Topa Su

Topa Su was a Jedi who turned to the dark side in 22 BBY under temptation of Dooku. He was reported dead by Donnelly E'Imaj after she was shot and hurtled into the ocean below Tipoca City on Kamino. He in fact survived that fall and swam back up. He exiled in Kamino near the Razor Reefs. He decided to fly to Coruscant and secretly enter the Jedi Temple. He entered the Jedi Archives and began studying. E'Imaj approached him and sarcastically said, "are you not supposed to be dead?" Su stood up to E'Imaj pretending to be a Kaminoan Padawan trainee Jedi. E'Imaj left but reported this to Mace Windu. Su reappeared a few days later but E'Imaj stabbed him in the back outside the temple and secretly hid his body in an unknown place.
