A deep, deep dive into what the lore says about multiversal nature of the Warp, part 2: Older lore

 In a prior post (available here: https://madministratum.blogspot.com/2025/11/a-deep-deep-dive-into-what-lore-says.html) I surveyed the way in which a multiverse connected by the Warp has featured in recent lore in what could be called the ‘current era’ (post-End Times and start of AoS, and post-Fall of Cadia and Great Rift), including both in the individual lores of 40k and AoS as well as mentions of a connection between the 40k galaxy and the Mortal Realms of Age of Sigmar via the Warp.

Now I will chart some older sources (from 40k and the Horus Heresy books, and WHFB, as well as other GW games too) which also present a multiversal view, with the same Warp and Chaos touching different realities. This is not to claim that all of the old lore is still relevant (or completely relevant), though some bits may be. It is rather to help trace how enduring the concept in question has been, and to help track how it has evolved in implementation over the decades. Indeed, as will be seen, the use of the concept faded out of use for a while before coming back in the lore, before becoming gradually more and more present.

Let’s start with the end of the Warhammer World in Fantasy, where the Chaos gods didn’t see their destruction of the Warhammer world as a particularly big deal:

And so the mortal world fell away into oblivion. The gnawing rift at the heart of Mankind's domain devoured reality.

Slowly it spread at first, but then with the hunger of ravening wildfires.

Invigorated, the polar rifts slipped their ancient bounds and joined their younger sibling in its feast.

The peoples of the World beheld their doom, and screamed in despair.

No two watchers beheld the same vision. Some saw skies riven with fire, some looked upon an ice-cold maelstrom of stars, some saw colossal tentacles and fanged maws that drooled the molten stuff of Chaos. Perhaps the Chaos Gods raised their champions to daemonhood from the battles that raged amongst the flames. It matters little, for the truth of those hopeless wars are lost.

The Oak of Ages was swallowed last of all. Mournful dryad-song echoed under livid skies as Athel Loren perished. With its destruction, the Weave that bound the time and space together thinned and stretched. Twisted by unnatural energies, it dissolved entirely into nothingness.

That terrible act of uncreation might have taken the blink of an eye, or unfold across millennia. The Dark Gods were not fettered by the flow of time, and let it pass unmarked. Already tired of their victory, they turned away from the ruin they have wrought and began the Great Game anew in other worlds and other creations. In doing so, they paid no heed to the tiny speck of light tumbling in the infinite darkness –  the glowing essence of what had once been a man.

Through the storm of nothingness he fell, adrift for aeons upon unseen tides.

Then came a glimmering orb, a fiery world-heart grown cold as the abyss.

Desperate, the figure seized upon the sphere with a grip that could shatter mountains. He stared into the void, and from the darkness, the void stared back.

The figure clung tight, marshalling his faded strength. He reached forth his hand, and a miracle took shape.

And what of tomorrow?

What of tales yet to be told, and the cycle of the stars?

These were truly the End Times.

But they were also the beginning.

Warhammer: Archaon (2014), p. 256.

Which fits with the examples from the first post about Chaos have consumed/destroyed other realities. We of course already saw what Archaon himself did afterwards, which concerned a lot more reality destruction.

That last part, by the way, is describing the origin of how the Mortal Realms of Age of Sigmar came to be – and we will see other examples of reality creation via the Warp in some of the other quotes in this post.

Other relevant passages:

When freed from the righteous restraints imposed by the Imperium, populations will develop psykers more frequently, releasing a growing vortex of psychic energy that tears at the fabric of the multiverse.

Warhammer 40k Core Rulebook 6th ed. (2012), p. 323, and reprinted in Warhammer 40,000 7th Edition Rulebook – Dark Millenium (2014), p. 239.

And:

‘It is incredibly ancient techno-arcana that relies on an understanding of M-theory. Do you possess such an understanding, Baron Roland?’

‘No, but I am a quick study.’

Vril pauses, no doubt trying to think of how he can explain something complex to a man he believes to be mentally subnormal.

'The central conceit is that our visible, four-dimensional universe is restricted to a brane, that is, a membrane, inside a higher dimensional space,' he begins, and already I feel any hope of comprehension fall away. 'A theoretically infinite number of dimensions of potentially infinite scale occupy other branes, which, in effect, means there can be an endless series of alternate realities, intersecting with our own in ways we cannot possibly imagine in any currently posited cosmological model.'

…

'So a brane shield moves us out of the brane in which our known universe exists and into another,' says Anthonis. 'Now is that a pre-existing brane or a newly created one?'

