Tobar Ka-Teen was a male Jedi Master of the Ithorian species who dedicated himself to the service of both the Jedi Order and the Galactic Republic throughout the Clone Wars. Not long after his promotion to the rank of Jedi Master, Ka-Teen was taken prisoner by Kallyx the Piner, a bounty hunter working for Black Sun, and endured torture for a number of weeks. Throughout this time, Master Ka-Teen constructed an intricate network of falsehoods and successfully engaged in lying, an action he previously believed himself incapable of. Ultimately, Ka-Teen was liberated by his fellow Jedi, after which he became withdrawn.
While stationed at the Jedi Temple located on Coruscant, Master Ka-Teen developed a strong interest in the Crown of Verity, a unique artifact possessing the ability to identify any falsehood and, conversely, compel its wearer to consistently speak the truth. During the Clone Wars, while in possession of the crown, Ka-Teen sensed a powerful vergence on the planet Auratera. Despite not holding the rank of Jedi General, Ka-Teen was accompanied by multiple squads of clone troopers. It was during this time that Order 66 was executed against the Jedi Order, leading to the presumption that Ka-Teen had been killed, with no evidence to suggest his survival. However, the troopers who went with him never came back.
