You Maniacs! You blew it up! Ah, damn you! God damn you all to hell!
With that out of the way. Games Workshop has finally gone and done it, Cadia has fallen. A living saint backed up by the entire remnants of the Vlka Fenryka (See, Wrath Of Magnus [https://www.youtube.com/watch?v=6adES3Z0Qag]), a huge number of Black Templars, an Archmagos, the Cadian Guard, etc, are all there on Cadia trying their damndest to hold off the hordes of Chaos.
As the title of the book may have spoiled it, Cadia Falls. The Asshole Trayzen decides to drop by and grab some new pets for his collections via his Inquisitor 'buddy'. Belakor gets into a slap fight with the Imperial Fists with "INFINITE DEMONS" before The Legion Of The Damned show up and bail out the Fists... Then they decide "Yeah shit's about to go down, let's wait around here."
And then Ol' Armless's army lands... and everything starts to go wrong for the Imperials, fortresses falling all over the place, everyone's being driven back, the Sisters Of Battle just get shredded while the Dark Angels are getting Plague Bombed from orbit and the Wolves are running around biting everyone's ankled... And THEN the Living Saint turns up... Yeah this is one of THOSE stories. And the Imperium is STILL losing. Just getting pushed back and back. The Magos' are desperately trying to fix up the pylons to use them against Chaos, and who else shows up and talks his way into helping out with this but Trayzen... Yeah, that's not going to work out well, he's Trollzen for a reason.
Celestine the Living Saint goes toe to toe with Abaddon while the Magi finally get the pylons working and they produce a shield around the planet and drains the warp from everything there. Armless gives 0 fucks about that though and wounds Celestine, then gets burned and boiled by a psychic inquisitor, then throttles the Tactical Genius himself before Celestine stabs him through the back... And then... the shield falls before Abaddon's fleet, and Cadia Falls. The pylons give out and the planet breaks apart...

So, there's the fluff, I'm still looking through the rules, what does everyone think about this book so far?
