The Horus Heresy novel series is a collection of novels written by some of the Black Library's best-known authors. It chronicles the history of the devastating Horus Heresy, a galaxy-spanning civil war that lasted for seven years and ended with the death of the Emperor of Mankind and his internment upon the mighty prosthetic device known as the Golden Throne. This resulted in the death of enlightenment and the birth of the modern Age of the Imperium.
