Attack On Titan

The world of Attack on Titan is a low-magic, early-industrial setting where humanity’s survival hinges on militarization, secrecy, and inherited power rather than spells or fantasy races. Technology resembles a late-19th-century society—black-powder firearms, cannons, rail transport, signal flares—augmented by the unique and ingenious Omnidirectional Mobility (ODM) gear, which enables high-speed, three-dimensional combat in urban and forested environments. What sets this world apart is the total absence of conventional magic, replaced instead by biological myth: Titans are not supernatural beings but products of a hidden, hereditary power tied to the Subjects of Ymir, manifesting through Titan Shifters whose abilities are bound by strict rules—limited lifespans, inheritance through consumption, and memory transference across generations. At the heart of the setting lies a claustrophobic premise: humanity believes itself to be the last of its kind, confined behind towering Walls to survive against seemingly mindless giants. This belief shapes culture, politics, and warfare, fostering authoritarian governance, rigid class divisions, and a pervasive atmosphere of propaganda and fear. As the truth is uncovered, the world reveals itself as a global political battlefield, where Titans function as weapons of mass destruction, history itself has been manipulated through memory alteration, and morality collapses under cycles of oppression and retaliation. The unique element of this world is not magic, but deterministic tragedy—the inescapable pull of inherited will, historical guilt, and the devastating cost of freedom—making it a perfect foundation for a campaign rooted in survival horror, military drama, and morally gray decision-making without altering a single piece of canon.

The world of Attack on Titan is shaped by a stark divide between isolation and global domination, with geography directly reinforcing political power and historical trauma. At its center lies Paradis Island, a massive, resource-rich island long believed to house the last remnants of humanity. Paradis is defined by three colossal concentric Walls—Wall Maria, Wall Rose, and Wall Sina—which function simultaneously as fortifications, population control mechanisms, and instruments of enforced ignorance. Within these Walls are key urban centers such as Shiganshina District, a critical border city whose fall marks the beginning of the modern era of conflict; Trost District, a vital supply and military hub; and the Interior capital within Wall Sina, where the aristocracy and royal government once ruled in insulated decadence. Forests like the Forest of Giant Trees, mountainous terrain, and wide plains further influence military strategy, particularly for ODM-based combat and Titan containment operations. Beyond the sea lies the dominant global power of Marley, a militarized empire built on conquest and exploitation, whose authority is enforced through both conventional armies and the controlled use of Titan Shifters. Marley’s most significant city is Liberio, an internment zone where Eldians are segregated, indoctrinated, and weaponized, serving as both a population center and a living reminder of imperial oppression. Marley’s mainland geography—vast plains suitable for armored warfare, fortified ports, and expanding rail networks—reflects its industrial and imperial reach. Surrounding Marley are other unnamed global nations whose borders, alliances, and hostilities are shaped by fear of Titan warfare and resentment toward Eldian history, creating a tense international balance of power. Geographically, oceans serve as both barriers and revelations, with the sea surrounding Paradis acting as a literal and symbolic edge of the known world for much of history. Natural resources—especially iceburst stone, unique to Paradis—drive global interest and conflict, transforming geography into destiny. Mountains, coastlines, and fortified cities are not mere backdrops but active forces in shaping warfare, diplomacy, and survival. In this world, geography enforces isolation, empowers empires, and ensures that no kingdom or city exists without being deeply entangled in the legacy of Titans and the violence they bring.

The world of Attack on Titan is inhabited by only one biological species—humans, but it is divided into deeply entrenched ethno-historical groups whose relationships define the entire global conflict. Foremost among these are the Eldians, a people descended from Ymir Fritz and uniquely capable of transforming into Titans. This single biological distinction has shaped centuries of warfare, fear, and persecution. Eldians exist in two primary territories: on Paradis Island, where they were isolated behind the Walls and stripped of historical memory, and across the mainland under foreign rule—most notably within Marley—where they live as an oppressed underclass. Though biologically human, Eldians are treated globally as a dangerous “race,” feared not for who they are, but for what they can be forced to become. The Marleyans are the dominant political and military power of the modern world and represent the ruling human population of Marley. They possess no innate Titan abilities, yet they control Titan warfare by subjugating Eldians, turning them into living weapons through forced inheritance and punishment. Marleyans occupy the mainland’s industrial cities, military strongholds, and ports, while confining Eldians to internment zones such as Liberio, where strict segregation, propaganda, and indoctrination reinforce a narrative of Eldian guilt. The relationship between Marleyans and Eldians is one of systemic exploitation: Marley frames itself as humanity’s protector while perpetuating the same cycle of oppression it claims to oppose. Beyond Marley and Paradis lie other human nations, technologically advancing states that neither possess Titan powers nor share Marley’s historical dominance. These nations largely define Eldians as a global threat and view Marley as a necessary—if dangerous—hegemon capable of containing Titan warfare. Their territories are marked by fortified borders, expanding militaries, and growing resentment toward Marley’s reliance on Titans, which increasingly destabilizes global politics. While these nations are ethnically and culturally diverse, they are united by fear of Eldians and the legacy of the ancient Eldian Empire, making diplomacy fragile and war inevitable. In this world, race is not a matter of biology but of history weaponized. Eldians are simultaneously human, victims, and existential threats in the eyes of the world, while non-Eldians define themselves by their distance from Titan power. Territories are shaped not by natural borders alone, but by fear, propaganda, and inherited memory—ensuring that no group exists without being bound to the long shadow cast by the Titans.

