Chapter 83: Sector Three

The air beneath the Vanguard Citadel did not merely feel cold; it felt heavy, thick with the damp, mineral stench of ancient granite and stagnant water.

A spiral staircase carved directly into the bedrock descended three hundred feet below the surface. Every fifty paces, an enchanted brass wall-sconce provided a dim, sputtering pool of amber light.

Above, the distant thrum of the academy—marching boots, training hall impacts, ringing iron—gradually faded, replaced by the rhythmic, echoing drop of condensation hitting wet stone.

Tink. Tink. Tink.

Mirain walked ahead without hesitation, her crimson cloak pulled tight around her shoulders, her leather boots making soft, deliberate contacts against the damp stairs. Her right hand rested lightly on the pommel of her crimson rapier.

Two paces behind her, Valerian moved like a ghost. His tread made no sound at all—a habit beaten into his bones during his years surviving the wild borderlands, where stepping on a dry twig meant an arrow through the throat.

"The mana down here is spoiled, master," Aurelix noted in his mind, her tone dropping its usual playful banter for a sharper, predatory edge. "It tastes like stagnant bathwater mixed with crushed copper. Something is leeching off the ley-lines beneath this rock."

I feel it, Valerian replied quietly through their mental link. Keep your aura tight. If you leak even a speck of primordial flame, the Sanguis girl in front of us will pick it up.

"Pah. As if I’d be so careless around a little blood-maggot."

Valerian kept his sensory perception focused outward. Through the black cloth over his eyes, the world was rendered in sharp, spatial geometry: the curve of the subterranean masonry, the structural load points of the archways, and the faint, beating pulse of Mirain’s heart ahead of him.

Her heartbeat was remarkably slow—forty-two beats per minute.

Unflappable.

Cold.

"You aren’t carrying a torch," Mirain said smoothly without turning her head.

"Don’t need one," Valerian replied, his voice flat. "Light draws attention. If something is waiting in the dark, I’d rather see it before it sees me."

"You’re blindfolded."

"I have good ears."

Mirain let out a faint, quiet exhale through her nose—not quite a laugh, but the closest thing to one she ever allowed herself.

"The instructors say you fought through the entrance exam without drawing a single spell array. They think you’re a pure physical enhancer who hides his mana signature out of paranoia."

"Instructors talk too much."

"They do," Mirain agreed, stopping at the base of the staircase.

They had reached a wide, vaulted subterranean corridor. Heavy iron support beams reinforced the ceiling, and thick copper conduit pipes ran along the walls, humming with suppressed magical energy—except for the massive central pipe marked SECTOR 3, which hung stone-cold and silent.

At the far end of the hall stood the entrance to the primary logistics vault: a massive, ten-foot-tall door made of solid reinforced iron, bound with silver warding runes.

The door was standing three inches ajar.

The heavy silver lock mechanism hadn’t been picked or shattered by brute force.

It had been melted.

A dark, bubbling residue clung to the twisted metal, giving off a sharp, chemical stench that smelled like burnt hair and sulfur.

Mirain knelt beside the door, dipping two gloved fingers into the dark residue. She brought them close to her face, sniffing once, her cold crimson eyes narrowing.

"Corrosive acid," she murmured. "High-tier alchemical compound. The kind sold exclusively through black-market syndicates in the lower capital."

"Or made in a back-room laboratory by someone who knows what they’re doing," Valerian added, stepping past her to inspect the inner seam of the iron door.

He reached down, his gloved fingers tracing a microscopic streak of dried, blackened fluid near the floor.

"Blood."

Mirain stood up instantly, her hand gripping her rapier hilt tighter.

"Sanguis blood?"

"No," Valerian said, sniffing the air subtly beneath his blindfold.

His refined senses, honed by his sealed dragon bloodline, instantly categorized the iron content and vitality of the stain.

"Human, but corrupted. Low vitality, heavy trace elements of necrotic mana. Whoever bled here was dying before they even reached this door."

Mirain didn’t waste time asking how a commoner mercenary could distinguish necrotic mana traces in dried blood with his eyes covered.

She simply pushed the heavy iron door open.

It swung inward with a low, agonizing screech.

Inside, the Sector Three Logistics Vault opened into a vast, cavernous hall filled with towering wooden crates, iron weapon racks, and rows of stone pedestals holding sealed mana-crystal containers.

Or rather, what was left of them.

Half the crates had been violently smashed open. Weapon racks were overturned, steel longswords lying broken on the cobblestones like snapped twigs.

The central pedestal—where the primary ward-stone catalyst for the eastern perimeter should have sat—was completely empty, its glass housing shattered into thousands of tiny, shimmering shards.

"The ward-stone is gone," Mirain said softly, her voice dipping into a dangerous, icy register.

"Without that catalyst, the eastern perimeter wards will suffer a thirty percent decay within forty-eight hours."

"They didn’t just take the stone," Valerian said, walking slowly down the central aisle, his iron sword still sheathed at his hip.

He stopped beside an overturned wooden crate stamped with the Imperial Crest.

"Look at the crates."

Mirain stepped up beside him.

The crate had contained high-grade mana-extraction tools, silver needles, and enchanted glass vials used by the academy’s medical division.

Every single glass vial was missing.

The heavy enchanted iron weapons nearby had been completely ignored.

"They didn’t come for weapons or gold," Mirain realized, her brow furrowing. "They came for medical equipment and warding components."

"And they weren’t alone," Valerian muttered.

Before Mirain could respond, Valerian’s left hand shot out, catching her by the front of her dark leather mantle and yanking her back three feet with brutal, effortless leverage.

SCHLICK!

