A generated island world rendered in 3D, with forests, snow-capped mountains and rivers running to the sea

From the first coastline to the last castle

I

Land that makes sense

Tectonic ridges, erosion, climate and rainfall decide where rivers run and which biomes grow. Coasts, deltas, glaciers and deserts land where they should.

II

Sculpt and paint by hand

Raise mountains, cut valleys or repaint a biome with brushes that work on the flat map and in the 3D view, with undo all the way back.

III

Walk the world in 3D

Forests, snow lines, rivers running into the sea, fog at the horizon. Orbit, fly with WASD, and drop down to see your coastline from the ground.

IV

Then fill it with people

Found towns and cities, draw kingdoms and nation states, mark ruins and lairs. Switch between the terrain and human layers at any time.

One map, any setting

The human layer comes with a list of things to place for each setting. Fantasy has hamlets to capitals, keeps to fortresses, temples, wizard towers and dragon lairs. Cyberpunk has megacities, arcologies, corporate territories and nation states. More settings are a list away.
