What makes a ghola the same person, and what are Face Dancers?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

The Bene Tleilax grew gholas from the cells of the dead and Face Dancers from the same tanks, then found a way to force a ghola's original memories back to the surface. Whether the man who wakes up is the man who died is a question the novels keep asking and never close.

  • Canon defines a ghola as an artificially created human replicated from a dead individual, grown in an axlotl tank and reconstructible from as little as one cell of the original being, and made almost exclusively by the Bene Tleilax. The tank is the vessel by which the Bene Tleilax reproduced a living human being from the cells of a cadaver, and the same tanks were used to create Face Dancers.▰▰▰▱▱ likely3 points

    • A ghola was an artificially created human, who was replicated from a dead individual. Gholas were created in Axlotl tanks and could be reconstructed from as little as one cell from the original being. They were created almost exclusively by the Bene Tleilax, although at least one (based on Miles Teg) was created by the Bene Gesserit shortly before the Return of the Honored Matres.Ghola - Dune Wiki analysis
    • An Axlotl tank or Axolotl tank was the "tank" by which the Bene Tleilax reproduced a living human being from the cells of a cadaver, producing a type of clone called a ghola. These tanks were also used in the creation of genetically engineered assassins known as Face Dancers.Axlotl tank - Dune Wiki analysis

  • Canon establishes that original memories are restored through psychological trauma. Conditioned by the Tleilaxu to assassinate Muad'Dib but unable to reconcile that conditioning with an innate love for the Atreides, the ghola Hayt recovered the buried memories of Duncan Idaho up to and including his death at the hands of the Imperial Sardaukar. After that the same method was used deliberately: the ghola would be forced to experience some kind of psychological trauma to force the memories to the surface.▰▰▰▱▱ likely3 points

    • Hayt was conditioned by the Tleilaxu to assassinate Muad'Dib. However, because of Idaho's innate love for the Atreides, Hayt could not reconcile this feeling with his conditioning. The psychological trauma that ensued from this paradox caused his Idaho's memories to emerge. As a result, the theory was proven correct.Ghola - Dune Wiki analysis

  • Canon establishes that each Idaho ghola came back carrying conditioning planted by its producer. Each Idaho ghola was produced by the Bene Tleilax and always possessed some deep-seated conditioning that was intended to assist the Tleilaxu in their political and cultural endeavors, and the success of such conditioning was often poor or resulted in unforeseen consequences. Even after Miles Teg restored the memories of Duncan Idaho to the ghola, Duncan could feel that the Tleilaxu planted something else in his mind. Only once did they attempt to change the cellular nature and the psyche of the original Duncan, for which they paid dearly, and they dared not try such a thing again.▰▰▰▱▱ likely3 points

  • Canon establishes Duncan Idaho as a serial ghola whose incarnations are not identical to one another. His body was sold to the Bene Tleilax as that of a master swordsman, an adept of the Ginaz School; Leto II, ruling as a sandworm-human hybrid for 3,500 years, continually had an Idaho ghola to serve him and would order another from the Tleilaxu after each death, of whom only nineteen survived long enough to die what was considered a natural death. What arrived varied: gholas originally possessed artificial metallic eyes due to an initial problem with the method of ghola production, later resolved so they possessed natural eyes, and one ghola's prana-bindu inheritance was altered by the Bene Tleilax so his reflexes would match in speed those of anyone born in current times.▰▰▰▱▱ likely5 points

  • Canon establishes Face Dancers as a sterile race of metamorphic transhumans engineered by the Bene Tleilax, born from axlotl tanks and unable to breed on their own,. Possessing more muscle and nerve linkages than natural humans, along with advanced prana-bindu training and a specialized insight into different psyches, they could easily replicate the appearance, voice and personality of other human adults regardless of their age, build, height or sex, and their name came from the fact their facial features would appear to dance when their flesh and bones reconfigured. Their own default form is described as two small men as alike as twins, with almost chinless round faces, pug noses, tiny mouths, black button eyes, and short-cropped white hair.▰▰▰▱▱ likely4 points

    • Also known as Shape Changers and Jadacha hermaphrodites, Face Dancers were a sterile race of metamorphic transhumans engineered by the Bene Tleilax. Born from axlotl tanks and unable to breed on their own, their standing in Tleilaxu society fell below that of the child-like Master, but their fluent ability to manipulate both form and personality made them popular for numerous offworld rolesFace Dancer - Dune Wiki analysis

