OK we can all agree that 40k's lore is esoteric, ambiguous, and in some cases inconstant - fine no problem!
By that logic after doing my learning here and elsewhere - one has to make 40k "theirs" as a Gamemaster
Due to the sheer amount of data available - the lore in some cases is a bit lacking - and yes in support of the unknowing almost primitive nature of man's understanding of things around him + propaganda we end up with the explanation we are given or come to the conclusion to - that's fine as well!
But for me and some others - making 40k yours involves a bit more pondering and of course solving some of the 40k mysteries whether they be fluff or rules...
So today I will post my ideas for my own 40k Universe (which someone here on the forums once dubbed the Morbidverse lol)
1. The Illustrated Men / Women of 40k (appearances)
So if you look at the art presented most of the time the humans illustrated are fine specimens rippling with muscle and erect by great posture - lol! That's fine and dandy - but why - why do humans now looks so well healthy? In the Morbidverse the Imperium of man has adopted putting nanites in their food which is passed through the system - thus its a continual process of maintenance - these nanites go to your muscles and make microscopic tears (like working out) - resulting in the statuesque humans well all see - disagree - how many fat Navigators or Skinny Scum do you actually see depicted in either visual art or the miniatures? For me this provides a plausible yet mysterious solution most people including high ups are even aware of - would most really even care - would most even know to question their state of vigor as compared to us some 38,000 past - prolly not - to them muscles and such are normal - and as such we as a species have engineers ourselves as far as we can without becoming Abhumans!
2. Las Fire (audio cues?)
I've been going over this detail on the forums as of late and will proved here a link to that discussion...
