The newly formed island was unlike anything seen before. This massive, circular landmass directly above Fishman Island connected the inner and outer seas through eight distinct waterways. These channels branched outward in all cardinal and diagonal directions: east, south, west, north, northeast, southeast, northwest, and southwest.
The Red Line's geography had been radically altered. From a bird's-eye view, this new "Octagon Island" formed a giant circular shape, with eight openings resembling the ancient gates of a mythical fortress. Each gate led to a separate section of land, dividing the island into eight vast regions.
While Logan had no firsthand knowledge of what the ancient "Great Kingdom" looked like, he could imagine its design must have been similar. If it served as the world's center long ago, then its layout likely included extensive waterways that connected all directions, much like this island now. And as the nexus of the four seas, this colossal, ring-shaped landmass seemed perfectly suited for the role.
However, Logan had no interest in forming a new government to rule the world. He knew better than anyone that in a world as vast as the One Piece universe, no single organization could truly govern every island, every person. Logan had read countless novels back on Earth, where a grand, unified ending often portrayed a single world order. But real life, as he'd come to understand through his own adventures, was far more complex.
Unifying the world? He scoffed at the thought. At best, any so-called unification would be a façade, an illusion of harmony. No authority could enforce its will on every far-flung island, nor bring peace and justice to every corner of the globe. Even the individual seas of the past struggled to maintain unity.
He imagined a scenario to illustrate his point: suppose a new regime was founded here on Octagon Island. What if a kingdom in the West Blue faced a pirate invasion and called for aid from this new government? They'd send forces, naturally. But if, while defending the West Blue, an emergency erupted in the East Blue, would Octagon Island dispatch even more troops?
The answer was clear: such a system was unsustainable. If Octagon Island's leaders tried to micromanage every crisis in the world, they'd collapse under the weight of their own ambition.
Instead, Logan's vision was simpler and more powerful—just as the Great Kingdom had inspired others 800 years ago, Octagon Island would lead by example. It would not impose its will but rather shine as a beacon of progress and prosperity. Other nations would see its success and, gradually, seek to emulate its ideals. With time, the model of Octagon Island would ripple out, encouraging change across seas and islands. The transformation wouldn't be immediate; it would take generations, even centuries, to bring about lasting change.
The kingdom of the past had once held this dream, only to be destroyed by the alliance of 20 kingdoms. But now, the Straw Hat Pirates had the strength to revive that vision, creating a new Great Kingdom that would spread hope without conquest or control.
With the Octagon Island fully formed, its lands lay empty and open to those who sought a better life. Logan knew the world was filled with people enduring suffering and hardship, people who would eagerly migrate to Octagon Island given the chance to escape poverty or persecution. All it would take was an appeal to their hearts and minds.
The first to embrace the idea was none other than Monkey D. Dragon. As the leader of the Revolutionary Army, Dragon had liberated countless kingdoms and rescued innumerable civilians. Yet, due to the clandestine nature of his organization, those he saved often led meager lives, constantly on the run. Freedom was their only reward, but for many, it was a freedom spent in hiding.
Dragon's cadres rallied the displaced civilians, working tirelessly to gather them for a new beginning. Three months later, the first wave of immigrants set foot on Octagon Island, their hearts filled with hope.
During this time, Logan also visited Fishman Island to meet with King Neptune and Madam Shyarly. He intended to fulfill Madam Shyarly's prophecy, a vision that had foretold Fishman Island's salvation. Through the power of the floating card, Logan lifted the entire island from its deep-sea home, bringing it to the surface. Now, Fishman Island lay at the center of the sea surrounding Octagon Island, a perfect heart to this new world.
For the Fishman and merfolk, this was nothing short of a miracle. Generations had dreamed of living under the sun, free from the shadows of the deep. News of Madam Shyarly's prophecy spread like wildfire, and Logan became a savior to the Fishman and merfolk, a hero who had turned their deepest dreams into reality.
Not one to miss a story, Morgans, the president of the World Economic News Agency, sensed the immense business potential. Without hesitation, he relocated his headquarters to Octagon Island, and within weeks, news of this groundbreaking new society spread across the world like a storm.
A year later, a wave of migration from every corner of the globe was well underway, especially from the West Blue. The region was plagued by mafia control, with civilians living under the oppressive thumb of crime lords. For them, Octagon Island was a sanctuary, a glimmer of hope amidst a sea of despair.
As word of the island spread throughout West Blue, desperate civilians fled their mafia-controlled lives. Some questioned the wisdom of leaving their homes for an uncertain future, but most found solace in the thought that any place was better than the dark shadow cast by the mafia.
The mafia attempted to retaliate, threatening the migrants and forbidding their departure. But a single, blinding bolt of lightning—Logan's declaration of defiance—struck the heart of the largest mafia family's territory, sinking it beneath the waves. Morgans captured the event in his newspaper, and the message was clear: Octagon Island was protected by powers beyond comprehension.
From then on, no one dared to obstruct civilians seeking refuge. The mafia families, and all those who sought to intimidate the people, were paralyzed by fear. They knew that Octagon Island's guardians wielded a power that could erase them in an instant.
Three years passed, and the Octagon Island Kingdom's foundation had solidified. People from all walks of life had come together, building a society rooted in freedom and equality. Neither Luffy nor Logan sought rulership; instead, they entrusted the position to Nefertari Vivi, the compassionate princess of Alabasta. Her royal lineage and dedication to justice made her an ideal leader for this burgeoning kingdom.
Vivi's popularity among Alabasta's people only grew as she helped oversee the kingdom's construction, and soon, she became the beloved figurehead of Octagon Island's government.
Two years after its establishment, even the Revolutionary Army and remnants of the Marines pledged loyalty to Octagon Island, transforming it into a powerful force for peace.
A decade later, piracy had faded into obscurity. From the heart of Octagon Island, a new order of peace extended across the world. Islands once torn by strife now stood united, and the age-old dream of freedom finally became reality.
This peace was not born from treaties or words but from strength and sacrifice. The world knew that Octagon Island, backed by the Straw Hat Pirates, would protect its values at all costs. The kingdom was a shining core of hope, inspiring all who came to its shores to leave behind the past and embrace a brighter future.
