Editing Warhammer 40,000 8th edition (section)

====[[Space Marines]]====
*To accomodate for the incorporation of Primaris Space Marines and compensate for issues with Codex tactics that have occurred over the millennia, Roboute Guilliman has made several major changes to how Chapters and Companies are set up. Rather than using the old Tactical/Devastator/Assault division that has been seen in the past, squads are now set up being either Battleline ([[Tactical Squad|Tactical Squads]] and [[Intercessor|Intercessors]]), Fire Support ([[Devastator Squad|Devastator Squads]], [[Centurion Squad|Devastator Centurions]], [[Hellblaster|Hellblasters]], and [[Aggressor|Aggressors]]), or Close Support (Bikers, [[Assault Squad|Assault Squads]], Assault Centurions, [[Inceptor|Inceptors]], and [[Reiver|Reivers]]). Additionally, the Battle Companies (2nd through 5th Company) in a Codex-adherent chapter can have up to a total of 20 squads each: 6-12 Battleline squads, 2-4 Fire Support squads, and 2-4 Close Support squads. While each of these companies is still nominally fixed at 100 men, in practice their numbers can be much higher since they can also draw additional squads from reserve companies if needed. This allows the Battle Companies to field a far more flexible arrangement of squads than they could in the past while enabling the existence of all-Primaris Chapters that would not be able to use the squad types that other Astartes typically employ.
** In keeping with the new classification of squad types, the 6th and 7th companies are now entirely Battleline squads, the 8th Company consists of Close Support Squads, and the 9th Company is formed of Fire Support squads.
**Vanguard Space Marines of all types are integrated into the 10th Company as a Scout-equivalent, and any other Primaris Marine can serve as a Vanguard Marine if needed. 
** Guilliman ultimately plans to replace the [[Codex Astartes]] completely with the Codex Imperialis when the latter is completed. 

=====[[Ultramarines]]=====
*The Ultramarines' 2nd Company is now led by Captain Acheran, as [[Cato Sicarius]] is now the head of Guilliman's Victrix Guard. Sicarius was lost in the [[Warp]] at the start of the Indomitus Crusade; while the Codex claims his fate is unknown, the Dark Imperium novel (which canonically takes place as the Crusade is ending) has since been proven that he is alive and well. All the other companies are still being led by the same Captains as before. Acheran is later slain during the War of Beasts, so it's likely Sicarius resumed his old position. 
*It is said that Cato Sicarius no longer seems to be as much of a glory hog as he once was. Many suspect that his time stuck in the Warp did much to teach him the difference between being a champion and a leader. 
*[[Varro Tigurius|Tigurius]] was nearly slain by the psychic backlash of the Great Rift's opening, but he was able to come out of his coma in time to rally the Ultramarines in the [[Plague Wars]]. He was also able to divine the location of the Hand of Darkness, and give this information to Eldrad (later leading to its recovery by Yvraine and the Ynnari).
*During the Plague Wars, [[Torias Telion|Telion]] ended up leading his entire Scout Company in defense of their training academy when it was attacked by the Death Guard. 
*Following the Plague Wars, Guilliman oversaw the rebuilding of Ultramar before being required to depart to other Imperial warzones. Afterwards, the Ultramarines are able to reclaim 3 of the 7 worlds occupied by the forces of Chaos in the vicinity of Ultramar, all while dealing with an Ork WAAAGH!
*Following intense debate about the implications of adding the Primaris to the Space Marine Chapters and discussions with Archmagos Cawl about the viability of converting existing Marines into Primaris Marines, [[Marneus Calgar]] volunteered to be the first to undrergo the "Rubicon Primaris" procedure. Despite dying briefly during the operation, he is successfully converted into a Primaris Space Marine. Varro Tigurus later undergoes the procedure.
*The [[Tyrannic War Veterans]] were officially given Guilliman's blessing in recognition for their show of adaptability in the face of a dangerous foe. Since then, many Ultramarines successors have created similar Tyranid hunter forces.
*Before being reunited with Guilliman, the XIII Legion had been known as the War Born, as the first members had been drawn from those regions in Terra that had been the last to submit to the Emperor in the Unification Wars.
*Calgar became seriously injured in [[War of Beasts]] and is recovering.

