The chamber of House Bun was warm.
Not comforting warmth—controlled warmth. Braziers burned evenly along the stone walls, their flames steady, unbothered by drafts. The long table at the center of the hall reflected their light dully, polished so often it had lost the ability to shine.
At its head sat the lord of the house.
He did not speak.
His presence was indicated only by the slow, rhythmic tapping of a finger against the armrest of his chair.
Tap.
Tap.
Tap.
The vice-captain of the guards stood rigidly at the center of the chamber, helmet tucked beneath his arm. To his right stood Jos, head of the miners' guild under House Bun—broad-shouldered, soot still ingrained beneath his fingernails no matter how often he scrubbed.
Neither man dared to speak until acknowledged.
The tapping stopped.
"Repeat it," the lord said.
The vice-captain swallowed. "At dawn three days ago, my lord, patrols discovered unauthorized entry into the Western Far Mines. There were no alarms triggered, no dead guards, and no signs of forced entry at the main shafts."
Jos clenched his jaw. "But the ore was gone."
"How much?" the lord asked.
Jos hesitated. "Enough to halt operations for weeks. Refined veins. Mana-laced stone. Extracted cleanly."
The lord leaned back slightly.
"No carts," he said. "No caravans."
"No tracks," the vice-captain replied. "That's the strangest part. Whatever carried it didn't use horses."
Tap.
Tap.
Tap.
"Witnesses?"
"One,"Jos said, "A perimeter sentry. He described a… vehicle."
The tapping slowed.
"A vehicle," the lord repeated.
"Yes, my lord. Large. Armored. Moved without beasts. Engine noise was… muted."
The lord was silent for a long moment.
"And the attackers?"
"Clad in black," Jos said. "Head to toe. Even the face."
Tap.
The lord's finger paused.
"Even the face?"
"Yes."
The lord's voice lowered. " that leaves only one profession capable of this" he said, "an outlaw engineer."
The question hung in the air.
Jos shifted uneasily. "If so, my lord… this is beyond banditry."
"Captain Rell?" the lord asked.
The vice captain's throat tightened. "Missing."
"No body?"
"No blood."
The vice-captain added quietly, "His trail ends abruptly. As if he was… removed."
Silence settled over the chamber.
The lord rose from his chair.
Only then did both men bow deeply, eyes fixed on the stone floor.
"This is not to be spoken of outside this room," the lord said calmly. "No guild reports. No petitions. No accusations."
"My lord—" Jos began.
"If this is an engineer," the lord continued, "then attention is what he wants least. And what we cannot afford to give."
He turned away.
"Double patrols. Quietly. And find out where that ore went."
"Yes, my lord."
As they were dismissed, the lord's finger resumed tapping.
Tap.
Tap.
Tap.
Deep beneath the earth, the cave did not care.
The control room hummed with life.
Light panels floated around Seth in layered arrays, translucent blue and white interfaces folding and unfolding as data flowed. Mechanical arms mounted along the ceiling moved in precise arcs, assembling components at impossible speeds.
Metal skeletons took shape on one platform.
On another, crystalline processors were etched with microscopic runes by laser-guided tools.
Seth stood at the center of it all, still as a statue, eyes unfocused yet attentive.
"Begin integration sequence," he said.
CONFIRMED.
Cables descended from above, connecting directly into his primary system core. Streams of code scrolled across the nearest display—not magical, not divine, but structured logic refined beyond conventional engineering.
This was not a mind.
Not yet.
"This upgrade is long overdue," Seth muttered.
The dungeon had grown too complex. Too layered. Too dependent on his constant oversight. Reaction times lagged by fractions of a second—imperceptible to others, unacceptable to him.
He needed delegation.
But not autonomy.
"Framework stability?" he asked.
EVALUATING… STABLE.
Seth adjusted parameters manually, rewriting behavioral constraints as machinery continued its work around him.
The AI architecture was modular, segmented into layers: perception, prediction, execution. No emotional modeling. No self-preservation protocols.
Aid would not want.
It would optimize.
"Begin synthesis."
The system paused.
WARNING:
ADVANCED INTEGRATION MAY RESULT IN EMERGENT BEHAVIOR.
Seth's expression didn't change.
"Proceed."
The core pulsed.
Light flared briefly, then stabilized.
For a moment, nothing happened.
Then—
SYSTEM ONLINE.
The room seemed… quieter.
Not silent. Just more focused.
Seth exhaled slowly.
"Designation," he said. "You will be called Aid."
ACKNOWLEDGED. DESIGNATION SET: AID.
"Report."
