Darth Rage was a male Human Sith Lord. Darth Rage took part in the First Jedi Purge and was the Sith who killed Rieeko Zako, Tishec Zako's adopted father. Soon afterward, Tishec went to Korriban in search of teaching of the Sith. He was met by Darth Zorune, who was one of the teachers in one of the academies. Zorune appointed Tishec to Darth Rage.
After several months of training, Tishec challenged Rage for supremacy and a duel ensued. However, Rage underestimated Tishec and was killed. After he died, Tishec left Korriban to seek work that did not ally him with any major faction.
