Fantasy Writing Prompts: Geography Edition

A comprehensive Writing Prompts for Fantasy writers working on Geography. Free worldbuilding resource from Obsidian Tavern.

Geography in fantasy isn't just backdrop—it's a living character that shapes cultures, drives conflict, and creates the unique challenges only magical worlds can offer. These prompts will help you craft landscapes that feel both fantastical and believable, where every mountain range tells a story and every river holds secrets.

1

Design a continent where the cardinal directions have fundamentally different magical properties. North might drain magic, South might amplify it, East could twist spells unpredictably, and West might preserve magic indefinitely.

Consider how this would affect trade routes, where different magical schools would establish themselves, and how cultures would develop differently based on their geographical position. Think about border regions where these effects blend or conflict.

Genre twist: A diplomatic crisis erupts when a powerful artifact must be transported from the magic-draining North to the magic-amplifying South, but the only safe route passes through three different kingdoms that each want to claim it during transport.
2

Create a mountain range that grows and shifts based on the collective emotions of the people living in its shadow. Joy makes peaks rise higher, despair causes valleys to deepen, anger creates unstable rockslides, and fear opens new cave systems.

Map out how settlements would adapt to this emotional geography. Consider the role of community leaders, festivals, and conflict resolution. How would architects design buildings for constantly shifting terrain? What would mining or agriculture look like?

Genre twist: An ancient evil buried beneath the mountains can only break free if the peaks reach a certain height through sustained joy—but the kingdom above desperately needs that happiness to recover from a plague of despair.
3

Design a region where gravity flows like water, pooling in valleys and creating rapids of intense gravitational pull while leaving some hilltops in near-weightlessness.

Think about how this affects everything from agriculture (do crops grow down into gravity pools?) to architecture (buildings anchored against gravity streams). Consider unique weather patterns, specialized transportation, and how different species might evolve here.

Genre twist: A gravity storm is approaching that will completely redistribute the gravitational landscape, and three competing factions each want to position their territories to benefit from the new flow patterns.
4

Build a coastal region where the tide doesn't just move water in and out, but cycles through different elemental states—water tide, earth tide (fertile soil flows like liquid), fire tide (flowing lava that cools to form temporary land), and air tide (dense atmosphere that can be walked on briefly).

Consider the complex ecosystem that would develop, the seasonal patterns, and how coastal communities would time their activities. What unique resources would each tide bring? How would shipping and fishing adapt to four different ocean states?

Genre twist: The elemental tide cycle is being disrupted by an underwater ritual site, causing tides to come out of sequence and threatening to permanently flood some areas while leaving others in eternal drought.
5

Create a forest where each tree species represents a different biome—desert palms create zones of arid heat, arctic pines radiate cold, and jungle trees produce their own weather systems, all within a few hundred yards of each other.

Map the microclimates and consider how wildlife moves between them. Think about specialized gear travelers would need, how druids or forest guardians would navigate between biomes, and what resources each zone provides.

Genre twist: The forest is actually a living map of a shattered world, and if someone can navigate to the correct sequence of biome-trees and perform a ritual in each, they might be able to restore the original world—but others seek to prevent this restoration.

How to Use These Prompts

Start by sketching rough maps even if you're not an artist—spatial relationships matter more than pretty drawings. Always ask 'how do people actually live here?' rather than just focusing on the magical spectacle. Remember that unusual geography creates unusual solutions, so let your characters develop technologies, customs, and skills that make sense for their specific landscape challenges.

Great fantasy geography doesn't just look impossible—it feels inevitable once you understand the rules. Let your landscapes be active participants in your story, not just stages for your characters to perform upon.
