The T'au Empire is amongst the most dynamic and determined powers in the 41st Millenium. Their technology is advanced and ever-improving, from grav-skimming gunships and artificial intelligence, to potent energy weapons and formidable battlesuits. Their territories expand with every victory, be it military or diplomatic. Yet the T'au Empire's greatest strength is its unifying philosophy – they believe it is their duty to spread the doctrine of the Greater Good to every corner and culture of this dark galaxy, and will let none stop them from bringing enlightenment to the stars.
