The night after the duel, Leonhart couldn't shake the strange restlessness gnawing at him. He tried to meditate, to let his mana flow and settle his thoughts, but the air itself felt… off. It wasn't the usual hum of Atherion's world essence—it was jagged, fragmented, like a melody played on broken strings.
Following the sensation, he slipped quietly from his dorm and crossed the academy courtyard. The moon was full, yet shadows pooled unnaturally at the base of the eastern wall. His instincts screamed at him to leave it alone, but Leonhart had never been one to ignore the whispers of the unknown.
When he pressed his hand against the cold stone, the wall shimmered. A faint glyph pulsed to life, so ancient that even his knowledge as a former king struggled to identify it. With a grinding rumble, part of the wall shifted, revealing a narrow passage sloping downward into darkness.
"A hidden structure beneath the academy?" Leonhart muttered, narrowing his eyes. "Or perhaps something older."
He descended carefully. The deeper he went, the colder the air grew, the faint scent of iron and something acrid filling his lungs. After several minutes, the narrow passage opened into a vast underground chamber. What lay before him was unmistakable: a labyrinth. The walls glistened as though alive, shifting faintly under torchlight, and an oppressive aura leaked from its depths.
Leonhart's lips curved into a thin smile. So this is the source of the disturbance.
But he wasn't alone.
Footsteps echoed from another corridor. He quickly concealed his presence, merging his shadow into the wall. A group of hooded figures emerged, their voices hushed but urgent.
"The seal weakens," one said in a gravelly tone.
"Good. The offering is nearly ready," another replied. "When the moon turns crimson, the Devourer will awaken fully, and the world will tremble once more."
Leonhart's eyes narrowed. A sect. Of course. Wherever there's forbidden power, there are always lunatics ready to worship it.
The hooded men carried strange artifacts—bloodstained daggers, a twisted idol carved from obsidian, and scrolls covered in symbols that pulsed faintly with malice. They moved deeper into the labyrinth, chanting softly in a tongue that prickled against Leonhart's skin.
He considered revealing himself, but instinct told him otherwise. Instead, he followed silently, noting every path they took. The labyrinth was a living puzzle, corridors shifting subtly when unwatched, but the sect members walked with certainty—as though guided by something unseen.
At the heart of the labyrinth, they stopped before a massive gate covered in runes. The leader raised his hands, chanting, and the runes flared red. A pulse of energy rolled outward, slamming against Leonhart's chest. For a brief moment, the shadows around him stirred violently, resonating with the gate's seal.
He gritted his teeth. Damn it… they can sense me if I stay any longer.
The leader suddenly stiffened, his hood tilting slightly. "Did you feel that?"
One of the followers hesitated. "A… presence. Watching."
The leader's voice turned sharp. "Search the corridors. No one must know of this place."
Leonhart slipped away just as the sect members fanned out. His heart pounded—not from fear, but from exhilaration. He had found something far bigger than he expected: a labyrinth beneath Arclight, a sect preparing a ritual, and a gate that pulsed with a power dangerously similar to his own.
Back at the academy surface, the night seemed calm again, but Leonhart knew better. He gazed at the moon, whispering to himself, "So… fate insists on dragging me back into the shadows."
The king reborn clenched his fist. "Fine. Let's see what you're hiding, labyrinth."
Back at the academy surface, Leonhart's steps faltered as he reached the courtyard again. The cool air of the night should have calmed him, yet his pulse refused to slow. The labyrinth's aura still clung to him, an invisible weight pressing down like chains. He closed his eyes, exhaled, and muttered to himself, "No… I can't stop here. Not when I've already stepped into their shadows."
He returned the following night, prepared. A dagger strapped at his thigh, mana threads woven subtly around his wrist in case of emergencies. The eastern wall awaited him, unchanged, though the glyph shimmered faintly, almost beckoning. With a steady breath, he pressed his palm against it again, and the hidden passage groaned open.
The labyrinth swallowed him whole.
This time, the corridors felt alive in ways they hadn't before. The stone under his fingertips pulsed faintly, like veins under skin. Every so often, the walls shifted with a grinding noise, corridors bending into new shapes. Leonhart paused, studying the subtle patterns. It reacts to mana… and to intent. This place doesn't want intruders wandering freely.