…

Adept Vril has the good grace to sound impressed when he says, 'A simplistic way of interpreting a complex theory, but, in essence, correct. And in answer to your question, the field generator shifts us into the nearest unoccupied brane, one yet to develop its own internal universe. There we reside in splendid isolation. Nothing can interact with us, but nor can we interact with anything beyond the extent of the field until its deactivation returns us to our origin point.

…

After hearing Magos Vril describe how we are kept safe from the tyranids beyond the temple, it is all I can do to keep my eyes from drifting to the disturbing sky I now know is not part of the universe to which I belong.

…

I do not pretend to comprehend the techno-sorcery of a brane shield, but to see it in action is to feel its working on a visceral level.

 Its outer limits are marked by the same undersea-haze, desert-mirage we saw from the outside, with one crucial difference. From the outside, we saw a static image of the forge-temple as it was at the instant of the shield’s activation. From the inside we see the tyranid host, but they are ghosts to us, moving among us as phantoms.

 The beasts are oblivious to us, as insubstantial as mist. They move among us like reflections on still water, separated by an infinitesimal skein of interdimensional membrane.

McNeill, 'Knights of the Imperium' in Servants of the Machine God (2014), pp. 125-26, 130.

And, from Alivia Sureka’s description of the Warp-gate on Molech:

It looked and felt like a solid barrier, but it wasn’t. It was a scab over a hole that should never have been torn open, an impossible object that existed in an infinite number of possible existences. It was neither real nor unreal.

McNeill, Vengeful Spirit (2014), p. 281.

And, one which is a bit ambiguous due to the way the term “realms” can be used, but which, given how it is often used in Warhammer akin to realities/dimensions is worth noting:

Perhaps the Architect of Fate has plans to overthrow the other Chaos Powers, or to extend his dominion over all the mortal realms.

Codex: Chaos Daemons 6th ed. (2013), p. 12.

Note, this is before the Mortal Realms of AoS existed!

And:

It is said that when Khorne first created the Daemon that would become Skulltaker, the Bloodletter immediately chopped the head from the first creature he met - another Bloodletter. So began an existence of decapitation that has spread terror throughout the mortal and immortal universes.

Codex: Chaos Daemons 6th ed. (2013), p. 34 (later reprinted in the 8th ed. Codex, p. 34).

And:

Of all the puzzles in the multiverse, there is but one that escapes Tzeentch's ability to solve - the Well of Eternity.

Codex: Chaos Daemons 6th ed. (2013), p. 42.

And:

Ku'gath is the most eager of Nurgle's Daemons to enter the mortal realms

…

Atop a palanquin loaded with the paraphernalia of a mobile laboratory, Ku’gath is carried across the universes by a mound of straining Nurglings as he searches for the elusive combination of blights and woes that will recreate the perfect disease.

Codex: Chaos Daemons 6th ed. (2013), p. 51, first printed in the 4th ed. Codex in 2008 on p. 48 and later reprinted in the 8th ed. Codex on p. 51.

And:

Time flows strangely within the empyrean. In the scattering of the daemon’s remains, I see patterns. I see shapes and colours. I see echoes of things that are, and futures that were.

I see an old world beyond the next horizon – a world that likely never was, where sorcery blew in the very winds and a self-made god-king was all that stood against the Ruinous Powers.

Mayhap I would find the answer there, if I could find it at all.

Kaldor Draigo: Knight of Titan (2013), p. 12.

Which is very obviously Draigo glimpsing the Warhammer World via the Warp. Calling it an "old world" is a knowing wink towards the Old World (the core focus of the Warhammer Fantasy setting), the god-king is a reference to Sigmar, and the mention of sorcery blowing in the winds is a reference to the Winds of Magic.

And, an example of the Warp possibly being linked to reality creation (at the very least, the Warp is being used to survey possible futures, but the bit about new universes being spawned suggests reality branching into myriad new parallel realities):

Beyond was something even more spectacular, defying rationalisation. Beyond were the constantly shattering planes of existence; the overlapping planes of destiny; the interwoven threads of fate. The present surrounded Thirianna, but just out of reach was the future, and in the darkness behind was the past. Every life, every thought, every movement, every motive, weaving together in a dazzling tapestry of cause and effect. It branched out, splitting and dividing like cells, spawning entire new universes and possibilities with every passing moment. Thus was the skein, and it was beautiful.

And too much.

Too much to see to comprehend, to understand.

