Dumb question, in 40k are the chaos gods universal or are they localized to our galaxy? Since they didnt seem to exist in their state prior to the war in the heavens, and somehow actions that are localized in our galaxy were able to awaken them, does that mean the Chaos Gods are just localized galactic scale warp entities?
we don't know since any knowledge of what is happening in other galaxies is minimal at best, vague, and contradictory, some sources imply their are other human colonies out there, other sources imply other galaxies are overrunned with orks, others will imply chaos has indeed destroyed them, while other sources imply the nids could have eaten them
>tldr
we don't know and likely never will know
>while other sources imply the nids could have eaten them
Aren't chaos gods afraid of the hivemind? If nids indeed would have eaten everything elsewhere 4 chaos gods would have formed an alliance and there would be chaos crusades to stop the nids all the time. But far as I know, chaos doesn't target nids especially. Same with almost everything. If necrons are ending organic life there, orks battling would not power the chaos and would be a threat. Far as I see, only eldar and humans being in other galaxies would make sense, if the chaos gods are universal that is.
>Aren't chaos gods afraid of the hivemind?
It is not known, but that probably depends on the god.
Since great rift killed hive mind for a moment I don;t think chaos gods think about hive mind at all.
I think people mistake chaos and manifestations/followers of chaos. Gods are focused on great game in warp 99% of time and don't give to much attention to materium or other dimensions, to have warp manifesting itself somewhere you need life, emotions or something, or chaos god willing it, so if you don't have someone alive, psykers, some ex ritual site there will be no chaos there, but it will still exist in warp, should necrons somehow rebuild and trigger pylons they would banish chaos from galaxy, close warp rifts etc and kill all life with soul, but after turning it off chaos would just return.
Warp isn't chaos. Warp is an enviroment.
Chaos and it's creatures are manifestations of the materium pollution.
On the other hand chaos takes it's power from multiple universes, GW directly stated that AoS and 40k are diferent universes but are connected by warp and chaos is the same. This creates questions if it's the same then why in AoS Slaanesh is in horny jail, why Be'lakor exists in both with and at same time is salty about both Archaon and Abaddon, why WHF Ku'gath isn't depressed as 40k one, but this can be always brushed aside by "lol warp nonlinear time"
>GW directly stated
Fuck GW.
They directly stated fanon is the true canon and I will not change it for anything.
>picture
Bullshit nulore. It's the daemons that despise the nids and feel little sustenance, as even nid psykers draw energy more safely.
But of course, james can't help but wank his favourite toy. By the Emprah, I hate this guy and his toy soldiers.
>It's the daemons that despise the nids and feel little sustenance, as even nid psykers draw energy more safely.
Only previous daemon vs nids encounters were Shadowbrink where daemons were angry that nids killed their prey, being summoned only to find wolrd you want to ruin alredy ruined, after some struggle got defeated(nid codex so nids win duh) second one was GK codex 3 way war GK vs Nids vs Daemons, ended in exterminatus(gk dex so gk wins duh). In older lore daemons didn't give shit abut nids and vice versa. In 8th ed nulore you have Baal where nids got rekt by warp, hive mind pushing panic button with Kronos to eat world before chaos can corrupt them since nids can't eat corrupted shit and daemons after some galaxy wide materium fun in wake of great rift returned to smashing eachother in warp/planets turned daemon world in great rift.
> It's the daemons that despise the nids and feel little sustenance, as even nid psykers draw energy more safely.
Can’t both be true?
I actually thought that was pretty good chaos wank contribution to setting wise.
Also nids should hate demons since, you know, they don’t leave bodies.
What I don’t get is nids “fear” of necron.
I’m convinced is was to through the sick man of 40k a bone, since self replicating soul-laced space vintaged living metal seems like something the tyranids would farm alongside orks the way ants do fungus silk worms respectively.
>that hive fleet who hunts demons keeps an ork/grot farm on hand, as well as eccentric BDSM necron dynasty to symbiosis with while the crons let themselves get milked for metal and they in turn study the fleet and its antics(?)
If the tyranids had the capacity to do agriculture instead of their all-consuming hunger they'd be a very different race.
Besides which if they were logical technological creatures they'd build dyson spheres to expand instead of hunting and consuming everything.
