The World of Robert Jordan's The Wheel of Time is an encyclopedia for the bestselling The Wheel of Time epic fantasy series of novels by Robert Jordan about the unnamed world where the plot takes place, which is often referred by fans of the series as the World of the Wheel. It is published in the United States by Tor Books and in the United Kingdom by Orbit Books. The bulk of the text was written by Teresa Patterson based on notes and information provided by Jordan, who also serves as overall editor on the project. While the information in the guide is broadly canonical, the book is deliberately written with vague, biased, or even downright false (or guessed) information in places, as Patterson felt this would reflect a key theme of the series (the mutability of knowledge across time and distance).
