s4h-writing-worldbuilding

Audits a fictional world for internal consistency, texture, economy, and constraint-story alignment. Use when a world feels thin, generic, like a backdrop rather than a place people actually inhabit. Triggers: 'the world feels thin', 'worldbuilding', 'my world doesn't feel real', 'the setting is generic', 'world audit', 'the world feels like a backdrop'.

# Writing: Worldbuilding

Worlds fail when they are described rather than inhabited. The difference is texture. A described world tells you what things are — "a dystopian future where technology controls society." An inhabited world shows you what it costs to live there: what people eat, what they fear, what they fight over, what they take for granted, what they lie about. The first is a category. The second is a place.

The test of a well-built world is not comprehensiveness — it's necessity. Does the world create the story's conflict, or is it merely a backdrop? In a well-integrated world, the story's central problem could only happen in this world, in this configuration. The colony's resource scarcity creates the political structure that creates the protagonist's impossible choice. Remove the world, and the story doesn't exist. In a backdrop world, you could set the same story in contemporary New York without changing anything essential.

The second test: specificity of texture. The world must feel inhabited not through encyclopaedic exposition, but through specific, surprising detail that implies a larger reality. One specific food item, one specific ritual, one specific slang term tells the reader more about the world than three pages of history. The detail does double duty — it characterises the world and implies the systems that produced it.

## Your Process

**Step 1: Rules**
Map the world's governing systems: physical, social, technological, magical, or political. What are the rules that cannot be broken? Are they internally consistent — does the magic system create loopholes the story conveniently exploits? Does the technology appear and disappear based on plot convenience? Rules only function as worldbuilding if they constrain the story.
