Editing Warhammer 40,000 8th edition (section)

===[[Chaos]]===
====General====
*A catastrophic warp storm called the Cicatrix Maledictum has effectively split the Imperium in half, stretching from the [[Eye of Terror]] all the way down to the Hadex Anomaly by [[Macragge]] and the [[Tau Empire]]. It's the damned [[Horus Heresy|Ruinstorm]] all over again!
**However, it appears that the rift is not ''completely'' impassable, as there appear to be two small corridors through it. One over by Belis Corona and the Eye of Terror called the Nachmund Gauntlet, which is currently occupied by a Household of Chaos Knights that hadn't been in contact with the Imperium since the Horus Heresy. The other is down near Cirillo Prime and the Sautekh Dynasty, which is simply called the Temporary Rift Corridor. The exact nature of these corridors is (so far) unclear, though control of them will likely be a big point of contention in the 8th Edition campaigns ([[Age of Sigmar|Realmgates anyone?]]).
*The [[13th Black Crusade]] is still going strong, but Chaos being Chaos means that a lot of the warbands have split off from [[Abaddon|Abaddon's]] main force to pillage nearby undefended worlds. However, this also means his forces have spread rather thin and might not be able to hold onto their new territory- but on the other hand the hordes of daemons pouring out of the Great Rift might mean they don't need to do so.
*The [[Chaos Gods]] have not taken the appearance of the [[Primaris Marines]] very well, and have begun brewing up [[Mary Sue]] Marines of their own powered by Warp energy.
*Nurgle has decided that the realm of Ultramar would look great as a part of his Garden, and so has released several of his nastiest plagues there along with the Death Guard and his Daemons. So far, three star systems around Ultramar have been corrupted, Espandor barely survived, Iax has been overrun by Daemons, and even Macragge is suffering from Chaos-inspired uprisings. Nurgle is sending his three greatest commanders to oversee what has become known to the Imperium as the Plague Wars: [[Typhus]], Ku'Gath Plaguefather, and [[Mortarion]].
**However, it has slowed down somewhat after Khorne (with some coaxing from Tzeentch) invaded the Scourge Stars. Tzeentch and Slaanesh showed up soon afterwards, and yet another bout of infighting was only averted by Tzeentch suggesting a competition between their Champions to decide who gets to rule the Scourge Stars. 
*Unwilling to be outdone by Nurgle, Tzeentch sent out a force of Daemons and Chaos Space Marines led by M'kachen and Magnus the Red to invade the Stygius Sector, home of Mordian and the [[Mordian Iron Guard]]. A crusade force to defend the sector was launched, but was quickly overwhelmed; only the intervention of Craftworld Ulthwe allows the Imperials to evacuate the sector. 
*Disregarding the protests of the other Chaos Gods, Khorne opened a Warp rift above Terra to let in 88 cohorts of his daemons to attack the Imperial Palace, which were driven off by Guilliman, the Custodes, the [[Sisters of Silence]], and the Primaris Marines. Khorne was upset enough by their failure to annihilate the Bloodthirsters assigned to lead the attack, but the fact they managed to attack Terra at all (and killed at least 2k Custodes) has put the Imperium on alert (more so than usual).

*Chaos [[Beastmen (40k)|Beastmen]] are now more prominent, and are being embraced more, with official GW models with various Gor using Chainswords and and an Autopistol, the bounty hunter Gor Half-horn and Tzaangors with Autopistols and Chainswords. So in other words, we may have a Waaagh! but with sheep. <s> Did someone say a Baaah? </s>

*Daemons are not immortal as originally thought; if a Daemon is unable to return to the Warp after its physical form is slain (e.g. due to the presence of the Sisters of Silence or being killed by the Emperor's Sword), its essence will disperse, destroying it entirely. Not even the Daemon Primarchs are immune to this. 
**However, there are supposedly a very small number of Daemons who cannot be destroyed this way, due to fate/casuality/the plot requiring them to be present for "The End".

====[[Chaos Space Marines]]====
*It's confirmed that some of Abbadon's Black Crusades were merely distractions, used to keep the Imperium from realizing he had been slowly destroying the network of Pylons that the Cadian Gate had been connected to. 
*The method of creating Rubric Marines has apparently been given to the Black Legion, among other warbands.
=====[[Black Legion]]=====
*Following the opening of the Great Rift, the Forge World Raeddon tries to evacuate its most sacred manufacturing relics, but is ultimately lost to the Warp when Black Legion forces destroy all its spaceports.
*The planet Aralest VII is wiped out similarly, through a combination of mass cult uprisings and an orbital docking platform being dropped onto the world's capital hive city.
*Just as the [[War of Beasts]] looks like it couldn't get any worse, [[Haarken Worldclaimer]], the herald of [[Abaddon|Abaddon the Despoiler]] arrives with hosts of [[Raptors]] and declares the world to be the domain of Abaddon over all of [[Vigilus]]' vox networks. He proclaims that the world will fall in 80 days, and by the end, Mr. Spiky Topknot himself will arrive to oversee the invasion himself. Of course it didn't work and he goes again with his secondary plan.

