Discrepancies between Dune novels

The collective Dune universe, as described by its creator Frank Herbert, or in works authorized by Herbert or his heirs, is comprised of the six original novels by Frank Herbert, the prequel novels by Brian Herbert and Kevin J. Anderson, and The Dune Encyclopedia by Dr. Willis E. McNelly. Despite their official and authorized nature, these works contain numerous discrepancies, both within particular works by the same author, and between the works by different authors.

In the specific case of The Dune Encyclopedia, it should be noted that, while Dr. McNelly was a close friend of Frank Herbert's, and his work written and published with Herbert's knowledge, permission and approval Herbert says he "hold[s his] own counsel some of the issues still to be explored" in the Chronicles.

In the discussions below, the term "rationalization" simply refers to explanations which are not explicitly found within any of the primary texts. 

Rationalization of Discrepancies Based on Literary Analysis

A Narrator shouldn't be conflated with the author of a literary work. Author Lois Leveen, Ph.D, explains the relationship between author and narrator in, The Narrator. Because our universe differs from that of the Duniverse there must exist a narrator from within that use universe. While Frank Herbert is the author of Dune, he is unlikely to be one of the narrators. The same is true of all texts in-universe, whether they are narrative or historical.

Though theories of different Duniverse narrators are outside of the scope of this article, potential narrators may include Irulan Corrino, Paul Atreides, Leto Atreides II, Duncan Idaho, Siona Atreides, the Oracle of Time, Daniel and Marty, and Erasmus.

In addition, all texts and source materials are likely to have been written in Galach and other languages in use within the Duniverse. It's clear due to stylistic differences, that at least two narrators exist, and due to the time span likely many more with differing historical accounts and source texts. Any discrepancies within texts are likely due to the combination of different source materials, different narrators, and different translators.

The existence of the writings of Irulan, Leto II, and the Dune Encylopedia—which is viewed as a heretical account of the timeline of the larger Duniverse—don't require a complete an accurate depiction of events. Over great periods of time, history will be written and rewritten, oral traditions will change. Language will evolve. History in the Duniverse will conflict, just as history on Earth does. 

Narrators often misunderstand, misquote, misremember, misinterpret, display certain biases, recount people, events, and dialogue differently, or intentionally alter narratives. Discrepancies by translators suffer similarly, with the compounding addition of inadequate translation of source texts.

Further rationalizations for discrepancies aren't strictly necessary, but this doesn't mean it can't be fun or illuminating to speculate.

Discrepancies Between the Original Novels

Alia's ancestral memories in Dune

Jessica endures the spice agony, and receives the memories of a Fremen Reverend Mother who had, in turn, received the memories of the Reverend Mother who came before her. As a result, Jessica inherits the memories of countless generations of Reverend Mothers. Jessica's unborn child, Alia, also inherits these memories and is born with the awareness and memories of an adult in the body of a child. In Children of Dune, however, Alia instead possesses the memories of her ancestors (including the Baron Harkonnen).

• Rationalization: Alia gives herself a massive spice-overdose in Dune Messiah. It is possible that this spice-overdose triggers her ancestral memories.
• Rationalization #2: It was also stated that Alia possessed her other memories all throughout her life from birth, but succumbed to them through a combination of flesh-weakness (puberty), the disapproval and subsequent burying of friendly other-selves (such as the other-memory version of the Lady Jessica), and futile attempts to dominate other-memories instead of forge a working relationship with them (as stated by Leto II).

The Bene Gesserit's ancestral memories

The Bene Gesserit Reverend Mothers in Heretics of Dune are possessed of ancestral memories. However, this ability is not possessed by any Bene Gesserit in the earlier novels. When Jessica endures the spice agony in Dune, for example, she gains access to the memories of all the Reverend Mothers who came before her, but she doesn't gain ancestral memories.

• Rationalization: The events of Heretics of Dune take place 1,500 years after God Emperor of Dune. During that time, the Bene Gesserit have all been explicitly bred to inherit the genes of Siona Atreides. Siona briefly gained ancestral memories as a result of enduring the spice agony. Siona's father, Moneo, also briefly gained ancestral memories as a result of enduring the spice agony. It seems likely that ancestral memories are a trait inherited from Ghanima, bred for by the God Emperor, and triggered by the spice agony. It is possible that the Bene Gesserit further strengthened this trait through their breeding program. Or it may be that the Bene Gesserit's endurance of the spice agony is simply more prolonged, intense, and/or prepared for than those endured by Siona and her father.

