At 4:10 a.m. UTC, every electrical system on Earth instantly dies—except in one mysterious city named Halden, which remains fully powered and sealed beneath an invisible, lethal dome. As the powerless world outside collapses into famine and chaos, Halden’s residents discover missing memories, impossible constellations in the sky, doppelgangers watching them from reflections, and a strange structure that appears overnight. A disembodied voice announces Halden has been “selected for observation.” When a seven-minute global power surge reveals a cosmic star map and a countdown, the truth becomes terrifyingly clear: Halden was removed from Earth during the blackout and only placed back temporarily. As the countdown ends, the entire landmass of the city rises from the planet’s crust and ascends into space. Humanity realizes the blackout wasn’t an attack—Halden was the experiment, and Earth was merely the control group.
I. The Second the World Went Dark
It happened at 4:10 a.m. UTC on a perfectly ordinary Wednesday, a moment so small in the grand scale of history that nothing should have marked it as special. Yet at that single, razor-thin second, billions of machines, wires, circuits, and grids across Earth died simultaneously.
Not failed. Not overloaded. Not surged.
Stopped.
Airplanes glided silently toward darkened airports. Pacemakers stuttered into stillness. Satellites flickered off like candles in a storm. Every screen faded into nothing.
The world became an unbroken ocean of darkness.
Except for one place.
A single city remained fully powered, shining like an island of stars in a dead universe. Streetlights glowed, traffic signals blinked, hospitals hummed, and people awoke confused to the sudden global silence outside their borders.
The city was called Halden.
A population of just under 600,000.
And for reasons no one understood, Halden alone survived.
II. The Enclosure
Panic outside Halden spread faster than hunger. Without power, fuel, communication, refrigeration, or medical infrastructure, the world collapsed in hours.
Refugees poured toward Halden from every direction, drawn to the glow like moths to the last flame.
But they couldn’t enter.
A truck loaded with desperate families hit an invisible barrier at high speed and vaporized into a fine mist. No explosion. No debris. Just instantaneous disintegration.
Scientists who approached on foot fared no better. One moment present — the next gone, replaced by drifting particles that glimmered briefly before dissolving.
Drones sent toward the city fell from the air before reaching the perimeter.
Geiger counters showed nothing abnormal. Thermal imaging revealed no heat signature. LIDAR returned impossible readings, as though the city was surrounded by infinite curvature.
Outside nations called it the Dome, even though no one could see it.
Inside Halden, residents went about their lives with functioning electricity… and a growing sense of dread.
They could see refugees beyond the invisible wall — thousands, then tens of thousands — banging, screaming, pleading.
And not a single person inside could open a window or door to hear them.
III. The Missing Day
On Halden’s third day of lonely illumination, the mayor called for a citywide emergency assembly. To everyone’s horror, it became clear that nobody inside the city could remember the previous twenty-four hours.
Not sleep. Not dreams. Not family dinners. Not what they were doing at the exact second the blackout began.
Every memory ended abruptly at the same moment, as if someone had cut the last day out of their minds with surgical precision.
Children sobbed, unable to recall whether they’d seen their parents the day before. Doctors found no neurological damage. Psychologists found no trauma markers.
It wasn’t forgetting.
It was removal.
And the removal was perfect.
IV. The Sky That Was Not Our Sky
That night, an astronomer named Dr. Luna Gavrik climbed to the top of Halden’s observatory and aimed her telescope upward.
Then she screamed.
Above the city, the night sky was wrong.
Constellations were shifted. Stars burned too brightly, too sharply. Nebulae glowed in hues never visible from Earth. And where the Moon should have been, an unfamiliar crescent hovered — smaller, redder, scarred across its equator.
Dr. Gavrik recalibrated, recalculated, rechecked her coordinates.
The conclusion was impossible.
Halden wasn’t seeing Earth’s sky.
Halden wasn’t on Earth’s sky side.
It wasn’t on Earth at all.
V. The Broadcast
At dawn, every speaker in Halden—from phones to radios to toys that no longer had batteries—began emitting a soft hum. Then the hum became a voice.
Calm. Measured. Inhuman.
“This place has been selected.”
People froze in their homes, workplaces, parks.
“For observation.”
A long silence followed, so heavy it felt like pressure on the bones.
“Do not be alarmed. We are studying continuity.”
No further explanation came.
The voice ceased.
Every speaker shattered.
VI. The Doppelgangers
Within days, residents began reporting strange sightings: perfect doubles of themselves walking silently through streets, staring through windows, turning corners only to vanish.
They did not speak. They did not mimic. They simply watched.