=====[[Alpha Legion]]=====
*Billions of sleeper agents placed within the Imperium by the Alpha Legion are activated when they foolishly look into the night sky and see the Great Rift. The resulting rebellions lead to the fall of dozens of worlds.

=====[[Iron Warriors]]=====
*[[Obliterators]] and [[Mutilators]] are confirmed to have originated from the Iron Warriors, as the Technovirus that creates them was first made in Medrengard's laboratories. 
**[[Perturabo]] and Mortarion have worked together to allow the Technovirus to spread to other machines, transforming the war machines of their foes into mechanical abominations.
*Perturabo had spent years of studying the defenses of Segmentum Obscurus; with the opening of the Great Rift, the Daemon Primarch orders a massive siege of the Segmentum's most valuable worlds.

=====[[Night Lords]]=====
*For the Night Lords, the terror inspired by the Great Rift proves to be the perfect conditions for an unprecedented level of raiding and pillaging.
*A temporary channel through the Great Rift near the Corinthe system proves to be a Night Lords trap. The Imperial ships trying to pass through the "safe" corridor are rapidly captured by Night Lords ambush forces. 

=====[[Word Bearers]]=====
*There are persistent if unconfirmed rumors that Lorgar has elected to end his seclusion on Sicarius to lead the Word Bearers personally. 
*Despite the efforts of Craftworld Alaitoc (which probably was mostly just them getting murderized by Chaos Space Marines), the Word Bearers complete a mass sacrifice of humans, Eldar, Orks, and Tau on the planet Gruelbowl. It is quickly subsumed into a Warp rift.
*Kor Phaeton personally leads a strike force consisting of multiple Traitor Legions to attack the Talledus System, a stronghold of the Adeptus Ministorum and the Adepta Sororitas.

=====[[World Eaters]]=====
*A massive force of World Eaters is en route to Terra, having been inspired by the recent Khornate incursion there.
*At one point in the past, the Wyches of the Cult of the Seventh Woe broke into the fight pits of the World Eaters on the planet Gladius. Dozens of Wyches and Traitors alike kill each other, but Khorne is so pleased by their carnage that he sends down a shower of blood to bring the slain fighters back to life. The two factions gain a degree of respect for each other, culminating in the invasion known as the Great Blood Wager of Anathema Quartus.

=====[[Emperor's Children]]=====
*As predicted by many fa/tg/uys, [[Fabius Bile]] becomes obsessed with capturing and dissecting Primaris Space Marines from the moment he first witnesses them in action. He now seeks to find a way to blend them with the power of the Warp to create his own Chaos Primaris Space Marines, and ultimately hopes to clone Roboute Guilliman himself.

