For several seconds, no one moved.
The forest had gone silent.
Even the damaged hunters of the Hollow Crown seemed to forget their injuries as they stared at the man standing beside the entrance to Cabin Zero.
Lucan Valerius.
The name settled over the clearing like a blade.
Arin had never heard it before.
Not once.
House Valerius preserved everything.
Birth records.
Marriage contracts.
Bloodline histories stretching back hundreds of years.
Portraits of dead heirs covered the estate’s western gallery. Even disgraced relatives remained in the family archives, though their names were often written smaller than the others.
A firstborn son could not simply disappear.
Yet Lucan’s face carried too many familiar details to dismiss.
The line of his jaw resembled Duke Aldric Valerius.
The shape of his eyes belonged to the older family portraits.
Even the way he stood—with his shoulders relaxed while everyone around him prepared for violence—felt painfully familiar.
It was the same posture Arin’s father used when he believed the outcome had already been decided.
Serena’s fingers tightened around Arin’s sleeve.
"He is lying."
Her voice lacked conviction.
Lucan heard it.
"Am I?"
He turned toward her.
"You served Lady Elara for nine years. Surely you remember the sealed northern nursery."
Serena’s face changed.
Only slightly.
But Arin noticed.
Lucan smiled.
"The room no one was permitted to enter."
"That proves nothing," Serena said.
"The portrait behind the false wall?"
Her grip weakened.
"The silver cradle?"
"Stop."
"The bloodstains beneath the eastern window?"
"I said stop."
Lucan’s smile vanished.
For the first time, cold anger entered his face.
"You were not there when they removed me."
Serena looked as though he had struck her.
Arin stepped between them.
"Enough."
Lucan’s gaze returned to him.
"You believe her before me."
"I believe neither of you."
"Good."
Lucan glanced toward the staircase descending beneath the ruined cabin.
"That may keep you alive."
The old structure continued changing around them.
Wooden walls folded inward and dissolved into motes of light. The floor separated into six triangular sections, each sliding beneath the earth. Metal supports rose where rotting beams had stood moments before.
What remained no longer resembled a cabin.
It was an entrance station.
Circular.
Black.
Built from the same ancient material as Sublevel Nine.
At its center, the stairs led downward into pulsing blue darkness.
The sound below continued.
Thump.
Pause.
Thump.
Not loud.
Yet Arin felt each beat through his boots.
The System window hovered above the entrance.
«LEGACY TRIAL ACTIVE.
CLAIMANTS:
ARIN ELYSIUM.
LUCAN VALERIUS.
ENTRY WINDOW:
08:42.»
The countdown began.
Serena pulled Arin closer.
"You cannot accept this."
"I don’t have a choice."
"You always have a choice."
"Not when losing means surrendering House Elysium."
"Then refuse the arbitration entirely."
Arin raised his Authority Band.
The gray Founder symbol pulsed beside his own.
"System, cancel Legacy Trial."
«REQUEST DENIED.
COMPETING FOUNDER CLAIMS MUST BE RESOLVED.»
"Remove Lucan’s authority."
«REQUEST DENIED.»
"Expel all hostile individuals from the valley."
«REQUEST DENIED DURING ARBITRATION.»
Lucan descended the first step.
The System did not stop him.
Arin watched carefully.
"What happens if only one claimant enters?"
Lucan paused.
A notification answered before he could.
«FAILURE TO ENTER BEFORE WINDOW CLOSES WILL BE TREATED AS FORFEITURE.
ALL FOUNDER AUTHORITY WILL TRANSFER TO REMAINING CLAIMANT.»
Serena swore under her breath.
Lucan looked back.
"There is your choice."
Arin ignored him.
"Warden Unit–03."
The mechanical beast lowered its head.
"If my authority is removed, what happens to my family?"
The Warden’s eyes flickered.
«PRIMARY FOUNDER TRANSFER MAY ALTER FAMILY REGISTRATION.
FAMILY SAFETY CANNOT BE GUARANTEED.»
That settled it.
Lyra was at the mansion.
EVE was protecting her.
But House Elysium’s defenses depended on authority.
If Lucan became the primary Founder, he would not need to break through the city to reach them.
The city itself might open the doors.
Arin turned to Serena.
"You are going to the mansion."
"No."
"That was not a request."
"I am not leaving you here with him."
"You can barely remain standing."
"I can still fight."
"Not against the city."
He looked toward the eight Hollow Crown hunters.
Several had recovered.
The man whose legs had been struck by the Phantom-01 lay against a tree, breathing through clenched teeth. The others were injured but conscious.
