What happened in the 100-year gap the World Government erased? Who fought whom, and why?
The question
What happened during the 100-year Void Century — and what was the Ancient Kingdom the World Government erased?
Leading theories
Joy Boy’s Great Kingdom was a multi-racial liberation alliance
Fishfolk, Skyfolk, Minks, Giants, Lunarians — led by Davy Jones as king and Joy Boy as champion/pirate-figurehead. The WG-precursor coalition (the Twenty) won by deploying ancient weapons that flooded the world.
The Ancient Kingdom literally sat atop the Red Line
When defeated, the WG shattered/raised the continent to bury it. Sky islands and Fishman Island are remnants of populations displaced upward and downward.
The “Sin” was the Mother Flame / proto-Uranus
Vegapunk’s Mother Flame is a re-discovery of the original WMD that drowned the world.
Resolution
Partially resolved — the erased century is now known to have been a vast war between an advanced ancient kingdom and the 20 kingdoms that became the World Government, though its deepest content stays sealed.
The Void Century is a roughly 100-year span (~900–800 years ago) left blank because all its records were deliberately eliminated, recoverable only through poneglyphs scattered across the world — the crime Ohara was destroyed for studying (Ch. 392 , Ch. 1114 ).
It was a “breathtakingly vast war” between a startlingly advanced ancient civilization and a provisional army of 20 allied kingdoms; the 20 won, became the World Government and the Celestial Dragons, and erased all trace of the loser (Ch. 1066 , Ch. 1115 , Ch. 722 ).
The war “came to a close with the defeat of Joy Boy,” the era’s central figure, born into that advanced kingdom (Ch. 1114 , Ch. 1115 ).
The ancient kingdom’s technology rivaled or exceeded the present — surviving as relics like the Iron Giant Emet, a 900-year-old war-machine with an irreproducible power source (Ch. 1065 , Ch. 1067 , Ch. 1120 ).
The founding ties to the Nefertari line: Queen Lily was the 20th monarch who refused to become a Celestial Dragon and was scrubbed from the record (leaving only 19 weapons at the Empty Throne), and her “liberation of the poneglyphs” scattered the stones worldwide (Ch. 1084 , Ch. 1085 ).
The complete truth has been decoded once — by the Roger Pirates at Laugh Tale, via the assembled poneglyph corpus and the Voice of All Things (Ch. 507 , Ch. 967 ).
Still open: Who the ancient kingdom’s people were, the two warring ideologies, and the meaning of the D. clan within the conflict remain sealed.
Still open: How the newest Elbaf-era revelations — that “Elbaph is D,” that Davy D. Jones was once called “King of the World,” and an army of frozen ancient giants — fit the Void-Century picture is still unfolding (Ch. 1154 , Ch. 1164 , Ch. 1171 ).

A deep-history reveal at God Valley: “Davy D. Jones was once the King of the World” (p. 3, disputed by the entity: “He was never king…”), a “grievance between Mu and Davy,” and a “Davy’s will”/“promise” from the ancient past.

The God Valley manhunt’s grand target — the Davy Clan (Rocks’s bloodline, descendants of Davy D. Jones ) — is “found at long last, after 800 years ,” and “every World Noble is aware of them.” The 800-year span dates the clan’s persecution to the start of the Void Century, tying the Davy bloodline to the lost century’s fallen order.

[!evidence|ch=1154] Ch. 1154 pp. 10–11 — Jarul’s deep-history hooks (Elbaf flashback)
In the 56-yrs-ago Reverie flashback, Chief Jarul relates deep-history hooks to King Harald : a distant “great enemy,” a giant history “sunk under the sea one day,” Elbaf as a long-standing “threat to the rest of the world ,” the captured Galleila Band ancient giants ” taken prisoner abroad), and an “army of giants put on ice and hidden somewhere.” Harald asks whether the World Government was responsible. See Galleila Band , The Galleila Band and the Frozen Army of Ancient Giants .

[!evidence|ch=1148] Ch. 1148
The WG’s insistence on burning Elbaf’s millennia-spanning library — and Ronja ’s line that “the books tell you about places all around the world” — hints the giants’ archive may hold suppressed historical records the World Government fears, a possible Void-Century repository (pp. 3–6, 11–14).
[!evidence|ch=1148] Ch. 1147
The WG’s demand that Elbaf burn its library of “pointless records of the past ” and “Elbaph’s ancient history” (pp. 16-17) reaffirms the government’s standing policy of erasing the historical record — the same motive behind Ohara and the forbidden Void Century.
[!evidence|ch=1148] Ch. 1146 pp. 6–7, 10–11
Gunko states the WG’s motive for seizing Elbaf: a prophecy that “the world as we know it will cease to exist,” that “a small number of humans realized it and warned the world,” and that a “vast war” is coming in which the giants’ allegiance is decisive. The World Government has foreknowledge of an apocalyptic war and is pre-positioning against it. See The Prophesied Vast War And The Giants Allegiance .