Duncan Idaho's Ghola Memories

In God Emperor of Dune, the Duncan Idaho ghola remembered dying while defending Paul and his mother Jessica. However, he also recalls events witnessed by his first reincarnation: "Idaho remembered a strange child - twins, really: Leto and Ghanima, Paul's children, the children of Chani, who had died delivering them." Later, while being interviewed by Leto II, Duncan states "I wish I had the memories of those others [his predecessors]" to which Leto replied "You couldn't have and still be the original."

• Rationalization: It is possible that as Idaho does not appear to remember dying during the events of Children of Dune, he could have been restored from pre-death cells of the original Idaho ghola.
• Rationalization #2: This could have been an early (and unknown to Leto) attempt by the Tleilaxu to incorporate serial ghola memories into one body. They had made a previous attempt to change the psyche (and body) of a ghola with disastrous results, so it would be understandable that they would be more cautious with any changes made.

In Heretics of Dune, Duncan Idaho is initially awakened with his memories only up to the point of his original death in Dune (before Paul Atreides becomes Muad'dib). However, he later speaks, prior to gaining the memories of his later incarnation, of being taught how to resist the Voice control of the Bene Gesserit: "I learned the way of that from Paul Muad'dib himself."

• Rationalization: It's possible that Paul taught Duncan how to resist the Voice before they came to Arrakis and that Duncan is simply referring to him as "Muad'dib," due to his earlier training and study of history. It's also possible, perhaps even likely, that this is deliberate foreshadowing that Duncan's memories include his later incarnations.

Farok's Arm in Dune Messiah

A minor character named Farok is initially described with a missing arm: "Scytale returned his gaze to the old man [Farok], noted the empty sleeve dangling from the left shoulder and the lack of a stillsuit." Only a few paragraphs later, however, Farok has mysteriously regained his arm: ""Thrice blessed," Farok said, folding his hands into his lap in the ritual clasp."

• Rationalization: Simple writing error by Frank Herbert.
• Rationalization #2: Farok merely had a very short hand, hence the empty sleeve.
• Rationalization #3: Farok is secretly a Face Dancer.
• Rationalization #4: Farok is given back his hand very quickly “off-screen”.
• Rationalization #5: There are two Faroks.
• Rationalization #6: Farok had three hands, but one was cut off so now he has two, but there is still a stump.

Honored Matre's use of voice/Murbella's learning of it

In Heretics of Dune, an Honored Matre uses voice to good effect, but in Chapterhouse: Dune, Murbella sees it as one element of the cornucopia of Bene Gesserit skills which she looks forward to learning.

• Rationalization: It may be that only certain orders of Honored Matres learn voice, or that it was not taught until later in training, Murbella being but newly robed as an Honored Matre at the end of Heretics.

Scytale

Scytale is a Face Dancer. In Heretics of Dune, Scytale is a Tleilaxu Master. Heretics of Dune also establishes that Face Dancers are the servants of the Masters, who are not Face Dancers themselves.

• Rationalization: The Scytale appearing in Heretics of Dune is not, in fact, a ghola-descendant of the Scytale in Dune Messiah - although this is unlikely, as Scytale the Master also met Paul. Also, Masters with serial lives, as they are known in Heretics and beyond, was a Tleilaxu political development that came after the discovery of how to make gholas remember past lives in Dune Messiah. It is possible that ghola-Scytale was a Face Dancer who later became a Master.

The color of Arrakeen mourning

In Dune, the color of mourning for the Arrakeen people is, multiple times, said to be green. For example, Chani wears a green sash after Liet-Kynes dies for that reason. However, in Children of Dune, it is stated that "Alia wore the yellow of Arrakeen mourning, the color of the burning sun from Fremen History."

• Rationalization: The color of Arrakeen mourning was, for whatever reason, changed after Paul’s ascension.

First person to dream of ecological changes on Dune

In Children of Dune, Liet-Kynes is described as the originator of the dream of open water and greenery on Dune among the Fremen. However, the Appendix of Dune makes it clear that this idea first came from Liet’s father, Pardo. The story of the Fremen sent to execute Pardo falling on his own knife instead is also changed to one of an “Umma-Protector” of Liet’s being ordered to commit suicide.

