Livia’s pendant stopped both Ape Titans at once.
Until that moment, Cassian had believed nothing could control them without Rome’s armor.
The first creature stood beside the shattered arena gate, broken bronze restraints hanging from its enormous wrists.
The second remained closer to the wall, pieces of Varro’s control harness still wrapped around its shoulders.
Both creatures had been roaring only seconds earlier.
Then Livia opened the pendant her father had left behind.
Silence.
The change was immediate.
She held the small bronze disc in front of her.
Three narrow lines were engraved across its surface.
The first Ape Titan lowered its head.
Then the second did the same.
Cassian stared.
“Don’t move.”
Livia barely heard him.
She was looking at the creatures.
Not at their teeth.
Not at their enormous hands.
At their eyes.
They were watching the pendant.
No.
They were remembering it.
Above the arena, thousands of spectators had fallen quiet.
Governor Varro stood at the imperial balcony surrounded by guards.
The confidence he had displayed earlier was gone.
“Take it from her!”
Nobody moved.
Varro turned toward the soldiers.
“Did you hear me?”
Still nobody stepped onto the sand.
Two Ape Titans now stood between the soldiers and Livia.
Cassian almost smiled.
“I think they heard you.”
Varro’s face tightened.
“Kill him.”
The archers lifted their bows.
The first Ape Titan roared.
Every bow lowered again.
Livia looked toward Varro.
“What is this pendant?”
He said nothing.
“My father carried it.”
Still nothing.
“Both creatures recognize it.”
Varro’s jaw tightened.
“That proves nothing.”
Cassian looked toward the second Titan.
“I disagree.”
The armored creature had begun pulling at its damaged harness.
One bronze plate came loose.
Then another.
Cassian stepped closer.
Something was wrong.
The creature was not simply trying to free itself.
It was searching for something.
“Livia.”
She followed his gaze.
The Titan hooked one massive finger beneath a panel near its shoulder.
Metal groaned.
Then the panel broke free.
Something fell into the sand.
A narrow bronze cylinder.
Cassian picked it up.
Varro shouted from above:
“No!”
That single word told Cassian everything he needed to know.
He turned the cylinder over.
A tiny latch ran along one side.
“What is it?” Livia asked.
Cassian opened it.
Inside was a tightly rolled piece of treated leather.
Not parchment.
Leather.
Old.
Covered with faded lines.
He carefully unfolded it.
A map appeared.
Livia stepped beside him.
At first, Cassian thought he understood what he was seeing.
Rome.
The coast.
Military roads.
Provincial borders.
Then he noticed the symbols.
Small black marks scattered across the empire.
Each one looked exactly like the symbol engraved into the Ape Titan’s broken armor.
Cassian frowned.
“Arena locations?”
Livia leaned closer.
“No.”
“How do you know?”
“There’s no arena here.”
She pointed toward a symbol far north of Rome.
Cassian recognized the region.
A mountain territory.
Almost no major settlements.
Another symbol appeared in the eastern desert.
Another beneath the southern coast.
Another near a fortified island.
Cassian counted.
“One.”
Then another.
“Two.”
Livia understood what he was doing.
They continued.
Five.
Nine.
Twelve.
Seventeen.
By the time Cassian reached the final symbol, his expression had changed completely.
“Twenty-three.”
Livia stared.
Twenty-three identical marks.
Twenty-three locations.
And only one was beneath the Roman arena where they were standing.
Cassian looked toward the Ape Titans.
“There are more facilities.”
Varro laughed.
But it did not sound confident.
“You know nothing.”
Livia turned.
“Then explain the map.”
Varro said nothing.
Cassian held it higher.
“Twenty-three locations carrying the same symbol as these creatures.”
The spectators began murmuring.
Varro looked around.
That was when Cassian understood something else.
The governor was not simply afraid of the map.
He was afraid thousands of Romans were hearing about it.
Cassian raised his voice.
“What did Rome build at these locations?”
“Silence!”
“What are they?”
Varro gripped the balcony railing.
Then he looked at the two Ape Titans.
For the first time, he seemed to understand he had lost control of the arena.
His voice dropped.
Three words escaped him.
“There are more.”
Livia froze.
Cassian stared upward.
“More what?”
Varro said nothing.
“Ape Titans?”
Silence.
Livia looked back at the map.
Suddenly each symbol felt different.
Not buildings.
Not arenas.
Creatures.
Cassian whispered:
“Twenty-three?”
Varro finally answered.
“Not every site succeeded.”
Livia’s face changed.
“Succeeded at what?”
Varro looked directly at her.
“Building Rome’s future.”
The first Ape Titan growled.
Livia closed her fingers around the pendant.
“You mean turning living creatures into weapons.”
Varro’s expression remained cold.
“I mean creating something no enemy could defeat.”
Cassian looked at the armor covering the second Titan.
“The collars.”
“Control.”
“The pain mechanisms.”
“Discipline.”
“The arenas?”
Varro smiled.
“Testing.”
The crowd reacted.
Cassian stared at him.
The arenas had never simply been entertainment.
At least not these fights.
They had been experiments.
Every gladiator.
Every beast.
Every impossible confrontation.
Rome had been collecting information.
Which creatures could endure weapons?
Which could follow commands?
Which armor designs survived impact?
Which control mechanisms failed?
And how many trained soldiers were required to stop something like an Ape Titan?
Livia whispered:
“My father discovered this.”
