Little is known of the Tau Ethereal caste, appearing as shrouded, enigmatic figures that eschew the advanced equipment favored by the Tau Fire caste. Ethereals seem to combine the roles of priesthood and royalty within Tau society, and command unquestioning loyalty from all of the other castes. Ethereal caste members are occasionally seen on the battlefield, although whether leading or observing is unclear.

A Tau Ethereal caste member may be added to your Tau army as an HQ choice.
