Top 17 'God-Mode' World-Building Prompts to Explore at Home for Aspiring Fantasy Authors and Game Masters - Goh Ling Yong
Every aspiring author or Game Master knows the feeling. You sit down, brimming with excitement, ready to create a new world. You open a fresh document or unroll a blank sheet of parchment, and then... nothing. The sheer, overwhelming possibility of it all can be paralyzing. Where do you even begin? With a map? A character? A magic system?
This creative paralysis is the great dragon that guards the hoard of your imagination. While top-down (starting with the cosmos and zooming in) and bottom-up (starting with a single village and zooming out) approaches are valid, sometimes you need a different key to unlock the door. You need a spark, a single, compelling question that sends ripples across the entire canvas of your world.
That’s what this list is for. These aren't your standard "Design a continent" prompts. These are 'God-Mode' prompts—foundational ideas that, once decided, will dictate the very nature of your world's geography, cultures, conflicts, and magic. They are catalysts designed to make world-building an exciting act of discovery rather than a chore. So grab a notebook, fire up your favorite writing software, and let's start playing god.
1. The Scar on the World
Every world has a history, but the most interesting worlds wear that history on their sleeve. Imagine a single, cataclysmic event from your world's past so massive that it left a permanent physical mark. This isn't just a ruined city; it's a continental feature. Was it a magical war that boiled a sea, leaving a crystalline desert? Did a god fall from the heavens, their colossal body forming a new mountain range from which strange energies now emanate?
This "scar" becomes the nexus of your world-building. The politics of the nations bordering the "God-Fall Mountains" will be entirely different from those on the other side of the world. The scar could be the source of all magic, a cursed wasteland everyone fears, or a modern-day gold rush for adventurers seeking powerful artifacts.
Examples & Tips: Consider a massive chasm that splits a continent, known as the "World-Wound," which constantly bleeds raw, chaotic magic. Or perhaps a region where the sky is permanently shattered, with chunks of other realities floating amidst the clouds. Ask yourself: Who or what caused it? Are there people who live within the scar? What strange flora and fauna have adapted to its unique environment?
2. A Truly Alien Ecology
We often default to fantasy ecologies based on Earth: forests of oak, plains of grass, mountains of granite. But what if the fundamental building blocks of life were different? This prompt challenges you to design a world where the dominant life forms aren't mammalian or even carbon-based. Imagine a world of sentient, crystalline beings, or a planet where vast, interconnected fungal networks form the basis of all intelligence.
This single decision radically alters everything. How would a society of silicon-based lifeforms build their cities? What would war look like between a fungal hivemind and a race of mobile, sentient coral? This pushes you beyond reskinning classic fantasy tropes and forces you to think about how environment shapes culture, technology, and biology from the ground up.
Examples & Tips: A forest made of massive, slowly shifting glass-like flora. A swamp populated by creatures made of living shadow and sound. A desert where the dunes are not sand, but the metallic spores of a planet-spanning fungus. Think about the food chain, resource gathering, and what "shelter" even means in this environment.
3. The Banned Art or Science
Conflict is the engine of story. A fantastic way to build inherent conflict into your world is to forbid a specific field of knowledge. Necromancy is the classic example, but you can go deeper. What if clockwork automation was banned by powerful artisan guilds who fear being replaced? What if the ability to read and write is a secret held only by a religious caste, punishable by death for commoners?
This creates immediate tension and power dynamics. Who enforces the ban, and what is their motivation? Is it for the good of society, or to maintain their own power? This also gives you a built-in "underworld" of secret practitioners, rebel scholars, and forbidden artifacts. Your players or protagonists might be part of this underground, or they could be the enforcers hunting them down.
Examples & Tips: Forbid "Chronomancy" (time magic) because a past disaster nearly unraveled reality. Ban the printing press to control the flow of information. Outlaw "empathy magic" because it was once used by a tyrant to emotionally enslave entire nations.
4. The Symbiotic City
Where people live says a lot about them. Take this to the extreme by having a major city built on or in harmony with a colossal, living creature. This isn't just a town next to a forest; the city and the creature are part of a single, functioning system. Are the buildings carved from the shell of a gargantuan, continent-sized turtle that slowly swims across the ocean? Is the city nestled in the branches of a tree so large its canopy creates its own weather system?
