Ethereal Caste

The Ethereals are the political and religious leaders of the T’au. They resemble the Fire and Water Castes physically, but are marked by a diamond-shaped ridge of raised bone in the centre of their foreheads. Their origins are unknown, and most T’au will never refuse a request made by an Ethereal. They are sometimes also found on the battlefield, but whether as leaders or observers remains to be seen. The leader of the Ethereal Caste is a T’au named Aun’Va, the Ethereal Supreme and Master of the Undying Spirit who chaired the Ethereal High Council and served as the head of state or Aun’o of the T’au Empire.
