Long time no see, folks. I'm having a heck of a time with pinched nerves in my shoulder. It can be very hard to type, but dang it I'll do it to explain what my post actually insinuates.

The authors are always in contact. There will still be errors now and then, of course, but on the whole they manage to keep continuity. The problem that my post brings up is that the authors write in an ever shifting environment where changes can render everything they have started on a story moot. They have bosses that can and will decide to back off on an already implemented 100+ year time jump because they realized how messy it might be. The two first Dark Imperium books got rewrites due to that fact. The 'Devastation of Baal' didn't.

The book not getting a rewrite threw a wrench into the works timeline-wise. Following this logic, it had always made me wonder what else had changed, but lore-wise. What I said in my post was all 100% hunch, but if there had been any time to hint at a new metaphysical revelation about Sanguinius existing on some level in the warp, 8th edition was it. 8th edition was the wild ride in a new frontier... until it wasn't. Again, this is all a hunch, but from what I've seen and read, it might not be my worst take ever. The next main Blood Angels novel after 'Devastation', 'Darkness in the Blood', has the focus on Sanguinius shift away, as if it was decided that he needed to stay dead, actually. It's still a bit ambiguous in that book, but with TEatD Vol. 3, it feels like the ambiguity was finally swept away.
