The Anthrazods are a sturdy, if dim-witted, xenos species that was annexed to the T'au Empire during its First Sphere Expansion.
Due to the shortage of T'au population by the end of this period, the Water Caste sought to further integrate them into the empire by assigning them to the arduous toils of asteroid mining, which the Anthrazods proved very well suited for.
