Kralizec
the Typhoon Struggle
Kralizec, also called the Typhoon Struggle, was the long foretold battle at the end of the universe. The God Emperor Leto Atreides II used the term for the chaotic age of Famine and Scattering that followed his death, and it later named the final war against the Thinking Machines.
Kralizec, also called the Typhoon Struggle, is the long foretold battle at the end of the universe. Frank Herbert introduces the word in Children of Dune. In Brian Herbert and Kevin J. Anderson's sequels it becomes the name of the final war against the reborn Thinking Machine Empire. (Children of Dune; Expanded books: Hunters of Dune; Sandworms of Dune)
The Typhoon Struggle#
In Children of Dune, Kralizec is the Typhoon Struggle, the battle at the end of the universe. It is the same book in which Leto II commits himself to the Golden Path. (Children of Dune)
Leto's tyranny in God Emperor of Dune is meant to pen humanity up so that, after his death, it bursts outward and can never again be caught at a single point of failure. That outburst is the Famine Times and the Scattering of Heretics of Dune. Readers often call this Leto's Kralizec, but Frank Herbert's novels don't put the word to it. (God Emperor of Dune; Heretics of Dune)
The Day of Kralizec#
In Brian Herbert and Kevin J. Anderson's sequels to Chapterhouse: Dune, Kralizec takes on a firm meaning: the final reckoning with the reborn Thinking Machine Empire of Omnius and Erasmus. The plots of the end of the age are laid in preparation for it, including the machines' hunt for an ultimate Kwisatz Haderach, believed to be the fulcrum that would tilt the battle toward whoever held him. (Expanded books: Hunters of Dune; Sandworms of Dune)
The Day of Kralizec is the great battle in which ragged human fleets meet the machine fleet above Chapterhouse and Junction, while on the machine homeworld of Synchrony the last confrontation of human, machine and Face Dancer plays out. It closes the Dune timeline. (Expanded books: Sandworms of Dune)

Followed from this entry

Golden Path
The Golden Path was an expansive prescient interpretation, visible only to the Kwisatz Haderach and the Bene Gesserit, that revealed the single optimum route through the threads of cause and effect that would guarantee the long term survival of the human race.

The Scattering
The Scattering was the great dispersal of humanity into uncharted space that followed the death of the God Emperor Leto II. Driven by famine and the collapse of his empire, countless humans fled the Old Imperium forever, fulfilling the design of the Golden Path.

Kwisatz Haderach
The Kwisatz Haderach was the prophesied culmination of the Bene Gesserit breeding program, a male able to access the genetic memory of both his male and female ancestors and to bridge space and time through prescience. Paul Atreides and his son Leto II became the beings the Sisterhood had sought.

A dated chronology of the Dune universe, from the first age of space travel and the Butlerian Jihad to Paul Atreides, the God Emperor, the Scattering and the last war with the machines. Events run oldest first, era by era, and every entry says which book it comes from.

Chapterhouse
Chapterhouse was the Bene Gesserit term for the planet that served as the Sisterhood's home base. In its final form it was a hidden, deliberately unsettled world shielded from prescient eyes and, in the end, remade into desert to shelter the last sandworm.

Erasmus
Erasmus was an independent and eccentric robot who served the evermind Omnius while pursuing his own study of humanity. His murder of Serena Butler's infant son helped ignite the Butlerian Jihad, and millennia later his manipulations shaped the final battle of Kralizec.

Edrik: the Steersman of Kralizec
Edrik was a Spacing Guild Navigator, one of the line called the Edrics, who rose to lead his fellow Steersmen as the prophesied time of Kralizec approached. His efforts to secure spice and a synthetic source of melange ended when he was killed by the Enhanced Face Dancer Khrone.
Emperor's Blade: the Corrino dagger that shadowed Muad'Dib
The Emperor's Blade was a jewel hilted dagger handed down from Emperor to Emperor of House Corrino. Given to Duke Leto Atreides and returned, offered to Feyd Rautha for his death duel with Paul Atreides, and driven into Muad'Dib by Count Fenring, it ended its known history enshrined on Caladan, where the blood preserved on its edge yielded the clone Paolo.
Enhanced Face Dancer
Enhanced Face Dancers were a refined breed of Tleilaxu shape changer first released into deep space by Hidar Fen Ajidica and later improved by the Thinking Machines. Undetectable even by the Bene Gesserit, they served Omnius and Erasmus while secretly pursuing their own ascendancy, until Erasmus destroyed them all with a hidden kill switch.

Heighliner: the great foldspace carrier of the Spacing Guild
The Heighliner was the immense starship of the Spacing Guild, a vessel large enough to hold whole fleets of smaller craft and many thousands of passengers. Piloted by melange saturated Navigators, it folded space to cross the universe in an instant, and the Guild's monopoly over it made the Heighliner the quiet arbiter of Imperial power.
Hidar Fen Ajidica
Master Researcher Hidar Fen Ajidica was a Bene Tleilax scientist who led Project Amal on the captured world of Ix for twenty years, seeking an artificial spice. He schemed to break from the Imperium with his own army and Face Dancers before dying during the Great Spice War.

Janess Idaho

Khrone
Khrone was the true leader of the Tleilaxu Enhanced Face Dancers, a secret Myriad that posed as servants of the reborn thinking machines while plotting to inherit the universe once humanity and the machines had destroyed one another.