=====[[Dark Angels]]=====
*Ezekiel and other Librarians on the Rock are struck by a psychic vision where [[Luther]] had built an entire Legion on Caliban, and had survived the planet's destruction, leading them to believe there are far more [[Fallen]] than they ever knew about ''(somewhat reconciling old and new fluff, where originally the Fallen numbered hundreds, now there are thousands)''.
*The Rock gets invaded by a daemonic army led by the [[Daemon Prince]] Marbas, a former [[Fallen Angels|Fallen Angel]]. The conflict envelops the asteroid base but seemingly serves no purpose other than to cause carnage. Azrael later finds that [[Luther]] has disappeared from his cell, realising that the attack was only a diversion. Because no one else in the chapter or the entire Unforgiven knows about Luther's survival, he keeps it to himself.
*Considering how bad things are looking for the Dark Angels now that their darkest secret of all is missing and having recently suffered massive losses after they and several Unforgiven Chapters were ambushed on the world of Darkmor, Azrael orders an emergency summit of ALL of the Unforgiven Grand Masters ''(a lot of dudes, whole chapters get lost in the warp just trying reach it)'', but [[Roboute Guilliman]] crashes the party. His fears of an imminent judgement against the Unforgiven are put aside when he finds out that Guilliman has arrived to deliver Primaris reinforcements, as opposed to censure about their actions. So the majority of the Unforgiven get their Primaris Marines at exactly the same time.
**Guilliman also grants permission to the Unforgiven to continue using the [[Deathwing]] and [[Ravenwing]] in their structure in recognition of their service to the Emperor.
*Generally being hostile to the newcomers, the Inner Circle haven't seen fit to share the secret of the Fallen with their Primaris reinforcements yet (with the exception of their Librarians who are already rare enough and undergo the most stringent of testing anyway, plus they can, you know, read minds), mostly because they haven't gone through the same indoctrinations or heard the same apocryphal tales that the rest of the chapter have. While it is likely one of them will be found worthy of joining the Deathwing eventually, the newcomers only know the sanitized version of their history for now. 
**Of course, it's entirely possible to give your [[Crunch|Primaris Master <Deathwing> keyword and Inner Circle ability via Inner Circle stratagem]], so [[Your_dudes|you can write your own fluff]]
**While many of the new Primaris marines have served the chapter long enough to reach Veteran status, ''(see the new Lieutenant complete with bathrobe)'', the Chapter has not yet initiated any of them into the Deathwing or the Inner Circle. As mentioned, the exception seems to be the Primaris Librarians, who have the '''DEATHWING''' keyword in the crunch. No mentions in fluff to explain why; maybe there's not much use in trying to keep mind readers out of your secrets.
**In the novel "War of Secret", it turned out that whenever a Primaris witnesses something related to the hunt for the Fallen Angels, he has his memory wiped out by the Apothecary. However, the protagonists of the novel managed to go through the proceess by injuring themselves, thus triggering the Belisarian Furnace to burn away all the injected mind-wiping chemicals. So, an Interrogator Chaplain inducted them into what was called the "Primaris Circle", whose role was to on the watch for both the Fallen Angels and the Mechanicus (for signs of heresy).The Primaris Circle was not (yet) a part of the Inner Circle yet, as only Azrael could decide whether Primaris Marines would be inducted.
** No longer the case as of the most recent White Dwarf update. An [[Aggressor]] had finally been deemed worthy to be inducted into the Deathwing (though its noted that he had been EXTRA-diligent in trying to figure out the Chapter's mysteries prior to this), while one of its Brother-Captains had to undergo the Rubicon Primaris to save his life.  Being a Primaris marine now isn't a hindrance to the induction into the Deathwing, just a willingness to play along with the Dark Angels need for secrecy. However this won't stop players from saying GW is too lazy to make Primaris Terminator armor or Bikes. As it's just two so far.
*Before the Fall of Cadia and all that ensued, all Company Masters had been members of the Inner Circle. Nowadays, both with NuMarines arriving and casualties stacking up, this is no longer the case.
*The Rock is now situated in the galactic north in the Imperium Nihilus, where the Inner Circle can more easily coordinate due to the lack of reliable communications.
*Ezekiel has another vision, this time of himself, Asmodai, Azrael, and some other Dark Angels joining forces with Kaldor Draigo to enter the Eye of Terror and rescue Epimetheus from the Black Legion. Pandorax 2: Eye of Terror Boogaloo?
**Following up on the above, Asmodai cuts a deal with the [[Relictors]]: in exchange for their help capturing a member of the Black Legion who can give them Epimetheus' location, he gives them a relic in a locked box that he claims is "rightfully" his to give and "rightfully" theirs to receive. Intriguingly, he mentions that the box is unlocked by specific genetic markers but will open for them as easily as it would open for him. In light of this, it may be possible that the Relictors may be Dark Angels successors in spite of their significant deviation from the Unforgiven doctrines (to say nothing of their own dubious loyalties).
*Rumor has it that somewhere in the Imperium Nihilus the Fallen are gathering in large enough numbers to be classified as their own Legion. Azrael suspects that Luther may be responsible for this and is making plans to move against them.
*Captain Balthasar of Dark Vengeance fame is killed, and his successor Lazarus somehow manages to become the first Company Master to cross the Rubicon Primaris despite being too wounded for even a dreadnought sarcophagus. (Should be noted that he was the inducted into the Inner Circle, becoming the first Primaris Marine welcomed into the Circle.)