DOMAIN STATUS: STABLE.
RESOURCE DISTRIBUTION: OPTIMAL.
SECURITY INTEGRITY: NORMAL.
Seth nodded once.
"Fourth floor."
FOURTH FLOOR: UNDER CONSTRUCTION.
STRUCTURAL FRAMEWORK COMPLETE: 41%.
AWAITING DIRECTIVE FOR FUNCTIONAL DESIGNATION.
Seth was about to respond when the door slid open.
Footsteps echoed softly.
Evelyn entered first.
She held a transparent plastic box against her chest with both arms, fingers gripping it too tightly. Her steps were hesitant, measured, as though afraid to disturb the room itself.
Agatha followed behind her, expression unreadable.
Evelyn stopped a few steps away from Seth.
Evelyn stopped a few steps in front of Seth.
She hesitated—just long enough for him to notice.
"Boss," she said softly, stepping closer. "This… this is for you."
She extended the transparent plastic box in her hands. Her grip was tight, knuckles faintly pale, as if she were afraid it might slip—or be rejected.
Seth turned his head toward her voice.
"For me?" he asked.
Agatha, lounging a few meters back with her arms crossed, smiled faintly. "It's a present," she said. "I'd love to see your reaction."
Seth reached out and took the box. It was light. Too light for anything mechanical. He placed it on his lap and carefully opened it, withdrawing what lay inside.
The moment his fingers brushed the surface, he paused.
No energy signature.
No mana fluctuation.
No heat, no vibration, no sound.
Just… texture.
He ran his fingers slowly across the material, feeling the weave, the stretch, the smooth inner lining.
"…This feels nice," Seth said honestly.
Agatha's smile widened. "It's a bodysuit."
Evelyn nodded quickly. "Lady Agatha came up with the idea. She said you'd love it."
Seth tilted his head slightly toward Agatha.
"Oh really."
Agatha lifted one shoulder in a casual shrug. "You're into things like this. Functional. Close-fitting. Something you can actually move in. Maybe you'll use it on your next patrol."
A quiet huff of amusement escaped him. "Nice one, Agatha."
Evelyn visibly relaxed.
Seth continued examining the suit with deliberate care. The stitching was clean. Reinforced in key areas. Whoever made it had paid attention—not just to form, but to movement.
After a few moments, something clicked.
An idea surfaced.
"Evelyn," Seth said, turning toward her, "I was planning on making a new bodysuit anyway."
Her eyes widened.
"…You were?"
"Yes. A stronger one. More durable." He paused. "How about you join me in the workshop in two… maybe three hours?"
She blinked, then smiled. "You think so?"
"I'll gladly assist you, boss."
Seth nodded. "Good. Go get yourself prepared. This build will take several hours."
"Sure thing!"
She turned quickly and left the control room, footsteps light, almost skipping.
Agatha watched her go.
"Look at her," she murmured. "So eager."
Seth sighed. "What are you up to?"
Agatha leaned forward. "I should be asking you that. I never thought you'd want to make a suit."
"That's because I never had the time," he replied. "Not one worth wearing."
Agatha arched an eyebrow. "You're not going to throw what she made into the dirt, are you?"
"No," Seth said flatly. "I'm not as heartless as you."
She laughed softly. "Look who's talking. Hours ago you sacrificed—"
"I don't want to hear it."
Silence stretched for a beat.
"I was going to remodel it," Seth added. "Improve it."
Agatha smirked. "Maybe you're sweeter than you think."
"Leave me alone and go your way."
She leaned against the back of his chair. "You're no fun."
Seth stood.
He draped the suit over his shoulder—and from within his jacket withdrew a cube.
It pulsed.
Slow. Rhythmic.
Thump.
Thump.
Agatha's eyes dropped instantly. "What is that?"
"I don't know," Seth said. "Some kind of creature's heart."
Her gaze sharpened. "Where did you get it?"
"From the mine, obviously." He turned toward the laboratory doors. "And I'm about to find out what it is."
She followed.
The laboratory was colder than the control room. Sterile. White panels, segmented workstations, suspended mechanical arms resting in dormant positions.
Seth crossed to the leftmost corner and placed the cube inside a transparent iron-glass containment vessel. Two thick pipes fed into the chamber from behind.
"Barrier," he said.
Agatha hesitated.
Then she raised her staff and cast a layered spell, sealing the vessel in shimmering translucence.
Seth sat at the edge of a chair, fingers steepled.
"Never seen a grey beating cube before," Agatha muttered.
Seth frowned slightly. "…So it's grey."
He activated the scanners.
