Dukat, was a Cardassian military officer who served as Prefect of Bajor in the final years of the Bajoran Occupation. As the last person to hold the position, Dukat lost favor with Cardassian Central Command and fell into a downward spiral for several years. However, he became ruler of the Cardassian Union overnight after he negotiated Cardassia's entry into the Dominion. Following his defeat in Operation Return and the death of his beloved daughter, Ziyal, he suffered a complete mental breakdown and was captured by the Federation when they reclaimed DS9. He subsequently escaped, and became a disciple of the Pah-wraiths. Along with Kai Winn Adami, he attempted to release the Pah-wraiths into the Bajoran wormhole. Dukat was imprisoned in the Fire Caves with the Pah-wraiths after a fateful confrontation with the Emissary of the Prophets.
