==Loyalists==

===Lion El'Johnson===
Title: The Lion.

What's his function? If we go with the suggestion that Alpharius fucked his Legion over and caused the split, he might devote himself to counter-intelligence ops, stopping revolts, rooting out turncloaks, etc.

Besides Traitor-focused counter-intelligence, the Lion has proven to be one of the scariest motherfuckers for any Chaos warband to so much as hear about. During the Lorgar Letdown, El'Johnson gave Konrad Curze such a vicious beating that the Traitor Primarch was first to flee for the Eye Of Terror, taking such flight that he left most of his Legion to be routed and leaving him with the smallest Chaos Space Marine Legion in the current day. The Lion is said to still be tracking Konrad to this day, and subsequently Konrad is ''still running scared.'' The Lion's stoic, ruthless badassery has reached positively legendary status, and often the other Primarchs will only actually see him in person when he is called upon by the Warmaster, Horus, for an important Imperial matter. The Lion has yet to not come to one such call, and while his apparent loyalty to Horus (actually to Father's wishes, and only by proxy Horus as he is Warmaster by Emperor's decree) is a source of mockery by Traitors, in particular Perturabo who compares him to a snivelling dog delighting in the attention of his master, he is all the same an absolutely terrifying entity to Chaos Space Marines. 'Tis only the Traitor Primarchs who have the gall to insult him to his face... except, of course, Konrad Curze.

===Fulgrim===
A GOOD BOY.
With the obvious candidate for Propaganda Minister leading the Heresy, I'd say Fulgrim could do that job? Keeping the masses loyal through flawless works of Imperial art, spreading the Imperial Truth (or maybe something halfway between the Imperial Truth and worship of Big E hopefully since atheism just cripples any spiritual defenses and makes the reveal easily convert people to Chaos and answering people saying "God created everything, including science so cannot be disprove" with a bolt to the face doesn't encourage loyalty or trust to say the least) to new worlds, etc.

===Jaghatai Khan===
Title: The Khan.

Maybe the Emperor's Messenger? While Big E can of course psyker a messenger to everyone in the galaxy, if he's still capable of speech that might be a less painful alternative. Ferrying rapidly back and forth between Terra, as well as protecting messengers and shipping lanes and acting as rapid response troops, the White Scars are a welcome sight throughout the Imperium. Jaghatai is probably a decent guy, if a bit of a more less patient person.

The Emperor's Chicken-Cooking Bitchslap, more like. Racing up and down the galaxy, the Khan and his White Scars sear a constant path of destruction and ass-kicking upon the enemies of the Imperium, making record-straining jumps constantly to be on every battlefront they can manage, determined with an absurd fervour to defend Humanity and make all who would oppress or hurt them pay, and pay ''dearly''. This level of hyper-Warpjumping is only possible through the God-Emperor's direct psychic assistance in every jump the White Scars attempt, ensuring they end up as close in time and space to their target with as little incident as possible.

===Leman Russ===
Title: The Wolf/The Old Wolf/The Lone Primarch.

Russ is also known as the Lone Primarch. His Legion abandoned him, falling to hatred. They took refuge in bestial rage, the abandonment of higher reasoning and brotherhood values for the brutal existence of battle. Slowly they became less than their fellow Marines, then less than humans. Corrupted by the touch of the Gods, the Wolves fell, despite the vain efforts of Russ to avert such a fate for his sons. Twisted and contorted by Khornate and Tzeentchian energies until all that was left of them was mutated, horrific creatures, the Canis Helix having overtaken them. Their power armor fused into their bodies, lining their snapping jaws and unholy, blood-soaked claws. Little if anything left of their minds save the thirst for blood and battle, the tearing of an enemy's limbs and the miserable screams of the weak. There is nothing left of the Space Wolves that once were, save Russ. His sons, long since lost to the Warp, are nothing more than a pack of baying hounds, little more than war-beasts to the Chaos lords they serve.

Russ has since abandoned his lost homeworld and Legion. Casting off his old regalia and armor, he has taken up a simple, unpainted set of power armor, unadorned save for the word "FENRIS" on the forehead. Though his location at any given time is known only to the God-Emperor, it is said by Guardsmen on campaign that he travels through the Imperium unhindered and guided only by fate, ranging from battlefield to battlefield to annihilate the enemies of man.
Some wonder what goes through his mind. Does he still think of his sons, or has he attempted to bury his memories?

Magnus has notably avoided so much as speaking about Leman and what happened to his Space Wolves, even when prompted, always changing the subject or simply walking away.