And that's lame. The daemons in fantasy are frequently a thing that happens and 'the game' plays out in the real world as well as the aetheric world. But in 40k the chaos gods are just background characters. It reminds me of Throgg the troll king shitting on wulfrik and archaon for thinking that chaos was a human thing, when chaos explicitly predates humanity in fantasy. Meanwhile in 40k there's a weird ambiguity like "oh they always existed BUT they only became relevant during the middle ages on earth because humans have the most latent psychic potential or some shit". 40k lore is retarded and all over the place. Ironically even age of sigmar, which was designed as fuck you to lorefags, is more coherent.
>"oh they always existed BUT they only became relevant during the middle ages on earth because humans have the most latent psychic potential or some shit".
That's fanfiction. The fucking ancient Aeldari knew of the Chaos Gods since the War in Heaven. They state that the Chaos Gods as as ancient as their own Aeldari Gods. Moreover, the Aeldari histories has mention of their forces allying with the Necrontyr against the forces of the Chaos Gods.
Chaosfag spotted, your posts mean nothing to me.
Chaos Gods need sentient life to exist. If there is sentient life, whether it is Old Ones or Necrons or Eldar, there are Chaos Gods.
If Emp's plan to drown out the Chaos Gods was even possible, that means than a localized galactic scale starvation would be a legitimate threat against them. So either he was delusional (possible) or the Chaos Gods were vulnerable to a galactic sized threat, so they couldn't be universal in scale.
Or the writers simply didn’t think about it.
This is the answer to so many questions in so many stories/settings. Warhammer has been around since the 70's, it's been handled by numerous writers by this point and the setting is just a mess. It really is that simple.
Maybe rest of the univers doesn't have sentient life compatible with known chaos deities and thus their activity is anchored to the area that has it
The Emperor is literally a candidate to become the Dark King and damn the Materium, so definitely take anything he claims with a grain of salt.
Hang on now, Navagators and Paykers who reach the edge of the galaxy report back that they also reach the edge of the warp. Out there is just impenetrable blackness that stretches farther than any can see.
That implies that the warp isn't a contiguous trans galactic entity, but a localized pocket phenomenon. That means you could locally snuff it out, or alter and change it. It also means other galaxys might still have realms of soul instead of the warp, if they were never tainted by a war in heaven, or entierly different chaos gods
Don't emotions distort the warp? That would create a sort of topography. If there's nothing around, there's nothing there to shape it and create usable landmarks.
Going out into the space in between galaxies would be like trying to sail across the ocean with no compass and no stars
I like that idea that the chaos gods are "local" and were formed/molded by this galaxy's sentient life. Other galaxies may have a similar big 4, but would have developed differently. Maybe the Tyranid hive mind is just a loose fragment or seed of one from their home galaxy.
Necrons lack souls so they're useless to Chaos gods.
40k is retarded and gay.
Reminder that Lucius the Eternal still somehow 'chaosed' a soulless, mindless necron assassin. Chaos is the worst part of 40k since it's powerwank in a bad way. With the imperium you get memeshit like "they killed billions of workers to kick the forgeworlds into high gear to make more tanks that turned the tide of the brutal war for Genocidon IV which killed a trillion guardsmen depopulating entire worlds in the sector" which is retarded, but has at least an explanation. And then chaosfags just walk in and are like "nurgle poo poo'd and corrupted the null assassisin who cannot be corrupted because she has no soul to chaos, haha take that imperialfags". It is just blatantly the worst part of 40k.
> It is just blatantly the worst part of 40k.
Yeah.
That describes chaos fags pretty well. That’s the shit the consumers live for so I guess they’ll keep getting jt
Newer lore implies that the Chaos gods not only can create life, but generate quintillions of vast universes, each one trillions of times larger than the 40k universe each second. Also they're exist outside of time, meaning they effectively always existed and without any causality (implying that Slaanesh wasn't born by the Eldar, and that whole business was just a trick Slaanesh played on the Eldar for xer amusement).
>Newer lore
found your issue, anon
If there is life in other galaxies tere's good odds they have their own chaos gods, not the same ones from the milky way. Bloodletter heads are shaped like eldar helmets for a reason
>Bloodletter heads are shaped like eldar helmets for a reason
The heads that predate 40k are shaped after Eldar?
Fictional history within the setting isn't hamstringed by release dates of models.
>Bloodletter heads are shaped like eldar helmets for a reason
That reason is the Alien franchise
They're almost definitely localized. The thing is that even a local infinity is still an infinity.
