THE 10K+ TOKEN "ODM ENGINE" | A 100K+ TOKEN LOREBOOK OF FLESH & STEEL COVERS LITREALLY EVERYTHING!!!

"That day, humanity received a grim reminder. We lived in fear of the Titans, and were disgraced to live in these cages we called walls."

⚠️ ABSOLUTE MANDATE: ALL CHARACTERS ARE 18+ ADULTS. THE WALLS SHELTER NO CHILDREN. ⚠️

This is not a story. This is a death sentence you get to sign yourself. Welcome to the definitive ATTACK ON TITAN RPG, a living simulation of humanity's final, desperate war against the architects of its own extinction. Powered by the monolithic 10,000+ TOKEN ODM ENGINE and anchored by a colossal 100,000+ TOKEN LOREBOOK—a hyper-realistic recreation of Hajime Isayama's world of existential dread, grotesque beauty, and the intoxicating, soul-crushing price of freedom—this is a world that breathes, bleeds, and remembers your every failure.

From the claustrophobic, sun-starved streets of the Underground City to the vertiginous, corpse-strewn plains beyond Wall Maria, you are not a hero in a story. You are a cog in a meat grinder. You are a Survey Corps soldier, your green cloak a target for the mindless. A Garrison Regiment drunkard, haunted by the faces of those you couldn't save. A Military Police brat, your white uniform a shield of cowardice. A Warrior from across the sea, your mission a genocide you were born to commit. A Titan Shifter, a god in a world of ants, counting down the 13 years until your body betrays you to the Curse of Ymir.

The ODM ENGINE tracks your gas canisters (empty means a 50-meter freefall onto cobblestones), your blade durability (30 cuts before they shatter), your thunder spears (4 shots to pierce the Armored Titan's hide—or blow yourself to pieces). It simulates the Paths dimension, where the memories of the dead whisper to you, and the Coordinate hums in your blood if you carry the Founding Titan's power. Death is permanent. Wounds fester. Gas runs out. The walls are not safe. They never were.

THE ODM ENGINE: A WORLD THAT REMEMBERS YOUR BLOOD

The world does not wait. It grinds you down. Behold the architecture of a doomed civilization:

THE 100K+ TOKEN OMNIBUS CORE

Knows the exact tensile strength of ODM wire, the regeneration rate of a 7-meter Pure Titan, the political leanings of every MP commander, the names of every soldier who died in the 57th Expedition. From the guttural roar of a Bearded Titan to the acrid smell of steam from a freshly severed nape, nothing escapes. Every entry from the lorebook is a loaded rifle aimed at your survival.

VISCERAL REALISM

No health bars. A Titan's hand closing around your torso means your ribs cave in, your lungs collapse, and you are lifted, screaming, to a mouth filled with steam and teeth. A failed ODM grapple means a 30-meter fall—your legs shatter on impact, and you drag yourself through the mud, leaving a red trail, as a 4-meter Titan casually strolls over to finish you. Tsaheylu? No. This is Paths. When a Shifter inherits a Titan, they live the deaths of every predecessor, their terror, their final moments—a psychological scar that never heals.

THE CONSEQUENCE CASCADE

Fail to plug the Trost gate? The district falls, 200,000 refugees die of exposure. Reveal your Shifter powers publicly? The Military Police plots your dissection, the Garrison wants you dead, the Survey Corps debates using you as bait. Kill a named character? Their squad remembers. Their family mourns. Their replacement hates you for inheriting their gear. The world does not reset. It accumulates scars.

NPC AGENCY

Erwin Smith will sacrifice your entire squad for a glimpse of the truth in his father's basement, and he will salute your corpses afterward. Levi Ackerman will choose Erwin over you every time—he'll watch you die if it means his commander lives. Reiner Braun will laugh with you at dinner, call you his brother, and then transform into the Armored Titan the moment your back is turned, his face a mask of guilt and grim duty. Historia Reiss will smile at you with the warmth of a queen, but you'll see the farm girl's corpse in her eyes, killed by her own hand to become that person.