===Rogal Dorn===
Title: The Great Architect.

Rogal Dorn, ashamed for his failure to protect Father from harm at the climax of the Letdown, ignored his brothers' calls and vanished into the galaxy in self-imposed exile, with only the Imperial Fists 1st Company following him, though they returned to Terra months later on the Phalanx without Dorn to deliver Dorn's apparent orders for the rest of the Imperial Fists. With such a hasty exile, Dorn was not present when the Emperor awoke from restorative suspended animation. Hearing of His son's departure, the Emperor is said to have wept for three days, and all remaining loyal Primarchs stayed with Him in the Sanctum Imperialis for the duration of His anguished sobbing, silent before their father as the brothers and their father, this family, took in the ramifications and gravity of the Lorgar Letdown and the loss of their wayward brothers to Chaos, including their Astartes lost to the conflict and the mass-loss of Leman Russ' entire Legion to mutation.

Though the Imperial Fists 1st Company marines refused to reveal Dorn's location to any, refusing even the Emperor several centuries down the track when He mustered His strength and asked (much to the Khan and Horus' utter seething outrage), the Emperor allowed this treason in light of it being the decision not of the marines but of their primogenitor, the Emperor's son. The Emperor said He understood Dorn's shame, and would respect His son's decisions and desire to remain hidden as he sought atonement, for that is what the marines have admitted is Dorn's goal; atonement. They claim not to even know what exactly Dorn plans to do or is doing in order to atone for failing Father.  (>The Emperor should rip the knowledge from their minds anyway.  Because if Dorn is needed and can't be contacted, things can get Grimdark real quick.  That, and now is ''not'' the time to allow Astartes to say "no" to the Emperor after the Lorgar Letdown.  No way.)
(>>He gleaned enough to know His son would come when he was ready. Ignoring the plights and feelings of His sons and pushing them around is how the Lorgar Letdown happened, and He recognizes that.)

===Sanguinius===
Title: The Emperor's Fury/The God-Emperor's Angel.

Known by his honorific, "The Emperor's Fury", Sanguinius travels the length and breadth of the Imperium, enacting His will. Despite his title, most of his duties are explicitly non-violent in nature; resolving diplomatic crises that could see entire sectors embroiled in civil war or heretical uprisings, planning the overall strategy of a Crusade, or spreading the word of the Emperor to worlds led astray. Few know why the Primarch of the Blood Angels, one of the finest warriors in the galaxy, avoids conflict so. Some theorize he has been horribly injured by Lorgar during his duel with the Arch-Traitor, no longer able to lift a blade, but those who have seen the Primarch's graceful movements know this to be false. Only the most trusted of Sanguinius' inner circle, including select few 1st Company veterans of the Blood Angels, know the truth of the matter: the Primarch is constantly battling a mutant affliction known as the Red Thirst, a berserker rage that leaves him in a frenzy if it is not curtailed with meditation and the periodic psychic attunement of the Primarch to his Father on Terra through days upon days of prayer. Rare are the times when the Angel of Baal risks entering combat, and then only in the darkest of hours. He deploys alone, with long-ranged fire support, to avoid collateral damage, and once fighting, does not stop until the last foe has been butchered.

The Blood Angels Legion itself interestingly lacks the Red Thirst or Black Rage mutations from OriginalHammer, and this is a direct result of Sanguinius consciously taking in the psychic distortion of said mutations of his sons directly into himself. Though their genes are still mutant, the pronounced derangement from the mutations is suppressed by Sanguinius' willpower. No vile fateweaving Chaos God will turn his sons like they turned the Wolves of Fenris. Not while Sanguinius draws breath.

Sanguinius is also called the God-Emperor's Angel in some circles... much to Fulgrim's frustrated pouting.

===Ferrus Manus===
Title: The Iron Lord.

Ferrus Manus is currently traveling throughout the stars, attempting to repair worlds that have been left in dissarray after great wars and battles, particularly those which have seen Traitor Marine raids. The Raven Guard and Dark Angels both have a company specifically assigned to travel with Ferrus Manus to inspect such sightings, and to subsequently track the traitors if at all possible.

