The mountain opened at midnight.
There was no warning.
No earthquake.
No roar.
One moment, the black cliffs stood beneath the moonlight, wrapped in mist and ancient trees.
The next—
A thin crimson line appeared across the stone.
It glowed once.
Then disappeared.
The forest went silent.
A bird launched itself from a branch somewhere above.
Then another.
Within seconds, wings beat through the darkness as every creature nearby fled deeper into the trees.
Below them, hidden beneath centuries of stone and roots—
Something moved.
The mountain split.
Not outward.
Inward.
A narrow opening formed between the cliffs, and from the darkness beneath the earth, something slowly rose.
It made no sound.
Its surface was black.
Smooth in some places.
Alive in others.
Thin lines moved beneath the metal like veins beneath skin. They pulsed once, carrying a dim red glow from one end of the structure to the other.
The shape emerged farther.
Long.
Angular.
Wrong.
Ancient roots scraped across its surface and fell away.
A final section rose from beneath the mountain.
Then everything stopped.
For several seconds, nothing happened.
The structure remained perfectly still between the trees.
Dead.
Then—
A single red light opened.
Inside the vessel, darkness retreated.
One screen flickered.
Another followed.
Then dozens.
A low mechanical voice filled the chamber.
"Resonance confirmed."
No one answered.
Several figures stood around the central display.
Their faces were hidden behind dark masks.
A crimson pulse moved across the screen.
Again.
Again.
The signal repeated.
One of the figures stepped closer.
"Location?"
The display shifted.
A map appeared.
Most of it remained incomplete.
A dark forest.
Mountain ranges.
Underground structures.
Then one name emerged at the center.
VIRELITH
The chamber went silent.
One of the masked figures slowly turned toward the person standing at the far end of the room.
The figure wore a long black coat.
Black gloves.
No mask.
But the shadows hid most of his face.
"We were told the city was dead," one of the soldiers said.
The commander watched the crimson signal.
"It was."
Another pulse crossed the screen.
The commander tilted his head slightly.
"Then something made it breathe again."
No one moved.
A soldier looked back at the display.
"Do we have confirmation of the artifact?"
"No."
The answer came immediately.
The soldier hesitated.
"Then why are we here?"
For the first time, the commander smiled.
It wasn't amusement.
It was recognition.
He stepped closer to the screen.
"Because dead cities don't scream across the continent."
The crimson signal pulsed again.
Far below the mountain—
Virelith answered.
The commander's smile disappeared.
"Prepare the descent."
Kael had stopped counting how many lights had awakened.
Every time they entered another corridor, another section of the city seemed to remember itself.
A line of emerald light ran beneath the floor beside them.
It disappeared beneath a wall.
A moment later, the symbols carved into the stone ignited.
Xyren followed the light with his eyes.
"I don't think I'll ever get used to that."
Elaris glanced at him.
"You said that twenty minutes ago."
"I've discovered several new things since then."
Kael looked back.
"Such as?"
Xyren raised one finger.
"That those walls aren't walls."
Kael stopped.
"What?"
Xyren pointed behind him.
Everyone looked.
The stone wall stood exactly where it had been.
Silent.
Motionless.
Then—
A section of it shifted.
Xyren stepped back.
The entire wall slowly folded inward.
Layers of stone separated without cracking, revealing a narrow passage behind it.
Kael stared.
Xyren folded his arms.
"See?"
Elaris looked at AURIXA.
"Did you know that was there?"
AURIXA stared at the passage.
"No."
Xyren turned toward her.
"That is somehow less reassuring."
AURIXA walked closer.
Thin lights appeared inside the newly opened corridor.
One.
Then another.
"Virelith is restoring systems faster than expected."
Kael looked at Stormfang.
The crimson line beneath the blade pulsed once.
"Is that bad?"
"I don't know."
Kael gave her a look.
AURIXA glanced back at him.
"I am beginning to dislike that answer as well."
Xyren smiled.
"Welcome to the club."
They entered the passage.
The corridor curved downward.
Roots covered one side of the wall while the other was lined with smooth metallic panels. Small circular symbols glowed beneath the surface.
Elaris slowed.
"Listen."
Kael stopped.
At first, he heard nothing.
Then—
A faint hum.
Not from the walls.
Not from the floor.
Something deeper.
Like a thousand distant voices speaking behind closed doors.
Xyren lifted his scanner.
The screen immediately activated.
He frowned.
"I didn't turn that on."
Kael looked over his shoulder.
A stream of symbols flashed across the display.
Xyren tapped the side of the device.
"What are you doing?"
"Nothing."
The screen changed.
UNKNOWN NETWORK DETECTED
Xyren's expression tightened.
Elaris leaned closer.
"Can it connect?"
"To what?"
The scanner beeped.
Another line appeared.
CONNECTION REQUEST—
The screen went black.
Xyren stared at it.
Then pressed the power button.
Nothing.
He turned it over.
Tapped the back.
Still nothing.
Kael watched him.
"City interference?"
Xyren exhaled.
"Probably."
AURIXA looked at the scanner.
Then at Xyren.
"Probably."
Kael noticed the pause before she said it.
Before he could ask—
Something moved at the end of the corridor.
Everyone froze.
Kael's hand went to Stormfang.