The relationship between the people and the creature is the core of this society's culture. Do they worship it as a god, tend to it like a beloved pet, or exploit it like a resource? What happens if the creature gets sick, decides to move, or dies? This creates a unique and visually stunning location that is inherently fragile and full of story hooks.
Examples & Tips: A mining town built on the back of a slumbering, mountain-sized elemental, extracting rare minerals from its skin. A port city woven into the body of a giant floating jellyfish. A nomadic culture that follows a herd of titanic land-whales, setting up temporary settlements on their backs.
5. Unseasonal Weather
In our world, seasons are predictable. What if they weren't? What if your world’s weather patterns were governed by something other than planetary tilt? Perhaps the seasons change based on the proximity of a magical moon, causing a "season of weightlessness" or a "season of silence." Maybe the rain itself is magical, with different colored storms bringing different effects—red rain that spurs rapid growth, gray rain that dulls emotions.
This affects every aspect of daily life. Agriculture would be completely different, revolving around predicting and surviving bizarre weather events. Architecture would be designed to withstand rains of glass or winds that carry ghosts. Festivals and religious ceremonies would be dedicated to appeasing whatever forces control the bizarre and unpredictable climate.
Examples & Tips: A world with two suns, one of light and one of shadow, that create a cycle of normal day and a "dark day." A phenomenon known as "Memory Fog" that rolls in from the sea, causing those within it to relive powerful memories. A yearly "Storm of Chaos" where the laws of physics become temporarily unreliable.
6. The Precursor's Leftovers
Your world is not the first. Long before the current civilizations arose, there was another—a precursor race that was far more advanced, either magically or technologically. Now they are gone, leaving only enigmatic ruins and dangerously powerful artifacts behind. The world is built, quite literally, on top of their lost civilization.
The nature of these precursors defines the "ancient history" and "dungeon-crawling" aspects of your world. Are their ruins sleek, metallic structures humming with forgotten science, or are they impossible geometries carved from single pieces of obsidian that pulse with magical energy? The current inhabitants might fear these places, plunder them for profit, or try to reverse-engineer the lost technology, creating a fascinating blend of old and new.
Examples & Tips: The precursors were masters of bio-engineering, and their "ruins" are actually living, self-repairing organisms. They were reality-benders, leaving behind areas where gravity is inverted or time flows backward. A modern city might be built around a precursor power source they don't fully understand, making life both convenient and precarious.
7. Magic with a Painful Price
In many fantasy settings, magic is a convenient tool with few downsides. Make it more interesting by giving it a clear, tangible, and terrible cost. Using magic might drain the caster's life force, slowly eroding their body. Perhaps it requires consuming rare and exotic components, or it pollutes the very land it's used on, creating magical wastelands.
This turns magic from a simple skill into a resource to be managed and a source of ethical dilemmas. A society where magic costs memories would view its mages with a mixture of awe and pity. A kingdom powered by magic that poisons the earth would face a constant struggle between progress and survival. Like many of the creative exercises we discuss on Goh Ling Yong's blog, this is about adding consequence and depth to a fantastical idea.
Examples & Tips: Magic draws its power from emotion, but using it "burns out" the caster's ability to feel that emotion ever again. Magic is a form of debt to otherworldly entities who will one day come to collect. Each spell cast creates a "magical echo," a spectral copy of the effect that will unpredictably manifest again days or weeks later.
8. The One True Commodity
Forget gold and silver. Your world's economy, politics, and wars are driven by a single, unique, and vital commodity. This resource is essential for magic, technology, longevity, or even basic survival. Control of this resource means control of the world.
This central commodity gives your world an instant global conflict. Who has it? Who wants it? How is it harvested or created? What lengths will people go to in order to secure their supply? It becomes the "spice" of your setting, influencing everything from trade routes and national alliances to the daily lives of common people.
