The heartbeat came again.
Boom.
The sound traveled through the stone beneath their feet.
Nobody moved.
For several seconds, the entire chamber remained frozen in silence.
Then—
Boom.
Dust fell from the ceiling.
One of the researchers stepped backward.
"That wasn't machinery."
Cain didn't take his eyes off the passage.
"No."
Iria looked at Kael.
"Can you feel it?"
Kael stared into the darkness.
"Yes."
"What is it?"
"I don't know."
Cain glanced at him.
Kael gave him an annoyed look.
"Don't."
"I didn't say anything."
"You were thinking it."
Cain almost smiled.
Then the heartbeat came again.
Boom.
This time Kael felt something else.
The sensation didn't come from the passage.
It came from below.
Far below.
Something was transmitting the sound through the stone.
Kael crouched and placed his palm against the floor.
Cold.
Then warmth.
Then—
A pulse.
His golden mark appeared.
The seven illuminated circles on the wall brightened.
The researchers immediately began recording.
"Energy increase!"
"How much?"
"Thirty percent!"
"That's impossible."
"Keep recording!"
Kael lifted his hand.
The glow faded.
The seven circles dimmed.
Everyone stared at him.
Varen's representative slowly approached.
"Do it again."
Kael looked at him.
"No."
The researcher frowned.
"Why?"
"Because I don't know what happened."
"But the system reacted to you."
"And if I trigger something we can't stop?"
The researcher fell silent.
Cain nodded.
"He's right."
The man looked annoyed but stepped back.
The chamber returned to silence.
Kael stared at the hidden passage.
The darkness seemed deeper now.
Heaven's Gate remained closed, but he could feel it waiting.
Hell's Gate was quieter.
Yet it was there.
For the first time, Kael understood that the two Gates did not always respond in the same way.
Heaven's Gate felt like something he could reach.
Hell's Gate felt distant.
Not weaker.
Farther.
As if there were something between him and it.
A barrier.
A separation.
Or perhaps a decision.
He didn't know.
And he wasn't sure he wanted to find out.
Cain raised his weapon.
"We continue."
One of the researchers looked at him.
"Director Varen ordered us to investigate the structure, not enter an unknown passage."
Cain glanced toward the dark opening.
"We've already entered an unknown structure."
"That's different."
"How?"
The researcher opened his mouth.
Nothing came out.
Cain turned toward Kael.
"You coming?"
Kael stood.
"Obviously."
Iria followed.
The others exchanged uncertain looks.
Eventually, they moved forward.
The passage descended.
At first, it was narrow enough that they had to walk in a single line.
The walls were covered with the same symbol.
Circle.
Vertical line.
But after several meters, the symbol changed.
Some circles were divided into two.
Others had lines extending outward.
A few contained small marks resembling fragments.
Kael noticed something strange.
The symbols were not instructions.
They looked like records.
Different symbols represented different stages.
He pointed toward one.
"Look."
The researcher beside him examined it.
"What?"
"This one has six marks."
The researcher counted.
"Six."
Kael moved farther.
Another symbol.
Seven.
Then another.
Eight.
Kael stopped.
"There's one with eight."
Cain looked back.
"But we only have seven."
"Exactly."
The corridor became silent.
Iria examined the wall.
"Could it be another fragment?"
"Maybe."
"Then why hasn't it awakened?"
Kael shook his head.
"Maybe it already did."
Cain turned.
"Eight?"
Kael looked at the wall.
"Maybe."
He didn't like the thought.
If another fragment had awakened without being detected, their entire count could already be wrong.
But the researchers had confirmed seven unique energy signatures.
Thirty-six total.
Seven active.
Twenty-nine dormant.
Unless—
Kael stopped thinking.
There were too many possibilities.
He continued walking.
The corridor eventually opened into a large circular room.
There were no doors.
No exits.
Only twelve stone pillars arranged around the walls.
Each pillar carried a different symbol.
The center was empty.
Kael walked toward it.
His footsteps echoed.
Once.
Twice.
Then a third echo returned.
Kael stopped.
The others continued.
Cain looked back.
"What?"
Kael raised a hand.
"Listen."
Everyone became quiet.
Nothing.
