Nightsisters

The Nightsisters was both a clan and an order of Force-wielding females who lived on Dathomir, a planet bathed in dark energies. By tapping into the magical ichor of that flowed from Dathomir's depths, they could use their arcane magicks.

Religion and Philosophy
By tapping into the magical ichor of that flowed from Dathomir's depths, the witches could harness a power they referred to as "magicks." The most powerful of them could use that ichor to summon objects out of the thin air, transform people into ghostly versions of their true forms, or even reanimate the dead. These witches adopted a shamanistic culture that rejected the notion of "good" and "evil", and instead chose to call upon the twin energies of the Winged Goddess and the Fanged God in order to utilize their Magicks and communicate with the spirit realm.

Society and Culture
The Nighsisters lived in the seclusion of a stone fortress that bordered dense swamplands. A matriarchal society, the coven of sisters had the men of Dathomir, the Nightbrothers, living apart from them. Those males were only kept as servants and breeders. They used to mummify their dead before placing them in pods of animal skin decorated with tassels. Those pods were hung to structures made of branches, bones, animal skins and shells. Their graveyards mimicked the configuration of the plant life seen on Dathomir, with its crooked trees burdened by large, cocoon-like fruits.

History
The Nightsisters' clan developed on the mysterious planet of Dathomir. Since they were most powerful on their home planet, they rarely ventured off-world during the height of the Galactic Republic. However, that situation changed when a sister named Talzin became the clan's Mother. At the time of the Clone Wars, Talzin started to sell her sisters' services as mercenaries to the galaxy's wealthy citizens.

At some point prior to the Clone Wars, the clan was forced to give up the young Asajj Ventress to the Siniteen criminal Hal'Sted as protection. Ventress would later return to her people after being betrayed by Count Dooku and sought their help for revenge against her former master. Mother Talzin healed Ventress with her magic which caused her to sleep. Upon awakening, she swears an oath of revenge against her former master; Mother Talzin puts two of her finest warriors, Naa'leth and Karis, to assist her and provides her with the means of approaching and combating Dooku with the help of mystical invisibility potions and poisons. The assassination failed, But Talzin is content: With this attempt at his life, she reckons that Dooku will now be more anxious to get himself a new assassin and bodyguard to protect him. As a result, she contacts the Count and suggests a replacement – a male Zabrak warrior from her people – an offer Dooku decides to take.

The Nightsisters then formed a scheme to give Dooku an apprentice but be loyal only to the witches. Asajj held a test of the Nightbrothers to see who was worthy of being her champion. She choose a Zabrak called Savage Opress and brought him back to the fortress. Back in their abbey, the Nightsisters use their mystical powers to increase Savage's strength and ferocity, turning him into a hulking brute, and putting him under Ventress' complete control and gave him to Dooku.

When Savage killed two Jedi, Master Obi-Wan Kenobi and Jedi Knight Anakin Skywalker went to the planet Dathomir to investigate. They went to the Nightsister village only for them to be disarmed and brought inside the fortress to speak with Mother Talzin. Talzin initially denied she had any knowledge of Savage's whereabouts, but relented after prodding by Kenobi, using her crystal ball to inform the Jedi he was on Toydaria. After they left in earnest, Talzin met with Ventress and told her that the time to put her plot in motion had come—she would have to confront the Count herself with Savage's aid. While Ventress believed Opress needed more training, Talzin assured her that he was indeed ready and they could not keep him secret for much longer. Later a battle-weary Savage returned, having broken away from his loyalty to Ventress and having escaped from both her and the Jedi. Talzin helped him to his feet and told him she would help him obtain the power he needed. She sent him on a quest to find his brother who was hiding in exile in the Outer Rim, with the aid of a special talisman.

Ventress later returned to Dathomir and Talzin and the Nightsisters welcomed her back with opened arms. Talzin recommends that Ventress should cast off her ambitions to become a Sith and fully reintegrate herself in the ranks of the Nightsisters. Ventress agrees and undergoes the initiation ritual, becoming a fully accepted member of the order once again. Unknown to them, Dooku had harbored revenge against the traitor Ventress and the witch Talzin and he commanded General Grievous to proceed to Dathomir and eradicate the Nightsisters. The droid forces descend upon the initiation festivity in full force, and the Nightsisters prepare for battle. The Nightsisters begin to mount a counterattack under Ventress’ leadership, but as soon as Ventress appears on the battle field, Grievous sends out a group of defoliator tanks to wipe out their opponents with one stroke. Ventress manages to destroy the defoliators and fights her way right up to Grievous, challenging him to single combat, which Grievous readily agrees to.

