So I was trying to think up fluff for a traitor guard regiment and I got to thinking about regiments raised in the Eye. Would the various Legions' Daemon Worlds have regular human populations like Hell's Iris? Would some? Would some not?

Hope this helps some. Both are from Lexicanum.

The Plague Planet is a world where disease is the norm and miasmic clouds bring contagion and death. Its diseased inhabitants pray to Nurgle for relief from their constant agony. Some of them are favored and become his Champions, and then fight among themselves for mastery and the chance to become Daemon Princes themselves.

Mortarion has shaped the planet much as his homeworld, Barbarus. Its citizens cower in tiny villages, serving their supreme masters who reside in mighty fortress citadels far above all of them.

Yeah, reading the Sicarus fluff I kind of got the impression that they had humans living in a constant state of religious oppression. Kind of like a twisted version of Terra.

This has always bothered me, and I hope it gets retconned at some point.

Mortarion's primary reason to betraying the Emperor (note, not referring to his fall to Chaos), was that his experience on Barbarus instilled in him a fierce hatred of tyrants. He led the uprising against the Xenos kings that oppressed the humans on Barbarus, and iirc the xenos were also psykers, which is why he hates psykers and sorcery.

So... it doesn't really make sense that a guy who flies into a frothing rage by the mere whisper of "slavery" or "tyranny" would bend his realty-warping powers toward creating a planet where the entire population are... slaves.

Yea, Mortarion's a huge hypocrite right now. Though he was kinda a dumbass the way he fell in the first place, succombing to Nurgle just for the sake of his own life.

However, I think this might be on purpose. Because Typhus, who's an actual sincere Nurgle believer, actually looks down on Mortarion for being content to sit around on his daemon planet and is sickened by Mortarion's sentimentality in shaping it like Barbarous even as of the latest Typhus book in that character encyclopedia series ("Lords of the 40th Millenium" or something). I dunno if GW intended for Mortarion to look like a lazy hypocritical dumbass, but at least the guys who manage Typhus' fluff are sorta running with it.

I think it fits. Chaos turned him into what he despises the most. Sure he still thinks of himself as a great humanitarian leader, but he is a monster by his own moral system. This amuses the powers of Chaos.

And, as TiamatRoar said, it was Typhus the mind behind the turning. And he was a sorcerer. And he entered the legion in spite of Mortarion hating sorcerers, and became his right hand.

I really miss a book about Mortarion. We know nearly nothing about him. We don´t even know who or what his foster father was. In "Flight of the Eisenstein" he was seen as distant and unfathomable by his own soldiers, and later he is typically depicted as a moustache-twirling 1-dimensional evil guy without much coherence from writer to writer.

To the OP:
If you are searching for human chaos armies, there are some good examples here. They are not from the Eye though:

Ben Counter has a thing for creating unique Lost and the Damned armies: Grey Knights, the Bleeding Chalice and Crimson Tears are about marines, but contain brief (yet sweet) descriptions of chaos cults. However, Daemon World: describes a world in the eye. I think this could be the best background reference for your army.
An old book, Eye of Terror, by Barrington Bayley, gives a lot of information about the people near and inside the eye, and includes a massive invasion from inside the eye. Unfortunately, there is few information about the armies.

Another option would be using the Eye of Terror Codex, that gives rules for traitor guard (The Lost and the Damned). It is mostly rules, few background. Some armies are:
However, there is mostly information about forces from outside (yet near) the eye that turned traitor recently.

Finally, if you have time and patience, you can search for more stuff here: http://wh40k.lexicanum.com/wiki/Category:Chaos_Cults_and_Mutants
here http://wh40k.lexicanum.com/wiki/The_Lost_and_the_Damned
or here http://wh40k.lexicanum.com/wiki/Traitor_Guard


Hope that helps!

I think some daemon worlds might have a human population, there is a rendition of a daemon world in one of the Grey Knights novels and the planet is essentially a giant Colosseum full of crazy chaos worshiping freaks . But the majority of human populations on Daemon worlds are probably slaves and instead of forests these worlds most likely have miles of stakes with torture victims attached to them :p But anyway there is zero chance of people living normal lives on Daemon worlds,Raising families etc, and traitor guard regiments probably aren't born and raised on Daemon worlds at all and the soldiers would have been born on Imperial worlds and form traitor guard regiments when they become... traitor as it would be virtually impossible for a mortal human to live to an age fit for military service on a Daemon world.

There's several daemon worlds in the Black Crusade RPG books as well.

And there is a book from BL called Daemon World. They are effectively specialised and mutable deathworlds. Only the strong and ruthless survive.

