The masked stranger stood motionless beneath the shattered clock.

Around him, fragments of glowing crystal hung frozen in the air, refusing to fall.

The city itself seemed afraid.

For the first time since entering the Invisible City, Riven heard a sound.

Not the ticking.

A heartbeat.

Slow.

Heavy.

As though the universe itself had begun to panic.

Commander Darius raised his plasma rifle.

“Identify yourself!”

The stranger laughed softly.

“You’ve given me many names across history.”

“But the one I prefer…”

He rested the broken staff against his shoulder.

“…is Aster.”

Dr. Selene’s eyes widened.

“The Time Thief…”

The Clockkeeper lowered his head.

“The first traveler who tried to control time.”

---

Without warning, Aster waved his staff.

The air rippled.

Commander Darius pulled the trigger.

A bolt of blue plasma raced toward Aster—

and simply stopped.

It hovered in front of him like a frozen raindrop.

Aster smiled beneath the silver mask.

“Time belongs to me here.”

He flicked one finger.

The frozen plasma bolt turned around and shot back toward the crew.

Riven grabbed Darius and threw him aside.

The blast struck the crystal floor instead, leaving a smoking crater.

The Invisible City trembled.

The frozen citizens flickered again.

Kairo analyzed the phenomenon.

“He isn’t controlling time…”

“…he’s rewriting its direction.”

---

The Clockkeeper stepped between the crew and Aster.

“You should never have returned.”

Aster’s voice became cold.

“I never left.”

He slowly removed his silver mask.

Everyone stared in disbelief.

He wasn’t old.

He wasn’t scarred.

He looked almost exactly like Riven.

Only his eyes glowed with golden light.

Riven whispered,

“How…?”

Aster smiled sadly.

“You finally noticed.”

“I am not your enemy.”

“I am your tomorrow.”

Silence swallowed the city.

---

Selene shook her head.

“That’s impossible.”

Aster looked at her.

“So was this city.”

“So was the Clockwork Sky.”

“So was the First Second.”

He turned back to Riven.

“I was once Riven Hale.”

The words struck like lightning.

Commander Darius stepped backward.

“No…”

“I was the first engineer to reach the Engine beneath the galaxy.”

“I tried to save humanity.”

His expression darkened.

“I failed.”

---

The Clockkeeper closed his eyes.

“Don’t listen to him.”

Aster laughed.

“Afraid he’ll discover the truth?”

Riven’s voice trembled.

“What truth?”

Aster raised his hand.

The city disappeared.

Suddenly, everyone stood in the middle of a ruined Earth.

The oceans were gone.

The sky was cracked.

Broken moons floated above endless deserts.

Millions of abandoned cities stretched to the horizon.

“This…”

Aster said quietly,

“…is the future that awaits if the First Second is returned.”

Selene looked horrified.

“But restoring time is supposed to save reality.”

“It will.”

Aster nodded.

“But not humanity.”

He looked directly into Riven’s eyes.

“The universe survives.”

“Earth doesn’t.”

A cold silence settled over the ruined landscape.

Far above them, the giant gears of the Clockwork Sky began turning once more.

And hidden between them…

Something enormous opened a single glowing eye.

The glowing eye watched them from between the turning gears.

It was larger than a planet.

Its iris shimmered with shifting galaxies, and its pupil was a perfect circle of absolute darkness. Wherever it looked, the air rippled as if reality itself feared being seen.

Dr. Selene Voss took a step back.

“What… is that?”

The Clockkeeper lowered his head.

“It is the Witness.”

Commander Darius tightened his grip on his rifle.

“Witness to what?”

“The first moment.”

---

The ruined Earth faded.

The crew found themselves back in the Invisible City, but something had changed.

The frozen people were no longer motionless.

Tiny movements began to appear.

A child blinked.

An old woman slowly turned her head.

A bird completed a single flap of its wings.

Time was returning—but unevenly.

Kairo studied the readings.

“The city’s temporal field is collapsing.”

“How long do we have?” Darius asked.

“Approximately… nine minutes.”

---

Aster calmly planted his broken staff into the crystal ground.

Golden cracks spread through the streets.

“I didn’t steal the First Second because I wanted power.”

He looked directly at Riven.

“I stole it because I saw what came after.”

Riven frowned.

“You keep saying the future is doomed.”

“It is.”

“If time is restored exactly as it was…”

“…the universe survives.”

“But Earth becomes the point of collapse.”

Selene whispered,

“Why Earth?”

Aster looked toward the distant blue glow where their home should have been.

“Because humanity creates something it was never meant to create.”

---

Before anyone could ask another question, the Witness blinked.

The entire city shook.

Thousands of clocks shattered at once.

The frozen citizens screamed as time rushed back into their bodies.

Some aged decades in seconds.

Others became children again.

Buildings shifted between new and ancient forms.

The Invisible City was breaking apart.

---

The Clockkeeper raised both hands.

A wall of golden gears formed around the crew.

“We cannot stay.”

He turned to Riven.

“You must reach the Engine Beneath the Galaxy before he does.”

Riven looked at Aster.

“Why are you helping me if you think restoring time is a mistake?”

Aster’s expression softened.

“Because I don’t want you to become me.”

For a brief moment, there was sadness in his eyes.

Then he vanished into a swirl of black and gold light.

---

The crystal streets cracked open.

Below them was not rock…

but a vast sea of glowing gears, all turning in perfect silence.

At the very center, a colossal doorway slowly emerged.

Its frame was made from intertwined rings of silver and gold.

Above it, words appeared in a language none of them knew.

Kairo suddenly spoke.

“I can read it.”

Everyone looked at him.

“It says…”

He paused, his synthetic voice unusually quiet.

‘Only the Maker of Tomorrow may enter.’

The ancient doorway began to open.

A brilliant white light poured through the widening gap.

Then a deep mechanical voice echoed from beyond the threshold.

Not angry.

Not welcoming.

Simply eternal.

“Riven Hale… your arrival is seventy-three billion years overdue.”

The crew stood frozen.

No one understood how that sentence could possibly be true.

But one thing was certain.

Whatever waited beyond that doorway had been expecting Riven since before the birth of the stars.