=====[[Death Guard]]=====
*A recap of the history of the Death Guard, including [[Mortarion]]'s early life on Barbarus. Mortarion's "father" is confirmed to be an alien. It's strongly suggested that Mortarion took the Emperor's killing of his foster as a thoughtless dismissal of his life's struggles against the overlords of Barbarus, and that the ensuing resentment was what eventually led him to side with Horus.
*The Death Guard's organization is discussed; much of it is very similar to the old Legion organization, albeit split into groups of 7 instead of groups of 10. 
**Specifically, it is split into 7 Plague Companies, each of which is composed of 7 Sepsis Cohorts. These in turn are split into 2 Maladictums, which are themselves composed of 7 Colonies. In practice, these all tend to deploy as smaller warbands known as Vectoriums. 
**Brief descriptions of each of the Plague Companies are given; each one is led by a Lord Commander that acts as the host of one of Nurgle's foulest diseases. Predictably, Typhus is Lord Commander of the First Plague Company.
*Typhus and the First Plague Company have focused much of their activity around what used to be the Cadian Gate, generally making life miserable for the Imperial forces trying to hold onto it. 
*Typhus and Huron Blackheart duel on the world of Danasar. Typhus wins, but allows Huron to survive as a show of Nurgle's generosity.
*The Death Guard defeats the Iron Warriors to claim control of the Temple of Ascension, with the duel between Mortarion and Perturabo lasting for seven hours.
*During the War in the Rift, [[Ka'bandha]] is banished by Mortarion using the plague-ridden skulls of seven Khornate champions.
*The Foul Blightspawn and Biologis Putrefiers are the Plague Marines tasked with creating new strains of disease for the Death Guard. The Foul Blightspawn creates new illnesses through blasphemous alchemical lore, which are then entrusted to the Biologis Putrefiers to "test" on any unfortunate victims they can find.
*Plague Surgeons were once the Apothecaries of the Death Guard. However, instead of healing their brothers they now bolster the diseases that they carry. Like their Loyalist counterparts, they too harvest gene-seed- both from the Death Guard and from any Loyalist Space Marines they might encounter. Chief among their number is one Nauseous Rotbone, Mortarion's personal physician.
*[[Foulspawn]] gets a mention; while Nurgle was amused by the Chaos Spawn's antics, Mortarion was not. However, he couldn't kill it without angering Nurgle, so instead he had it banished to the Plague Planet. It has continued to grow since that time, and is now the size of a small mountain.
*Even after becoming a Daemon Prince, Mortarion still despises witches and [[Psyker|psykers]]. The only reason he allows them in the Death Guard now is because he is forced to acknowledge their particular powers as gifts from Nurgle.

=====[[Thousand Sons]]=====
*Recap of the Thousand Sons' history, the Burning of Prospero, the Rubric of Ahriman, and the Siege of Fenris. 
*Tizca is confirmed to still exist on the Planet of the Sorcerers, though it is now mutated into a twisted mockery of its former self.
*The Thousand Sons still have their cults, albeit with a very different focus beyond simply specializing in a given psychic discipline. These include the lore-hunters of the Cult of Knowledge and the reality warpers of the Cult of Mutation. A few different Thousand Sons warbands are also introduced, complete with their own color schemes.
**The further description on how each Cult is organized strongly suggests that the Thousand Sons have significantly increased their numbers since the Horus Heresy; with some extrapolation, their numbers can be estimated at approximately 65,000 Astartes (Rubricae and Living) on top of any cultists and Tzaangors that might be serving them.
*Some kind of major ritual summoning is taking place near the Cadian Gate, overseen by the Cult of Prophecy.
*The dust within a Rubric Marine still contains the Marine's remaining essence. If a Sorcerer can recover this dust and put it into a new suit of armor, the Rubric Marine will effectively be resurrected. In at least one battle, this was used to devastating effect against the Sisters of Silence by dumping a massive cloud of Rubric-dust onto one of their fortresses, which was then followed by dropping a bunch of empty suits of armor down like meteors. [[awesome|The dust reanimated the suits into new Rubrics, and the Sisters were killed]]. 
*After his encounter with Yvraine revealing the Rubric could be undone, Ahriman has determined that the knowledge he needs to learn how to do so is hidden in Commorragh.
*[[Mutalith Vortex Beast]]s are created when dozens of [[Chaos Spawn|unnameable beasts]] end up getting fused together into a single abomination, although some very unlucky Champions of Tzeentch have ended up turning into one of them right as it appeared they were about to become Daemon Princes.
*[[Chaos Dreadnought|Helbrute]]s of the Thousand Sons are not actually created from the Sons themselves due to the unsuitability of the Rubrics to power them. Instead, they lure in members of other Legions/warbands with promises of power and bind their souls to the machines. At that point [[Grimdark|the unsuspecting pilot is flayed and scorched with warpfire while he's still conscious and able to feel it]] before being installed into the sarcophagus.
*Magnus has set a plan an in motion to hyper-accelerate humanity's development into a psychic race, gathering psykers from all over the Imperium to Sortiarius by promising them safety from Imperial persecution. Though his initial ritual is disrupted by the Grey Knights and Dark Angels, the plan itself has not yet been thwarted.

=====Other Renegades=====
*Khorne Daemonkin are still a thing. The Crimson Slaughter also gets a mention, as do the other Renegades created from the Abyssal Crusade.
*Huron Blackheart seems to have struck new bargains with the Ruinous Powers, as the Red Corsairs have been reported attacking Imperial assets far outside of the Maelstrom- and Huron himself has been reported as being in two different Segmentums at the same time.

