The Andrea estate had stood for centuries without surprise.
Its walls were old stone, not merely for defense but for memory. Every crack had been earned through weather, war, or time. The banners hanging from its towers stirred lazily in the afternoon wind, crimson and gold catching the light as they always had. Servants moved through courtyards in practiced routes. Knights drilled in the outer yard. Scribes bent over parchment within shaded halls.
Routine ruled the estate.
That was why the arrival of the scout squad drew attention long before they passed through the gates.
Six riders entered the outer grounds in tight formation, armor dulled by travel rather than battle, cloaks stained with mud and pine resin. Their horses were lathered and restless, nostrils flaring as if they had outrun something they could not leave behind. The guards at the gate noted the way none of the riders spoke, how their captain raised a fist sharply rather than offering casual greeting.
They rode straight for the keep.
Sir Haldren dismounted first.
He was a veteran by any measure—broad-shouldered, greying at the temples, his breastplate marked with old repairs rather than decoration. He did not remove his helm until he reached the marble steps of the audience hall. When he did, the lines in his face seemed deeper than when he had left days earlier.
A steward approached, already bowing.
“Captain Haldren. His Lordship is in council.”
Haldren nodded once. “Then he’ll want this council adjourned.”
That alone ensured the doors opened.
Lord Andrea sat at the head of the long oak table, fingers steepled as he listened to a trade dispute between two minor bannermen. He was a man whose presence carried authority without force—silver-haired, sharp-eyed, dressed simply for a noble of his rank. When the chamberlain leaned close and murmured in his ear, Andrea’s gaze flicked toward the doors.
He raised one hand.
“That will be all,” he said calmly. “We will resume tomorrow.”
The bannermen bowed, relief and irritation warring in their expressions. They filed out, murmuring softly among themselves.
When the doors closed again, Lord Andrea leaned back in his chair.
“Captain Haldren,” he said. “You returned sooner than expected.”
Haldren dropped to one knee, fist to chest.
“My lord.”
“Rise. And speak.”
The captain stood. His men remained near the doors, silent, eyes fixed ahead.
“We were dispatched to investigate the disturbances reported at the eastern border,” Haldren began. His voice was steady, but there was an edge beneath it, like steel pressed too tightly into its sheath. “Unusual wildlife movement. Reports of soundless tremors. Disappearances of game.”
Andrea nodded. “And?”
“We found a structure, my lord.”
Andrea’s fingers paused.
“What kind of structure?”
Haldren took a breath. “A cathedral.”
Silence followed.
Andrea blinked once. “A… cathedral.”
“Yes, my lord.”
The word felt wrong in the chamber, like a foreign coin laid upon familiar wood.
“At the border?” Andrea asked.
“Precisely at the borderline,” Haldren said. “Where the grasslands thin and the forest begins. Black stone. Massive. Its foundations rest directly on open earth—no surrounding settlement, no road, no markers of ownership or construction.”
Andrea’s gaze sharpened. “That land was clear the last time it was surveyed.”
“Yes, my lord. I personally led patrols through that region less than a season ago.” Haldren’s jaw tightened. “It was not there.”
Andrea leaned forward slightly. “Describe it.”
Haldren gestured subtly, and one of the scouts stepped forward, placing a rolled charcoal sketch onto the table. Andrea unrolled it slowly.
The drawing was rough but unmistakable.
A towering black cathedral rose from open grass, its spires jagged rather than elegant, its walls unadorned by iconography. The forest behind it loomed like a wall of dark teeth. No windows were visible from the front—only vast stone surfaces and a single archway large enough to admit a siege engine.
Andrea studied it for several seconds.
“Go on,” he said quietly.
“There were no beasts near the structure,” Haldren continued. “Which alone would have been concerning. The surrounding wildlife behaved as if the area were… avoided. Birds did not perch near it. Insects were scarce. Even the wind seemed reluctant to pass through the doorway.”
Andrea’s brow furrowed.
