Niniane
Force user trained in artificer powers by someone, possibly Mira.
Responsible for the deactivation of the shield around Nal Hutta
Orchistrated the kidnapping of Aenea based on information provided by the group to the council. She was working with certain council members (Peace, Knowledge, the-other-bothan) on the Exordium project.
Using the Rhelta, a Sith deep infiltrator cap ship, she arranged for the construction of a massive force amplifier so she could tap into the broadcasts from the future in order to fight the Dark Swarm with new weapons.
When the Misfits confronted the council with her actions and the conspiracy within their midst, she arrived late along with Altair T'nol right before a concealed force explosive detonated and harmed most of the council. This implies she may have been complicit in the assassination of the former head of the coucil, as Altair and Zeltar share one body with two Resurrection Parasites. To the best of the group's knowledge, she does not have a r.p.
In the subsequent armed conflict, she would have been killed if Evika hadn't saved her. This allowed her to aid the currently-living coucil members against the attack by the dark swarm. She had two figher craft which were armed with exotic munitions, and these allowed the jedi to mount a counter-offensive.
She was under house arrest on Nubia where she was continuing (hopeully) supervised research into combatting the dark swarm. However, when the Swarm took down Nubia, she was able to regain some of her influence and is a major power center in the newest incarnation of the Jedi Order, or at least an element of it. She appeared? above Enatia and participated in the battle for the Jovian Super-Station?. She was persuaded not to activate the station in the manner suggested by the Shadows due to the actions of the misfits, and as they were leaving the station, it was revealed to Quindo that the woman known presently as Niniane was in fact the Dark Jedi who was his father, having taken over his mother's body when escaping Nal Hutta.
