The main arterial tunnel widened into the Old Municipal Vault Chamber—a subterranean vault framed by colossal basalt archways and iron-reinforced concrete pillars.
Dense, violet Aether-Miasma swirled across the shattered marble tiles like a living fog, illuminated by three high-grade Vanguard mana beacons staked into the stone floor. The beacons cast a harsh, unnatural white glare across the chamber, cutting through the purple gloom and revealing the massive, star-iron vault door at the far wall.
Standing directly before the vault threshold were three figures clad in dark crimson Vanguard plate—the signature armor of House Craig’s elite internal enforcement wing.
At the center stood Captain Vane Craig—a distant cousin of the main line, a battle-hardened warrior whose heavy broadsword trailed a thin, sputtering thread of Tier C- Crimson Flame. Flanking him were two elite Vanguard enforcers, one wielding a pair of runic executioner axes, the other holding a heavy tower shield etched with House Craig's high-district crest.

As Squad Alpha stepped out from the arched corridor, their boots crunching against the calcified grit, Captain Vane turned his head slowly. His scarred, rigid face twisted into a cold, condescending smirk.
"So," Vane rasped, his voice echoing off the vaulted basalt ceiling. "The discarded trash of House Craig actually managed to crawl down to the five-hundred-foot mark."
Marcus dropped his knee instantly, slamming his vanadium-plated tower shield into the marble floor with a heavy CLANG! Timothy ducked behind him, his repeating crossbow leveled, his fingers steady on the stock. Sabrina stood half a pace to the left, her silver rapier held at a low guard, her pale blue eyes tracking the fiery aura pulsing around Vane’s broadsword.
Rian stepped forward to the center of the formation, his slate-grey coat unbuttoned, his dark eyes locking onto Vane’s crimson crest with quiet, unbothered composure.
"Lord Valen sent his personal enforcement unit," Rian said flatly, his voice carrying no panic, no anger, only clinical observation. "I expected him to send assassins, not house guards."
Vane let out a harsh, dry laugh, resting his flaming broadsword against his shoulder.
"Lord Valen doesn't waste assassins on a Level 1 defective, Rian," Vane sneered. "He sent us to ensure you don't return to the upper district with high-tier cores. The academy leaderboard score you logged yesterday embarrassed the main line. Lord Valen's instructions were simple: break your limbs, shatter your life-tether crystals, and leave your squad pinned to the catacomb floor until the deep spatial tear opens."
"He thinks a leaderboard score is a personal insult," Sabrina noted, her voice dropping into a razor-thin, icy whisper. "Typical high-district arrogance."
"Silence, runaway!" the ax-wielding enforcer barked, flaring his kinetic aura. "You're dealing with House Craig's Vanguard! Yield your weapons and hand over your spatial ring, or we sever your limbs before breaking your crystals!"
Rian didn't look at the enforcers. He looked down at the marble floor beneath his soles.
Living Shadow... expand.
Beneath his leather boots, the Level 3 Living Shadow surged across the marble tiles, its liquid dark mantle extending six full meters in every direction. Its four violet eye-slits flickered deep within the obsidian pool, silently drinking in the dense atmospheric miasma leaking from the vault door behind Vane’s squad.