Examples & Tips: "Sun-crystals," solidified pieces of sunlight that are the only source of light and heat in a subterranean world. "Aetherium," a lighter-than-air metal required for the construction of flying ships. "Somnus Pollen," a flower byproduct that allows mages to enter and shape the dreams of others.
9. A World Without Metal
Imagine a Bronze Age or Iron Age that never happened. How would societies develop without access to metal? This simple constraint forces incredible creativity. How do you build a skyscraper, forge a weapon, or create fine tools without steel, iron, or even copper?
This prompt leads to unique aesthetics and technologies. Warriors might use weapons made of magically hardened wood, sharpened obsidian, or the bones of massive beasts. Armor could be crafted from giant insect chitin or intricately woven, magically-treated fibers. Architecture would rely on masterful stonemasonry, organic shaping of living trees, or alchemically-strengthened ceramics.
Examples & Tips: A culture that has perfected glass-working, creating weapons and tools of surprising resilience. A society of druids who can magically shape and harden wood into a material stronger than steel. A civilization that uses domesticated, acid-spitting creatures to carve their homes directly from the mountainside.
10. Gods Who Walk Among Us
The gods of your world are not distant, ethereal beings. They are tangible, physical entities who walk the mortal plane. They might run a tavern in a backwater village, serve as advisors to kings, or get into petty squabbles that level entire city blocks.
This changes the nature of faith completely. Religion isn't about belief; it's about direct interaction and reputation. A cleric's power might come not from prayer, but from being on a first-name basis with their deity. This also introduces immense chaos. What happens when the God of War gets bored and decides to "liven things up"? How do you prosecute a God of Thieves who keeps robbing the royal treasury?
Examples & Tips: The gods are bound by an ancient pact to not use their full power, forcing them to achieve their goals through mortal agents and subtle influence. There is only one god for each domain (one god of the sea, one of smithing, etc.) and if they die, a mortal can ascend to take their place, leading to a world of divine assassins and aspirants.
11. The Inverted Hierarchy
Challenge classic social structures by inverting them. Take a group or class that is traditionally at the bottom of the social ladder and put them at the very top. Perhaps in a city plagued by a magical, sentient filth, the sanitation workers (who control the slimes that eat it) are the most revered and powerful guild. Maybe only children can safely wield a certain type of powerful magic, making them the rulers, advised by a council of adult "regents."
This creates a fascinating and unique culture with its own set of problems and social norms. It allows you to explore themes of power, prejudice, and tradition from a completely new angle. How does the rest of society view these unlikely rulers? What unique customs and laws have developed around this inverted structure?
Examples & Tips: Farmers are the highest class because the soil is sentient and will only yield its bounty to those who can commune with it through generations of inherited bloodlines. The illiterate are the ruling class because an ancient curse causes written words to steal the sanity of those who can read them.
12. The Library of Whispers
The greatest repository of knowledge in your world isn't a collection of books. Information is stored in a much more exotic and interesting way. This "library" could be a vast, ancient forest where each tree holds the memories of a specific person or event. It could be a cavern where the whispers of the past echo eternally, decipherable only by trained listeners.
Accessing information in this world becomes an adventure in itself. You don't just check out a book; you might have to brave a dangerous forest, decipher a complex song, or convince a guardian spirit to share its secrets. This makes knowledge a living, breathing thing, and those who can access and interpret it hold immense power.
Examples & Tips: A library made of magically preserved tattoos on the bodies of immortal monks. A collection of "soul-jars," where the spirits of long-dead experts can be consulted. A vast desert where the winds carve the entire history of the world into the shifting sands.
13. Fantastic Transportation
How people and goods move around your world can define its scale, its economy, and its culture. Move beyond horses and sailing ships. What if the primary mode of long-distance travel was via a network of unstable, ancient teleportation gates? Or perhaps giant, domesticated insects are the beasts of burden and mounts for cavalry.
A unique transportation system creates unique infrastructure, jobs, and dangers. The "Gate-Menders Guild" would be incredibly powerful. A "Roc Tamer" would be a respected and high-risk profession. It shapes your map—cities would cluster around gate locations or along the migratory paths of the giant beasts they ride, rather than just on rivers and coastlines.
