Jenza

Jenza was a Serennian woman, the child of Count Gora and Countess Anya, and the sibling of Dooku and Ramil, who was younger than them. Because Dooku showed sensitivity to the Force, Gora relinquished him to the care of the Jedi Order, where he became a Jedi initiate. During a festival, Dooku, along with other initiates, made his way back to Serenno where he met Jenza and learned of their familial connection. Jenza and Dooku maintained a clandestine correspondence after he went back to the Jedi Temple located on Coruscant. Lady Jenza was abducted by agents supported by the Republic, so Dooku gave Asajj Ventress, his apprentice, the mission of finding her. Unbeknownst to Ventress, Dooku's true objective was for her to act as his assassin and murder his sister, as Jenza intended to disclose Dooku's secrets to the Republic, thereby ending his connection to his previous life. Jenza implored Dooku to reach out to the Jedi and to forsake his descent into darkness, but Dooku remained resolute and instructed Ventress to kill her.