One woman found her double standing in her kitchen at midnight, smiling faintly. When she screamed, the double dissolved into shimmering particles that drifted upward through the ceiling.
Another resident filmed his reflection moving independently in a powered-off television screen. When he blinked, the reflection did not.
Scientists attempted to trap the doppelgangers, but nets, magnets, and containment chambers all failed—the doubles simply phased through walls like projections shifting dimension.
Not illusions. Not hallucinations.
Echoes.
As though Halden were being “read” from multiple angles.
VII. The Structure
On the eighth day, citizens awoke to find a new building standing in the city’s central plaza.
It had not existed the night before.
No one saw it appear.
It was smooth, metallic, and alabaster white—impossible to touch without feeling as if the skin was vibrating at two frequencies simultaneously.
Symbols coursed along its surface, shifting like fluid light.
Children approached it without fear.
Adults could barely stand near it.
Dr. Gavrik discovered that every symbol matched the unknown constellations above them.
Others found that if they pressed their hands to the structure, they experienced sudden blackouts lasting exactly seventeen minutes. When they awoke, they carried vivid memories of impossible landscapes—mountain ranges floating upside down, oceans suspended like rings around distant planets, cities made of mirrors stretching into infinity.
None of these places were Earth.
And yet every person felt an ache of familiarity, as if remembering somewhere they had lived long before their birth.
The structure was not built.
It was grown.
VIII. The World Outside
Meanwhile, outside Halden, the world was imploding.
With no electricity, no pumps, no refrigeration, billions were starving. Governments dissolved. Armies splintered.
Around the glowing Dome, desperate factions formed.
The Pilgrims believed Halden contained divine salvation. The Purifiers believed Halden caused the blackout and must be destroyed. The Echoes claimed to hear the same voice Halden heard, but from beneath the Earth. The Nulls—children born after the blackout—could not perceive Halden at all. When shown its bright lights, they saw only darkness.
Warfare erupted among these factions, each fighting for control of the Dome.
None ever breached it.
Some never even reached it—those who approached too closely simply vanished.
Halden, for all its illumination, had become the most isolated place in the world.
IX. The Seven-Minute Window
On the thirteenth night, at 2:00 a.m., the Dome flickered.
Power surged outward from Halden like a shockwave.
For seven minutes, electricity returned to the entire planet.
Lights blazed. Hospitals roared back to life. Satellites reconnected. Phones lit up.
Every screen in the world—inside and outside Halden—displayed the same image:
A star map. Unfamiliar. Vast. Dotted with pulsating markers.
Then the countdown appeared. A silent, relentless sequence.
7:00 6:59 6:58…
Panic spread. People screamed. Scientists ran toward the Dome. Children whispered to empty air as if being spoken to.
When the countdown reached zero, the structure in Halden pulsed once—so brightly that every shadow in the city vanished.
Then a new voice spoke:
“You were not chosen for survival.”
The lights across Earth died again. Halden stayed bright.
“You were chosen for observation.”
The Dome grew brighter, shimmering like heat distortion.
“For continuity.”
The ground trembled beneath Halden. Not like an earthquake. More like something gripping the bedrock from below.
X. The Extraction
At sunrise, Halden began to rise.
Not its buildings. Not its people. The entire landmass of Halden—the actual ground—broke free from the Earth’s crust like an island peeling loose.
Streets warped. Highways cracked. The coastline ruptured as Halden’s foundation lifted, shedding soil and concrete like dust.
People screamed as gravity wavered.
Children pointed upward.
Dr. Gavrik realized the impossible truth:
Halden wasn’t protected during the blackout.
Halden had been removed during the missing day.
Removed, studied, catalogued, and then… returned.
“We were not spared,” she whispered. “We were taken.”
And now they were being taken again.
As Halden ascended into the sky, leaving the dead Earth behind, the Dome shimmered into visibility for the first time.
It was not a barrier.
It was a shell.
A cocoon.
The voice spoke one final time:
“Control group: terminated. Subject: preserved. Continuity: assured.”
Halden rose past the atmosphere. Past the clouds. Past the exosphere.
The stars above shifted into their unnatural constellations.
Halden was no longer on Earth.
Halden had never truly been returned to Earth.
And as the city drifted into the void, the people looked upward and finally understood the countdown:
It wasn’t counting down to extinction.
It was counting down to departure.
Because Halden had never belonged to humanity.
It belonged to them.
Wherever they were.
Wherever Halden was now going.
And the world outside, powerless and dark, finally understood the greatest horror:
The blackout wasn’t the experiment.
Humanity was.
