Kamden, a Twi'lek of the male persuasion, held the rank of Major in the Galactic Republic's Special Forces Division. During the Galactic War, he was stationed on Taris, where he commanded some of the remaining Republic forces in the battles that transpired after the Sith Empire launched their Invasion of Taris. Lieutenant Trell characterized him as "shrewd" and noted that his significant cybernetic augmentations made him particularly formidable.
Although Major Kamden is referenced in the "Taris: Bonus Series" quest line for the Imperial faction within the Star Wars: The Old Republic MMORPG, he is never visually represented in the game. However, the game's data includes him as a non-player character (NPC) in the final quest, "Secret Intentions," suggesting that this quest was ultimately removed from the game. These very files are the source of information regarding his species and physical characteristics.
The player character would have likely been assigned the task of tracking down Major Kamden after commandeering a Republic speeder, however, this final quest was removed from the game. Therefore, any potential death of Kamden is not considered part of the official Star Wars canon.