“We secured the perimeter,” Haldren said. “Then entered.”
Several of the scouts shifted subtly.
“The interior was empty,” Haldren said. “No occupants. No furnishings. No signs of worship or habitation.”
“And yet,” Andrea said, “you do not sound relieved.”
“No, my lord.”
Haldren clasped his hands behind his back.
“The atmosphere inside was… oppressive. Gloomy. Sound did not carry correctly. Our footsteps echoed too long, then not at all. Several men reported the sensation of being watched, though no presence could be identified.”
Andrea glanced briefly at the scouts. None met his eyes.
“At the center,” Haldren continued, “we found a casket.”
Andrea looked up sharply. “A coffin?”
“Yes, my lord. Stone. Black. Unmarked. Large enough to house something far bigger than a man.”
Andrea said nothing.
“Beyond that,” Haldren said, “we discovered a passage.”
He paused.
“An underground doorway,” he corrected. “Carved directly into the cathedral floor. Reinforced. Its height alone could allow two chariots to pass side by side.”
Andrea’s fingers tightened on the sketch.
“You entered.”
“Yes.”
The captain’s voice lowered.
“The stair descended deep. Far deeper than any cellar or crypt. The air grew colder. Denser. Our torches burned… poorly.”
One of the scouts swallowed audibly.
“At the base,” Haldren said, “we found another door.”
Andrea waited.
“It was massive. Seamless. Set into black stone unlike the rest of the structure. And upon it were symbols.”
“What kind of symbols?”
Haldren shook his head. “None that any of us recognized. Not divine script. Not arcane notation. Not any language recorded in guild codices.”
Andrea exhaled slowly.
“And you opened it.”
“We attempted to,” Haldren said. “It did not respond. No handles. No hinges. Only pressure seams.”
“And?”
“We began to force it.”
Haldren hesitated.
“That is when I stopped them.”
Andrea looked up sharply. “Why?”
“Because the door felt…” Haldren searched for the word. “Reactive.”
Andrea said nothing.
“When the men placed their hands upon it together,” Haldren continued, “the symbols pulsed faintly. And for a brief moment—”
He stopped.
“The door before us responded.”
The chamber seemed colder.
“I ordered immediate withdrawal,” Haldren said. “One of the guards attempted to step forward regardless.”
Andrea raised an eyebrow. “Attempted.”
“I stopped him physically,” Haldren said. “He was not thinking clearly. None of us were.”
Andrea nodded slowly.
“And your conclusion?”
Haldren straightened.
“My lord,” he said carefully, “in my judgment… this structure matches all known characteristics of an unregistered dungeon.”
The word settled heavily between them.
Andrea leaned back in his chair, eyes lifting toward the vaulted ceiling.
“A dungeon,” he repeated softly.
“Yes.”
Andrea was silent for a long moment.
Finally, he spoke.
“If it is a dungeon,” he said, “it is not one of ours.”
“No, my lord.”
“And if it is not registered…”
“Then it falls under the authority of the Adventurers’ Guild,” Haldren finished.
Andrea nodded.
He stood.
“This matter will be reported immediately,” Lord Andrea said. “You will submit a full written account. Include sketches, measurements, and all personal impressions.”
You might be reading a pirated copy. Look for the official release to support the author.
“Yes, my lord.”
“If the Guild confirms it is a dungeon,” Andrea continued, “then they will handle the investigation.”
He paused.
“And if they do not?”
Haldren did not answer.
Andrea looked once more at the sketch of the black cathedral, its impossible presence at the edge of his land.
“Then,” Lord Andrea said quietly, “something has crossed our border that was never meant to be found.”
The Fourth Floor was no longer still.
It was a wound.
What had once been a vast summoning hall—etched with infernal geometry, ritual grooves, and god-binding arrays—had collapsed inward on itself. Stone walls had buckled and split, the ceiling torn open by earlier impacts, exposing layers of reinforced strata that should never have been visible. Cracks glowed faintly with residual hellfire, and the air itself shimmered under impossible pressure.
