Oh shit, another WH40K RP by [@Jbcool]. I'ma have to get in on this one, I think. I might sign up as a Navigator, since those are necessary for the ship to get anywhere intact... actually, since it's relevant, it might be an idea to lay out in the OP what roles are necessary for the secure running of an Imperial Voidship, just so everybody knows what gaps need to be filled by PCs.
