>>Okay, so let me get this straight... Guilliman was removed from stasis and saved by the fucking Eldar?
Yep.
>> And this was sanctioned by the fucking INQUISITION?
They were not consulted. Once the Grey Knights (in the person of Grand Master Voldus), Sisters (in the person of Celestine) and the Deathwatch (it's fucking Guilliman, half of them have his gene-seed) have signed on, inquisitors are just men and women in hats with pistols; their chambers militant obey Guilliman.
Guilliman is of course, the one who sanctioned having an Inquisition in the first place. They have a dubious legal right to remove him - for all their bleating about the Emperor being the only one who outranks them, he, as Lord Commander, created them - nor the practical power to do so.
>>And there's a new chaos god?!
Ynnead existed as a potential in lore since WD127 introduced such things as 'Aspect Warriors' and 'Farseers' 27 years ago. A good portion of anons weren’t even born when they came up with it.
>>And new mega space marines that take 1,000 years to make have shown up and this one fucking tecmagus spent 10,000 fucking years building them IN SECRET?! AND EVERYONE IS OKAY WITH THAT EVEN THOUGH ALTERING THE ALMIGHTY EMPEROR'S HANDYWORK IS CONSIDERED THE ULTIMATE FORM OF HERESY?!!!!!!!!!!!!!!11111111111111
They don't take long to make at all. Guilliman met with and 'spoke' with the Emperor to recieve his orders; what makes you think he didn't get told 'make better marines' - no one can disprove that and the ecclesiarchy say he's ace.
And of course, it's been in GW lore since 2011 that Astartes were deliberately gimped by the Emperor compared to what a primarch and a technomagos could do with the primarch gene-source and the Emperor's knowledge; Raptors during the heresy were everything Primaris are, and perhaps more.

>> Seriously? What the fuck is even happening over at GW?
Plot progress. You asked for it anons.
