Darkness swallowed Ebon City.
The citywide blackout continued as the Dominion fleet loomed overhead, its colossal warships blotting out the stars. Emergency generators flickered to life across hospitals and government buildings, but most of the city remained cloaked in shadow.
Only one light stood against the darkness.
The blue glow radiating from Kairo's chest.
He hovered above the shattered streets, facing the Dominion flagship suspended thousands of meters above him.
Beside him floated Serak, gripping his energy spear.
Far below, Revenant stood atop a collapsed skyscraper, his crimson eyes fixed on the young Guardian.
For the first time, all three powers had gathered on one battlefield.
High Commander Lysera's voice echoed across every communication network on Earth.
"Guardian."
"You have one minute."
"Surrender the Shadow Core."
"Refuse..."
"And this city dies."
As she spoke, dozens of Dominion attack cruisers descended lower over Ebon City.
Their weapon ports unfolded.
Red energy gathered inside enormous plasma cannons.
Kairo clenched his fists.
"They're bluffing."
Serak slowly shook his head.
"No."
"The Dominion never bluffs."
Below them, millions of civilians searched desperately for shelter.
Parents carried frightened children.
Police struggled to control the growing panic.
Hospitals filled beyond capacity.
The countdown had begun.
Deep beneath the city, Commander Voss watched the broadcast from his command center.
One of his officers turned toward him.
"Sir, if the Dominion attacks..."
"They'll destroy everything."
Voss smiled.
"They're giving us an opportunity."
"What opportunity?"
"Chaos."
He enlarged a holographic image of Kairo.
"While the world watches the invasion..."
"We take the Shadow Core."
Back in the sky, Kairo stared at the countless warships.
He whispered to the Shadow Core.
"If I surrender..."
The Dominion will conquer countless worlds.
"If I refuse..."
Millions may die today.
Kairo closed his eyes.
Neither choice felt right.
Then he remembered something his grandmother had once told him.
"When every choice seems wrong, make the one that protects the most people."
He opened his eyes.
"I need another option."
The Shadow Core pulsed brightly.
Then create one.
Without another word, Kairo rocketed toward the Dominion flagship.
Serak shouted after him.
"Kairo!"
The young Guardian ignored the warning.
Blue energy exploded behind him as he accelerated through the clouds.
Dominion fighters immediately intercepted.
Dozens of sleek black craft surrounded him.
Energy cannons fired from every direction.
Kairo spun through the storm of plasma blasts.
One fighter swooped too close.
He struck its wing with a glowing punch.
The craft spiraled away, colliding with two more.
A chain of explosions lit the sky.
But there were too many.
Another blast struck Kairo across the back.
Pain surged through his body.
He tumbled through the air before regaining control.
The Shadow Core spoke urgently.
Energy reserves at sixty-two percent.
"I'll worry about that later."
He pushed forward.
The flagship continued growing larger until it filled his entire field of vision.
Its armored hull stretched for kilometers.
Thousands of gun batteries tracked his approach.
Then...
A golden figure stepped into open space.
High Commander Lysera.
She floated effortlessly before the massive ship without any visible technology.
Golden energy surrounded her like a living sun.
"So," she said calmly.
"The newest Guardian finally arrives."
Kairo stopped several meters away.
"You don't have to destroy Earth."
Lysera folded her hands behind her back.
"I do not seek your world."
"I seek the Core."
"It belongs to no one."
"It belongs to history."
Her golden eyes studied him carefully.
"You are young."
"Inexperienced."
"You do not understand the burden you carry."
Kairo refused to look away.
"Then explain."
For the first time, Lysera's expression softened.
"The Shadow Core and the Void Core were never meant to exist."
"They divided the greatest Guardian who ever lived."
Kairo's heart skipped.
"Revenant..."
"His true name was Caelan."
"He protected galaxies."
"He inspired peace."
"Then fear consumed him."
"He believed absolute order required absolute control."
"The Guardians opposed him."
"They shattered the ancient power into two halves."
"The Shadow Core."
"The Void Core."
"They hoped balance would be restored."
"It wasn't."
Kairo listened silently.
"So this war..."
"...has lasted for thousands of years."
Lysera nodded.
"And it ends today."
Before Kairo could answer, the sky exploded.
A streak of black lightning slammed into Lysera.
She was hurled backward.
Another figure landed between them.
Revenant.
His sword burned with Void energy.
"I remember you," he said quietly.
Lysera rose slowly.
"I remember the hero you once were."
"He is gone."
"Not completely."
For the briefest moment, uncertainty crossed Revenant's face.
Then the Void Core flared again.
Darkness overwhelmed him.
He attacked.
Their clash shook the heavens.
Golden light collided with crimson darkness, creating shockwaves that rolled across the clouds.
Kairo watched in disbelief.
Neither warrior seemed human anymore.
Each strike split the sky with thunder.
The Dominion fleet paused.
Even its soldiers watched.
Far below, citizens of Ebon City looked upward as flashes of gold and crimson illuminated the night.
The Shadow Core whispered.
Now.
"What?"
Their battle has created an opening.
Kairo understood.
If he could reach the flagship...
Perhaps he could disable its weapons.
He shot past the battling titans toward the enormous vessel.
Dominion soldiers opened fire.
He dodged through corridors of plasma.
Landing on the flagship's outer hull, he searched for a way inside.
A circular hatch suddenly opened.
Rows of armed Dominion guards emerged.
Kairo took a deep breath.
"I guess we're doing this."
Blue-black energy surged around him as he charged into the enemy ranks.
For the first time, Shadow Born carried the battle directly onto the flagship of the most powerful empire in the galaxy.
Behind him, Earth waited.
Ahead of him lay the heart of the invasion.
And deep within the flagship, hidden from every scanner...
An ancient prison began to awaken.
Something inside smiled.
It had been waiting thousands of years for the Shadow Core to return.
