Kai Saddek was a Human male Assassin who served House Rist during the Cold War between the Galactic Republic and the resurgent Sith Empire. He and Sam Saddek threatened to divulge secrets once held between House Rist and the House of Thul, to provoke the Empire into sending a emissary to take hostage. He engaged an Imperial individual and was easily defeated. Deciding the evidence was not worth their lives, Sam betrayed his brother, revealing the evidence was on its way to House Ulgo, before knocking Kai unconscious.
