The underground city was silent.

Noah Vey stood inside a narrow metal corridor while red lights flashed above him.

He could hear machines moving somewhere behind the walls.

Thousands of them.

Perhaps millions.

He had no idea where he was.

He only knew one thing.

The girl named Lyra had brought him here because people from the future were hunting him.

And according to her, he was responsible for the end of humanity.

Noah wanted to laugh.

It had to be a joke.

He was seventeen years old.

He had never built a machine.

He had never traveled through time.

He had never even left New Avalon.

Yet somehow, the people of the future believed he would destroy the world.

Lyra continued walking.

“Stay close.”

Noah followed her.

“Where are we going?”

“To the Archive.”

“What is the Archive?”

“The place where your future begins.”

Noah stopped.

Lyra turned around.

“What?”

“You keep saying things like that.”

“Like what?”

“Your future. Your city. Your world.”

Noah pointed toward the dark corridor.

“I don’t understand any of this.”

Lyra stared at him for several seconds.

Then she sighed.

“You’re right.”

She walked toward a metal door.

“This is going to be difficult.”

The door opened.

Noah entered.

His mouth fell open.

The room was enormous.

Thousands of glowing screens covered the walls.

Holographic maps floated in the air.

Strange machines stood in glass containers.

At the center of the room was a giant circular structure.

It looked like a machine.

But it was unlike anything Noah had ever seen.

It had no visible wires.

No buttons.

No control panel.

Only a large black sphere surrounded by rings of blue light.

Noah stepped closer.

“What is that?”

Lyra looked at it.

“The Future Engine.”

Noah stared.

“The machine that predicts the future?”

“Yes.”

“Who built it?”

Lyra remained silent.

Noah turned toward her.

“Who?”

Lyra finally answered.

“Yourself.”

Noah laughed.

It was the only thing he could do.

“That’s impossible.”

“You haven’t built it yet.”

“Exactly.”

“Not in your time.”

Noah looked at the machine again.

Lyra walked toward the center of the room.

“The Future Engine was activated in 2219.”

Noah looked confused.

“That’s forty-five years from now.”

“Correct.”

“Who built it?”

Lyra looked directly at him.

“You did.”

Noah shook his head.

“No.”

“Yes.”

“I’ll be sixty-two.”

“Sixty-three.”

Noah stared at her.

Lyra continued.

“Your older self became the greatest scientist in human history.”

Noah slowly walked backward.

“No.”

“You created the first machine capable of looking beyond the present.”

“No.”

“You discovered that time isn’t a straight line.”

Noah’s breathing became faster.

“No.”

“You discovered that the future already exists.”

“Stop.”

Lyra stopped speaking.

Noah looked at the machine.

The black sphere was slowly rotating.

“What happened to me?”

Lyra’s expression changed.

“That’s the part nobody understands.”

She touched a control panel.

The room went dark.

A holographic image appeared in front of them.

Noah saw a man.

He was older.

Much older.

His hair was gray.

His face was thinner.

But there was no doubt.

It was Noah.

Noah Vey.

The older version of himself stood inside a massive laboratory.

Behind him was a machine identical to the Future Engine.

Noah stared at the hologram.

“That’s me.”

Lyra nodded.

The recording began.

The older Noah spoke.

“If you are watching this message, then the experiment has failed.”

Noah felt a strange sensation in his chest.

The older version of himself continued.

“I spent forty years searching for the perfect future.”

Images appeared behind him.

Wars.

Destroyed cities.

Burning oceans.

Empty planets.

Then everything disappeared.

A new image appeared.

The floating city.

New Avalon.

Beautiful.

Perfect.

Noah watched in silence.

His older self spoke again.

“I believed humanity could survive if we moved civilization beyond time.”

The hologram changed.

The enormous city rose into the sky.

“New Avalon was the first Temporal City.”

Noah looked at Lyra.

“Temporal City?”

“A city that exists outside normal time.”

Noah turned back toward the hologram.

His older self continued.

“At first, I thought I had succeeded.”

The screen suddenly turned red.

Warnings appeared.

TEMPORAL COLLISION DETECTED.

FUTURE INSTABILITY DETECTED.

CAUSALITY FAILURE.

Noah’s face went pale.

His older self looked terrified.

“I was wrong.”

The hologram showed the city shaking.

Buildings disappeared.

People vanished.

Time itself seemed to break apart.

“I discovered that the Future Engine was not predicting the future.”

Noah whispered.

“What was it doing?”

Lyra answered.

“Creating it.”

Noah looked at her.

The older Noah continued speaking.

“Every future the machine showed us became real.”

Noah’s eyes widened.

“The machine wasn’t predicting possible futures.”

The older Noah looked directly at the camera.

“It was choosing them.”

The recording stopped.

Silence filled the Archive.

Noah looked at Lyra.

“Why?”

Lyra shook her head.

“We don’t know.”

“Then why does everyone think I’m going to destroy the world?”

“Because your older self made one final decision.”

“What decision?”

Lyra walked toward another screen.

She activated it.

A massive map appeared.

The Earth was covered with red lines.

Then Noah saw something that made his heart stop.

A single line connected the year 2199 to 2174.

His year.

His arrival in the future.

Noah stared.

“What is that?”

“Your timeline.”

“Why is it connected?”

“Because your older self sent you here.”

Noah felt dizzy.

“Sent me?”

Lyra nodded.

“Your older self knew the Future Engine would eventually destroy reality.”

Noah looked at the screen.

“Then why didn’t he destroy it?”

“He tried.”

“What happened?”

