When revan arived to Korriban, he had to enter the Sith Academy in order to find one of the Star Maps that led to the Star Forge. One of the rooms in the Academy was the Sith training room. In here, the Sith held republic captives, and a Sith apprentice would be able to fight, and kill a captured Republic soldier at any time. Revan had the possibility to fight, and kill the captured republic soldiers, (non-canonical).
