Shas'O Vior'la Shovah Kais Mont'yr, often shortened to O'Shovah, but better known as Commander Farsight -- the "Hero of Vior'la," "Protege of Puretide," "The Bane of Greenskins," and even "Renounced Traitor to the Greater Good" -- is the renegade Fire Caste Tau Commander alleged to still be leading the breakaway Tau colony worlds known as the Farsight Enclaves in the Segmentum Ultima. There is no figure in Tau history as divisive as Farsight, for he is the most famous warrior to hail from the Tau world of Vior'la, as well as a protégé of the legendary Commander Puretide.