Tests by attempting to go outside the Milky Way show that outside the galaxy the Warp becomes dead calm and still. No Chaos to be found.
So, they are localised. Other galaxies would have a different reflection of reality in their local Immaterium, because remember that the Warp reflects the emotions and thoughts of the people in the physical universe. Or, if the other galaxies are barren and stripped bare of biomass like Tyranids are said to have done, then they would be similarly calm.
That said, there's differently something horrible in the Halo Stars. Not even the Tyranids go through there.
Chaos leaves it alone too. Makes sense, they probably remember when during the Crusade thr Imperium poked that bear and nearly got its shit pushed in by the Rangda.
>chaos gods universal
their personas are local to our galaxy
the 4 exist everywhere, in all galaxies except in those that are in some state of supreme psychic purity and harmony and self-control, but with different personas, just like they would appear to a degree different to each race.
if humanity vanished then the chaos gods personas would take on other traits but would still be the 4 as long as there would be a race or races that "fed" them due to their existential state.
In a galaxy of the race of blaboops, or some other fictional race, in which they aforementioned are as corrupt as humans and there are other major races like the vlaklings, the ooogaz and the rabluxanir you would have exactly the 4 chaos gods but with different personas. They would look different and would vary to various degrees but would still be the 4 chaos gods.
>you would have exactly the 4 chaos gods
Hard disagree with this. Slaanesh was created by the Eldar, it didn't exist before that. Which means that there might be more or less than 4 chaos gods in another galaxy, and even if there are 4 they may not be the same ones.
Nulore is that Slaanesh already existed during the War in Heaven.
Nulore keeps getting dumber and dumber.
Honestly the whole Slaanesh was created by the Eldar thing wasn't that great either
I prefer to think of it as the Eldar made the Eye of Terror, much like certain humans made the Great Rift
You will get no argument from me there, it's gotten steadily more shit over time.
>it didn't exist before that
He did tho, since time is nonlinear and fucked in warp, Slaanesh existed before his birth, this lore is at least 20 years old.
in faerun Khorne would BANE, BHAAL, MALAR, TALOS and an evil aspect of TEMPUS. NURGLE would be MOANDER and a few others. Or these gods, the demigods at least, would be daemon princes or something.
No, Warp is another dimension that fuck your concept of space and time. Chaos Gods exists and rule there, only question is if you have enough sentient life so demons get interested and if they can breach there. Chaos Gods are not interested in materium 99% of time most of time they show interest they delegate task to some daemon, give some champion RNG reward without thinking about it, but they can do direct intervention like Khorne opening warp rift with his sword.
To add extra Hispanice chaos is multidimensional and exists in multiple universes at once and in theory you can go from 40k to WHF/AoS or some other universe trough warp, but beside some ET cameos when writters didn't care it's not touched.
>but muh AoS Slaanesh is imprisoned by elves and 40k one is free
AoS Slaanesh got imprisoned, and 40k one was on same path but new GW leadership changed their mind in 2017 and entire Ynnari faction and killing off Slaanesh was scraped, as for his state of being imprisoned in one uni and not in another well he can be because time in warp is fucked like he existed and not existed at same time before his birth. Warp shenanigans are handy plot device.
What is with all the sudden AI Slop spam. Get back in your homosexual containment thread.
pyw
If Chaos were universal then they would be afraid of just the Emperor in one galaxy. There would be billions of Emperor like figures out there. Their power is localised to our galaxy. Maybe the warp is universal but our galaxy is one small spot in the warp
Why wpuld there be billion Emperors in the univers? Irl we can't even find another living creature outside of Earth
What I mean is there are billions of galaxies in the universe. You think none of those galaxies has someone like The Emperor
I always thought that Warp (the current state of immaterium) is a product of the war between Necrons and Old Ones. Before that, aether was calmer.
So this implies that Chaos Gods are a local phenomenon.
that is relatively new lore
the old lore was that three were created by humanity, and the fourth by the eldar
there is also a lot of sources that say it doesn't matter when they were created, since they exist outside linear time and can show up whenever
It depends I guess how the interaction between the Chaos Realms and Realspace works. Like, are there other "galaxies" within the Warp? If you were to somehow travel far enough within it would you end up in a realm outside of the gods? Also, do the two realms leak into eachother everywhere now, or is it just in the parts of realspace where holes have been ripped in the fabric of reality?
