Water Caste

The Water Caste is made up of merchants, diplomats, and administrators. They are responsible for maintaining effective interaction between the castes, as well as communicating with and supervising the integration of alien species into the Tau Empire. Members of the Water Caste tend to be taller and slender than other Tau, and their features are softer and more expressive. Water caste Tau will frequently adopt mannerisms and cultural habits of the races they deal with, although this is often done to promote communication with other races.