During the battle, Mother Talzin calls upon her order’s venerable elder, Old Daka, to allow the reviving of the past Nightsisters with their dark magic, thus creating an army of the dead to repel the Separatists. Old Daka casts forth her power, and the remains of the dead rise from their burial pods and join their living sisters. While Talzin used a lock of Dooku’s hair she had previously taken and stashed away in secret; using it to create a magical voodoo figurine likeness of Dooku, she conducts her magic through it to torment him into rescinding his attack or else suffer an agonizing death.

During the duel Ventress defeated Grievous but still ordered his droids to attack. Dooku, feeling the pain of the Nightsister magic, ordered Grievous to kill Talzin and to follow the witch's magic as it appears as green mist. Grievous then tracks down the origin of Talzin and Daka’s magic. He first kills Daka, disrupting the resurrection magic, and without reinforcements the remnants of the Nightsisters are helplessly slaughtered. Before she can be executed by Grievous, Talzin turns into smoke and vanishes.

The Nightsisters were all killed and their order ruined, but Mother Talzin still lived to continue on her Nightsister ways. She stilled lived in the ruins of the Nightsister fortress and watched Savage's journey to find his brother through magic globes made of spirit ichor. She foresaw that he would find his brother and she must make the necessary preparations for their arrival.

Savage returned with his brother, the Sith Lord Darth Maul to Dathomir. Savage saw the carnage of the battle and the dead Nightsisters laying around until Mother Talzin appeared to him in wisps of green mist. Savage questioned what happened to the Sisters and Talzin responded they were wiped out, but she assured him that they would survive as they always have. Mother Talzin then lured Maul out with her magic and then led to her village, where she removes Maul's spider-like cybernetics and uses magicks to create new cybernetics, as well as restore Maul’s sanity. When her work was done, she vanished once again,[9] leaving Maul and Savage to begin forming an army with which they could rival Talzin's enemy Darth Sidious.

Powers and Abilities
The Nightsisters magic was called Spirit ichor was the base for all magic employed by the Nightsisters of Dathomir during the Clone Wars. According to Mother Talzin, it came from channeling the Winged Goddess and was manifested as green smoke. Spirit ichor could be manipulated in a large variety of ways by a shaman. A shaman could manipulate spirit ichor into physical objects such as a goblet of blackroot, as Mother Talzin did for Count Dooku when he visited Dathomir during the Clone Wars. Mother Talzin was also seen later to conjure a Lightsaber in order to combat Jedi Master Mace Windu. Spirit ichor could also be used for divination; for mesmerism, to induce a victim into a trancelike state; for totem magic; or to conjure the Water of Life for healing purposes and other uses.

As Mother Talzin did for Asajj Ventress, Naa'leth, and Karis, spirit ichor could be manipulated to produce a luminescent green mist that allowed assassins to operate "midway" between the physical and spirit realms, cloaking them with near-invisibility. Savage Opress was also transformed into an avatar of primal anger by Talzin and a coven of spellcasters via spirit ichor. The Nightsister clan had used their magicks to enhance Savage Opress's features: longer horns, taller, and larger physique, turning him into an avatar of primal anger. Talzin later used her magicks to cure Darth Maul of his insanity and grant him prosthetic legs. The Witches also used a magical potion called the Water of Life, or the waters of life, and it was an employment of spirit ichor that was used by the Nightsisters of Dathomir in their spells. It was used primarily for healing purposes but could also be used to render someone near-invisible.

The Nightisisters also used a type of hypnotic spell called Mesmerism and it was a Nightsister technique, provided by spirit ichor. This power allowed a shaman to override the thought of those weaker than oneself, particularly men and offworlders. A tap of the fingertip to the victim's forehead would induce a trancelike state and make the victim powerless to refuse commands.

One final act of magic that could only be used by an experienced elder Nightsister was called the Chant of Resurrection. The Chant of Resurrection was a powerful dark spell of Dathomir Magic that could temporarily resurrect the dead, so long as the caster remained active. Old Daka, the oldest of the Nightsisters, used this spell to reanimate the mummified corpses of deceased Nightsisters to bolster Asajj Ventress's army during the Battle of Dathomir. Once Daka was killed by General Grievous, the spell wore off immediately, and the dead returned to their natural state.

Like all Nightsister magicks, the spell appeared as a green mist.