Origin of the preborn

In Dune, Alia is born already aware and with the experiences of past Bene Gesserits because, while pregnant with her, Jessica drank the water of life in the ritual that made her a Reverend Mother. However, in Children, the creation of, so-called, “preborn” is ascribed to birth while the pregnant mother is already “addicted to spice” as Jessica and Chani (Leto and Ghanima’s mother) were. Of course, all inhabitants of Arrakis (and many others as well) are addicted to spice, and presumably their children are not preborn.

It is further suggested in Children that Alia’s “Abomination” nature as a preborn results from her having drunk the pure spice essence herself in an effort to bring on episodes of prescience. However, in the Dune, she was, of course, already exposed to the Water of Life before being born.

The nature of the Water of Life used during the Fremen orgy

In Dune, during the ritual of the Fremen orgy, a Reverend Mother converts a small amount of the Water of Life poison into a non-poisonous form that also acts as a catalyst to convert a large amount of the Water, which is then shared by the community. However, in Children the liquid used is described as being only a diluted form of the “pure” or “concentrated” spice essence used in by the Reverend Mothers (and by Paul to bring on intense bouts of prescience).

Discrepancies Between the Original Novels and Dune Encyclopedia

Note: As the Encyclopedia is an in-universe document, all of the following discrepancies could potentially be explained as mistakes made by the in-universe authors in compiling it. Any rationalisations offered, however, should not simply state 'A mistake by the in-universes author' or something similar. It should try to either go more in depth about how this particular error could be made or offer an alternate rationalisation.

The Date of Leto II's Death

In God Emperor of Dune, it is stated to be 3,508 years since Leto became Emperor in Children of Dune. However, the Encyclopedia places Children at 10,219 (the date which the references made in the original books match with) but God Emperor at 13,724 rather than 13,728, so it would be 3,504 years into his reign according to the Encyclopedia.

"Famine Times" v "Starvation"

God Emperor of Dune, Heretics of Dune and Chapterhouse: Dune consistently refer to the period after the death of the God Emperor Leto II which led to the Scattering as the "Famine Times", and no other name. However, the Encyclopedia always calls it "the Starvation".

• Rationalization: There were multiple names used to refer to this period, and "the Starvation" was used later on (as the Encyclopedia was published 300 years after Heretics and Chapterhouse).
  • Discrepancy to Rationalization: Considering that the Encyclopedia consistently refers to the Scattering as the Scattering, it is strange that they would have an alternative name for the Famine Times.

Duncan Idaho gholas

The Encyclopedia says that the Duncan Idaho ghola which appears in God Emperor of Dune ("Duncan-13724") was the last. However, in the original saga, twelve more gholas are created after, the last at the time Heretics of Dune, for the purposes of the Bene Gesserit, who are one of the main sources for the Encyclopedia.

Bene Gesserit origins

In the very first chapter of Dune, Reverend Mother Gaius Helen Mohiam says to Paul that the Bene Gesserit formed after the Butlerian Jihad (referred to as the "Great Revolt" here):

• "The Great Revolt took away a crutch. It forced human minds to develop. Schools were started to train human talents. We have two chief survivors of those ancient schools: the Bene Gesserit and the Spacing Guild."

This is repeated in "Terminology of the Imperium":

• BENE GESSERIT: the ancient school of mental and physical training established primarily for female students after the Butlerian Jihad destroyed the so-called "thinking machines" and robots.

This is directly contradicted in the Encyclopedia, which has the Bene Gesserit existing before the Jihad even began.

• Rationalisation: The Sisterhood did gain its modern power and shape according the Jihad in the Encyclopedia, however. After ten whole millenia, the misconception could easily spring up that it had only been begun after it.

Dar es-Balat (The Rakis Hoard) and Hadi Benotto

In God Emperor of Dune, we learn about the findings by archeologist Hadi Benotto at Dar es-Balat of Leto II's journals and various other writings. In the Encyclopedia, the findings are collectively called the Rakis Hoard, and are said to have been found in the year 15525 AG. In addition, Hadi Benotto is the fictional editor of the Encyclopedia, published in 15540 AG. However, in Heretics of Dune, set in the year 15229 AG, the writings at Dar es-Balat, which are not once referred to as the Rakis Hoard, were found centuries ago, and Hadi Benotto is long dead.

