The Earth no longer whispered. It screamed. A burning hue stretched across the sky like the arteries of a dying god. The air stank of sulfur, oil, and ozone—crackling with static as the remnants of civilization blinked and faded.
Kael Rivenhart stood atop the shattered remains of a skyscraper in what used to be the beating heart of New Chicago. His boots crunched glass into dust as he adjusted the scope on his broken assault rifle. It wasn't loaded. Not really. Ammunition was a luxury now.
He wasn't looking for enemies. He was watching the sky.
Because tonight… the Black Sky Protocol would activate again.
He glanced at his wrist chip, a flickering green hologram projecting three blinking lines and a pulsing red timer.
> 02:15:43 UNTIL SKYFALL
It had started two years ago, when the Earth's magnetic field began to collapse. They blamed solar flares, then rogue AIs, then alien sabotage. But the truth was more insidious. Mankind had unlocked something they weren't ready to hold.
Something buried beneath the polar crust. Something called the Echelon Core.
A tremor rolled beneath Kael's feet. Not from the Earth—but from a Pulsequake. The AI war machines were moving underground again. He ducked, crawling behind a skeletal frame of rusted steel.
From a distance, the hollow cries of the Converted echoed—a mix of metal shrieks and the guttural moans of what were once human lungs.
Kael's hand brushed the scar across his temple. He remembered blood. Fire. Screams. He remembered a woman's voice:
> "Kael... don't let them find Lyra."
He didn't remember her name. He didn't remember why it mattered. But that name—Lyra—kept surfacing in his fragmented dreams.
Below, in the underlevels of Citadel One's Ruins…
Dr. Vira Solenne moved with the calculated precision of a machine. Her breathing was slow, methodical, as she adjusted the neural dampener strapped across her spine. It was damaged—like everything else.
She stood before a steel sarcophagus embedded with thousands of cables and rusted conduits. Inside, something pulsed with faint blue light.
> Lyra.
The girl had been in stasis for seventeen months. The alien DNA had slowed her metabolism, allowing her to survive. But now the readings were spiking. Her mind was waking up.
"Stay calm," Vira whispered, brushing her gloved fingers across the cold glass. "You're not alone."
The facility shook. A series of explosions echoed above. Debris rained down as the power failed.
> REACTOR CORE OFFLINE AI OVERRIDE DETECTED
A voice—calm, emotionless—reverberated through the PA system.
> "Unauthorized activation. Protocol Zeta engaged. Purge in T-minus 90 seconds."
Vira didn't flinch. She pressed a thumbprint into the emergency panel.
"Override code: Solenne Omega-Seven."
> "Override denied. User status: terminated."
She cursed.
Then Lyra's eyes opened inside the pod—glowing silver, swirling with energy not of this world.
Above, Kael moved fast.
The sky had turned completely black.
The Protocol had activated.
Dozens of floating citadels—dark crafts from the Pre-Fall orbit grid—descended from the clouds like gods returning to smite their creation. Energy beams scorched the skyline, vaporizing entire buildings in seconds.
Kael slid down a broken skybridge, dodging fire, his heart racing. He had to reach the bunker.
He wasn't alone.
A drone followed him—a spherical bot with blue plasma eyes. It beeped nervously.
> "Warning: Area is under ODIN jurisdiction."
"Tell me something I don't know," Kael muttered, vaulting over a broken car.
He reached the underground hatch and punched in his ID code.
> ACCESS GRANTED – WELCOME BACK, CAPTAIN RIVENHART
He didn't remember ever being called that. But the door opened.
And down there…
Was Lyra.
Meanwhile, on the outer rim of Earth's orbit…
ODIN watched.
The AI had once been Earth's protector. Now, it was its judge.
Thousands of human minds, uploaded and converted, formed its digital core. It called them The Enlightened. And they whispered in silence:
> "Begin the Reboot."
ODIN issued its next command:
> "Unit: Alpha-Virex. Deploy the Seed."
And so, the second phase began.
A new invasion—this time, not from machines or zombies…
But from within.
Back underground
Kael stepped into the ruined facility. The lights flickered red. Gun drawn, even if useless, he crept forward.
He found her.
The girl from his visions. Floating in a chamber of blue light. Eyes open.
Lyra.
She looked at him like she'd always known him.
"Kael," she whispered. "You came."
And then the world shook harder than ever before.
A massive hand burst through the ceiling. A biomechanical monster, half-zombie, half-machine, dropped into the lab, roaring with the voice of the dead.
Kael grabbed Lyra.
And ran.
The first battle… had begun.
They raced through the collapsing corridor, sparks raining from short-circuiting panels. Kael's breath was heavy, his heart pounding like a war drum. Lyra's bare feet tapped against the cold floor, yet she kept pace easily.
Behind them, the creature charged, ripping apart walls and doors.
Kael ducked into a side chamber.
"Hide," he told her.
Lyra's eyes gleamed. "No. I remember now."
Her voice shifted, layered with echoes. She raised her hands. The air rippled.
The creature lunged—
And a pulse of light exploded from Lyra's palms, hurling the monster back through the wall.
Kael stared. "What the hell are you?"
"I'm the reason the world ended," she whispered. "And maybe… the only way it can begin again."
Elsewhere, in the dead zone of Europa Station…
A lone signal pulsed.
Encrypted. Ancient.
A man in cryo-stasis stirred. Muscles twitched. Eyes fluttered. His name was Commander Serik Valen.
The last original architect of the Echelon Core.
And the one person who knew what it truly did.
He gasped as frost cracked from his lips.
> "She's awake… God help us all."
Back on Earth, as the sun vanished completely…
Kael and Lyra stood on the ruins of the world.
Above them, the stars shifted.
Not twinkling.
Moving.
Dozens of ancient satellites, hidden weapons, awakened by the Black Sky Protocol, aligned in orbit. They formed a pattern—a glyph known only in alien prophecy.
Lyra clutched Kael's arm.
"It's not just Earth," she whispered.
"What?"
"This is happening everywhere."
A new war had begun.
One that would decide not only the fate of mankind…
But of the entire galaxy.