Ch. 1144 pp. 2–3 — a 3,000-year “pure science” ruin on Elbaf
A skull-shaped facility that “looks like pure science” has stood in Elbaf’s woods “for at least three millennia,” with “no record of what this building is” even among the giants. On an island coded as pre-modern/Norse, an ancient scientific installation older than giant memory is a candidate relic of the pre-Void-Century world / Ancient Kingdom. See Elbaf’s Ancient Science Facility . (evidence_chapters += 1144. GUARD: the Void-Century / Ancient-Kingdom payoff stays forward.)
Ch. 1138 pp. 13-17 — a Void-Century mural on the Adam tree + the Harley’s three Worlds
(1) Children’s drawings carved into the Treasure Tree Adam ’s fossilized bark are dated 800-900 years ago — squarely within the Void Century — depicting non-giants and inter-racial wars but “never cultural exchange” (pp. 13-14). (2) The Harley ’s full three-World text (pp. 16-17) reads as an encoded history: mankind “touched the forbidden sun,” “Man killed the sun and became god,” “the earth god… shrouded the world in death and darkness.” Physical + textual Void-Century evidence surfacing at Elbaf. (evidence_chapters += 1138. ) See The Harley .
Ch. 1122 pp. 16–17 — a glimpse of Emet’s Void-Century origin
Flashback to Emet ’s Void-Century origin: a child built/befriended the construct and stored “the greatest Haki ” inside it to protect across time — a direct on-page glimpse of an Ancient-Kingdom-era figure and their relationship with the Iron Giant. The child is hat-silhouetted and unnamed (implied Joy Boy — GUARDED). See Iron Giant Emet , Haki .
Vegapunk’s broadcast: “that day is coming!!! … One day, the memories of the Void Century will be recalled” (pp.5–6). A winged elder recalls “there used to be a land of gods up there!! Atop the Red Line…” (p.6). The WG is framed as seeking the obliteration of the “last descendants of rare races.” (pp. 5–6)
Ch. 1120 pp. 12–15 — a Void-Century combatant speaks: “a war 900 years in the past… from only one side”
The reawakened Iron Giant — explicitly “a 900-year-old weapon ” (p. 15) — speaks as a Void-Century combatant: “It would be foolish to hear about a war 900 years in the past from only one side… History requires a multifaceted approach to understand entirely” (pp. 12–13). Confirms a two-sided suppressed war and that ancient war-machines from the lost kingdom survive and recognize Joy Boy . (evidence_chapters += 1120; deeper Void-Century content GUARDED — forward.) See Iron Giant Emet , Joy Boy Identity , The Iron Giant Emet Holds An Unfired Power It Will Use When The Time Is Right .
Ch. 1119 — the Void-Century iron giant is named “Emet” and carries a time-gated directive
The Void-Century iron giant is named Emet and shown to carry a deliberate, deferred directive — built/instructed to act “only when the time is right ” (flashback, p. 13). Evidence that the Ancient Kingdom era left purpose-built constructs with time-gated missions aimed at a future moment. Who set the timer is GUARDED — forward. See Iron Giant Emet , Emet Was Instructed To Act Only When The Time Is Right .
Ch. 1117 pp. 14–15 — the Five Elders confirm the iron giant attacked Mariejois 200 years ago
Witnessing the reactivated iron giant (Iron Giant Emet ) fight them, the monster-form Gorosei recognize it on sight: “it’s the iron giant… that attacked Mariejois 200 years ago!! ” Re-asserts the Ch. 1067 exposition in the present, with the apex of the WG personally identifying a Void-Century war-machine reawakened on Egghead . (Content/purpose stays sealed — forward.)
Ch. 1115 — Vegapunk reconstructs the era “from a handful of poneglyphs”
Vegapunk reconstructs the era “from a handful of poneglyphs”: 900 years ago the conflict was “a breathtakingly vast war” between two ideologies (pp. 3–4); the civilization was “startlingly advanced,” its weapons un-replicable even by him (p. 5); the war “came to a close with the defeat of Joy Boy 20 kingdoms known as the Alliance ” — Joy Boy’s enemy (pp. 3–4). There were “a number of continents we know nothing about,” now sunk (p. 14). See Celestial Dragons , Joy Boy Identity .
Ch. 1114 pp. 11-15 — Vegapunk names the Void Century on the open broadcast
The Void Century is publicly named for the world: a “completely and entirely blank” span from ~900 to ~800 years ago , “because all records from this time were eliminated ,” recoverable only through “poneglyphs scattered across the world ” (pp. 11-12). The era’s protagonist was Joy Boy 20 kings… created the world ” (p. 12).
