20 Geography Ideas for Fantasy Writers

A comprehensive Idea List for Fantasy writers working on Geography. Free worldbuilding resource from Obsidian Tavern.

Geography shapes every aspect of your fantasy world, from trade routes and political boundaries to cultural development and magical systems. The physical landscape doesn't just provide a backdrop—it actively drives plot, conflict, and character development while creating the authentic sense of place that makes fantasy worlds memorable. This collection focuses on creating geographically-driven storytelling opportunities that go beyond basic map-making.

Landscapes shaped by or infused with magical forces, creating unique environmental storytelling opportunities

Ley Line Convergences

Areas where magical energy lines intersect, creating zones of amplified power, reality distortion, or spontaneous magical phenomena. Cities built on convergences become centers of magical learning but suffer from unpredictable magical surges.

High Fantasy, Urban Fantasy

Petrified Battlefields

Ancient war sites where powerful magic turned combatants and landscape to stone mid-battle. These areas serve as haunting monuments, sources of ancient weapons/armor, and locations where old conflicts might literally come back to life.

Epic Fantasy, Dark Fantasy

Elemental Scars

Permanent geographical changes from massive elemental magic use—glass deserts from fire magic wars, floating earth chunks from earth magic battles, or perpetual storm zones from air magic conflicts.

High Fantasy, Elemental Magic Systems

Dream Bleed Zones

Regions where the boundary between dreams and reality has worn thin, causing the landscape to shift according to the subconscious minds of those present. Highly dangerous but potentially rewarding for those seeking lost knowledge.

Surreal Fantasy, Psychological Fantasy

Harsh or unusual landscapes that create survival challenges and unique cultural adaptations

Inverse Mountains

Massive chasms that plunge deep into the earth with 'peaks' pointing downward. Settlements cling to the walls at different depths, creating vertical societies with unique trade and communication challenges.

High Fantasy, Weird Fantasy

Tidal Forests

Woodlands that flood completely twice daily with massive tides, requiring tree-dwelling cultures and amphibious wildlife. The forest floor is accessible only at low tide, creating time-pressure exploration scenarios.

Coastal Fantasy, Environmental Fantasy

Gravity Wells

Areas where gravitational force varies dramatically—floating islands above high-gravity zones, waterfalls that flow upward, or regions where characters must adapt to crushing weight or weightlessness.

Weird Fantasy, Science Fantasy

Living Glaciers

Massive ice formations with their own consciousness that slowly migrate across continents. Settlements must constantly relocate, and the glacier's mood affects local weather and the behavior of ice-adapted creatures.

Arctic Fantasy, Primordial Fantasy

Landscapes defined by valuable or essential resources that drive conflict and economic systems

Mana Springs

Natural springs that restore magical energy, making them invaluable strategic resources. Control of springs determines magical power balances, and their seasonal flow creates predictable periods of magical abundance or drought.

High Fantasy, Magic-Dependent Societies

Bone Gardens

Vast fields where giant creature skeletons create cathedral-like structures. These areas provide materials for bone-working cultures and serve as natural amphitheaters for necromantic rituals or religious ceremonies.

Dark Fantasy, Necromantic Settings

Crystal Cavern Networks

Extensive cave systems lined with magical crystals that serve as natural communication networks, light sources, or spell components. Mining operations risk destabilizing the entire network's magical resonance.

High Fantasy, Underground Adventures

Phoenix Nesting Grounds

Circular valleys where phoenixes undergo their burning rebirth cycles, leaving behind valuable ash that promotes rapid plant growth and has alchemical properties. Access is dangerous but lucrative.

High Fantasy, Mythological Fantasy

Border regions and liminal spaces where different worlds, dimensions, or realities intersect

Season Borders

Physical boundaries where different seasons exist simultaneously—step across a stream and move from winter to summer instantly. These areas are often controlled by seasonal courts or nature spirits.

Fae Fantasy, Elemental Fantasy

Time Erosion Zones

Regions where time flows at different rates or directions, creating landscapes where ancient ruins exist alongside futuristic structures. Travelers may age rapidly or find themselves moving backward through time.

Temporal Fantasy, Weird Fantasy

Planar Overlap Islands

Floating landmasses that exist simultaneously in multiple planes of existence. Inhabitants can access different planes by moving to different areas of the island, but planar storms can shift the entire island between realities.

Planar Fantasy, Multiverse Settings

Echo Valleys

Landscapes that replay historical events as visible but intangible echoes. Observers can witness past battles, conversations, or daily life, making these areas valuable for historians but potentially traumatic for visitors.

Haunted Fantasy, Historical Fantasy

Environments where geography, creatures, and civilizations have evolved in complex interdependence

Turtle Cities

Entire civilizations built on the backs of massive, ancient sea turtles that migrate between feeding grounds. City layout must account for the turtle's movement, and the creature's health directly affects the inhabitants' survival.

Nomadic Fantasy, Ocean Fantasy

Fungal Networks

Vast underground mycelial networks that connect distant locations, allowing rapid communication and travel. The fungal consciousness may demand payment for passage or have its own agenda that affects surface politics.

Underground Fantasy, Bio-Fantasy

Storm-Following Oases

Mobile green zones that travel in the wake of great storms, supported by storm-spirits or wind elementals. Desert cultures must track these moving oases for survival, creating nomadic societies with storm-prediction expertise.

Desert Fantasy, Nomadic Cultures

Coral Metropolises

Living coral reefs cultivated into underwater cities where the coral itself serves as buildings that grow, adapt, and respond to inhabitants' needs. The reef's health reflects the moral state of its inhabitants.

Underwater Fantasy, Bio-Architecture

How to Use These Ideas

Start by selecting geographical features that directly support your story's central conflicts and themes. Consider how each landscape creates specific challenges for your characters and opportunities for plot development. Layer multiple geographical elements to create complex, interconnected environments—for example, combine Ley Line Convergences with Crystal Cavern Networks to create underground magical cities. Always ask how the geography shapes daily life, trade, warfare, and cultural development rather than treating it as mere scenery.

Try Combining These

  • Combine Tidal Forests with Coral Metropolises for an amphibious civilization that lives both above and below the waterline
  • Layer Gravity Wells with Phoenix Nesting Grounds to create floating volcanic islands where phoenixes nest in zero-gravity environments
  • Merge Echo Valleys with Time Erosion Zones to create temporal battlefields where past conflicts influence present-day geography
  • Blend Fungal Networks with Dream Bleed Zones for underground realms where the mycelial consciousness shapes reality through collective dreaming
  • Connect Mana Springs with Season Borders to create magical oases that change elemental properties based on which seasonal realm currently influences them

Remember that the most compelling fantasy geography serves the story first and the map second. The best landscapes become characters in their own right, actively participating in your narrative rather than simply hosting it.
