Hi, I don't post here much but I've been playing 40k since the mid-90s and I'm an active mod over at Dakkadakka.com.
I've been working on an article to flesh out life for civilians in the grim darkness of the far future with an emphasis on how to create and describe worlds that are grim and dark but also credible, interesting and fun to explore.
I'd love to hear from feedback.
The first part of the series is here:

The second part here:

Let me know what you all think.
