40K: Fallen Sons – Your Favorite Traitor Primarch

The Primarchs Cover Art

Everyone loves a GREAT villain – so step fright up and let us know who you think is the most deserving of your devotion:

BoLS alum Mr. Mystery tees this one up:

Nice and straight forward this one, as it’s about your favourite Traitor Primarch, and the reasons behind that favour.

My one is easy:


It’s Perturabo

“One of the Emperor’s two siege masters, he got dealt an exceptionally ****ty hand. Whereas as Dorn and his Imperial Fists got all the breaks and the glory, the Iron Warriors got stiffed with the grubby, grotty hard work of laying siege, and quite often weren’t even given the honour of the kill, as other Legionnes Astartes got to exploit the breaches bought with Iron Warrior blood.

I mean, wouldn’t you be pissed off with your Dad if you did all the work, and your arse of a Brother repeatedly got the praise? And I know he’s not the only one to get the ****ty end of the stick, but he had potential.

…He was the equal of Rogal Dorn when it came to siege craft, excelling in the laying of a siege rather than building a fastness – though of course that’s a matter of perspective.

He or Dorn were essential if Horus’ uprising was to succeed. Why? Well, the Rebel Legionnes Astartes rushed to Terra, knowing their best chance came from minimising the time the rest of the Imperium had to react and reinforce, given their target was glaringly obvious.

Had Perturabo not turned, which again is entirely due to the Emperor being a dick to him, the Rebels would in all likelihood been repulsed from The Emperor’s palace with crippling losses to both men and materiel.

In the nightmare scenario for Horus, imagine if the Iron Warriors and Imperial Fists had both defended the Palace….the words ‘no chance, tosser’ spring to mind…

…But yeah. Poor old Perturabo. He didn’t deserve the treatment he and his Legion received.”


Angron? Stiffed of a glorious death, but ultimately guided too much by the brain butchery in his head.

Lorgar? Victim of a necessary censure, and really, really bad advisors. In a sense, both Lorgar’s fathers stiffed him.

Horus and Fulgrim don’t really count, as their turning wasn’t particularly self determined.

Alpharius? Listened to Xenos. Took their word for it. Prick.

Mortarion? Yeah ok, similar situation to Perturabo.

Magnus? Betrayed by Horus, not The Emperor overall. It was Horus that set the Wolves on him!

To which Pathwalker replies with his favorite:


It’s Angron

“He was a gladiator, he fought for his freedom with his brothers and sisters and was snatched away at the last minute, watched his soldiers die while he lived. The Emperor ****ed him over more than any of the others. He was damaged and broken by the Nails, the Emperor left them in because he was the butcher the Emperor needed, all the Primarchs were used, tools to be discarded, but none more so than Angron, only he and Kurze saw the big E for what he was before the Heresy, they saw that the Primarchs were to be thrown to one side when they were no longer useful. The rest only came to that conclusion after he left and set up the Council of Terra but Angron had seen how little his Father cared for lesser beings from the first moment he met him, he was truly alone from the start….

Others fell from vanity, Perterabo, Horus, Fulgrim, or necessity, Magnus, Alpharius or out of faith for Lorgar.

Angron didn’t fall, he was never loyal, he’d hated the Emperor from day one, and thought Horus’s rebellion would give him a chance for rebellion, not realising that Horus was using him as much as the Emp did.”

I’ll step in with my own favorite:


It’s Konrad Curze

Konrad always knew.

He had the greatest and the darkest gift of all his brothers – prescience.  He KNEW…

He knew what would be required to tame Nostromo from the moment he could stand.

He knew the simple rules of human society and how he could most efficiently control it.

He knew the ultimate ruin that would come to all things being built by his brothers.

He knew he would be despised by all those important in his life.

He knew there would be no forgiveness for his actions.

He knew his father would come for him in the end.

He knew in a cruel galaxy the ends justified the means.

He knew his father agreed with him.

He knew it all – and he didn’t shy away from an inch of what would be required of him.  He did it anyway.

~Rights, over to you. Who’s your favorite traitor primarch and why?

  • Eldar are Chaos now

    My favourite traitor? The Lion. He practically got away with it.

    • benn grimm

      And he would’ve gotten away with it too if it weren’t for you meddling kids….! 😉

      • ZeeLobby

        Lol. It would probably fly with the quality of current fluff.

    • Lord Elpus

      And his legion has a nice line in evening gowns….

      • Jeramy Bailey

        You take that back! These gowns work all day long!

  • Nyyppä

    I’m going with the 40k Batman though the legion does not interest me at all.

