The Chaoswar Saga is the final[1] trilogy in the Riftwar Cycle series of fantasy novels by Raymond E. Feist.

In the fantasy novels of Feist, a "riftwar" is a war between two worlds that are connected by some sort of dimensionless gap (rift).

The book was released in the United Kingdom on 30 January 2012 and in Australia on 1 February 2012.

First editions in all three countries have a continuity error in the later parts of the book.

Pug, a pivotal character in all of Feist's Riftwar novels, appears in two places at once due to an editing error.
