Their constant Warp exposure increases the likelihood of additional activation of different parts of the Navigator genes, or even some proper Warp mutationsthemselves, causing deformations to a visage already estranged to that of a normal human. Any Each Navigator expresses at least a few of those 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 inexorably inevitably they acquire those mutations, many strive for cosmetic surgery to mask their recent disfigurationsdisfigurements.{{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 allowed revealed to the eyes of the public, sealed either in their luxurious estates or in exclusionary tabernacles aboard their ships.{{Fn|4b}}

Across the aeons throughout the [[Age of Strife]] many Navigator houses perished, and for some time many theorized theorised that a few of some rogue Navigators survived in some dark corner of the [[galaxyGalaxy]]. This hypothesis was confirmed in the most horrifying manner. It is true that among the stars some survived stranded from their kin; however, however having been abused by their peers in eugenic eugenics programs not concerned unconcerned with their subjects' well-being, their offspring fruited to nigh feral and approached ferality, devoid of human mindset : [[Navigator Abomination]]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 recognize 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|19c}}