    • Master Covellio

      Really, well here is a line from my Boy Jago, I love the Night Lords,

      “Because the Wolves kill cleanly, and we do not. They also kill quickly, and we have never done that, either. They fight, they win, and they stalk back to their ships with their tails held high. If they were ever ordered to destroy another Legion, they would do it by hurling warrior against warrior, seeking to grind their enemies down with the admirable delusions of the ‘noble savage’. If we were ever ordered to assault another Legion, we would virus bomb their recruitment worlds; slaughter their serfs and slaves; poison their gene-seed repositories and spend the next dozen decades watching them die slow, humiliating deaths. Night after night, raid after raid, we’d overwhelm stragglers from their fleets and bleach their skulls to hang from our armour, until none remained. But that isn’t the quick execution the Emperor needs, is it? The Wolves go for the throat. We go for the eyes. Then the tongue. Then the hands. Then the feet. Then we skin the crippled remains, and offer it up as an example to any still bearing witness. The Wolves were warriors before they became soldiers. We were murderers first, last, and always!”
      —Jago Sevatarion, speaking about his VIIIth Legion

      • Nyyppä

        Great for you. I still don’t care about them.

      • Loki Nahat

        Hmm. That quote,… itchy fingers, my XIV might need some Allies

  • Andrew

    Fulgrim. Killer of not just one, but two Primarchs. The only other Primarch able to kill another was Horus.

    • Craig Bradford

      Fulgrim didn’t kill Guilliman, so his count is one. Russ is the current leading Primarch-killer (heavily implied that he kills the two Unknown Primarchs)

      • kingcobra668

        He effectively “killed” him for around 9000 years. The Imperium would be a much different place without that “tiny fact.”

      • Andrew

        Guilliman would totally be dead had he not been put in stasis last minute, so I still count it as a win, though maybe that’s just my Emperor’s Children fanboy coming out. 😉

        I don’t count Russ since they’ll (hopefully) never explain what actually happened to the two lost Legions.

    • william timonen

      Curze, think of how many times he has killed a primarch. : )

      • Andrew

        Oh yeah, I guess you’re right there, must have blocked that out as I thought that novel was a real slog to read through. Didn’t Vulcan pretty much beat the crap out of him once he got a weapon though? Either way, Curze is one of the better characters, a shame that they started writing his personality as a mix of the Joker and Bane from the Nolan Batman films, and didn’t stick with his more original troubled prescient character.

    • Lord Elpus

      And Russ…🤔😒 who in the fluff seems to be responsible for killing the 2 missing Primarchs… not to mention Magnus if he hadn’t been taken by Tzeentch .

      • Andrew

        Hmmm, I thought it was a last minute gamble that Magnus pulled himself to teleport his person, legion, and base to the Planet of the Sorcerors.

        • Lord Elpus

          Old fluff was that Tzeentch spirited them away newer stuff is that Magnus did it, but at the back of it was the architect of fate. if that hadn’t happened Russ would be responsible for 3 primarch deaths..

          • Andrew

            Ah, I was always quite fond of the really old bit in the 2nd Edition rulebook where a Thousand Sons sorcerer describes the ritual they used to move their Legion to their new planet. Good old vague fluff, allowing you to fill in the gaps yourself; such mystique and mystery there. 🙂

          • euansmith

            Arch-Traitarch Krang, “Are the planetary defences in readiness for the Astarte Scum?”

            Lord Lickspittle Lackey, “Yes, Lord Guv’nor! Their ships will burn with the fury of a million exploding suns! Their drop pods will be like birds caught in a wild fire. Their..!”

            Guardman Menk, “Ah-hem… the Astartes are here, Lord Traitor.”

            Krang, “What do you mean, “Here”? Why can I not hear the defence laser firing?”

            Menk, “The Astates are stood in the court yard outside… They just.. appeared… all quiet and mysterious like.”

      • william timonen

        If II and XI had been Punisher by death, Lorgar wouldnt reflect in Betrayer about how Manus death was this world-changing event that proved the primarchs was mortals. If they had died more 40 years before, Im pretty sure it wouldnt come as a surprise for him…

        Also, if we count “almost deaths” Angron was one second from killing Guillman and Curze almost blew up Guillman and Lion. Except it was Magnus actions that saved him.

        • Horus84cmd

          Hmm yes because the Emperor has never been know to omit the truth to his sons….

          The missing Legions and what happened to them is a huge cover up. There no evidence that any Primarch (even Russ, if he was involved) knew what happened.

          • william timonen

            They knew what happened, or why would Lorgar and Magnus be banned from talking about it if they werent there?

          • Horus84cmd


            All the Primarchs are fundamentally banned from talking about it and certainly, at the very least, from the glimpses we have from the novels don’t like talking about it. They’re banned by the Emperor on the matter.

            There is literally no information on the circumstances around them “not existing”. It is only alluded that Russ and the Wolves was involved; and certainly no indication any other legion where present.

            Other Primarchs, like Lorgar and Magun, may have AN idea of what happen, but that is not the same as being there or, indeed, knowing what ACTUALLY happened.

            Corax was the last Primarch but one to be found and by then the Lost Legions where already expunged from records. This is made apparent in Deliverance Lost when Corax recalls when he first meet the Emperor:

            “Yes, you have brothers.” said the Emperor, smiling at His son’s delight.

            “Seventeen of them. You are the Primarchs, my finest creations.”

            “Seventeen?”Corvus asked, confused.”I remember that I was number nineteen. How can that be so?”

            The Emperor’s expression grew bleak, filled with deep sorrow. He looked away as he replied.”

            The other two.” He said. “That is a conversation for another day.”