I mean, there is absolutely nothing subtle or insidious or ironic about what Mortarion is doing. He hates tyrants and slavery, he created a daemon world and instilled slavery and tyranny. He never considered himself to be a Humanitarian in the first place. He doesn't care about butchering people in their thousands, and has always been one of the more violent Primarchs. He just hates slavery and tyranny, and rebelled against the Emperor because he felt that the people under His command didn't have a voice. Creating a planet where you purposefully build a caste of people who have no voice is directly anti-thetical to what his beliefs were.

Given the fact that much of a Daemon(Primarch)'s attention is focused on the great game in the warp, and not the material realm, Morty could just be so far gone that instead of equating what he is doing with slavery, but now is on the other side and thinks that his actions are for the best interests of his people.

To be honest, I really don´t know. I would love to see a book about Morty, explaining his motivations and the reasons for his decisions. I still think there is something ironic (or something intended to be ironic) in turning him into a brutal tyrant.

By humanitarian I meant that he was against enslavery, tyranny and the like. He was quite violent, that´s for sure.

The book is Hammer of Daemons. I had forgotten that one.

But I heavily disagree with you. In that very book you see cities, empires, armies, fleets coming from a Daemon World. It is not a "giant Colosseum", there are cities and the character is taken from one to another. BIG cities, with thousands of years of history. The same goes for the Daemon World book.

By the descriptions we have on those worlds they seem to be feudal worlds, but with high technology / magic. There are lots of people rising families and cities and even full armies, able to get out of the eye and attack the Imperium... as you can see in the book you just talked about!

Living on the average world inside the Eye doesn´t seem worse that living on the average imperial world ("the cruellest and most bloody regime imaginable"). The world described in Daemon World is harsh, but still a paradise compared with Krieg or a hive world. And the world described in Hammer of Demons is harsh... seen from the eyes of a slave who is heavily indoctrinated by the enemy, but there were lots and lots of happy people enjoying the games.

Wasn't Torvendis (Daemon world) in the Maelstrom, not the Eye of Terror? Minor niggle but I thought the world's in the Eye are more hellish and less slaved to the laws of physics. The populations on any kind of Chaos world wouldn't even necessarily know that they are Chaos worshippers, they simply have no other point of referrence to suggest that they worship something evil.

The best example was the Pre-Lorgar's coming to Colchis. This was a perfectly functioning world that worshipped old gods that no one seemed to have any idea were evil beings in the Warp. Only a select few like Kor Phaeron and Erebus were wise to the truth. Lorgar's decision to submit to Chaos was based on the sheer volume of world's where the same pattern of belief was found over and over. I actually think this is why the Emperor stamped out religion in general, because far too many societies were unknowingly worshipping chaos and it was too risky to differentiate between religions, so better to erase all memory of any of them. Of course he failed in this regard as thanks to the Word Bearers, a great many worlds were spared because their core beliefs mirrored the old ways of Colchis and Kor Phaeron knew that these worlds (like Davin) would be instrumental in the Horus Heresy.

I'm pretty sure Lorgar's decision to worship the gods was made after direct communion with the gods while on his Pilgrimage.

Yes but it was influenced by the fact that Kor Phaeron was already head of the Chaos based religion on Colchis before the coming of Lorgar. The planet had a huge civil war because Lorgar had visions of the coming of a singular god. After he was shamed at Monarchia, Lorgar laments that he may have wiped out the true religion in place of a false one. Kor Phaeron admits that the old faith is still alive because he has been sparing worlds with similar beliefs to Old Colchis.

I am not sure if he is being hypocritical or not or if it's just a change of outlook, he's attuned to the warp now and a slave himself to Nurgle, i'm sure his opinion on the matter has changed since the Heresy broke out and he has different aims. If he is going to be a slave he might as well enslave others. He still might see himself in a good light, as at least, he is keeping the people on his world .. alive - ish.

Yep, my mistake.
Drakaasi, the daemon world from Hammer of Daemons, is the one inside the eye.
Anyway, both seem to me feudal worlds, closer to Warhammer Fantasy than to 40k.

^This.

I actually think this is why the Emperor stamped out religion in general, because far too many societies were unknowingly worshipping chaos and it was too risky to differentiate between religions, so better to erase all memory of any of them.(...)

I prefer this version: all religions are the same.
That´s a concept brilliantly expressed by anthropologist James Frazer in his book "The Golder Bough", a key text book in anthropology.
http://en.wikipedia.org/wiki/The_Golden_Bough

This book was highly influential in fantasy & sci-fi during the golden age. HP Lovecraft listed it together with fictional books such as the Necronomicon, and Stephen King did the same in some of his short stories. The philosopher Ludwig Wittgenstein was also more or less obsessed with this book.

