Young and ambitious, united in their purpose, the Tau seek to bring enlightenment and unity to those who will join them. While the Imperium crumbles and is beset on all sides, the Tau Empire grows stronger and stronger. In the Eastern Fringe, far from the power of Terra, world after world has fallen to their dynamic advances. Yet there are those who fail to see the benefits of becoming part of the Tau Empire. Any resistance is swept aside, whether it is philosophical or physical, for the Greater Good can overcome any obstacle.

At the forefront of this rapid expansion are the warriors of the Fire Caste. Unfettered by Mankind’s superstition and fear of technology, the Fire Warriors go to battle carrying weapons of immense power, encased in battlesuits that can withstand the fiercest attacks. Stealth and Pathfinder teams scout out the foe for the Hunter cadres to engage, using swift movement and immense firepower to destroy their foes from afar.

At the heart of the empire are the Ethereals, spiritual rulers of the Tau. Though rarely seen, their presence is felt on every Tau world. Many other races are part of the Tau Empire, such as the Kroot – mercenaries whose speed and strength make them natural fighters. Other aliens, some coerced or conquered, lend their own abilities to the Tau, united in their cause to bring the Greater Good to other worlds and peoples.