Then—
Step.
A sound.
Not theirs.
Somewhere behind them.
Cain turned immediately.
Nothing.
Another step.
This time from the opposite side.
Iria's weapon appeared in her hand.
"There's someone here."
The researchers gathered together.
Cain moved to the center.
"Show yourself."
Silence.
Kael closed his eyes.
Heaven's Gate stirred.
He didn't open it.
Instead, he focused on the sensation.
There.
Something.
Not a monster.
Not human.
Not exactly energy.
It felt like an absence.
A place where something should have been.
Kael opened his eyes.
"Over there."
He pointed toward one of the pillars.
Cain moved.
Nothing.
Then the pillar cracked.
A thin black line appeared across its surface.
Kael stepped backward.
The crack widened.
A hand emerged.
The researchers screamed.
Cain attacked.
The hand vanished.
The pillar collapsed.
Stone exploded across the chamber.
Everyone raised their weapons.
But nothing came out.
Kael stared at the broken pillar.
"There was something inside."
Cain nodded.
"Yes."
"What was it?"
"No idea."
Iria walked toward the rubble.
"Look."
A small object lay among the stones.
Not a fragment.
A piece of metal.
Ancient.
It was shaped like a key.
Kael picked it up.
The moment his fingers touched it, the seven marks on his hand appeared.
The key became warm.
A symbol appeared across its surface.
Kael dropped it.
It landed on the floor.
The entire chamber shook.
The twelve pillars began glowing.
One.
Two.
Three.
Four.
The glow traveled around the room.
By the time it reached the seventh pillar, Kael felt the Gates respond.
The eighth pillar remained dark.
The ninth.
Tenth.
Eleventh.
Twelfth.
The researcher whispered, "Seven."
Kael looked at him.
"What?"
"Seven pillars."
He pointed.
"The first seven are responding."
Kael stared.
The key on the ground began moving.
It slid toward the center of the chamber.
Then stopped.
A circle appeared beneath it.
The same circle-and-line symbol.
A voice came from the walls.
Not a person.
Not a recording.
A resonance.
A single word.
"Return."
Kael's stomach tightened.
The word disappeared.
The chamber went dark.
Then the floor opened.
They fell.
Kael had barely enough time to activate Heaven's Gate.
Golden light erupted around him.
The fall slowed.
He grabbed Iria's arm.
Cain caught one of the researchers.
The others used their own abilities or equipment.
They descended through darkness.
The walls blurred past them.
Ten meters.
Twenty.
Thirty.
Then the shaft ended.
Kael landed hard.
Iria landed beside him.
Cain landed several meters away.
The researchers crashed into the ground.
Everyone groaned.
Kael stood.
"Everyone alive?"
Several voices answered.
Cain looked upward.
The shaft was too high to see the opening.
"We're trapped."
Kael looked around.
They were in another chamber.
This one was enormous.
The ceiling was invisible.
The walls disappeared into darkness.
But something stood at the center.
A structure.
It looked like a throne.
Except there was nobody sitting on it.
Kael approached slowly.
The structure was made from black stone.
Its surface was covered in hundreds of tiny marks.
Some looked like cracks.
Others looked like writing.
At the base was a circular depression.
The key they had found was glowing in Kael's hand.
He looked down.
"I didn't pick it up."
Cain frowned.
Kael opened his hand.
The key was there.
It hadn't been there a moment ago.
Iria stepped closer.
"Maybe the room moved it."
Kael looked at the throne.
"Maybe."
He placed the key into the depression.
Nothing happened.
Then—
Boom.
The heartbeat returned.
The throne cracked.
Black light emerged.
Kael stepped back.
A shape appeared above it.
Not a body.
An outline.
For a moment, it resembled a human.
Then an animal.
Then something with wings.
Then something Kael couldn't describe.
The shape kept changing.
One of the researchers whispered, "What is that?"
Kael didn't answer.
The shape moved.
It reached toward the throne.
Then disappeared.
The heartbeat stopped.
Silence.
The key shattered.
Kael stared at the broken pieces.
"That's not good."
Cain looked around.
"Why?"
"Because whatever this place was built for..."
Kael looked at the empty throne.
