Lord Tagriss was a male Sith Lord of the Sith Empire who at one point during the Galactic War pledged his loyalty to the Dread Masters. For his new masters, Tagriss guided the Dread Guard in a raid to the Arcanum, a Sith secret deposit of prohibited lore, and here took many terrible objects, among them the Seeds of Rage that Tagriss used to create fear on many planets. However, he was pursued by task forces from both the Sith Empire and the Galactic Republic, and in the end one of them defeated him in a base on Ilum.
