Xinishia, a Tarasin female, belonged to the Wyrd, a coven of Force-sensitive witches active on the planet of Cularin in the final years of the Galactic Republic.
Xinishia served as one of Liriana's lieutenants, who was the leader of the Wyrd. As Liriana journeyed away from the planet during the Clone Wars, Xinishia saw Liriana's departure as an opportunity to seize control of the Wyrd for herself. She located a dark side relic that amplified her Force abilities. Xinishia then schemed to trigger an eruption of Cloud Mountain, a dormant volcano, to obliterate the village of Kiirloor. Nonetheless, the heroes of Cularin intervened to thwart her plans.