BC/AD and BG/AG calendars

Appendix II of Dune contains this quote: “Mankind's movement through deep space placed a unique stamp on religion during the one hundred and ten centuries that preceded the Butlerian Jihad.” The Jihad took place from 201 to 108 BG. So, in the timeline of the original dune series, space travel should have began circa 11,200 BG.

The first interplanetary space probe was Pioneer 5 which was launched in 1960. If we start at 1960 A.D. and add 11,200 years we get 13,160 AD - so this year corresponds to 1 AG in the original books. This is seemingly contradicted in the timeline of the Encyclopedia, which places World War II in 14,225 B.G. and thus places 1 AG in 16,170 AD - three thousand years after its placement in Dune.

• Rationalisation: The term 'deep space' did not have to refer to the solar system in 1965. Frank Herbert could easily have been referring to a different level of expansion.

Giedi Prime / Gammu, Caladan / Dan

In Heretics of Dune (Strd. 15229) Giedi Prime has been renamed Gammu, and Caladan has been renamed Dan. However, in the Encylopedia (published in-universe Strd. 15540) both planets are consistently referred to in the present tense as Giedi Prime and Caladan, and no renaming is even mentioned.

• Rationalisation: In the 300 years between Chapterhouse: Dune and the publication of the Encyclopedia, the planets reverted back to their original names. After all, we see Darwi Odrade call the planet Caladan in Chapterhouse, so it could even have been renamed between Heretics and that book - although Miles Teg does mention his histories call it Dan, those would have been published before the renaming.

Birthplace of Duncan Idaho

In Heretics of Dune, Duncan Idaho is specifically stated multiple times to have been born and raised on Giedi Prime under the Harkonnens. The Encyclopedia, however, claims that Duncan was born on Caladan and that was where he spent most of his early years.

Mother of Chani

According to Leto II (who has the memories of all of his ancestors) in God Emperor of Dune, Liet Kynes had Leto’s mother Chani with the noted Fremen herbalist Faroula. However, the Encyclopedia claims that Chani’s mother was named Flare and that she was merely a Fremen of no real importance with whom Kynes was raised in Sietch Tabr.

• Rationalisation: We see one example of Fremen giving multiple names to one person in Paul's 'sietch name' as Usul rather than Muad'Dib. This could also have been the case with Chani's mother - Faroula being her sietch name (as that was in Leto II's other memory) and Flare being her public one.

Zensunni beginning - 1381 BG/AG

In the original Dune series, the Zensunni split away from the teachings of Maometh, the so-called “Third Muhammad”, circa 1381 B.G. The Encyclopedia contradicts this by having the schism occur in 1381 AG.

Origin of the sandworms

In Children of Dune, Leto II says that the sandtrout "was introduced here from some other place. This was a wet planet then. They proliferated beyond the capability of existing ecosystems to deal with them. Sandtrout encysted the available free water, made this a desert planet . . . and they did it to survive. In a planet sufficiently dry, they could move to their sandworm phase." The Encyclopedia seems to say that the sandworms were native to Arrakis in the entry "Arrakis, Oxygen Saga", discussing an "oxygen-depletion catastrophe" said to have occurred 49.7 million years ago which led to a "nearly complete extinction of life" along with the loss of all oceans within the next million years, where according to the fossil record "the only survivors were several species of worms" which burrowed in the ocean floors, giving them "time to adapt to the gradual evaporation of what remained of the original oceans", so that once "desertification was complete, Shai-Hulud had become perfectly adapted to an arid environment."

• Rationalisation: Leto II was presumably drawing on memories of his human ancestors, so he could have been remembering the beliefs of researchers on Arrakis who thought they had good evidence for the scenario he described, but whose theories were invalidated by later evidence supporting the scenario in the Encyclopedia. Alternately, if some alien intelligence brought the sandtrout 49.7 million years ago, one of Leto II's ancestors could have discovered evidence of this that was lost to the writers of the Encyclopedia, who falsely believed the oxygen catastrophe was a natural event (the entry says an impact or near-miss from a comet is 'the most probable answer'). Leto II's phrase "was introduced" also may not necessarily imply the sandtrout were introduced by intelligent beings, in which case this could be compatible with a "panspermia" scenario where spores or other reproductive cells were able to drift through space in a dormant state before growing into sandtrout upon arriving at Arrakis.