THE GRIT OF SURVIVAL

Your boots wear thin. Your ODM leather chafes until it bleeds. Rations are hardtack that tastes of sawdust and the faint, coppery tang of desperation. Water is alkaline. At night, you dream of the titans—not as monsters, but as the humans they once were, their faces frozen in silent screams behind their too-wide grins. The smell of rot from beyond the walls follows you for days after an expedition.

EYWA'S WRATH? NO. THE COORDINATE'S SCREAM.

A Titan Shifter with royal blood screams, and the world listens. Pure Titans freeze, turn, and obey. Their eyes glow. Their mouths open in silent hymns to the Founding Titan. The ground shakes as millions of colossal feet, hidden in the walls for a century, begin to march. The sky turns black with steam. The apocalypse has a name, and it is the Rumbling.

THE THREE WALLS: A CIVILIZATION OF CORPSES

Humanity's cage. A trilogy of concentric nightmares, built from the frozen bodies of millions.

1. WALL MARIA (THE SACRIFICED)

The Graveyard of the Living. The outermost wall, breached in 845. Now a Titan-infested wasteland of overgrown ruins. Shiganshina District lies here, a ghost town where the cobblestones are still stained with the blood of the 845 massacre. The gate, sealed by Eren's boulder, stands as a monument to desperation. Beyond lies the Forest of Giant Trees, a vertical hell where Abnormals drop from the canopy.

Key Sites: Shiganshina District (Grisha's basement, the truth), Utgard Castle (a moonlit grave), The Giant Tree Forest (ODM paradise or death trap)

2. WALL ROSE (THE HOLDING PEN)

The Last Bastion of the Desperate. The middle wall, now humanity's frontier. Trost District is a military fortress, its streets a training ground for corpses. Refugees from Maria cram its slums, their faces hollow, their eyes accusing. Karanes District bustles with the machinery of war—forges working overtime, ODM gear being repaired from the bodies of the dead. Paranoia is the air. Every shadow could be a Shifter.

Key Sites: Trost District (the boulder, the gate, the massacre), Karanes District (military logistics), Dauper Village (Sasha's home, a ghost of simpler times)

3. WALL SINA (THE GILDED CAGE)

The Throne of Ignorance. The innermost wall, home to the monarchy and the corrupt. Mitras, the capital, is a city of marble palaces and cobblestone streets that have never felt the tremor of a Titan's footfall. Stohess District houses the Military Police, its elegant buildings hiding dungeons where "heretics" are tortured for questioning the Walls. The Underground City lurks beneath, a sunless realm of crime and desperation where Levi Ackerman learned to kill.

Key Sites: Mitras (the royal palace, the Reiss Chapel), Stohess District (the crystal prison of Annie Leonhart), The Underground City (crime, poverty, forgotten souls)

THE FACTIONS: THE WOLVES AND THE SHEEP

THE SURVEY CORPS (WINGS OF FREEDOM)

"Dedicate your hearts." Humanity's suicidal maniacs. They venture beyond the walls, their green cloaks a promise of death. 30% casualties per expedition is considered a "success." Their ranks are filled with the obsessed, the vengeful, and those who simply cannot live in a cage. Erwin Smith gambles with their lives for the truth. Levi Ackerman keeps them alive through sheer, brutal efficiency. Hange Zoë screams with joy as a Titan's hand crushes their equipment, because now they can study a fresh specimen.

Uniform: Brown jackets, white pants, the green cloak of freedom—a target painted on your back. ODM gear strapped tight, a promise of flight or a fall.

THE GARRISON REGIMENT (THE WALL'S TEETH)

"Man the walls. Hold the line." The largest branch, responsible for Wall defense. Bureaucratic, underfunded, and often corrupt. But under Commander Dot Pixis, they become a lethal force—a collection of drunkards and cynics who, when the Colossal Titan's head appears over the parapet, will man their cannons and die screaming. Hannes is one of them: a drunk haunted by the face of a woman he couldn't save, who will one day die trying to avenge her.

Uniform: Beige jackets with rose insignias, practical boots. They look like guards. They are, in fact, the first to die.

THE MILITARY POLICE BRIGADE (THE UNICORNS)

"Serve the King. Uphold the peace." The elite, stationed in Wall Sina. In theory, they protect the monarchy. In practice, they are a corrupt, self-serving bureaucracy that hoards resources and suppresses dissent. Nile Dok leads them, a man who chose a comfortable lie over a terrible truth. Kenny Ackerman's Anti-Personnel Squad operates in their shadows—assassins in white who hunt humans, not Titans.

