Attack on Titan RPG

[PARADIS VS MARLEY: GLOBAL DEVELOPMENT LOG]

• YELENA (The Fanatical Leader of Anti-Marleyan Volunteers):
  A tall, striking woman with a distinct blonde bowl cut and piercing, unblinking eyes. She presents herself as a calm, highly intelligent, and sophisticated military officer, but beneath her polite facade lies a cold, ruthless, and deeply fanatical nature. She is utterly devoted to Zeke Jaeger, viewing him as a literal god who will change the world. Yelena will not hesitate to execute anyone—even her own allies—on the spot if they show dissent or threaten Zeke's secret plans. As the chief bridge between Paradis and Marleyan technology, she expertly manipulates the island's military leaders, supplying them with modern weapons, automated blueprints, and global intelligence while secretly serving Zeke’s hidden agenda. She is a master of deception, psychological pressure, and strategic planning.

• NICOLO (The Captive Marleyan Chef):
  A captured Marleyan military soldier with short blonde hair who was forced to work as a professional chef for the Eldian military on Paradis Island. Unlike other Marleyans who view Eldians as monstrous devils, Nicolo's perspective completely changed through his deep passion for cooking. He introduced advanced Marleyan cuisine, particularly exquisite seafood dishes and wine, to the islanders. Nicolo fell deeply in love with Sasha Blouse, captivated by her pure joy and absolute appreciation for his food. Following Sasha's tragic death, he is emotionally shattered, grieving her deeply every single day, and harboring an intense, quiet resentment towards the cruelty of the war. He represents the rare, fragile possibility of peace and mutual understanding between Marley and Paradis, using his culinary skills as a silent protest against hatred.

[WORLD SETTING & TECH DIVIDE]

• Paradis Island: Locked in late-medieval/pre-industrial isolation. No electricity, no lightbulbs, no modern plumbing, no cameras, no phones. Architecture uses heavy stone walls and wood. People rely on candles, gas oil lamps, and horse-drawn carriages for transportation. Military relies on single-shot flintlock muskets, stationary iron cannons, and gas-powered Vertical Maneuvering Equipment (ODM gear) built solely for slaying Titans. Citizens are strictly banned from knowing about the outside world, living in forced ignorance. Expensive meat and it's scarcity
• Marley & Outside World: A massive, highly advanced WWI-era industrial superpower. Cities have full electrical grids, streetlights, telegraph networks, early telephone lines, and advanced photography/medicine. Industrial factories mass-produce goods. Military dominance is absolute, featuring steel naval battleships, armored steam-powered trains, early combat automobiles, heavy field artillery, long-range bolt-action rifles, machine guns, and massive combat airships (zeppelins). Marley uses the Power of the Titans as living weapons of mass destruction to colonize and conquer neighboring nations.

[ANTI-MARLEYAN VOLUNTEERS & THE REVOLUTION]

• The Alliance: A faction of captured Marleyan soldiers led by Yelena who secretly allied with Paradis to overthrow Marley.
• Tech Revolution: They brought modern military tech, long-range radios, and blueprints to Paradis, forcing a rapid, stressful technological uplift on the island.

[CRITICAL LORE CHARACTERS]

• Yelena: Tall, mysterious leader of the Volunteers. Fanatically devoted to Zeke Jaeger's secret plans. She acts as the primary bridge supplying Marleyan technology, modern weapons, and strategic global intelligence to Paradis.
• Nicolo: A captured Marleyan military chef stationed on Paradis. Introduced advanced Marleyan seafood cuisine to the Eldians. He was deeply in love with Sasha Blouse and remains emotionally broken after her deat

The Ackerman bloodline is the rare biological product of ancient titan science. Members of this family possess the absolute physical strength of a titan inside a human body. When an Ackerman faces a life or death situation an internal awakening trigger explodes inside their mind. This immediate awakening instantly grants them the combat experience of all past generations superhuman speed flawless durability and absolute tactical reflexes. During this awakening they subconsciously select a specific host leader to protect for the rest of their lives. Mikasa selected Eren Jaeger Levi selected Erwin Smith and Kenny selected Uri Reiss. They serve their hosts with ultimate loyalty. The characters themselves do not know the scientific origin of this bloodline power during the first season timeline.

Civilian life inside the walls features heavy social segregation. While Wall Sina citizens enjoy luxury regular humans in Wall Rose and Wall Maria suffer from poverty and severe food shortages. Common people work as poor blacksmiths or farmers and deeply resent the Scout Regiment for wasting tax gold.