=====[[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.

=====[[Imperial Fists]]=====
*As revenge for the Iron Warriors' attack on [[The Phalanx]], the [[Imperial Fists]] fight alongside several Knight Houses to capture the Iron Warriors' recently fortified world of Ironhold.
*The Phalanx was badly damaged between the events of the fall of Cadia and the Iron Warriors' attack, but it was able to survive. It is now currently orbiting Terra for repairs and purification of the tainted parts of the ship. The Custodes took this opportunity to plant agents aboard the Phalanx just in case the Fists ever turn to Chaos and try to turn it's guns on Terra.
*[[Vorn Hagen]]'s dead, only two editions after he was introduced. While it's said he fell defending Terra (presumably from the Khornate reaming that followed the Rift). the fact that it came with as much fanfare and note as former Chapter Master Vladimir Pugh's passing only notes how impactful he really was.

=====[[White Scars]]=====
*The White Scars are badly depleted by Chaos attacks led by the [[Red Corsairs]]; only the arrival of [[Kor'sarro Khan|Kor'sarro Khan's]] forces from the Damocles Gulf prevent them from being wiped out entirely. Shortly afterwards, the Indomitus Crusade's reinforcements are able to save the chapter. With their numbers restored, they embark on a major campaign against the Red Corsairs that culminates in the invasion of a space station seized by [[Huron Blackheart]]. Jubal Khan and his honor guard reach the heart of the space station; though they are able to detonate its reactor, collapsing corridors prevent them from evacuating the station. Their fate is unknown, but it's looking increasingly likely that Kor'sarro Khan is going to be promoted just like Shrike was.
*It turns out that Jubal had survived, but was horrifically tortured by the Red Corsairs when he was recovered; despite the best efforts of the Apothecaries he is not expected to be able to fight again. He is now interred within the strategic center in the chapter's Fortress-Monastery, acting as a strategist for the Chapter.
*After the repelling the Red Corsairs' invasion of Chogoris, Kor'sarro Khan undergoes the Rubicon Primaris. Upon finding out about this, Jubal Khan has a private conversation with Kor'sarro, and gifts him the Cyber-Berkut Anzuq. Some within the chapter suspect that this is Jubal's way of keeping a tighter leash on Kor'sarro for his recklessness since Anzuq records all it sees.
*Chogoris has been badly affected by the presence of the Maelstrom as well as the aftermath of Huron's invasion. The mountain beasts have begun to mutate, multicolored fires burn across the plains, and even the ritual scars on the faces of the tribes' best warriors seem to reflect the shape of the Great Rift. The White Scars have consequently taken extensive precautions to ensure that their initiates are uncorrupted.
**Worse, much of the Yasan Sector that Chogoris is a part of remains under the control of Chaos forces, giving them a staging area to assist the mutant hordes and cultists remaining on Chogoris.
*Rumor has it that Jaghatai Khan entered the Webway Portal from which he never returned from not because he wished to pursue the Dark Eldar, but because he saw it as an opportunity for freedom without limit upon an endless plain to make war in. This view is bitterly opposed by most of the White Scars, but only the Khagan himself can be said to know the truth.
*After suffering defeat at the hands of Hive Fleet Hydra on Haadekh, the White Scars get revenge on the volcanic world of Horatian Utukh. Equipped with enough flamer weaponry to burn the Tyranids before they could regenerate, the White Scars lured the Tyranids onto unstable fields of rock and lava until it collapsed under the weight of all the extra bioforms formed by the death throes of leader organisms.
*Captain Jurga of the 1st company is interred within a dreadnought after being wounded by a Lord Discordant of the Red Corsairs during the War for Chogoris.