At the center of that ruin stood Vaelrix.
No—hovered.
His presence distorted space long before his power did. Dark energy poured from him in visible waves, compressing the air until it screamed. His form had expanded, muscles drawn taut beneath infernal plating as bat-like wings tore free from his back with wet, cracking sounds. Each wingbeat sent concussive pressure outward, pulverizing loose debris into dust.
Above him, a demonic magic sigil rotated slowly—vast, complex, layered with overlapping glyphs that burned in abyssal red and void-black. It pulsed like a malignant star, feeding directly into Vaelrix’s core.
And from that sigil—
Power descended.
A continuous beam of demonic energy crashed downward, reinforced by concussive dark flames that spiraled around it like living serpents. The beam struck the ground with apocalyptic force, swallowing everything within a ten-meter radius outside the collapsed chamber’s remains.
Including Seth.
The impact erased detail.
Stone didn’t shatter—it melted, then vaporized. Reinforced dungeon alloy warped like wax before disintegrating. The ground cratered outward in concentric rings, each pulse chewing deeper into the Fourth Floor’s foundations. Whatever had once been there ceased to exist under the sustained assault.
Vaelrix held the attack.
Ten seconds passed.
Then twenty.
Then thirty.
The beam did not weaken.
If anything, it intensified—dark flames folding inward, compressing, sharpening, burning hotter as Vaelrix poured more of himself into the annihilation. His wings flared wide, anchoring him in the air as the sigil above him screamed with overloaded glyphs.
Nothing could survive that.
No matter how resilient.
No matter how adaptive.
Gradually, Vaelrix narrowed his senses.
He searched for resistance.
For recoil.
For anything.
There was nothing.
No heartbeat.
No pressure feedback.
No signature.
Only absence.
The beam finally cut off with a thunderous snap, the sigil above him dissolving into drifting embers of corrupted light. Vaelrix descended slowly, boots touching down amid molten stone that hissed and cracked beneath his weight.
Dark smoke surged upward, thick and choking, filling every open space of the ruined chamber. It swallowed broken pillars, collapsed walls, and the jagged hole where the beam had struck. Visibility dropped to nothing.
Vaelrix inhaled deeply.
The scent of scorched metal.
Burned magic.
Disintegrated matter.
Victory.
A smirk curled across his face.
“Pathetic,” he muttered, voice echoing unnaturally through the smoke. “All that defiance… for dust.”
The smoke began to thin.
Slowly.
Too slowly.
Vaelrix’s eyes narrowed.
There was no shadow.
No silhouette.
No corpse.
His smirk widened—then froze.
A sound echoed through the chamber.
Thump.
A single heartbeat.
Not faint.
Not distant.
It detonated through the air like a pressure charge, slamming into the walls, rattling loose stone, sending hairline fractures racing across already-damaged surfaces.
Vaelrix’s eyes snapped forward.
Within the thinning smoke, something glowed.
At first it was faint—an indistinct shape, barely visible through drifting ash and vapor. Then the glow intensified, pulsing in rhythm with that heartbeat.
Thump.
The smoke peeled away as if pushed back by force alone.
And Seth stood there.
Upright.
Barely.
His posture was wrong—tilted slightly forward, like a man held together by will alone. The Evo-Suit that once defined his silhouette had vanished beneath layers of radiating energy and dark flame. Vaelrix’s own power clung to him, wrapped around his frame like a second skin, soaked deep into the suit’s structure.
The air around Seth burned.
Not ignited—burned.
Reality itself warped in a tight radius around him, heat distortion bending light as if he were a gravitational anomaly. The Evo-Suit’s surface no longer reflected light; instead, it absorbed it, glowing from within like a collapsing star.
He looked like a miniature sun, forged from stolen hellfire and compressed will.
Then—
The runes ignited.
Not blue.
Not violet.