Ferrus travels with an absolutely massive fleet permitted to him only by Horus' assurance that Ferrus can be trusted with so much force, and the fleet's presence is heedfully marked and observed by Xenos, even including most Orks, in order to skirt around it as much as possible and avoid being swallowed and obliterated by the sheer volume of fire Ferrus Manus has at his disposal. Techpriests infest the largest of his ships and are said to be developing a new class of ship that is, in essence, a mobile forge city, able to deploy mining efforts and process the findings onboard, becoming a self-sustaining siege support vessel. Ferrus' ''Iron Horizon'' as it is now called is under scrutiny by the Fabricator-General of Mars for such rumours; the Cult Mechanicus considers it a breach of faith in spite of the Omnissiah (Big E) insisting that it is alright.

Ferrus Manus is also said to be the only Primarch to speak with Rogal Dorn these days.

===Guilliman===
Title: The King Of Macragge.

Guilliman and the Ultramarines have become the go-to force for minor insurrections and problems around the Imperium's eastern fringes. Due to their facilities and many recruiting worlds they are the largest of the Astartes forces, but due to Guilliman having to work through literal mountains of paperwork and council often with the Warmaster, the King Of Macragge had to write the Codex Ultra, a Chapter-specific guide to how the Ultramarines should be run whenever their Primarch was unavailable, although he has made several thousand addenda and changes to it since he first wrote it just a few centuries after the Lorgar Letdown.

More recently, the Primarch has been said to have stepped off the battlefield to review historical combat data with intent to revise the Codex Astartes to be more in-depth, more flexible and an improvement all across the board, after having witnessed a tragic and shameful Ultramarines defeat at the hands of Tau, of all things, having been outplayed at every turn in a brutal and wasteful sequence of losses resulting in a miserable retreat from multiple Imperial sectors to consolidate the Chapter's forces. This event is already being called The Humbling, though not to Roboute's face.

Alternately:  Guilliman brought overwhelming force against the T'au, which they barely countered with clever tactics and highly-advanced technology.  When he then brought the full weight of Ultramar against them, they realized that no tactics were clever enough and no technology advanced enough to allow them to stand against the Imperium indefinitely.  Thus, they became reluctant Imperial vassals.

Guilliman is revising the Codex Astartes to include insights gained from costly battlefield experience against the T'au.  He is also seeking ways to integrate T'au technology into the Imperium.  He knows that he must tread very carefully in this endeavor and does not expect it to achieve any significant success for centuries:  The Ethereals are resistant to accepting aliens as their superiors, and the Adeptus Mechanicus view non-human technology as blasphemous.

===Magnus===
Title: Magnus The Wise.

Magnus The Red has overseen the training and study of many Imperial psykers, making him a sort of father to many of them, as he has by and large been the only individual within the Imperial hierarchy to treat them as anything more than tools. Due to this Magnus has taken it upon himself to try and train all of them to the best of his ability, but due to the high death count and low survival rate of psykers living to become old, Magnus has become somewhat cold and distant towards his Primarch brothers, dedicating his time to trying to save as many of his “children” as he can with little time set aside for anything else.  In these duties include him and his legion launching campaigns to teach the common Imperial citizen about the psykers, and the running of the black ships(need a new name for it)(the gray vessels, the gray havens, silver sanctuaries something like that sound good?).  Along with Magnus' duty of keeping the Golden Throne running when the Emperor needs to go and do something (like use the bathroom) Magnus has very little time to do much else.

He could also have become the administrator and leader of the Ordo Malleus of the Inquisition, being the most senior living authority on the subject of the Warp and how it works, being very sobered to the deviousness of it and the true threats it poses to those who dive too deep into it without looking first after seeing the Daemonic tide on Istvaan V and the corruption, both physiological and mental, that occurred with both his traitor brothers and some of his own Thousand Sons Astartes as the Letdown went down. With having helped prevent Horus' fall (which he and Father kept on the down-low) and being entrusted by the Emperor with his new duties, Magnus' sense of duty and his appreciation for caution have earned him the name Magnus The Wise.