Deeper inside, he encountered the first obstacle: a hallway lined with statues of armored knights. Their helmets were lowered, swords resting tip-first against the floor. At first, they seemed like harmless decorations. But when Leonhart stepped forward, one statue's head twitched. Then another. The grinding of stone echoed as they turned toward him, hollow eyes glowing crimson.
"Guardians," Leonhart muttered, drawing his cracked training blade. "Naturally."
The first knight lunged, its stone sword cleaving downward with surprising force. Leonhart sidestepped, shadows curling at his feet to enhance his speed. He countered with a precise slash to its neck, shattering stone into shards. Yet as soon as one fell, two more advanced.
Minutes bled into a harsh rhythm of parries and dodges. The air filled with dust and fragments of stone, Leonhart weaving through the guardians with efficiency born of countless wars. Finally, he released a fraction of his power—a pulse of shadow that rippled across the corridor, extinguishing the crimson light in their eyes. The guardians froze, crumbling into lifeless rubble.
Panting lightly, Leonhart touched his chest. I can't keep using that. Not here. If the sect is nearby, they'll sense it.
He pressed forward.
Further into the labyrinth, the corridors opened into a wide chamber. At its center lay a strange pedestal, upon which floated a shard of black crystal, faintly humming. The moment his gaze fell upon it, his shadows stirred unbidden, reaching toward the shard like vines seeking sunlight.
Leonhart clenched his jaw. What is this…?
He stepped closer, but before he could touch the shard, a low growl reverberated through the chamber. From the darkness beyond the pedestal, a figure emerged—not human, not beast, but something caught in between. Its skin was stretched thin over sharp bones, its eyes glowing with the same crimson fire as the guardians. Chains clinked as it dragged itself forward, bound yet still terrifyingly alive.
"A failed summoning…" Leonhart murmured, his grip tightening on his blade. "The sect left you here to rot."
The creature roared, its voice a mix of agony and rage, and lunged.
Leonhart steadied his stance, a cold smile tugging at his lips. "Fine. Let's see what secrets you're hiding."
The beast lunged, claws scraping sparks from stone as it crashed toward Leonhart. He pivoted, his cracked blade intercepting the strike, but the sheer weight behind it drove him back several steps. Dust plumed, the chamber shuddering with each blow.
The creature's breath reeked of decay, its chains rattling violently as though they moved of their own accord. Leonhart's gaze sharpened. This thing isn't just a monster—it's bound by something. A failed ritual, or perhaps a sentinel for intruders.
The beast swung again. Leonhart ducked low, shadows curling around his legs to propel him forward. His blade slashed across its chest, leaving a faint crack glowing with black light. The monster shrieked, staggering, but instead of falling, the glow spread, its body thrumming with unstable mana.
"Unfinished work," Leonhart muttered grimly. "Which means—"
Before he could finish the thought, the air trembled. Faint chanting echoed through the corridors ahead. Multiple voices, rhythmic, reverent, and utterly unnatural. The beast froze, then howled, its chains tightening and dragging it backward into the darkness.
Leonhart steadied his breath. They're close.
He pressed forward, blade ready, following the sound of chanting. The labyrinth shifted subtly again, guiding him—or perhaps herding him—toward the source. Finally, he reached a vast cavern lit by crimson torches.
There, dozens of hooded figures knelt in concentric circles around a bloodstained altar. At the center stood their leader, taller than the rest, his hood adorned with silver embroidery. Before him lay a corpse, its chest carved open, heart missing. Dark ichor stained the stone.
"The vessel nears completion," the leader intoned, his voice echoing with unnatural resonance. "Soon, the Devourer shall be free. Soon, Atherion will remember the glory of shadows."
Leonhart's hands curled into fists. The words crawled across his skin like fire. That name—Devourer—wasn't new. He had faced them once, long ago, creatures that thrived on destruction, the very same monsters that once threatened to annihilate entire kingdoms. If this sect was truly trying to unseal one…
No. I can't allow this.
He crept closer, pressing himself against the shadows of a pillar. The chanting grew louder, the air vibrating with malignant energy. Runes on the cavern floor lit up, forming a circle that pulsed like a heartbeat.