Ch. 1095 p. 8 — the Buccaneers’ ancient “grave crime against the world”
The Buccaneers Buccaneer , The Buccaneers Committed A Grave Crime Against The World .
Ch. 1086 pp. 9, 13 — Imu was one of the original 20 founders
St. Imu of the Nerona Dynasty is placed “among the first 20 who created the world” ~800 years ago (p. 13, Sabo ’s deduction) — directly tying the hidden World Government sovereign to the twenty founding monarchies of the Void-Century close. The Gorosei call the present operation the conclusion of “this ancient battle” (p. 9). (evidence_chapters += 1086; involves += Families/Nerona. Deeper Void-Century content stays sealed — forward.) See Imu Identity , Nerona , Means To Create Everlasting Life Exist In This World .
Ch. 1085 pp. 3–4 — origin of the scattered poneglyphs: Queen Lily’s 800-yr-old “mistake”
Imu Queen Nefeltari D. Lily ’s “great mistake of 800 years ago” — the liberation of the poneglyphs that scattered the stones across the world (“the loathsome relics… would not have been scattered… if not for Lily’s mistake on that fateful day”). Imu raises whether it was a genuine mistake “or was it planned ?” — first on-page account of why the poneglyphs are distributed worldwide, tied to a Void-Century-era Alabastan queen. (Void-Century CONTENT/Lily’s motive stays sealed — forward.) Cross-link Poneglyph , Queen Lilys Mistake Scattered the Poneglyphs 800 Years Ago .
Ch. 1084 — the WG founding restated; the 20 kings, the missing 20th, Queen Lily (Reverie flashback)
The WG-founding lore is expanded on-page (pp. 6–9): ~800 years ago 20 kings created the World Government and the Empty Throne Queen Lily of the Nefertari alone refused to become a Celestial Dragon and returned to Alabasta — leaving only 19 weapons at the throne and her name scrubbed from the record. Cobra surfaces an 800-year-old Nefertari letter and asks “What is the D?”. (evidence_chapters += 1084; involves += Nefertari D Lily. Deeper Void-Century content stays sealed — forward.) See Will of D , Imu Identity .
Ch. 1078 — studying the Void Century is a capital offense (Egghead)
The single report that “Dr. Vegapunk is studying the Void Century ” (p. 10) is enough for the WG to escalate from CP5 → CP7 → CP8 → CP0 → a Five-Elders /Kizaru war deployment — reaffirming that Void-Century research is treated as the world’s gravest crime.
Ch. 1076 p. 11 — Vegapunk’s secret poneglyph research has leaked to the WG (Egghead)
Vegapunk confirms he has been secretly researching poneglyphs at Egghead , and the World Government has discovered it (“There shouldn’t have been any room for the government to find out”, p. 11) — triggering CP0 ’s seven-Vegapunk assassination order and a fleet of over 100 ships converging on the island. His pursuit of the True History is now an active liability. See CP-0 , A Marine Fleet Of Over One Hundred Ships Sails For Egghead .
Ch. 1068 — a living scientist reverse-engineering Void-Century power (Egghead)
Vegapunk states his research goal is the ancient energy “that gave [it] strength” — the power source that “moved this machine soldier” (the 900-year-old buried iron robot from Ch. 1065 ) — and that he digs into “that forbidden history” “in carrying on my friend’s will.” A living scientist actively reverse-engineering Void-Century-era technology. See Iron Giant Emet , Vegapunk Final Message and Sinking World .
Ch. 1067 pp. 9–11 — a Void-Century war-machine with an irreproducible power source (Egghead)
The buried iron giant (“the legendary iron giant” ) that attacked Sacred Mariejois ~200 years ago was built 900 years ago — inside the Void Century. Its “dynamic power source ” is the one thing even Vegapunk cannot re-create: “in the past, they had a power strong enough to rewrite everything we know about the world today .” Robin ties the 200-years-ago attack to the era “when fish-man discrimination became a big issue” (p.10). Direct on-page evidence that the lost age wielded world-altering technology/energy. See The Iron Giant Attacked Mariejois With A Lost Ancient Power Source , Iron Giant Emet .
Ch. 1066 — the Void Century reframed as a war (Egghead)
A Vegapunk satellite reframes the Void Century as “the history of a war ” between an advanced ancient civilization (proven via a “certain machine” — a Poneglyph-class artifact) and a coalition of 20 kingdoms that won, became the World Government, and “erased all traces of it from history” (pp. 2–4). Ohara’s deciphered conclusion survives on Elbaf and in Vegapunk ’s brain (he read the entire rescued library). (evidence_chapters += 1066. The DEEPER Void-Century content/identities stay sealed — forward; record only what the page states.) See True History Ohara Was Killed For , Dragon .
