The third edition Tau Codex said that he found it ion "the dead world Arthas-Moloch. If there was a chaos cult there, was it made dead by Exterminatus after the fact, or was the world already dead when the cult was active on it? Or is this another fluff inconsistency?

Now after read the book Xenology (i can't spell) In the book they did dissections of Xenos and with the tau it was a eternal and they found a little crystal in there forehead it was some kind of a gal which puts out scents like a queen ant for mind control of the species didn't Farsights eternal died in a battle ? maybe the mind control scent is now gone and thats why he's AWOL

... Its Etheral first of all. And yes his etherals did die on Arthas Moloch. In the fluff I read the Scythes of the Emperor killed the cult on the planet then did that exterminatus thing.

OR maybe it's a Tzeenchian blade. Tzeench schemes for the heck of it, so it would be reasonable for him to cause trouble amongst the Tau. Maybe the Chaos gods hate them for not having any Psykers to corrupt.

Or maybe the Ethereals are preventing the Tau from being psykers, its all possible

My bad

No, Tzeench seems the best bet for me, he may want to use Farsight's Tau to overthrow the Ethereals so Tzeench would have an entire race at his disposal.

Maybe, but as you said earlier the Tau have no psykers to corrupt, therefore even if farsight did overthrow the Ethereal chaps then none of the Chaos Gods would really be able to exhibit any control over the Tau in the end.

Importantly who made the Tau in the First place? As that might give some answers to different stuff

a remaining Old One will do,
because they created many folks
todo their wishes.

maybe it was the old ones but the races the old ones created were highly psycic (eldar and orks) so why change that in the tau

the Tau should glue together the
other races with their "greater good"
when solo action by eldar,ork or
humans failed them.Tau in their
servant mood are more controllable.

It's possible that the Ethereals are the ones responsible for suppressing Tau psychic abilities.

What the real question is who made the Ethereals or where they came from. In the fluff the tau were at war all the time until the ethereals came

1.the etherals were enhanced leaders inserted from
outside and would be Tau before.
2.a speedup in evolution and technics is also external inducted.

Only ancient and fixed on subordinates to do their cause
races will fit.
Old ones - High possibility
c'tan - max be
Third Party??

Am I the only one a little worried by how the Tau social system is like the Eldars?

Confused, Ok I'll explain, the Eldar have the Paths to stop them 'going insane or something' and the Tau have a very similar thing, with Tau following only one thing-ie war, diplomacy, Etherealness. Anyone else think maybe theres a connection?

Also what bugs me is that the Tau were forced to 'hyper evolve' by warpstorms that surrounded the planet, or so I belive, (correct if wrong) and the warp=psykers, so why the hell did the Tau not gain any? It makes no sense!!!

he tau were cut off by warp storms but it doesnt mention anywhere that the stroms made them evolve any quicker than they would have normally

even so, the warp storms cut off surely would have had some backlash on them, afterall if you sit under the sun too long you get burnt, if you sit under the warp too long...you...*trails off*...I'm not really sure how to finish that sentence...

Well the warp storms didn't affect them they just cut em off and they did not "hyper evolve" they were just able to advance their technology without outside interferance which would have severely slowed this process if not killed them off entirely. Because of this they had all the time in the galaxy to focus on their research and technology without fear of attack. hence them being one of the most technologically advanced races in the game...er galaxy.

those warpstorms didn't came without reason.
someone wanted them to be Cut off.
