“The Greater Good demands that no obstacles stand in the way of the Tau. If we must, we will force your compliance at the point of a gun.”

— Shas’O R’alai to the defenders of Malanthar VII

The young and idealistic blue-skinned Tau race possess a small empire in the Eastern Fringe of the galaxy. The Tau command technology far more advanced and innovative than humanity.

Only a few thousand years separates the T’au Empire their primitive ancestors. Against the Imperium’s millennia long history, the Tau only recently rose to prominence.

Yet they impact their region of space, spreading rapidly and forging alliances with numerous minor alien races to create a potent empire which presses against Imperial borders. Their philosophies of unity and collective endeavor with other races present a greater danger than their advanced weapons and void ships. Centered upon a belief in the “Greater Good” and a common goal of balance and equality, these alien lies seduce many humans.

The Tau pose as a peaceful race, asking others to join their cause voluntarily instead of fighting against them. However, if refused, the Tau typically invade and conquer a planet and add it to their growing interstellar empire for the Greater Good, searing the flesh from the bones of anyone who stands against their “benign” intentions.

As the Tau Empire continues to encroach on Imperium space and places an increasing drain on the Imperium’s already dwindling resources and presents an increasing threat.