In short: all cultures and religions of any part of the world are roughly the same. All polytheistic religions have a god of war, a god of death and so on, with monotheism as a progression / simplification of the same concept, sort of trying to see the greater view by assuming the lesser gods were part of something bigger. Magic was seen as a previous state, with science the next step. He specifically tracked down fertility cults that involve the sacrifice of a living god or a king, and made it apparent that there were far too many similarities worldwide. The same rituals, the same concepts, the same tales/legends, over and over again around the world.

I think whoever wrote the "original" version of the Heresy had this in mind. I am not talking about Ward & Co, the current GW´s creative team is... suboptimal. But warhammer´s background is really deep in some points. And this is (I think) one.

In game: all (polytheistic) religions are the same. And the gods they worship are real, parasitic creatures harmful to mankind. The only way to defeat them is to make the people ascend to the next step: science, logic, reason. All religion must disappear, since it feeds the gods. That´s what the Great Crusade was about (as well as conquering the galaxy and reuniting mankind, of course).

Anyway, this is just a pet theory.

About being a slave... a slave of who? Nurgle is an emotion, and his only master.
Using an easier example, a slave of Khorne is someone who has given himself completely to wrath. While it is still slavery, is of a different kind of the normal master-slave relation.... There are no "orders". This is why giving yourself to Khorne is described as a "liberation". (I am not saying they are actually free, it is more of a random musing)

True, various emotions. But all those emotions are built up into a conscious being. Or so various publications lead us to believe, Slaanesh interacts with Marduq in Dark Disciple, all four interact with Talos in Soul Hunter, the Daemons Codex has banishments and hunts.

If Nurgle wants Mortarion to do something, Mortarion is bound to do it, it's the price of immortality. That gift is also a curse, you might have the illusion of free will but you are still tied. He might lead his own plague world but it's all done in the worship of Nurgle.

That's my take anyhoo

Great link da001, have an exhalt.

This was touched upon in one of the Zeitgeist movies as well. How even in Christianity, the same stories with almost the same details are included in world religions throughout history. Almost all being somewhat based on the cycle of day and night, light and dark, good and evil.

This theory on the Emperor's motivation makes a lot of sense. It's already clear from the fluff that the gods are known by multiple names. So it doesn't seem to matter who they offer their worship too, if a person's actions fuel a certain emotion then it will feed the appropriate god in the warp. In the first Soul Drinker's book, there is even a cult who think they worship the Emperor when in reality they are worshipping a Daemon of Tzeentch.

I think one point of confusion on the functionality of Chaos worlds as societies, is that people think Chaos, they think Chaos Marines. I imagine living on a Legion world is a nightmare, where cruel demi-god like beings rule with an Iron fist, 10,000 years of bitterness using their mortals like slaves to wage war apon another, like Medrengard.

World's like Torvendis however, may have had an Astartes presence, but they were too few in number to rule the planet alone, they were simply soldiers in the army of the ruling caste. Plus I imagine mono-god planets are worse to live on as they would focus on one aspect to the extreme. Worshipping the Pantheon however could quite easily fit into a normal, functioning society, although more suited to a slightly backward feudal type economy because advancement and technology would banish away a lot of the need for worship.

Kinda on the same subject, do you think that there are possibly any daemon worlds that may actually be nice to live on? Yeah I get that most of the human populace turns in to the play things of the Chaos Gods/Daemons/Their Champions, but they have to recruit cultists somehow right? I doubt they get lured into joining chaos by the prospects of: getting mutilated and torn limb from limb, succumbing to every pox and disease known to mankind and beyond, being violated in every imaginable way possible (and not the fun violation), or being mutated continuously just to satisfy a Daemon's particular desire for change.

If you read some background about daemon worlds, they are mostly feudal worlds with some magic / high technology items on them. There are nobles, cities, nomads, all sorts of cultures and civilizations. There are also demons in the planet, and if you get near them, you will not be happy. And if the daemons want to do something, they just do it. Even reality obeys them. But most of the time they ignore you, and the chaos champions are few in number. If you are part of the higher part of society, it can be nice.

Another perk is the distorted time. In "Eye of Terror", by Barrington Bayley, a Lord of Change gets what looks like a way out of the Eye. He allies with a Bloodthirster after defeating him in a duel. The duel goes like this: each of them get a world full of worshippers and they distort space to create a single "gate" between them, informing their worshippers that the other people must die. The LoC wins, partly because the Khorne daemon is curious about the way out of the Eye.

So they agree to join forces. The survivors of both civilizations are told to became a single society, the planets merge, and the greater daemons let a single day pass. A single day for them. When they are back, thousands of years have passed in the new planet. They have gone through full technological development and are ready to build a monstruous space fleet far bigger than battlefield Cadia. The greater daemons send the fleet, fail, get frustrated and leave.