A jagged, bone-white spur shot out from the shadow of a smashed crate, impaling the exact patch of stone where Mirain had been standing a fraction of a second prior.

The stone shattered like brittle glass under the sheer force of the thrust.

Mirain didn’t scream. She didn’t stumble.

The moment her feet touched the ground, her crimson rapier cleared its scabbard with a sharp, ringing whisper of steel, her blood-red mana flaring around her blade like a halo of crimson fire.

From the darkness between two fallen supply crates, a shape dragged itself into the dim light of the wall sconces.

It had once been a man—a low-ranking academy night-guard, judging by the shredded remnants of blue wool uniform clinging to its torso.

But his flesh had been peeled back from his chest and shoulders, pinned open by black iron staples.

His arms were unnaturally lengthened, the finger bones elongated into razor-sharp, ivory blades.

His eyes were gone, replaced by hollow, bleeding sockets, and his jaw hung loose, dripping black, viscous bile onto the floor.

"A flayed construct..." Aurelix hissed in Valerian’s mind, her spiritual form tensing instantly. "Master... that is Xul’Gorgoth’s handiwork. The Mad Doctor’s alchemical flesh-craft."

I know, Valerian thought, his face darkening beneath his blindfold. The lower vaults are already infested.

The creature let out a wet, raspy screech—a sound like meat being torn in half—and lunged forward, its bone-blade arms whistling through the air toward Mirain’s neck.

Mirain stepped forward to meet it, her rapier thrusting out in a blinding crimson arc.

"Sanguis Art: Piercing Crimson!"

THWIP-THWIP-THWIP!

Three razor-thin beams of concentrated blood-mana pierced the creature’s chest, blowing basketball-sized holes through its rotting ribcage.

Black blood sprayed across the stone floor.

The impact hurled the construct backward five feet, but as it hit the ground, the severed muscle fibers and exposed bone began to twitch, black thread-like parasites knitting the flesh back together at an unnatural, terrifying speed.

"It doesn’t feel pain," Mirain growled, stepping into a low combat stance. "And its core isn’t in the chest."

"It doesn’t have a core," Valerian said calmly, walking forward past her. "It’s a puppet. The brain stem is destroyed, but the spine is packed with alchemical wire."

"Valen, fall back!" Mirain commanded, her voice sharp. "Physical attacks won’t stop a dark flesh construct without high-grade mana reinforcement—"

Valerian didn’t fall back.

He didn’t draw his sword.

He didn’t unleash a surge of dragon mana, nor did he allow a single spark of his true bloodline aura to leak into the room.

He simply took one precise, measured step forward.

As the flayed construct leaped into the air, its bone-blades sweeping down toward his collarbone, Valerian ducked his head by two inches—just enough for the lethal bone-spur to graze the air above his ear.

In the same fluid motion, Valerian’s right hand shot forward, grabbing the creature’s extended wrist.

He planted his heel into the stone, twisted his hips, and used the construct’s own momentum against it, slamming its heavy, rotting torso head-first into the stone floor with a bone-shattering CRUNCH.

Before the creature could writhe or knit its flesh back together, Valerian brought his heel down directly onto the back of its neck.

SNAP.

The biomechanical precision was absolute.

His boot crushed the upper cervical vertebrae and severed the black alchemical wire running along the spine in a single, un-reinforced physical strike.

The construct gave one final, violent twitch, its limbs going completely limp, the black bile pooling harmlessly around Valerian’s scuffed leather boot.

The vault fell instantly silent, save for the distant tink-tink-tink of water dripping from the ceiling.

Mirain stood five paces away, her crimson rapier still glowing with blood-mana, her cold eyes fixed entirely on Valerian.

She didn’t look at the dead construct.

She looked at his feet, his posture, and the complete lack of breath control disruption in his chest.

"No mana," Mirain said slowly, her voice dangerously quiet.

"You didn’t use a single drop of mana reinforcement. You calculated the structural weakness of an alchemical construct’s spine and executed a leverage throw in complete darkness."

Valerian slowly pulled his boot back from the creature’s crushed neck, wiping a smear of black bile off the leather against a wooden crate.

"I told you," Valerian said flatly, pulling his scuffed coat tight over his shoulders. "I spent my youth in the borderlands. You learn where to hit things when you can’t afford expensive magic."

Mirain stared at him for three long seconds.

The silence between them stretched, thick and suffocating.

Finally, she lowered her rapier, the crimson mana fading from the blade with a soft hiss as she sheathed it at her waist.

"This construct wasn’t acting on instinct," Mirain said, turning her attention back to the empty pedestal in the center of the room.

"Someone created it here, inside the academy walls, using a missing night-guard as raw material. The ward-stone was stolen to blind the eastern perimeter sensors."

"Which means whoever is doing this," Valerian added, "is preparing for something much bigger than stealing medical supplies."

Mirain reached into her coat, pulling out a small silver communication rune tablet.

She tapped it twice, sending an encrypted priority signal directly to the Archmages’ Council.

"The academy leadership thinks the Vanguard Division is a safe fortress," Mirain whispered, her crimson eyes gleaming with cold, sharp intellect in the dim light.

"They are blind. The corruption isn’t coming from outside the walls, Valen... it’s already rooted beneath our feet."

She turned toward the exit, her crimson cloak billowing behind her.

"Come, Assistant. We have a report to file—and a traitor to hunt."

Valerian stood in the dim vault for a moment longer, looking down at the dead construct.

Inside his chest, deep beneath his sealed dragon cores, the cold memory of heavy iron, falling rain, and the thud of a guillotine blade gave a faint, phantom ache.

"The game is starting, little master," Aurelix purred softly in his ear.

Valerian turned and followed Mirain into the dark.