Discrepancies Between the Original Novels and Prequels

Discrepancies between the original novels by Frank Herbert and the prequels written by Kevin J. Anderson and Brian Herbert are frequently used by critics of the prequels. Criticism of the prequels also extends to a perception of poor quality and a negation or misrepresentation of Frank Herbert's original points and themes. For example, John C. Snider wrote in his review of Dune: House Harkonnen:

"If any criticism could be made about the prequels, it's that they just don't have the Byzantine mystique of Frank Herbert's original novels. The characters within the prequels would fit well within any of the old pulp dramas - driven by vengeance, driven by justice, driven by love - you get the picture. The Harkonnens, for example, are so ridiculously evil it stretches believability that they could control a thriving empire for millennia! Frank Herbert was a master at plunging you into strange, alien worlds of the far-flung future. The prequel novels, while satisfying, will just never attain the artistry of the original."

Such critique are, ultimately, matters of opinion and taste. The inconsistencies below are matters of fact within the Dune universe.

Bene Gesserit Psychic Powers

In the original Dune books, Frank Herbert presents the Bene Gesserit as a secretive sisterhood whose members train their bodies and minds through years of physical and mental conditioning to obtain powers and abilities that can easily be seen as magical to the uninitiated. It is arguably an important aspect of their place in the Dune universe, and thematically within the books that their powers are not supernatural and mystical, but based on a thorough understanding of their physical body and the body politic.

Frank Herbert's Bene Gesserit were consummate politicians who understood the use of body, mind, and spirit in pursuit of power. Still, they do have some powers which might be classed as supernatural within the context of the created Duniverse. In example, the "genetic memory," or remembering the direct experiences of an ancestor or individual with whom they have "shared," most commonly via a spice-trance.

In Dune: The Butlerian Jihad, Kevin J. Anderson and Brian Herbert endow their ancient predecessors, the Sorceresses of Rossak, with telepathic and telekinetic abilities. Later, in Dune: House Harkonnen, they give the now fully-formed Bene Gesserit the ability to hide in shadows, close to invisibility. In none of the six original books does any Bene Gesserit give any hint of knowing of any such abilities of invisibility or telekinesis - not even in situations where such abilities would be lifesaving. Telepathy is mentioned in Dune by Emperor Shaddam during the confrontation between Alia, Baron Harkonnen and Reverend Mother Mohiam. He uses the term TP when Mohiam says that Alia is in her mind, but his reaction is more indicative that it is a sought after but never found mystical ability.

In Dune: House Harkonnen, the Bene Gesserit are also apparently able to sense and wrest control telepathically of a no-ship being flown by the Beast Rabban. This seems in stark conflict with the characterization of a no-ship in the original Frank Herbert novels as explicitly undetectable, most particularly by those with extra-sensory perception.

• Rationalization #1: In the Legends of Dune trilogy, Telekinesis is explained as the willing gathering and releasing of large amounts of static electricity. The discharging process often lead to many of it’s practitioners dying. This technique was most likely so dangerous that the Bene Gesserit found the ability too destructive and harmful.

• Rationalization #2: It is imaginable, especially in the case of the telekinetic powers which were only used to kill cymeks and resulted in the Sorceress's death, that the Bene Gesserit in the original novels had these powers, but a situation never arose where they needed to use them. It is never explicitly stated that they do not have these powers, they are just not expressed in the writing, much like the existence of Face Dancers and gholas were not mentioned in the original Dune, and yet play a significant role in its sequels.

• Rationalization #3: It is mentioned in the prequels that the telekinetic powers were a result of various chemicals that were found on Rossak. It may be that within a generation or two after the Sisterhood left Rossak, they lost these powers.

• Rationalization #4: The no-ship described in the prequels is a prototype model designed by a Richesean scientist, who is murdered by Rabban after building the ship. The plans for the technology are temporarily re-discovered by his Richesean colleagues, but are permanently lost when the orbital lab is blown up by the Sardaukar. The no-ships in the original novels are an independently-developed technology. So it is entirely possible that the original no-ship was only built to, basically, have a Star Trek-like cloaking device, while the no-ships from the original novels also included a prescience-shield.

