Q 01Before it was published as a book in 1965, Dune appeared as two serials in which magazine?
Analog
Analog ran Dune as two serials between December 1963 and May 1965, but the sequel went to a rival: Dune Messiah was serialized in Galaxy in 1969.
Q 02What are the sandstorms of Arrakis called, with winds that can reach 700 kilometres per hour?
Coriolis storms
Coriolis storms draw their force from the planet's own rotation, which amplifies winds across the open flatlands; Paul times his final attack for one because it shorts out his enemies' shields.
Q 03What title is given to the Guild Navigators who pilot ships through folded space?
Steersmen
Steersmen is the Guild title: Edric in Dune Messiah is a Guild Steersman, a Navigator so saturated with melange that he floats in a tank of spice gas and foresees safe paths through folded space.
Q 04By what name do the Fremen reverently refer to the giant sandworms of Arrakis?
Shai-Hulud
Shai-Hulud, the 'Old Man of the Desert', is sacred to the Fremen, yet they ride the worms: maker hooks pry open a scale so the worm rolls it skyward and will not dive.
Q 05What is the dangerous test a Bene Gesserit Reverend Mother uses to determine a subject's humanity called?
Gom Jabbar
Gom Jabbar is the poison needle held at the neck while the hand burns in a box of pain: pull away, as a trapped animal would, and the needle strikes.
Q 06In the Bene Gesserit litany recited throughout the Dune novels, what is 'the mind-killer'?
Fear
Fear is the mind-killer, 'the little-death that brings total obliteration'; the Bene Gesserit recite the litany to steady themselves in danger, letting the fear pass over and through them.
Q 07Which planet serves as the ancestral homeworld of the ruthless House Harkonnen?
Giedi Prime
Giedi Prime is a dark industrial world with little photosynthesis left; by the later novels the Harkonnens are gone and the planet has been renamed Gammu.
Q 08In Dune, which brutally efficient military force secures the Padishah Emperor's power?
Sardaukar
The Sardaukar's reputation as unstoppable ends in Dune, when Paul's Fremen army defeats them and the Emperor is deposed.
Q 09With thinking machines outlawed, which trained humans do the computing for noble houses?
Mentats
Mentats are trained as 'human computers'; many sip sapho juice, which they say sharpens the mind and which stains their lips ruby red.
Q 10Which actress plays Paul's mother, Lady Jessica, in Denis Villeneuve's Dune films?
Rebecca Ferguson
Rebecca Ferguson plays Lady Jessica, a role Villeneuve enlarged: the studio synopsis calls her a 'warrior priestess', which he joked was better than 'space nun'.
Q 11What name do the Bene Gesserit give the male superbeing their centuries of selective breeding are meant to produce?
Kwisatz Haderach
Kwisatz Haderach means 'the shortening of the way'; Paul fulfils the plan a generation early because his mother, ordered to bear a daughter, gave Duke Leto a son instead.
Q 12Which lush, oceanic planet is the ancestral home of House Atreides?
Caladan
Caladan had been the Atreides home for twenty-six generations when the Emperor ordered Duke Leto to Arrakis, a posting the Duke accepted knowing it was a trap.
Q 13What is the name of the Fremen leader who becomes Paul Atreides' mentor on Arrakis?
Stilgar
Stilgar leads the Fremen band that captures Paul and his mother; he spares them in exchange for training in their fighting technique and takes them into his tribe.
Q 21Heavy melange use can unlock what ability to glimpse possible futures?
Prescience
Prescience is the limited foresight melange can unlock; Guild Navigators depend on it to plot safe courses through folded space, and Paul's visions grow once he breathes spice-laden air on Arrakis.
Q 22What is the violent eruption on Arrakis that brings melange to the desert surface called?
Spice Blow
A spice blow begins when water seeps into a buried pre-spice mass; the fermenting mass builds up gas until it bursts through the dunes, throwing raw melange onto the surface.
Q 23What do the Fremen call the sacred weapon they grind from a sandworm's tooth?