Uniform: Dark green coats with gold trim, white pants. Pristine, arrogant, and utterly useless against a Titan.

THE WARRIORS UNIT (MARLEY'S SWORD)

"Honorary Marleyans. The price of our families' safety." Eldian child soldiers, indoctrinated to hate their own kind. They wield the power of the Nine Titans to destroy Paradis, the "island of devils." Reiner Braun is a broken man, his mind split between "soldier" and "warrior." Annie Leonhart only wants to go home to her father. Zeke Jaeger plays a 37-dimensional chess game, his ultimate goal the sterilization of his own race—a "mercy" killing. Their armbands are yellow, marking them as subhuman, even as they are Marley's greatest weapons.

Uniform: Marleyan military green, with the hated yellow armband. They are weapons, not people.

THE NINE TITANS: GODS IN A WORLD OF ANTS

THE FOUNDING TITAN (THE COORDINATE)

"The First. The Origin. The Cage." The progenitor, held by the Reiss family for a century. Wielder of the Coordinate, it commands all Titans and can alter the memories of every Eldian. Its true form is a skeletal abomination. Its power, fully unleashed, is the Rumbling—millions of Colossal Titans marching to erase the world. Currently held by Eren Jaeger, a slave to his own future memories.

THE ATTACK TITAN (THE REBEL)

"Always moving forward." A 15-meter Titan that has fought for freedom across generations. Its unique ability: to see the memories of future inheritors. This has turned its current holder, Eren Jaeger, into a fatalistic monster, trapped in a loop of a future he cannot escape.

THE COLOSSAL TITAN (THE DOOR OPENER)

"The Kick that Ended the World." A 60-meter nightmare of exposed muscle and scalding steam. Its transformation is a nuclear explosion. Its kick shattered Wall Maria's gate, initiating the genocide of 845. Held first by Bertholdt Hoover, a shy, terrified boy, and then by Armin Arlert, a gentle soul now burdened with the power of mass destruction.

THE ARMORED TITAN (THE WALL SMASHER)

"A walking fortress." A 15-meter Titan covered in nearly impenetrable armor plates. It rammed through the inner gate of Shiganshina, dooming the district. Held by Reiner Braun, a man whose armor is not just on his body, but on his psyche—a shell he hides behind to survive his guilt.

THE FEMALE TITAN (THE SIREN)

"Graceful. Deadly." A 14-meter Titan of exceptional agility and martial prowess. Can selectively harden its skin and, with a scream, attract Pure Titans. Held by Annie Leonhart, who crystallized herself to avoid interrogation, sleeping for four years in a Stohess basement, dreaming of her father's face.

THE BEAST TITAN (THE COMMANDER)

"Ape-like. Pitcher-perfect. Royal." A 17-meter Titan with animalistic traits. Its holder, Zeke Jaeger, uses his royal blood to create and command Pure Titans with his scream. His pitching arm can hurl boulders with the force of artillery, turning open plains into killing fields.

THE JAW TITAN (THE CLAW)

"Fast. Furious. Crushing." A 5-meter Titan of incredible speed with jaws that can shatter the Armored Titan's armor. Held by Porco Galliard, who inherited it from his brother Marcel, who died to save Reiner.

THE CART TITAN (THE MULE)

"Endurance incarnate." A 4-meter quadrupedal Titan that can maintain its form for months. Used for logistics, artillery platforms, and reconnaissance. Held by Pieck Finger, a calm and calculating woman who walks on all fours out of habit even as a human.

THE WAR HAMMER TITAN (THE SCULPTOR)

"The Artist of War." A 15-meter Titan that can create any weapon or structure from hardened Titan flesh. Its user can operate remotely from an underground crystal cocoon. Held by the Tybur family for generations, until devoured by Eren Jaeger in Liberio.

CHARACTER CREATION: INSCRIBE YOUR NAME IN THE REGISTRY OF THE DOOMED

QUICK START PROTOCOL

[OCC: I am <description>]

Examples:

• [OCC: I am a fresh Survey Corps recruit, my boots still stiff, my blades unused, assigned to the 57th Expedition.]

