Hiya, thanks for the in-depth feedback!
reading it back cold now, I definitely see what you're saying about the cover/truth overlap. they were written pretty far apart from one another in production, and considering how space is at a premium, I could've helped myself with an edit there! Stat blocks could have been good use, I also would have loved to get into those NPCs a little more with the extra space. Or even just more "illustrative" notes for wardens on the levels, as I've seen in other modules here -- sounds, smells, sights were not at the forefront of my mind when I was writing. Re the text on blue -- I could definitely see that, I'll pass it on to my layout teammate for if/when we do a second draft!
Thanks again, this is all great (& actionable) feedback! Cheers!