"This will be your first time off-planet" - Paul's Early Years

In Dune, shortly before the move to Arrakis, Paul asks his father, "Are the Guild ships really big?" Duke Leto then replies, "This will be your first time off-planet," before explaining some of the intricacies of Guild travel. Leto's statement, coupled with Paul's lack of knowledge and general uncertainty, make it clear that Paul has never been offworld before.

In addition, Paul reflects that, "This world of Castle Caladan, without play or companions his own age, perhaps did not deserve sadness in farewell." This, coupled with other information, paints a fairly-vivid picture of Paul's life as the only child of a Landsraad Noble.

However, in Paul of Dune, in the year 10,187 AG, Paul travels to both Ecaz and Grumman. In the second Heroes of Dune novel, The Winds of Dune, in 10,188 AG, Paul joins a travelling Jongleur troupe with his friend Bronso Vernius (also aged 12 at the time), which takes him to Chusuk and Balut.

• Rationalization: Dune paints a picture about the three critical years 10,191 AG to 10,193 AG of the Imperium and the life of Paul Atreides. Kevin J. Anderson explained that Paul of Dune "is about the inaccuracies and liberties taken in Irulan’s purported histories of Muad’Dib." The following is an excerpt from Paul of Dune:

  One morning she [Irulan] went to Paul's Imperial office to talk with him, holding a copy of the first volume in The Life of Muad'Dib. She dropped the deep blue book on his desktop, a plane of polished Elaccan bloodwood. "Exactly how much is missing from this story? I've been talking with Bludd. In your accounts of your life, you left out vital details."
  He raised his eyebrows. "Your publication has defined my life's story."
  "You told me you had never left Caladan before your House moved to Arrakis. Whole parts of your youth have been left out."
  "Painful parts." He frowned at her. "But, more importantly, irrelevant parts. We've streamlined the story for mass consumption..."

Other Discrepancies

• In Dune, it is established, in the very first paragraph of the novel, that Paul was born on Caladan: "Do not be deceived by the fact that he [Paul] was born on Caladan and lived his first fifteen years there." This is verified further into the novel, and also in Dune Messiah. In Dune: House Corrino, Paul is born on Kaitain.
  • Rationalization: A rationalisation can be found in Hunters of Dune: "According to the legends, Paul Muad'Dib was born on Caladan, not Kaitain." "Legends are just that, sometimes fraught wtih errors, sometimes distorted intentionally. As an infant, Paul Atreides was christened on Caladan, and he considered that planet his home, until his arrival on Dune. You Bene Gesserits wrote that history."

• In Dune, Duke Leto sends agents to buy Jessica: "Not since the day when the Duke's buyers had taken her [Jessica] from the school had she felt this frightened and unsure of herself." In House Harkonnen, the Bene Gesserit send Jessica to Duke Leto without his consent, and he allows her to stay.

• In Dune: House Harkonnen, Liet Kynes meets up with the rogue elements of House Vernius, who have also enlisted the services of one Gurney Halleck. During this period, the two become close comrades, with a strong component of mutual respect. In the original Dune novel, however, Kynes' meeting with Halleck makes no reference whatsoever to this past contact - in fact, Halleck's manner is brusque and formal, whilst Kynes is notably resentful of Halleck's presence.
  • Rationalization: This was answered on the official Dune website: "More than fifteen years have passed. Gurney met Liet then on a different planet, when he was using a false name, and his appearance was different. It¹s not surprising he would not recognize Dr. Kynes."

• In Dune: House Atreides,it is general knowledge that the Tleilaxu are religious fanatics; however, in Heretics of Dune,this fact is a major revelation for the Bene Gesserit. The same is true when the nature of the Axlotl tanks are revealed in House Corrino.
  • Rationalization: The knowledge was slowly forgotten over the years, or during the Scattering and Famine Times.

• Fixing a crysknife is explained as "keyed to the body of the owner so it would dissolve upon his death" in this book. In Dune, "Fixed knives are treated for storage," which is demonstrably the opposite.

• In Dune, the Baron is shown to be a "seeker of sensations." Moneo Atreides, in God Emperor of Dune, explains it well, "The fat was a side-effect, then perhaps something to experience for itself, because it offended people and he enjoyed offending." However, in House Atreides, his weight is revealed to be the result of a disease given to him by Reverend Mother Gaius Helen Mohiam when he raped her. This also does not explain why Alia begins to put on weight in Children of Dune.
  • Rationalization: Moneo cannot have not have first-hand experience of the Baron, and could easily be mistaken about him.

