A PRACTICAL GUIDE

How to use the Worldbuilding Generator.

Build rules that affect ordinary life as well as major conflicts. Ask how geography, resources and institutions shape the characters' available choices.

Make the workflow fit your task.

Choose one physical or social constraint and trace its effects through food, travel, work and power. Record those consequences as rules characters must navigate rather than disconnected background facts.

Decisions and troubleshooting.

Where should worldbuilding stop before drafting?

Develop the rules that affect the next scenes and central conflict. Details can grow as the story reveals a practical need for them.

Why does the setting feel decorative?

Give a resource or institution a consequence for an ordinary choice. A water shortage becomes tangible through storage, trade and daily routines.

Try it with your own source.

Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
