Haeresis

Lord Haeresis was a Sith during Darth Krayt’s reign. He was born as Ias on Taris in 140 ABY. His family was murdered when he was young, so he became a pickpocket and lived on the lower levels as a labeled thief.

Ias was recruited by Darth Sicarum, who came to Taris one day, to join the One Sith. However, Ias, now proclaimed Darth Haeresis, left the One Sith soon before its collapses and went to Korriban to train new Sith for a new Order that was prophesied to surpass Darth Krayt’s Order.

While his master trained the Sith on Dark-side world, Haeresis would go out and hunt for other Force-sensitive individuals to join their Order. Though, when war broke out between the coalition of the Jedi and Sith Orders and Balen’s Galactic Empire, Haeresis went to the front line to command a portion of the Order’s army of Sith warriors.

After the war, he served as a Councilor on the Assembly of Powers, along with his two apprentices, Lord Priden and Lord Irus, until the Sith rose up and fought the Empire again. For a second time, Haeresis commanded a part of the Sith army. He was faced by a party of Force-hunter Venators in 196 ABY, an encounter he did not survive.
