T'au

T'au is the homeworld of the Tau Empire. It is located within the Ultima Segmentum, to the galactic north of Ultramar. The planet itself is a hot, dry, arid world primarily covered in savannah and scattered mountain ranges. What arable land is covered with efficiently run collective farms managed by the Earth Caste. Cities rise into the sky, covered in white marble. They are very different 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. The planet has seven moons.
