XV Legion 'Thousand Sons': Origins & History (Warhammer 40K & Horus Heresy Lore) 

The tragedy of the Thousand Sons is one of my favourite things in all of 40k.

Not even changing the serious academic tone for "if I may offer some 'gallows humor'" is just freaking hilarious.

The problem is, the fall of Thousand Sons was never set in stone. Any number of factors could have prevented their fall. While I will not claim Magnus was faultless (he was quite reckless, if understandably given his inferiority complex and subsequent desire to prove himself), he DID have the best intentions in mind. Propero was probably the closest imperial realm to utopia, only rivaled in that regard by Ultramar. The Interex and Craftworld Aeldari demonstrate that civilizations of Psykers, possessed by knowledge of Chaos, could nonetheless be a stable society. Knowledge was not the enemy. Ultimately, if any of these groups had met the Thousand Sons before the tragedies that befell them and taught them restraint, then maybe tragedy would have been averted. If Magnus has stayed and delivered his message despite his blunder, perhaps the Emperor would not have delivered that fateful order, subsequently to be twisted by Horus. If Jaghatai Khan, Primarch of the similarly psychic White Scars, happened to be nearby to help temper his impetuous brother, maybe Magnus's recklessness would have been averted. Alas, peace does not sell plastic miniatures, so we will never know.

The Ninth Legion exiting the depths of the Neptunian Volume with the friends they made along the way is so wholesome

I think the Pre Heresy Thousand Sons have one of the most beautiful Power Armor design, alongside the Emperor's Children and Luna Wolves.

If he had just packed his ship, and flown over to Terra, we could've avoided a lot of stuff.

“The Thousand Sons were no magpie hoarder of lore.” I missed this the first time watching the video. Second time my wife was concerned by the snickering and chuckling coming from the room I was in. Best line in this video. I hope others caught the reference. Well played Occulus, well played.

Dude…. This video series is showing its age the most. I collect Iron Warriors (and listen to that video 1/month for lore/writing) and comparing the two I’m pretty jealous. Nice Work!

The Thousand Sons and their star-crossed Primarch are, by a wide margin, my favorite Legion! Consequently, I'm very glad to see you finally tackling them and their history.

An hour of my favourite smooth irish voice accompanied by chants talking about one of my favourite Legions. Great day already! Happy New Year Oculus ;)

In Irish Mythology, the Ríastrad was Cúchulainn's fierce and terrifying transformation, in which his flesh contorted and he became hideous and berserk, but physically unstoppable. Though he wasn't Berserk all the time, there was that one time he fixed a castle's wall to its main hall after he walked through it. The point is, Ríastrad roughly translates for us to "Warp Spasm." Cúchulainn was the Soul Son and reincarnation of the finest high king of the Tuatha Dé Danann, Lugh Lámhada. While this figure fought for the spiritual destiny of all of Ireland's people, his race & Tribe pre-dated humans, and thus despite being the stuff of righteousness and masculinity, his essence was what caused the changes in Cúchulainn, for both his prodigious strength but also his horrific rage and form.

Being a nerd, they're my favourite legion. If I could only get into the least of Prospero's libraries, not even the Emperor could drag me out of there!

My bois 🥺 My precious little space librarians 🥺

M30: "We worship the sun." Astartes: "Die! In the name of the imperial truth!" M40: "We worship the sun." Astartes: "No problem with that. But you have to refer to the sun as the embodiment of the god emperor okay?"

Looking back, how happy was I when the lost and the damned came out. The 2nd book of chaos for 40k. And the 1000 sons actually had an army list. From all those years ago, fast forward to now, and my fav 40k lore channel has finally come to the 1000 sons. What a great moment in time.

I'm not crying, there's just some dust in my eyes.....

53:58 "the thousand sons were no magpie hoarders" .... but they will be when some of them become Blood Ravens

I simply love the atmosphere you apply to WH40K , great writing and presentation.

I enjoyed that, and it was an hour well spent. Learned quite a bit, and I thought I knew The Thousand Sons quite well.

In order to report this, Oculus must have the inquisitor who tried to stop him locked away in the basement. Not bad. Another inquisitor might give him a promotion.