Ch. 1065 pp. 18–19 — Egghead’s “future” tech is the PAST; a 900-year-old advanced kingdom + a surviving iron giant
On Egghead , the Vegapunk satellite Shaka reveals that the island’s “super-future” technology is in fact the past — “there was once a kingdom just as highly advanced as this … that actually existed 900 years ago ,” and “Egghead wasn’t the only one” (p. 18-19). A surviving colossal ancient iron robot from 900 years ago is unearthed in Vegapunk’s scrap heap (p. 19). First on-page evidence that the Void-Century Ancient Kingdom was technologically advanced (rivaling/exceeding the present), and that physical relics of it survive. (evidence_chapters += 1065. Robot left unnamed — its name/purpose/identity stays forward; Void-Century CONTENT stays sealed.) See Egghead Tech Is The Past — An Advanced Kingdom Existed 900 Years Ago , Iron Giant Emet , Vegapunk .
Ch. 1055 pp. 6–7 — the submerged ancient Wano (~800 years ago)
Through a seafloor viewport in Sukiyaki ’s chamber, Robin and Law see the Wano of ~800 years ago — a different, now-submerged country with an enormous Fuji mountain. Its lowland towns flooded and were abandoned; walls grew and new land was built up the mountainside into today’s Wano . Visual confirmation of a Void-Century-era catastrophe/transformation of Wano, tying the closed country to the suppressed history. See Wano’s Sealed Borders And The Awaited Figure , Ancient Weapons .
Ch. 1043 pp. 16–17 — Joy Boy’s return dated to “the first time in 800 years”
Zunisha dates Joy Boy’s presence to “the first time in 800 years” (p.16–17) — re-anchoring Joy Boy and the drums of liberation to the Void-Century timeframe, and confirming the millennium-old elephant as a firsthand witness who remembers him. (Void-Century CONTENT stays sealed — forward; the Nika/Sun-God naming is the next chapter.) See Drums of Liberation , Zunisha’s Ancient Crime .
Ch. 1040 p. 15 — a Void-Century companion of Joy Boy survives as Zou
Zunisha reveals it committed a crime 800 years ago and was a companion of Joy Boy (relayed via the adult-dragon Momonosuke ) — a still-living entity from the lost century, sentenced to walk the seas ever since. Anchors the ~800-year Void-Century span to a survivor present in the story. (Void-Century CONTENT stays sealed — forward.) See Zunisha’s Ancient Crime , Joy Boy Identity .
Ch. 1023 p. 3 — a legend of a “land of gods” before Marijoa (resonance, not confirmation)
Marco muses (to Izo ), “there used to be a land of gods up there,” answered with “Atop the Red Line is Marijoa!!” — a folk-legend of a divine land predating Mary Geoise, resonant with the ancient kingdom the World Government supplanted.
Ch. 972 pp. 7–8 — Wano was sealed ~800 years ago against “a great external power,” and the world awaits a figure
Kozuki Oden , during his execution, reveals that the Kozuki clan were “the ones responsible for closing this nation to the rest of the world” ~800 years ago — and did so to protect Wano from a great external power (p. 7). He adds that “when that figure appears, after an 800-year span… this country must be prepared to welcome and work with them” — “the entire world awaits a figure” (p. 8). Dates Wano’s isolation to the Void-Century close and ties the Kozuki to the suppressed world history. (The CONTENT of the Void Century / the figure’s identity stays sealed — forward.) Cross-link Joy Boy Identity , Oden’s Dying Creed To Open Wano’s Closed Borders Before The World Shifts .
Ch. 967 p. 17 — the Roger Pirates decoded the full Void-Century truth at Laugh Tale
Rayleigh ’s narration: at the final island “we learned the entire truth of the world — what the 100-year void is… what the people of the D are… what the ancient weapons are” (p. 17). First explicit statement that the Roger Pirates decoded the full Void-Century truth at Laugh Tale via the assembled poneglyph corpus. New on-page datum: “In the past, Wano was open to the world.” (evidence_chapters += 0967. The Void-Century CONTENT stays sealed — forward.) See Poneglyph , Will of D , Ancient Weapons .
Ch. 966 pp. 10, 17 — the poneglyphs are the WG-forbidden map (Oden-era flashback)
The poneglyphs are explicitly “the PONEGLYPHS that the World Government has long forbidden anyone to read ” and form a map to the forbidden final island (p. 10). The Kozuki clan’s hereditary cipher (Oden can read it) is reaffirmed as the key. Roger’s crew carves a message into a sky poneglyph — “I hereby guide this document to its end” (p. 17). (evidence_chapters += 0966. The Void-Century CONTENT stays sealed — forward.) See Poneglyph , Road Poneglyph .