Varro’s smile disappeared.
Cassian turned toward her.
“Drusus.”
She nodded.
“He wasn’t working with arena animals.”
She looked at the map.
“He found the program.”
Varro immediately shouted:
“Your father helped create it!”
Livia spun toward him.
“No.”
“Yes.”
“Liar.”
“He designed the first communication system.”
Livia looked at her pendant.
Varro pointed toward it.
“That symbol wasn’t made for you.”
Her fingers tightened around the bronze disc.
“What was it made for?”
“To identify handlers.”
The answer struck her harder than she expected.
Cassian looked at the two creatures.
“That’s why they recognize it.”
Varro nodded.
“Your father believed trust was more reliable than force.”
“And you disagreed.”
“I improved his work.”
Livia stared at the control armor.
“You tortured them.”
“I made them useful.”
The first Ape Titan slammed one fist into the sand.
Varro stepped backward.
Livia looked at the creature.
Then at the pendant.
Images from childhood began returning.
Her father coming home with scratches across his arms.
Blue pigment on his hands.
Unfamiliar sounds beneath their villa.
The strange rule that she must never enter his underground workshop.
And one night when he woke her before sunrise.
He had placed the pendant around her neck.
“If anyone ever tells you monsters cannot remember kindness, don’t believe them.”
She had been too young to understand.
Now she did.
Livia looked at Cassian.
“My father knew Varro would take them.”
“He tried to give you a way to stop them.”
“No.”
She studied the map.
“I think he gave me a way to find them.”
Cassian looked down.
One symbol had been circled.
Far north.
Near the frontier.
The same region mentioned in the message hidden inside Drusus’s pendant.
THE NORTHERN VAULT.
Cassian pointed.
“This one.”
Livia nodded.
“It’s different.”
The Ape Titan beside them suddenly moved.
Cassian reached for his sword.
But the creature ignored him.
It pointed toward the northern symbol.
Livia stopped breathing.
“You know that place?”
The Titan touched its own chest.
Then pointed at the map again.
Cassian and Livia exchanged a look.
“It came from there,” Cassian said.
The second Titan made a low sound.
Then struck another location on the map.
Eastern province.
Another site.
Livia understood.
“They came from different facilities.”
Cassian looked at all twenty-three symbols.
“If two survived…”
Neither finished the thought.
Varro already had.
That was why he looked terrified.
Cassian turned toward him.
“How many are still alive?”
Varro remained silent.
“How many?”
“Enough.”
The crowd murmured again.
Cassian raised the map.
“Enough for what?”
Varro’s eyes moved toward the imperial box.
For the first time, Cassian noticed something strange.
The emperor’s seat was empty.
It had been empty throughout the fight.
Yet imperial banners surrounded the arena.
Cassian felt cold.
“Varro.”
The governor looked at him.
“Where is the emperor?”
Varro smiled.
A slow smile.
“Preparing.”
“For what?”
No answer.
Then horns sounded outside the amphitheater.
Not arena horns.
Military horns.
Three long notes.
Cassian knew that signal.
Deployment.
The crowd heard it too.
People began standing.
Roman officers moved toward the exits.
Livia stared at the map.
One of the symbols near Rome had a tiny red mark beside it.
Fresh ink.
She touched it.
“Cassian.”
“What?”
“This wasn’t on the original map.”
“How do you know?”
“The leather is old.”
She pointed to the red mark.
“But this ink isn’t.”
Beside the symbol was a date.
Today.
Cassian looked toward Varro.
“What happens today?”
Varro said nothing.
The first Ape Titan roared.
Then the second.
Livia suddenly understood.
The arena had not been the final test.
It had been the last test before deployment.
Twenty-three hidden sites.
Unknown numbers of creatures.
Control armor.
Military roads connecting everything back to Rome.
Cassian looked again at the map.
Some sites carried the Ape Titan symbol.
Others had different marks hidden beneath the folds.
A horned creature.
A wing.
A claw.
His expression changed.
“Livia.”
She saw them too.
The Ape Titans were only one part of the program.
Rome had not been building a single kind of weapon.
It had been creating an entire army of controlled creatures.
Varro had released the second Ape Titan because he believed it was his final weapon.
He was wrong.
It was evidence.
And now that evidence had revealed something far larger than either Cassian or Livia imagined.
Livia closed the map.
“We go north.”
Cassian looked at her.
“To the vault?”
“My father left the pendant.”
She touched the bronze disc.
“He left the map inside a creature he knew would recognize it.”
Then she looked toward the northern symbol.
“He wanted someone to find this.”
The Ape Titans stood behind her.
Free.
Waiting.
Cassian glanced toward the arena exits where Roman soldiers were already gathering.
“If we leave, Varro will send everyone he has after us.”
Livia looked up at the governor.
“Good.”
Varro’s smile disappeared.
She raised the pendant.
Both Ape Titans stood at once.
The amphitheater shook beneath their weight.
For years, Rome had hidden its experiments beneath arenas, fortresses and forgotten provinces.
Now two of those experiments were free.
And the daughter of the man who had tried to stop the program finally possessed the map showing where the rest were hidden.
Varro had whispered only three words.
“There are more.”
But the map revealed the truth was even worse.
There were not merely more Ape Titans.
There were more symbols.
More facilities.
More creatures.
And somewhere inside the Northern Vault waited the answer to what Rome intended to do with all of them.