Black flames erupted from within the radiating energy, tracing rune circuits that reasserted themselves across the suit’s surface. The Evo-Suit adapted in real time, its systems devouring Vaelrix’s demonic output, breaking it down, rewriting it, making it obedient.
Vaelrix felt it.
Felt his own power echoing back at him—refined.
His smile vanished.
“That’s—” he began.
The Evo-Suit’s heart beat once more.
And Seth moved.
There was no acceleration curve.
No buildup.
One moment he stood ten meters away—
The next, he was there.
Seth crossed the distance at the speed of light, space collapsing between steps as if distance had simply been denied. Vaelrix barely registered motion before a knee slammed into his face with catastrophic force.
Bone cracked.
Air detonated.
Vaelrix was driven backward like a meteor, his body smashing through remaining wall structures and burying itself deep into reinforced dungeon stone. The impact carved a massive crater, debris exploding outward as the ceiling groaned under the sudden shock.
Stone began to fall.
Vaelrix tore himself free from the wall, dust and fragments cascading off his armor as he hovered again, wings beating violently. Blood—dark and smoking—ran from his mouth as his expression twisted into pure fury.
The ceiling above finally gave way.
Chunks of reinforced stone crashed down around them, the chamber collapsing further into chaos.
Vaelrix roared.
Not a shout—a command.
The sound carried power, a shockwave of infernal authority that slammed through the crumbling hall, shattering remaining pillars and forcing the air into violent oscillation. Above his head, a dark thorny halo manifested, jagged and asymmetrical, crowned with forward-curving horns that pulsed with abyssal energy.
His aura surged.
Expanded.
Out scaled.
For a moment, the pressure in the chamber rivaled divine descent.
Seth straightened.
The radiating energy around him stabilized, black flames tightening along the Evo-Suit’s rune channels. His stance shifted—lower, balanced, predatory.
They dashed toward each other simultaneously.
Vaelrix thrust his overpowered spear forward, the weapon screaming as it carved through space, its tip wrapped in condensed hellfire sharp enough to slice concepts.
Seth met it head-on.
His claws retracted forward, reinforced by layered energy plating as he struck the spear mid-lunge. The collision cancelled both attacks outright, releasing a shockwave that tore through the chamber like a horizontal explosion.
Stone disintegrated.
Air collapsed.
Mid-momentum, Seth twisted.
His body rotated with impossible precision, movement flowing seamlessly into offense as he drove a clean side kick into Vaelrix’s ribs.
The hit landed.
Vaelrix slammed sideways into the chamber floor, the impact sending a shock through the dungeon’s foundation and carving another crater deep into the Fourth Floor.
He emerged instantly, launching a flurry of precision strikes downward, spear flashing in controlled arcs aimed exactly where Seth stood—
But Seth was no longer there.
He dodged, flipping backward through falling debris, the Evo-Suit compensating mid-air as he opened distance with a perfect backflip, landing lightly amid rubble.
Vaelrix moved to pursue—
And froze.
His limbs refused to respond.
He looked down.
The ground beneath his feet had swallowed him.
Stone flowed upward like liquid earth, locking his boots in place, crawling up his legs in restrictive bands. Dark energy flared as he attempted to break free—
Too late.
Behind him, Agatha’s final chant completed.
The air darkened.
From Vaelrix’s own shadow, chains ascended—thick, black, rune-etched links that wrapped around his standing collar, crossed his neck, locked his wrists, bound his ankles and waist. Each chain hummed with ascended magic, layered with suppression glyphs that devoured power output.
Pairs of thorny pillars erupted from the ground, gripping his arms and forcing them upward, locking him in place.
Behind him, the earth split again.
A centipede-like immobilizer burst forth, dozens of thorny wires lashing out, clinging to his body, dragging him backward into reinforced restraints as alloy poles impaled through non-lethal but vital locking points—sealing joints, pinning muscle groups, suppressing both physical movement and energy flow.
Vaelrix screamed.
The sound was raw.
Unfiltered.
Powerless.
When it ended, he hung suspended—immobilized, restrained, contained.