But then, one of the hooded figures stilled. Slowly, they lifted their head, gaze sweeping the cavern. Their voice cut through the chants. "Someone watches."
The leader's head turned sharply. A wave of killing intent spread across the cavern, and suddenly the torches flared brighter.
Leonhart hissed softly. Damn it. They sensed me.
Several cultists rose, daggers drawn, their crimson eyes gleaming under the hoods. They began moving toward the shadows where Leonhart hid.
He exhaled slowly, fingers tightening on his blade. "So much for observing quietly."
As the first cultist lunged into the darkness, Leonhart stepped forward, shadows erupting around him like a cloak. His voice, calm and razor-sharp, cut through the cavern:
"You dare invoke the Devourers?"
The cultists froze at the weight of his presence.
Leonhart's eyes burned with dark light as he raised his blade. "Then you'll face the king they once feared."
The cultists surged forward, blades glinting under the crimson torchlight. Leonhart moved like a shadow, his cracked sword intercepting the first strike. Steel rang against steel, sparks scattering, and in the same motion, he twisted, driving his elbow into the cultist's throat. The man collapsed with a strangled gasp.
Another came from behind. Leonhart didn't turn—his shadow rose up like a living spear, impaling the hooded figure clean through the chest. Gasps rippled among the followers. For a heartbeat, silence reigned, broken only by the hiss of the flames.
The leader's voice boomed across the cavern. "Do not falter! The Devourer awaits! Spill his blood as an offering!"
A dozen voices howled in unison, their chants twisting into guttural screams. The rune-circle on the floor pulsed violently, crimson veins spreading outward like roots.
Leonhart gritted his teeth. He couldn't allow the ritual to continue. He cut down another follower, then another, his movements efficient, merciless, but measured. He couldn't reveal his full strength—not yet.
But as the last cultist fell, Leonhart froze.
The pedestal at the cavern's center cracked. From within, a faint glow spread, revealing a blackened artifact—an orb veined with shifting silver patterns. Its surface rippled like liquid, and the oppressive aura it radiated was almost suffocating. His shadows quivered, reacting to it instinctively, drawn toward it like moths to flame.
Leonhart's eyes narrowed. "What in the hells…"
The cult leader stepped toward the orb, his hood falling back to reveal a face marked with runes carved into the skin itself. His eyes gleamed with manic devotion. "The Fragment of the Devourer," he whispered reverently. "Our key… our god's rebirth."
The runes on the gate behind the altar flared awake. It was massive, jagged stone doors bound with chains thicker than trees, every link glowing faintly red. The entire chamber shook as if something vast pressed from the other side, desperate to break free.
A deep growl reverberated from behind the gate, primal and hungry. Dust rained from the ceiling, torches flickering under the weight of its malice.
Leonhart's breath caught, a strange, sharp pull gripping his chest. He'd fought Devourers before in his old life. He'd killed them. But this presence… it felt older, deeper, as though it knew him.
The leader raised the orb high, his voice breaking with fervor. "Witness! The chains weaken! Soon, the Devourer shall walk again, and the world will kneel!"
"Over my dead body," Leonhart muttered. He surged forward, shadows exploding outward to snatch the orb from the cult leader's grasp.
The man shrieked, resisting, but Leonhart's strength was absolute. The orb slammed into his palm, searing cold running up his arm. For a heartbeat, the world tilted—the shadows inside him writhed violently, resonating with the fragment.
And then, silence.
The rune-circle flickered out. The cultists still conscious screamed in denial, falling to their knees as if the very ground betrayed them. The gate groaned, the chains tightening once more, suppressing whatever had stirred within.
Leonhart stared at the orb in his hand, chest rising and falling sharply. The fragment pulsed faintly, as though it recognized him.
"Damn it…" he whispered, slipping it into his cloak. "This is going to be a problem."
He turned to leave, but not before giving the leader—still crawling weakly on the floor—a final glance. His voice was calm, deadly.
"Tell your master this: the king of shadows doesn't bow to anyone. Not gods, not monsters, and certainly not cults."
With that, Leonhart melted into the labyrinth's shifting halls, the fragment's weight heavy in his pocket, and the ominous promise of the gate echoing in his mind.
The Devourer wasn't free yet. But it was awake.
