World Maps

Procedural Generation

World maps start from a seed phrase. Enter any text in the seed field and Cartographer runs it through a deterministic random number generator to scatter terrain points across the canvas. Voronoi geometry converts those points into cells, and multi-octave noise assigns elevation to each cell.

The same seed always produces the same base map — useful for sharing your world configuration with players or regenerating if you want to start over.

Continent modes: Pangea (one large landmass), Continents (2–4 separated masses), or Shattered (many small islands). Adjust the sea level slider to shrink or expand the ocean. More sea level = more ocean = more islands.

Drawing Territories

Territories are the named, colored regions on your world map — kingdoms, factions, empires, or biomes. There are two ways to create them:

Freehand drawing: Select a territory, click Draw, and trace the border on the map. As you approach an existing territory border within 40 pixels, the cursor snaps to it. Close your polygon to finish. Works for any shape.

Zone-paint mode: On procedural maps, click individual Voronoi cells to assign them to a territory. Faster for assigning large regions without freehand drawing.

Each territory has a name, color, and optional faction/group label. All are editable at any time.

Elevation & Terrain

The elevation layer is generated at map creation and persists independently of your territories. The Generate tab shows an elevation preview. When you auto-stylize, the elevation data is passed to the style engine so it knows where to place mountains, forests, and lowlands — your prompt just sets the visual style.

Frequently Asked Questions

Can I change the seed after drawing territories?

Regenerating the seed resets the procedural base map but does not delete your drawn territories. Territory shapes are stored independently, so they'll persist over the new base — though they may no longer align with coastlines.

How many territories can a map have?

There is no hard limit. Maps with 50+ territories work well. Very large territory counts may slow down the auto-stylize step as more data is processed.

Can territories overlap?

Yes, but it's not recommended — the style engine will render overlapping regions as mixed colors. Use the border snap system to keep territories edge-to-edge without gaps or overlaps.