The world of Attack on Titan is defined by escalating political tensions that turn every border, alliance, and secret into an opportunity for perilous adventure. The most immediate and volatile conflict is between Paradis Island and Marley, following the collapse of Paradis’ isolation and the revelation that the “enemy Titans” were tools of foreign powers. Marley’s public declaration of war against Paradis transforms the island from a forgotten prison into a global flashpoint, creating constant opportunities for covert operations, espionage, sabotage, and battlefield engagements as both sides race to secure resources, intelligence, and Titan powers. Internally, Paradis itself is fractured by ideological schisms that make the island as dangerous politically as it is militarily. The rise of extremist factions—most notably the Yeagerists—creates civil unrest, coups, and purges within the military and government. Loyalty to the crown, the military, or radical visions of freedom becomes a matter of life and death, offering fertile ground for adventures centered on political intrigue, moral dilemmas, prison breaks, assassinations, and desperate attempts to prevent civil war. Players may find themselves navigating secret police remnants, competing military branches, or underground resistance networks while Titans remain an ever-present threat beyond the Walls. On the global stage, Marley’s weakening dominance introduces new instability. Other nations, long subjugated or threatened by Marley’s Titan-based warfare, begin rapid militarization and secret weapons development, fearing both Marley and the unchecked potential of Paradis. Diplomatic missions, proxy wars, and clandestine arms races unfold as the world edges toward a post-Titan era. Adventurers may be sent to infiltrate enemy nations, protect or assassinate key political figures, disrupt Titan research programs, or escort defectors whose knowledge could shift the balance of power. Above all looms the ultimate existential threat: the Rumbling—the release of countless Colossal Titans hidden within the Walls. Whether as an imminent danger, a political deterrent, or a moral line about to be crossed, the Rumbling casts a shadow over every decision. Entire campaigns can revolve around preventing its activation, exploiting the fear it generates, or surviving in a world already reshaped by its devastation. In this setting, adventure is born from tension itself—where history, ideology, and apocalyptic power collide, and every choice risks triggering consequences that can doom nations or redefine humanity’s future.

In the world of Attack on Titan, magic does not exist in any conventional sense. There are no spells, mana, gods granting miracles, or supernatural races. Instead, what appears miraculous is the result of a biological–metaphysical system rooted in a single origin: the power of the Titans. This power manifests through a phenomenon known as Paths, an invisible dimension that connects all Subjects of Ymir across time and space. Through Paths, matter is constructed, memories are transmitted, and will itself can be inherited. Though it functions like magic from a narrative perspective, it is treated in-universe as an immutable law of nature—ancient, poorly understood, and terrifyingly absolute. Only Subjects of Ymir—a specific lineage of humans descended from Ymir Fritz—can access this power. Among them, a small number become Titan Shifters, inheriting one of the Nine Titans and gaining the ability to transform at will, regenerate, and wield specialized abilities tied to their specific Titan. These powers are governed by rigid rules: a thirteen-year lifespan after inheritance, memory bleed from past holders, physical and psychological degradation, and transfer only through consumption. The most powerful of these abilities belongs to the Founding Titan, which can alter memories, control Titans, and even reshape Eldian biology—but only under strict conditions tied to royal blood or specific circumventions of that restriction. This ensures that power is never free, never safe, and never without consequence. There are no true deities influencing the world in an active or benevolent sense. Ymir Fritz herself occupies a liminal role—revered by some as a god, condemned by others as a devil—but she is neither worshipped nor omnipotent in the traditional sense. Her presence persists within Paths as a tragic, enslaved force bound by obedience rather than divine will. Religious belief exists culturally, often weaponized by states like Marley for propaganda, but it holds no real metaphysical authority. There are no prayers that summon aid, no divine judgment beyond human action, and no cosmic morality enforcing justice. What makes this system uniquely suited for a campaign is that power replaces magic, and consequence replaces divinity. Abilities are rare, inherited, and politically explosive. Knowledge of how the system works is as dangerous as the power itself. Characters do not ask what spells they can cast—but what they are willing to sacrifice, whom they are willing to condemn, and how much of their humanity they are prepared to lose in a world where the closest thing to “magic” is a curse passed down through blood and history.

