Darth Contagio was a Sith Steward during the Second Confederate War in 10 NE. Originally born on Hill and trained by Darth Dominus on that planet, he was inducted into the New Sith Order after being discovered by Darth Atra on one of his travels.
Shortly after leaving on his assignment from Darth Atra, Contagio encountered Jedi Master Yux Tarm in Texas. He attacked Tarm and his group, maiming all but Tarm. A battle ensued between the two, with Tarm utilizing Vaapad against the young Sith Steward. During the battle, Contagio was slashed across the stomach and decapitated by Tarm, thus ending his life.
