Shendan was a Sith Lord of the Human race, identified as male, who was a member of the reconstituted Sith Empire during the era known as the Cold War.
In approximately 3640 BBY, Shendan was dispatched to the world of Voss with the mission of assassinating Gaden-Ko, his goal was to persuade the Voss people to align with the Empire. Seizing an opportunity, he stabbed Gaden-Ko, but the Jedi Consular intervened, thwarting the assassination. The Consular gained the advantage in the fight, leaving Shendan severely injured. Shendan, impressed by the Jedi's strength and on the verge of death, was spared. Instead of ending his life, the Jedi Consular sought to redeem him, encouraging him to relinquish his hatred and embrace the purity of the light side. Experiencing calmness for the first time, Shendan passed away peacefully.