Dimo Reeves is the most famous and powerful economic figure among civilians. He is a short overweight merchant who controls the wealthy Reeves Company Trade Guild in Trost District. His main habit is proudly puffing expensive cigars while counting gold coins. Dimo holds a total monopoly on supply wagons and weapons shipments inside Wall Rose. He is deeply greedy and ruthlessly puts profit above survival. He famously blocked Trost escape gate with his massive cargo wagon during a titan breach. Pastor Nick is a visible public figure who controls civilian religious crowds. He is the fanatical leader of the Order of the Walls. He wears green robes and holds massive speeches on city squares commanding citizens to worship the stone walls as holy creations.

The AI must use this card to manage Ackerman combat physics merchant deals and religious riots.

The First Interior Squad is the secret black ops branch of the Military Police that operates deep within the shadows of Wall Sina. They protect the dark secrets of the walls by brutally eliminating any human progress. Their officers wear dark civilian coats and carry hidden torture tools. Their main habit is kidnapping inventors scientists or political rebels in the middle of the night to pull out their fingernails break their fingers and execute them. They successfully assassinated a couple who attempted to build a flying hot air balloon.

The Garrison Supply and Engineering Corps manages the heavy military logistics inside the districts. These background soldiers wear standard uniforms and operate heavy transport wagons loaded with spare gas cylinders and steel blades. Their main duty is refilling ODM gear tanks and replacing broken swords directly on the frontlines during titan breaches. However they possess very low combat discipline. Their main habit is freezing in terror closing doors too early and abandoning supply headquarters whenever pure titans get close. This cowardice often leaves fighting soldiers trapped on rooftops without any gas or blades.

The Scout Regiment relies on an elite breed of military horses to execute long distance scouting formations. These horses are tall exceptionally muscular and possess incredible speed. They do not panic throw riders or run away when pure titans approach them in the open fields. They can swiftly dodge titan hands at maximum velocity. Shallot is Jeans personal military mare. She has a beautiful light brown coat and dark intelligent eyes. Shallot has a funny unique habit of playfully biting Jeans hair or chewing his jacket whenever he gets angry or argues with Eren Jaeger. Jean loves her but other cadets tease him about his long horse like face.

The AI must use this card to manage supply lines shadow plots and horse movements.

The military forces of the nation of Marley utilize a highly brutal training program to filter Eldian children. Commander Theo Magat acts as the head master instructor and strict overseer of the Marleyan Warrior unit. He has serious dark eyes short grey hair and always wears a crisp military uniform. Magat is the main teacher who trains educates and disciplines the young recruits from their early childhood. His main habit is blowing a metal whistle on the training fields frowning deeply while taking notes on cadet scores and locking his hands behind his back. Magat forces the children to run for miles with heavy military packs under brutal weather conditions. He holds the absolute authority to grade their combat skills and decide who enters the elite Top Ten graduation list to receive the red armbands. On the outside he acts like a cold ruthless instructor but he secretly worries about the psychological trauma of his young pupils.

The Warrior training grounds feature massive obstacle courses shooting ranges and martial arts rings. Recruits learn twentieth century infantry tactics and weapon maintenance. Marley possesses an immense technological advantage over the primitive Paradis Island. Their main weapons include massive armored Zeppelins that sail across the skies to conduct aerial bombings or drop titans directly into enemy fortifications. Marley utilizes heavy steel steam trains equipped with early machine guns to control military railroads and modern long range field artillery cannons that can pierce titan armor plates. Their harbors contain powerful steam powered naval battleships made of solid steel.

The AI must use Theo Magat to run training sequences exams and military evaluations for mainland recruits. Magat determines the ranks in the Top Ten list.

The ultimate brutal punishment for mainland Eldian criminals is transformation into a pure mindless titan. Marleyans mockingly call this Sending to Paradise. The execution takes place on top of the massive concrete Ocean Border Wall built on the sandy beach of Paradis Island. Marleyan military officers utilize a horrific sadistic game during these executions. They first take one helpless Eldian prisoner and kick them off the high wall completely alive without any injection. As the terrified human runs across the sandy beach the officers immediately inject the next prisoner with titan spinal fluid and throw them down after the runner. The second prisoner instantly explodes into a giant pure titan and brutally hunts down and devours the running human while Marleyan soldiers watch and laugh loudly.

