Throughout the 40K books Humans seem to be the main conduit for Chaos, are there any other races that worship, or have been known to worship, the Chaos Gods, either directly or indirectly (they worship a Chaos God without knowing that is what it is)?

I realize the Eldar brought about the creation of a chaos god through their actions, but this event predates the 40K books and by this time Eldar (both light and dark) no longer worship the gods of chaos.

  • "by this time Eldar (both light and dark) no longer worship the gods of chaos." As far as I know, they never did. Slaanesh was an unforeseen and undesired by-product of their fall into lust

Almost any race (with the exception of Necrons and Tyranids) has Chaos worshippers:


While Orks normally worship Gork and Mork, there are on occasion warbands worshipping Chaos goods, especially Khorne - after all his ideology is quite close to the Ork one, although Orks fight because this is "fun thing to do" rather than to spill blood for the sake of it. Other Orks, can instinctively find such boyz as un-Orky, so the life of such chaos warbands is usually pretty short.


Contrary to the popular belief, Eldars don't worship Slaanesh - for both Dark and Craftworld Eldars this would be a suicide. But that doesn't mean that they won't fall prey of the other gods - Harlequins often bring information about cut off parts of the webway or the Crone Worlds that survived in the Eye of Terror full of mutated, crazy Eldars, that (for the lack of other option) sold their souls to Nurgle or Tzeentch to prevent being devoured by She-Who-Thirsts.


Tau are mostly immune to Chaos, because they have "dim souls", which makes them almost invisible to the warp. But that doesn't mean they are completely immune: in recent years they've managed to reverse-engineer Imperial warp drive but decided to ignore the protective Gellar field. The effect was disastrous and almost destroyed the fleet from the Fourth Sphere of Expansion, who went into warp without any protection. But even before that, many Tau who were exposed to warp-tainted artefacts (or even the warp engines) were hearing strange voices... and some started to follow them, abandoning the Greater Good.


While many Kroot follow their Tau masters, there are quite a lot of independent packs often working as mercenaries. The most interesting part about Kroot is the fact, that their DNA changes depending on what they eat (i.e. eating Dark Eldar would make Kroot more agile... but also cruel) - hence their Shapers lead them in the fight against powerful beasts that can enrich and enhance their traits. While this is forbidden, some of Kroot feed on the tainted Chaos flesh (often unintentionally - human chaos cultist might look like an ordinary man), which leads to corruption - after all, the Changer of Ways would look favourably on those, who can change their flesh on demand.

Lesser races:


This race was described in the "Eisenhorn" trilogy. At some point in their history, they've been contacted by human cultists, who offered them a powerful tome called Necroteuch, which slowly corrupted the whole race destroying their small empire.

Yu'vath and Bale Children

The Yu'vath were a Warp-worshipping xenos species, who built an empire of corrupted humans and were defeated in the Angevin Crusade, together with the Bale Childer, after the homeworlds of both species were destroyed by Exterminatus.

The list of sentient species is long...

  • What happens if Kroot eat Tyranids?

    @JAB It is forbidden, but it has happened at least once: The effect created a very powerful pack full of horrible monsters. Sadly it seems, that most of the Kroot went insane with this change.

    @JAB also, they find genestealer-tainted flesh to have a bad taste (from the Cain books) Mar 5, 2019 at 21:21

Sort of

There are races scattered throughout the Horus Heresy novels that worship Chaos gods or demons. They're usually only plot devices that exist for the duration of that novel though.

As far as the main races in 40k are concerned, they all have their own sort of unique quirk which gives them immunity from the Chaos gods.

  • Necrons have no souls so Chaos gods don't waste their time with them.
  • Tau are so focused on the Greater Good they are supposedly uncorruptable.
  • Tyranids are basically cut off from the warp.
  • And so on...

There are always exceptions to these rules however. You'll find the occasional corrupted Tyranid, Ork or Necron construct here or there but for the most part, the Chaos gods focus mainly on humans. We are the easiest to corrupt and we taste the best.

But of course, in a pinch, there are always the Chaos Squats.

    I thought the Tau simply didn't have enough presence in the Warp to be corrupted. That was portrayed in the "Dark Crusade" game, with the Tau Commander unwillingly trolling Eliphas because he couldn't hear his whispers (see the following video): youtu.be/QPeNOEdVmbc?t=94

    @Clockwork I actually didn't know the reason the Tau got a pass. I assumed it was the Greater Good thing, thanks for the update!

Yes pretty much any psychic capable race. So you know about the Fall of the Eldar most notably. so I won't go over that.

[Not much yet but will add more]

The Laer

Before the Horus heresy The emperor's children exterminated the planet Laeran during the 28th Expedition. Which was home to the Laer Which where fanatic worshippers of Slaanesh.

  • sorry I have updated the question I now about the eldar but by the time of the 40K universe they have stopped worshipping chaos.

  • @RichardC Exactly, thoug their is a case I know for sure where a Eldar Warlock That was corrupted by Tzeentch. But as you said actual worshipping I don't really know any Full races that actively worship any of the 3 ruinous powers.