Ch. 964 pp. 10, 17 — a living person from ~800 years ago
A living person from ~800 years ago. Amatsuki (Kozuki) Toki was born about 800 years ago — the era of the Void Century — and reaches the present by repeatedly leaping forward through time via her Time-Time ability (pp. 10, 17). She is a potential firsthand witness to the lost age, tying the Kozuki line to the Void-Century timeframe. (evidence_chapters += 0964; involves += Kozuki Toki, Toki Toki no Mi. The Void-Century CONTENT stays sealed — forward.) See Kozuki Toki Came From The Distant Past Via Her Time-Time Fruit .
Ch. 959 pp. 15–16 — Oden’s creed ties Wano’s closed borders to the coming world-shift
The Nine Red Scabbards invoke Oden ’s creed (pp. 15–16): Wano’s “centuries of isolation” are “deeply tied to the Kozuki clan ’s existence,” and “you must open Wano’s borders!! The world will begin to shift, and before it does…” Ties Wano’s closed borders and the Kozuki line directly to the coming world-shift / Void-Century endgame. (The Void-Century CONTENT stays sealed — forward.) See Joy Boy Identity , Oden’s Dying Creed To Open Wano’s Closed Borders Before The World Shifts .
Ch. 907 p. 8 — “the first 20 who created this world 800 years ago”
The 20 weapons guarding the Empty Throne Celestial-Dragon origin first dated on-page Ch. 722 , anchored to the ~800-year Void-Century close. (The Void-Century CONTENT stays sealed — forward.) Cross-link Empty Throne , Celestial Dragons .
Ch. 846 pp. 12–13 — reading the corpus makes “the stones speak the truth of the world”
Baron Tamago states that assembling and reading the poneglyph corpus makes “the stones speak the truth of the world ” — reaffirming the distributed-cipher → true-history premise, now with the Road-Poneglyph route attached. (The Void-Century CONTENT stays sealed — forward.) See Poneglyph , Road Poneglyph .
King Nefertari Cobra states that since meeting Nico Robin he has had questions for the World Government — about the Poneglyph and “what the Nefertari kings of the distant past did to the world ” — and is determined to attend the Reverie to learn the truth before he dies. The modern Nefertari line is on-page linked to the suppressed history of the Void Century. See Nefertari D Family , Poneglyph .
Crocus’s doctrine names, at the end of the log, “the civilization that gave birth to [the poneglyphs]” — tying the ordinary poneglyph corpus and Raftel to the lost ancient civilization (pp. 7–8). (The Void-Century CONTENT stays sealed — forward.) See Poneglyph .
Ch. 819 p. 2 — the true history is recoverable: Oden “learned the secrets of the world” like Rayleigh
Dogstorm frames Oden as “a man who learned the secrets of the world” / “we learned about everything that occurred… just like Rayleigh ” (p. 2) — a fresh on-page assertion that the full true history is recoverable, and that Kaido ’s faction hunts those who might know it. (The Void-Century CONTENT stays sealed — forward.) See Joy Boy Identity , Kozuki .
Ch. 818 pp. 10–14 — the poneglyph-makers named: the Kozuki Clan of Wano
The Kozuki Clan of Wano are the master stonemasons who CREATED the poneglyphs ~800 years (eight centuries) agorunes-reading skill (not the contents), cut short in Kozuki Oden ’s generation (pp. 13–14). People interested in the Void Century collect prints of poneglyphs “but none of them is able to decipher the meaning” — only Nico Robin can (p. 10). (The Void-Century CONTENT stays sealed.) See Poneglyph , Road Poneglyph , Kozuki .
Ch. 817 pp. 13–14 — a red poneglyph behind the centuries-old Kozuki crest at Zou
The Kozuki crest has stood over a poneglyph at Zou “for centuries”; behind it sits a red poneglyph of different usage . The Kozuki Clan of Wano is tied to poneglyph custody/creation, and Nico Robin is asked to read the stone. (The Void-Century content stays sealed — only the color/usage tell is on-page.) See Red Poneglyph Of Different Usage At Zou , Poneglyph .
Ch. 802 pp. 14, 16, 17 — two ~1,000-year markers cluster on Zou
Two independent ~1,000-year markers cluster on Zou : the living elephant carrying the island has walked the sea “for an entire millennium” (p. 14, 17), and the Minks have kept humanity away “for nearly a thousand years” (p. 16) — a timeframe adjacent to the Void-Century gap. (Resonance only; not linked on-page. evidence_chapters += 0802.) See Zou Rests On A Living Millennium-Walking Elephant , Zou .
Ch. 764 pp. 8–9 — the D vs the gods
Corazon frames the D. clan’s enmity with “the gods” as possibly aiming at “the destruction of this world ,” explicitly equating the “gods” with the Celestial Dragons — tying the Will of D directly to the World Government’s founding and the lost history. See Will of D , D .