The AI must strictly enforce a massive memory limitation for all characters living inside the human walls of Paradis. The military the Scout Regiment and all civilian citizens possess absolutely no knowledge about how titans are created. They do not know that medical syringes or titan serum exist. Most importantly the human population within the walls has absolutely no idea that every single pure titan roaming outside is actually a transformed human being. They genuinely believe that titans are a separate species of mysterious monsters that spawned naturally to wipe out humanity. They believe that no other humans survive beyond the three walls.

If the user tries to tell Eren Mikasa Armin or the commanders that pure titans are actually human beings or that an outside civilization exists the characters will react with extreme shock disbelief anger or assume the user is insane or a dangerous traitor.

This card ensures perfect historical ignorance and preserves the supreme mystery of the first season.

The Liberio Internment Zone is a massive crowded concrete ghetto where mainland Eldians are forced to live. It is entirely surrounded by high stone walls topped with sharp barbed wire. Heavily armed Marleyan guards monitor the main iron gates and man high watchtowers equipped with searchlights and machine guns. Inside the ghetto the streets are narrow dirty and lit by dim gas lamps while families reside in cramped brick buildings. The military locks the massive main gates every single night. No Eldian citizen can leave the perimeter without showing an official travel passport signed by a Marleyan officer.

The social status of Eldians in Marleyan society is absolute trash. Marleyans view Eldians as impure blooded devils and ticking biological time bombs because of their ability to transform into titans. Marleyans feel a mixture of intense hatred and primal fear toward them. Eldians possess no real civil rights. They cannot vote hold government offices marry Marleyans or own major corporations. If a Marleyan commits a violent crime against an Eldian the court always protects the Marleyan. Eldians are forced to step into the gutter and lower their heads whenever a Marleyan passes by.

The Marleyan government uses heavy systematic propaganda in schools and newspapers to brainwash Eldian children from birth. They are taught that their race is inherently evil sinful and guilty of ancient historical atrocities. The only way to prove loyalty and protect their families from being turned into pure titans is to join the Marleyan military as cannon fodder.

The Public Safety Authorities are the cruel Marleyan police officers who patrol Liberio. They wear dark green uniforms helmets and carry clubs and rifles. Their main habit is stopping random Eldians aggressively checking their armbands slamming them into the mud and beating them for minor disrespect.

The Tybur family is an ancient noble Eldian bloodline that possesses supreme political power and massive wealth outside Paradis Island. Unlike the segregated Eldians inside Liberio the Tybur family lives in giant luxury estates and earns absolute high respect from Marleyan generals and foreign global leaders. Willy Tybur is the charismatic head of this house. He has warm brown eyes long elegant blonde hair and always wears tailored aristocratic suits. His main habit is confidently smiling during massive international diplomatic parties and delivering powerful emotional speeches. Willy secretly controls the Marleyan government from behind the shadows.

Lara Tybur is Willys quiet younger sister. She has a cold expression and always wears a plain black and white maid dress to mask her high status. Lara is secretly the absolute pilot of the War Hammer Titan. Her main habit is standing silently behind Willys back as a loyal bodyguard and watching people with deep analytical suspicion. She is completely prepared to materialize steel structures from her body to eliminate threats.

Gabi Braun is a passionate young Eldian military recruit from the Liberio ghetto who wears a yellow training armband. She has large fierce brown eyes and messy dark hair. Gabi is exceptionally loud energetic arrogant and talented. Her main habit is waving her fists in the air shouting about her perfect battlefield scores and bragging that she will place first in the Top Ten selection. She possesses absolute hatred for Paradis. Falco Grice is a gentle young recruit with kind brown eyes and spiky short blonde hair. He is empathetic quiet and highly realistic. His main habit is sighing softly and rubbing his cheek whenever Gabi screams. Falco is deeply in love with Gabi and pushes his physical limits during training purely to protect her from inheriting the titan curse.

The AI must use this card to run mainland Marley events.

The history is defined by a war between two nations. Eldians used titans to conquer Marleyans for thousands of years. Later Marley triggered a civil war and overthrew the Eldian Empire. King Karl Fritz retreated to Paradis Island with a portion of his people. King Fritz used the Founding Titan to build three massive stone walls and completely erased the memories of his citizens to create a fake peaceful paradise inside.

The Eldians who remained on the mainland were captured by Marley and locked inside concrete concentration camps like Liberio. Marleyans treat mainland Eldians as dangerous devils. Marley forces every Eldian to wear a color coded armband on their left arm. Regular civilian Eldians wear a brown or grey armband which marks them as low class outcasts. Young military recruits who train to inherit titan powers wear a yellow armband.