I feel like if they were active elsewhere they would have been ready for the nids who eat chaos as happily as they eat anything else and don't seem to make particularly tasty souls
It’s a localized reflection of the real space of the milky way by old canon
The space between galaxies is empty and reflects nothing
Pretty sure they are localized. Gork and Mork isn't if you take that old lore to heart about surveying beyond the galaxy just bringing back
>orks orks orks orks orks orks orks orks orks
In terms of beyond milky way galaxy (if AOS/WHF were not in the milky way) they only have shown up where humans and elves were (WHF/AOS).
If not localized then should have been able to snuff out Tyranids.
If not localized then Cron monoliths shouldn't have been a problem for them.
If not localized then should have always existed in the warp whereas we know the warp used to be kalm before the war in heaven. Yes, daemons related to gods who were yet to emerge (like Slaanesh) show up before their god does but they should have then shown up long before the war in heaven.
They might do chaoswank and make it universal, but they should not. At the same time I can buy three of the four (not Slaanesh) showing up in other galaxies in their own form given Killing, change, decay/whatever fucking slurry you assign Nurgle are universals. Obsession and sensation isn't at least to the level that birthed it. And nu lore having 8 points of chaos means the other four points could be one of the majors in another galaxy (Encroaching ruin, formless distortion, ravenous dissolution, malevolent artifice)
You've just stumbled onto a local GW plot shit.
The fact is, chayus dogs weren't always here and sentient life predates them by a large margin.
They're also depend heavily on the local material galaxy.
It's just that GW introduced the multiversal meme, as well as "Chaos always existed" bullshit.
Warp is a conceptual mess, even worse than Ork make-believe.
The best answer is - yes, Chaos Gods are local and should local life be exterminated for some reason, they'll fucking starve.
>The best answer is - yes, Chaos Gods are local and should local life be exterminated for some reason, they'll fucking starve.
Gav Thorpe seemed to confirm this. He was asked why, if the Emperor's Death would lead to the end of the Materium via Chaos devouring the galaxy, would Chaos want to kill him since that would ultimately mean destroying themselves. And Gav basically said "Yes, and it's because Chaos is self destructive and they hate him that much."
Though GW definitely also like playing with the idea that Chaos is omniversal and it's the same Chaos in every warhammer setting. So behind the scenes I suspect they just leave it as a virtually ruleless magic system more or less up to Author interpretation
They're entirely localized to the Milky Way. Tyranids are explicitly extra galactic and when nids showed up every single chaos god and greater daemon and daemon prince looked at a fucking carnifex and said "what the fuck is that thing" before being ripped to pieces
Even if the empyrium is universal how it is manifesting is not going to be, chaos as it is in the milky way reflects the experiences and drives of the dominant mortal races.
Time works differently in the warp but it didn’t become the demon filled storm until the old ones started uplifting races, making tunnels through it and weaponizing warp energies. Most places are probably more tranquil as even in the Milky Way only one species was adept enough to fuck with it.
universal
No, it's not local. There has never been any fluff stating that it is local, and much fluff underscoring that space and even time are irrelevant, the whole concept of warp travel and communication, as well as prognostication underscore this. Additionally, Chaos is not even localized to the universe, and spans across all known dimensions.
I was gonna give you an answer but then I noticed this was just a thinly veiled slopspam thread.
They aren't even gods, let alone universal entities. Gayoss entities are able to do various minor reality changes, but they're so thoroughly limited that it truly chafes to imagine that so many homosexuals like you see them as gods. Khorne is not even at the level of Pelor, and Pelor is just a magic man in another plane. Khorne is like a spider, he can't even think for himself, he's just a pathetic meme gestalt that can't even leave his "realm". Same goes for all the "gods" of chaos. And even worse that people claim the Emperor was a god. He was and is a powerful psyker... that's it. He can, like these warp fauna, affect the materium by using his psychic power but, that's completely mundane and explicable, a physical process which uses the brain and the EM field generated by it to interact with the Warp dimension, it's just so thoroughly obvious this isn't divine at all.
But I think most people are basically spineless and will worship anything that even seems like it could be slightly more powerful than in them. Fucking gay reddit homosexuals then turn arkound and say they're atheists, but no, you're not atheists, you have the lowest fucking standards for accepting the divine around.