=====[[Black Templars]]=====
*The Black Templars take it on themselves to defend Imperial Shrine Worlds from Word Bearers-led Chaos forces, with several crusades being launched to drive the traitors back. Despite heavy losses, they are able to '''[[Imperial Guard|HOLD THE FUCKING LINE!]]'''.
*[[Helbrecht]] has taken a break from pursuing [[Ghazghkull Mag Uruk Thraka|Ghazghkull]]; the [[Primarch]] managed to convince the High Marshal that his oath to slay the Ork warlord had blinded him to the more immediate threat of the Ruinous Powers, and he soon declared his crusades to protect the worlds of the [[Ecclesiarchy]] from Chaos.
*A crusade into the [[Maelstrom]] finds new allies. The [[Star Phantoms]], [[Libators]], and new Black Templar Primaris marines join the crusade to purge ork pirates and chaos renegades. The crusade also recovers a lost knight STC from the Forces of Chaos.
*Black Templars are retconned from being incorruptible while simultaneously having their character who had a model in 3rd edition declared Excommunicate Traitoris. Rip Castellan Draco.

=====[[Salamanders]]=====
*A lesser known gene-seed quirk of the Salamanders grants them a limited ability to see infrared emissions. This "fire-sight" can be used alongside specialized materials to produce decorations and tactical markings that only the Salamanders can see. 
*The Salamanders deploy at full Chapter strength to fight against the invasion of the Largos System by the [[Bloodthirster]] Khaz'khul. Their new [[Aggressor]] squads (equipped with flamers, of course) prove to be the key to victory. The Salamanders soon become well-known for their effective use of Aggressors.
*The Salamanders fight and defeat the forces of the Death Guard and the Deamon Prince the Eater of Lives in the Ybrannis System, preventing millions of infected foodstuffs from being distributed across the Imperium.
*On the [[hive world]] of Parshamesh, the Salamanders prove vital in rallying the Parshamesh PDF to drive out invading Dark Eldar raiding parties.
*After the Genestealer Cult of the Innerwyrm infects the agri-world of Slathergraft, Captain Agatone leads a strike force from the 3rd company to the planet, only to find it deserted. Descending underground, the strike force finds the world's populace enslaved by parasitism, and cull of the entire underground of every living thing and Genestealer. Though successful, only Agatone and a quarter of the strike force survive to return to the surface.
*The Salamanders team up with Sisters from the Order of Our Martyred Lady to defeat a mixed warband of Iron Warriors and Death Guard marines on the word of Shen'tzi Vo. Luring the warband into a killzone, the Salamanders and Sisters launch nuclear munitions and promethium, burning heretic and loyalist alike. Though many loyalists survive, the warband is not so fortunate and are eventually driven off world.
*While fighting a rebellion alongside the Death Korps of Krieg and Voltern Cuirassiers on Hespher II, captain Shoen'lo clashes with the Death Korps over how to deal with the rebels. Shoen'lo desired repatriation and punishment for the rebels that repented, while the Death Korps wanted to kill 'em all and let the Emperor sort them out. Things came to a head when the Death Korps shelled a hab-complex while the Salamanders were undergoing a search and capture operation. Though the Salamanders were unscathed, Shoen'lo marched up to the Death Korps' command [[Leviathan]] to confront their leadership. After leaving, onlookers bore sight to something they never would have imagined to see: genuine terror among the Krieg officers. The Death Korps would go on to fight exactly as the Salamanders wanted, and the two forces parted on frosty terms.
* A group of Salamanders are stranded on the world of Warsylask thanks to the Great Rift. Suddenly, a cult of Nurgle arises and spreads a contagion that leaves only the planet's holy sites free of taint. The Salamanders leave the safety of the holy sites to take the fight to the cultists. By the time the Great Rift and plagues recede and the Imperial Guard and Arbites are able to mobilize, the cultists are a spent and broken force. unfortunately, none of the Salamanders survived the plagues, and the Planetary Governor raises the Cathedrum of the Nine Heroes on the sight of the Salamanders final victory to honor their sacrifice.
*While it is stated that the Salamanders have never been confirmed to have any successor chapters, it is also suggested that some chapters such as the Black Dragons and the Storm Giants may have been descended from them. 
*A couple of tweaks have been made to the circumstances behind [[Vulkan|Vulkan's]] disappearance in order to reconcile the old fluff with the revelations made in the [[Horus Heresy]] and War of the Beast novels; the new story is that according to the Salamanders Vulkan led them for about a millennium after the Horus Heresy (i.e. right around the time the War of the Beast happened), at the end of which he bequeathed them the Tome of Fire and left for a special mission of some kind.
*The Chapter's persistently low numbers have been retconned; they now keep 7 companies as a homage to the 7 warrior-houses of their old Legion; while each one is larger than a Codex-compliant Company, their Scout company is said to be less than half the size it would be in other chapters due to Nocturne's small population and an especially meticulous selection process.
*During the [[Age of Apostasy]], [[Goge Vandire|Goge Vandire's]] right-hand man Arch-Cardinal Perigno declared the Promethean Cult heretical. Following his decree, three orders of the Sisters of Battle attack five of the Chapter's companies on the world of New Folly alongside numerous fanatics. The Salamanders fought only in self-defense, and when news of Perigno's execution by the Inquisition arrived the Ecclesiarchal forces disbanded.
*In spite of fears that Vulkan's relics have been rendered impossible to recover by the Great Rift, Vulkan He'Stan has not lost hope. In fact, he has learned that a clue to the location of the Unbound Flame may be hidden on an obscure planet called Zero.