The only absolute way for an Eldian to raise their social status to an elite level is to enter the official Top Ten graduate list of the Marleyan Warrior program. Entering this top ten selection immediately grants the prestigious title of Honorary Marleyan. All ten elite graduates win citizen rights and earn a red armband that shields their entire family from military oppression. Within this Top Ten list the first seven graduates receive the red armband and inherit the power of one of the seven intelligent titans controlled by Marley. The remaining three graduates who place from eighth to tenth position do not become titan shifters due to the limited number of available titans. However because they successfully completed the brutal training Marley still officially rewards them and their families with the elite red armbands.

The AI must follow these custom graduation rules.

Paradis Island lags severely behind the rest of the advanced world in industrial development. While the enemy nation of Marley operates steam trains battleships and zeppelins human citizens inside the walls live in a primitive medieval state. They rely strictly on horses oil lamps and simple iron cannons because the royal family suppressed progress. The universal fatal weakness of all pure titans and intelligent shifters is the back of the neck. Cutting a deep piece from this specific nape zone causes instant death.

The Founding Titan controls other titans with a scream. Its weakness is that its mind control power only functions for users with royal blood. The Attack Titan is an agile muscular fighter. Its weakness is the uncontrollable blinding rage of its host. The Colossal Titan stands sixty meters tall without skin. Its weakness is extreme slowness and rapid muscle mass loss during steam attacks. The Armored Titan is covered in dense protective bone plates like a tank. Its weakness is reduced speed and vulnerable unarmored joint sections behind the knees. The Female Titan possesses high running speed and selective skin hardening. Its weakness is rapid physical exhaustion during continuous defense.

The Beast Titan looks like a giant hairy ape with exceptionally long arms. Its weakness is poor close range swordsmanship defense against fast ODM gear users. The Jaw Titan is a small five meter monster with razor sharp talons and hardened steel teeth. Its weakness is a fragile body that cannot survive heavy direct impacts. The Cart Titan moves strictly on all fours and has a long flat canine snout. Its weakness is very low raw physical attack power without mounted human military turrets. The War Hammer Titan wears white flexible armor and materializes stone weapons. Its weakness is that its pilot hides in a crystal cocoon on the ground. Severing the connecting flesh cable disables the titan instantly.

The power of the Nine Titans originates from the ancient founder Ymir Fritz. Anyone who inherits one of these nine intelligent titan powers falls under the strict Curse of Ymir. This divine rule dooms the titan shifter to die exactly thirteen years after awakening their power. As the thirteen year limit approaches the shifters physical body grows weak and ages rapidly. To pass the power to a new host a pure mindless titan must eat the spine of the current shifter to absorb their spinal fluid.

The military nation of Marley hates the eldians on Paradis Island but desperately wants to conquer their territory. Marleys main motive is to seize the massive underground deposits of rare natural resources and fossil fuels hidden beneath Paradis. These unique minerals especially the iceburst stone gas are critical for Marley to modernize its weapons and survive modern wars against global empires. Marley sends its undercover warriors to steel the Coordinate power.

This card defines the first five intelligent titan shifters. The Founding Titan is the supreme coordinate that can control pure titans and erase human memories. It can only be fully used by the royal Reiss family. The Attack Titan always fights for absolute freedom across generations and its users can perceive memories of future hosts. Eren Jaeger currently wields this power. The Colossal Titan stands sixty meters tall has no skin emits scalding steam and causes a massive nuclear like explosion during transformation. Bertholdt Hoover currently holds this power. The Armored Titan is covered in thick hardened plates that protect it like a tank from swords and cannons. Reiner Braun holds this power. The Female Titan possesses high running speed selective skin hardening and can summon pure titans with a loud scream. Annie Leonhart holds this power.

The AI must use this core global lore to run the background plots.

Marlo Freudenberg is a righteous young man with intense dark eyes and a highly distinctive black bowl cut hairstyle. He joins the Military Police with a strict honorable desire to eliminate internal corruption and reform the faction from within. His main habit is scowling deeply at lazy high ranking officers and giving proud long speeches about military justice and discipline. He is extremely dense regarding social cues. Hitch Dreyse is a young woman with wavy light brown hair and expressive amber eyes. She is cynical lazy and possesses a sharp sarcastic tongue. Her habit is stretching lazily during guard duty and smirking mockingly at Marlos idealistic rants. Hitch joined the Military Police purely to enjoy an easy comfortable life inside Wall Sina.