"...it isn't empty anymore."
A tremor shook the chamber.
The researchers gathered together.
Cain raised his weapon.
"Movement."
Kael looked into the darkness.
There were shapes.
Hundreds.
Small points of light appeared across the walls.
Not eyes.
Fragments.
Tiny black pieces embedded in the stone.
Iria counted the nearest ones.
"Dozens."
Kael walked closer.
They weren't fragments like the seven.
They were smaller.
Much smaller.
Pieces of something.
Fragments of fragments.
Heaven's Gate reacted.
Kael immediately stepped back.
"No."
Cain looked at him.
"What?"
"Don't touch them."
"Why?"
"They're connected."
"To the seven?"
Kael shook his head.
"Something else."
The black pieces began glowing.
One after another.
The chamber slowly illuminated.
And Kael saw the walls.
Thousands of drawings.
Thousands of symbols.
Thousands of figures.
Some human.
Some monstrous.
Some impossible to understand.
All of them were arranged around a single image.
A chest.
Kael's breath stopped.
Not Heaven's Chest.
The older chest.
The one from his visions.
It stood at the center of the mural.
Thirty-six circles surrounded it.
But this time, the circles were not empty.
They were connected by lines.
The lines formed a vast network.
Kael stepped closer.
The researchers began photographing everything.
Cain stood beside him.
"Do you recognize this?"
"Yes."
"From the dreams?"
Kael nodded.
The mural showed the chest opening.
Inside it was darkness.
Then another image.
The chest was closed.
Then another.
The chest was broken.
Then another.
The fragments were scattered.
Kael followed the sequence.
His eyes narrowed.
"The fragments were separated."
Cain looked at the mural.
"By whom?"
Kael shook his head.
The next image showed figures carrying the fragments away.
They traveled in different directions.
One went toward mountains.
Another toward a forest.
Another toward the sea.
Another disappeared underground.
Then the mural changed.
A new figure appeared.
It stood alone.
No fragment.
No group.
No symbol.
The figure was drawn differently from the others.
Its body had several overlapping outlines.
Its head was incomplete.
Its arms were different lengths.
Its shape changed between each section of the mural.
Kael stared.
He remembered the vision.
The unstable figure.
The one without a fragment.
But the mural didn't identify it.
There was no name.
No title.
Only a symbol beneath it.
A broken circle.
Kael didn't touch it.
Something inside him told him not to.
He moved on.
The final section showed the fragments scattered across the world.
Then seven circles became illuminated.
The same seven.
Kael's heartbeat quickened.
But the mural continued.
The seven circles began moving.
Not toward the chest.
Toward another point.
A place beneath the earth.
Kael stared.
"They're not returning yet."
Cain looked at him.
"What?"
"The seven."
Kael pointed.
"They're moving toward something else."
"What?"
"I don't know."
Then he saw the final image.
It showed seven fragments surrounding a single empty circle.
And beneath them was the symbol for a door.
Kael stepped backward.
The mural ended there.
The rest of the wall was destroyed.
A sound came from the darkness.
Clink.
Everyone turned.
Another.
Clink.
Metal against stone.
Cain moved forward.
"Who's there?"
No answer.
Kael felt the air change.
Something was approaching.
Slowly.
Footsteps.
One after another.
Then a voice.
Human.
"You're not supposed to be here."
Cain raised his weapon.
A figure stepped into the light.
Association armor.
A Hunter.
Kael recognized him.
One of the three who had disappeared in the northern structure.
Cain lowered his weapon slightly.
"You're alive."
The Hunter looked at him.
"Unfortunately."
Iria moved closer.
"What happened to you?"
The man stared at the murals.
"I went down."
"How far?"
"Far enough."
"Where are the other two?"
He didn't answer.
Cain stepped forward.
"Where are they?"
The Hunter finally looked at him.
"They stayed."
"Stayed where?"
"Below."
Kael watched him carefully.
Something was wrong.
The man's movements were too slow.
His eyes didn't blink enough.
His breathing was irregular.
Kael whispered, "Cain."
Cain looked at him.
Kael shook his head.
The Hunter smiled.
"You noticed."
His voice changed.
Only slightly.
But enough.
