Following the faint yet persistent guidance of the World Seed, the Thousand Sunny sailed to the edge of the universe where even the stars seemed sparse and dim. The background radiation here was unusually low, as if everything had fallen into silence, and even time flowed exceptionally slowly.
Finally, they stopped before an absolute Void. Not a nebula, not a void, but something... the concept of "nothingness" itself. In the center of this "nothingness" floated a huge, grotesque "scar" that defied description.
It is not a spatial rift, because it seems to Transcendence the concept of space itself. It is more like a "mark" branded on the origin of the universe, its edges constantly flashing with the light of Chaos and order being annihilated and reborn, and its interior is a bottomless darkness from which even light cannot escape. Just gazing at it makes one's soul tremble, as if confronting an unimaginable trauma at the beginning of the universe.
"This is... the place the World Seed led us to?" Usopp's voice was filled with uncontrollable fear. "What the hell is this?!"
The World Seed within Allen was unusually calm at this moment, even carrying an emotional fluctuation that was almost "sadness" and "longing". It emitted a faint light, resonating extremely slightly with that huge "mark".
"I sense... this 'mark'... is incredibly ancient, older than any prehistoric civilization, older than anything we know..." Allen's voice trembled slightly, overwhelmed by the vast and poignant atmosphere. "It... it seems to be..."
"It is the ' Scar of Origin '." A calm, ancient consciousness, seemingly formed from countless years of sedimentation, resounded directly in everyone's hearts.
Everyone turned around in shock, only to see an old man, draped in a simple robe woven from starlight and with an indistinct face, silently hovering outside the porthole of the Thousand Sunny. He showed no energy fluctuations, as if he had merged with the silent Void.
"Are you... Observers?" Robin asked tentatively. The other person's aura was somewhat similar to that of the Observer Zero, but it was more profound and ancient.
"I am the ' Scar Keeper '," the old man's consciousness responded. "Throughout the long ages, our race has guarded this place for generations, witnessing and recording, but... we will never interfere."
His gaze fell upon the enormous mark. "This is the ' Scar of Origin,' not a wound, but... the mark of 'separation.' It is the umbilical cord severed when our universe separated from the ' Sea of Origin ' and gained independent existence, and it is also the foundation of the barrier."
The mark of separation? The severed umbilical cord of the universe?
The information was so shocking that everyone was unable to process it for a while.
"That ' Shadow of the Other Side '..." Allen immediately thought of the enemy.
"'Shadow'... originates from beyond the 'Trace'." The Scar Keeper's consciousness carried a distant sigh. "When our universe separated from the Sea of Chaos and gained its own unique order and laws, another part... or rather, another possibility, was left behind beyond the 'Sea'. They represent absolute ' Void ' and 'assimilation,' yearning to return to complete Chaos, devouring all orderly existence to fill their own 'void'. This 'Trace' is the final barrier separating us from the 'Other Side,' and also... the only 'coordinate' they can perceive and attempt to cross."
"So, ' Cradle ' refers to..." Nami seemed to understand.
"' Cradle ' refers to this ' Scar of Origin ' itself, and also to our entire universe," said the Scar Keeper. "' The Harvest ' of ' The Shadow of the Other Side ' is an attempt to cross this scar on a large scale, devour all the order of this world, and complete their 'Return.' The ' Seed ' within you are one of the original fragments that stabilize the order of this world. To 'The Shadow,' they are a lighthouse, a signpost, and also... the sweetest bait."
The truth is revealed in the most brutal way. What they face is not a simple invasion from another dimension, but an existential threat from "another side" destined since the beginning of the universe, aimed at devouring everything!
"We must stop them!" Luffy shouted.
The Scar Keeper remained silent for a moment, a complex fluctuation emanating from its consciousness. "Witnessing is our duty. Intervening is your choice. The stability of this scar concerns the survival of this realm. However, the barrier is not eternal; upon it... minute cracks have already begun to appear, which is why the 'Shadow' has been able to infiltrate. Repairing or reinforcing the barrier may slow down the ' Harvest ' process. However, the way to completely resolve this... I do not know either."
He pointed to the enormous mark. "The answer may lie deep within the 'mark,' or perhaps... in your own choices. I will continue to witness."
After speaking, the Scar Keeper's figure slowly disappeared as if it had merged into the Void, as if it had never existed.
Before the Straw Hat Pirates lies the ultimate truth concerning the survival of the entire universe, and an almost impossible task—to repair or reinforce the foundation of the universe, the Scar of Origin.