"Marcus, lock the shield-bearer," Rian commanded quietly, his voice cutting through the hum of the mana beacons. "Timothy, suppress the ax-man’s line. Sabrina... take Vane’s right flank."
Vane’s eyes narrowed as he heard the banished noble issuing orders with absolute, unshakeable authority. "Arrogant brat! Enforcers—EXECUTE!"
BOOM!
The two Vanguard enforcers lunged forward in unison!
The shield-bearer charged along the left avenue, his heavy crested barrier glowing with green kinetic mana, while the ax-man blurred along the right, his dual executioner axes whistling through the cold air in a deadly, rotating arc!
"Not on my watch!" Marcus bellowed, slamming his boots hard into the floor and driving his dark vanadium shield straight into the charging shield-bearer’s path!
KRRR-CLANG!
The two massive shields collided with deafening kinetic force! Sparks flew across the dark chamber, but Marcus’s vanadium faceplate—reinforced by Master Kaelen’s double-welded cross-brace—didn't yield an inch. The Vanguard enforcer stumbled back two paces, his boots skidding across the slippery marble!
Timothy capitalized instantly, pulling his trigger and launching three vanadium-tipped bolts from his repeating magazine! The bolts punched clean through the ax-man’s right shoulder guard, forcing him to abort his leap and drop into a defensive roll behind a concrete pillar!
Meanwhile, Captain Vane executed a explosive forward lunge, his broadsword erupting into a ten-foot wave of roaring crimson fire aimed straight for Sabrina’s head!
Crimson Slash — Inferno Arc!
"You're slow, Vane," Sabrina said coldly.
Glacial Step — Frost Domain!
Sabrina vanished into a blur of white mist. Her silver rapier struck the flat of Vane’s flaming broadsword in mid-air, executing a brilliant parry that redirected the ten-foot flame wave straight into the vaulted ceiling, showering the chamber in falling sparks and crushed stone!
"What—?!" Vane gasped, his eyes widening as her cold frost aura instantly calcified the right sleeve of his crimson armor.
With Vane’s broadsword knocked wide and his two enforcers pinned down by Marcus and Timothy, Rian saw his vector.
SOVEREIGN’S MANTLE — ACTIVATION!
BOOM!
A dense layer of liquid dark shadow erupted from Rian's boots, wrapping around his slate-grey coat and forearms like a sleek, obsidian plate of armor!
Rian stepped into the central lane, moving directly toward Captain Vane!
Vane recovered his stance, his face twisting into a furious snarl as he saw Rian advancing without a drawn weapon. "You dare step into my reach, failure?!"
Vane reversed his broadsword, driving a devastating, Tier C- kinetic kick straight at Rian’s chest!
Rian didn't dodge. He raised his dark, shadow-clad left arm, catching Vane’s heavy iron boot mid-air!
KRRR-THUD!
The kinetic impact tore through the air, blowing the purple fog back ten feet, but Rian’s Sovereign’s Mantle absorbed forty percent of the kinetic force instantly! Rian’s body didn't shift an inch.
"Your stance is top-heavy, Vane," Rian whispered, his dark eyes glowing with a cold, violet flame. "House Craig taught you to rely on raw output. You forgot how to fight."
SOVEREIGN’S TENDRIL — QUAD EMBRACE!
WHIP-CRACK-CRACK!
From the six-meter dark pool beneath Rian's boots, four thick, pitch-black tendrils erupted from the marble floor!
Moving with terrifying speed, two tendrils wrapped tightly around Vane’s arms, pinning his flaming broadsword to his chest, while the other two tendrils coiled around his knees, locking his legs in a solid shadow vise grip!
"What is this magic?!" Vane shrieked, thrashing desperately against the two hundred units of Level 3 physical shadow force binding his frame! "Where did a Level 1 get this power?!"
Rian stepped closer, stopping inches from Vane’s face. He reached into his coat pocket with his right hand, pulling out the second dark iron Tier D+ Core Catalyst.
He crushed the catalyst between his gloved fingers, letting the refined dark-silver powder spill directly over Vane’s gold-etched chest plate, while his boot stepped squarely onto Vane’s shadow.
Living Shadow... Siphon Field — OVERLOAD!
BOOM!
A violent, pitch-black whirlpool erupted from beneath Rian’s boots!
The dark-silver catalyst powder ignited the siphoning process, turning the room into a howling void! The crimson flame aura surging from Vane’s core was violently yanked outward, turning pitch-black as it was swallowed straight into Rian’s core subspace!
> [CRITICAL EVENT: Siphoning Tier C- Vanguard Core Matrix!]

> Living Shadow EXP: 1240 / 1500 -> 1500 / 1500 (+260 EXP Overload!)

THUMP!
A bone-deep, subterranean shock wave of dark energy detonated from Rian’s chest!
The white glare of the Vanguard mana beacons flickered out, replaced by a deep, violet gloom as the Living Shadow swallowed every drop of ambient mana within a ten-meter radius! Underneath Rian's skin, the midnight-black threads expanded once more, growing thicker, denser, and weaving deeper into his muscular structure and nervous system!

Vane let out a choked, terrified gasp as his broadsword’s crimson flame died completely, its Tier C core turning grey and lifeless inside the hilt. He looked up at Rian, his face pale as a corpse, his body trembling in sheer, unadulterated horror as he saw Rian’s dark eyes burning with a deep, violet-gold radiance.
"You... you aren't human..." Vane whimpered, his voice cracking.
Across the chamber, the two remaining Vanguard enforcers saw their captain's core drained solid in under five seconds. Panicked, they dropped their weapons, turning and fleeing back into the arched corridor as fast as their iron boots could carry them!
Rian flexed his left fist, releasing the four shadow tendrils. Vane collapsed onto his knees, gasping for air as if he had just emerged from deep water.
"Tell Valen," Rian said quietly, his voice carrying the calm, double-layered resonance of an ascending Sovereign. "If he wants my head, he needs to come down to the catacombs himself."
Vane didn't utter another word. He scrambled up from the floor, stumbling backward in terror, before turning and fleeing up the arterial tunnel into the dark.
Silence returned to the Old Municipal Vault Chamber, broken only by the soft, rhythmic click of Sabrina sheathing her rapier.
She walked over to stand beside Rian, looking down at the massive, twelve-meter pool of liquid dark shadow that now stretched across the entire marble floor, covering the basalt pillars in a mantle of fluid night.
"Level 4," Sabrina whispered softly, a faint, genuine smile touching her pale lips as she looked up into his face. "Twelve meters. You're siphoning Tier C core matrices now."
"The foundation is holding," Rian replied smoothly, taking a slow, deep breath as his 600 units of newly expanded shadow mana settled peacefully into his core subspace.
Marcus and Timothy walked up, their eyes wide as they looked at the massive twelve-meter shadow pool pulsing beneath their boots.
"Rian..." Marcus stammered, running his hand over his vanadium shield. "You just drained a Tier C- Vanguard Captain in five seconds... House Craig is going to lose their minds when Vane gets back."
"Let them," Rian said flatly.
He turned his dark eyes toward the massive star-iron blast door of the Municipal Vault.
With his Living Shadow now at Level 4, his liquid dark tendrils surged twelve meters forward, seeping into the ancient locking mechanisms of the blast door. With a heavy, subterranean roar of grinding iron and shattering stone, the colossal door slowly slid open into the dark.
Inside sat three pristine, glowing Tier C spatial cores—the ancient power sources of the First Incursion.
Rian adjusted his slate-grey coat, stepping across the threshold into the vault as his shadow stretched twelve meters into the dark ahead.

The path through the deep ruins was clear. The Vanguard had fallen.
And Rian’s Living Shadow marched on.
