Catch up
Having caught up on like 5+ years of lore or so that I have missed I can summarize what I have found out as:
Farsight killed a few Orks and Daemons
Nazdreg teleported somewhere
Leviathan launched another thus far failing offensive
The Ynnari lost all their allies and are going insane (absolutely sucks for how much effort Malys, Sylandri and Eldrad put into this only for it to amount to nothing. Sylandri hasn't reappeared since, probably hiding from the sheer fucking humiliation of it all)
Squats are back as the Leagues of Votann aka we have Space Dwarves now, that is cool
Female Custodes exist which is overdue even if I do not like the faction since it is just another level of Imperium wankery
Fulgrim is around but seems not to have done much
Cawl basically already perfectly understands Necron tech and stabilized the Raukos Pit
Necron are about to lose again against the Ultramarines, which is becoming the favourite hobby of the Necrons at this point
There's a new Daemon Vashtorr who is the most competent Chaos character in a LONG time even if said competence, again, requires him to constantly lose fights but then afterwards insist that 'it's all according to plan'. Still, I personally think Daemons are vastly underutilized in the setting and far too weak, so I enjoy this addition. Would have preferred it even more if it was a Xenos Daemon Prince at last.
Oh, and, of course the only development which actually matters:
MOAR PRIMARCHS MOAR PRIMARCHS ONLY PRIMARCHS MATTER WELCOME TO 40K THE STORY OF PRIMARCHS WHAT IS THAT YOUR FACTION DOES NOT CONTAIN A PRIMARCH? CONGRATULATIONS YOUR FACTION IS IRRELEVANT AND WILL NEVER AMOUNT TO ANYTHING
The sheer humiliation of Angron returning to lose his only fight of consequence right away is painful even for someone like me who finds Khorne a bit boring.
Yuck
Welp, caught up now on the lore, I guess.