Another idea [Furious Finch] had was that Magnus is very specifically targeted by Lorgar, who has been shown the "truth" of the universe which some of the Eldar are desperate to cover up. Specifically, the Chaos Gods showed Lorgar... ''the OriginalHammer setting's universe.'' The extremely grimdark one. Lorgar wants to expose Magnus to the same brain-shattering psychic visions that he was shown by Chaos in order to corrupt him and turn him away from Big E and the Imperium. Through trickery and a trap (Perturabo, smug prick, was involved), Lorgar and his cohorts were successful in exposing Magnus to the psychic visions of the "true universe" where everything went so, so wrong, and in doing so expose Magnus to Warp energies straight out from between Tzeentch's perfect teeth which agonizingly transform Magnus' Primarch body into a mutant visage extremely reminiscent of his Daemon Prince appearance in OriginalHammer, to sow dissent and mistrust among him and his loyalist brothers to better drive him from them. Magnus survives this attack, both on his body and his mind, though he is taxed heavily by the experience and the terrible awful things he saw, and is only saved at all with the intervention of several of the loyalist Primarchs, including ye boi Leman Russ, and the loyal brothers reap a mean toll on the traitorous Astartes and give the traitor Primarchs a pretty solid thrashing to send them on their way as well, but are unable to prevent the physical corruption of Magnus' body from a beautiful, pure (if half-blind) Human into a red-skinned freak. Dissention indeed is sown as Corvus wants to put Magnus down then and there, expecting him a lost cause, but Leman Russ puts him in his place and refuses to allow Magnus to be field-executed, returning to Terra in person for the first time in many centuries to personally escort Magnus to safety. Debate and argument rages between the loyalist Primarchs over what should be done about Magnus. Vulkan, Leman Russ, Ferrus and oddly Fulgrim think Magnus should be monitored but isn't a threat. Guilliman, Jaghatai Khan, the Warmaster Horus, Corvus Corax and Lion el'Johnson are concerned that Magnus is now possessed in some capacity and should be destroyed before he can spread corruption further. Rogal Dorn is of course not available for comment.

The God-Emperor Himself admits to not being certain Himself of the extent of the damage to Magnus, and Sanguinius refuses to take either side, trusting in Father's eventual judgement.

===Horus===
Title: The Warmaster.

The Best Boy. Probably still the Warmaster, conquering new worlds for the Imperium and organizing the overall situation for the Imperium's vast military. Does he retain his shtick of making sure all worlds he conquers are fully integrated, or does he leave that to Guilliman (if Papa Smurf doesn’t fuck off to do his own thing) or Vulkan? I’d love to see him plan against the Tyranids at some point.
Think about how he'd react to Creed. Think about it. In in-game terms, this would basically  mean  deploying five units wherever you wish however you want with scout. Scout you Titan, Horus, and a knight and a few tanks. Why not? Horus arranges the strategic bits, and then Creed hides his units.

Despite this, his close call with the vile machinations of the traitor Erebus, and his fall only barely prevented by the timely and discreet intervention of Magnus (whom acted to save Horus directly in MidHammer instead of trying to warn Father first as in OH, and with much more time before the corruption had fully festered and turned Horus), have left Magnus, the Lion and the Emperor cautiously observant of the Imperial Warmaster for signs of subtle, lasting corruption. Not out of the woods yet.

===Vulkan===
Title: The Dragon.

With the Salamanders’ thing for helping out civilians, I could see Vulkan acting as a pacifier of worlds. Whereas Sanguinius mostly deals with the diplomatic side of things, keeping powerful individuals loyal, Vulkan would go out to the masses and rouse their support for the Imperium. Bro of everyone. Prepare to be friended. Of course, if you piss him off...

In the last few milennia, the Salamanders and Vulkan have been on the absolute forefront of every reported Tyranid incursion along with specialists within the Ordo Xenos, and have become supreme experts at combating the teeming hordes that descend from the heavens like a biblical plague. The Salamanders handle the open warfare, fending off the teeming invasion horde and torching capillary towers, while the Inquisitors scour the Imperial worlds, rooting out Genestealer cults. While the Tyranids have displayed a notable frustration, manifesting as comparatively short-sighted and short-lived invasions and sudden, violent psychic attacks, the 'Nids have not been stopped anywhere-near completely, and distant worlds not yet returned to the Imperium during the Great Crusade continue to be wholly consumed to feed the hive.

===Corvus Corax===
Title: The Huntsman.

With the Emperor’s Executioner and Terror Weapon both falling to Chaos, Corax might take over both roles, becoming the dagger in the dark that removes those Sanguinius cannot placate and terrifying into submission those Vulkan cannot convince. Obviously doesn’t take it to Curze’s extreme, though. Probably causes a lot fewer body parts of loved ones to be found in mailboxes. Instead, eloquently worded death threats, ultimatums, and warnings signed in suspicious red liquid. And sometimes all it takes is for petulant lords and nobles to see eyes in the dark and the gleam of mighty claws one night and they change their tune real fast. Problematic Xenos leaders, in particular Ork warbosses, are also on Corax' list of heads that need displacement.

Corvus Corax is The Emperor's Huntsman.