          • william timonen

            But Argel Tal is describing the existence of XI and II as being something that has affected him personally. Which means that the Word Bearers had to be present for whatever XI and II did. And we have a pretty clear understanding of what happened, one of them was described as a traitor. Whose legion still was innocent enough for them to be absorved into the XIII. While Sanguinus fear of Blood Angels Gene-sees flaw coming out tells us a flaw was what got the other punihed, or probably put down.

          • Horus84cmd

            Again someone describing something and being affected by it does not mean they were there. Argel Tal did not have to be there to be affected by the idea of brother legions just being wiped out for some horrendous crime against the Emperor that could not be forgiven.

            In real history there are lots of accounts of front line soldiers talking about event of other battles and those very stories themselves affecting them on a personal levels – heck potential draftees in the WW1 would injury themselves so they could not be drafted because they got so affected by the stories. Indeed on the other side, nowadays there are plenty of volunteers that go out to war zones to help refugees because they are affected by the stories they hear and want to help.

        • Lord Elpus

          Almost can’t count as it’s an almost… like almost winning the lottery IF they’d bothered to enter it.. aye they’re executed by Russ and there’s a wee rumour that their legions were absorbed into the Ultramarines…

          • william timonen

            Their legions mightvel been absorved, but if they died Lorgar wouldnt be shocked that they could actually die…

    • kingcobra668

      Russ didn’t kill at least 1 of The Two?

      • Andrew

        I don’t count Russ for either of the lost Primarchs since we never know what happened to them. And I guess Dorn killed Alpharius? Or was that Guilliman who killed him? Or was it Omegon? I stopped following the book series after the Chaos dinosaurs showed up. Picked up Master of Mankind and wasn’t too fond of it either. And now there’s a clone of Ferrus Manus that the Mechanicus were able to capture?

      • william timonen

        No, if any primarch died before Manus. There is a line in Betrayer that doesnt make sense.

        • nurglitch

          Which line is that?

      • Lord Elpus

        I though he offed both?

        • kingcobra668

          IIRC, its mentioned that he definitely offed one, but the other’s demise was shrouded in thicker mystery?

          • Lord Elpus

            He runs a cheap clip joint out Nevada way?

          • kingcobra668

            LoL, seems like the most plausible theory I’ve heard.

        • euansmith

          “The Emperor asked you to take them out? Like on a date?”

          “Oh, that’s one way of reading it. I wish he’d been more specific now.”

          • Lord Elpus

            Probably got the message as a text and misunderstood it . You know what it’s like…

  • benn grimm

    Until the HH novel series and FW books, my fave was Magnus, no competition, for being a selfless, deluded anti hero; the only loyal traitor, now it would have Lorgar, for his journey from bitter, confused sissy to bitter, all powerful conduit of the warp, Perturabo de Vinci for being the only Primarch who comes across as genuinely thoughtful or Mortarion for sheer badassitude…

  • Tlhswallow RGN

    Iron Within. Iron Without.

    • Red_Five_Standing_By

      Iron Within. Iron Without.

      • euansmith

        “I am within. I am without”, Alpha Legion.

  • william timonen

    Curze and Angron. Because they didnt really fight for any ideals. They just went along for the ride.

  • Lord Elpus

    Mortarion is mine, why well The E used them… no glory just expectation of duty and nothing else… Mort had promise of helping the weak like Vulkan..

  • Horus84cmd

    Got to be Alpharius and Omegon for me. Firstly, I really like the concept of twin Primarchs; it allows for some imaginative, twist filled story telling.

    • kingcobra668

      I’ve always hated that there were 2 dudes. 21 primarchs…

      • Horus84cmd

        Each to their own.

        • kingcobra668

          Cannot argue with that

  • Anasa

    Magnus is the perfect example of faustian bargains and good intentions gone wrong, and for that he’s my favorite. Lorgar comes second due to how his personality was portrayed in the HH series.

  • Talos2

    I like them all, maybe logar the least and curze the most, but all are great characters

  • DeCold

    Mortarion, since im collecting Death Guard.

  • My own personal top 3 fluffwise is Perturabo, Night Haunter and Alpharius.

    If I can add my own conjectures about what really happened, it becomes Perturabo, NightHaunter and Lion’El Johnson.

    In both case Fulgrim comes close to 3rd.

  • Red_Five_Standing_By

    The Emperor was an awful dad.

    • euansmith

      If only Horus had got a better therapist.

  • Davis Centis

    My favourite is Magnus the Red. Always the outsider, Magnus saw what was coming, but lost it all because he tried to help. His hopes betrayed him. How like Tzeentch.

  • Jonathon West

    Horus, he’s the best, and the most awesome. He’s the most tragic in a way besides Lorgar. Because the rest of then we’re always going to turn.

  • frank

    I love Angron but if I was the Emrah id be pretty disappointed too like come find the only primarch who didnt take over even one plannet and come to save him an he throws a hissyfit. Like he is kinda the kid that tries but doesnt really achieve anything. I think the Emprah probably had a bunch of runner up trophies from angron on his mantle that he swears mean just as much to him as all the other primarchs accomplishments but deep down hes like wow screwed up on that one at least I didnt have to kill him…
