settings_ethernet

Grows with you

Brainstorm together

Invite anyone to review any pages you decide to share. Sometimes a second set of eyes makes all the difference.

Create buildings

Fill your towns with stores, offices, historical buildings, and residences for your characters.

Create conditions

Conditions affect your characters for better or for worse. Create diseases, blessings, and more.

Kingdoms, countries, regions: you decide what international borders look like in your story.

Create creatures

Your personal bestiary includes the wildlife, critters, merfolk, and other interesting beings of your world.

Create deities

Gods, goddesses, and other godly beings in your world — every world came from somewhere.

Create floras

Paint your landscape with rich flora like plants, flowers, trees, and other nature.

Create governments

The organizations of your world that keep it running smoothly — or not!

Create groups

Bundle your characters, locations, items, and other ideas into any kind of collection you need.

Create jobs

Jobs build words. How do your characters make a living? What skills are the most in-demand?

Create landmarks

From the smallest statue to the biggest mountain, landmarks can play important roles, too.

Create languages

Language is a bond that weaves a culture together. Are there any new languages in your world?

Create magic

A source of magic often creates a multitude of spells, potions, and occasional trinkets.

Create planets

Celestial bodies orbiting through space, carrying a planet's-worth of worldbuilding opportunities.

Create your gadgets, gizmos, and all kinds of advanced (or primitive) technologies.

Create towns

Towns can both unite and divide your characters. Keep track of what makes your towns unique.

Create traditions

Everyone has something they celebrate. Honor your characters by detailing their traditions.

Create vehicles

Vehicles come in many shapes and sizes: cars, boats, spaceships — or something completely new.

Create sports

People are naturally competitive, and sports seem to naturally emerge in almost every world.

Create foods

People of all kinds eat and drink things of all kinds. Come eat, drink, and be merry!

Create schools

From Hogwarts to Walkerville to Brakebills, schools educate every new generation in our worlds.

"Really clever and beautifully organized way for storytellers to create a world."

— Alec P.