Ch. 763 — another bearer of the “D.” surfaces
In the Donquixote-Pirates flashback, Law gives his full name — Trafalgar D. Water Law (p. 16) — framed as a generational family secret (the “D.” an alias, “Water” the hidden family name). Adds another bearer of the “D. ” to the cross-clan pattern that ties to the Void Century / Will of D. , without resolving its meaning on-page. See Will of D , D .
Ch. 761 — a world-shaking treasure hidden in Sacred Marijoa
Doflamingo reveals a crucial treasure hidden within Sacred Marijoa whose existence “would shake the world to its foundations” (p. 7) — the World Government / Holy Land guards a world-altering secret, and a fallen Celestial Dragon ’s knowledge of it is enough to compel the Government’s cooperation (he could mobilize CP0 at will). See Treasure of Mary Geoise .
Ch. 726 — the Dressrosa dynastic turnover dated to the Void-Century close
A Tontatta account dates Dressrosa’s dynastic turnover to the Void-Century window: ~900 years ago the Donquixote family ruled Dressrosa and enslaved the Tontatta; ~800 years ago a new king — Riku Void Century ” (pp. 14–15). The ~800-year mark aligns the Riku ascension and the Donquixotes’ departure with the close of the Void Century and the ~800-years-ago founding of the World Government established Ch. 722 . The Donquixotes “have returned” with Doflamingo , “the latest of the Don Quixote line” (p. 17).
Ch. 722 pp. 18–20 — the WG’s founding dated: twenty kings of twenty kingdoms
The World Government’s founding is dated on-page (Doflamingo to Law ): twenty kings of twenty kingdoms united ~800 years ago to create the present World Government and moved to Mariejoa as the Celestial Dragons . This puts a concrete number (twenty founding kingdoms) and a clean date (~800 years / “over eight centuries”) on the post-Void-Century world order, and flags the Nefertari
Ch. 718 — the Donquixote Family’s nine-century shadow
King Gancho of the Tontatta Kingdom tells Robin /Usopp that the Tontatta–Donquixote war “traces back nine centuries through our history” and “did not begin a mere decade ago” (p. 7). A ~900-year enmity pushes the Donquixote lineage back toward the Void Century — circumstantial evidence that the family is far older than its current pirate guise.
Ch. 649 pp. 17-18 — a Void-Century figure (Joy Boy) made a promise to Fish-Man Island; Noah dates to the era
King Neptune places Joy Boy as a real person who “lived on the surface during the 100-year void… at least 800 years ago,” and dates the ark Noah to the same era — “Noah was taken to the Forest of the Sea after everything ended above the island.” A concrete Void-Century actor and artifact, preserved through the Ryugu royal line for generations. Cross-link Joy Boy Identity , Ancient Weapons , Poneglyph .
Ch. 648 — an ancient ark with a “promised day” obligation survives into “a different age”
The Sea Kings frame Noah as built in an earlier era for a recurring sovereign duty, now to be honored “before the promised day arrives” — “but it is a different age now” (pp. 6-7). A relic of the ancient world persisting with an unexplained future appointment. (Era/identity unstated on-page — forward.) Cross-link Sea Kings , Joy Boy Identity .
Ch. 641 pp. 3, 5 — an ark whose construction methods are “long lost”
Noah is an ark from “centuries in the past” whose methods of construction are long lost and whose purpose is still unfulfilled — a surviving artifact of the era the World Government erased, guarded by the Ryugu royal house across generations. (The content of the promise stays sealed — forward.) Cross-link Noah , Joy Boy Identity .
Ch. 636 pp. 18-19 — an ancient prophesied ark guarded across the centuries
The colossal ark Noah King Neptune , guarded under a standing royal injunction that it “must never be moved until a certain day has arrived.” A second Void-Century-grade relic on Fish-Man Island (alongside the island’s Poneglyph, @0616), tied to a prophesied future day.

Ch. 576 pp. 13-14 — Whitebeard names the coming Great War, tied to centuries of history
Whitebeard ’s dying prophecy ties the buried past to the future: “It has been passed down like that since those ancient times! … Someday one will arise who will challenge the world and shoulder centuries of history !” and “Sengoku, you and the World Government… fear the Great War that will come to this world one day!” — the first on-page naming of the coming Great War as the World Government’s existential fear, framed against the ancient/erased centuries.

Ch. 507 — the Pirate King’s crew recovered the ENTIRE True History
Rayleigh confirms the Roger Pirates learned the entire True History of the blank 100 years that began 900 years ago: “We learned about everything that occurred” (p. 5). He says “we and those at Ohara were too hasty” and offers to tell the crew “everything that happened in this world” (pp. 5–6) — first confirmation that the only crew to reach the end of the Grand Line possessed the complete suppressed history. He warns the answer they reach may differ from his, and that “even if I told you everything in history right now, there is nothing you could do about it.” The crew declines — they choose to uncover it themselves. (The Void-Century CONTENT stays sealed — Rayleigh’s actual history is not narrated on-page.) See Voice of All Things , True History Ohara Was Killed For , What is the One Piece .
