Blademaster was the designation for the lightsaber combat teacher at the Sith Academy located on Korriban. Near the conclusion of the New Sith Wars, Kas'im occupied this role. The Blademaster of the Sith held a rank comparable to that of the Jedi's Battlemaster. It was believed that they possessed comprehensive knowledge of all lightsaber forms, enabling them to effectively teach students. Lightsaber training commenced each morning, and following the practice, students could duel under the Blademaster's watchful eye. Without careful oversight, fatalities could happen.