He lifted his head slowly.
Looked at Seth.
Then at Agatha.
His eyes burned with hatred as his expression twisted into a deep, furious frown.
The chamber fell silent—save for the slow, steady heartbeat of the Evo-Suit.
The Fourth Floor should have collapsed.
By all logic—mundane, magical, infernal—it should have caved in on itself and buried everything beneath thousands of tons of broken dungeon strata.
It didn’t.
Agatha stood near the chamber’s fractured edge, one arm raised, fingers spread as violet light poured from her palm into the ruined expanse. The spell unfurled outward in a vast radius, violet vines erupting from the stone like living arteries. They threaded through shattered pillars, wrapped around broken ceiling plates, fused cracked walls together, and anchored collapsing sections in place.
The vines did not beautify the ruin.
They merely held it together.
The floor looked like the aftermath of an apocalypse—molten scars burned into stone, craters layered over craters, jagged silhouettes of collapsed architecture frozen mid-fall. It was a landscape abandoned by order, preserved only by force.
Agatha exhaled slowly as the spell completed, the glow dimming but not fading.
“Don’t mistake this for restoration,” she said coolly. “It’s just containment.”
Vaelrix laughed.
The sound was hoarse, distorted by the chains biting into his body, by the alloy poles pinning him in place, by the seal devouring his power even as he tried to force it outward. His wings twitched uselessly behind him, pinned by thorny restraints and shadowed bindings.
“Foolish mortals,” he spat. “To use such despicable tactics… you are no different from us demons.”
Seth turned his head slightly, the radiance around him flaring and dimming in slow pulses like a star breathing.
“Says the one who couldn’t stop gloating long enough to notice he was losing,” Seth replied flatly. “You talked a lot about superiority for someone who’s chained to the floor.”
Vaelrix snarled. “If I wanted, you'd be dead.”
Seth’s gaze shifted fully to him.
“How reassuring,” he said. “And look where that confidence got you.”
“You think you’re clever,” Vaelrix growled. “But only foolishness runs through you, mortal.”
“What now?” Seth asked. “Excuses for your own downfall?”
Vaelrix’s eyes burned brighter. “You think you’ve won? Don’t let illusions cloud your thoughts!”
“I didn’t say I won,” Seth replied. “I said not going all out from the beginning is what determined the present outcome.”
Vaelrix laughed again, harsher this time. “You speak as if you understand everything. Once I am free from this seal, you will beg me for a painful death.”
Seth tilted his head. “I never claimed omniscience. But what makes you so certain?”
Vaelrix straightened as much as the restraints allowed, his aura surging violently. “I am one of the high-ranked demons beneath the Seven Thrones of Hell! Such a seal is nothing to me!”
He roared.
Infernal energy erupted from his core in a violent surge, slamming into the restraints with raw force. The chains screamed under the pressure, glyphs flaring as the seal strained to hold. The chamber trembled, loose debris rattling as the expelled power blasted outward.
Seth watched.
Unimpressed.
“Muscle brain,” he muttered.
Agatha stepped forward—but stopped five meters behind Seth. Even now, she respected the unstable field around him. The radiance pouring off the Evo-Suit still warped the air, heat and power radiating like a furnace.
She glanced at his silhouette, eyes narrowing.
“You took your time,” Seth said without looking at her.
“Probably,” Agatha replied.
She studied him openly now. “How long before that energy dies down?”
“Hard to say,” Seth answered. “A day, maybe more. Either the suit absorbs it completely… or it bleeds off naturally.”
“You think so?”
Seth didn’t respond immediately.
Agatha’s eyes shifted to his posture, the minute tremors beneath the controlled stance.
“…The spell took longer than you said it would,” Seth finally said, turning to face her.
Agatha blinked once.
“Oh,” she said lightly. “You noticed.”
“Yes,” Seth replied. “I kept track. Every second. What else were you doing?”
Agatha folded her arms. “Layering. Field stabilization, debris suspension, reinforcement arrays to keep the chamber from collapsing too early.”