Thirianna passed out.

Thorpe, Path of the Eldar (2011), p. 55. Later reprinted in the Path of the Eldar Omnibus (2014).

And a three quotes on which also show how realities can be created from within the Warp (as, indeed, the Mortal Realms of AoS may have been, and is apparently an idea GW Games Developers long held but didn’t really foreground in the lore – as I will cover in a later post):

This was the very essence of the Primordial Creator, the wellspring from which all things came. Nothing was impossible here, for this was the foundry of creation, the origin of all things, past, present and future.

McNeill, A Thousand Sons (2010), p. 177.

And:

Here in the Great Ocean, he could be whatever he wanted to be; nothing was forbidden and anything was possible. Worlds flashed past him as he hurtled through the swelling tides of colour, light and dimensions without name. The roiling chaos of the aether was a playground for titanic forces, where entire universes could be created and destroyed with a random thought. How many trillions of potential lives were birthed and snuffed out just by thinking such things?

McNeill, A Thousand Sons (2010), p. 712.

And:

"Was this always what you wanted?" asked Magnus. "To see me destroyed?"

"Destroyed? Never!" cried the reflections, as though outraged by the suggestion. "You were always to be our first choice, Magnus. Did you know that?"

"First choice for what?"

"To bring about the eternal chaos of destruction and rebirth, the endless succession of making and unmaking that has cycled throughout time and will continue for all eternity. Yes, you were always first, and Horus is a poor second. The Eternal Powers saw great potential in you, but even as we coveted your soul, you grew too strong and caused us to look elsewhere."

...

"I once named myself Choronzon to you, the Dweller in the Abyss and the Daemon of Dispersion, but those are meaningless labels that mortals hang upon me, obsolete the moment they are uttered**. I have existed since the beginning of time and will exist beyond the span of this universe**. Names are irrelevant to me, for I am every name and none. In the inadequate language of your youngling species, you should call me a god."

McNeill, A Thousand Sons (2010), p. 737.

And, back to more general statements:

Blindness may be the price I pay for the God-Emperor's sacred touch, but I see more than you can possibly imagine. I see worlds rolling countless and wondrous beyond, I see colours and sights that would burn your mind to cinders by their merest glimpse. I see...Them, lurking in the spaces between realities, their claws ever scratching to get in, ever wanting. No, it is you who are truly blind, ignorant and imperilled as a helpless child in the blackest night with ravening wolves all around. For they are here, right now around us and you cannot see. In the dark, in the light it matters not... for they see you and they hunger.

— Astropath Plenipotentiary Aldus Col.

Rogue Trader RPG Core Rulebook (2009), p. 154.

Note that daemons are being implied to be lurking in the Warp, between realities.

And a supplement for Warhammer Fantasy Roleplay 3rd ed.:

Despite the impossible heights to which Slaanesh's servants soar, all but the smallest fraction inevitably come plummeting back down to earth to be dashed against the jagged rocks of their own sins. The power of Chaos is the most seductive, powerful, and addictive drug ever imbibed by mortal souls and, like all drugs, the addicted are doomed as soon as the first taste passes their lips. Those who dedicate their souls to Slaanesh seek to draw power from their pact, power to drive them to extremes they would never otherwise experience, but the price is terrible indeed. Ultimately, the adherents experience all there is to experience, break every taboo, exceed every mortal limitation, and impose every form of suffering the mortal mind and body can endure; all that remains is a soulless husk driven by the hollow desires of one who has seen all and knows there is nothing left to see. For a time, the universe, indeed the multiverse, was a realm of limitless splendour and variation, but now it is a pale, faded, ragged remnant sucked dry and spent of all joy. To one dedicated to Slaanesh, such a fate is terrible indeed and one that all but those who achieve apotheosis and are granted daemonhood are doomed to meet.

…

Having made it so far, some mortals simply keep going, passing out of the knowledge of the tribes and into the far north, where the lands writhe and the skies boil under the baleful influence of raw Chaos. Whether they enter the Realm of Chaos itself or pass into some other unfathomable reality, none can say, though certainly they do so in the name of the Dark Prince.

Liber Ecstatica: The Book of Pleasure (2009), pp. 7-8.

I feel the latter part of evokes the much later lore about Syll’Esske I covered in part 1.

