# Worlds & long-form

> World Books, interactive stories and novel mode — the long-form side of Reverie.

Three things live in this section. **World Books** hold reusable lore that characters, stories and novels all draw on. **Story mode** plays an authored narrative — chapters, milestones, roles, data panels — where the AI writes every scene fresh. **Novel mode** is a blank page you direct one beat at a time.

Stories and novels are paid for in credits per generation, not by subscription, and both default to the same model. Neither is gated — both are available to everyone.

**[World Books](https://reverie.im/en/docs/writing/world-books)**

Reusable lore that surfaces by meaning. Attach a book to a character,
a story or a novel and the right entries reach the model on their own.

**[Story mode](https://reverie.im/en/docs/writing/story-mode)**

Pick a role, play through chapters, unlock milestones, keep several
saves of the same story running side by side.

**[Writing a story](https://reverie.im/en/docs/writing/writing-interactive-stories)**

The story editor's five tabs, every field and its limit, the AI
helpers, and what publishing does and does not get you.

**[Novel mode](https://reverie.im/en/docs/writing/novel-mode)**

A three-step wizard, then one directive at a time. Illustrations,
covers, sharing, Markdown and HTML export.

**[Directing prose](https://reverie.im/en/docs/writing/directing-prose)**

What **Do**, **Say**, **Story** and **Look** each mean to the
model, and how to get a scene worth reading out of one line.

**[Writing styles](https://reverie.im/en/docs/writing/writing-styles)**

Presets, styles extracted from a description or a pasted sample, a
live preview on your own cast, and a shareable library.

**[Chat to novel](https://reverie.im/en/docs/writing/chat-to-novel)**

Adapt a whole conversation into prose as a background job. Three
adaptation modes, a credit estimate before you commit.
