Nisotsa

Nisotsa was a female Human Jedi apprentice who lived in the time of the Mandalorian Wars and the Jedi Civil War. She was a friend of Galir Tartuo when they were still apprentices. After the Mandalorian Wars ended, she fell to the dark side along with Malak and Revan and began fighting against the Republic.

Biography
During a gathering called by then-Jedi Malak in 3,965 BBY, Malak made a great plea to his fellow Jedi to follow Revan and him to war against the Mandalorian threat.

Nisotsa ended up casting her lot in with the rogue Knights, going against the High Council's wishes, and by doing so, helped to split the Jedi Order in two.

She was also one of the rogue Jedi to join Revan's new Sith empire. Nisotsa served as a Dark Jedi foot soldier for several years, until Darth Malak called her to a "meeting" on the Leviathan. At the "meeting", Nisotsa herself was imprisoned and slashed in half in order to turn Galir Tartuo to the dark side.

As a Jedi, she wielded a yellow lightsaber.
