The knocking echoed through the fortress.
Once.
Twice.
Three times.
Each impact seemed to vibrate through the stone beneath their feet.
Then silence returned.
No one moved.
No one spoke.
Amara stared at the floating image of the black door.
The Seventh Lock.
Somewhere beneath them.
Waiting.
The Keeper remained motionless.
Its silver mask reflected the golden flames dancing along the walls.
"What is behind the door?" Amara finally asked.
The Keeper did not answer immediately.
For several long seconds, the hall remained silent.
Then—
"Truth."
The single word echoed through the fortress.
Amara frowned.
"That's not an answer."
"No," the Keeper agreed.
"It is."
The young man groaned.
"Why does everyone ancient speak like this?"
To Amara's surprise, the Keeper tilted its head.
"Because truth rarely survives simple explanations."
The young man opened his mouth.
Then closed it again.
Apparently he wasn't sure how to argue with that.
Kael stepped forward.
"We don't have time for philosophy."
The Keeper turned toward him.
"No."
Its voice became quieter.
"We have less time than you believe."
The golden flames suddenly flickered.
Dark shadows stretched across the hall.
The image of the black door trembled.
For a brief moment, Amara thought she saw a silhouette standing behind it.
Watching.
Waiting.
Then it vanished.
The Keeper raised one hand.
"The lock lies below."
The floor beneath them began to glow.
Ancient symbols ignited across the stone.
A circular platform emerged from the center of the hall.
Dust drifted through the air as mechanisms older than kingdoms awakened.
The platform slowly descended.
A path.
Leading downward.
Far downward.
Into the heart of the First Ruin.
The young man stared into the darkness below.
"I have a feeling I'm going to hate this."
"You will," Kael said.
"Good. Glad we're all prepared."
Despite everything, Amara almost smiled.
Then the platform shuddered.
And began descending.
The fortress swallowed them.
The golden hall disappeared above.
Darkness surrounded them.
Only the glowing symbols beneath their feet provided light.
Down.
Deeper.
Further.
The descent seemed endless.
The deeper they traveled, the stranger everything felt.
The air grew heavier.
Older.
Like descending through layers of history itself.
Amara could feel memories buried in the stone around them.
Ancient emotions.
Ancient fear.
Ancient hope.
The First Ruin wasn't merely a place.
It was a monument.
A scar.
A wound left on the world.
Eventually, the platform stopped.
A vast chamber stretched before them.
Amara's breath caught.
The room was enormous.
Far larger than seemed possible.
Ancient pillars rose into darkness.
Rivers of silver light flowed through channels carved into the floor.
And at the center—
A tree.
Silence filled the chamber.
The tree towered above everything.
Its trunk was black as midnight.
Its branches stretched toward the unseen ceiling.
Silver leaves glowed softly in the darkness.
Beautiful.
Impossible.
Alive.
The young man stared.
"What is that?"
Kael looked almost shocked.
The Keeper spoke quietly.
"The First Root."
Amara stepped closer.
The moment she did, a strange warmth spread through her chest.
The pull she had been feeling.
The call.
It was stronger here.
Much stronger.
It was coming from the tree.
Not the door.
The tree.
The realization unsettled her.
She reached out.
The moment her fingers touched the bark—
The world vanished.
Light exploded around her.
A thousand voices whispered simultaneously.
A thousand memories flooded her mind.
Cities rising.
Kingdoms falling.
Wars raging.
Stars moving across unfamiliar skies.
Then she saw him.
The Hollow King.
Not imprisoned.
Not trapped.
Free.
Standing beneath this very tree.
His silver eyes lifted toward her.
Not surprised.
Not confused.
As though he had always known she would see this moment.
The vision shifted.
Another figure appeared beside him.
A woman.
Seraphine.
Younger.
Alive.
The two stood facing each other beneath the glowing branches.
Not enemies.
Not allies.
Something more complicated.
Then another figure entered the memory.
A third person.
Their face hidden.
Their presence impossible to ignore.
The moment they appeared, the memory began breaking apart.
Cracks spread through the vision.
Darkness consumed the edges.
The hidden figure turned toward Amara.
And smiled.
A terrible smile.
Recognition flashed through her.
Not because she knew the face.
Because she knew the feeling.
The laughter.
The one from beyond the prison.
The same presence.
The third prisoner.
Amara gasped.
The vision shattered.
She stumbled backward.
Reality slammed back into place.
The chamber.
The tree.
The others.
Kael caught her before she fell.
"What happened?"
Amara struggled to breathe.
"I saw them."
The Keeper became very still.
"Who?"
"The Hollow King."
Silence.
"Seraphine."
The silence deepened.
Then Amara looked directly at the Keeper.
"And the third prisoner."
Every golden flame in the chamber extinguished instantly.
Darkness swallowed the room.
For the first time, genuine alarm entered the Keeper's voice.
"You saw its face?"
"No."
The flames slowly reignited.
Relief.
Actual relief.
The Keeper stepped forward.
"Describe what you felt."
Amara hesitated.
Then answered.
"It wasn't angry."
Nobody spoke.
"It wasn't trapped."
The chamber seemed to grow colder.
"And it wasn't afraid."
Kael's expression darkened.
The young man looked between them.
"What does that mean?"
The Keeper lowered its head.
Its silver mask reflected the glowing tree.
Then it spoke words that froze everyone in place.
"It means the third prisoner wanted to be sealed."
Silence.
Absolute silence.
Amara felt her heartbeat quicken.
That made no sense.
None at all.
The prison.
The locks.
The seals.
Everything had been built to keep things inside.
Why would someone willingly enter it?
The Keeper's voice became quieter.
"He was not imprisoned."
A pause.
Then—
"He was hiding."
The silver leaves above them began trembling.
The First Root shuddered violently.
A deep crack echoed through the chamber.
Then another.
And another.
Everyone looked upward.
The tree's glowing trunk was splitting open.
Something inside was waking.
Something buried at the heart of the First Ruin.
The Keeper took a step back.
For the first time since they had met it—
Fear entered its voice.
"The lock has found you."
The crack widened.
Silver light erupted from within the tree.
Ancient power flooded the chamber.
And deep inside the opening—
A black door slowly began to emerge.
The Seventh Lock had awakened.
And it knew Amara was here.
