I'm GM for a dark heresy group playing my own campaign with six players where only one of them is an experienced dark heresy player. Despite my efforts at describing the dark and grim imperium as the setting of the game, most of my players haven't really gotten the same image of the life in the imperium. Not that it's a big problem ingame where I can give the PCs more information as the session progresses, but I would like to convey the mood and setting better to the players inexperienced with warhammer 40k, so that they don't have to be taken out of the game whenever I have to explain common beliefs and notions to them.
Such as how psykers are viewed as citizens of the imperium, and the meaning of being affiliated with a death cult in the assassins case.
If other GM's could give me their input of depicting the world of warhammer 40k to inexperienced players, or just participate in a discussion about the subject then it would just be great
