How do you build a whole world?
Lord of the Rings, Disc World, Game of Thrones, Handmaid’s Tale — These fantasy series are as much about their world as they are about the characters and story. Done right, the world itself becomes reason enough to read the book. That is why world building is important and daunting.
Readers love their fantasy worlds, and if the writer is lucky, the world takes on a life of its own. Readers become fans. Then they become critics. If the author does get the world right, readers will tweet.
