The Mont'au is the term in the Tau Lexicon that literally translates into the Low Gothic language of Mankind as "the terror." The term refers to the dark and violent time before the Ethereal Caste arose in Tau society to unite all the castes of the Tau behind the concept of the Greater Good. In more recent times, the term has come to be the way the Tau refer to the Forces of Chaos in the Tau Lexicon. The Tau have learned the hard way, like the Imperium of Man before them, that the Greater Good has no meaning to the servants of the Ruinous Powers, who care only for the destruction of all that the Tau Empire has sought to build.