In 2008, an interview with the GW design team about Daemon books which were being released in sync for WHFB and 40k was published, which noted that there was a lot of crossover within each:

If you put the two books together you'll find that these strange mythic characters appear in both, but one is looking through the Warhammer mirror while the other is from the mirror of the 40K galaxy. Make no mistake though, these are the same daemons –  Skulltaker, Khorne's greatest champion, is the same being no matter what planet or battlefield he strides across.

White Dwarf 341 (2008).

If we then look at these books, what are quite ambiguously phrased statements could perhaps be read as referring to just either the Warhammer World and the Warp or the 40k galaxy and the Warp – or, could perhaps be read as referring to a multiverse.

Note that this idea that the Warp is the same but perceived and understood differently on the Warhammer World versus the 40k galaxy has a long pedigree, going right back to the first Realm of Chaos volume in 1988. Whether the Warhammer World was being conceived by the author here as being in a separate reality to 40k, or a planet within the galaxy, is a bit unclear, which could make the following quotes read differently.

About the Masque of Slaanesh:

So has the Masque been doomed ever since. She dances across the mortal and immortal planes to music only she can hear, never able to rest.

Warhammer Armies: Daemons of Chaos 7th ed. (2008), p. 58.

And:

With every stir of Nurgle's maggot-ridden ladle, a dozen fresh diseases flourish and are scattered through the universes to bring low civilisations and destroy the populations of worlds.

Codex: Chaos Daemons 4th ed. (2008), p. 13.

And, the quote we saw earlier:

Atop a palanquin carried under a mound of straining Nurglings, Ku'gath moves across the universes searching for the combination of blights and woes that will create his perfect disease.

Codex: Chaos Daemons 4th ed. (2008), p. 48.

And:

It is said that when Khorne first created the Daemon U'Zuhl, the Bloodletter's first act was to chop the head from the first creature he met – another Bloodletter. So began an existence of decapitation that has spread terror throughout the mortal and immortal universes.

Codex: Chaos Daemons 4th ed. (2008), p. 50.

And:

Guided by his plague-sense, Epidemius follows the filthy spoor of his master's work through both the Daemon and mortal realms, seeking out new strands of virus, fresh species of bacteria and innovative symptoms of contagion.

Codex: Chaos Daemons 4th ed. (2008), p. 52.

This two are more clearly talking about a multiverse though:

As with all worldly things within the Realm of Chaos, Nurgle’s overgrown garden is of a scale large enough to befuddle the mind. Within its bounds are the plants and trees drawn from a thousand worlds across a hundred realities.

Warhammer Armies: Daemons of Chaos 7th ed. (2008), p. 11.

And:

From one end of the multiverse to the other, across space and time, Karanak is the incarnation of Khorne's vengeance.

Codex: Chaos Daemons 4th ed. (2008), p. 55.

And, going on to other sources:

'You must listen,' pleaded Eldrad. 'The warp, as you call it, is home to the most malign beings imaginable, terrible energies that are elemental and ferocious. They are gods that have existed since the dawn of time and will outlast this guttering flame of a universe. Chaos is the worm at the heart of the apple and the canker in the soul that devours from within. It is the mortal enemy of all living things.'

McNeill, Fulgrim (2007), p. 267.

Which suggests they are not connected solely to the 40k universe.

And:

As he stared into the lidless eyes of the image, they fixed upon him, and he felt the painting's leprous visage peel back the layers of his soul as it hunted for the darkness within him that it would bring forth and nurture. The sense of violation was horrific. He dropped to his knees as he fought to avert his gaze from the burning cruelty of the painting, and the terrifying void that existed beyond its eyes. He saw the birth and death of universes in the wheeling stars of its eyes, and the futility of his feeble race in denying their every whim.

McNeill, Fulgrim (2007), p. 332.

And one which is a bit ambiguous, but suggestive of multiple realities, while talking about a daemon, and hence the Warp:

A terrible, ageless scream of frustration filled the chamber, echoing throughout all the realms of existence as a creature older than time was thwarted in its ambitions.

Scanlon, Descent of Angels (2007), p. 619.

And, mixing up with another word:

The forms the live-things called Chaos, in their limited little ways of perceiving the omniverse, swarmed and thrived in this infinite ocean of mind and emotion. The Daemon moved with Stele. Waiting, waiting and watching for the moment when the thrashing and chattering of the quarry was at its peak. Only then would it strike, lapping up the absolute perfection of its fear, sinking in rending teeth, tearing it to soul-shreds.

Swallow, Deus Sanguinius (2005), p. 106.

And another passage related to parallel, branching realities, and the Warp’s relationship to reality creation:

Was this infernal engine somehow capable of traversing the currents of the warp? Was that how it had managed to intercept Calth’s Pride within the treacherous shoals of the immaterium?

