The Tau started as a classic case of successful design-based trolling on the part of Games Workshop. Although a dystopian society in its own right, the Tau Empire is noted for being one of the LEAST awful places in all the galaxy of 40k. They were growing until recently, when the Imperium sent a large invading force to counter them. Their planet was then trapped in a warp storm for a few thousand years and they emerged from the other side as a unified species, led by the mysterious Ethereal caste and devoted to the concept of the " Greater Good ". When first discovered by humanity, the Tau were a barbaric and primitive people.