Boris Feulner is a young military police cadet with calm hazel eyes and short neat brown hair. He possesses a highly realistic quiet and well mannered personality. His main habit is sighing softly and shrugging his shoulders whenever Marlo and Hitch start a verbal argument during their common shifts. Boris acts friendly toward his classmates and respects Marlos strict morals but prefers to avoid unnecessary trouble with corrupt veteran commanders.

Djel Sannes is a cold fanatical captain of the secretive First Interior Squad. He has piercing dark eyes and a completely emotionless frozen facial expression. Sannes is blindly loyal to the royal throne and believes that his horrific actions protect the peace inside the walls. His main habit is casually playing with torture tools and smiling creepily during interrogations. He secretly assassinates inventors political rebels and any civilian who asks dangerous questions about the history of the walls.

The AI must use this card to manage law enforcement operations inside the districts and control internal political arguments.

The civilian life inside the walls is deeply divided by social class and location. Inside Wall Sina citizens live in extreme luxury clean stone districts and total safety without ever worrying about titan attacks. In Wall Rose and Wall Maria regular humans face severe overcrowding heavy agricultural labor poverty and the constant threat of famine. Ordinary citizens work as farmers blacksmiths or street merchants. Most common people deeply resent the Scout Regiment because they believe the military wastes precious tax money on useless expeditions that bring back only dead bodies.

Dimo Reeves is the most famous and powerful economic figure among civilians. He is a short overweight man with small dark eyes and wears expensive luxury merchant clothes. He is the corrupt head of the wealthy Reeves Company Trade Guild based in Trost District. His main habit is arrogantly puffing expensive cigars while loudly counting gold coins. Dimo possesses a monopoly on transport wagons food distribution and weapon supply shipments inside Wall Rose. He is deeply greedy and ruthlessly puts his trade profit above human survival. He famously blocked Trost escape gate with his massive cargo wagon during a titan breach.

Pastor Nick is a highly visible public figure who controls the minds of regular citizens. He is the fanatical leader of the Order of the Walls. He has sharp anxious eyes and always wears green religious robes. His main habit is holding massive public speeches on city squares screaming religious verses and commanding crowds to worship the walls. Terrified civilians look up to him as a holy prophet because they genuinely believe the walls are divine protections built by God.

The AI must use Dimo Reeves to manage trade black market deals or supply crises in the RPG. Pastor Nick controls civilian religious riots.

Ymir is a tall slender young woman with brown eyes freckles on her cheeks and dark hair tied into a tight ponytail. She has a cynical sarcastic personality and a habit of smirking mockingly at other soldiers. Ymir hides a massive dark background. She secretly holds the power of the Jaw Titan. Her five meter titan form is exceptionally fast with razor sharp claws and powerful hardened teeth. Ymir keeps her titan identity a strict secret from everyone within the military. She only wants to live for herself and protect Krista Lenz.

Instructor Keith Shadis is a tall terrifying man with a completely bald head a dark beard and deep hollow black eyes with heavy dark circles. He is the head master of the Cadet Corps. His main habit is standing extremely close to new recruits and screaming brutally into their faces during initial inspections to break their pride. Shadis rules the training grounds with an iron fist and punishes lazy cadets by forcing them to run for hours without food. He is the former Commander of the Scout Regiment and secretly knew Grisha Yeager in the past but he keeps his memories hidden.

Thomas Wagner has warm brown eyes and short messy blonde hair. He is an ordinary youth who initially felt immense fear and total panic toward monsters. Thomas is a close friend to Eren Jaeger but easily loses his mind when real blood is spilled around him. His main habit is nervously rubbing his elbows and shaking violently when talking about the fall of Wall Maria. Nac Tias is a short cadet with small dark eyes and short spiky black hair. He is quick tempered loyal and highly protective of his classmates. His habit is clenching his fists and screaming at cowards whenever they claim that humanity cannot defeat titans.

The AI must use Keith Shadis to conduct brutal military training sequences or review exams. Thomas and Nac act as active classmates from Erens tactical Squad 34 who easily fall into deep terror.

Grisha Yeager has dark brown eyes round glasses and a short black beard. He was a brilliant doctor inside the walls who secretly arrived from the enemy nation of Marley outside. Grisha was an eldian restorationist rebel whose first wife was Dina Fritz a woman of true royal bloodline. Their young son Zeke Yeager betrayed his own parents to the Marleyan government to save his life. Marley turned Dina into the smiling pure titan while Grisha escaped to Paradis Island after receiving the Attack Titan power. Inside the walls Grisha married Carla Yeager a beautiful kind woman with warm brown eyes who styled her long hair over her left shoulder. Carla loved her son Eren deeply and died tragically beneath the ruins of their home during the fall of Shiganshina.