Perfect time ! I am building a new Thousand Sons légion !! Thank you very much Iterator !! May the Emperor bless you and your work

The Thousand Sons should have been made aware of the dangers of Chsos and trained in the defense against it. The Flesh Change could only be the result of Warp corruption. A Legion warded at the genetic level would not have succumbed.

To our humble educator, Oculus Imperia of the Logos Historica Verita, will their be a thousands sons tactics and structure next? Also, would you please do a video on our cousins of the XIII Ultramarines origins and history and tactics and structure at some point? Even though they have been memed to heck, I still think they are a cool legion/chapter.

I really, truly hope we see a redemption and reforming of the shards, of the Crimson King. I want some non-heretical egyptian space wizards!

In much wisdom is much grief. For he who increaseth knowledge increaseth sorrow.

Love your work so much! Also 45:15 "kingson crim"

Magnus did several things wrong, but doing whatever it took to save his genesons wasn’t one of them.

Hey oculus, I know you’ve already done videos on power armor, but I was wondering if you planned to do a video on Terminator armor at some point. It’s what got me into 40K, space marines casually lumbering through torrents of gunfire, wielding miniguns with one arm, punching aliens with powerfists, like, terminator armor is just the damn coolest

"You're not the only one cursed with knowledge..."

I wonder if Leman Russ went into the Eye of Terror partly out of guilt for his dogged(pun intended) eagerness in the betrayal of Magnus. Might be he's looking for some way to restore his brother and the Emperor or he's attuning to his true nature as a warp-creature like Corax has done.

My favourite legion on my birthday. Thank you Oculus ❤️🇨🇦

Is it me, or is our boy getting more melancholic, even nihilistic in their quest to educate us poor, ignorant fools?

Fastest click in the west

Nice I wanted something to listen to before going to sleep

YES. I was so looking forward to this legion

I've been binging your Astartes origins playlist and it has been such a treat to listen to how you have improved as a narrator over the years. Cool stuff man. :)

This channel is criminally underrated. You do amazing work my friend.

By the throne i love the way you write and speak occulus 🙂 so eloquent and engaging

If I recall correctly Magnus got along best with Perturabo, due to their love and appreciation of information.

Magnus is a digrido master and superb warp crocilid wrangler and proud bike rider

Well done, sir. Your videos are one of the things I look forward to most on RU-vid. I hope you get to make more videos in the years to come. Bless you.

First things first I love you Oculus, never stop. That being said, at 45:14 you said "Kingsom Crim" I wouldn't normally point out something that small but it's really funny to me for some reason

Great Video. Suprised how there were no mentions of Ahriman though.

Another most impressive record. These are always among the highlights of my day!

Question, do you OC think and or believe the" Thousand Sons " were supposed to hold the position of the "Grey Knights" ,but the Emperor after awhile said to Himself "meh"!! Due to that the problems of the "flesh change" that could have been removed became a serious problem. Do you think indirectly the supposed deal with the Chaos Gods were quietly kept above board?

Really enjoyed this one. Thousand Sons are such and interesting legion. Thanks and happy new year to you.

This was seriously good , i always love your legion videos 🤟

I have been waiting a long time for this record. And I was not disappointed. Magnificent. Thank you :)

Black Dragon "Look at them with their Flesh Change....lucky us , our gene seed is free of even the slightest mutation."

Another great video and this time about my favourite legion and primach. Keep up the fantastic work!

Perfect way to start a new year! Be you in good health Historitor!

Every time is the perfect time for a new oculus video.

Great video and these Legion ones are my favorite. The amount of time and effort you put in shows.

These videos have made me want to start a HH Thousand sons force

Oh snap!! Many thanks for your diligent study on our behalves, noble Oculus. 🙏🏻🙏🏻🙏🏻

45:14 All hail the Kingsom Krim!

I love your videos, the way you speak makes me feel like I'm actually talking to an embittered, tired Imperial historian. Very immersive and interesting videos, I really feel like I'm a part of the Grimdark universe!

Cracked my screen hitting the “Like” button

Perfect timing, i needed something great after this workday

The Kingson Crim he says.

