Chapter 120: Subterranean Transit

The morning air outside the Sector Zero administrative gates did not carry the damp fog of Sector B or the sulfurous heat of the Black-Glass Canyon.

It was cold, dry, and stagnant—tasting faintly of ozone and ancient stone dust.

An iron transport carriage, suspended from heavy steel cables running along the vaulted ceiling of the subterranean transit tunnel, groaned as its heavy gears engaged.

Inside the carriage, Cell One sat on narrow wooden benches.

Casper von Valerius leaned forward, his broad shoulders hunched as he methodically polished the guard of his right arming sword with an oily rag.

He had abandoned his fine velvet House Valerius tunic in favor of reinforced leather brigandine, stripped of all silver decorative wire.

"No sulfur, no black glass, no heat," Casper muttered, looking out through the narrow iron-grated window at the dark tunnel walls rushing past.

"Just miles of wet granite and static air."

He sighed.

"I hate Sector Zero already."

"Sector Zero isn’t an open trial ground, Casper," Lyra said softly from the opposite bench.

She was checking the alignment of the focus crystals in her spatial staff, her fingers working with quick, practiced precision.

"It’s the original foundation of the Citadel. The ley lines beneath the central archives run sixty miles deep. Spatial spells lose thirty percent of their stability down here because of the raw mana density."

Solene Sol sat near the forward door of the carriage, her white cape neatly folded beside her seat.

Her ivory rapier lay across her knees, her pale fingers resting lightly on the hilt.

She hadn’t spoken since they boarded the transit carriage at dawn.

Her icy blue eyes were fixed entirely on Valerian.

Valerian sat at the far end of the bench, relaxed and still.

He wore his scuffed wool coat, his dark linen blindfold tied securely across his face.

Under his left sleeve, the dark-mithril suppressor guard remained cold and silent, keeping the three dragonic cores within his spiritual realm in perfect, quiet harmony beneath Aurelix’s golden shroud.

"You’re quiet today, Valen," Solene said, her voice cutting through the steady clatter of the iron wheels.

"No counts? No field inventories?"

Valerian turned his blindfolded head toward her.

"The transit journey takes forty-two minutes, Solene. The environment is stable, and our equipment was inspected before departure."

A pause.

"There is nothing to report."

Solene released a short breath that was half a laugh and half a sigh.

"So you’re dropping the auditor act?"

"It was never an act, Solene," Valerian replied smoothly.

"Information is merely the tool required to keep people alive in volatile environments."

His head turned slightly toward the dark tunnel ahead.

"In Sector Zero, the volatility changes from physical hazards to structural politics."

"Master..."

Aurelix’s golden voice echoed softly in his mind, her nine ethereal tails rustling against his consciousness like silk.

"The copper cable above us just experienced a subtle resonance spike. Someone is tapping into the transit line’s mana conduits from the lower drainage ducts."

Valerian didn’t shift his posture.

"A spatial tracking ward?"

"No," Aurelix murmured, her amber eyes narrowing within his spiritual realm.

"It’s a signal relay. The Mad Doctor knows we are inside this carriage. He’s tracking our depth."

Before Valerian could process the warning, a sharp metallic screech echoed down the length of the transit tunnel.

The iron carriage jolted violently.

Casper was thrown from his bench onto the wooden floor.

The overhead steel cables whined under sudden, massive tension as the carriage’s forward momentum ground to a dead halt.

"Hold!" Solene snapped.

Her ivory rapier cleared its sheath in a single fluid motion.

She braced her boots against the iron floor, her eyes darting toward the ceiling grates.

"Did the cable snap?" Casper asked, scrambling back to his feet and drawing both arming swords.

"Cables don’t snap with a clean metallic stop," Lyra warned.

She raised her staff as a pale blue barrier shimmered around Cell One.

"The emergency brake locks were engaged from the external control junction."

Through the iron-grated windows, the darkness of the tunnel was thick and absolute.

The luminescent mana lanterns lining the transit walls had all been extinguished, leaving only the dim blue glow of Lyra’s barrier to illuminate the cramped space.

Then came the sound.

It was not the clanking of automaton armor.

Nor was it the boots of Imperial soldiers.

It was a wet, skittering scrape.

Dozens of sharp, chitinous limbs crawled along the iron exterior of the carriage walls.

"Chitin-crawlers?" Casper grunted, taking a high guard near the side door.

"In an administrative transit tube?"

