The heartbeat echoed through the Vault.
THUMP!
The stars above flickered.
Some brightened.
Others went dark forever.
The mountain groaned as ancient formations buried beneath the Nine Peaks awakened one after another.
Across the academy, every bell rang simultaneously.
No one struck them.
They rang on their own.
Inside the Vault, no one moved.
The name still hung in the air.
Elyndor.
Kai had never heard it before.
Yet it filled him with an indescribable feeling.
Not fear.
Not joy.
Loss.
A deep, aching sense that something precious had been forgotten.
Ashren slowly regained his footing.
His normally composed face had gone pale.
"You should not have spoken that name."
The figure inside the crystal lowered its eyes.
"I didn't intend to."
"It escaped."
The old wanderer picked up his cracked staff.
"Even after all this time..."
"...its name still forces its way into existence."
Kai looked from one ancient figure to the other.
"Will someone finally explain what's happening?"
Ashren gave a bitter laugh.
"I would."
"The Veil won't let me."
As if proving his words, the moment he tried to continue—
Blood trickled from the corner of his mouth.
Invisible chains wrapped around his wrists for the briefest instant before fading away.
He wiped the blood aside.
"The laws are listening."
The black crystal pulsed.
The blank-faced figure rested a hand against its inner surface.
"You don't need the whole truth."
"You only need the next step."
Kai frowned.
"I'm tired of riddles."
"So was I."
The figure smiled sadly.
"Until I learned..."
"...truth given too early becomes another prison."
The black book floated from Kai's hands once more.
It opened to a page that had been completely blank before.
This time there was a drawing.
Not words.
An image.
It showed four flames surrounding a single door.
Three burned brightly.
The fourth was faint and incomplete.
Beneath the illustration, new words slowly appeared.
The Four Heartbeats do not belong to four people.
Kai's breath caught.
More words formed.
They belong to one journey.
The ink stopped.
Silence.
Ashren stared at the page for a long time.
"So..."
"The Archive chose to tell him."
The old wanderer quietly nodded.
"It believes the time has come."
Kai looked up.
"What does that mean?"
Neither of them answered.
Another silver chain snapped.
The black crystal cracked from top to bottom.
Thin lines of darkness spread across its surface.
The figure inside closed its eyes.
"My prison is ending."
"It was never meant to last forever."
Suddenly—
A brilliant beam of blue light shot upward from the academy above.
Then another.
Nine beams in total.
One from each peak.
They converged directly above the Vault.
Master Caelum's voice thundered through the mountain.
"The Nine-Peak Grand Formation is active!"
"All disciples evacuate immediately!"
The entire academy shook.
Seris tightened her grip on her sword.
"They're sealing this place."
Ashren shook his head.
"No."
"They're buying us time."
The blank-faced figure looked directly at Kai.
"When the crystal breaks..."
"I will disappear."
Kai instinctively stepped forward.
"Then let me free you."
The figure's smile returned.
"You misunderstand."
"I am not the one imprisoned."
Kai froze.
"What?"
The figure slowly raised one finger.
It pointed...
Not at the crystal.
Not at the chamber.
Upward.
Toward the endless sky of stars above the Vault.
"The prison..."
"...is the Ninth Era itself."
Before anyone could speak—
The crystal exploded.
Not outward.
Inward.
It folded into a single point of darkness no larger than a grain of sand.
The figure was gone.
Only a tiny silver star remained, floating where it had stood.
It drifted gently toward Kai.
The moment it touched his chest—
The Coreless Heart erupted with silver light.
Countless visions flooded his mind.
A staircase reaching beyond existence.
A door with four circles.
A city swallowed by white fire.
Four silhouettes standing before something vast.
Then—
One silhouette turned around.
Its face remained hidden.
But its voice was unmistakable.
It was Kai's own voice.
It whispered:
"When you reach the final door..."
"...don't let me open it."
The visions shattered.
Kai collapsed to one knee, gasping.
The mountain roared.
The Nine-Peak Formation above them cracked.
One of the blue beams flickered.
Then went out.
Master Caelum's horrified voice echoed again.
"Impossible!"
"Something is attacking the formation from outside!"
Ashren slowly lifted his head.
His expression became grim.
"They're here sooner than I expected."
Kai forced himself to stand.
"Who?"
Ashren looked toward the ceiling, where the first fractures were spreading through the stone.
Not the Veiled Court.
Not the Keeper.
Not the Hollow Judge.
"This time..."
"...the ones who remember the world before the First Era."
The ceiling burst apart.
A massive hand reached into the Vault—not to attack, but to pull reality itself open like a curtain.
Beyond the tear was not another world.
It was an endless sea of stars.
Standing upon those stars were three silent figures, each wearing a featureless white mask marked with a single black star.
The one in the center took a single step forward.
Then, in a calm voice that carried across the entire Vault, it spoke.
"Kai."
"Come home."
