A witch of the Sith order, and of female persuasion, took part in the Sith rebellion in conjunction with the dark lord. This witch used her powers to reanimate the dead before they could become one with the Force, forcing them to fight for the Sith as part of a Sith demons army. The dark lord then betrayed the witch, abandoned the Sith ways, and took on the mantle of the Ronin.
The Sith witch eventually gave birth to a daughter named Mirahi, whose father was the Ronin. However, the child was not raised by either of them; the Ronin was ignorant of her birth, and the witch had merged her being with the planet of Rei'izu.
Tales circulated that the Sith witch remained a force to be reckoned with even after the Sith rebellion, existing in that time period. The stories said that battlefields were left barren of corpses because of the witch's dark magic.