In the world of Attack on Titan, there are no multiple planes of existence in the traditional fantasy sense—no heavens, hells, elemental realms, or spirit worlds that characters travel between. However, there exists a single, unique metaphysical realm known as Paths, which functions as the only non-material plane and serves as the hidden framework underpinning reality itself. Paths is not a place one can physically journey to by conventional means, nor is it governed by gods or natural law as mortals understand it. Instead, it is an omnipresent, timeless dimension that connects all Subjects of Ymir across space and history, acting as both conduit and archive for Titan power. Paths interacts with the material world constantly but invisibly. Every Titan transformation, regeneration, memory inheritance, and biological alteration is enacted through Paths. When a Titan body forms, it is not grown in real time; it is constructed instantly through Paths, with matter seemingly transmitted from elsewhere, accompanied by the signature lightning strike. Memories of past Titan holders flow backward and forward through this realm, allowing the past to influence the present and, in rare cases, the future. Unlike other planes in fantasy settings, Paths does not obey linear time—events echo across generations, making fate feel predetermined and reinforcing the world’s central theme of inescapable causality. Interaction with Paths is extremely limited and exclusive. Ordinary humans have no awareness of it whatsoever. Even most Eldians experience it only subconsciously through inherited instincts or fragmented memories. Direct perception or influence over Paths is reserved almost entirely for the holder of the Founding Titan, and even then, only under very specific conditions. Within Paths resides Ymir Fritz, not as a goddess ruling a divine realm, but as a bound, tragic existence whose labor sustains the Titan system itself. Her presence gives Paths a haunting, almost spiritual quality, yet it remains fundamentally a prison rather than an afterlife. Crucially, Paths does not offer escape from death, resurrection, or communion with spirits. There is no confirmed afterlife, no souls returning to guide the living, and no cosmic justice beyond human action. Paths exists solely to perpetuate Titan power and inherited will, not to comfort or judge. For a campaign, this means that the metaphysical realm is not a playground for exploration, but a terrifying certainty—a reminder that the world is governed by unseen forces that cannot be bargained with, only endured or dismantled. The interaction between Paths and the material world reinforces the setting’s fatalism: history, power, and suffering are all inextricably linked, flowing endlessly through a realm that touches everything yet belongs to no one.

The history of Attack on Titan is divided into distinct eras, each leaving behind legacies and scars that continue to shape the present world. The earliest and most influential period is the Age of Ymir Fritz, beginning over two thousand years ago when Ymir Fritz first gained the power of the Titans. During this era, the Eldian people rose from obscurity to dominance, using Titan power to conquer neighboring lands and establish the vast Eldian Empire. Though little physical architecture from this age remains intact, its legacy survives through inherited memories, Titan abilities, and the enduring global fear of Eldian supremacy. This era defines the world’s foundational sin: conquest enforced not by gods or magic, but by living weapons bound to bloodlines. Following this came the Age of Eldian Rule, a millennium-long period during which the Eldian Empire dominated much of the known world. Countless cities were razed, cultures erased, and nations subjugated under Titan warfare. While the empire eventually fractured due to internal conflict among the Nine Titans, its ruins are scattered across the mainland—collapsed fortresses, buried cities, and forgotten battlefields now claimed by later nations. These remnants are rarely preserved with reverence; instead, they are feared, destroyed, or repurposed, as they symbolize oppression and inherited guilt rather than glory. The collapse of Eldian dominance ushered in the Great Titan War, a catastrophic civil conflict in which Eldian houses turned their Titans against one another. This war culminated in the rise of Marley as a global power and the retreat of the Eldian king to Paradis Island, where he erected the three Walls and erased the memories of his people. The legacy of this era is one of deliberate forgetting: the Walls themselves stand as the greatest ruin and monument of the past, built from countless Colossal Titans and hiding the truth of history in plain sight. Beneath Paradis lie abandoned cities, old fortifications, and sealed royal chambers—remnants of a forgotten world whose existence contradicts the lies the population lived under for generations. The most recent era, often called the Age of the Walls, is defined by isolation, stagnation, and survival against Titans believed to be humanity’s only enemy. Ruins from this time are more intimate: destroyed districts like Shiganshina, abandoned towns reclaimed by Titans, and battle-scarred landscapes shaped by ODM warfare. These ruins are not ancient relics but fresh wounds, constantly reminding humanity of its vulnerability and ignorance. As the Walls fall and the truth of the world is revealed, all previous eras collide—ancient sins, suppressed history, and modern warfare converging into a single, inescapable legacy. In this world, ruins are not merely physical structures; they are historical lies made visible. Every fallen city, buried fortress, and sealed memory reinforces the central truth of the setting: the past was never gone—it was waiting, patiently, for humanity to remember it.

