[@Enzayne][@Roosan][@Sarpedon] Let's be fair, the Tyranids probably will fuck up literally everything in the galaxy by the time they finish passing through... except maybe the Necrons, since they don't eat those guys. That said, I believe the policy about xenos on a Rogue Trader ship is as follows:

[quote]- All humanoid races will be considered - including Abhumans and the like. Those wishing to take part in the role of a Xenos character will need a darned good reason, and a darned good profile, the same going tenfold for those who might wish to role-play as a member of the Astartes. What I do not want are any Necrons, Tyranids, undercover or overt agents of the Inquisition...just use your logic for this one.

- I hope for a larger human-to-alien ration, if this tips too far toward being a Xenoscentric RP then I shall reign it back.

- Just to reiterate an earlier point; no super-human killing machines, characters are to begin anywhere from a complete novice to a veteran or someone who has 'seen things' but no more for the moment. Guard veterans, experienced combatants, and so forth.[/quote]

So, yes, you two could probably play as an Ork and an Eldar or whatever. The rules say you can, so.