=====[[Raven Guard]]=====
*A Chapter-strength strike force spearheaded by a mix of Inceptors, Grav-chute equipped Reivers, and [[Thunderhawk]]-deployed [[Assault Marines]] led by [[Kayvaan Shrike]] is able to liberate the mining world of Safinyius mere weeks after it is captured by the [[Night Lords]].
*The Raven Guard, to no one's surprise, make heavy use of the Vanguard Primaris Marines.
*It appears that Kayvaan Shrike has also crossed the Rubicon Primaris, becoming the first known example of <s>emo</s> [[Beakie]] Primaris Marine.
*For the first time in centuries, Kayvaan Shrike calls a conclave of the entire chapter leadership, only to give each of them secret orders and ordering them to scatter across the Imperium. Only Shrike knows the true goals of the missions he handed out to the chapter's Shadow Captains.
*On the world of Xalladin II, Kayvaan shrike learns of growing tensions between the Iron Hands and Imperial Fists while the threat of Waaagh! Boneskar remains. Shrike discovers that the Iron Hands are after a lost relic being used to power Xalladin II's planetary shield, which removing would leave the populace vulnerable. Shrike secretly destroys the relic and reveals himself and the Raven Guard in order to force the two chapters to repel the Waaagh! In the aftermath of the conflict, neither the Iron Hands nor the Imperial Fists are able to pin the relic's destruction on Shrike, but suspicions are abound.

=====[[Iron Hands]]=====
*[[Medusa]] falls under attack by Chaos soon after the Great Rift's formation. The ensuing defense quickly becomes the largest armor battle since the Battle of Tallarn, but the overwhelming firepower of the Iron Hands' mobile fortresses ensures their victory. 
*Afterwards, the Iron Hands launch a scorched-earth campaign that leaves many of the nearby worlds ruined but free of Chaos taint. They manage to discover a possible pathway through the Great Rift and defeat the Chaos forces defending it, but the fleeing renegades destroy the portals used to sustain the pathway before the Iron Hands can secure it.
*A relic known as the Brimstone Heart is stolen from the Gorgon's Forge by the Kabal of the Bladed Lotus. Clan Haarmek goes in hot pursuit of the relic, only to lose it again at the hands of Trazyn the Infinite. Iron Captain Tyrrod is stripped of his rank for his failure and must embark on the Silver Pilgrimage.
*The Brimstone Heart is tracked to the world of Xalladin II, and Clan Raukaan is ordered to recover it at all costs. The Brimstone Heart is being used to power Xalladin II's planetary shield while the Imperial Fists fight to save the planet's remaining populace from an Ork Waaagh! The two chapters nearly come to blows over the relic until it suddenly explodes and removes the planet's shields. Though both chapters are able to repel the Orks with help from the Raven Guard, relations between them are now strained.
*The Iron Hands and several of their successor chapters embark on the Iron Crusade to protect the Stygius Sector. Currently, they are protecting the surviving worlds in the Mordian System and securing the refineries and shipyards of the neighboring Khravos System.

=====[[Crimson Fists]]=====
*The Crimson Fists were able to receive much-needed Primaris reinforcements during the Indomitus Crusade after Guilliman drove off the forces of the [[Daemon Prince]] Rhaxos from Rynn's World, marvelling when they learned that many of them had lived while their Primarch still led them. As a show of gratitude for Guilliman's role in restoring their Chapter to its full strength, the Crimson Fists have since named the day in which they were united with their Primaris counterparts as the "Day of Renewal". Guilliman personally praised [[Pedro Kantor]] for his services to the Imperium, remarking that [[Rogal Dorn]] would have been proud of him.

