Kayana Gundar was a female Cardassian.
Gundar was a member of the Obsidian Order. In 2364, Gundar was assigned to a deep cover intelligence assignment by the Obsidian Order and all records of her vanished. In 2366, Kira Nerys and Kira Reon thought Kayana might have been surgically altered to resemble Plin Teara and had assumed Plin's Bajoran identity.
