Great Kingdom

Remembered as vast, proud, and formidable, this vanished realm has had every mark of its existence struck from history, and even what it was truly called stays concealed. It stood opposed to the coalition of Twenty Kingdoms that later formed the World Government, and those enemies apparently destroyed it utterly more than eight centuries back, as the Void Century drew to a close. Its fall is precisely what allowed the victors to grip global power and raise the World Government in its place. This same kingdom is why the regime outlaws all research into or translation of Poneglyphs, since the very notion of it endangers their rule.

Professor Clover brought the topic up first, addressing the Five Elders while Ohara stood on the edge of ruin, arguing that the nation's past and ideals were exactly the thing the government dreaded. Vegapunk has since floated the idea that the kingdom wielded technology dwarfing anything the modern age can manage, and though the claim stays unproven, he treats it as evidence that the World Government will erase entire nations to keep the truth buried. Around the same eight-hundred-year mark, the Kouzuki Family created the indestructible Poneglyphs, and the doomed kingdom, sensing both its imminent defeat and the plan to blot out its memory, engraved crucial messages upon them and spread them across the world for those yet to come. Those stones remain the sole surviving witness to the kingdom and the Void Century alike.

What the Poneglyphs have disclosed so far concerns the three Ancient Weapons, each able to devastate on a worldwide scale, raising the possibility that this people had a hand in designing or crafting them. Clover felt sure the kingdom's history held the answers to the age's riddles and named its true name the very key to grasping the Void Century, yet a bullet cut him down before he could utter it. A single inhabitant is known to date, the figure called Joy Boy. Nerona Imu has stated that the Will of D. connects to the Great Kingdom somehow, though the particulars stay hidden.