Arin lowered his voice.
"If this trial removes the arbitration restrictions, they will move immediately."
Serena followed his gaze.
"You think they will attack the mansion."
"I think they came for the infant and Lyra."
Her expression hardened.
"Then I stay with them."
"Take the Warden."
Lucan laughed softly from the stairs.
"You assume it will obey outside the trial."
Arin looked at the mechanical beast.
"Will you?"
«ACTIVE FAMILY PROTECTION DIRECTIVE REMAINS VALID UNTIL FOUNDER TRANSFER IS COMPLETE.»
"Then guard the mansion."
The Warden hesitated.
Its gaze moved toward the entrance.
«LEGACY TRIAL THREAT LEVEL:
UNKNOWN.
FOUNDER SURVIVAL PROBABILITY:
INSUFFICIENT DATA.»
"I did not ask for a prediction."
The Warden lowered its massive head.
«COMMAND ACCEPTED.»
Serena looked at Arin.
There was fury in her eyes.
And fear.
"You sound exactly like her."
"My mother?"
"She used the same voice whenever she was about to do something reckless."
"Then perhaps you should be used to it."
"That does not make it less irritating."
Arin removed the legacy dagger from his belt.
The one Serena had carried.
The silver-tree crest on its handle shimmered beneath the trial’s light.
He held it out to her.
"Take this."
She stared.
"It reacted to you."
"It came from my mother. You may need it to protect the child."
Serena did not reach for it.
"What will you use?"
Arin looked toward Cabin Zero.
"Whatever is down there."
The countdown continued.
«06:19.»
Serena finally took the dagger.
Her fingers closed around his hand for a moment.
"Do not trust anything that calls you Founder."
Arin thought of EVE.
Cael.
The city.
The System.
Then Lucan.
"That advice came late."
He released the weapon.
The Warden lowered its body, allowing Serena to grip one of its armored plates. She climbed onto its back with difficulty.
Before the beast turned, she looked down at Arin.
"If he truly is your father’s son, he was erased for a reason."
Lucan heard her.
"And Arin was exiled for one."
Serena’s eyes flashed.
The Warden carried her into the forest before she could answer.
Builder-01 followed at a distance, hovering toward the mansion.
The remaining Hollow Crown hunters stayed where they were.
Arin pointed toward them.
"They remain outside."
Lucan continued descending.
"They will not interfere."
"That promise means nothing."
"Then consider it strategy. If I require their help, I have already lost."
Arin looked at the closest hunter.
The woman who had wielded the metal staff was still alive beneath a layer of Warden-crushed earth. One of her companions worked to free her.
"Any of them approach the mansion, and arbitration or not, I will find a way to kill them."
Lucan’s expression remained calm.
"I believe you."
That answer unsettled Arin more than mockery would have.
He approached the stairs.
The moment his foot crossed the threshold, the Authority Band flashed.
«ACTIVE FOUNDER ENTERED.
LEGACY CLAIMANT ENTERED.
EXTERNAL PERSONNEL EXCLUDED.
SEALING CABIN ZERO.»
A barrier formed behind him.
The forest vanished beyond a wall of silver light.
No retreat.
No Warden.
No family.
Only Arin, Lucan, and the darkness beneath the valley.
The staircase descended farther than it should have.
The walls were narrow at first, lined with dark metal and dead control panels. Blue strips illuminated one after another as the two claimants passed.
Lucan walked several steps ahead.
He showed no hesitation.
"You have been here before," Arin said.
"No."
"You knew where the entrance was."
"I knew it existed."
"How?"
"The authority fragment remembers certain things."
Lucan raised his scarred palm.
The Founder symbol pulsed beneath the skin.
"It does not speak in words. It pulls. Warns. Opens doors."
"Where did you get it?"
"I told you."
"From a corpse."
"Yes."
"Whose?"
Lucan glanced back.
"Someone who called himself a Founder."
"Cael?"
Lucan stopped.
The name echoed down the passage.
For the first time since removing the mask, his control cracked.
Only for an instant.
"You met him."
Arin said nothing.
Lucan studied his face.
"Sublevel Nine opened."
"That sounds like concern."
"It is."
"For him?"
"For everyone."
Lucan continued downward.
"If Cael is awake, the city is already further along than we believed."
"You know what he tried to do."
"Destroy House Elysium."
"He claims the city was destroying itself."
"He was right."
Arin watched Lucan’s back.
Too many people had repeated that claim for it to be dismissed.
"What exactly does that mean?"
Lucan gave no immediate answer.
The stairs ended.
A vast circular chamber opened before them.
