The abandoned undersea dock was a massive cavern, spanning over 20,000 square meters with a ceiling height of around ten meters. The cavern walls were carved with small alcoves, about a dozen in total.

  Noah casually cleared away the yers of mud and stone covering the floor.

  Docked at the submerged port was a submarine, now rusted and decayed with age.

  Although he had low expectations for any treasure here, Noah didn’t want to dampen his crew’s spirits. “Spread out and search. Let’s see if there’s anything valuable left.”

  The group quickly dispersed, scouring the small alcoves, the wrecked submarine, and areas hidden under stones.

  Kuro removed a rotten wooden door, donned a portable breathing mask with an oxygen tank, and entered one of the smaller caverns. Illuminated by his fshlight, the cavern revealed two rows of bookshelves, though the books were mostly clumped into unusable lumps.

  Fortunately, some books were crafted from special sea-beast hide, resistant to seawater corrosion. Kuro picked one up and leafed through a few pages.

  “Some unknown ancient script… Judging by the illustrations, it seems to be a book about pnts.”

  Gathering all the sea-beast hide books, Kuro counted over two hundred volumes. He also found several ancient maps on the cavern’s desk, depicting the Lost Sea as it appeared centuries ago.

  In another alcove, Lilith discovered carvings on the stone walls, mostly in ancient script, though parts were inscribed in the common nguage, making some of it readable.

  “Sea Circle Calendar 866, March: The Kingdom of Atnt was ambushed by the World Government. The First Fleet of the kingdom was annihited…”

  “May: The World Government unched a Buster Call against the kingdom. Our forces retreated, unable to hold their ground…”

  “August: The isnd of Atn, the kingdom’s capital, was obliterated by a beam from the heavens…”

  “September: The kingdom’s guardian, Pulke, who had been lured away by a World Government ruse, returned to find the kingdom in ruins. Leading the surviving forces, he destroyed 17 Navy ships and killed Admiral Rubio…”

  “October: The Five Elders arrived without warning. Unable to match their strength, Lord Pulke and the remnants of our forces were all but destroyed, and our citizens were sughtered by the Celestial Dragons. In a final act, Lord Pulke awakened the power of his Storm-Storm Fruit, sacrificing his life to unleash a massive hurricane that eradicated all ships in the Atn Sea…”

  “November: I returned to Crab Isnd with six surviving comrades, to carve the history here.”

  Lilith turned to the section carved in ancient script. “Is this a Poneglyph?”

  After reying the information to Noah, he ordered the historical records copied down for future study.

  The rest of the alcoves contained little of interest, though they did uncover some valuable technical documents left by the survivors. The most noteworthy was a set of instructions beled “Atnt Deep-Sea Diving Techniques”, detailing methods for crafting sharkskin swimsuits, artificial gills, deep-sea survival serum, and Sea King pheromone simutors.

  Noah reviewed the technical documents. “These techniques could be incredibly useful for non-Fishman races.”

  While the sharkskin swimsuit was less impressive, the artificial gills, deep-sea serum, and Sea King simutor were advanced, with broad applications.

  Galdino’s wax gills and Ari’s graphite gills were Devil Fruit creations that worked best for them personally; others could only use them for brief periods.

  In contrast, Atnt’s artificial gills were industrial products, usable on a rger scale.

  Simirly, the deep-sea serum was essential for nd-dwellers to dive safely into the deep ocean. Without it, divers faced severe limits in depth and an increased risk of decompression sickness and other dangers.

  The Sea King simutor offered retive safety for divers, especially important in seas filled with monstrous creatures.

  However, Noah noted a fw in the Sea King simutor. Unlike Dr. Vegapunk’s “Sea Cloak,” which rendered its user invisible to Sea Kings, the Atnt simutor made the diver appear like a Sea King. While this could deter marine creatures in the Four Blues, it might attract aggressive Sea Kings in the Grand Line, which could perceive the user as a rival invading their territory.

  Noah ordered his crew to document these technical details.

  After confirming there was no other treasure, they decided not to leave Crab Isnd just yet.

  Noah saw potential in the Lost Sea’s isoted location.

  A massive hurricane created by an awakened Storm-Storm Fruit user had turned this area into a near-impenetrable death zone. Today, only the occasional lost ship would stumble upon the Lost Sea by accident; few ventured here willingly.

  With a radius of about 500 kilometers, the Lost Sea encompassed thirteen isnds. Noah, using Observation Haki, noted these isnds dotted the area, presenting an ideal opportunity to establish a secret base for the Noah family in the South Blue.

  With Frevans’ exiled citizens recovering steadily, Sixis Isnd was nearing its popution limit. The expanding popution also exceeded what could be accommodated on the floating isnds of Sky Isnd. The Lost Sea, with its natural defenses, seemed an ideal new frontier.

  Its violent storms offered a natural shield, and its cluster of isnds provided enough space for expansion.

  The rgest of these isnds was about 11 kilometers in radius.

  Noah set to work, relocating each isnd to the calm “eye of the storm” at the center of the Lost Sea.

  Through Observation Haki, Noah sensed that this calm area had once been the location of the Atnt Kingdom’s capital, Atn Isnd. Now, a deep, seemingly bottomless chasm y on the seafloor—a silent testament to the destructive power of the Heavenly King weapon.

  In the waters surrounding this chasm, Noah chose a shallow, rocky region to secure the isnds, anchoring them firmly.

  Next, he gathered massive amounts of rock and sand from nearby areas, reinforcing the isnds’ foundations to ensure stability.

  Thus, the Storm Archipego, a cluster of five main isnds, was born.

  With this, the establishment of the Storm Archipego Governorate was officially underway.

  Ariopened a wormhole to Sixis Isnd, transporting groups of strong and able workers to begin construction on the new archipego.