Beams of structured light passed over the cube. Rays, pulses, resonance checks—all coordinated through Aid.
SCANNING…
MATERIAL CLASSIFICATION: UNKNOWN
ENERGY SIGNATURE: ADAPTIVE—UNSTABLE
Agatha attempted an appraisal.
Nothing.
She stepped back, arms crossed, watching.
Seth introduced variables.
First, stone.
Then mana-laced ore.
Crystals.
Raw chunks from the Western Far Mines.
Thirty minutes passed.
The cube twitched.
Its pulse shifted.
Agatha leaned forward. "…Seth. It's changing color."
He stiffened. "To what?"
"…To match them."
The cube's surface darkened, faint veins of color crawling across it—mirroring the materials inside the chamber.
Seth focused.
Then—
THUMP. THUMP.
The beating doubled.
The cube surged forward, vibrating violently, drilling against the iron-glass.
Cracks spiderwebbed outward.
Agatha raised her staff instantly.
"Harden the barrier," Seth said calmly.
She did.
"Aid," he continued, "drop internal temperature."
The chamber frosted over.
Ice formed.
The cube slowed—but did not stop.
"Freeze it," Seth said. "Direct ice beams."
Streams of concentrated cold slammed into the cube. Steam hissed. Frost thickened.
The beating slowed.
Then stopped.
Seth approached.
"Full scan," he ordered.
SCANNING…
RESULT: NORMAL PARAMETERS
Minutes passed.
Then—
ALERT: ENERGY IMITATION DETECTED
Cold surged outward.
Frost crawled across the cube's surface.
Agatha's eyes widened. "It's… absorbing it."
The cube coated itself fully in ice.
Then—
THUMP.
It beat again.
Twice as fast.
Seth's lips parted slightly. "…Could it be—"
Thirty minutes later, the cube stopped.
Then surged again—slamming the glass harder than before.
Ice shattered.
"Flamethrowers," Seth ordered.
Fire roared.
Heat spiked.
The chamber glowed.
Ice melted into steam. Metal warped.
Slowly… the cube stilled.
Its surface burned.
Lines ignited.
Then—
Heat radiated outward.
Magma-like flames engulfed it.
The beating intensified.
The barrier cracked.
"Aid—warnings?" Seth asked.
MULTIPLE ABNORMALITIES DETECTED
CONTAINMENT FAILURE IMMINENT
The iron-glass melted.
The cube shot forward—
Agatha raised her staff—
Too slow.
Seth moved.
He wrapped the bodysuit around the cube with both hands.
"Electromagnetic sequence," he commanded.
Power surged.
A ring-shaped apparatus rose from the floor, neon blue lightning snapping across its arc.
Seth threw the wrapped cube into it.
Electricity struck.
The cube screamed—soundless.
The beating slowed.
Energy drained.
Agatha slammed barriers into place.
Seth lowered his hands, palm burning.
"Did it get you?" she asked sharply.
"You don't have to worry."
She stared at the cube. "That thing adapts. I object to taking this further."
Seth flexed his fingers.
"A mystery," he said quietly.
Then he smiled.
"That adapts."
The laboratory did not return to normal.
Even after the barriers stabilized.
Even after the alarms fell silent.
Even after the cube's violent beating slowed into something almost… patient.
Seth stood a few paces from the containment ring, arms lowered, fingers still tingling faintly from residual heat. The bodysuit—Evelyn's suit—was wrapped around the cube, caught midair by the electromagnetic field, pinned in place by arcs of controlled lightning that crawled across its surface like living veins.
The cube beat.
Slow.
Steady.
Not frantic anymore.
Agatha remained beside him, staff grounded, eyes never leaving the object. "It stopped trying to escape," she said quietly.
"Yes," Seth replied. "That's what concerns me."
Aid's processing arrays hummed softly overhead.
CONTAINMENT STATUS: STABLE.
ENERGY OUTPUT: REGULATED.
ADAPTIVE RESPONSE: ACTIVE.
Agatha tilted her head slightly. "Define active."
A brief pause.
ENTITY IS NO LONGER RESPONDING TO THREATS.
CURRENT BEHAVIOR INDICATES ENVIRONMENTAL ANALYSIS.
"…Analysis?"
Agatha brow furrowed. "Explain."
ENTITY RESPONSE MODEL UPDATED.
DAMAGE-AVOIDANCE PRIORITY: LOW.
CONDITIONAL LEARNING PRIORITY: HIGH.
The words settled slowly.
Seth replayed the sequence in his mind—not emotionally, but structurally. Cold. Heat. Pressure. Electricity. Each time the cube had not resisted blindly. It had waited, adapted, then responded with precision.