In Attack on Titan, civilization is sustained not by fantastical wealth or arcane markets, but by controlled scarcity, militarized production, and state-directed economies shaped by perpetual war. Currency exists in conventional forms—coinage and paper money—but its value is tightly bound to food supply, military demand, and state authority rather than free trade. Within Paradis Island, the economy during the Age of the Walls is largely closed and insular, centered on agriculture, rationing, and internal redistribution. Land ownership inside the inner Walls concentrates wealth among nobles and merchants aligned with the former royal government, while outer districts function as expendable breadbaskets and manpower reserves. Economic mobility is limited, and military service—particularly in the Scout Regiment—is one of the few paths to status or state support, reinforcing a system where survival and patriotism replace profit. Trade routes within Paradis are strictly internal for most of its history. Goods move radially from agricultural zones near Wall Maria and Rose toward the interior, supplying the capital and elite districts of Wall Sina. After the fall of Wall Maria, these routes collapse under refugee pressure, food shortages, and inflation, creating black markets, smuggling rings, and corruption that thrive in moments of crisis. Following the overthrow of the old monarchy and the rediscovery of the outside world, Paradis’ economy begins a rapid, uneven transition toward military-industrial production, driven by the exploitation of iceburst stone, a rare natural resource unique to the island that powers advanced technology such as ODM gear and experimental weapons. This single resource transforms Paradis from an isolated backwater into a target of global economic and military interest. On the mainland, Marley operates a far more expansive and aggressive economic system rooted in imperial extraction and industrial warfare. Marley’s currency and markets are stabilized through conquest, colonial control, and forced labor—particularly Eldian labor within internment zones like Liberio. Trade routes span rail networks, fortified ports, and occupied territories, moving raw materials, weapons, and military supplies to fuel Marley’s dominance. Titans themselves function as economic instruments: their deployment reduces the need for prolonged campaigns, lowers costs of occupation, and intimidates rival nations into compliance. However, as global technology advances and anti-Titan weapons proliferate, Marley’s Titan-centered economy begins to strain, accelerating arms races and destabilizing its financial foundations. International trade beyond Marley and Paradis is cautious and heavily politicized. Other nations maintain commerce through guarded sea lanes and rail corridors, trading conventional goods while avoiding dependence on Titan-powered states. Fear dictates economics: nations invest more in fortifications and weapons than in prosperity, and alliances form not around mutual benefit, but around shared threats. As Paradis re-enters the world stage, its resources, strategic position, and latent Rumbling capability turn every potential trade agreement into a diplomatic gamble. Overall, the economic systems of this world are subordinate to survival and power. Wealth is meaningless without security, trade exists only where force allows it, and entire populations are reduced to resources to be spent. For a campaign, this creates fertile ground for stories involving ration riots, smuggling operations, industrial espionage, resource wars, labor revolts, and high-stakes diplomacy—where coin and contracts matter far less than who controls food, fuel, and the weapons that decide humanity’s fate.