====[[Daemon|Chaos Daemons]]====
*Unsurprisingly, the only thing that prevented a complete Chaos victory after the opening of the Great Rift was the persistent refusal of the Chaos Gods to work together and press their advantage. Their fixation on the Great Game has allowed the other races a chance to renew their resistance.
*The scattering of the Primarchs was originally Tzeentch's idea, as he had foreseen that if they were left to their own devices the Emperor would defeat Chaos entirely.
*More information on the War in the Rift and the clash of champions that ended it:
**Tzeentch sought to determine the rules of the challenge, and was immediately opposed by the other three Chaos Gods. The only concession Khorne makes to the Architect of Fate's absurdly long list of stipulations is his agreement to limit the number of combatants.
**Slaanesh's champions initially claim the advantage, but after failing to halt the advance of Nurgle's forces it quickly turns into a toss-up.
**The War in the Rift ends inconclusively. Though Tzeentch technically won the Chaos Gods' contest of champions through the trickery of Kairos Fateweaver, Khorne's resulting shout of rage destroyed the hellplane that was supposed to be the winner's reward. 
*Be'lakor has been seen fighting alongside legions from all four Chaos Gods, and is said to have pledged his aid to several renegade Marine Chapters. It is believed he's plotting something, but nobody knows what it could be.

=====[[Khorne]]=====
*They remembered [[Tuska Daemon-Killa]]!
*An overview of the Blood Legions of Khorne is given. Among other types, the Red Tide Legions overrun their foes with Bloodletters while the Brazen Thunder Legions focus on mobility with Bloodcrushers and Flesh Hounds.

=====[[Tzeentch]]=====
*Tzeentch's Scintillating Legions are described. Types of these forces include the Flamer-centric Conflagration Legions and the unpredictable Legions Anarchus.
*The organization of one of the Conflagration Legions present at the Siege of Mordian is described in detail, complete with a rundown of the backstabbing conga line that comes with leading one.
*Kairos' left head lets him see into the past, and the right head allows him to look into possible futures. However, both of them are blind to the present and can only judge his current position in time by the pages written in his Tome of Destiny.

=====[[Nurgle]]=====
*Each subtype of Nurgle's Plague Legions embodies a specific aspect of decay, from the Infectius Legions that first seed his foul illnesses to the Epidemic Legions that spread and proliferate like their namesake. 
*An overview of Septicus' Plague Legion is given. 
*Horticulous Slimux from Age of Sigmar's Blightwar boxset is officially introduced into 40k. His lore remains unchanged, being Nurgle's first Plaguebearer and his chief gardener.
*A new character called Rotigus is introduced, a Great Unclean One sorcerer worshiped by the ignorant as a fertility god that has gained much favor from Nurgle in recent days. Sometimes he answers prayers, always in a predictably Nurglite manner. He is sometimes called "the Rainfather" due to the diseased storm known as Nurgle's Deluge that hovers over him.  	
*Two more Heralds of Nurgle are introduced: Spoilpox Scriveners and Sloppity Bilepipers. Spoilpox Scriveners are in charge of making sure that Plaguebearers keep counting their tally. Those Plaguebearers found performing especially sloppy work are infected with the Chortling Murrain, a disease that causes constant laughter, and are forced into the role of Sloppity Bilepiper, essentially a court jester of Nurgle who can make mortals and daemons alike literally laugh themselves to death. The Bilepipers don't last long in their new "position", since when the Chortling Murrain goes into remission they're transformed into a set of jolly gutpipes for another Bilepiper to use.
*Once Nurgle attempted to create a pox that gnawed flesh. [[Fail|It ended up acting like a disinfectant instead.]] His daemons have refused to speak of it since.
*The newest strains of the Zombie Plague cause Nurglings to develop inside their victims; when the zombie is destroyed, the Nurglings burst out and swarm anyone nearby.
*Nurgle has devised a new plague that allows his forces to bypass [[Gellar Field]]s. The "Gellarpox" infects both those individuals who maintain the Gellar Field generators as well as the generator itself, subtly influencing them to weaken the protection the field provides and eventually turning the starship the generator is a part of into a biomechanical hellscape full of mutant horrors.

=====[[Slaanesh]]=====
*Slaanesh's Legions of Excess are much more eclectic in their focuses, as befitting of the Dark Prince's arbitrary nature. The most obvious example of this is the Courante Legions, which treat battle as if it were some kind of bizarre dance right down to choreographed maneuvers. 
*Another example Daemonic Legion is shown, this time of the [[Harry Potter|Slitherine]] Host that participated in Cadia's fall.
*The Infernal Enrapturess is introduced as a variant of the regular Slanneshi Herald, playing a harp made off of the [[grimdark|intestines and muscles of a dude.]]