Lyra’s voice became quieter.

“He couldn’t.”

“Why?”

“Because the machine had already predicted his decision.”

Noah stared at her.

Lyra continued.

“Every attempt to destroy the Future Engine created another future where the machine survived.”

Noah looked at the giant black sphere.

“So he built the city.”

“Yes.”

“To escape the machine?”

“No.”

Lyra shook her head.

“To hide from it.”

Noah stepped closer.

“Why me?”

Lyra didn’t answer.

Noah’s voice became louder.

“Why did my older self send me here?”

“He wanted you to finish something.”

“What?”

Lyra pointed toward the Future Engine.

“Destroy it.”

Noah looked at the machine.

“Then why are you afraid of me?”

Lyra’s expression changed.

“Because you already tried.”

Noah froze.

“What?”

“Your older self destroyed the Future Engine.”

Noah looked confused.

“But it’s right there.”

“That’s not the original.”

“What do you mean?”

Lyra stepped closer.

“This is the second one.”

Noah’s face went pale.

“Second?”

Lyra nodded.

“Your older self built the first Future Engine in 2219.”

“He destroyed it in 2237.”

“Then he built another.”

“Why?”

“Because he had seen something.”

Noah waited.

Lyra looked into his eyes.

“He saw you.”

Noah’s stomach tightened.

“Me?”

“Your younger self.”

Lyra pointed toward the holographic timeline.

“Your older self discovered that you were the key to stopping the machine.”

Noah looked at the timeline.

“But I’m only seventeen.”

“Not anymore.”

Noah suddenly heard a noise.

A deep mechanical sound.

The Future Engine had activated.

Blue light filled the room.

The black sphere began spinning faster.

Noah stepped backward.

“What’s happening?”

Lyra looked terrified.

“The Engine knows you’re here.”

“How?”

“It recognized you.”

“No.”

The machine began producing a low vibration.

A voice came from inside it.

Not human.

Not mechanical.

Something between the two.

NOAH VEY IDENTIFIED.

Noah froze.

Lyra raised her weapon.

The voice continued.

ORIGINAL ARCHITECT CONFIRMED.

Noah looked at Lyra.

“What did it call me?”

Lyra’s face had gone completely white.

“The original architect.”

The machine opened.

Inside was a small chamber.

Noah saw a seat.

A control system.

And a single message.

WELCOME BACK, NOAH.

Noah stepped toward it.

Lyra grabbed his arm.

“Don’t.”

“Why?”

“Because your older self never sent you here to destroy the machine.”

Noah stared at her.

“Then why?”

Lyra looked at the machine.

“Because you are the machine’s creator.”

Noah’s blood ran cold.

“That’s impossible.”

Lyra shook her head.

“Your older self didn’t build the Future Engine.”

She pointed toward Noah.

“You did.”

Suddenly, the room shook violently.

The walls began to crack.

A massive explosion echoed somewhere above them.

Lyra looked toward the ceiling.

“They found us.”

“Who?”

“The Guardians.”

“Who are the Guardians?”

Lyra grabbed Noah’s hand.

“The people who protect the future.”

“From what?”

Lyra looked at him.

“From you.”

The door behind them exploded.

Armed soldiers entered the Archive.

Their armor was black.

Their faces were hidden.

The leader raised his weapon.

“Step away from the Architect.”

Noah froze.

The soldier looked directly at him.

“Your existence is a temporal crime.”

Lyra moved in front of Noah.

“He’s not your enemy.”

The soldier laughed.

“He is the beginning of everything.”

Noah looked at the Future Engine.

The machine suddenly activated again.

A vision appeared.

Noah saw the future.

He saw himself standing in a laboratory.

He was older.

He was building the first Future Engine.

Then he saw the floating city.

He saw billions of people escaping Earth.

He saw the city traveling through time.

Then he saw something else.

A dark figure standing behind his older self.

Noah couldn’t see its face.

But he heard its voice.

You built the city because I asked you to.

The vision changed.

Noah saw the future Earth.

It was empty.

Dead.

No cities.

No oceans.

No humans.

Only silence.

Then the dark figure turned toward Noah.

And spoke directly to him.

Now you must finish what you started.

The vision ended.

Noah opened his eyes.

The soldiers were gone.

The Archive was shaking.

Lyra was staring at him.

“What did you see?”

Noah looked at the Future Engine.

His voice trembled.

“I saw the end of humanity.”

Lyra stepped closer.

“And?”

Noah slowly looked at her.

“I saw who built the city.”

“Who?”

Noah’s eyes filled with fear.

“The city wasn’t built to save humanity.”

He looked toward the ceiling.

“It was built to save someone else.”

“Who?”

Noah whispered the answer.

“Something that was never supposed to exist.”

The Future Engine suddenly stopped.

Every light in the Archive went dark.

Then a final message appeared.

THE CITY WILL ARRIVE TOMORROW.

Noah stared at the words.

Lyra stepped backward.

“That’s impossible.”

“Why?”

“Because the city already arrived.”

Noah looked at her.

Lyra’s face was filled with terror.

“No.”

She pointed toward the ceiling.

“The city you saw in the sky…”

A deep rumble shook the entire underground complex.

Lyra whispered:

“That wasn’t the future city.”

Noah looked upward.

“Then what was it?”

Lyra’s voice trembled.

“The original.”

And far above them, hidden behind the clouds of the future…

the city of New Avalon began traveling backward through time.

Toward Noah’s world.

Toward the year 2199.

Toward the moment when Noah would first wake up…

and receive a message warning him not to go to school.
