Count Dooku was a menacing Sith Lord and central figure in the Clone Wars. Once a Jedi -- trained by Yoda -- he became disillusioned with the Jedi Order and thirsted for greater power. Dooku voluntarily left the light side behind and became Darth Sidious’ dark side disciple, taking the secret name Darth Tyranus and leading the Separatist army. Dooku advanced Sidious’s secret plot to take over the galaxy, but forgot that betrayal is the nature of the Sith.
An ancient order of Force-wielders devoted to the dark side, the Sith practice hate, deception, and greed. Notable for their red-bladed lightsabers, black dress, and use of their aggressive feelings, the Sith look to amass power at all costs. The evil Darth Sidious, along with his apprentice Darth Vader, achieved the Sith goal of galactic conquest after a millennia of plotting.
Discovered as a slave on Tatooine by Qui-Gon Jinn and Obi-Wan Kenobi, Anakin Skywalker had the potential to become one of the most powerful Jedi ever, and was believed by some to be the prophesied Chosen One who would bring balance to the Force. A hero of the Clone Wars, Anakin was caring and compassionate, but also had a fear of loss that would prove to be his downfall.
An assassin trained in the ways of the dark side by Count Dooku, Asajj Ventress yearned to be considered a true Sith, but such status wasn't allowed under the Sith's Rule of Two. Ventress fought with twin red-bladed lightsabers, and clashed with Obi-Wan Kenobi and Anakin Skywalker many times. But her destiny would not lie with the Sith. After Dooku rejected her as his apprentice and tried to kill her, Ventress returned to her roots as a Nightsister, made a living as a bounty hunter, and – in the strangest twist of all – rediscovered the way of the light that she’d rejected long ago as a Jedi Padawan.
