The unnatural world of monsters contains many a nefarious shapeshifter, but few invoke such mystery as the Bene Tleilax face dancers from Frank Herbert's "Dune" universe.
To refresh, these creatures reside in a very curious interstellar civilization. After the rejection of thinking machines, space faring humans turned to their own minds and genetic destinies to manage their widespread empire -- and that's where the Bene Tleilax found their niche. These master flesh crafters use their technology to tinker with human brains and bodies, begetting clone-like gholas and various thralls on the Tleilax homeworld.
Yet, of all the forms to emerge from their axolotl tanks, the face dancer stands alone as the most fearsome and repellent.
Fiend Without a Face
While face dancers are best known -- and feared -- as spies and assassins, they play a far greater role in Tleilax society. Their talents make them unparalleled actors, so they serve as entertainers throughout the galaxy. Indeed, face dancers seem to have originated as a class of highly-trained mimes with zen-like bodily control. But 5,000 years of genetic tinkering transformed them into something more startling: beings capable of changing bodily appearance, voice and behavior to impersonate any human target.
Face dancers serve as Tleilax diplomats and conspirators, as well core operatives in the creation of so-called "twisted mentats."
Mentats are an order of human computers that helped make interstellar civilization possible in age of thinking machine prohibition. Think of them as a human smart phone for noble houses. But since mentats follow a highly ethical ethos, an unethical or cruel one demanded special preparation -- and I suppose you can think of these as jail-broken smart phones.
According to "The Dune Encyclopedia," face dancers assist in the "twist conditioning" of candidates through the systematic destruction of the individual's faith and confidence in his or her fellow humans. The details of this are rather vile: face dancers engage in atrocities with one another while mimicking key loved ones or authority figures from the candidate's life -- such as the rape of one's mother by a trusted mentor.
So how are we to understand the face dancer's unnatural abilities in light of natural-world science? Frank Herbert himself revealed little of the Tleilax's secrets, leaving the matter to speculation -- and we have two key takes on the matter.
Manipulation on All Fronts
The masterful (though sadly out-of-print and canonically-impaired) 1984 "Dune Encyclopedia" explains face dancer biology as a complex creation of training, breeding, embryonic manipulation, genetic tinkering and surgical augmentation.
Space prohibits me from going into the level of detail provided by the encyclopedia's face dancer entry, but here's a list of the key alterations:
- Selected breeding for appropriate physicality and muscle control.
- Embryonic stimulation of overdeveloped back muscles and hyper-elastic spine for height control.
- The embryonic manipulation of the body's celomic sacs, altering their position and allowing them to serve in the voluntary inflation of artificial tubes implanted after puberty, thus allowing conscious body size alteration.
- Childhood augmentation of facial structure, replacing certain facial bones with elastic cartilage, coupled with extensive training to allow total manipulation of facial features.
- Cellular embryonic manipulation to allow conscious control of scalp temperature, allowing the color manipulation of artificial, liquid crystal hair follicles.
- Genetic manipulation to enable the conscious, hormonal control of eye pigment.
- Fetal manipulation and surgical augmentation to produce male genitals retractable within a vaginal cavity for visual gender swapping.
- Training and surgery to enhance differential muscle and autonomic nerve control.
In other words, a face dancer is an extremely complex product and no mere human subspecies. But this is just one take on face dancer anatomy. For surely if the Tleilax can resurrect the dead through cloning, they can also grow their face dancers wholesale within an axolotl tanks. Our next theory explores this possibility.
The Cell Manipulation Theory
In her essay "Evolution by Any Means on Dune," science writer Sandy Field posits that face dancers mimic their targets through the conscious migration of body cells. In order to swiftly change form, a face dancer would need to reorganize skin cells, musculature and skeletal elements -- a feat they might accomplish through the dissolution and recombination of the cell-to-cell bonds that hold tissue together.
And how might Tleilax have accomplished this? Here's what Field has to say:
I suspect we might realistically land somewhere between these two takes on face dancer anatomy, which is to say I love both approaches.
The "Dune Encyclopedia" explanation (written by contributor Walter E. Myers) extends nicely from our current theories about what's possible through human augmentation. Just consult our episodes "Wind Beneath my Surgical Wings" and "The Werewolf Principle: Adapting Humans for Space." But the cellular argument feels more in keeping with distant-future technology.
Either method, however, feels convincingly Tleilax in nature.