During thousands of years, those worlds were left to their own. Humanity prospered on them. Of course, when the greater daemons wanted to do something with them, they did. They own them. But for most of the time they leave them alone.

Chaos Daemons are parasitic entities. They feed on humanity. They need humanity to be strong, to prosper, to be healthy. They need a constant rate of births, they need hope to destroy, civilizations to take down, beliefs to shatter, morals to violate, innocence to corrupt.

For instance, they need innocent people on these planets, the more the better, to grow happy and secure in order to brutally defile them later. That´s how they feed. Killing all humans will kill them too by starvation. (The "human" side of the gods, anyway; xenos can feed them too, but their emotions are different.)

My thoughts exactly.

In the merged world in Eye of Terror, technological advance was allowed with a single, clear purpose. And Change and War joined forces. I think a mono-god planet will have a lot of problems to do what they intended, which is the reason why the Lord of Change asked for help to a GD of another god.

You are welcome, and thank you for this reference to the Zeitgeist series. Didn´t hear of them until now.

Exactly right. This is why the cabal wanted Horus to win the Heresy. A total victory for the traitor legions would have devasted the galaxy and then over the course of a few decades, the full might of the Legions would have turned on each other with no other common enemy to hold them together. With humanity virtually wiped out in the ensuing wars, the Pantheon would not have enough emotion to feed it and would burn themselves out, sparing the surviving galaxy from the forces of Chaos.

I actuall think that in this way, Chaos won the war, they got 10,000 years of endless war, despair, oppression and fear. The Imperium now has to be harsh and oppressive to survive which in turn, breeds dissent and reasons to turn to the dark gods. If you look at the motivations of the Instigator's of the Heresy (Erebus, Kor Phaeron, Typhon etc) then it seems like this was probably their intended outcome all along. The Primarchs in their hubris thought that they were using Chaos as a means to an end to win themselves power. However it was the lower ranks of Astartes that actually benefitted. In 40k it is Abaddon, Typhus, Lucius, Erebus and Kharn, that lead the Chaos forces, fighting an unending war. The Primarchs have been largely taken out of the equation now that the concerns of their mortal followers are mostly behind them. The loss of the Heresy actually created a myriad of opportunities for many Chaos marines to move out of the shadows cast by their Primarchs. I belive unless they retcon it, Typhon basically screws Mortarion into joing Nurgle by purposely trapping the Death Guard fleet in the warp where they begin to fall to the Destroyer plague. Now Mortarion and most of the other Chaos Primarchs may be daemons, but they are trapped on a path that they never wanted to be on. Mortarion hated slavery, Angron wanted to die, Perturabo wanted forgivess, Fulgrim wanted human perfection and Magnus wanted to raise humanity to enlightenment.
All of them have failed in that respect, and now they are all trapped as immortals, distorted mirrors of their old selves, standing for everything they used to despise.

The Chaos champions however have largely got what they wanted, with the exception of maybe Kharn who was also corrupted from his orginal nobility, but most of the others; Fabius, Lucius, Erebus, Typhus, are all free to pursue their own agendas.

On a Chaos world I think this would be a similar case; Individuals would use to Chaos to advance their status or abilities but it would never be beneficial to wipe out all life, as total death is peace, and in peace there is no Chaos.

From Lexicanum:

After the conflict, cultists are often taken back into the Eye of Terror where they either join the damned population of a daemon world or are formed up into a Chaos Warlord's armed forces.

Maybe this could fit in with what the OP is looking for. Cultists could form a fighting force similar to a Guard regiment and use captured vehicles etc. Along the way some actual Guard could turn and increase the force's numbers.

I myself have been wondering about a Slaanesh based Daemon world. I think they would have plenty of Humans actually living on the world since this god is all about sex, drugs, & rock and roll. When they're not fighting, or feasting they must be having orgies that would make an adult fim look tame.

Sex, Drugs and Rock'n'Roll is, like, Slaanesh-lite.

Slaanesh is the god of Perversion. You have to be into some pretty depraved gak to draw the attention of Slaanesh. Just getting your rocks off with some local nubiles of your preferred gender is not going to cut it.

But would Daemon worlds of Slaanesh plausibly have a Human population for any reason (slave, cultist etc.)

Depends on the ruling Daemon really.

Some won't brook any mortals sullying their domains with their presence, some rare few may treat with mortals fairly, others exult in their veneration and fear, others couldn't care less, and so on so forth.

Daemons are beings of chaos, their mindsets, modus operandis, and opinions are very diverse, though the gods impose some order via their general theme.

The Daemon World novel has just such a world as the main setting. There are pleasure cultists, industrial cities, slaves and barbaric tribes in this particular case.
