Members of the Fire caste are the warriors of the [[Tau Empire]], and as such are most often seen on the field of battle. They are taller and stronger than the members of the other castes, although still weaker and shorter than the average human. These traits come from the Fire Caste's origin on the plains of T'au, where they were hunters and warriors. Tau from the world of [[Vior'la]] tend to have slighter slightly greater muscle mass than the norm because of the stronger gravity of that planet. These warriors are known as [[Fire Warrior]]s.