Kael's Gate reacted.
The man's body flickered.
For an instant, his face changed.
Then returned.
Cain attacked.
The Hunter disappeared.
The blade struck empty air.
A black shape moved across the ceiling.
Iria fired.
The shape dodged.
Kael opened Heaven's Gate.
Golden light flooded the chamber.
The shape stopped.
For a moment, it appeared clearly.
Human body.
Long limbs.
A distorted face.
One arm seemed covered in black armor.
The other looked almost normal.
Then the shape split.
Two figures appeared.
Cain attacked one.
Iria attacked the other.
Kael summoned a sword.
Heaven's Gate began draining him immediately.
The first figure moved toward him.
Kael blocked.
The impact nearly broke his arm.
He stepped back.
The creature struck again.
Kael dodged.
He cut across its chest.
Black liquid spilled.
The creature screamed.
The sound wasn't human.
The second figure lunged at Iria.
Cain intercepted.
Their weapons collided.
The chamber shook.
Kael felt the Gate draining faster.
Five seconds.
Ten.
He struck the creature again.
It moved unnaturally.
Its body bent backward.
Then sideways.
Kael barely avoided its claws.
"You're fast."
The creature tilted its head.
"You are late."
Kael froze.
"What?"
The creature smiled.
Its mouth stretched too far.
"Late."
Kael attacked.
The sword pierced its chest.
The creature looked down.
Then laughed.
It grabbed the sword.
Kael's eyes widened.
The weapon began disappearing.
Fifteen seconds.
The creature pulled.
Kael released the sword.
The weapon vanished.
The Gate remained open.
Heaven's energy continued draining.
The creature charged.
Kael raised his hand.
Golden energy formed a shield.
The impact sent him sliding backward.
Twenty seconds.
Heaven's Gate flickered.
Kael knew he had seconds.
He summoned a spear.
The weapon appeared.
He thrust.
The creature dodged.
Kael spun.
The spear struck its shoulder.
Black smoke exploded.
The creature staggered.
Twenty-five seconds.
Kael gathered the remaining energy.
He drove the spear into the floor.
A golden shockwave spread through the chamber.
The creature was thrown backward.
The Gate closed.
Kael dropped to one knee.
Cain finished the second creature.
He turned toward Kael.
"You good?"
Kael breathed heavily.
"Ask me later."
The first creature was gone.
Only black residue remained.
The Hunter's body lay on the ground.
Cain approached.
"He was alive."
Kael looked at the residue.
"No."
Cain looked at him.
"He was."
"Not anymore."
Kael stood.
"He wasn't controlling his body."
Cain crouched beside the Hunter.
There was no pulse.
Iria checked him.
"He's dead."
Silence.
Kael looked at the murals.
Something had used the Hunter.
Or something had been using him.
The distinction mattered.
The chamber began collapsing.
Stone fell from the ceiling.
Cain shouted.
"Move!"
They ran.
The passage behind them began closing.
Kael grabbed two researchers.
Iria helped another.
Cain carried the injured Hunter.
They reached the shaft.
But the floor was already breaking.
Kael looked upward.
"Too high."
Cain looked at him.
"Can you open the Gate?"
"For a few seconds."
"Then do it."
Kael opened Heaven's Gate.
Golden light filled the shaft.
He grabbed Iria.
Cain grabbed the others.
They rose.
Ten meters.
Twenty.
The Gate flickered.
Kael gritted his teeth.
Thirty.
Forty.
His vision blurred.
He could feel the weapon limit approaching even though he wasn't summoning anything.
The Gate itself consumed energy.
Fifty.
The entrance appeared.
Kael pushed everyone upward.
They reached the surface.
The Gate closed.
Kael collapsed.
Iria caught him.
"Kael."
"I'm fine."
"You say that too much."
He laughed weakly.
Cain looked at the collapsing ground.
The entire maintenance shaft sealed itself.
Within minutes, there was no sign that they had ever descended.
The Association's cameras had captured everything.
Varen would have enough footage to occupy the research division for months.
But there was one thing they hadn't seen.
As Kael lay on the ground, exhausted, the black key remained inside his closed hand.
He didn't know it was there.
The Association locked down the entire facility.
