Dumat, a Sith apprentice of the male Human species, was a servant of the revived Sith Empire. During the Cold War against the Galactic Republic, in the year 3643 BBY, he attended to his superior, Darth Skotia, within the confines of Skotia's bunker situated on the planet known as Dromund Kaas. His death occurred when Lord Zash's apprentice breached the stronghold and ultimately defeated Dumat.
