The creature crashed onto the factory floor with enough force to shake the metal beneath their feet.
The others moved instantly.
Dozens of burned figures emerged from the darkness between the old machines.
Their glowing symbols pulsed like hot iron.
Ben raised the shotgun.
"Dean, I would just like to say—"
A creature lunged at him.
BOOM
Ben blasted it backward into a furnace.
"—this is officially the worst place we've ever been!"
Dean fired the Colt.
BANG
The sigil bullet ripped through another creature's chest in a burst of orange light.
The monster exploded into ash instantly.
But there were too many.
The creatures kept coming.
Dean grabbed Ben's jacket.
"Move!"
They sprinted deeper into the foundry as claws slammed into the metal behind them.
Old conveyor belts rattled beneath their feet.
Steam hissed from broken pipes overhead.
Ben shoved another shell into the shotgun.
"Any chance Bobby left us a magical nuke in here?"
Dean scanned the room quickly.
Then he saw it.
At the far end of the foundry—
An enormous furnace.
Unlike the others, it was still burning.
Orange light flickered behind thick iron doors.
Ben followed Dean's gaze.
"…Why is that still on?"
Dean's expression darkened.
"Because someone's been using it."
One of the creatures dropped from above directly in front of them.
Its burned skin cracked as it moved.
Dean punched it hard across the jaw.
The creature staggered.
Ben fired point-blank.
BOOM
The monster flew backward into a steel beam.
Dean grabbed the Colt casing from his pocket.
The emergency sigils.
Then suddenly—
He remembered Bobby's letter.
The original bullets required more than silver.
Dean stopped running.
Ben nearly crashed into him.
"Dean?!"
Dean looked toward the furnace.
Then at the Colt.
Then at the glowing creatures.
And finally smiled slightly.
Ben immediately looked worried.
"That's the exact same look you had before driving a car into a supernatural gate."
Dean ignored him.
"The foundry isn't abandoned."
Ben frowned.
"Yeah, I noticed!"
Dean shook his head.
"No. I mean someone's still forging here."
A loud metallic groan echoed through the room.
The giant furnace doors slowly opened by themselves.
Heat flooded the foundry instantly.
Inside the flames—
Something moved.
Slow.
Heavy.
Ben stared.
"…Okay I officially miss regular demons."
A massive figure stepped out of the furnace.
Twice the size of the others.
Its body looked forged from molten metal and burned bone.
And engraved across its chest—
The same symbol carved into the Colt.
Dean whispered:
"The blacksmith."
The giant creature's glowing eyes locked onto the revolver instantly.
Then it spoke with a voice like grinding steel.
"The weapon returns."
Every creature in the foundry suddenly stopped moving.
Watching.
Waiting.
Dean slowly raised the Colt.
The blacksmith looked almost amused.
"One bullet."
Its molten smile widened.
"Not enough."
Ben looked at Dean.
Then at the furnace.
Then back at Dean.
"…Please tell me you have a plan."
Dean reached into his pocket and pulled out Bobby's silver sigils.
The heat from the furnace reflected in his eyes.
Then Dean smiled.
A dangerous Winchester smile.
"Yeah."
He tossed Ben a box of silver rounds.
"We make more."
The blacksmith roared.
The creatures charged.
And behind Dean—
The ancient furnace burned hotter than ever.
