Location: Serpent Trench – Western Grand Line (50,000 meters deep)
"The sea does not forget.
Only the world pretends it did."
— Rayleigh
🌊 The Descent Begins
Beneath the calm of the ocean, a chasm split the world's crust. A vertical drop so steep, so dark, it was said no sunlight had ever kissed its deepest floor.
Serpent Trench.
The Oro Jackson approached carefully, sails down, paddles retracted. The crew wore reinforced Sea Prism gear, courtesy of Scopper Gaban's tinkering. Toni stood at the edge of the diving capsule—his hands gripping the hilt of Frostbrand and his Mythblade both.
Roger smiled as he patted the hatch.
"Down there is the oldest truth I ever saw."
"Time to see if you're brave enough to look back."

Kael glanced at the screen.
"You sure you want to go alone?"
Toni looked at him, smiled faintly.
"No. But I need to."
🧭 50,000 Meters Below
The diving pod breached the lightless zone.
Dark. Absolute.
Then—the Eye opened.
Not a beast. Not a creature.
A massive circular structure, buried in the trench wall, shaped like an iris—its center a rotating gear of glass and stone, 100 meters wide.
Toni whispered,
"It's a memory recorder."
The pod docked. He stepped out.
🌀 Inside the Eye
A hallway spiraled inward, decorated in symbols older than Poneglyphs. As he touched one, the world shifted—
📽️ Vision: The First King
Toni stood in a white hall, not physically—but in memory.
A tall man in a gold-black cloak addressed seven shadowed figures.
"We must seal the timeline. The Sea of Kings is diverging."
"Our last weapon—the Mythblade Protocol—will survive in memory alone."
The vision blurred—then a glowing crystal-like blade was embedded in a massive machine shaped like an eye.
"Let the next myth rise."
Toni screamed as his own Mythblade vibrated uncontrollably.
⚔️ Guardian Awakes – The Drowned One
A roar shattered the silence.
From the trench wall rose a beast: half-machine, half-flesh, its skull crowned in coral and its spine trailing rusted blades. It had no eyes—just one core, glowing blue.
"Initiating purge of unstable heir," it growled.
❗ Boss Fight Initiated: Drowned One – Guardian of the Eye
Toni leapt forward, blades drawn.
"Form XV – Crimson Frostfall!"
He danced through water and fire, each slash slowing the machine's systems, while bursts of rebirth flame stopped its corrosion blasts.
The fight raged across submerged tunnels.
Until finally—
"Form VIII – Twin Horizon Drive!"
A cross-slash of memory and fire split the Guardian in half.
It collapsed into the trench, eyes dim.
🧠 The Eye's Core – Awakening
The Eye opened fully.
Inside, a mirror formed—not glass, but memory.
Toni saw himself… older. Standing beside Shanks. And behind them—Ace, alive.
And then another figure—Roger, bloodied, smiling.
"The Mythblade must choose who sees the truth."
"You are its heir now."

⚓ Return to the Surface
Toni surfaced slowly, pale and quiet.
Roger stood waiting. He didn't speak—just nodded.
Rayleigh asked, "What did you see?"
Toni answered quietly.
"The world ended once."
"They rewound it."
"And now it's happening again."
