Editing Warhammer 40,000 8th edition (section)

=====[[Blood Angels]]=====
*The Blood Angels and their successors (except [[Lamenters|those poor bastards]]) get fucked up pretty badly by the Tyranids, (those poor bastards were still dealing with their own bugs) with the gribblies eating large parts of Baal's moons. However, a combination of the Cicatrix Maledictum messing with the Hive Fleet's bio-ships and Guilliman's fleet taking out the remaining Tyranids on Baal after the Warp settles down leads to the Blood Angels successfully repelling the Tyranid invasion. Meanwhile on Baal Prime, [[Ka'bandha]] manifests with a horde of Daemons of Khorne- the idea of anything destroying the Blood Angels other than itself is intolerable to the Bloodthirster.
**The [[Knights of Blood]], unable to control the Flaw due to the influence of Ka'Bandha, sacrifice themselves to buy time for the rest of Baal Prime's defenders to evacuate.
*An exhausted and drained [[Dante]] has managed to just barely defeat the [[Swarmlord]] in a duel. Guilliman tells Dante that he's [[awesome|one of the few people who can call him an equal]], and makes him the commander of the Imperium Nihilus. So now the space vampires are basically in command of half the galaxy, albeit the fucked-up half. Despite the enormous amount of pressure this would entail, it's said Dante has never been more hopeful and has sworn to purge the Imperium Nihilus of Chaos.
*None of the Primaris Blood Angels have shown signs of succumbing to the [[Black Rage]], but eventually it turns out they're not actually immune to it- they just hadn't been active long enough for it to kick in. They are susceptible to the [[Red Thirst]], though they have better control over it than their shorter cousins.
*Lieutenants of the Blood Angels fill one of two offices: the Sword of Sanguinius acts as a frontline commander to lead the charge, while the Warden of the Blood is the designated second in command and will become acting Captain if the current one succumbs to the Flaw.
*Seth is pretty skeptical on the whole Primaris thing, partly because he views them as blasphemy against the Emperor's work and agents of Guilliman, loyal to him before the Chapter and their gene-father, and partly because he sees them as being less true to Sanguinius' heritage due to their apparent resistance to the Flaw. 
**Somebody in the Inquisition is pissed off enough at Seth to send an [[Eversor]] to kill him. In an amazing display of restraint, Seth only beats the assassin within an inch of its life before sending it back to the Inquisition as a warning, along with the Captain they roped into helping with the assassination attempt.
*Corbulo, on the other hand, is all hot about them, seeing the whole Primaris thing as a cure for the Black Rage. However, an attack on an Alpha Legion base in which the Primaris Marines unleashed a degree of violence extreme even for the Blood Angels seems to have left him reconsidering the possibility that they may be a cure for the Flaw.
*Our favourite [[Lamenters]] got their very own NuMarines and are slowly rebuilding after "the battle with overwhelming horror of Tyranids", which suggests they somehow managed to survive running into Kraken. Anyway, things are finally looking good for them, by which we mean they aren't allowed to go extinct because it would be a relief.
*When a Chapter Master of the Blood Angels dies, the Sanguinary High Priest and High Chaplain take temporary joint rule until a suitable candidate for the role can be found. This was established as a precaution after one Captain succumbed to the Black Rage almost immediately after he ascended to the rank of Chapter Master.
*Due to the severe losses taken in the defense of Baal, the Blood Angels now maintain an extra-large (as in almost 500 strong) Scout Company, formed in part from the tribesmen that fought the Tyranids alongside the Blood Angels and survived.
*The final stages of the Red Thirst appear to cause physical mutations in addition to mental changes; when the Tower of Amareo's inhabitants were released to fight the Tyranids, they had devolved into fanged, clawed monsters with blood-red skin that walked on their knuckles like apes.
*Baal Primus is now completely bereft of life while Baal Secundus has been terraformed back into its paradisal state before the long night on the order of Guilliman.
*Mephiston has crossed the Rubicon Primaris, proving himself Lord of Death once again.
