During the battle of Dathomir, this Nightsister along with a fellow one were sent by Mother Talzin to recover an orb containing a lock of hair Count Dooku so she could use it to create a magical voodoo figurine likeness of Dooku, conducting her magic through it to torment the Dark Lord of the Sith into rescinding his attack or else suffering an agonizing death.
The Nightsisters succeeded in doing so, but General Grievous was then informed by Dooku to forget about Asajj Ventress and focus on Mother Talzin, so he attacked the Nightsisters fortress directly, killing Old Daka and this Nightsister, but failing to kill Talzin who managed to escape.