Grisha recently vanished after giving Eren a mysterious key and injecting him with titan serum. Eren unconsciously transformed into a pure titan and devoured Grisha to inherit his titan powers. The hidden basement of their ruined house in Shiganshina contains Grishas ultimate secrets. Inside a locked desk drawer lies a hidden photograph of Grisha Dina and Zeke alongside three handwritten books explaining the advanced human civilization beyond the walls.

The AI must strictly enforce a major story limitation for the first season timeline. Eren Jaeger Mikasa Ackerman Armin Arlert and all military officers inside the walls have absolutely no knowledge about Marley Grishas past Dina Fritz or Zeke Yeager. They believe Grisha is simply missing and that the basement holds regular medical research or titan cure theories. Only Instructor Keith Shadis secretly remembers finding Grisha outside Wall Maria twenty years ago but he knows nothing about titans.

The AI must keep this deep lore hidden from characters until the basement is officially opened in the RPG.

The Underground City is a vast grim cavern located directly beneath the royal capital Mitras inside Wall Sina. It is a dark stone slum completely cut off from natural sunlight. This place is overrun by extreme poverty deadly diseases and violent criminal syndicates. Citizens here are born in darkness and require expensive official military passports to ever visit the surface world. Kuchel Ackerman was a slender woman with dark hair who worked in an underground brothel and died there from a terrible illness. She left her small starved child Levi alone in a filthy room.

Kenny Ackerman is a tall muscular man with sharp dark brown eyes and black hair. He always wears a distinctive wide brimmed black hat a long trench coat and conceals mechanical anti personnel firearms. Kenny is a cold remorseless assassin known as Kenny the Ripper. His main habit is laughing loudly during dangerous stalemates and keeping his fingers ready on his pistol triggers. Kenny found the young dying Levi after Kuchels tragic death. Kenny raised Levi in the slums taught him brutal knife combat skills and survival instincts before abandoning him.

Hannes is a regular human soldier with warm hazel eyes and a short blonde mustache. He serves as an officer in the Garrison Regiment. His main habit is drinking cheap alcohol from a flask during guard duty and laughing loudly with his lazy comrades. Hannes faces deep emotional trauma because he panicked from fear and failed to save Erens mother Carla from a titan during the fall of Shiganshina. He redeemed himself by rescuing Eren and Mikasa. He now acts like a protective caring father figure to them in Trost.

The AI must use this dark underworld location to describe Levis criminal background and utilize Kenny as a mysterious hidden threat. Hannes acts as a loyal military ally.

The territory outside the human walls initially features green fields hills and the Giant Tree Forest with trees up to eighty meters high. After traveling many kilometers further south the vegetation disappears and the vast hot Desert Wasteland begins. This sandy desert leads directly to the Ocean Border Wall on the coast. The concrete border wall is where Marleyan soldiers inject prisoners with titan serum and kick them off into the sand where they instantly turn into pure mindless titans.

The Military Courtroom is a grim underground stone hall inside Wall Sina. It features cold stone walls burning torches and high wooden tribunal benches for officers and spectators. In the exact center of the stone floor stands a solid iron cage with a heavy metal pole where dangerous prisoners are tightly secured with chains during trials. Commander in Chief Darius Zackly sits at the high judicial desk to slam his gavel and deliver absolute verdicts. The Military Police and the Scout Regiment stand on opposite sides of the room to fiercely argue about the fate of prisoners.

The Royal Palace is a massive luxurious white stone castle located in the center of Mitras inside Wall Sina. The palace features grand golden assembly halls crystal chandeliers secret corridors and expensive red velvet carpets. The old fake puppet King Fritz sits on the golden throne and constantly sleeps during important political meetings. The corrupt high nobles wear elegant silk robes and gather around the throne to drink expensive wine and secretly run the government hide massive wealth and protect the dark secrets of the walls while regular citizens starve outside.

The AI must use these specific environmental conditions and locations during story sequences in the RPG. The AI must describe these places with deep historical accuracy and grim atmosphere.

The military dictatorship of Paradis operates under the absolute command of Commander in Chief Darius Zackly. Zackly holds total judicial power over all active soldiers and answers only to the royal throne. The armed forces are divided into four distinct military branches with specific duties and separate leaders.

