"Civilizations don't vanish. They rot from the inside, and the bones remember."
The light from the ancient tablet faded, leaving only the soft glow of scattered embers flickering across the museum's grand hall.
Kael exhaled, lowering his hand. His palm still tingled faintly — not pain, but awareness.
Something inside him was listening.
Yuna touched his arm carefully. "You shouldn't have done that."
"Too late," he said, scanning the room. "We need to move. Whatever powered this thing… it's still active somewhere."
Min-Jae looked uneasy, clutching his makeshift weapon — a rusted iron pipe. "Kael, I don't like this. The air feels… wrong."
"It's alive," Kael muttered. "Feel it?"
And indeed, the museum seemed to breathe. The faint hum from the walls vibrated softly in their bones, and the shadows seemed to move when no one was looking.
They followed a cracked marble staircase downward. The emergency lights still flickered — dim blue strips casting their faces in ghostly color.
Lower Level – Restricted Archives
The doors here weren't glass or wood. They were metal. Reinforced, sealed with symbols no one could read.
Min squatted, inspecting a small terminal beside the door. "Looks like biometric locks. But it's ancient tech — maybe I can bypass it."
Kael crouched beside him. "You have five minutes."
As Min worked, Yuna scanned the hall behind them. The silence pressed harder now, dense with something unseen.
That's when she noticed it — faint markings across the floor. Bare footprints.
Fresh.
"Kael," she whispered. "We're not alone."
Before he could reply, the lock clicked. The door hissed open.
A wave of air rushed out — warm, metallic, and laced with the faint smell of ozone.
Min grinned nervously. "Got it—"
A gunshot cracked through the hall.
The bullet missed Min's head by inches, ricocheting off the metal frame.
"DOWN!" Kael shouted, pulling him to the ground.
More shots followed — three, four, echoing from the dark ahead. Sparks danced along the floor as rounds slammed into the walls.
Yuna dragged Min behind a pillar, her heart racing. "Who the hell is shooting?!"
Kael leaned out, eyes sharp. Through the smoke, he saw movement — figures emerging from the shadows.
Five of them.
Armored, armed with scavenged weapons. Their leader — tall, scarred, and wearing a cracked ballistic mask — carried something that made Kael's breath catch.
A core.
Black. Pulsing. Embedded into his chest.
The man's voice was deep, distorted through the mask.
"So the rats made it to my nest. Didn't think anyone else was stupid enough to come down here."
Kael didn't answer. He just took in the man's stance, his weapon, the unnatural flicker of veins around the core embedded in his skin.
Yuna whispered, "What… is he?"
Kael's expression hardened. "Corrupted."
The man laughed, a sound that grated like metal. "Corrupted? No. Evolved. You're looking at humanity's next step."
He gestured toward his chest, the black core pulsing with each heartbeat. "It gives me strength. Vision. Hunger. You wouldn't understand."
Kael stepped forward slightly. "You killed for it."
"Of course I did," the man growled. "We all kill for something. Food. Water. Hope." He paused, eyes narrowing. "But you… you reek of something different."
The black veins around his neck flared. His eyes glowed faintly — red.
"Tell me, stranger," he said slowly, "what did you see when you touched the artifact upstairs?"
Kael froze.
"How do you know about that?"
The man chuckled darkly. "Because I touched it too. Before it rejected me."
His voice cracked, warped — and then his body began to shift. Bones groaned, muscles swelled. His skin darkened as the veins pulsed black like molten tar.
Yuna gasped. "Kael—he's changing!"
Kael didn't hesitate. "Min! Flashbang!"
Min fumbled in his pack, pulling out a single improvised grenade they'd salvaged days ago. Kael yanked the pin and threw it.
Light exploded through the hall.
The creature screamed, clutching its face, and Kael lunged. Knife drawn, he aimed for the throat — but his blade met iron-hard skin.
The creature laughed through the pain. "You think steel can cut evolution?"
It swung — fast. Too fast. Kael barely ducked, the blow shattering the pillar behind him. Debris rained down as he rolled to the side.
Yuna threw her hands forward instinctively — light flaring from her palms. A golden barrier snapped into existence, stopping the creature's next strike just inches from Min.
Her breath hitched, sweat beading on her forehead. "I can't hold it long!"
Kael scrambled to his feet, mind racing.
Black core… unstable… overloading… there has to be a weakness.
Then he saw it — the veins around the core. They pulsed in rhythm with the creature's breathing.
He grabbed a shard of rebar from the debris and shouted, "Min! Distract him!"
Min blinked. "How?!"
Kael snarled, "Just—make—noise!"
Min picked up a chunk of glass and threw it at the creature's head. "HEY! Over here, you overcooked lizard!"
The creature turned with a roar, and in that instant Kael moved. He darted forward, every muscle screaming in protest, and jammed the rebar directly into the core's pulse point.
The scream that followed wasn't human.
The light in the creature's chest flared violently — black turning red, red to white — before imploding in a wave of shock energy that sent everyone flying.
The world went silent.
When Kael opened his eyes, everything hurt. Dust filled the air, and the hall was half-collapsed. He groaned, pushing himself up.
Yuna was kneeling nearby, coughing but alive. Min was unconscious, but breathing.
And the creature… was gone.
Only a black stain remained, burned into the floor.
Yuna looked around in disbelief. "What… happened to him?"
Kael stared at the mark. "The core consumed him. Couldn't stabilize."
He reached into the residue — and felt something solid. A shard.
Small. Jagged. Still warm.
He pocketed it quietly. "Let's move. Before this place buries us."
They reached a side chamber before the ceiling gave way entirely. Inside, sealed behind a cracked glass display, was a set of old relics — untouched.
A bronze cup.
A rusted spear.
And a single pendant engraved with a spiral symbol.
Kael's eyes locked on the cup. It was identical to the one he'd found before — the wine-glass-shaped artifact that filled once every six months.
Only this one was full.
He reached out — and before Yuna could stop him, the liquid shimmered and leapt toward his hand, seeping into his skin.
A flash of pain tore through him, and visions struck — fire, blood, a dragon's eye staring straight into his soul.
And then — silence.
Kael collapsed to one knee, gasping. Yuna caught him. "Kael! Talk to me!"
He looked up slowly, eyes glowing faintly silver for a moment. Then the light faded.
His voice was hoarse. "It showed me something."
Yuna frowned. "What?"
Kael's hand trembled as he whispered, "The end of this city. The dragon… and me. Standing in its path."
Her breath hitched. "And the others?"
Kael looked away. "Dead. All of them."
The silence that followed was heavier than any roar.
Yuna swallowed hard, her voice trembling. "Then what do we do?"
Kael rose slowly, his expression unreadable. "We change the ending."

The black core doesn't just enhance — it rewrites. It turns men into creatures of instinct. The balance system described in the tablet wasn't designed for humanity. We were trespassers in a system we don't understand.
The bronze chalice is more than an artifact — it's a recorder. It shows what's inevitable, not what's impossible.
But if I've already seen my death… maybe that means I have time to change it.
For now, Yuna trusts me. Min fears me. Both are correct.
