Been wanting to post this for a looooooooooong time, especially after reading the gathering Storm lore/rule books.

I have read the trilogy, and the White Dwarf bunker extra fluff, and am sadly disappointed.
I was hoping - wringing my hands even - that there would be some friction between the ret-conned Primaris and Roboute against the rest of the Imperium.
Especially, as in the third book, Roboute thinks on his Father's vision and hopes for humanity, (ya know, that smallish goal Roboute lived for in WH30K) and decided to push ALL OF THIS TO THE BACK OF HIS MIND AS SECONDARY! WTF, GW. I was truly hoping there would be an open schism between the all-too-false religious juggernaut that is the Eclessiarchy (side note, I do LOVE the tragic irony that the Imperial Faith is based on Lorgar's writing). Was really thinking Roboute would have pushed the issue on his Father never wanting to be deified, since for Roboute only a day has passed, no 10K years.... He could have convinced Celestine that she is a psychic manifestation of The Big E, not a saint, and it sounded like there were no SoBs (that's Sisters of Battle, ya filthy blighters) left on Macragge to contend this claim, and Greyfax is a contrived nobody that GW created to sell more crap, so there's no need to even bother with her/it. Cawl is a ret-conned creation in direct connection with the Primaris, so being a project in the works for 10K FRiKKIN YEARS, one would think the Primaris would have been instilled with Roboute's beliefs, not the beliefs of the 'modern' Imperium, especially since until heretofore Cawl has been secluded working on Roboute's secret ret-con project of True-Scale Marines, not out learning about modern trends on your Rachel Ray-imperium channel.

But no.

Now there's a Primaris Chaplain (really!?!?!) According to what I've read, the Primaris are, like, totally down with the Imperial Faith yo. Very disappointed.
