Alright we have seen many mentions of Raeh's paradise on the wargear of the Blood Ravens from DOW 2. However I know this whole ordeal spawned from the stuff of "Goto"
Which I do remember a studio guy once saying in the old Relic forums that " its not canon but it is a source of inspiration as some similar events occurred on a different fashion.
So I wonder if the same thing will happen with DOW 3 Novelization? Now I take the canon story here is the game but I did read the mention of Raeh's paradise and what happened to it and it honestly bothered me.
The fact that Gabriel already faced the Necrons "despite DOW 3 spoilers advertising that they are an enemy that he has yet to encounter" Let alone commiting exterminatus on Raeh takes away the effect of doing such thing to Cyrene.
I think it would be great if that one bit was left alone like "A different Blood Ravens company rooting out the Necrons throught orbital bombardment and stuff" but no exterminatus. That's just way too edgy and repetitive, to the point where it just takes away the impact of it. Besides such thing is only done when the thing it's just completely lost to Heresy. I would even Argue that the exterminatus at Typhon was exaggerated as well.
Also no Captain Coralis? give me a break >_<
I have yet to check the comics tought.