Examples & Tips: Sailing on seas of sand using special "skimmer" ships. Navigating magical ley-lines that crisscross the globe, a dangerous but fast method of travel. A system of trained, giant birds that carry passenger pods between mountain-top aeries.
14. The Known Afterlife
Imagine a world where the existence and nature of the afterlife is not a matter of faith, but a known, provable fact. It’s a physical place that, while difficult, can be traveled to by the living. You know exactly what happens when you die.
This fundamentally changes everything about society's relationship with life and death. The fear of death might be replaced by the fear of a boring or painful eternity. Religions would function less like churches and more like cosmic travel agencies, offering guidance and preparation for the "Great Journey." Murder takes on a new dimension when you aren't just ending a life, but sending someone to a specific place.
Examples & tips: The afterlife is a bleak, gray wasteland, leading to a culture obsessed with immortality and life-extension. There are multiple afterlives, and a person's deeds and beliefs determine which one they go to, creating intense religious competition. Necromancers aren't evil; they're specialists who can retrieve souls from the afterlife for questioning or a second chance.
15. The Dominant Sense
Our culture is overwhelmingly visual. We "see" what others mean, we "look" forward to things, we "watch" shows. Design a culture that is primarily based on a different sense, such as smell, sound, or touch. How would this change their language, art, and social customs?
For a society based on scent, names might be complex aromatic signatures, and social status could be conveyed by the perfumes one wears. For a sound-based culture, architecture would be built with acoustics in mind, and their music would be more complex and emotionally resonant than any painting. It's a challenging but rewarding prompt that can lead to a truly alien-feeling culture.
Examples & Tips: A subterranean race that navigates and communicates through echolocation, with "art" being the creation of complex "sound-scapes" in their cavern-galleries. A society where contracts and emotional states are communicated through intricate, touch-based gestures and textures.
16. The Unbreakable Law
Take one law of physics or magic and change it. This isn't a spell or a temporary effect; it's a fundamental, unbreakable rule of your reality. What if gravity in your world is tied to mass, but also to charisma, causing popular people to be literally more grounded? What if every lie ever told manifests as a physical, insect-like creature?
This kind of foundational change has endless ripple effects. A world where shadows have their own independent, and often malicious, life would have a completely different relationship with light and darkness. A world where emotions have a physical weight and can be stored in containers would revolutionize psychology, warfare, and even economics. The key is to think through the logical, and illogical, consequences of your one big change.
Examples & Tips: The law of "Emotional Combustion"—intense emotions can cause the person feeling them to literally catch fire. The law of "Sympathetic Synchronicity"—identical objects are mystically linked, so what happens to one happens to the other, making mass production incredibly dangerous.
17. The Great Pilgrimage
Cultures are often defined by their great journeys. Think of a journey that is central to the identity of at least one major culture in your world. This isn't just a trip; it's a rite of passage, a holy quest, or a necessary expedition for survival. The journey itself is more important than the destination.
Defining this pilgrimage helps you flesh out a huge swath of your world. What is the route? What dangers lie along the way—both monstrous and political? What shrines, traditions, and economies have sprung up along the path to support the pilgrims? This prompt provides a ready-made structure for a novel or a TTRPG campaign, giving the characters a clear goal and a path to follow. As an author, Goh Ling Yong often explores how a character's journey shapes their identity, and this prompt puts that concept on a societal scale.
Examples & Tips: A coming-of-age ritual where the young must walk the "Path of Echoes," a dangerous road through mountains that replay visions of the past. A pilgrimage to the heart of a magical forest to gather a seed that will only grow in their homeland, ensuring another cycle of life. A massive, nomadic trading caravan that follows the seasons, its route being the economic lifeblood of the entire continent.
World-building doesn't have to be a slow, methodical process of filling out checklists. By starting with one big, game-changing idea, you can let the details blossom naturally and logically from that central concept. The world starts to build itself, surprising you with connections and possibilities you never would have planned.
So pick a prompt that excites you. Run with it. Ask "what if?" over and over again. Don't be afraid to create something truly weird and wonderful.
Which of these prompts sparked an idea for you? Share the concept it ignited in the comments below—we'd love to see what kind of worlds you're building
