I get this question a lot, and I can give you a short answer and a very long answer.

The Short Answer

The Cosmere is an interconnected universe that my epic fantasy stories take place in that share some characters. Think MCU, but for a bunch of epic fantasy worlds, there are crossover characters, but the focus is more on the different cultures mixing and things like this. So Star Wars, but fantasy, you could kind of imagine, except there's not really spaceships and things yet. There are some future books that have it.

If you visit my Books page, you can see a list of my books categorized by which take place in the Cosmere and which do not. And here’s a good rule of thumb that mostly works: if the book contains Earth in any shape or form, then the story is not set in the Cosmere. Also, my children’s books and The Wheel of Time are not part of the Cosmere.

So anyway: "What's the Cosmere?" The Cosmere is the name for this universe.

The Long Answer