This is designed to make us sleepy I swear, it is like going to church watching one of these.

I quite adore the Thousand Sons. A Legion based off the twin themes culturally of ancient Egypt and Persia, with its motifs being sorcery and knowledge. And of course it's Terran roots in ancient Achaemenid lands which lending an eventual fate of tradegy, betrayal, and loss. Perhaps in the earliest days of human history the Emperor had been Zoroaster himself, to grant so many boons to the neophyte 15th Legion.

My brain, excited to see another OI video My body when watching it, This guy has a soothing voice time to sleep One of these days I'll learn about the sons

I absolutely love your videos man. Idk if you have considered this or if it's something you're doing intentionally, but this is a fantastic style for portraying lore in an exciting way. Oftentimes people can find lore videos boring and can make it difficult for people to get into an IP. At least in my experience your videos have been a tool for me to get people into the 30k lore. Thanks mate. Keep it up

I just love the perspective you take in telling you stories in Warhammer 40k.

Ty for the great quality content yet again!!

Ah, the Blood Rave... I mean, the Thousand Sons. My favorites!

Well added Fury of Magnus and Burning of Prospero to my read list. Great video.

I am genuinely happy that all of you are genuinely happy here as the Historator gives unto the Imperium of Man yet another treasure.

Damn, your voice, your music... This is some grade A story book-like content to fall asleep to ❤

As an older man, a high lord of Terra sits watching an opera in high gothic a far younger friend, an inquisition member, freshly minted but battle tested on more than one mission walks into his both "AH, yes young man sit a moment. He dismisses his aids as the sit back a moment and both form their thoughts the old man speaks. "Have you ever heard the tragedy of Horus Lupacau?" The young inquisition looks puzzled a moment and answers "no" candidly. "I thought not, it not a tale the inqiusitorious would tell."

"The Thousand Sons were no magpie hoarders of lore."- Me hearing that line, "Hmm yes, Blood Rave......stupid brain."

hell yeah been waiting for this one!

Perfect way to start my Friday! Great work as always. Keep up the amazing work!

I liked the video and narrative, thank you. Good job!

I have to say I miss zegram's voice as Magnus

Well narrated!!

I definitely love the concept of the Sons, one of my many Traitor legions I want to put time and effort into

I love the thousand sons there my favourite legion and faction in 40k. I've always thought that they should have been the most powerful legion but writers said no

At last he is back.So missed this voice.

Thank you for another excellent video, I do wish that your audio was available as a podcast version though.

The great tradgedy of The 1,000 Sons is not that those with a vision for a better world were brought low by those who were jealous, ignorant and short-sighted. It is that those with a vision for a better world were gifted the power to make that world manifest but withheld from the use of that power.

Absolutely fantastic video.

Friday night and a new Oculus video. Couldn't have asked for more.

Another lovely entry! Enjoyed every last minute of this!

Since I devoured your knowledge many cycles ago as it seems now to my people mind quite possibly due to aesthetics or possibly just not proper upkeep I always forget to add you in my big collaborator wish list but to have you and ab Prince and the others together retelling the tales would be such such a pleasure if that could even be afforded in this damn damn dark age

Very jealous when my friends legion gets an hour long video and mine only get 10 minutes :D Great job! 😀

I love the notion of veterans who played as far back as third edition! I started with Rogue Trader, played second when it came out and had stopped before there was a third! Just coming back to the lore now and boy, has it changed! 😂

_They were no Magpies..._ You know, some of us aren't ready to give that up, no matter what GW thinks.

0:15 We are some of us, cursed with knowledge.... Aight Thanos!

he has released the video

I was wondering when you'd get around to the Thousand Sons. 58 minutes? This is going to be good.

Now this is a way to open a new full year of lore.

This is one of your best yet, keep being badass

I'm sorry, but I still can't call the Thousand Sons, and Magnus, the villains. I still love them all, as much as I love the Ultramarines.

I could listen to you read and the storys you tell all day. you should do audio book readings as well

Still loving your delivery, keep up the great work!

Excellent video. One of the most interesting legions & one of the biggest tragedies of the Heresy.

@45:13 Kingson Crim :'D

58 minutes! Yes. Please.