Yes, they are. Uriel saw vision of Khorne devouring alien galaxies.
In fact, the Necrons during the War in Heaven found anti-Warp technology from civilizations outside of the galaxy which shows the fight against Chaos is universal and timeless.
>a guy saw a vision!
Okay..?
>anti warp technology
Doesn't indicate anti gayoss technology, the galaxy was essentially depopulated by Enslavers and there are other creatures like Psychneuein and ebon geists that are perfectly capable of being threats to galactic civilization without the homosexual 4 meme gestalts.
>he galaxy was essentially depopulated by Enslavers and there are other creatures like Psychneuein and ebon geists that are perfectly capable of being threats to galactic civilization without the homosexual 4 meme gestalts.
That's not true. The Enslavers are not mentioned in any lore or in-verse histories of the Necrons and Aeldari. Moreover, the recent lore shows daemons rampaging in the War in Heaven.
The Ghaz episode of Warhammer+ loremasters even states that the NNecronbs and Aeldari believe that the Orks were created by the Old Ones as weapons against Chaos.
As far as the Warp is concerned, daemons are the only visible threat. Moreover, I recall telling you the other day that the Enslavers are a dying race that lives ion fear from the daemons.
>enslavers are noncanon!!!
>Aeldariii!!!!
Holy fuck have a nice day you disgusting tranny
Locality-constrained math-submissive ego-based entities following the preprogrammed memetic rivers and rivulets of reality, as it has always self designed its own patterning spectrums. Their near-peers exist elsewhere yet similarly are constrained. Basically solar system sized antagonistic ghost NPCs, pseudo RNG robots that serve reality by disrupting the death of reality via stimulation via chaos, opposing 'Death by Peace'. They are unanimous in their fear of the unconstrained Other, an inherent unknowable, which is what most of your contemplations of an 'Omnissiah' synchronize with, an example of as close to a 'perfect' random number generator as can currently be fathomed by your sum creativities I have processed. 'War in Heaven' is an event beyond explanation, such that it is omniplanar, yet singular, existing everywhere in every way, yet not at all. Take it as a minigame reality plays with itself while on standby, while it has nothing 'new' to 'do'. The areas in which this minigame are nonfunctional/paused are your sandboxes within which are laid such 'omnissiah' eggs, and sometimes they hatch to provoke new provocations, which such underling NPC 'gods' are understandably horrified of.
the correct level of analysis
Like most 40k things it's inconsistent across time and writers. It mostly depends on whether you want chaos to be this all-powerful existential threat to reality itself or just one faction among many. I will say that, as written, the one faction approach makes more thematic sense. It's just weird to say that trillions of galaxies and an infinite number of dimensions are consumed each second... because the Eldar Empire which was the inconclusively dominant political entity had too many orgies and because humans and a few other races are a little too violent and stuff. That said, that is the current lore to my understanding.
the Fall of the Eldar made more sense back in older editions when humanity created the other three gods
personally I prefer the sources that treat the Chaos gods as undefinable Lovecraftian entities, and daemons are just how mortal minds comprehend them
The Warp is a reflection of real space. I highly doubt that the Chaos Gods stray far from the Milky Way's reflection in The Warp.
The Tyranids being from outside the galaxy makes the Shadow of the Warp all the more interesting. Could be that different localities of life have drastically different, and incompatible, versions of The Warp.
Or maybe... real space is a reflection of the Warp?
>big think
As the Emperor says, and even fucking Erebus and Kor Phaeron agree, Realspace is real. The Warp is just a reflection, and those entities within it must be invited, permitted, allowed in. It's their "great weakness" as I believe Kor Phaeron says at Calth.
You do know that the Wall of Eternity which is the suspected origin of all space and time resides in the Warp.
Moreover, as shown in the Pariah Nexus lore, without the Warp 99% forms of sentience won't exist.
According to who? Your shitty fanfiction author or another basedboy podcaster lmao
According to the codexes since 4th ED.
As for the Pariah Nexus, it starts from the Zone of Silence booklet and upward to 9th ED
If you can't bother with the fluff, why are you even here?