Arin stopped.
Cabin Zero was not a room.
It was a buried forest.
Black trees rose from a floor covered in shallow silver water. Their branches reached toward a ceiling so high it vanished into darkness. Thousands of transparent pods hung among those branches like fruit.
Most were empty.
Some were broken.
A few contained indistinct shapes.
At the center of the forest stood a white cabin.
Small.
Simple.
Almost identical to the one that had first appeared when Arin activated Project Elysium.
Smoke rose from its chimney.
Warm light glowed through its windows.
The sight was so ordinary that it felt more threatening than the prison.
The System appeared above the water.
«LEGACY TRIAL: THE FIRST HOME.
PURPOSE:
DETERMINE WHICH CLAIMANT UNDERSTANDS THE FOUNDATION OF HOUSE ELYSIUM.
RULE ONE:
ONLY ONE CLAIMANT MAY LEAVE AS PRIMARY FOUNDER.
RULE TWO:
AUTHORITY COMMANDS ARE RESTRICTED.
RULE THREE:
THE HOME MUST SURVIVE UNTIL DAWN.»
Arin looked upward.
There was no sky.
No sun.
No indication of time.
A final line appeared.
«TRIAL BEGINS WHEN BOTH CLAIMANTS ENTER THE HOME.»
Lucan stepped into the silver water.
Ripples spread from his boots.
Arin followed.
The liquid was warm.
Not water.
Something thicker.
It moved around his ankles as though alive.
The hanging pods reacted to their presence.
Soft lights awakened inside them.
One by one.
Arin saw shadows within.
Small forms.
Children.
Some curled tightly.
Some floating upright.
Most appeared asleep.
One pod contained only a skeleton.
Arin’s stomach tightened.
"The Ark Nursery," he said.
Lucan did not look up.
"A part of it."
"You knew this was here."
"I suspected."
"The infant Serena carried came from one of these pods?"
"Not this chamber."
"Then where?"
Lucan stopped before a broken pod.
Long claw marks covered its inner surface.
"House Elysium had many nurseries."
"How many?"
"Enough to preserve the old world."
"That is not a number."
Lucan looked at him.
"You sound like me."
"I would rather not."
They reached the white cabin.
Its front door stood open.
Inside waited a single room.
Two beds.
A fireplace.
A table set for four.
And a woman seated in the far chair.
Arin’s breath stopped.
She had dark hair.
Pale green eyes.
A narrow face softened by a familiar smile.
She looked exactly as Arin remembered.
Not older.
Not injured.
Not imprisoned.
His mother.
"Elara," Lucan whispered.
The woman looked toward them.
Her eyes filled with warmth.
"My sons."
Arin’s body went rigid.
Lucan went pale.
The door slammed behind them.
«BOTH CLAIMANTS HAVE ENTERED.
LEGACY TRIAL BEGUN.
TIME UNTIL DAWN:
12 HOURS.»
The woman rose.
She crossed the room and touched Lucan’s face first.
He did not move.
His composure vanished completely beneath her hand.
"You grew so much," she said.
Lucan’s lips parted.
No sound came out.
Then she turned to Arin.
Her fingers brushed his cheek.
The warmth felt real.
The scent of orange peel and cedar filled the room.
Memories struck him.
A greenhouse.
A bell tower.
A hand resting over his hair while thunder shook the estate windows.
"You became thin," she murmured.
Arin caught her wrist.
"Who are you?"
Pain entered her expression.
"Arin."
"That is not an answer."
"I am your mother."
"My mother is alive somewhere outside this valley."
"So am I."
He tightened his grip.
"What does that mean?"
The fireplace went out.
Darkness pressed against the windows.
Something scratched the outer wall.
Once.
Twice.
Then from beyond the cabin came the sound of many small hands dragging across the wood.
The woman’s expression changed.
Fear replaced tenderness.
"They found us."
Lucan turned toward the windows.
Shadows moved between the black trees.
Hundreds of them.
Child-sized.
Wrongly shaped.
The System’s voice echoed through the cabin.
«THE FIRST HOME MUST SURVIVE UNTIL DAWN.
EACH CLAIMANT MAY SAVE ONLY ONE.
CHOOSE CAREFULLY.»
The table shifted.
Four chairs remained.
Arin.
Lucan.
The woman wearing their mother’s face.
And a fourth figure seated with its back to them.
Small shoulders.
Dark hair.
A wooden rabbit resting in its lap.
Arin’s blood turned cold.
The child slowly turned.
Lyra looked up at him with tears in her eyes.
"Big Brother," she whispered.
Outside, the first window shattered.