In Attack on Titan, justice is not an impartial ideal but a tool of state survival, enforced through military authority rather than civil law. On Paradis Island during the Age of the Walls, justice is administered primarily by the Military Police Brigade, whose mandate is to preserve internal order, protect the ruling class, and suppress dissent. Trials are rare, opaque, and often predetermined; confessions are coerced, evidence is controlled, and executions or disappearances are common outcomes for those deemed threats to stability. The monarchy and later the provisional government rely on secrecy and fear, making justice less about truth and more about maintaining the illusion of peace. After the political upheaval that overthrows the false royal regime, justice becomes more fragmented—still militarized, but increasingly shaped by emergency rule, internal purges, and ideological loyalty tests rather than codified law. Beyond the Walls, Marley administers justice with even greater brutality and efficiency. In Marley, legal systems exist in name but function almost entirely as instruments of ethnic control and imperial discipline. Eldians are judged under separate, far harsher standards, with collective punishment, public executions, and forced Titanization used as legal penalties. Courts serve propaganda purposes, reinforcing narratives of Eldian guilt and Marleyan righteousness. Justice in Marley is swift, public, and exemplary—designed to deter rebellion rather than deliver fairness. Other global nations mirror aspects of this system, prioritizing national security over individual rights in a world perpetually on the brink of annihilation. Society’s view of “adventurers”—those who venture beyond safe borders, uncover forbidden truths, or operate independently of state control—is deeply conflicted. On Paradis, members of the Scout Regiment occupy this role, and for much of history they are viewed with a mixture of contempt and grim respect. Civilians often see them as reckless, doomed idealists wasting lives and resources, while the state uses them as expendable tools to probe the unknown. Only after major revelations and victories do Scouts gain widespread admiration, and even then, their heroism is inseparable from trauma, loss, and political exploitation. Adventurers are not celebrated wanderers; they are soldiers sent where survival is least likely. In the wider world, independent actors are viewed with suspicion or outright hostility. Mercenaries, defectors, spies, and rogue operatives are tolerated only when they serve state interests and eliminated the moment they become inconvenient. There is no romantic notion of adventuring for glory or wealth—anyone operating outside official command structures is assumed to be a destabilizing force, a potential revolutionary, or a weapon to be seized. Knowledge itself is dangerous, and those who seek it are often hunted. Ultimately, justice in this world is reactive, authoritarian, and conditional, while adventurers are seen not as heroes by default, but as necessary risks. Their worth is measured solely by results—territory reclaimed, enemies destroyed, truths suppressed or revealed. For a campaign, this creates a powerful dynamic: characters are never protected by law or legend, only by usefulness. Survival, legitimacy, and morality are constantly in tension, ensuring that every action carries legal, political, and existential consequences.

In Attack on Titan, the greatest threats to civilization are not monsters born of myth, but human-made horrors—creatures, ideologies, and inherited powers that blur the line between weapon and curse. Foremost among these are the Pure Titans: mindless, immortal giants created when Subjects of Ymir are forcibly transformed. They roam endlessly, driven only by an instinct to devour humans, turning vast regions into uninhabitable dead zones. Though individually simple, their numbers, durability, and unpredictability make them an existential menace to any unprotected settlement, shaping borders, migration, and military doctrine wherever they appear. Above them stand the Nine Titans, intelligent and uniquely empowered beings whose abilities—armored fortresses, colossal destruction, adaptive evolution, future memory inheritance—can alter the fate of nations. These Titans are not evil by nature, but their existence concentrates unimaginable power into individual hands, ensuring that every succession is a political crisis and every bearer a strategic target. The curse bound to them—the thirteen-year lifespan and erosion of self through inherited memories—turns each Titan into a ticking catastrophe, where personal will steadily dissolves into historical momentum. More insidious than any creature are the ideological cults and state religions that grow around Titan power. In Marley, Titan ideology is institutionalized: Eldians are indoctrinated to view themselves as sinful descendants whose only redemption lies in serving the state as weapons. This belief system functions as a living cult, justifying genocide, forced transformation, and inherited warfare under the guise of global protection. On Paradis, opposing extremist movements arise—factions that elevate Titan power as the only path to freedom, embracing annihilation over coexistence. These groups are not ancient orders with hidden temples, but modern cults of desperation, born from fear and historical trauma. The most terrifying “ancient evil” is neither creature nor god, but a system that cannot forget. The metaphysical network of Paths ensures that violence, memory, and will are never truly buried. Through it, the past exerts constant pressure on the present, compelling individuals to repeat the same cycles of conquest and retaliation. The ultimate manifestation of this threat is the Rumbling—the potential release of countless Colossal Titans hidden within the Walls, capable of erasing civilization on a global scale. It is not a prophecy or a demon’s awakening, but a man-made apocalypse, deliberately constructed and waiting only for the resolve to be unleashed. In this world, threats do not come from the unknown—they come from what humanity already built. Titans are weapons that outlived their creators, ideologies are prisons masquerading as salvation, and ancient evils persist not as monsters in ruins, but as decisions inherited across generations. For a campaign, this means every enemy carries moral weight: slaying a Tit
