====Genetics====The origins of the Navigator gene Navigators are shrouded in mystery and rumour,{{Fn|2f}}{{Fn|5}} even among Navigators themselves,{{Fn|6}} but firmly placed within the different from other [[Dark Age of TechnologyHuman]];{{Fn|2f}}{{Fn|5}} various sources date their introduction to s in a number of ways: they posess a superior lifespan (even without [[M10juvenat]],treatments one can easily live up to around three or four hundred years){{Fn|7}} [[M15]],{{Fn|5}} they are never born as [[M19]],{{Fn|8b}} or [[M22]],{{Fn|9}}{{Fn|21b}} in most sources predating the re-emergence of [[psykerPsyker]]s (although classified as psykers in Mankind.{{Fn|5}}{{Fn|8b}}{{Fn|Note 1}} It is unknown whether some instances, they evolved on their owncan't possess any standard psionic gift, or were manufactured by genetic engineering;{{Fn|2f}}{{Fn|10c}} even if the consensus pointed to the latter,{{Fn|7}}{{Fn|11}} either would appear to be a response to Mankind’s need to perfect inherently lacking any [[Warp travelThe Assignment|psy rating]]).{{Fn|2f}} Since their appearance they began to extend their influence due to their crucial service within human society, forming noble houses that with waxing and waning times ultimately grew in wealth,{{Fn|7}} escaping the grasp of industrial and trading cartels,{{Fn|10d}} eventually establishing However the Navis Nobilite well before the advent primary trait of the Imperium.{{Fn|12a}} It is of note that in M41 many held a belief that Navigator gene originated from the time just before is their pineal eye, also known as their [[the Great Crusade]] which took place between late [[M30]] and early [[M31Warp Eye]], manufactured by [[the Emperor]] himself.{{Fn|2f}} Some Ordos amongst the [[Inquisition|Holy Inquisition]] suspect that the ancient stasis vaults beneath the mansions of the [[Navigator's Quarter]] nested in a socket on [[Terra|Holy Terra]] contain records of the true origin of the Navigator genetheir forehead.{{Fn|3e}} The aforementioned gene is easily lost through its recessive trait, and can only be saved for future generations through intermarriage, lost when bred with ordinary humans.{{Fn|7}}{{Fn|10c3a}}

The primary trait of a Navigator is their pineal While this third eye, nested in a socket on their forehead.{{Fn|3a}} While it perfectly fills the sensory function as either of his normal eyes do, it is also able to open a miniscule [[Warp gate]] within itself. From this from which stems all the Navigator’s powers. Although Navigators may open their third eye in an unremarkable way, the term “fully open” is used to describe the state required for its more extraordinary application. During the opening of this gate, a Navigator is able to glimpse the Empyrean in its true state,{{Fn|2f}} although their mind converts this image to a more mundane approximation; only with age does this comforting illusion recede, leaving apparent the true horror of the [[Warp]].{{Fn|2b}} Nonetheless, the ability to observe the Warp is crucial in their function as navigational officers, allowing them uniquely to have some semblance of assurance of their position within it. {{Fn|2f}} Indeed, it is the third eye that sets them as a race apart: where mankind was trapped within the cycle of the [[Warp]], feeding it until thier destruction, with their third eye the Navigators gaze upon the insanity of the warp itself without fear, read it's movements, hear its infinite echoes and endless preterbations, and in effect break the cycle. Though their resistance to [[Chaos]] is not perfect, and thousands of years of [[Warp Exposure]] has taken a toll.{{Fn|68}} While the eye always appears within a genetically pure newborn, in some cases it is located deep within the skull, requiring trepanning surgery and/or a cybernetic shutter for it to be brought to its proper spot. These surgeries commonly occur during a Navigator's adolescence.{{Fn|2f}} If, even with both of the parents being Navigators, a newborn has his Navigator gene Gene dormant, and no Third Eye to speak of, they are called a [[Typhlotic]]. Even if the child is a barren fruit of the line, they aren't known to be harmed, and are kept around, although the specifics of their role in the house are unknown.{{Fn|13b}} Notwithstanding the Navigators' toleration of their unfortunate typhlotic kinfolk, the appearance of them within a lineage is considered a threat to the house's survival. Across their history there were a few known houses who slowly but surely lost the ability to produce purestrain genestock, and at some point not even spending their whole fortune on [[bloodbroker]]s and unsound marriage arrangements is able to save the house from falling back into baseline Humanity, without any such useful abilities as their ancestors possessed.{{Fn|3f}} The Navigator Gene is easily lost through its recessive nature, and can only be saved for future generations through intermarriage. It is lost when bred with ordinary humans.{{Fn|7}}{{Fn|10c}}