Crysknife
Q 14What specialized garment conserves the body's moisture in the deserts of Arrakis?
Stillsuit
A stillsuit filters sweat, urine and even breath back into drinking water, sipped from a tube at the neck; a well-kept Fremen suit loses only a thimbleful of moisture a day.
Q 15In Dune, what do the Bene Gesserit call their trained power to control others with nothing but selected tone shadings of speech?
The Voice
The Voice is feared enough that Baron Harkonnen sets a deaf guard over Jessica, since a man who cannot hear her cannot be commanded.
Q 16What is the name of the musical instrument Gurney Halleck is known for playing?
Baliset
The baliset is a nine-stringed descendant of the zither that Gurney Halleck strums between battles; for the 1984 film the prop makers disguised a real instrument, the Chapman Stick.
Q 17In Dune, what is the sandworm's larval stage called, a small leathery creature that locks away water to keep Arrakis dry?
Sandtrout
Sandtrout wall water away because it is poison to the adult worm; in Children of Dune, Leto II lets them coat his skin and so begins his own change into a sandworm.
Q 18Which Fremen woman appears in Paul Atreides' dreams before he ever reaches Arrakis?
Chani
Chani becomes Paul's lifelong love, but to take the throne he marries the Emperor's daughter in name only, and Chani remains officially his concubine.
Q 19What are the enormous Guild starships called that carry other ships between star systems?
Heighliner
Heighliners are so vast that every frigate and transport House Atreides owns fits in one corner of a hold; unable to land, they park in orbit while smaller craft ferry cargo down.
Q 20In Dune, which Reverend Mother, the Emperor's Truthsayer and Lady Jessica's old teacher, tests Paul with a poisoned needle?
Gaius Helen Mohiam
Gaius Helen Mohiam taught Paul's mother at the Bene Gesserit school; intrigued by the boy's prophetic dreams, she comes in person to hold the poisoned needle at his neck.
Crysknife blades come 'fixed' or 'unfixed': an unfixed one must stay close to a human body's electrical field or it disintegrates, and none may be sheathed until it has drawn blood.
Q 24Which ancient upheaval led to the ban on thinking machines throughout the Imperium?
The Butlerian Jihad
The Butlerian Jihad left one commandment in the Orange Catholic Bible, 'Thou shalt not make a machine in the likeness of a human mind', and that ban still shapes the Imperium when Dune begins.
Q 25What do the Bene Gesserit call a Reverend Mother's inner access to the lives of her female ancestors?
Other Memory
Other Memory reaches only the female line; the Sisterhood's whole breeding programme exists to produce a male who can look where they cannot, into the male line too.
Q 26Who serves as Baron Vladimir Harkonnen's twisted Mentat?
Piter De Vries
Piter De Vries is credited with inventing residual poison, and dies beside Duke Leto when the captive Duke bites down on a poison-gas tooth meant for the Baron.
Q 27Who is the Imperial Planetologist of Arrakis when the Atreides arrive, secretly leading the Fremen plan to green the desert?
Liet-Kynes
Liet-Kynes inherited both the Imperial post and the Fremen's secret terraforming dream from his father, the planet's first planetologist; he dies stranded in the open desert.
Q 28What gave Gurney Halleck the scar along his jawline?
An inkvine whip
An inkvine whip, laid on by Glossu Rabban in a Harkonnen slave pit, left Gurney's scar; the vine's beet-coloured marks go on hurting for years.
Q 29What is the term for a small, winged aircraft used for reconnaissance and transport on Arrakis?
Ornithopter
Ornithopters fly by beating their wings like birds; Paul and his mother shake off Harkonnen pursuit by flying one into a storm they were not expected to survive.
Q 30What remote-controlled assassination device is sent to kill Paul soon after he arrives on Arrakis?
Hunter-seeker
A hunter-seeker is a sliver of floating metal steered by an operator hidden nearby; it kills by burrowing into the body, and Paul destroys the one sent for him.
