Welcome to Librarium Online!
I have read about a story where the Tau fight some humans and it turns out they are slaaneshi cultists. They are constantly saying "We serve slaanesh" and other things. Tau mistake the spess mehren leading them as "slaanesh" and go around saying "we have killed slaanesh" and tell the Eldar "we have defeated your immortal enemy, join the greater good"
Although i am not so sure about the Eldar part.
“When I give food to the poor, they call me a saint. When I ask why the poor have no food, they call me a Communist.”
Yeah, I've read that one..
Summary: Tau fight scary humans and are a bit creeped out. They win and capture one who says he serves Slannesh. Tau assume Slaanesh is the leader of the warband. Some of the Kroot eat the chaos cultists.
Anyway, they find the main warband and assume the big guy leading it is Slannesh. Tau get really scared because 'Slannesh' has scary mind altering powers, also the Kroot who ate the cultists mutate and attack them. It's not looking good, but then the Tau commander kills 'Slannesh', horde scatters, Tau go yay!
Story ends with Tau commander commenting how good it is that Slannesh was stopped because he was really scary and how passions need to be avoided.
No Eldar unfortunately.
The next book is about slannesh getting pissed off at this blasphemy and kills everyone?
Not really, it was only a one-off piece somewhere, so I wouldn't expect a sequel any time soon
The_Giant_Mantis has it right, though. From what I remember (I can't find the piece in either codex I have, so maybe it was in a White Dwarf somewhere?) the commander narrates the story, commenting on the unnatural appearance of the foe, the strange musk that seems to affect the enemy warriors (and the Kroot which feasted upon the chaotic dead, and even the commander to some degree) and how the effect disappears when the leader of the Slaaneshi horde is dispatched, leading to a complete collapse of enemy morale.
I'm not sure if the commander actually comments on the manner in which the Ethereals command a similar power over Tau as to what this enemy did over his minions, or if I'm confusing that with something else.
Also, absolutely no mention of Eldar. And I don't think the Tau are exactly leaping around with excitement that they 'killed Slaanesh', either, as they don't actually perceive him/her as a deity - to them it was just the name of this insignificant warlord.
Wow, no wonder everyone calls the Tau naive. Are they that ignorant of the Warp and the Ruinous Powers?
i guess in this case ignorance is bliss.
Though they do know what a warp rift is and know that its bad for them, and that the things that errupt from them usually need to be killed quick.
Man, what does humanity need with the Warp anyway? Most of humanity's current miseries can be traced to the Ruinous Powers. The Tau do quite splendidly without Warp sensitivity. Humanity should explore ways to sever their connection to the Warp.
Isnt tapping into the warp how one uses psyker power's?
Support you right to play video games, its for the greater good...
