The World tab sets the rules of your setting for the whole book — its genre, technology and magic levels, social order, how violent and how just the world is, and free-text descriptions that ground the writing. It’s the second of the four Book Settings tabs. Think of it as the book-wide “World Rules”: a ruleset every scene is written against, separate from the individual World entities you build in the World step.
Book Settings → World: the book-wide world ruleset, with free-text detail under “Advanced”.
What’s on this page
The world dials: genre, technology, magic (and magic-system type), social structure, violence, morality, and world justice.
An “Advanced settings” drawer of free-text fields: world description, tone, era, social description, physics, magic rules, morality, and dominant values.
Two fields appear only when Magic isn’t “none” — the magic-system type and the magic rules.
How to use it
1Set the dials first — they define the world in one line each and pre-fill sensible defaults from your genre.
2Open Advanced to add the prose that makes the world specific: its era, physics, social texture and values.
3Keep the World genre consistent with the Book tab’s genre — a mismatch raises a validation warning.
Storyum has two things called “world”, and they do different jobs. This World tab sets the book-wide World Rules — one ruleset for the whole book: its genre, tech and magic levels, social order, and the free-text detail that grounds it. The World block in the World step is different: those are individual world entities you can create several of and attach to scenes. The tab here is the backdrop every scene is written against; the entities are specific places in it.
How these reach the book. The World tab’s settings are validated as a ruleset and folded into the scene context the pipeline builds — so they shape what the world can and can’t contain in every chapter. The dials set the hard limits (tech, magic, violence); the free-text fields add the texture.
The World tab, field by field
The dials sit up top; the free-text detail is under “Advanced settings”. Two fields — the magic-system type and the magic rules — appear only when Magic isn’t set to “none”.
The world dials
Each defines the world in one choice. Picking a Book-tab genre pre-fills matching defaults here.
