The planet itself is a hot, dry, arid world primarily covered in Savannah and scattered mountain ranges. The little arable land is covered with efficiently run collective farms managed by the Earth Caste. Cities rise into the sky, covered in white marble, in stark contrast to the Hives of the Imperium. No humans have ever walked on the streets of the capital, located on the equator, and Imperial scans are blocked by some Tau technology. At the centre of this city appears to be a heavily defended fortress, possibly the heart of the Tau empire, the high council of the Ethereals.[Needs Citation] T'au is home to a large moon known as Lu'val, which was the first off-world colony of the Tau Empire in 533.M37.
The planet was discovered by the Imperium at 789.M35 by the Land's vison, an explorator vessel of the Adeptus Mechanicus. Shortly after that it was surrounded by vast warp storms, cutting off the entire region. Only six thousand years later, the Tau Empire spanned 300 light years.[Needs Citation]
When the Imperium first arrived in the vicinity of T'au, it was a feral world with primitive people scraping a living off of the ground. When the Imperium returned following the warp storms, they attempted to conquer the Tau empire, and were successful in conquering quite a few planets. However, they were forced to pull back in light of the advances of Hive Fleet Behemoth. It is designated a Xenos World by the Imperium.[Needs Citation]
The warriors which comes from T'au are known as wise and experienced troops, coming from the original Tau explorers who fought the first battles during the initial expansion phase of the Tau Empire. T'au is also the template upon which newly founded colonies are based. The battlesuit combat techniques in use on many new Tau worlds are the same as those practised by those from T'au. Their warriors tend to forgo the ability to target multiple enemies, concentrating instead on utterly destroying a single unit before moving on to the next. This way they achieve maximum destructive efficiency. They are aware that by using the same or similar tactics, their enemy may be able to overcome them, but they are loath to change them. Their warriors spend evenings planning in detail the next days' attacks and meditating on their lives in case they fall in battle.
