The Farsight Enclaves, known as the "Forbidden Zone" in the T'au Empire, are a series of heavily-fortified T'au colony worlds that are independent and indeed opposed to the rule of the T'au Empire and its Ethereals. They are ruled by the legendary Fire Caste Shas'O Vior'la Shovah Kais Mont'yr, known to the Imperium as Commander Farsight, and lie on the far side of the Damocles Gulf region of the Segmentum Ultima in the Eastern Fringe of the Milky Way Galaxy.
