The Tau seek to bring enlightenment and unity to those who join them. While the races of the galaxy tear one another apart, the Tau grow stronger and stronger. On the Eastern Fringe, far from the power of Terra, world after world has fallen to their dynamic advance. 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 into battle carrying weapons of immense power, encased in battlesuits that can withstand the fiercest of attacks. Led by the mysterious Ethereals and accompanied by alien allies whose cultures have been subsumed in their empire, the Tau believes that the very stars themselves will be reforged in the cause of the Greater Good.
