T'au

Castes

Tau society after the arrival of Ethereals was organized into castes; everyone with a place, and a place for everyone. Interbreeding between castes and Xenos races is one of the most severe crimes in the Empire, in other words, Heresy. This was outlawed by the Ethereals presumably to preserve the biological differences between castes; the result is the creation of 5 sub-species. Tau society does have many examples of romance, and there are designations of 'pair' bonding at least amongst the Earth Caste. The Tau have children which they both raise and also send the creches but they seem to monitor birth rates (likely to match resource levels as well as provide an additional level of social engineering).
