Argos

A Human male with pale skin, orange eyes, and gray-brown hair cut close in a striped pattern, Argos had achieved the rank of Sith Lord in the resurgent Empire by the year 3640 BBY. Argos was proficient in the use of Force blasts and lightning in conjunction with their red-bladed lightsaber, and they wore a respirator mask and armored robes in combat.

As the Galactic War broke out with the Galactic Republic, Argos was sent to the planet Corellia under the Sith Emperor's servant, the corrupted Jedi Master Tol Braga. There, as the Battle of Corellia raged across the world, Argos and several Sith Masters were sent to the Saxan Chemical Refinery accompanied by over a dozen Sith assassins and warriors in order to create a chemical bomb that would kill millions. However, the Jedi Knight known as the Hero of Tython attacked the refinery in order to stop the Sith, and Argos was killed by the Knight during the battle.