Due to unspecified reasons Navigators normally keep their Third Eye hidden, covered with a bandana or any other decorative piece.{{Fn|7}} It is noted on one occasion that a Navigator only kept her Third Eye hidden when outside the safe haven of the spaceship, freely unveiling it while stepping aboard, with the notion of doing so only speculated by her peers to come with familiarity of this environment.{{Fn|14a}} In stark contrast, Navigators of the [[Elutrian Confederacy]] proudly flaunt their third eye, instead covering their mundane eyes, considering them to be of no importance to their status.{{Fn|3l}} While the most prominent of the Eye's powers is known to be extremely lethal, it is under full conscious control of the Navigator, being utterly harmless on its own without the Navigator's decision to otherwise be.{{Fn|2f}} When the Navigator dies, with their third eye inner warp gate open, the gate is maintained for an indefinite time, although whether natural decay factors in is unknown and extracted Warp Eyes can become a weapon in the hands of those careful of its danger.{{Fn|45}} Psychically inclined individuals however can still sense the eye even if covered, although no one but the most powerful of psykers notes the effect,{{Fn|15}} and most baseline humans often doubt the existence of this mythical eye, until in a rare occurrence they are given a chance to see it.{{Fn|7}} It however is often met with disappointment as it ends up being an unimpressive peculiarity,{{Fn|14a}} if not a reason to brand and detest them as a mutant on the first occasion of noticing the eye.{{Fn|14c}}

Other quirks ====The Curse of the Misborn====[[Image:Hernando Jurkantz.jpg|thumb|right|220px|A well-regarded and heavily mutated Navigator.{{Fn|16d}} Note the lack of Third Eye {{Fn|Conflicting sources}}]]In addition to the obvious mutation of the Navigators Navigator-Gene, a single black [[Warp Eye]] in the center of their forehead, other lesser mutations are a superior lifespan (even without not uncommon among the navigators known among the [[juvenatNavis Nobilite]] treatments one can easily live up to around three or four hundred years)as the "Curse of the Misborn".{{{Fn|768}} and Their constant Warp exposure increases the likelihood of additional activation of different parts of the fact Navigator genes, or even some Warp mutations themselves, causing deformations to a visage already estranged to that no of a normal human. Each Navigator can be born expresses at least a psyker (although classified few of these mutations at birth,{{Fn|2f}} and members of the same house tend to share the same mutations as psykers in some instancestheir kin.{{Fn|10c}} Indeed the eugenics programs within the Navis Nobilite, they can't possess any standard psionic giftwhich aim to create manifold strains of their genepool where each house tries to perfect an aspect of their powers through inbreeding, inherently lacking any [[The Assignment|psy rating]]).{{Fn|2h16d}}further contribute to these complications.

====Mutations====[[Image:Hernando Jurkantz.jpg|thumb|right|220px|A heavily mutated Navigator.{{Fn|16d}} Note the lack of Third Eye {{Fn|Conflicting sources}}]]Due to eugenics programs within the Navis Nobilite, which aim to create manifold strains of their genepool, with each house trying to perfect a unique aspect of their powers, the Navigators are plagued with further deformative mutations. Their constant Warp exposure increases the likelihood of additional activation of different parts of the Navigator genes, or even some Warp mutations themselves, causing deformations to a visage already estranged to that of a normal human. Each Navigator expresses at least a few of these mutations at birth,{{Fn|2f}} and members of the same house tend to share the same mutations as their kin.{{Fn|10c}} Some are still able to pass as humans when obscuring their forehead,{{Fn|16d}} some children still are absolutely devoid of any mutation, groomed by their elders to become the facade of the house in public relations, the [[Navis Scion]]s, attracting fellow humans with their exotic beauty and regaling them with the tales of their adventures. When inevitably they acquire mutations, many strive for cosmetic surgery to mask their recent disfigurements.{{Fn|12c}} Although unlikely it isn’t out of the realm of possibility for a one individual to gather the majority of the mutative expressions of their genome.{{Fn|10c}} Those whose malformations have extended so severely are known to be kept secret by their houses, not revealed to the eyes of the public, sealed either in their luxurious estates or in exclusionary tabernacles aboard their ships.{{Fn|4b}}

