The underground city seemed to hold its breath.
The soft melody of ancient bells faded beneath a deep vibration that spread through the cavern like distant thunder. Silver rivers flowing beneath the crystal streets rippled violently, their tranquil glow breaking into chaotic waves that reflected across towering buildings and elegant bridges. High above, the crack in reality trembled continuously while fragments of space peeled away from its edges like shattered pieces of glass, disappearing into the endless darkness beyond.
For the first time since the crack had appeared...
The danger wasn't coming from the Door.
It was coming from something beyond it.
The smiling figure remained perfectly still.
Its calm expression had vanished completely.
The warmth that had always accompanied its voice disappeared, replaced by quiet concentration. The darkness surrounding its body tightened like a living cloak while ancient symbols drifted around its feet before dissolving into the void behind it.
Kael noticed something immediately.
The smiling figure wasn't looking toward the underground city anymore.
It wasn't watching the Sleeper.
It wasn't watching the First Son.
It wasn't even watching him.
It was staring into the darkness behind itself.
Watching something approach.
The realization sent a chill through the observation platform.
The First Son slowly stepped forward until he stood at the very edge of the platform overlooking the abyss. Brilliant golden light surrounded him, illuminating every crack in the ancient stone beneath his feet. His expression had become completely serious, yet there was no fear in his eyes.
Only resolve.
"How long?"
The question echoed through the underground city.
The smiling figure answered without turning around.
"Not long."
Silence followed.
The stranger adjusted the ancient book beneath his arm before quietly walking beside the First Son. Thousands of glowing runes emerged from the pages and began circling above the city like silver constellations. Each rune cast intricate reflections across nearby towers, revealing carvings so detailed that Kael could suddenly distinguish scenes etched into the stone.
Children chasing birds.
Families gathered beneath flowering trees.
Musicians playing beside crystal fountains.
Scholars teaching beneath enormous silver bells.
The prison had preserved everything.
Not merely buildings.
Memories.
The stranger looked toward those carvings with distant eyes.
"I spent decades recording every family that lived here."
His voice carried quiet pride.
"I refused to let history forget them."
Kael followed his gaze.
The walls surrounding the nearby plaza weren't decorated with random patterns.
They were names.
Thousands upon thousands of names covered the silver stone in elegant ancient script, stretching across walls, pillars, and arches until the entire district resembled a library carved directly into the city itself.
Every citizen...
Remembered.
The realization settled deeply within him.
This civilization hadn't feared being forgotten.
They had prepared for it.
The Sleeper slowly descended the wide marble steps beneath its silver throne. Each step it took caused ancient light to spread through nearby streets, awakening long-dormant mechanisms hidden beneath the city. Massive circular platforms emerged from beneath plazas while towering pillars slowly rose between districts. Bridges shifted position with the slow precision of ancient machines before locking into entirely new configurations.
The city was transforming.
Not collapsing.
Preparing.
General Caelan stared across the changing landscape.
"This place..."
He struggled to find the words.
"...it's becoming a fortress."
The Sleeper gently shook its head.
"It always was."
A deep rumble interrupted the conversation.
This time the sound didn't come from beneath the city.
It came from beyond the crack.
The darkness rippled.
Not outward.
Inward.
Like an ocean disturbed by something unimaginably large swimming beneath its surface.
Then...
A single silver star appeared.
Everyone froze.
The star drifted through the darkness behind the smiling figure before disappearing.
Another followed.
Then another.
Soon hundreds of tiny silver lights floated through the endless void, surrounding the smiling figure without touching it.
Kael frowned.
"They're beautiful."
The smiling figure closed its eyes.
"No."
Its voice had grown noticeably quieter.
"They're running."
The sentence transformed the scene instantly.
Kael looked closer.
The stars weren't stars.
They were fragments.
Broken worlds.
Each tiny light contained mountains.
Oceans.
Cities.
Entire civilizations reduced to glowing embers drifting endlessly through the void.
The scale defied imagination.
Lyra slowly stepped backward.
"Those are..."
The stranger answered softly.
"Worlds."
No one spoke again.
Hundreds of worlds floated silently through the darkness beyond reality like forgotten ashes carried by an invisible current.
The smiling figure watched them pass with obvious sorrow.
"They always come first."
The First Son's golden eyes narrowed.
"It consumed them already."
A simple nod answered him.
Kael's heartbeat quickened.
Whatever approached...
Had already destroyed worlds.
Not one.
Hundreds.
The black mark beneath his skin suddenly pulsed.
A new memory surfaced.
This one felt older than every previous vision.
He stood alone upon a cliff overlooking an endless sea beneath a sky filled with unfamiliar stars. The wind carried the scent of salt through the air while silver grass bent gently across rolling hills stretching toward the horizon. It wasn't the ancient city.
It wasn't the prison.
It wasn't even the same world.
The fourth brother stood nearby.
He looked younger.
Quieter.
Gone was the endless laughter Kael had grown accustomed to seeing.
Instead, he stared toward the night sky.
"So many."
Kael's ancient self stepped beside him.
"So many what?"
The fourth brother slowly raised one hand toward the heavens.
"So many worlds."
His voice sounded strangely hollow.
"I thought ours was the only one."
The memory-version of Kael followed his gaze.
Among countless stars...
Several were disappearing.
Not exploding.
Simply...
Going out.
One after another.
Like candles extinguished by an unseen hand.
The fourth brother whispered something that made Kael's blood run cold.
"It's getting closer."
The memory ended instantly.
Reality crashed back.
Kael inhaled sharply.
His eyes shot toward the drifting fragments beyond the crack.
The stars.
The dying worlds.
They hadn't been random.
The fourth brother had seen them before.
Long before the Door.
Long before the prison.
Long before the war.
Which meant...
The catastrophe hadn't started with them.
It had been coming all along.
The smiling figure slowly looked toward Kael.
A sad smile returned to its face.
"You remember now."
Kael swallowed.
"The Door..."
The smiling figure nodded.
"It was never opened to let something out."
Silence settled over the underground city.
Even the bells stopped ringing.
The smiling figure finally finished the sentence.
"It was built..."
It looked toward the endless darkness behind it.
"...to keep something from coming in."
The underground city shook violently.
Far beyond the crack...
Two enormous eyes slowly opened within the darkness.
Unlike the golden eye...
These eyes had no color.
No light.
No emotion.
They were completely black.
And they were looking directly at the prison.
