In Rogue Trader, how does Navigation through the Warp get done? Is the Navigator Outlaw Star's Melfina, floating in a tank, looking out at the Warp, or huddled over a great table, covered with ancient parchment maps, and datapads? Are they wired into the ship, guiding it themselves, or forwarding information to the Void-Master/Lord Captain, at the helm of the bridge? Are they alone in a room, or being aided by numerous other extras?
Is there material that describes, in detail, the how the Navigator moves the ship? I feel that a lot was borrowed from Frank Herbert's Dune, and that was a good choice, but the Guild Navigators are true psykers, more so than RT Navigators get to be (I see them more as a combo of both Astropath Ascendants and Navigators), and they use their vaunted power, coupled with the effects of Spice, to fold space, so that the ship doesn't move. There is little risk, and almost no downtime; Rogue Trader certainly doesn't do that, with month-long trips, numerous Warp phenomena, ships disappearing, etc. So what is the visual mechanic that 40k uses. I have a Navigator I wrote up, mostly for a fictional literary work, at the moment, and she would have no problem playing Melfina, mostly nude in a tank (and no one would see her, so no big problem there), but I don't know how "immersive", pardon the pun, the process is for her. For long flights, I want to imagine someone else might come in, and relieve her, but it wouldn't work if they had to drop out again, and let him get his bearings. Anyway, some description, assuming this ever got covered in a book/novel would be much appreciated. Thanks much.
