== Fio - Earth Caste ==

This caste provides for the manufacturing, agricultural, industrial, artisans, and engineering needs of the Tau Empire. By far the largest caste in sheer numbers, it is they who erect dwellings, provide food, and produce new technology. Members of the Earth Caste are often described as plain and dour, possessing a rather stoic outlook on life in general. They were originally the first Tau to build cities and practice agriculture. The city of [[Fio'taun]] is an example of this, being the first place where the [[Ethereal]]s appeared.{{Fn|6}}

===Notable Members of the Earth Caste===

==Kor - Air Caste==

The Air Caste is charged with holding the Tau Empire together through the [[Kor'vattra]], the Tau Empire's merchant and war-fleet in addition to operating [[Tau Orbital]]s and [[Fortress Station]]s. Formerly functioning as messengers, these days they are the Tau Navy and are sometimes called the "Invisible Caste", for they rarely if ever set foot upon planets. Living in [[Orbital City|Orbital Cities]], Tau of the Air Caste are the tallest and most slender of all Tau, with long, skinny limbs and hollow bones developed due to lives lived mostly in low- and zero-gravity ships and space stations. In the past, before the time of the [[Mont'au]], the Tau that originally became the Air Caste had membranes stretching between their limbs, allowing them to glide on air currents. Tau pilots tend to be superior pilots compared to their human counterparts because they have a better depth perception and higher G-tolerance, but lack battle-experience compared to the best Imperial fighter-pilots.{{Fn|6}}