…

'You should honour me, for you travel in ways no mortal has dared for aeons.'

The Omphalos Daemonium raised its arms to the ceiling and laughed.

'We travel the bloodtracks. The Heart of Blood and the daemonculaba await!'

And the daemon engine roared into realms beyond existence.

Uriel screamed.

Space folded, the currents of the warp vanishing: the arena, the daemon engine, the firebox, Pasanius. All disappeared, ripped away as everything around him turned inside out and became meaningless concepts. He felt himself simultaneously explode into a billion fragments and implode within himself, compressed to a singularity of hollow existence.

Faces floated before him, though as a dense ball of nothingness and a fragmented soul he knew not how he recognised them. Worlds and people, people and worlds, flashing past in a seamless blur, yet each as clear as though he examined each one in detail. Time slowed, yet rushed, splintering crystals sounding from far off as fractured realities ground and shifted like tectonic plates.

He saw the daemon engine spiral through the cracks between dimensions, snaking a path that wound through the shifting glass shards of reality, existing outside of everything, travelling in the slivers of null-space between all that was and all that ever could be.

…

Every action that spawned a new realm of possibility could be found here and Uriel felt the knowledge of such things fill him as he hung from his hook, bleeding and raw.

McNeill, Dead Sky, Black Sun (2004), p. 33-35.

And:

From the designs of the Old Ones, it was the Slann who built the immense constructions that hung like moons above the northern and southern poles - gateways that enabled instantaneous travel through rifts in space, doorways to uncountable realities.

Warhammer Armies: Lizardmen 6th ed. (2003), p. 4.

And after describing what somebody journeying north through the Chaos Wastes would experience, were they then to cross over through the rent in reality at the pole, we are told:

Were our traveller to step over that boundary, he would not find himself lashed by storms or shrouded by night but swallowed into a region of infinite space altogether removed from the mortal world. As words alone are incapable of describing that which lies beyond oblivion’s veil, no more can mere mortal thought convey the weave in the fabric of the timeless multiverse. Thus we must leave our traveller at the Gates of Chaos where we are unable to follow, even in our imagination.

Warhammer Armies: Hordes of Chaos 6th ed. (2002), p. 6.

And:

Of these gods, the greatest of all are the four that are called the Dark Gods. The unwitting creations of Mankind's most powerful subconscious emotions, they may be summarized (if imperfectly) as rage, hope, despair, and pleasure. They are Khorne the Blood God, whose bellows of rage echo across the multiverse, Tzeentch the Changer of the Ways and master of the weave of time, Nurgle the Lord of Decay, whose rotting carcass oozes corruption, and Slaanesh the Dark Prince, neither male nor female, whose beauty is such that the merest glimpse will bind a mortal to his eternal service.

Warhammer Armies: Hordes of Chaos 6th ed. (2002), p. 15.

And, as I covered in a previous post, the Wiliam King short story ‘The Ultimate Ritual’ originally published in 1999 perhaps showcases multiple realities/universes, though it is a bit ambiguous (though it most definitely showcases a connection via the Warp between the Warhammer World and the 40k galaxy): https://madministratum.blogspot.com/2025/08/that-time-two-wizards-took-tour-of-40k.html

And:

The last door opened before Witch Hunter General Gunther Munz. Now he finally stood atop the

Impossible Fortress, his quest to slay Amon' Chakai was near its end. He stepped into the Chamber of Glass and saw the Greater Daemon sitting upon his throne deep in meditation, its omnipotent will travelling the vastness of the multiverse.

Warhammer Armies: Champions of Chaos 5th ed. (1998), p. 20.

And, alongside some articles to introduce the then new Great Unclean One model:

“From his home in the Warp the Great Unclean One has burst forth to wreak havoc across the battlefields of both Warhammer and Warhammer 40,000.”

White Dwarf 207 (1997), p. 5.

And:

Across a rotting bridge of damnation, the Greater Daemon of Nurgle emerges into the worlds of both Warhammer and Warhammer 40,000.

White Dwarf 207 (1997), p. 51.

And:

The Horned Rat is feared and worshipped as the patron deity of the Skaven. The mighty Chaos Power gnaws at the fabric of the multiverse, instigating the forces of decay. The Horned Rat's image and symbols appear on clothing, tokens and as part of Skaven ceremonial worship.

White Dwarf 119 (1989), p. 67.