"Not natural crawlers," Valerian said.

His voice dropped into a focused, quiet tone as he stood from the bench.

"These creatures are bound with flesh grafts."

A pause.

"The Mad Doctor’s residual units."

The iron roof of the carriage groaned as heavy weight settled directly above them.

SCREECH!

A razor-sharp, dark-crimson claw punched straight through the two-inch iron roof, missing Lyra’s shoulder by inches.

The claw was coated in a dark, bubbling alchemical brine that instantly began melting the iron plating where it touched.

"Lyra, collapse the forward window grate!" Solene ordered.

Her rapier thrust upward through the newly created hole in the roof.

The blade struck something hard and dense, freezing the creature’s limb instantly with a sharp burst of glacial frost.

But three more claws smashed through the roof panels, tearing the iron ceiling open like damp paper.

"We can’t defend inside this box!" Casper yelled.

He parried a descending claw that shattered the leather strap of his left shoulder guard.

"We’re trapped!"

"We aren’t staying in the box," Valerian said calmly.

He reached out with his left hand and grabbed the heavy brass latch of the carriage’s emergency side door.

He didn’t channel mana.

He didn’t draw a dagger.

He simply pulled the mechanical release bar downward with a sharp jerk, unseating the secondary locking pins that held the iron door against the tunnel wall.

The heavy door kicked outward, slamming hard against the granite wall of the tunnel and creating a narrow two-foot gap.

"Out. Now."

Valerian’s command carried through the carriage.

Solene didn’t hesitate.

She glided through the gap first, her frost-covered rapier carving a clear arc through the darkness outside.

Casper followed immediately, hauling Lyra by the collar to clear her through the narrow exit just as the carriage roof completely caved in beneath the weight of three massive, dark-fleshed constructs.

Valerian stepped through last, sliding onto the narrow two-foot maintenance ledge between the carriage and the rough granite tunnel wall.

The tunnel was filled with the foul, acrid stench of alchemical brine and burning copper.

Illuminated only by the pale blue light of Lyra’s spatial staff, three monstrosities crouched atop the wrecked carriage.

They were five-foot-tall hybrid quadrupeds.

Their torsos were grafted from cave-drake forelimbs, while their heads had been replaced with glowing red-gemstone cores that pulsed in synchronization with the subterranean ley lines.

"They’re targeting our mana signatures!" Solene called out, taking a low stance on the narrow ledge.

"Every time Lyra raises a barrier, their head gems brighten!"

"Then turn the barriers off, Lyra," Valerian said softly.

He walked steadily along the granite ledge until he stood between Cell One and the crouching beasts.

"Turn them off?!" Casper shouted over the roaring hiss of the creatures.

"Valen, we’re on a two-foot ledge over a hundred-foot drop!"

"They are blind constructs, Casper," Valerian explained smoothly.

His posture remained completely relaxed despite the razor-sharp claws clicking against the iron roof only a few feet away.

"They do not possess eyes. They navigate entirely by tracking high-density mana output and thermal resonance."

He tilted his head.

"Solene’s ice magic and Lyra’s spatial barriers are like lanterns in a dark room to them."

Solene instantly lowered her rapier’s frost aura.

Her breath caught as she realized he was right.

The moment the magic faded, the three creatures raised their heads.

Their red gemstone cores flickered in confusion as their target signatures vanished.

"Master..." Aurelix whispered inside his mind.

"The lead construct is preparing a localized kinetic burst. It’s trying to flush us out with raw shockwaves."

"Not if its internal focus is disrupted," Valerian replied silently.

Valerian reached into his pocket and pulled out a small standard copper coin.

A simple piece of pocket change.

He didn’t coat it in Blood Shadow mana.

He didn’t imbue it with dragonic energy.

He simply flicked his thumb.

The copper coin spun through the air toward the far side of the transit tunnel, sixty feet behind the creatures.

PING!

It struck an iron support cable with a sharp, ringing note.

The mechanical vibration echoed through the hollow tube.

Instantly, all three drake hybrids whipped their heads toward the sound.

Driven by their crude internal instincts, they lunged from the carriage roof in a ferocious, synchronized leap, diving straight toward the distant iron cable.

There was no floor beneath it.

The three massive constructs plummeted past the edge of the maintenance ledge, tumbling into the pitch-black abyss of the lower drainage shafts below.

Deep, echoing thuds resounded seconds later.

Then came complete silence.