• In Dune, Gurney Halleck explains that Duke Leto was "the man who rescued me from a Harkonnen slave pit, gave me freedom, life, and honor." In House Harkonnen, he escapes all by himself.
  • Rationalisation #1: It is somewhat implied by Paul of Dune that the original Dune novel may have been The Life of Muad'Dib, Volume 1, by the Princess Irulan. If this were so, Irulan would of course make mistakes, changes and simplifications, and this could easily be one of them.
  • Rationalisation #2: Gurney misremembered after a good 20 years.

• In House Corrino, Dr. Wellington Yueh explains how, following an industrial accident, he found a specialist to replace "Wanna's hips, spleen, and uterus with synthetic parts, but she could never have children." But in Dune, he wonders why Wanna Marcus never gave him children - he knows, as a doctor, "there was no physical reason against it."
  • Prequel Rationalization: This was answered on the official Dune website: "Yueh later learns that Wandra's injury did not, in fact, make her incapable of bearing children - but the Sisterhood had commanded her not to conceive."

• In Paul of Dune, when planning the "Great Surrender" ceremony, Paul orders all representatives to come to Arrakis with his frigate's cargo hold filled with water as a gift. From Dune: "Many, not understanding the prohibitive mass-ratio problem, may even think we'll bring water from some other planet rich in it."
  • Rationalisation: This could be intended as a humiliatingly expensive act of submission to Paul precisely because of how inefficient it is.

Discrepancies Between the Prequels

• The timeframe between these novels is in the vicinity of ten years, and no attempt is made to explain Ecaz's change of leaders, or their apparent about-face on all matters relating to House Atreides over this period.
  • Rationalization: In Paul of Dune, it is explained that Duke Prad Vidal is a sub-leader who oversees House Ecaz's holdings on Vidal's continent only. The Archduke Armand Ecaz oversees all of House Ecaz's vast holdings, which span various star-systems.

• In Hunters of Dune, it is revealed that Hasimir Fenring once stabbed Paul in the back. However, in Paul of Dune, he stabs Paul in the chest.
  • Rationalization: The truth was altered and distorted over 5,000 years. It is no surprise that the details are not quite right.
• In the timeline at the end of Hunters of Dune, the Orange Catholic Bible is said to have been compiled in the first century A.G. However, in Sisterhood of Dune, which is set in 5 B.G., it was compiled twenty years ago (25 B.G.)
  • Rationalization: the A.G. calender is possibly not exact, and the exact date of 1 AG could ocasionally vary, due to the Spacing Guild-like organizations and predecessors before 1 AG.
• In House Atreides, Aurelius Venport is named as the founder of the Spacing Guild. However, in the Legends of Dune and Great Schools of Dune trilogies, the Guild is formed 164 years after Aurelius’s death by the Corrinos after the defeat of Venport Holdings.
  • Rationalization: Aurelius founded VenKee Enterprises, which became Venport Holdings, a subsidiary of which was Foldpace Shipping Company, which became the Spacing Guild after the Corrinos defeated VenHold. In The Battle of Corrin, Norma also explains that Venport's figure will be expanded and warped over time into someone more important than he actually was as myth blurs with history.
• In House Harkonnen, it is stated that Jool Noret was killed by a tidal wave in his sleep. However, in The Machine Crusade, he dies awake, thinking that he has finally met an enemy he cannot fight.
  • Rationalization: Across time (over 10 millenia), the story was distorted.
• According to Dune, Terminology of the Imperium, the Battle of Corrin was "the battle fought near Sigma Draconis in the year 88 B.G." In The Butlerian Jihad: "he and his fellow Titans reached Corrin after an interstellar voyage of nearly two months. ... The cymek moved out onto the paved boulevards under the enormous baleful eye of the red giant." However, Sigma Draconis is not a red giant, it is an orange dwarf. It is unlikely that this star will become a red giant in time for the Butlerian Jihad.
  • Rationalisation: Despite it being unlikely, it did happen.
• An internal discrepancy in House Atreides, where it is stated in Shaddam's first chapter by Fenring that Elrood has reigned for 155 years as Padishah Emperor. The announcement of his death on Caladan, more than two years later, states that he died in the 138th year of his reign.
