I'm running a Dark Heresy game for a group we have dubbed the Three Psykerteers - three psykers moving into different disciplines, with a handful of gimme-advances in out-of-career skills so that they can investigate conventionally as well.
Long story short, they're presently scurrying around on board a particularly volatile and dilapidated Black Ship.
It'd be super helpful if anyone could give me some rough dimensions of imperial vessels, particularly cruisers and battleships, and even MORE helpful if anyone knew how many decks I could expect to be on such craft.
Help a guy out!
