Episode 56: Nightsisters
Troubled by Asajj Ventress' growing prowess with the dark side of the Force, Darth Sidious commands Count Dooku to eliminate her. But Ventress survives Dooku's assassination attempt, and the jilted former apprentice vows to take revenge, enlisting the aid of her kinswomen -- the mystical Nightsisters -- in her sinister scheme.
As the space battle over Sullust ensues, Anakin and Obi-Wan find themselves fighting the Dark Warrior Asajj Ventress after crash-landing in the Separatist flagship. The fight is deadly but when the ship is fired upon by the other Separatist ships it ends as everyone scrambles for a ship to escape in.