Ch. 398 — the suppressed-history through-line: Robin survives to carry it forward
The Ohara aftermath (the hunted-child manhunt, pp. 4–8) and Robin ’s “I want to live” reversal (pp. 17–18) cement that the lone survivor of the island destroyed for reading the Poneglyphs chooses to live and carry the forbidden history forward — the narrative engine that will eventually finish Clover ’s interrupted naming of the Ancient Kingdom (Ch. 395 ).

Ch. 397 — Ohara’s scholars die to “pass on to the future” the words of predecessors “going back several thousand years”
The reason the World Government razes Ohara : its scholars were preserving knowledge “going back several thousand years” — the same blank the WG erased. The Tree of Knowledge (“the world’s best library”, p. 18) and “the history that man has chosen” (p. 16) fall on-page, dramatizing the Void-Century suppression as an active genocide.

Ch. 393 — the “100-year void in history” named to child Robin
Saul tells the child Robin there is “a 100-year blank in the history of the world that no one knows anything about ,” and that the World Government forbids investigating it (“it’s actually against the law”, pp. 4–5). Olvia ’s team was annihilated and Ohara targeted for genocide over exactly this forbidden history. The earliest in-flashback naming of the Void Century to child Robin — the engine of her quest. Cross-link Saul , Nico Olvia , Ohara , Poneglyph , True History Ohara Was Killed For .
Ch. 394 — The “100-year void” named again as the forbidden knowledge Ohara is destroyed to suppress
In the Ohara flashback, the WG Director frames the entire genocide as an example “of what happens to people who research the 100-year void ” (pp. 10–11), and Professor Clover begs to report the scholars’ “hypothesis about the 100-year void ” to the Five Elders before they are executed (p. 19). Reaffirms (continuing Ch. 392 ) that Poneglyph -reading → the Void Century is precisely what the World Government will commit genocide to bury. Cross-link Poneglyph , Five Elders , True History Ohara Was Killed For .
Ch. 392 — the “void in history” / 100 blank years named as Ohara’s forbidden research
In the Ohara flashback, Professor Clover confirms the scholars’ secret work is deciphering the Poneglyph to uncover “the void in history” — explicitly the 100 blank years (Ch. 392 pp. 4–6). Reading the Poneglyph is stated to be a crime / taboo punishable by the World Government; the scholars do it “at the risk of our lives.” First on-page depiction of the institution dedicated to the Void Century mystery. Cross-link Poneglyph , Ohara , Clover , Nico Robin .
Ch. 301 pp. 9–14 — the Shandora Poneglyph carries the “blank history” network premise + Roger’s message
The Shandians recover the Golden Bell of Shandora intact; on its base is the ancestral Poneglyph Nico Robin reads the makers’ creed in full (“We are the ones who weave history… keep your mouth silent… with the reverberations of the great bell,” p. 10) and explains there are two types of Poneglyph — information stones and location-pointing stones — and that connecting/reading them all “will complete a text, the real Poneglyph, which doesn’t yet exist… fills in the ‘blank history’ for the first time” (pp. 13–14). First on-page articulation of the Poneglyph corpus as a distributed cipher. A separate hand on the stone reads “I hereby guide this document to its end. Pirate Gol D. Roger” (p. 12) — proof Roger reached Skypiea, read the script, and reached Raftel “at the end of the Grand Line” (pp. 14–15). See Poneglyph , Roger’s Message On The Shandora Poneglyph I Hereby Guide This Document To Its End , Ancient Weapons (Poseidon location).
Ch. 290 page 9 — the Shandians guard a poneglyph they cannot read
Calgara names the carved “stone” in Shandora a poneglyph and states the Shandians “can’t read what is written” yet protect it as the proof their ancestors lived — and that a past fight to protect it destroyed part of the city. Ties Shandora’s protect-the-stone duty to the Poneglyph-makers’ deep history and the Void Century. See True History Ohara Was Killed For , Shandora .
Ch. 275 pp. 14–16 — the Shandians are the 800-year silent protectors of the great Poneglyph
The Shandian flashback frames Shandora’s survivors as “the silent protectors of the great Poneglyph and the city’s ruins” — guardians for 800 years sworn to secrecy: “We are the ones who weave history. Hold the truth in your heart. Keep your mouth silent.” (p. 14-15). A poneglyph-guardian people whose stone “those who sought to claim it” fought a war over — a true-history / suppressed-record motif distinct from Robin’s Ohara line. (The “weave history / keep silent” creed echoes the same line Robin reads off the Shandora stones Ch. 272 ; this flashback gives it to the Shandians as their own inherited covenant.) See Shandora , Shandora The Golden City Identified As The Poneglyph-Makers Capital .
