Editing Tau (section)

===Psychic/Chaos Defenses===
Tau as a species are comprised of psychic blunts. They cannot produce psykers and have limited innate resistance to some forms of psychic powers and daemonic bullshit. People often mistake this resistance to outright invulnerability, but in truth it's more akin to camouflage. Tau DO have souls, but their souls cast such a dim light in the Warp that they are, at best, indistinguishable from the spirits of non-sapients, and at times they even blend into the psychic background of inanimate objects. This may have something to do with how unemotional Tau are, as some of the more descriptive bits of fluff demonstrate how warp shenanigans like faint whispers and creeping feelings of "wrongness" may cause humans to freak out and try to run away immediately, the more calm and collected Tau don't notice anything strange at all. Likewise, if a psyker tries to mind-rape a Tau or a daemon tries to posses a Tau they'd find it hard to find a soul to target at all, but in the unlikely event that they were somehow successful, there would be even less resistance than with regular humans. Sadly while this trait is often shown in the fluff, it does not affect Tau crunch in any way aside from their total lack of psykers.

This innate defense is further strengthened by the Greater Good philosophy deeply indoctrinated into each Tau from childhood and reinforced through the subtle control exerted by the Ethereals. Tau'Va is the antithesis of all the creeds of Chaos, which makes Tau all but immune to its temptations, and only two Tau have ever actually fallen to Chaos. The first was the Water Caste member Water Spider, who was possessed by a Daemon of Tzeentch - although, rather amusingly, the daemon forced Water Spider to become obsessed with the truth, something abhorrent to the Water Caste. The second was [[Warhammer 40,000: Fire Warrior|Shas'la Kais]]. Though Kais was untained in the video game adaptation, the much better novelization had Kais getting an assist from Khorne throughout his adventure, though he was permanently scarred by Khorne's influence and the conflict. [[Grimdark|This left him permanently insane and hospitalized, unable to meaningfully respond to his friends and environment]].) That being said, the Tau have only just been exposed to the more material horrors of the galaxy; should they become jaded and start losing faith in the Greater Good (as inferred with giving up on indoctrinating certain species), well, that would be an entirely different situation. Their allies, including the Kroot, have sometimes been known to go all-in with Chaos worship, although Tau seldom take culture from their allied races.

8th Ed is here, and has confirmed that the Tau aren't immune to Chaos, just rather difficult for Daemons to spot. When the Tau started the 4th Sphere Expansion with their new warp drives they didn't take a note from the Imperials' tech and failed to invent the [[Gellar Field]] too, meaning they were fully vulnerable to the Warp's denizens. The entire experience was hilarious. First was the unpredictability of their warp drives (known as "slipstream technology" to them) that caused most of their expeditionary fleet to be destroyed due to unleashing massive tears in the fabric of reality, [[lulz|while being broadcasted to the Tau sept worlds, causing the Ethereals to rapidly evacuate their bowels as they scramble to censor the event for the wider populace.]] Those that weren't immediately torn up by the warp rifts were sucked into the Warp where a vast majority was either destroyed after drifting in the more unsavory parts of the Warp or by the various daemons mucking about.

Contact was lost, but the Tau managed to find the survivors later, nestled into several worlds that were the original target for conquest. The Tau that survived, however, were acting weird. Some of them had clearly rejected the Greater Good, while some worshiped a voice that they claim to be the Greater Good itself (which may or may not be a warp entity), while some were outright driven insane. A disturbing trend about them was their total [[Imperium|xenophobia and brutality]]. Any non-Tau who wasn't driven off from the 4th Sphere colonies were murdered because [[Chaos God|something]] was telling the survivors that the auxiliaries were the reason for their loss and torment due to their more powerful connection to the Warp.

That being said, they're still hard for Daemons to see, considering that the Fourth Sphere dove into the Warp unprotected and "merely" got off with plain Chaos corruption when most people who try that shit critfail their [[anal circumference]] roll and either gets torn apart by daemon cocks or becomes [[Chaos Spawn|a Chaos spaaauuuughgghblblblbbl-]] <span style='color:blue;font-size:115%;font-family:serif'>*PEW* The Greater Good grants you mercy, gue'la.</span>

Also, the 8E Daemons Codex does mention one Tau agri-world that was cut off from supplies, eventually succumbing to the native faith revering a certain "Rainfather" - [[Rotigus]] Rainfather, a notorious [[Great Unclean One]].

As always, any inconsistency on how the Tau are, or aren't, affected by Warp exposure is entirely GW's fault.

nother element about the Tau is while they're not, generally (See above) Xenophobic, this means that though they are psychic blunts, other members of their society are not. Even though this is the most obvious fact in the universe GW tends to utterly ignore this both in terms of crunch (Tau have never had psykers on the table top even though just making the psyker a different species than the Tau solves this issue), and fluff (bluntly it's never brought up).
