How a Fantasy City Generator Helps You Build Worlds Fast
A city generator makes layout choices for you. It sets roads, blocks, rivers, walls, and districts. You get generated maps you can print, share, or tweak. Your focus shifts to story, culture, and play.
⏳Old way: draw by hand for hours. Or skim random town tables with no visual.
⏰New way: click, get a readable fantasy city, export, and start writing scenes.
Pair that map with worldbuilding tools for lore, NPCs, and events. Now your city feels alive.
Top City-Building Mistakes and How to Fix Them
Mistake 1: Too much detail at the start
👉🏻Fix: block your city first. Add only key points of interest (gate, market, temple, docks). Fill in more when play needs it.
Mistake 2: No scale or legend
👉🏻Fix: pick a unit right away. Use the tool’s scale bar if offered. Add a short legend for districts and landmarks.
Mistake 3: Empty streets
👉🏻Fix: attach simple NPC notes to each district. Two lines per shop. One hook per square. Keep it light.
Mistake 4: Map and lore live in different places
👉🏻Fix: keep “maps created,” notes, and art in one workspace. Use folders, pins, or collections so you can find things in seconds.
Mistake 5: No export plan
👉🏻Fix: check export formats before you commit to a tool. You’ll want PNG for quick sharing. SVG if you plan to edit lines in a vector app later.

Key Features to Look for in a Fantasy City Generator
- Export options: PNG is easy for VTTs and print. SVG is great if you edit roads and blocks later. Watabou supports both. Inkarnate supports exports and larger sizes on Pro. Know how your tool saves your generated maps.
- Pins and linking: If you want clickable points of interest, make sure the platform supports pins or labels that link to notes or pages. World Anvil does this out of the box.
- Online vs offlin:. Inkarnate is online only. Wonderdraft is offline with a one-time purchase. Pick based on your internet and team setup.
- Scope: Need a single city? Watabou or Worldographer can be fastest. Need the world around it first? Start in Azgaar, then go city-level.
Rights and plans: If you plan to sell content, check license and pricing. Inkarnate Pro includes commercial use rights per its terms. Wonderdraft is a one-time license. Read the fine print.
Step-by-Step: Use a Fantasy City Generator with Summon Worlds
Step 1: Make the base map
Open Watabou. Pick a seed you like. Export PNG or SVG. Or build a styled city in Inkarnate and export. Keep it simple. Your story will add the rest.
Step 2: Set your POIs
If you want interactive pins, upload the map to World Anvil and mark points of interest. Link each pin to short notes or encounters.
Step 3: Bring it into Summon Worlds
Create a collection called “Greyharbor City” (or your name). Add art and notes for districts, factions, and shops. Use AI Character Chat to roleplay with the innkeeper or captain. Use Voice Generation to give them a voice. Keep all your maps created, portraits, and hooks in one place.
Step 4: Add the wider world
Need borders, rivers, and trade routes? Use Azgaar to shape the region. Note travel times and terrain. Your city now fits a real map.
Step 5: Prep play
Attach one scene hook to each district. One rumor per tavern. One secret per guildhall. You’re done. When players wander, you have a response ready.