Seth paused.
“You were double-casting,” he said.
“That’s one way to put it.”
“That’s rare,” Seth said.
Agatha smiled—a small, unapologetic grin. “You can phrase it however you like.”
Seth studied her for a moment longer, then turned his attention back to Vaelrix.
“So,” he said. “How long does this seal hold? A day? A week?”
Agatha followed his gaze. “As long as he still lives.”
Seth raised an eyebrow. “That powerful?”
“Yes,” she replied calmly. “The cost is steep. Large magic capacity consumption. Even for someone at my level, I can maintain it indefinitely.”
“What about master-class casters?”
“They’d collapse,” Agatha said simply. “Exhaustion at best. Mana burnout at worst.”
“I see.”
Agatha glanced sideways at him. “In other words, I arrived at the right time.”
Seth snorted. “No. You didn’t.”
She stopped. “Excuse me?”
“You heard me.”
Agatha frowned. “You were on the brink of death. If I hadn’t intervened”
“I was holding the battlefield,” Seth interrupted. “You could say I had the upper hand.”
Agatha stared at him.
“If that fight had dragged on,” she said slowly, “you would have died.”
“If it had dragged on,” Seth countered, “I'll probably win.”
They locked eyes.
Neither yielded.
“…Are you sure you’re okay?” Agatha finally asked. “You look like you’re being cooked alive in there.”
Seth glanced down at himself. The Evo-Suit still glowed intensely, flames licking inward instead of out.
“I’m fine,” he said. “It’s just warm.”
He turned back to the devastated chamber. “How bad is it?”
Agatha followed his gaze.
“…Awful,” she admitted. “I told you so.”
“Huh?”
“If you’d listened to my warning, none of this would’ve happened.”
Seth’s jaw tightened. “No. If you hadn’t used my blood instead of yours, the outcome would’ve been different.”
Agatha scoffed. “Trying to shift your guilt onto me? How mature.”
Seth sighed.
“Aid,” he said.
The system responded instantly.
[Casualty Assessment — Fourth Floor]
Structural Integrity Loss: 95.3%
Agatha winced. “Are you planning to fix this… or abandon it?”
“Neither,” Seth replied. “Not entirely.”
He queried Aid again—this time about the Sixth Floor.
[Sixth Floor Construction: 51% Complete]
Seth turned to Agatha. “Did you summon any minions for reconstruction?”
She shook her head. “I don’t have familiars suited for labor. Most of mine are combat-oriented.”
“Figures.”
“Your units are better suited anyway,” she added.
Seth nodded once.
“Aid,” he said. “Upon completion of the Sixth Floor, begin reconstruction of the Fourth.”
[Order Confirmed]
He turned back toward Vaelrix, who was still straining uselessly against the seal.
“I can feel his magic output,” Seth said.
Agatha nodded. “The seal consumes it—and expels the excess outward. Once his reserves are depleted, it resets.”
“…So it absorbs and vents,” Seth murmured.
An idea clicked.
“Aid,” he said again. “Deploy energy extraction units.”
From the rear of the chamber, foreign architecture unfolded—conversion panels, anchored poles, and extraction arrays sliding into place with mechanical precision. They locked into position around Vaelrix, intercepting the energy being expelled by the seal.
Seth watched the readings stabilize.
“Route it to the dungeon core,” he ordered. “Primary and backup.”
Agatha stared.
“…I never thought you’d go that far.”
“We can’t waste this,” Seth replied evenly. “You want some? You could charge up.”
Agatha recoiled instantly. “Demonic energy? Absolutely not. I enjoy my sanity.”
“You could handle it.”
“I could,” she agreed. “But I won’t. Corruption isn’t worth the gamble.”
Vaelrix finally stopped struggling.
His eyes locked onto the alien constructs draining his power.
The look he gave them was pure, unfiltered disgust.
The dungeon hummed—fed by a demon who had thought himself untouchable.
