Changes

Each caste is named after an element of nature, symbolising the purpose and temperament of the caste's members. A Tau's caste is determined at birth and inherited by one's parents. Inter-breeding is forbidden by the [[Ethereal]]s. For a Tau to choose another caste for himself seems to be impossible, and held contrary to the notions of the [[Greater Good]]. The castes are based upon the racial and political divisions that separated the Tau on their [[homeworld]] of [[T'au]] during the time of the [[Mont'au]].The Castes were first formally established after the Ethereals brokered peace between warring Tau factions at [[Fio'taun]]. Emphasizing the need for the Greater Good, the Ethereals decreed that the Tau would be formalized into a caste, each known by the element that most befitted its role in the new Tau society.{{Fn|6))
