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.
Mother Talzin, the spiritual guide of Dathomir's Nightsisters during the Clone Wars, held enormous power on her homeworld and wielded the strange magicks of the Nightsisters. She sold the services of the Nightsisters to the galaxy's wealthy and powerful, but wasn't above backstabbing any clients who treated her clan with disrespect. She sought revenge against Count Dooku and his master, Darth Sidious. Dooku had betrayed the Nightsister Asajj Ventress, but his crimes paled in comparison with Sidious’s. Long before the Clone Wars, Sidious had promised to make Talzin his right hand, only to renege on his promise and steal her son, Darth Maul, to train as his apprentice.
General Grievous was a brilliant Separatist military strategist and a feared Jedi hunter, known for his ruthlessness and hacking cough. His body itself was a weapon, allowing him lightning quick strikes and devastating blows. But he was also quick to run from a fight, a tactic that worked until one final meeting with Obi-Wan Kenobi.
A remote planet, Dathomir is drenched in blood-red light from its central star. The planet has continents overrun by twisted vegetation, with forests of bent trees burdened by large, cocoon-like fruit. Bordering dense swamplands is the massive stone fortresses of the Nightsisters, a witch clan. The Nightsisters kept to themselves, but had on occasion been known to offer their services to those who piqued their interests. Far from the Nightsisters lived the Nightbrothers -- a tattooed clan of Zabrak warriors were subservient to their female counterparts.
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.
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.
