As my hubby doesn't have the Rogue Trader book yet I've got a request for those who have XD

I would like to find more information about Atsropaths and Navigators yet I couldn't find anything (or bad at finding anything) and thus I ask if you lot could either point me in the right direction or copy-paste anything for me.

I don't need stats, more like their fluff etc.

Cheers

Holt

I assume you have checked out lexicanum.com? Tonnes of stuff on there about pretty much everything in the 40k setting.