Elaris lifted one hand.
Roots beneath the floor shivered.
Xyren slowly raised his scanner.
The darkness ahead remained empty.
Then—
Tick.
A small stone rolled across the floor.
Kael waited.
Nothing followed.
Xyren lowered the scanner.
"Falling debris."
Elaris didn't move.
"No."
Kael looked at her.
"What?"
She stared into the darkness.
"I heard something before that."
"What?"
Elaris shook her head.
"I don't know."
AURIXA turned toward the corridor behind them.
For one second, her expression changed.
Then it was gone.
"Keep moving."
Kael frowned.
But followed.
Far beneath another section of Virelith, darkness opened.
A black-gloved hand pressed against an ancient wall.
Nothing happened.
The masked figure standing beside the commander shifted impatiently.
"Are you certain?"
The commander didn't answer.
Instead, he removed a small object from inside his coat.
It was no larger than his palm.
Black.
Thin.
Shaped like a broken piece of metal.
Except metal did not pulse.
This did.
A dark crimson light travelled through its center.
The commander pressed it against the wall.
For several seconds—
Nothing.
Then the roots surrounding the stone moved.
One by one, they pulled away.
The soldier took a step backward.
The wall opened.
A narrow tunnel waited beyond it.
Dust covered the floor.
Ancient symbols disappeared into darkness.
One of the soldiers looked at the commander.
"That route isn't in the archive."
"Exactly."
The commander stepped inside.
The others followed.
The wall closed behind them.
For several minutes, only their footsteps filled the tunnel.
Then every light went out.
One soldier stopped.
"Commander?"
Darkness swallowed the corridor.
A whisper moved through the tunnel.
Not human.
Not mechanical.
Something between both.
"Unauthorized presence."
Weapons activated.
Thin blue lines illuminated the darkness.
The soldiers spread apart.
"Identify yourself."
No answer.
The commander remained perfectly still.
Then—
The lights returned.
The tunnel was empty.
One soldier exhaled.
"False activation."
Something touched the side of his mask.
He froze.
Slowly—
He turned.
A single root hung from the ceiling.
It hadn't been there before.
The root curled.
Not randomly.
Toward him.
The soldier raised his weapon.
The commander caught his arm.
"No."
The soldier looked at him.
"It moved."
"I know."
The commander stepped closer.
The root remained still.
Then a thin line of green light passed through it.
The commander's eyes narrowed.
"It's waking faster than predicted."
The root suddenly withdrew into the ceiling.
The tunnel went silent again.
The commander looked forward.
"Move."
Kael stepped out onto another platform and stopped.
The city stretched below.
A transport system raced along the living rails in the distance.
Lights burned inside towers that had been dark for centuries.
Somewhere far below, a mechanical arm emerged from beneath a collapsed structure and began moving stones aside.
Another machine climbed across a wall on six metallic legs.
It paused.
Turned its head toward Kael.
Then continued working.
Xyren stared.
"Did that thing just ignore us?"
AURIXA walked past him.
"It has work to do."
Xyren followed.
"What exactly?"
She looked toward the ruined city.
"Whatever it remembers."
Kael remained near the edge.
Stormfang hummed softly.
The city felt different now.
Not awake.
Not completely.
More like someone standing on the edge of consciousness.
Every few seconds, another light appeared somewhere in the distance.
Every few seconds, something moved.
A door opened.
A machine activated.
A vine climbed across stone.
Then—
Stormfang stopped humming.
Kael looked down.
The crimson line beneath the blade had gone still.
His hand tightened around the hilt.
"Elaris."
She turned.
"What?"
"Do you feel that?"
Her expression changed.
She closed her eyes.
For a moment, nothing happened.
Then the leaves growing along the nearby wall folded shut.
Elaris opened her eyes.
Kael saw it immediately.
"What is it?"
"I don't know."
Xyren looked between them.
"Why does everyone keep saying that?"
No one answered.
A sound echoed across the city.
KRRRNNNNN—
The lights around them flickered.
Once.
Twice.
Then half the city went dark.
Kael pulled Stormfang free.
Blue and crimson lightning crawled along the blade.
Elaris's roots pushed through the stone.
Xyren's scanner activated again.
"I swear I didn't—"
The screen filled with static.
Then went completely blank.
AURIXA stopped.
Her head slowly turned toward a corridor behind them.
The expression on her face made Kael's stomach tighten.
"What is it?"
She didn't answer.
One of the lights above them died.
Then another.
Darkness spread down the corridor.
Click.
A third light went out.
Kael stepped forward.
"AURIXA."
Her eyes remained fixed on the darkness.
"That's impossible."
Kael raised Stormfang.
"What?"
For several seconds, she said nothing.
Then her voice came quietly.
Almost like she didn't want the city to hear her.
"Someone is inside Virelith."
Far below them—
In a tunnel that should not have existed—
the commander stopped walking.
A wall stood at the end of the passage.
Ancient.
Sealed.
Waiting.
The black object in his hand pulsed.
Once.
The wall answered.
A crimson line appeared across the stone.
The commander smiled.
Behind him, one of the soldiers spoke.
"Commander?"
He placed his hand against the opening wall.
"Now," he said.
The darkness beyond began to breathe.
"We find the Heart."