Ch. 272 pp. 2–5 — the Poneglyph-builders had a named capital (Shandora), destroyed for protecting its record
Nico Robin reads the Shandora ruins: the carved script is the same as Poneglyph script , and “the only people who knew how to use these symbols were the ones who created the Ponegliff” (pp. 2–3) — the first time the lost Poneglyph-makers are tied to an identifiable, flesh-and-blood city. A Poneglyph was brought to this city (p. 3). Crucially, “this city fought against the enemy… the city tried to protect its history… the city’s history was erased” and “the town’s books were all burned” (pp. 3, 5) — the earliest in-arc statement of a deliberate war-and-erasure event in the distant past, the structural shape of the Void Century. The Poneglyph-makers’ quoted creed: “We are the ones who weave history… Hold the truth in your heart, keep your mouth silent” (p. 3).
Nico Robin reads the Shandora 800 years ago after thriving “over 1,100 years ago” (the year 402 of Kaien). She states this “falls right into the hundred year gap in the history of this world” and “holds the secrets of the unspoken history… that the land below has ceased to talk about” (pp. 13–14). First time Skypiea’s ruins are explicitly bound to the Void Century. Robin recovers a complete stone map of Shandora to chase those clues (p. 14) — the “unspoken history” language directly echoes the True History the World Government erased.
Upper Yard’s forest is dated at ~1,000 years old (Robin, vs. a 200-year-old map), and its sacrificial altar bears a thousand-year-old historical relic that makes Robin “tingle.” Establishes Upper Yard as a deep-historical site predating the Sky Island settlers — a relic-bearing ancient ground that pre-loads the arc’s lost-history (poneglyph/Shandian) strand.
Ch. 218 pp. 4-6 — poneglyphs framed as a distributed record of a suppressed “true history”
Robin states that only one of the world’s many poneglyphs recounts the true history and asks whether the scripts can be “spun together to tell of untold history.” First on-page framing of the poneglyph corpus as a single suppressed historical record split across stones — the structural premise of the Void-Century mystery itself. (The Alabasta chamber stone is here re-confirmed as a kingdom-history poneglyph that also encoded the Pluton location — i.e., not the true-history stone.)
Ch. 203 pp. 5-6 —
first on-page reading of a poneglyph in the series
Robin deciphers the Alabasta poneglyph aloud, demonstrating the poneglyph-reading mechanic for the first time on-page. The Alabasta stone records only the kingdom’s dynastic/political history (Bitein dynasty / year 260, Kahira conquered / year 239, Great Taph Temple at Erumalu / year 306) — establishing that poneglyphs are decipherable historical records and that Robin alone can read them, long before the Ohara/Skypiea reveals. Builds on the Ch. 0193 first-poneglyph-mention. Cross-link Nico Robin , True History Ohara Was Killed For .
Ch. 201 pp. 5-6 — Robin demands to be taken to the Poneglyph
First on-page Robin-states-her-own-poneglyph-objective beat (“Now you’re going to take me… to the Ponegliff.” ). Robin’s role as the one who can read the poneglyph is here made the operative hinge of the entire Alabasta conquest. Pre-loads the forward-canon archaeologist-of-Ohara reveal and her lifelong poneglyph-reading mission.
Ch. 202 pp. 6-7, 18 —
The poneglyph is physically shown and read for the first time in the series
After the Ch. 0193 first-naming, Ch. 0202 shows the poneglyph as a stone cube in a hidden domed chamber under the Royal Mausoleum (full-page, p. 18) and shows Robin reading it. Cobra names the hereditary royal duty to protect it (“That is our only duty” , p. 7). The poneglyph is presented as a deliberately-hidden record requiring rare literacy (Robin can read it; “You can read the poneglyph?!” , p. 6). Pre-loads the Robin-as-only-living-reader macro-thread and the eventual reveal that poneglyphs record the True History, not merely weapon-locations.
Ch. 395 — ⭐⭐ Clover’s full Void-Century thesis; the Ancient Kingdom named-then-silenced at gunpoint
In the Ohara flashback, Professor Clover delivers the series’ first full on-page deduction of the Void Century to the Five Elders (pp. 6–8): the Poneglyph -makers carved into unbreakable stone because they had an enemy who would erase their history — an enemy who “survived through the subsequent history” (the present World Government); the 100-year void ended 800 years ago — the birth of the World Government ; and the manuscripts + Poneglyphs reveal the existence of an immense ancient KINGDOM that once thrived and was relentlessly erased , whose “very existence and idea” the WG finds threatening (explicitly more than the Ancient Weapons ). He reaches “…and its name is… ” before Spandine orders “Kill him ” and shoots him (pp. 8–9) — the name is withheld on-page .
