Shas'O Tiro'fal Seroshal Kais M'yen(Commander Shadowsword) is a legendary figure amongst the Tau of the Tiro'fal Sept, famed throughout the empire for his repeated use of successful unorthodox tactics for which his sept is well known. His repeated successes have been so well documented that rumours have developed that he may be one of the legendary students of Commander Puretide, even if the Sept's history indicates otherwise. In his service Shadowsword has combated the enemies of the Tau Empire repeatedly, having waged war against the Orks and Chaos Space Marines to name just some.
