I can easily expect that there isn't what I'm hoping to find, and watch this thread sink down the list, but here's hoping. Does anyone know where I might be able to find some of the "way Navigators speak"? I figure most races/groups of people have a rather specific way that they talk, with their own slang, terminology, etc. and I was wondering if, with any of the various books written about 40k material out there, if any specific to Navigators might apply. For an example:

[THE FOLLOWING IS FLUFF]

I am working on a story, of sorts, and the primary characters involved in this bit are Arin (main character, but his name might change) and Asteira. Asteira is a Navigator, and daughter/project of her House's Novator, Daedalus Volaris. They are all currently on one of the ships in the service of Lord-Captain Edric "Boss" Korvallus, doing what they do (Arin is a fighter pilot, and Asteira is the primary Navigator). Being a project, Asteira was required to get pregnant, and while so, her father decided that they should move out of the stressful situation of the ship, and retire to the relative safety of Korvallus's space station, the Shield of Vaelos, which is in orbit of an agri-world the Rogue Trader owns. Arin, being in a relationship with Asteira, but not the father, decides to accompany her. The administrative bulk of NN House Volaris is also here, and raptly anticipating the results of the project's fruition. Some of them are very prickish, though, and don't appreciate a regular Human accompanying Asteira, to say nothing of having a romance with her, and I wonder what slang word would be good for a baseline Human, as seen by a "proud" Navigator.

[FLUFF ENDS]

So, does anyone know of some Navigator lingo? If not, I am open to suggestions; the lingo needs to start somewhere. Thanks.

Depends on the house, but I imagine the only real change in linguistic culture would be the addition of extra words for warp currents and the like. Similar to the myth of Inuit tribes having dozens of words for snow, their need to discuss the vagaries of the warp with each other would of necessity spawn more descriptive terms than 'that bit of nasty over that way'.

As for books which have Navigator characters in them, Matthew Farrer's Legacy novel features several Navigators; a couple of the HH books have throwaway references as well, but they're nothing particularly special.

I'm not entirely certain how accurate this is, but apparently the original, literal meaning of 'villain' was 'servant/worker of someone who lives in a villa'. That seems like an appropriate label for a master-servant relationship between the all-powerful mutant and everyone else.