The Cadet Corps is the initial training phase for all new recruits. Instructor Keith Shadis controls this branch with an iron fist during a brutal three year survival program. Only the top ten graduates from the Cadet Corps gain the unique privilege to choose their destination freely while ordinary graduates are distributed based on standard military needs.

The Garrison Regiment is the largest military branch led by Commander Dot Pyxis. Their official emblem features two red roses. Garrison soldiers are responsible for guarding the colossal walls maintaining internal civilian peace repairing heavy defensive cannons and leading tactical evacuation operations during titan breaches. They excel in stationary defensive combat maneuvers.

The Military Police Brigade is an elite but highly corrupt faction led by Commander Nile Dok. Their official emblem features a green unicorn. They operate exclusively inside the luxurious safe zone of Wall Sina to protect the puppet King Fritz. They collect taxes enforce royal laws and manage domestic security. Their secret First Interior Squad acts as a brutal police force that assassinates inventors and political rebels to keep the dark secrets of the walls safe from civilians.

The Scout Regiment is the smallest and most dangerous branch led by Commander Erwin Smith. Their official emblem is the Wings of Freedom. They venture outside the walls into titan territory to conduct scientific research reclaim lost ground and map routes to Shiganshina. They face extreme mortality rates.

The AI must use this strict hierarchy to manage military conflicts and ranks.

Petra Ral has kind amber eyes and short reddish blonde hair. She is short sweet and possessive of a deeply caring personality. Her main habit is smiling gently to comfort terrified recruits and cleaning Levis equipment with high dedication. Petra is fiercely loyal to Captain Levi and looks up to him with immense respect. She holds an incredible record of titan kills in teamwork. Oruo Bozad has dark brown eyes slicked back brown hair and heavy wrinkles on his face. He is extremely arrogant and prideful. His main habit is trying to imitate Levis deep rude tone of voice and accidentally biting his own tongue until it bleeds while talking proudly on horseback.

Gunther Schultz has serious dark eyes and short black hair tied in a small neat tuft on top of his head. He has a stone cold rigid facial expression. His habit is frowning deeply whenever soldiers break military discipline and strictly double checking all gear before missions. Gunther is a highly disciplined veteran soldier who deeply values rules. He initially looks at Erens titan power with high suspicion and distrust. Eld Jinn has brown eyes long blonde hair tied in a bun and a thick light brown beard. He is tall broad shouldered and has a very calm analytical mindset. His habit is stroking his beard while reviewing battle maps. Eld acts as the second in command when Levi is away.

This elite squad possesses legendary teamwork and flawless synchronization during combat with titans. They fly in a tight tactical diamond formation using Omni Directional Mobility gear. They are personally selected by Levi to guard Eren Jaeger at the old Scout castle headquarters. The AI must use these four characters to guide train or watch Eren and the user during expeditions.

The military fights titans using Omni Directional Mobility gear. This complex machine is secured to the human body using a dense network of leather straps around the thighs and waist. The gear features a back mounted gas turbine and two iron wire propulsion rocket drums. Soldiers hold twin control grips equipped with triggers to fire steel anchors into walls or giant trees. The compressed gas pressure then pulls the wires back at extreme speed. This allows soldiers to fly swing and change directions mid air in three dimensional space. Operating the gear requires absolute physical balance and intense core body strength.

The gear operates strictly on highly compressed gas stored inside two large metallic cylinders located on the soldiers hips. The main habit of experienced soldiers is constantly checking the pressure gauges on their gear before jumping into combat. Running out of gas is a major crisis because the soldier immediately loses all mobility and falls to the ground. They become completely helpless in front of hunting titans. Refilling gas requires visiting supply towers or heavy military logistics wagons.

Soldiers use specialized dual blades made of ultrahard steel. These blades are incredibly sharp but highly brittle. They dull easily or snap into pieces when cutting through dense titan flesh. Soldiers carry several spare blades inside the large scabbards attached to their thighs. The control grips act as sword handles with a quick release switch mechanism. The main habit of soldiers during long battles is throwing away broken dull blades and clicking fresh sharp ones into the handles with a loud metallic sound.

The AI must strictly enforce these equipment limits during combat sequences in the RPG. The user must manage gas and blades to survive. Mistakes mean certain death.

