Krimyn, a Twi'lek male, held the title of Sith Lord and was a member of the Sith Empire throughout the era known as the Cold War. His role involved imparting sophisticated training techniques to Sith Warriors.
Krimyn's character was featured in the video game Star Wars: The Old Republic. Within the game, he functioned as the specialized instructor for the Sith Warrior class. Players, dispatched by Lord Lokar, would seek him out to acquire the necessary skills to become either a Sith Juggernaut or a Sith Marauder. His presence was discontinued with Game Update 5.0, which made advanced classes accessible during character creation, eliminating the need to reach level 10 for specialization.
