Hoctu, Drevveka
this woman was once a Jedi Knight, until she was consumed by the Dark Side of the Force many years before the Battle of Naboo. She ended up on Thule, and eventually became the headmaster of the Sith Arts Academy. She was known as a hard master, and drove her students into the deserts on long, relentless training sessions that taught them to rely on the Dark Side for strength. Despite her skills, though, Hoctu was never elevated in rank beyond headmaster, and she vowed one day to make her superiors pay for excluding her.