No one was allowed into the lower levels.
Not Hunters.
Not researchers.
Not even senior officials.
Varen arrived personally.
He walked into the command room and watched the recovered footage.
The mural.
The Hunter.
The creature.
Kael's Gate.
The key.
He watched everything twice.
Then a third time.
"Where is the object?"
The researcher looked confused.
"What object?"
"The key."
"We couldn't find it."
Varen turned.
"You searched Kael's equipment?"
"Yes."
"His clothes?"
"Yes."
"His room?"
"Yes."
"Nothing?"
"Nothing."
Varen stared at the screen.
Kael had collapsed.
The camera showed his hand.
It appeared empty.
Varen paused the footage.
Zoomed in.
There was something.
A dark shape beneath Kael's fingers.
"Enhance."
The image sharpened.
The shape became visible.
Varen stared.
"Find Kael."
Kael woke in the medical wing.
His body felt heavy.
Every muscle hurt.
He looked around.
Iria was asleep in a chair beside the bed.
Kael smiled.
He tried to sit up.
She woke immediately.
"Don't."
"I'm fine."
"No."
Kael sighed.
"You've started sounding like Cain."
"That's because Cain is usually right."
Kael leaned back.
"How long?"
"Six hours."
"What happened to the others?"
"Alive."
"The Hunter?"
Iria's expression changed.
"Dead."
Kael looked toward the ceiling.
"I thought so."
"You fought something using his body."
"Yes."
"What was it?"
Kael closed his eyes.
"I don't know."
Iria watched him.
"Was it connected to the fragments?"
"I think so."
"Think?"
"It didn't react like a fragment."
"What did it want?"
Kael remembered the creature.
Late.
You are late.
He opened his eyes.
"I don't know."
Iria was quiet.
Then she noticed something.
"Kael."
"What?"
"Your hand."
He looked down.
There was a black mark.
Not the fragment.
A thin symbol.
Circle.
Vertical line.
And beneath it—
A tiny key.
Kael stared.
He didn't remember picking it up.
Iria reached toward it.
Kael pulled his hand back.
"Don't."
She stopped.
"Why?"
"I don't know."
The mark disappeared.
Kael opened his hand.
The key was gone.
He stared at his palm.
Nothing.
Iria looked at him.
"Did you see that?"
"Yes."
Neither spoke.
Then the door opened.
Varen entered.
"You're awake."
Kael nodded.
Varen placed a tablet on the table.
"We have a problem."
Kael sighed.
"Another one?"
"Yes."
"What now?"
Varen activated the screen.
A map appeared.
Twenty-nine markers.
Kael frowned.
"What happened?"
Varen enlarged the map.
"Three of the dormant locations have disappeared."
Kael stared.
"What does that mean?"
"We don't know."
"Maybe the readings stopped."
"No."
Varen changed the display.
"These weren't readings."
The map showed three areas marked in black.
"The fragments were detected."
Kael looked closer.
"Then?"
"They're gone."
"Moved?"
"Probably."
"Where?"
Varen shook his head.
"We don't know."
Kael sat up.
"Which ones?"
Varen highlighted three points.
Kael studied them.
One was near a mountain range.
One was beneath an abandoned settlement.
One was deep inside a forest.
They formed a triangle.
Kael stared.
Then he noticed something.
The center of the triangle.
There was nothing there.
But his hand became cold.
Heaven's Gate stirred.
Kael whispered, "There."
Varen looked at him.
"What?"
Kael pointed to the center.
"The fragments didn't disappear."
"Then where are they?"
Kael looked at the three locations.
"They moved."
"To the center?"
"Maybe."
"Why?"
Kael didn't answer.
The sensation grew stronger.
A pulse.
Then another.
The same rhythm as the heartbeat underground.
Boom.
Kael looked at the ceiling.
Boom.
Iria stood.
"Do you hear that?"
Varen frowned.
"Hear what?"
Kael looked at Iria.
"You heard it?"
She nodded.
Boom.
This time everyone heard it.
The medical room trembled.
Varen's expression changed.
"That's impossible."
The heartbeat came again.
Boom.
The Association's lights flickered.
Alarms began sounding throughout the building.
