Elani was a female Vorta in service of the Dominion. During the Dominion War, the Founders sent Elani to stop a renegade Changeling, who had assumed the guises of Starfleet officer Andrew Ellis and Maquis member Arak Katal, by taking away his shapeshifting abilities. Condemned by the Changeling for doing so, Elani took her own life by activating her termination implant. (VOY - Spirit Walk novel: Enemy of My Enemy)