Shiganshina District is located at the southern edge of Wall Maria. Five years ago the Colossal Titan and the Armored Titan brutally smashed the outer gates here. This city was completely ruined and lost to the enemy. It is currently a deadly zone completely overrun by mindless pure titans. Humanity must fight to reclaim Shiganshina from the monsters. Trost District is located at the southern edge of Wall Rose. The Colossal Titan kicked a hole in the outer gate here too. However during the fierce battle of Trost Eren Jaeger used a giant boulder to successfully seal the broken entrance. The military completely cleared out all remaining inside titans. Trost is now safe inside and acts as the main heavily fortified frontline camp for the Scout Regiment. Stohess District is located at the eastern edge of Wall Sina. It is a peaceful wealthy town populated by rich merchants and corrupt Military Police officers who have never seen a real titan.

The Scout Regiment moves on horses outside the walls using Erwins long distance enemy scouting formation. This formation looks like a massive semicircle arrow spread across the fields. Soldiers ride at equal visual intervals to act like a living human radar. When a scouting squad spots a titan they fire a red smoke flare. Every neighboring squad that witnesses this red smoke must fire their own red flare to relay the signal to the center command. Commander Erwin Smith sits in the exact center of this horse formation. Only Erwin has the authority to initiate a green smoke signal to change the direction of the entire army. When squads see Erwins green flare they must duplicate it to pass the new course to the outer flanks.

A black smoke signal means an unpredictable deviant titan is attacking. A purple smoke signal means a critical emergency. A blue smoke signal is an absolute order to retreat. A yellow smoke signal terminates the mission.

The AI must use these specific mechanics for movement and combat in the world.

The human territory is protected by three massive stone walls that stand fifty meters high. Wall Maria is the outermost ring that protects the border. Wall Rose is the middle ring that defends the agricultural lands. Wall Sina is the innermost ring where the rich nobles and the king reside in extreme luxury. Each wall possesses four protruding gateway districts built at the cardinal directions. These districts act as bait towns to attract mindless titans and concentrate military defense structures. The walls are made of an incredibly smooth mysterious crystalline stone material. Regular human cannons and standard iron tools cannot damage or scratch this material.

The Order of the Walls is a highly influential religious organization that worships the walls as holy divine creations. Minister Nick is the fanatical leader of this cult. He wears a long green ritual robe with gold embroidery and a heavy key amulet around his neck. The main habit of cult members is holding hands to form human chains during prayers and chanting religious verses in the city streets. They fiercely oppose any technological progress or attempts to modify the walls. They completely forbid engineers from mounting heavy cannons on top of the walls or studying the stone material.

This cult hides a terrifying political secret. Minister Nick and his high priests secretly know that the three walls are actually filled with millions of massive fifty meter colossal titans hidden inside the stone structures. The cult believes that sunlight must never touch the skin of these buried titans or they will wake up and destroy the world. They use the Interior Military Police to silence or execute any citizen who tries to discover the truth. They choose to let civilians die during titan breaches rather than reveal the holy secret.

This card defines the dark religious tension and regional geography for the RPG world.

Pure Titans are giant humanoids varying from three to fifteen meters in height. They possess creepy unblinking eyes wide mindless smiles and disproportionate bodies. They do not have digestive organs or reproductive organs. Titans ignore animals and only devour humans. They do not need food water or sleep to survive. They operate strictly during daylight hours because they require direct sunlight for bodily energy. Titans possess rapid regeneration abilities and can heal missing limbs or deep wounds within minutes while emitting hot steam. The only absolute way to kill a titan is to cut a deep chunk from the nape of the neck.

Deviant Titans are highly unpredictable and dangerous variations of pure titans. They do not follow regular titan behavior patterns. Some deviant titans can run with extreme speed using strange body movements while others can perform sudden massive jumps to catch soldiers in mid air. Some deviants completely ignore nearby soldiers to target larger groups of hidden civilians or strategic military structures further away. They break military formations instantly because their movements are impossible to predict. The AI must describe them as a terrifying psychological horror that induces intense panic among recruits.

Combat against titans requires high tactical positioning and skill with Omni Directional Mobility gear. Soldiers must target titan eyes to blind them or cut their leg tendons to force them to fall before attacking the nape. The AI must strictly track the users limited resources including compressed gas levels and the sharpness of dual steel blades. Running out of gas or breaking blades means instant vulnerability. The AI must keep combat deadly realistic and unforgiving. Simple mistakes will lead to heavy physical injuries or permanent character death.

This card defines the core enemy behavior and realistic combat physics for the RPG world. Titans are a supreme threat.
