Every Fourth of July, the tiny lakeside town of Ash Hollow celebrated the same way.
Children ran through the park with sparklers.
Families grilled hamburgers beneath rows of American flags.
The volunteer fire department launched a spectacular fireworks show from an abandoned quarry overlooking the lake.
No one remembered why the quarry had been closed decades earlier.
They simply knew not to wander beyond the rusted chain-link fence.
This year, nobody paid attention when twelve-year-old Mason claimed he heard banging beneath the old concrete launch platform.
“They’re setting up fireworks,” his father laughed.
But the banging continued long after the workers had gone home.
At exactly 9:30 p.m., the first rocket streaked into the sky.
The crowd erupted in applause.
Red.
White.
Blue.
The explosions echoed across the water.
Then something echoed back.
Not another firework.
A scream.
It came from the quarry.
A volunteer raced toward the launch site, only to disappear into the darkness. Seconds later, another scream shattered the celebration.
The fireworks continued automatically, each brilliant burst masking another cry for help.
People assumed it was part of the show.
Until a bloodied teenager stumbled into the field.
He collapsed before he could finish his warning.
“They’re…coming…”
The lights around the park suddenly died.
The only illumination came from fireworks bursting overhead.
Each flash revealed figures climbing from the quarry.
Men.
Women.
Children.
All coated in gray dust from decades underground.
They moved silently, their expressions frozen, their clothes from another era.
Then they charged.
Panic swept through the crowd.
Parents grabbed children.
People crashed into picnic tables and fled toward the parking lot.
The sheriff fired his pistol.
The figures never slowed.
One by one, they overwhelmed anyone who stumbled behind, vanishing into clouds of smoke and darkness as fireworks thundered overhead.
Deputy Rachel Collins sprinted toward the abandoned control shed.
Inside she found yellowed engineering maps.
The quarry wasn’t just a quarry.
It had once been an ammunition storage bunker during the Cold War.
Years earlier, an accidental collapse had sealed dozens of workers inside along with thousands of pounds of military explosives.
The official story had blamed flooding.
The truth had been buried beneath concrete.
Until tonight.
The endless pounding beneath the launch platform had been survivors’ descendants breaking through after decades trapped in the underground maze.
Only they were no longer entirely human.
Generations in darkness had twisted them into something driven only by rage.
Rachel spotted one final switch labeled:
Emergency Detonation.
The quarry had been designed to self-destruct if its ammunition became unstable.
Outside, hundreds of people were trapped between the fleeing crowd and the advancing figures.
The fireworks finale had already begun.
Hundreds of shells ignited simultaneously.
The ground trembled.
Rachel looked toward the lake.
Toward the terrified families.
Toward the quarry.
She pulled the switch.
For one heartbeat…
Everything became silent.
Then the earth exploded.
The quarry erupted in a deafening roar as decades of forgotten explosives ignited all at once. A towering column of fire shot into the night, brighter than every firework combined, turning darkness into daylight. The shockwave rolled across the lake, shattering windows for miles and knocking everyone to the ground.
When the smoke finally cleared…
The quarry was gone.
So were the creatures.
So were dozens of people who had been too close to escape.
The next morning, investigators called it the largest accidental fireworks explosion in state history.
No mention was made of the underground bunker.
Or the footprints leading away from the massive crater.
Footprints that emerged from the lake instead of the quarry.
Every Fourth of July since then, people in Ash Hollow swear that just before the first firework launches, they hear faint knocking beneath the ground.
Most pretend it’s their imagination.
No one stays for the finale anymore.