Across Those whose malformations which are more sinister are known to be kept secret by their palaces, not revealed to the aeons throughout eyes of the [[Age of Strife]] many Navigator houses perishedpublic, and for some time many theorised that a few rogue Navigators survived sealed either in their luxurious estates or in some dark corner of exclusionary tabernacles aboard their ships,{{Fn|4b}} hidden from the [[GalaxyInquisition]]behind a mask of wealth and luxury. This hypothesis was confirmed in the most horrifying manner. It is true that among the stars some survived stranded from Indeed, there are mutations considered too grotesque to even attempt such deception and many Navigator children are killed moments after their kin; however, having been abused birth by their peers in eugenics programs unconcerned with their subjects' well-being, family to maintain the acceptance of their offspring approached ferality, devoid of human mindset: [[Navigator AbominationHouse]]s. One notable individual of this kind was said to possess six atrophied limbs, sprouting from an elongated and grotesquely thin body, it had no mouth to speak of, nor any other facial features save its Warp eye, the last remnant of what allowed the witnesses to recognise it as a member of one of the strains of humanity, which was not even viewed as human among its people. Navis Nobilite policy to deal with those Abominations is a merciless purge.{{Fn|19c68}}

====Paternova metamorphosisMetamorphosis====

As a polity Navis Nobilite is a highly influential faction,{{Fn|4b}} which is known for patronage of both persons{{Fn|12b}} and projects,{{Fn|3e}} mostly concerned with matters of explorations{{Fn|12h}} and settling{{Fn|18b}} or re-establishing footholds of interstellar routes,{{Fn|29b}} funding expeditions to unknown space,{{Fn|12h}} bringing colonies back into the Imperial fold,{{Fn|29a}} quelling rebellions in Imperial systems with their private armies.{{Fn|30}} While each house acts as its own separate entity, they all are legally obliged to have an agreement of Paternova to back their decisions up, although this only comes to question when the consensus of allowed actions is broken,{{Fn|3l}} which might end up with the transgressing project being well in motion before Paternova relays their decision. One such enterprise of the expedition out to [[Canis Major]] dwarf galaxy was considered insane by most of the other unaffiliated houses, however when Paternova dictated their edict the fleet was already outside communicative range, and whether their plan to establish a micro-empire in the alien galaxy ended in success or failure is investigated only by the members of the misbehaving house.{{Fn|3g}}  On the other hand, Navis Nobilite keeps both their secrets{{Fn|2d}} and their monopoly on space travel{{Fn|31c}} with absolute ruthlessness;{{Fn|2d}}{{Fn|31c}} it can ruin the career of an aspiring Rogue Trader or even cast their whole noble house into the abyss of history if they were found to be in possession of one of secrets of the Navigator houses, among them the knowledge of lineages, breeding programmes and prominent [[Novator]]s.{{Fn|2d}} One is unlikely to stumble upon this knowledge accidentally, as Navigator houses don't speak in gothic among themselves, instead cultivating among themselves unique dialects of forgotten antiquity,{{Fn|2c}} and if somehow one was even to glance upon their mapping system they'd be confused with methodologies utterly alien from Imperial ones, along with divisions of space diverging from classical subsectors, mapped and named only in accordance with their own hermetic systems.{{Fn|19a}} Similarly, Nobilite has their eye out for any technology or method of travel that might threaten to encroach on their monopoly;{{Fn|12e}}{{Fn|31b}}{{Fn|31c}}{{Fn|4c}} many are outlawed due either to a technical violation of Imperial laws{{Fn|31b}}{{Fn|4c}} or simply as a favour from the [[Adeptus Administratum|Administratum]].{{Fn|31c}} Those that they aren't able to outlaw they often aggressively buy out,{{Fn|12e}} and people who acquire any of those items bring upon themselves the ire of Nobilite.{{Fn|31c}}

*When the Navigator dies, with their third eye inner warp gate open, the gate is maintained for an indefinite time, although whether natural decay factors in is unknown. Nonetheless, thus extracted eye can become a weapon in the hands of those careful of its danger.{{Fn|[45}}]