Casper blinked into the darkness, his twin swords still raised, his jaw hanging open.

"A... a copper coin?"

He slowly looked toward Valerian.

"You beat three high-tier alchemical beasts with a single copper coin?!"

"They were engineered for combat against spellcasters who deploy loud, high-density mana," Valerian said, turning back toward the maintenance walkway.

"A copper coin costs less than a breath of air and produces a far clearer acoustic resonance against high-tension steel."

Solene sheathed her rapier with a soft, decisive click.

She stepped closer to Valerian, her icy eyes searching his blindfolded face in the dim light.

"No grand battle. No secret weapons. Just basic observation."

Her voice carried a strange mixture of respect and intense curiosity.

"You really do see the world differently, don’t you, Valen?"

"I see things as they are, Solene," Valerian replied quietly.

"People complicate threats because they react with fear instead of observation."

He began walking.

"A beast, a trap, or a political faction all operate on basic rules."

His stylus tapped lightly against his ledger.

"Identify the rule, and the danger resolves itself."

Lyra let out a deep sigh of relief, lowering her staff.

"The transit track is blocked ahead, but the maintenance walkway leads directly into the lower archives of Sector Zero. We can reach the entry gates on foot in twenty minutes."

"Then we walk," Solene declared.

She stepped forward to take the lead along the narrow ledge.

"Cell One still has a trial to win."

---

Twenty minutes later, the dark maintenance tunnel opened into a breathtaking subterranean chamber.

Sector Zero was not a fortress or a military camp.

It was an underground city forged during the First Era.

High vaulted ceilings carved from white marble stretched hundreds of feet overhead, illuminated by massive floating crystal spheres that radiated warm, artificial sunlight.

In the center of the grand plaza stood the High Archive.

It was a colossal eight-story structure made of polished black granite, housing the ancient records, soul-seals, and historical foundations of the Imperial Realm.

Dozens of elite cadet cells from across the entire Citadel were already gathered in the plaza, their colorful flags rustling in the soft, engineered breeze flowing through the ventilation domes.

Standing atop the marble podium at the entrance of the High Archive was Representative Mirain Sec Sanguis, flanked by two senior Imperial officers clad in gold-and-black ceremonial plate.

As Cell One emerged from the transit archway—scuffed, dusty, but completely unharmed—Mirain’s violet eyes locked onto Valerian.

A subtle, approving smile touched her lips.

"Attention, cadets of the Third-Tier Trials!"

Mirain’s voice echoed across the massive plaza, amplified by high-grade acoustic runes.

"You have survived the trial grounds of Sector Four and Sector Six."

She gestured toward the massive brass-reinforced doors of the High Archive.

"But Sector Zero tests neither your brute force nor your physical speed."

Her voice rang clear and authoritative.

"Inside these walls lie the original foundations of our realm."

She extended one hand toward the sealed archive doors.

"Your objective for the Third-Tier Trial is simple: locate and retrieve the missing soul-record scrolls of your respective House lineages."

The cadets fell silent.

"The first three cells to present their verified records to the High Council will secure absolute entry into the Officer Core."

The crowd erupted into excited murmurs.

Swords were unclasped.

Spellbooks were opened.

Maps appeared in dozens of hands.

Casper rolled his shoulders, a confident grin returning to his face.

"Searching an old library? Sounds like a vacation compared to sulfur vents and iron automatons."

"It is not a vacation, Casper," Solene warned.

Her eyes narrowed as she spotted several shadowy figures clad in the dark robes of the Imperial Secret Commission lurking near the archive doors.

"The High Archive is a labyrinth of ancient warding seals. One wrong step and an unverified intruder is erased by the building’s internal defense arrays."

Valerian stood quietly at the back of the group, his hands resting naturally at his sides beneath his wool coat.

Under his left sleeve, the dark-mithril guard gave a soft, rhythmic warmth.

Not a warning of danger.

Recognition.

Deep within the subterranean vaults of the High Archive, thirty levels beneath the public galleries, something was calling to the three dragonic cores resting within his soul.

The ancient records of the First Sovereign were down there.

"Master..."

Aurelix whispered, her golden form flickering gently beside his shoulder, invisible to all others.

"The path to the deep vaults is open."

Her smile was audible in her voice.

"The High Council has no idea what they have invited inside their library."

Valerian adjusted his dark linen blindfold slightly.

His expression remained calm, cold, and entirely focused.

"Let us begin," Valerian said softly.