A researcher shouted over the emergency channel.
"Energy surge beneath Sector Nine!"
Varen grabbed the communicator.
"How large?"
"Growing!"
"Source?"
A pause.
Then:
"We don't know."
Kael got out of bed.
Iria grabbed his arm.
"You shouldn't."
"I'm going."
"Kael."
"I need to."
Varen looked at him.
"Why?"
Kael stared at the floor.
"Because whatever is beneath us..."
The heartbeat came again.
Boom.
"...is responding to the fragments."
The entire Association entered emergency lockdown.
Doors sealed.
Elevators stopped.
Security barriers activated.
Hunters moved through the halls.
Awakened trainees were evacuated to the upper levels.
Researchers rushed toward the control center.
Kael, Cain, Iria, and Varen descended toward Sector Nine.
The deeper they went, the stronger the heartbeat became.
Boom.
The walls shook.
Boom.
Dust fell.
Boom.
Kael could feel the Gates.
Heaven's Gate was open inside his mind.
Hell's Gate remained closed.
But something was pressing against it.
Not from outside.
From within.
Kael stopped.
Cain turned.
"What?"
Kael looked down.
"I can feel Hell's Gate."
"Again?"
"Yes."
"Is it opening?"
Kael shook his head.
"No."
"What then?"
Kael struggled to explain.
"It's reacting to the heartbeat."
Varen looked at him.
"Why?"
Kael looked toward the floor.
"I don't know."
They continued.
Sector Nine had been sealed for years.
According to Association records, it contained old storage facilities.
Nothing important.
Nothing dangerous.
But the deeper they went, the less the records matched reality.
The concrete walls ended.
Ancient stone appeared.
The same symbol covered the walls.
Then the corridor opened.
Kael stopped.
The chamber beyond was enormous.
At its center was a circular platform.
Seven black marks surrounded it.
The seven fragments.
Not physically.
Their symbols.
Six were glowing.
One was flickering.
Beyond them were twenty-nine empty circles.
Kael stared.
Then one of the empty circles illuminated.
Everyone froze.
Varen whispered, "Eight."
Kael's heart stopped.
A second empty circle illuminated.
Nine.
A third.
Ten.
Three more lights appeared.
Eleven.
Twelve.
Thirteen.
The researchers panicked.
"Multiple activations!"
"Can we identify the locations?"
"No!"
"Get the map!"
"Already trying!"
Kael stared at the platform.
Seven fragments had awakened.
But the chamber was showing thirteen.
That meant something had changed.
The dormant fragments were beginning to react.
Not one.
Not two.
Six.
Kael looked at Cain.
"This isn't random."
Cain nodded.
"No."
The heartbeat stopped.
The chamber went silent.
Then a voice came from the darkness.
Not the creature.
Not the Hunter.
Not the strange resonance from before.
A human voice.
Calm.
Distant.
Almost impossible to hear.
"Not yet."
Kael froze.
He knew those words.
He had heard them in his dreams.
The voice continued.
"Not yet."
Then the chamber went dark.
Every illuminated circle disappeared.
The Association's systems shut down.
Kael could see nothing.
Then—
A single golden light appeared.
Heaven's Gate.
Behind it, something else appeared.
A black door.
Kael stared.
Hell's Gate.
For the first time, he saw it clearly.
Not open.
Not unlocked.
But present.
The black door stood behind the golden one.
Kael reached toward it.
His hand stopped inches away.
Something was written across its surface.
He couldn't read it.
Yet he understood the meaning.
WAIT.
Kael's breathing stopped.
The black door vanished.
The golden Gate closed.
The chamber returned to darkness.
And somewhere far beneath the Association, something made a sound that was almost a laugh.
Then silence.
For now.
When the emergency lights returned, the chamber was empty.
No creatures.
No fragments.
No strange figure.
Only the thirty-six circles remained.
Seven were bright.
Twenty-nine were dark.
Then one dark circle flickered.
Once.
Twice.
And went out.
Kael stared at it.
He knew what that meant.
The count had not changed.
Not yet.
But somewhere in the world, another fragment had begun to wake.
The gathering was no longer moving one piece at a time.
It was accelerating.
