A female Sith witch participated in the Sith rebellion alongside the dark lord. The witch resurrected the dead before they could join the Force, making them fight for the Sith in an army of Sith demons. The dark lord betrayed the witch, renounced the Sith, and became known as the Ronin.
At some point, the Sith witch gave birth to a daughter, Mirahi, who was fathered by the Ronin. However, neither parent raised their child; the Ronin was not aware of her existence, and the witch had joined herself with the planet Rei'izu.
The Sith witch was rumored to be active in the time after the Sith rebellion. According to the tales, battlefields would no longer leave bodies due to the witch's sorcery.