  • Canon establishes that early gholas did not remember their original lives. Up until the time of Muad'Dib they were created to give people some comfort from the grief they experienced after the loss of someone close, but that relief was limited because the gholas never remembered anything from their original lives. The Tleilaxu had long theorised that a ghola's original memories could be reawakened, a theory resting on the concept of genetic memory and on collected evidence that gholas could experience echoes of their past life, feelings stirred up from sounds or smells.▰▰▱▱▱ likely2 points

  • What an axlotl tank actually is gets stated at two different strengths. On one telling it is a suspicion confirmed only by inference: the Bene Gesserit suspected the tanks were what remained of female Tleilaxu, since no Tleilaxu females had ever been seen, and the remark that neither she nor any of her sisters would become an axlotl tank elicited shock from the Master, a reaction that indicated the suspicion was correct. On another it is flatly revealed that the Tleilaxu used their female individuals for creating axlotl tanks, women bred to be ghola and Face Dancer creating machines.▰▰▰▱▱ roughly even chance1 against2 points

Moreover, the Reverend Mother Superior Alma Taraza, during the time of the Honored Matres, told Tleilaxu Master Tylwyth Waff that neither she nor any of her sisters would become an axlotl tank.

One account states that he had the memories of the original and the memories of all the other gholas and that how this came about was never explained.

  • Treating the identity of the old couple who haunt the last ghola's visions as a settled matter of thinking machines, rather than an open Face Dancer question, follows the continuation novels rather than the earlier books. In the later Dune sequels written by Brian Herbert and Kevin J. Anderson, Marty and Daniel are revealed to be representations of ancient artificial intelligences Erasmus and Omnius, and readers are told the old couple are actually the computer-entity Omnius and the robot Erasmus. Yet in Frank Herbert's own text Duncan suspected, although was not sure, that they were independent Face Dancers, and the authors confirmed that Daniel and Marty being Omnius and Erasmus was not an element present in Frank Herbert's notes and is an entirely original invention.Refuted byDaniel was an entity who appeared in the visions of the final incarnation of Duncan Idaho.

  • The general statement that gholas possessed most, if not all, of the memories of the source human does not extend to every Duncan Idaho remembering the ghola lives in between. The last Idaho ghola of the Bene Gesserit had the memories of the original and the memories of all the other gholas, but most Duncans only possessed the memories of the original Idaho, and the memories of each rebirth of Duncan would pick up with his death on Arrakis, so some incarnations had abilities which others did not.Refuted byAfter a brief period of mourning, the God Emperor would order another Idaho ghola from the Tleilaxu.

  • Treating a ghola as simply a clone drops the distinction the lore draws between them. A ghola is often described as a type of clone, but to be considered a true ghola the cells used to grow it were collected after the original human had died, whereas a clone is grown from cells collected while the original human was still alive, and clones do not possess a death memory when the original memories are restored.Refuted byTo be considered a true ghola, the cells used to grow the ghola were collected after the original human had died, whereas a clone is grown from cells collected while the original human was still alive.

  • Whether a ghola with his memories back is the same person or a copy carrying that person's memories is left open rather than answered. The text puts the question to him directly, asking whether he would prefer to be called Hayt or Duncan Idaho, and the doubt is shared on both sides: Paul struggles to decide whether the ghola is Hayt or Duncan Idaho, while the ghola himself struggles with his identity, at times flooded with memories of the past and at times acting under Tleilaxu orders programmed into his brain. Even after the awakening the outer appearance remained similar while an inner metamorphosis had taken place.▰▰▰▱▱ likely3 points

  • Whether a Face Dancer has a self of its own underneath the copies is left without a settled answer. Their psychology is described as a lack of self-identity, more akin to hive creatures with no apparent ethical code beyond preserving their own life unless ordered to die for their Masters, yet Face Dancers come to believe they are the people they have copied and elude their genetically programmed loyalty to the Tleilaxu Masters, with all former loyalties nullified by their stolen psyche. Where the record touches a Face Dancer's own inner life it states its own uncertainty: it is unknown how long the one system of honor they did possess persisted into later eras, and of the entities appearing in the visions of the final incarnation of Duncan Idaho, he suspected, although was not sure, that they were independent Face Dancers.▰▰▰▱▱ likely5 points
