Tora Naprem

Tora Naprem was a Bajoran woman in the Occupation of Bajor. She became Prefect Gul Skrain G. Dukat's mistress, and over time, truely felt feelings for him. This relationship bloomed to the point where Naprem became pregnant and gave birth to Dukat's Half-Bajoran/Half-Cardassian daughter, who they named Tora Ziyal.

Near the end of the Occupation, Dukat realised he could not protect his Bajoran family as his enemies would use them to ruin his career. So instead, he arranged for Naprem and Ziyla to travel on the Ravinok, where they would reandezvous with a freighter which would take them to Lissepia, where she and Ziyal could live out their lives in peace. This plan was undone, however, when 2 Breen Warships attacked the Ravinok and forced it to crash on a planet. Naprem died in the crash. (DS9: Indiscretion)

Naprem was replaced as Dukat's mistress by Cerin Mika, who Dukat raped as he found her attractive. Though this relationship only lasted one evening, it was still enough to get Mika pregnant with Dukat's second illegitamite Half-Bajoran/Half-Cardassian daughter; Cerin Teresa, as Ziyal had since died.
