During 3643 BBY Overseer Tremel had send a promising young Sith Warrior to Knash's prison cells with a mission to interrogate several prisoners, including Solentz for any useful information they might have had. Knash was informed of the Warrior's arrival, who witnessed Knash used a shock collar on the Twi'lek slave girl Vette for her annoyance. Knash introduced the Warrior to three prisoners and guided him through the interrogation, leaving him to decide their fates and reporting to Tremel on the results. Later, Knash released Vette to assist the Warrior in breaching the Tomb of Naga Sadow for the final trials.
