curling from volcanic vents, sulfur thick in the air. The green Orbia plains had faded entirely, replaced by jagged cliffs and black stone. To most eyes, the mountains were foreboding. To Dwayne, they were a set of variables to be analyzed.

The entrance to Demgon was immense. A massive stone door dominated the valley, its surface engraved with interlocking gears, arcs, and channels powered by a roaring waterfall. The water's rush filled the air, while the metallic rhythm of the gears—thrum-thrum-thrum—vibrated through the stone underfoot like the heartbeat of the mountains themselves.
General Brock, a dwarf in polished steel and bronze, stepped forward, voice gruff and suspicious. "We asked for a genius," he grumbled, "not a porcelain doll in a silver coat."
Dwayne approached, small but unflinching. His gaze locked on a loose gear near the bottom of the massive door. He crouched and tapped it lightly with the tip of his boot.
"Your hydraulic pressure is leaking at a rate of three liters per hour," he said, calm as ever. "The seal is four millimeters too wide. It is loud and embarrassing."
Brock froze. "…You—you dare insult the gate?"
"…I am not insulting," Dwayne replied, hands behind his back. "I am correcting a mechanical inefficiency. Observe the difference between intended output and actual performance."
"You're four years old!" Brock shouted. "Four!"
"…Chronological age is irrelevant to variable analysis," Dwayne said, voice steady.
Lucas stepped forward, hand resting lightly on his sword. "He is my ward. You will treat him as such—or I will treat you as an inefficient obstacle."
The dwarves exchanged stunned glances. None had ever been addressed so bluntly, particularly regarding a machine built with centuries of pride. Brock's jaw hung slightly open, disbelief etched across his face. Even the younger dwarves, apprentices and engineers alike, muttered among themselves, impressed by the child's confidence and insight.

King Thrum's chamber was vast, suffused with the scents of heated metal and mana-infused oils. At the center rested the legendary "Infinite Cube." Its surface was a maze of interlocking gears, conduits, and arcane circuitry. The machine had powered the Great Forge for over a millennium, and yet now it sat motionless, silent, a puzzle centuries in the making.
"…If you fail," King Thrum rumbled, his voice echoing through the stone hall, "you will remain as apprentice for ten years. Orbia will not receive its trade deal. Understand?"
Dwayne approached, his small figure oddly commanding amidst the massive dwarves. He observed the Cube with unblinking intensity, noting every gear, every conduit, every minuscule disruption in the mana flow. The dwarves gathered around, muttering, tapping their hammers as if brute force could remedy the centuries-old puzzle. None dared attempt more.
Dwayne entered his "blueprint state." In his mind, the world shifted into a grand diagram of moving light. Gears rotated in invisible lines; mana flowed in threads of radiant energy; the single piece of grit lodged in the conduit stood out as an irregularity that disrupted the system.
Without hesitation, he withdrew his silver mana-pen. Its tip threaded delicately into the conduit, nudging the grit free with precise movements. He didn't pound, he didn't force; he adjusted.
The Cube began to spin. Smoothly. Perfectly. The hum of the gears became harmonious, each rotation in alignment.
Dwayne straightened, hands clasped behind his back. "A machine is only as strong as its smallest variable. This is a metaphor for your kingdom, King Thrum. You are neglecting the small gears."
The dwarves were stunned into silence. Then, King Thrum laughed, a deep, rolling sound that reverberated through the chamber. "…Hah! Well said, human child. Orbia shall have its trade deal, and you… are welcome in Demgon anytime."
The dwarves bowed, some reluctantly, some with newfound respect. Even General Brock, who had scoffed earlier, gave a subtle nod of approval.

As the dwarves celebrated, Dwayne requested distilled water and began analyzing the airflow and energy efficiency of the forge fires. Lucas, standing quietly in the shadows, hand on the hilt of his sword, observed him. He watched his tiny son navigate the room of proud, stubborn dwarves with nothing but intellect and composure.
A pang of emotion hit him—a flicker of pride he immediately masked with a scowl. The warmth remained, hidden under layers of cold resolve.
Then the chamber doors opened. A messenger, pale and breathless, appeared, clutching a scroll sealed in green wax. "The Great Tree is dying," he said urgently. "…We need the Boy of Equations."
Lucas's red eyes narrowed to narrow slits. Dwayne, calm as always, glanced up. "Another variable," he said simply. "Interesting."
The rhythm of the forge, the gears of the Iron Mountain, and the hum of ancient machinery seemed to echo Dwayne's words. Somewhere deep within the mountains, the first gears of the next conflict began to turn.