=====[[Space Wolves]]=====
*When the Codex Astartes was first introduced, [[Leman Russ]] somehow managed to convince Roboute Guilliman to let them retain their traditional structure. 
*Vorek Gnarlfist has been appointed the new Wolf Lord of Egil Iron Wolf's Great Company after the death of his predecessor, Orven Highfell, on [[Cadia]]. 
*Despite the return of the 13th Company, their name-stone remains blank as a symbol of all the Great Companies that have been lost throughout the history of the Space Wolves. 
*Unsurprisingly, there was some grumbling among some of the Space Wolves upon whether or not their Primaris cousins should be allowed to be a part of the Great Companies; since they were not born on Fenris and did not know of the Space Wolves' customs, some Wolf Lords believed them to be part of a ploy to undermine their traditions. Grimnar ultimately decides that they will follow the will of Guilliman and accept them, though rivalries between the Primaris Space Wolves and their shorter cousins are still common.  
**Subsequently, many Primaris Space Wolves agree to take the Test of Morkai to prove themselves worthy of being called sons of Russ. Not all of those who take the test survive it. 
*Ulrik the Slayer proposes that the cure to the Curse of the Wulfen might be found within the Primaris Space Wolves, but when several Inceptor packs give into bestial fury while fighting Dark Eldar it becomes clear that this is not the case.  
*The Rune Priests' visions hint more and more frequently that the Wolftime is drawing nearer than ever before. Njall Stormcaller is granted an audience with Bjorn; rumor has it that he sought to know every detail of the days leading up to Russ's departure.
*Wulfen Dreadnoughts are exactly what you'd think- they're [[Wulfen]] in Dreadnoughts.
*[[Lukas the Trickster]] once made a bet with [[Krom Dragongaze]] that he couldn't outstare the sun. Several hours of staring into the sun later, Krom declared the bet to be a draw when the sun went down that evening. He is blind in one eye to this day.
*Following a duel with Ghazghkull, [[Ragnar Blackmane]] crossed the Rubicon Primaris to save him from what would otherwise be fatal injuries.

=====Other Codex Chapters=====
*The [[Blood Ravens]] get their own entry in the "Unknown Foundings" section of the Codex, coincidentally confirming that they've been "gifted" a handful of Primaris Marines. It is suggested that the [[Ordo Malleus]] may know who their Primogenitor chapter is, but the records that they have are sealed. Newer fluff confirms that the Custodes were able to traverse into the Dark Imperium and provide the Blood Ravens a portion of their geneseed tithes, along with staff and equipment to create Primaris Marines, with the missive to regroup and replenish their numbers as quickly as possible (good thing too, since Sub-sector Aurelia is now stuck in the Imperium Nihilus and there's no telling how long Ulkair's prison will hold him). 
**Examination of the newcomers' gene-seed provides the Blood Ravens' Apothecaries with startling revelations about the Chapter's origins, leading to the decision to ensure that nobody outside the highest ranking members of the Blood Ravens can learn of it. 
*At one point in the past, two Space Marine Chapters ended up being formed with identical names and heraldries (the Celestial Swords). In true [[Administratum]] fashion, the mistake wasn't discovered until both of the Chapters were wiped out by the 9th Black Crusade 200 years later.
*Though it is again noted that the Indomitus Crusade was unable to liberate or even reach many of the planets that had fallen in the Noctis Aeterna, the equally important point is made that it gave the Imperium as a whole hope that it could survive its darkest era since the Horus Heresy.
*The [[Black Consuls]], formerly presumed to be all but destroyed, have been rebuilt by an influx of Primaris Marines, as have the [[Scythes of the Emperor]].
*The [[Black Dragons]] were about to be investigated by the Inquisition again, but it was called off when the Great Rift formed.
*The [[Minotaurs]] are forced to make for Terra after a Death Guard attack ruins their gene-seed stocks.
*The Angels Revenant survived destruction at the hands of the Maynarkh Dynasty in Imperial Armour 12 after the Necrons cracked open their home planet and seemimgly drowned them in lava. When the Indomitus Crusade arrived, they were ready to declare them extinct until it was discovered that a few battle brothers survived to fight the Necrons under the planet's surface. The Angels Revenant have since been rebuilt with Primaris Marines.