Not panic.
Not instinct.
"Passive," Seth murmured.
Agatha looked at him sharply. "What?"
"It's not defending itself," he said. "It never was."
Aid continued, unprompted.
ENTITY DOES NOT ATTACK HOSTILE INPUTS.
ENTITY ADAPTS TO CONDITIONS TO MAINTAIN FUNCTIONAL CONTINUITY.
Agatha felt a chill creep up her spine. "Seth… that thing isn't alive the way we understand life."
He didn't answer immediately.
Instead, he stepped closer to the containment ring.
The bodysuit was scorched in places, fibers darkened, seams strained—but it had not torn. The material Evelyn had stitched by hand had endured temperatures that warped metal and energies that defied classification.
And now—
Now it was changing.
Seth extended two fingers and brushed the outer surface of the suit where it pressed against the cube.
Something responded.
Not violently.
Not eagerly.
The cube's surface shifted beneath the fabric, subtle lines forming, aligning—mirroring the internal weave of the suit itself. The lightning crawling across the ring faltered for half a second before stabilizing again.
Aid's tone sharpened.
WARNING.
MATERIAL INTERACTION DETECTED.
Agatha took a step forward. "Seth—"
"I see it," he said.
The suit's internal structure was no longer uniform. Certain fibers had stiffened. Others had softened, becoming unnaturally receptive—almost receptive on purpose.
"Run a structural balance analysis," Seth ordered.
ANALYZING…
The pause stretched longer than before.
RESULT: IMBALANCE CONFIRMED.
MATERIAL INTEGRITY: COMPROMISED.
ADAPTIVE INFILTRATION DETECTED AT 17%.
Agatha exhaled slowly. "It fused?"
"Yes."
The cube had not merely been restrained by the suit.
It had entered it.
Not by force.
By compatibility.
Seth's jaw tightened.
"Is the cube still contained?" she asked.
AFFIRMATIVE.
HOWEVER—
CURRENT CONFIGURATION CREATES FEEDBACK LOOP BETWEEN ENTITY AND MATERIAL.
Agatha turned to him fully now. "Meaning?"
"Meaning," Seth said quietly, "the suit is no longer neutral."
The cube beat again.
Once.
The suit responded—its fibers subtly flexing in rhythm, as if echoing the pulse.
Seth withdrew his hand.
"That thing learned," Agatha said, "intellectual?"
"Yes."
"From you?"
"No." Seth shook his head once. "From the environment."
He straightened.
"From my systems."
A silence followed—thick, heavy, dangerous in its implications.
Agatha broke it first. "Then destroy it."
Seth did not reply immediately.
Instead, he turned and reached out, deactivating the electromagnetic ring. The lightning died down. The suit and cube dropped gently into his waiting hands.
Agatha stiffened. "Seth."
"It's stable," he said. "For now."
"And if it isn't?"
"Then it won't get a second chance."
He examined the suit more carefully now, fingers tracing the altered sections. The adaptive integration was uneven—stronger along the spine, weaker at the joints. Left uncorrected, it would fail catastrophically under stress.
Imbalance.
Flawed evolution.
Aid spoke again.
RECOMMENDATION:
DISASSEMBLE AND ISOLATE ADAPTIVE MATERIAL.
Seth considered it.
Then shook his head.
"No."
Agatha stared. "You're keeping it?"
"I'm correcting it."
"That thing nearly killed you."
"And it didn't," he replied calmly. "Because this stopped it."
He lifted the suit slightly.
"This was made by elf hands," Seth continued. "With intention. With limits."
He paused.
"And it learned something it shouldn't have."
Agatha understood then. "You're going to reforge it."
"Yes."
"Personally?"
"Yes."
Aid processed.
MANUAL REFORGING INCREASES RISK.
Seth's expression hardened. "And reduces unknown variables."
He turned toward the forge chamber.
"This suit cannot remain as it is," he said. "If it exists, it will either become a liability—or a boundary."
Agatha followed a step behind. "And the cube?"
Seth did not slow.
"The cube doesn't understand purpose," he said. "Only conditions."
He entered the forge chamber and placed the suit on the central platform.
"So I'll teach it one."
The machinery powered on.
Heat rose.
A metallic blindfold locked into place around his head.
Tools aligned.
Deep beneath the earth, as systems prepared to reshape matter and intention alike, something waited—quiet, adaptive, learning not what Seth was…
…but how he chose to correct his mistakes.
And that, perhaps, was the most dangerous lesson of all.
