The Fire Caste composes the bulk of the ground military of the T’au Empire, and as such are the T’au most often encountered by the Imperium. They average as tall as or slightly shorter than an average Human, and are generally muscular. This comes from the Fire Caste’s origin on the plains of T’au, the T’au homeworld, where they survived as hunters and warriors. T’au from the world of Vior’la tend to have slightly greater muscle mass than is common among their species because of the increased gravity of Vior’la.