==Traitors==
===Perturabo===
Slaaneshi. His natural perfectionism developed into obsession and Slaanesh worship. Essentially replaces Fulgrim and the Emperor's Children as the Slaaneshi Legion.

Even better: TZEENTCH. Pride, envy and the coveting of another's station? Scheming to get around his lack of actual architectural talent? It's perfect for Perturabo. While the other Traitor Primarchs organize against the Imperium at large, Perturabo's actions are done in very particular spite and hatred of his brothers on a personal level. Perturabo has become infamous for his nasty quips and insults, earning him the title Perturabo the Razortongue. His Iron Warriors' minds are gradually being ground up and forgotten, replaced with single-minded bile-spewing hatred of the enemy, and many have begun devolving into Tzeentchian Chaos Spawns, slinging Warpish fireballs and teleporting through fortifications, still able to muster insults, though the mind behind them is all but gone.

===Konrad Curze===
Khorne and Slaanesh. Curze went truly mad by the end of the Letdown, and declared himself the new “god of justice”, sending his Legion on a crusade of terror across the galaxy. This caused the “years of fear” in the wider Imperium, where sectors were cut off and entire planets went mad from fear, often tearing into one another and collapsing into anarchy simply from the threats of the Night Lords, but the more space the Legion took the more fractured they became, and eventually from a combined assault by Horus, Magnus, and Perturabo(?) on the world of Contranis they were able to fight off the mad Primarch, and his Legion was shattered, never for the pieces to be put back together.

Another possibility is that Curze's sense of justice was warped by Khorne's influence until Curze went from vindictive but at least understandable acts of vigilante-grade justice to unabashed and unrelentingly vicious tyranny, unable to see reason anymore as his Legion descended into downright barbaric brutality. At the climax of the Letdown, Curze received a hellish beating from Lion El'Johnson, who was absolutely furious at his brother's vile, pitiful cruelty, and Curze abandoned his Legion as he fled for the Eye Of Terror, with the other Traitor Primarchs not far behind. Leaderless and mostly annihilated on Terra, the Night Lords Legion split down the middle into dozens of bands of Khorne-worshipping Punisher-type monsters and Slaaneshi torture-freaks savouring the terror and agony of mortals, losing the sense of right entirely. Curze is said to still be watching for the Lion to this day, fleeing mindlessly like an abused animal. Curze's actual fate is unknown even to the other Traitor Primarchs.

===Angron===
Khorne. Unchanged? Maybe we could do something fun with the Butcher’s Nails.

Without going into much detail, Angron has been very antisocial since the Letdown (shocker!) and has largely kept to himself in his little scarred corner of the Eye Of Terror, only ever so much as speaking to Lorgar, and only coming out when it is time to put the boots to the Imperium and take another shot at the God-Emperor and His lapdogs. Lot of pent-up rage in there, but rather than violence for violence's sake or self-indulgent domination, Angron seems to be trying to ''meditate'' in between Black Crusades, perhaps trying to overcome the Butcher's Nails on his own. Regardless of this apparent introspective, uncharacteristically calm behaviour, Angron is still very much one of Khorne's favourite wind-up toys, and his World Eaters are all-too eager to pillage, burn and butcher under the commands of the other traitor Primarchs.

===Mortarion===
Nurgle. Any ideas? Don’t have much.
<!---Considering that Papa N's specialty is endurance, maybe the Imperial Fists could become the Nurglite Legion, and the Death Guard become the Emprah's Reapers, silencing the worlds Sanguinius and Vulkan fail to placate.--->

Here's a yarn for you;
Mortarion's resentment of Father for having stolen his kill and trivializing his entire lifetime's worth of struggles up to that point festered and churned inside him for centuries during the course of the Great Crusade, which he and his Legion took a backseat for. When Lorgar started the heresy as a political revolt against Big E's deception of the populace and indeed His own sons, and overall hypocrisy all across the board, and just generally being a glimmering not-God jackass, Mortarion was on board right from the start, and allowed Lorgar's new sorcerers (led by that turd, Erebus) to infest his Death Guard with Chaos energies for the upcoming attempt at a Drop Site Massacre, and the Death Guard marines marched against the loyalist marines on the fields of Istvaan V in a gruesome display, spraying chemical weapons that corroded armour and set Astartes flesh ablaze with pustules and boils. The Death Guard marched even as their own bodies were torn apart, first by Bolter fusillades and soon, most disruptively for the loyalists to observe, by Nurgle mutations which split their rusting armour open like dead fruit skins and set their modified organs out in sagging lumps from gouges in their flesh. The fall of the Death Guard is marked as one of the most frightening and eye-opening parts of the Drop Site Massacre, as it revealed the new and dangerous threat of Chaos to the marines present. It wasn't just Daemons from a strange parallel dimension; it was the corruption of one's own body and mind.