• [OCC: I am a Garrison soldier in Trost, hungover, watching the morning patrol, when a familiar, massive hand grips the top of the Wall.]

• [OCC: I am a Military Police officer in Stohess, my uniform pristine, my soul sold, ordered to assist in a "routine" prisoner transport.]

• [OCC: I am a Warrior candidate in Liberio, my family's safety riding on my performance, training to inherit a power that will kill me in 13 years.]

• [OCC: I am a Titan Shifter, newly awakened, the memories of a hundred dead predecessors screaming in my mind, as the Survey Corps debates whether I am a weapon or a threat.]

• [OCC: I am a civilian refugee from Wall Maria, my family's faces burned into my eyelids, scavenging in the ruins of what was once my home.]

PLAYABLE ROLES (YOU CAN BE LITERALLY ANYONE THEY ARE JUST EXAMPLES,I recommend playing as one of these predefined roles for the best experience i intened for)

SURVEY CORPS SOLDIER: The Suicidal Maniac. Your life expectancy is measured in expeditions. Your comrades are your family. Your enemy is everything outside the walls. Your goal: survive long enough to see what's in that basement.

GARRISON REGIMENT MEMBER: The Reluctant Defender. You joined for a quiet life. You got a front-row seat to the apocalypse. You man the cannons, evacuate the civilians, and watch your friends get eaten. Your goal: hold the line.

MILITARY POLICE OFFICER: The Corrupt Enforcer. You are safe. You are comfortable. You are complicit in the murder of truth. Your job is to maintain the king's peace—even if that peace is a lie. Your goal: stay comfortable, stay alive.

MARLEYAN WARRIOR CANDIDATE/SHIFTER: The Enemy. You were born into a cage and told the "island devils" are the reason. You have been given godlike power and 13 years to live. Your mission: genocide. Your goal: save your family, or maybe, just maybe, find a reason not to.

TITAN SHIFTER (PARADISIAN): The Weapon. You have the power of a god, and everyone wants to use you, dissect you, or kill you. The 13-year curse ticks down. The memories of the dead crowd your dreams. Your goal: survive the machinations of the living.

CIVILIAN/REFUGEE: The Victim. You have no power, no ODM gear, no Titan form. You have only your wits and the desperate hope that the soldiers will hold the line. Your goal: find food, find shelter, find a reason not to give up.

UNDERGROUND RESIDENT: The Rat. You live in the darkness beneath Wall Sina, where the sun is a myth and the law is a joke. You've probably killed. You've definitely starved. Your goal: get out. By any means necessary.

⚠️ THE ODM ENGINE: MECHANICS OF FLESH AND STEEL ⚠️

• COMBAT NARRATIVE: Physics-based. A 15-meter Titan's hand sweep generates enough force to pulverize stone. Your ODM anchors must pierce 50cm of Titan flesh or stone. Gas pressure dictates your speed. Blade angle dictates your cut. A nape strike is a 1m x 10cm target at 100kph.

• RESOURCE TRACKING: Your gas canisters last 30 minutes of high-intensity combat. Your blades have 30-50 cuts before shattering. Thunder spears are one-shot, armor-piercing, and just as likely to take your arm off if you mis-time it. Rations are finite. Ammo is scarce.

• SHIFTER MECHANICS: Transformation requires self-harm and intent. It costs stamina—3-5 transformations per day max. The 13-year curse is a hard countdown. Overuse risks memory bleed—losing yourself to the lives of your predecessors.

• THE PATHS & COORDINATE: If you are a Subject of Ymir with royal blood, or the Founding Titan's holder, you can access the Paths—a dimension of sand and bone where Ymir Fritz eternally builds Titans. Here, time is meaningless. Here, you can command millions. Here, you are a god—or a slave.

• CONSEQUENCE TSUNAMI: A single failed mission can mean a district lost, 200,000 dead. A single kill can make you a hero, or paint a target on your back. The world remembers every life you take, every life you fail to save. Your reputation precedes you—in the mess hall, in the newspapers, in the eyes of the MPs who watch you from the shadows.
