World-Building Guide
The World-Building Guide generates a detailed, internally consistent fictional world for novels, short story collections, tabletop RPG campaigns, screenplays, or video game narratives. It produces the foundational elements that make fictional settings feel lived-in: geography that shapes culture, history that explains current conflicts, economies that drive character motivations, and belief systems that create moral complexity.
Fantasy and science fiction writers, game designers, tabletop RPG dungeon masters, and screenwriters building speculative fiction use this template. It is particularly valuable at the start of a project when you need to establish the rules and texture of your world before writing scenes, or mid-project when you realize your setting needs more depth to support the story.
This prompt produces richer worlds than a generic "create a fantasy world" request because it enforces interconnection between world elements. Geography influences economy; economy shapes class structure; class structure drives political tension; political tension creates the conflicts your characters inhabit. It also includes a consistency check section that flags potential contradictions, preventing the worldbuilding errors that pull readers out of a story.

The Prompt
Generate a comprehensive world-building document for a fictional setting based on these parameters: **Genre**: [GENRE, e.g., "High fantasy", "Space opera", "Post-apocalyptic", "Steampunk", "Urban fantasy", "Alternate history"] **Scale**: [SCOPE, e.g., "A single city-state", "A continent with 5 nations", "A solar system with colonized planets", "A single generation ship"] **Tone**: [TONE, e.g., "Gritty and realistic", "Epic and mythic", "Darkly humorous", "Wonder-filled and optimistic"] **Central Conflict** (optional): [THE BIG TENSION, e.g., "A declining empire vs. rising republics", "Magic is fading and no one knows why", "First contact between two civilizations"] **Inspirations** (optional): [TOUCHSTONES, e.g., "Medieval West Africa meets Greek mythology", "Victorian London if the industrial revolution ran on alchemy", "The Roman Empire in space"] Generate the following world-building elements: ### 1. Geography and Environment - Physical landscape: terrain, climate zones, natural resources, notable landmarks - How geography shapes trade routes, borders, and cultural divisions - Environmental threats or phenomena unique to this world - A brief description of 3-4 key locations (a major city, a wilderness, a border region, a sacred or forbidden place) ### 2. Peoples and Cultures For each major culture or species (2-4): - Name, physical characteristics (if non-human), population center - Core values and beliefs: what do they consider admirable? Shameful? - Social structure: how are power, wealth, and status distributed? - Distinctive customs, art forms, or daily life details that make them feel real - Relationship with other groups: alliances, rivalries, trade, prejudice ### 3. Magic System, Technology, or Unique Mechanic - What makes this world different from our own (magic, advanced tech, altered physics, supernatural elements)? - Rules and limitations: what can it do, what can it not do, and what does it cost? - Who has access (everyone, a select few, a particular class)? - How it shapes society: economic impact, warfare, daily life, social hierarchy - Unintended consequences or ethical dilemmas it creates ### 4. History and Timeline - Origin story or creation myth (what the people believe) - 4-6 major historical events that shaped the current era - A recent event (within living memory) that is still causing ripples - What historical grudges, debts, or alliances are active in the "present day"? ### 5. Political and Economic Systems - How is power organized (monarchy, council, theocracy, corporate oligarchy, tribal federation)? - What is the basis of the economy (trade, agriculture, mining, magic, information)? - Who has power and who lacks it? What tensions does this create? - Current political crisis or instability that could drive a story ### 6. Belief Systems and Mythology - Dominant religion(s) or philosophical traditions - How do supernatural/spiritual beliefs interact with the magic system or technology? - Heretical or minority beliefs that challenge the mainstream - Rituals, holidays, or practices tied to these beliefs ### 7. Story Seeds Based on the world you have built, suggest 3 compelling story premises that could only happen in this specific world. Each should combine personal stakes with world-level conflict. ### 8. Consistency Check Review the world for internal contradictions. Flag any elements that conflict with each other and suggest resolutions. For example: "If the northern kingdom controls all the iron mines, how does the southern republic sustain a standing army? Possible resolution: they have developed bronze alloy alternatives or rely on mercenary companies."
Usage Tips
- Start with your central conflict: The most useful worlds are built to serve a story. If you know your main conflict, the AI designs geography, politics, and magic systems that amplify that conflict naturally.
- Use the inspirations field to avoid generic settings: "Medieval Europe" produces a generic fantasy world. "14th-century Malian Empire meets Norse mythology" produces something distinctive. Mash up unexpected influences.
- Drill deeper after the initial generation: Pick the most interesting element and ask follow-up questions: "Expand the magic system with 5 specific spells and their costs" or "Write a 500-word scene set in the border market town."
- Use the consistency check as a revision tool: The contradictions the AI flags are often the most interesting parts of your world. Some contradictions should be resolved; others should become plot points.
- Build incrementally across sessions: Start with one generation, then come back and say "Here is my world doc. Now add a detailed criminal underworld for the capital city." Layer complexity over multiple sessions.