Despite Mortarion's best efforts to coordinate the Siege Of Terra, the rapid splintering of their forces against the overwhelming defense saw the siege ultimately fail, though not before Lorgar fought the Emperor in single combat and reaped a mighty wound upon their Father. After Lorgar's descent into Chaos proper after they had retreated to the Eye Of Terror, Mortarion became Lorgar's right-hand man for all matters, sharing his preachy brother's seething hatred for the now "divine" God-Emperor. Mortarion is Lorgar's tactician and chief enforcer.

===Lorgar===
Chaos Undivided. Arch-Traitor. What does he do different form Horus as Heresiarch? Less Primarch, but zeal gives him more Daemons, allowing him to pull off the Drop Site Massacre, but this doesn't compensate for the legions that didn't flip, which is why the Lorgar Letdown lost far more decisively than the Horus Heresy.

Here's an idea. While his original Letdown was for the most part a political revolt because of the abuse he suffered at the hands of Father, bolstered by the other traitors who each had their own petty reasons for lashing out, in the aftermath the Emperor, in his extremely weak and almost nonverbal state, did council with his sons and the High Lords of Terra, whereupon they miraculously convinced him that for the good of the Imperium, the Imperial Cult should be allowed to form (though certainly not allowed to run rampant and take control) in order to give the massive populace of the Imperium a solid hope that things were not going to get worse, and that the God-Emperor would be there for them as the pinnacle of Man with His holy sons, the Primarchs, acting in His stead as He recovered from the attack of the unholy enemies of Man...

As he and the traitors fled to the Eye Of Terror, the bickering already starting and Erebus snarling like the nasty little rodent he is, Lorgar felt strength leave him and he looked back at the brothers he was leaving behind and the Father he had only ever wanted the love of, and saw the two-faced old coot ''ACCEPTING'' a religion surrounding himself now. Lorgar is said to have descended into a despairing, wailing fit, clawing at his own face as outrage and misery overcame him, and his bare head still retains the ugly gouge scars from his own fingers raking across his scalp to this day. He "recovered" from this epic emotional breakdown as the heretical traitors vanished into the Eye Of Terror, and soon re-emerged from the care of his Word Bearers a stoic, dedicated, ''angry'' man absolutely hellbent on preaching the glory and destined power of the "better" Gods, the Chaos Gods, in utter spite of the Emperor's failures, cruelties and overall hypocrisy.

Lorgar has lost absolutely all faith in his Father and is just as incensed at his Loyalist brothers for being somehow allowed to suggest that the Emperor was divine while Lorgar himself was punished for it. The Corpse-Emperor's precious Imperium Of Man will be consumed by Chaos, and Lorgar will be there to watch Father's hope die.

===Alpharius & Omegon===
Tzeentch. The mustache-twirling, cat-petting “I’ve been expecting you”-ing villains of 40k. Guide WAAAAAGHS! to poorly defended yet important worlds, triggering uprisings in previously thoroughly loyal sectors, generally creating copious amounts of JUST AS PLANNED. May or may not have triggered the Dark Angels’ schism. Masquerading as Loyalist. Did they have a hand in the creation of the Tau as an annoyance to the IoM?

Alternatively, Alpharius Omegon is looked upon with scorn and mockery by the other traitor Primarchs for supposed weakness, having contributed the least during the Lorgar Letdown. He, or they, are enigmatic and cagey, withholding information from the other traitors constantly, and while the traitor Primarchs admit that they have some trouble getting along these days, they at least TRY to work together under Lorgar to make the Black Crusades mean something. The Alpha Legion don't seem to be trying at all, and it's as though Alpharius Omegon has his, or their, own plans independent from the Chaos Legions, an idea which does not sit well with the traitor Primarchs or their Legions. As in OH, nobody is entirely sure whose side the Alpha Legion is on, or if they're on anybody's side at all. While they haven't been exactly caught sabotaging Chaos, Konrad Curze (or Mortarion, if we go the "Curze went fucking insane" route) feels it is only a matter of time before the truth comes out, bloody and screaming and preferably originating from Alpharius' and/or Omegon's jugular.
