Sansizia Chreet was a female human codebreaker who served as a droid trainer at Ralakili's Droid fighting pits at The Lodge on the planet Vandor. She was hired by Ralakili to bypass the safety protocols on droids to turn them into fighting machines. He also had Chreet construct restraining bolts with remote triggers that were used to shock droids whenever the trigger was pressed. In addition to making technical modifications to droids, Chreet was tasked with repairing any damage after battle.
