The instant the ancient key came into view, the underground city erupted with a sound unlike anything Kael had ever heard.
It wasn't the ringing of bells.
It wasn't the grinding of ancient mechanisms awakening after countless millennia.
It wasn't even the roar of the prison itself.
The sound resembled the slow heartbeat of reality.
Every tower trembled gently as silver light spread through the foundations of the city like glowing rivers beneath transparent stone. Ancient bridges illuminated one after another, while crystal canals shone so brightly that they resembled streams of liquid starlight flowing through the vast metropolis. High above, every bell hanging beneath the cavern ceiling began ringing in perfect harmony, their voices weaving together into a magnificent symphony that echoed across every district. Gardens hidden beneath centuries of dust burst into bloom as silver flowers opened all at once, filling the air with drifting petals that shimmered like tiny stars.
The city wasn't preparing for war.
It was remembering.
Kael staggered as the black mark covering his arm blazed with silver radiance. The ancient symbols spread across his shoulder before reaching his neck, where they slowly intertwined into patterns unlike anything he had seen before. They no longer resembled a curse.
They resembled a language.
A language older than history.
The Traveler remained standing beyond the Watcher, holding the weathered staff in one hand while the ancient key rested quietly upon its tip. Despite the immeasurable distance separating them, Kael could feel the object calling to him. The sensation wasn't physical. It echoed somewhere deep within his soul, awakening memories that had remained untouched even after everything he had recovered.
The First Son slowly lowered his head.
"It still recognizes him."
The Stranger smiled faintly.
"It never forgot."
The Sleeper quietly closed its golden eyes.
"It couldn't."
Far beyond the widening crack, the Watcher's endless black eyes remained fixed upon the key. For the first time since it had appeared, the ancient being's expressionless face showed the slightest hint of change. The stolen smile had vanished completely. Instead, the surrounding darkness began moving in slow circles around its body, as though countless unseen currents had awakened beneath the endless void.
The Traveler noticed.
"So..."
His calm voice drifted gently across the darkness.
"You remember this too."
The Watcher answered immediately.
"I remember losing it."
The words settled over the prison with crushing weight.
Kael stared at the ancient key.
His heartbeat quickened.
Losing it?
The key...
Had once belonged to the Watcher?
The realization shook every person standing upon the observation platform.
General Caelan instinctively reached for his sword before stopping himself. Lyra slowly took a step backward, her eyes never leaving the object resting atop the Traveler's staff. Even Aren, who usually found a joke in every impossible situation, remained speechless.
The Traveler quietly shook his head.
"No."
His gray eyes remained calm.
"It never belonged to you."
The Watcher's gaze never shifted.
"It was taken."
"It was forged."
"It was stolen."
"It was earned."
Every answer came without hesitation.
The conversation felt less like an argument and more like two beings repeating words they had exchanged countless times before.
Kael suddenly realized something.
Neither of them was trying to convince the other.
Both already knew the truth.
Another memory surged through him.
This one arrived with overwhelming clarity.
Warm sunlight poured through an enormous forge built into the side of a mountain overlooking the ancient capital. Rivers of molten silver flowed through carefully carved channels while dozens of master craftsmen worked beneath towering bells that rang softly with every strike of their hammers. Unlike ordinary forges, there was no smoke. Instead, countless tiny particles of light drifted through the air like glowing snow.
At the center of the forge stood the four brothers.
Around them...
Seven master smiths.
The Traveler stood beside an elderly woman whose hands glowed with brilliant silver light.
She held a single lump of dark metal unlike anything Kael had ever seen.
It absorbed light.
Sound.
Even warmth.
The elderly smith smiled.
"This came from beyond the first sky."
The Stranger stepped closer.
"Will it survive?"
The woman laughed quietly.
"It survived before stars existed."
The First Son folded his arms.
"And after?"
Her smile slowly disappeared.
"We'll find out."
Kael's ancient self gently placed both hands upon the dark metal.
Silver light flowed from his palms.
The Fourth Brother followed.
Then the First Son.
Then the Stranger.
Finally...
The Traveler rested one hand beside theirs.
Five streams of light merged.
Gold.
Silver.
White.
Deep blue.
And a color Kael could not describe.
The impossible metal slowly changed shape beneath their touch.
It became...
A key.
The elderly smith looked toward the five guardians.
"Remember."
Her voice echoed gently throughout the forge.
"This key cannot close the Door."
Everyone looked at her.
"It can only choose..."
She carefully lifted the completed key.
"...who carries the burden."
The memory shattered.
Reality returned.
Kael inhaled sharply.
The key wasn't a weapon.
It wasn't a seal.
It was...
A responsibility.
The Traveler immediately noticed Kael's expression.
"You remembered the forging."
Kael nodded slowly.
"The key chooses."
The Traveler smiled.
"No."
He gently lowered the staff.
"The one who carries it chooses."
Silence followed.
The distinction mattered.
The Sleeper suddenly looked toward the deepest part of the underground city.
Its calm expression changed.
The First Son noticed immediately.
"What is it?"
The ancient being slowly opened its eyes.
"The First Lock."
The words echoed through the prison.
"It has awakened."
The underground city trembled.
Not from the Watcher.
Not from the Door.
From below.
Far beneath the elegant streets...
Far beneath the crystal rivers...
Far beneath even the prison itself...
Something enormous shifted.
The entire city rose several meters before settling again as unimaginable mechanisms hidden beneath its foundations slowly began moving. Ancient gears larger than mountains turned for the first time in thousands of years. Silver pillars emerged from the abyss surrounding the city while forgotten runes ignited across every wall, bridge, and tower.
Kael felt the vibration beneath his feet.
It wasn't random.
It was rhythmic.
Like the turning of an impossibly ancient machine.
The Traveler slowly looked toward him.
His warm expression disappeared.
"The prison has accepted your return."
A long silence followed.
"But..."
He looked at the ancient key resting upon the staff.
"...the Locks will not."
Far below the underground city...
Something knocked once.
The sound echoed upward through the foundations.
Not loudly.
Not violently.
Patiently.
As though whatever lay beneath the First Lock had finally realized...
Its keeper had come home.
