Injured during the Battle of Sullust, Asajj Ventress hijacks a ship and escapes to her homeworld of Dathomir. Initially not recognized by the Nightsisters, they confront her -- until Mother Talzin arrives.
Asajj Ventress returns from the Nightbrother village with Savage Opress, their finest male warrior. Mother Talzin, impressed with his physical prowess, will enhance his abilities with Nightsister magic.
Seeking revenge on Count Dooku after he left her to die, Asajj Ventress goes to Mother Talzin for help. Using Nightsister magic, Talzin gives Asajj and her accomplices an invisibility potion and poison darts to aid in their assassination attempt.
FALL OF THE REPUBLIC
The matriarch of Dathomir’s eldritch Nightsisters, Mother Talzin was a Force witch with enormous powers and a mysterious past. She had once been an ally of Darth Sidious and Count Dooku, but now worked to gain revenge on both of them.
Talzin used her magic to turn the Nightbrother Savage Opress into a massive dark-side warrior, presenting him to Dooku as an apprentice to replace Asajj Ventress. In reality, Savage was her creature, a pawn in her plan to kill Dooku and so avenge his betrayal of Ventress.
The plan failed, but Savage had another, more important role to play: find Talzin’s son Darth Maul, whom Darth Sidious had stolen from her long ago. By restoring Maul’s powers, Talzin hoped to defeat Sidious and become the most powerful being in the galaxy.
The Nightsisters are a coven of witches that lived on the mysterious world of Dathomir. The sisters ruled unchallenged, gifted with the power to wield dark magicks. The men of Dathomir, the Nightbrothers, lived apart from the witches, but were subservient to their whims. Despite their power, the Nightsisters avoided the conflict of the Republic and Sith, content to pursue their own matters. The Jedi gave them a wide berth, for they remain focused on matters on Dathomir. Count Dooku has had dealings with them in the past, and turned to them when he was in need of a new apprentice. Their betrayal of Dooku earned the Nightsisters a powerful enemy, and he ordered a massive attack by his droid forces in retribution.
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.
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.
Savage Opress was once a common Nightbrother whose fighting prowess impressed Asajj Ventress. Transformed into a monstrous warrior by Mother Talzin, Opress became Count Dooku's new assassin and secret Sith apprentice. His loyalty, however, remained to Talzin. The Nightsisters leader gave Savage a new quest: to find his brother, Darth Maul, who had somehow survived his apparent death and was living in exile in the Outer Rim. Savage located Maul and became his brother’s enforcer in the Shadow Collective, but died when Darth Sidious confronted the two Sith warriors on Mandalore.
A deadly, agile Sith Lord trained by the evil Darth Sidious, Darth Maul was a formidable warrior and scheming mastermind. He wielded an intimidating double-bladed lightsaber and fought with a menacing ferocity. Though he fell in battle against Obi-Wan Kenobi, the Zabrak from Dathomir would prove to be much harder to destroy than originally believed.
The oldest and wisest of the Nightsisters clan, Old Daka's knowledge of the arcane magicks was unprecedented. When the Separatists launched a devastating attack on Dathomir, and the Nightsisters were outnumbered by General Grievous's droid forces, Mother Talzin retreated into the depths of the witches' lair and called upon Old Daka for help. Daka used an ancient incantation to summon the dead from the Nightsisters' graveyard, bolstering their number with zombie hordes.