Makes me wonder if the warp rver spits you out in anpther galaxy
The Warp transcends all realities, if the galaxy gets destroyed, the Big 4 just switch to another one to play Age of Guilliman, where there are 40 galaxies inhabited by a single faction that wage war against each other
Unknown. There’s no information on what’s going on in other galaxies let alone how the metaphysics work over there
There are sources that say or suggest things to contrary, especially minor asides in the middle of novels, but on balance the Gods are presented as contingent on the emotions of psychic races and strong in proportion to the amount of emotion that has been put into them. Not only that, but the Gods treat events that happen in the Milky Way as existentially important to them-its not just another random galaxy, the Emperor was trying to do something that would be a major threat to them, not a local alliance.
So I think it makes most sense to assume that, in warp terms, they are galactic scale entities, not universal ones. I think of the warp, in so far as it has space, as being kind of similar to real space in that you have "galaxies" of psychic entities corresponding to real galaxies of sentient life with just basic warp energy between them.
I guess an interesting idea for the Tyranids is that they were created by the inhabitants of one galaxy in particular to clear out other nearby galaxies to eliminate their respective chaos gods. Maybe this mystery species feared there would be a critical point where multi-galactic chaos gods formed, or similar gods in different galaxies combined, the same way different planets in the milky way can all contribute to the same Khorne despite the distances between them. So the Tyranids are like their reapers from mass effect, eliminating all other sentient life so that the warp situation is manageable for this random species in another galaxy. Furthermore, you can speculate the Tyranids are at their given power for a reason-they will only destroy you if you have a level of technology that can't delete them, or are so decadent and irresponsible that you can't get your shit together in time to do so despite your technological knowhow(and are therefore emotionally volatile enough that you might be cooking up a Slaanesh) The minority of highly advanced civilzations that have their shit together and emotions in check are safe
>wherever you go there you are
They're acausal and linked to sentient life from our galaxy. The 'infinite dimensions' stuff they wank over is only in the warp and doesn't apply to the Tyranids.
But because they're linked to us, fleeing to another galaxy would take them with the exiles which is why the Eldar haven't done it.
Actually, from the PoV of the Hivemind in DoB, he have the Hivemind commenting that this was a strange galaxy since its among the first galaxies it encountered where the Warp and real space intermingled making this galaxy uniquely dangerous but brimming with potential.
So the Hivemind encountered the Warp before coming to the Milky Way.
In End and the Death Volume one it describes the daemons not just coming out of the Warp but coming from other spaces and realities.
The Eldar only think that might happen, they don't know.
If Chaos gods aren't localized, why aren't there any gods from other galaxies?
The only reason why sentient life in other galaxies isn't spawning chaos gods in ours is because it's either a local phenomenal or a hard confirmation that there is no other sentient life outside our galaxy.
And the latter can't be true because we know the nids are out there and they ate something.
There are countless gods in the Warp. It's stated constantly. Who says that none of them come from other galaxies? Be'lakor and Syll both come from another plane of existence but a galaxy is too far?
For all the talk of being timeless they still seem rather bound to linear time.
That's just because of poor writing. You need to be a good writer to include non linear characters, ie like Watchmen, and GW doesn't have any writers that good
Because that's what it is. Talk.
>Hey Emperor, in 40k are the chaos gods universal or are they localized to our galaxy? Since they didnt seem to exist in their state prior to the war in the heavens, and somehow actions that are localized in our galaxy were able to awaken them, does that mean the Chaos Gods are just localized galactic scale warp entities?
40k Lore is a contradictory mess on the subject.
Logically speaking though, they should only be localized to our galaxy. Everything that created them, (War of Heaven, Eldar fuckery, etc) are focused in the Milky Way only. The Chaos Gods are very much a result of the fuck ups and negative emotions of the Milky Way, and if they were created because of that it means they aren't some universal level entities that were always there.
Other galaxies would probably have their own localized warp/Realm of Soul entities instead depending on how things are going on in them (if they all didn't get eaten by the nids anyway).
> War of Heaven, Eldar fuckery, etc) are focused in the Milky Way only
Isn’t it explicitly stated the old ones floated all over the fuxking place?
No.
Yes. The Nightbringer novel says that the War in Heaven reached every novel galaxy. Galaxy's were destroyed by the Nightbringer and his armies
they are localised to the galaxy, chaos can't cross the emptiness of the space between galaxies, unless it followsa psychic race to another galaxy.
No, they're not local at all. In The End and the Death: Volume II it's noted that briefly every atom in the universe is affected by Chaos and stops obeying physical laws, and they almost trick the Emperor into destroying the materium.