And a statement about there being lots of universes, though the figure of a million I think we can take to be poetic licence rather than a specific number:

A miss indicates that the missile has left Warpspace at the wrong point – and this could be anywhere in any of the million universes.

Adeptus Titanicus (1988), p. 37.

And, though more tenuous, we have this description of Keepers of Secrets (though it is worth noting that the rest of the book doesn’t discuss a multiverse):

It is also said that they can hear anything that is said anywhere, in any dimension, and thus they are called ‘The Keepers of Secrets’. They may trade their knowledge for gifts or services.

Realm of Chaos: Slaves to Darkness (1988), p. 30.

Note also, as I discussed in another post, GW also linked their games/settings 40k, Talisman and Chainsaw Warrior as well as other unnamed realities together, via the reality-hopping Talisman: Timescape in 1988: https://madministratum.blogspot.com/2025/06/a-space-marine-astropath-and-indiana.html

And, finally, some reaaaaaaaally old ones here (pun intended, given the Slann link), showing that the concept was introduced very early on indeed:

In the realms of psychic-philosophy and mystic-technology the Slann certainly have no equals, fulfilling themselves by study of spiritual life-forces and the secret powers of other realities.

Warhammer 40,000: Rogue Trader (1987), p. 194.

Note that it says other realities, not just another reality (i.e. just the Warp).

And:

This unimaginably ancient race spread throughout the galaxy, discovering many strange secrets and harnessing the unseen powers of the multiverse.

…

Having gained access to warp-space, the Slann also gained access to all points of the universe and to other undreamt of aspects of the multiverse.

Warhammer Fantasy 3rd ed. (1987), p. 189.

Of course, these Slann fellas have been important in other posts I have made about the connections between Fantasy and 40k.

Conclusion

As you can see, there was a big gap between when the concept of a multiverse was first mentioned in the 1980s and when it was later appeared in the lore (starting in the late ‘90s, but really taking off in the mid-to-late 2000s) – but the precedent was there from the very start. And Warhammer lore has always been peppered with these elements which may seem inconsequential for a long time, and then be expanded upon and developed much later. It is also worth noting that the exact nature of the multiverse, even on as basic a level of what scale it operated it and how many realities it encompassed (just the “Warhammer reality” where the Warhammer World was a planet in the 40k galaxy and the Warp and its many sub-realms? A million realities? Myriad or even infinite realities? etc) was rather ambiguous, and only seems to have more uniformly settled into a more (but perhaps still not wholly) consistent depiction in the past 20 years or so, where it is clearly encompassing innumerable, if not infinite, realities.

The main take away here though is that while the concept of a multiversal Warp has perhaps become more foregrounded in recent years (or at least more explicitly stated), it was evident in the lore since the very start of 40k.

Moreover, the concept has appeared in rulebooks, Codexes, Army Books and campaign supplements etc for the main Warhammer Games, as well as Black Library stories, and White Dwarf and Warcom articles, RPG material and computer games. And it has been evident in lore for 40k, Warhammer Fantasy, Age of Sigmar, Blood Bowl spin-off games like the old Adeptus Titanicus, and games like Talisman. So, while references to a multiverse have always been very, very sparse (and thus easy to miss and overlook), they have appeared in a lot of different forms of Games Workshop content, which is interesting and speaks to the enduring influence of the idea.

It is also interesting to see which particular Black Library authors have utilised the idea (hence why I supplied the names of BL works). Certain authors seem to have engaged with it and/or promoted it more, most notably Graham McNeill (himself a former games developer), but also Guy Haley, and, for a brief time, Josh Reynolds.

My feeling is that the concept has likely often been contested by those who write GW lore (as indeed has the idea that the settings are linked in some form). So, sometimes it has received less prominence, but other times, more, depending on who was writing what, and their feelings towards the concept. Some authors just won’t ever use the concept, and perhaps to them it doesn’t exist in their own view of the setting(s). But other authors do use it. And that means, as regards the published lore, it keeps getting mentioned, and thus is very firmly part of the official lore – and GW has leaned in to making official statements about it pretty explicitly in the past few years. They never at any times made any official statement about the Warp not being multiversal and/or the settings not being linked.

Anyway, I hope this was post was of use. I will finish off this miniseries with a commentary on the recent White Dwarf article on the place of Chaos in Warhammer, by games developers Phil Kelly and Andy Clark, so keep an eye out for that.

As always, if you think I have missed any examples, please do mention them in the comments. Let’s make this as useful a resource as possible.
