Nidell was a Halanan female and the last wife of noted terraformer Gideon Seyetik. Her species have an unusual ability known as psychoprojective telepathy. Nidell lost control of hers, creating an alter ego, Fenna. This alter ego met and fell in love with Benjamin Sisko. When Sisko met Nidell at Seyetik's home, he at first thought it was Fenna. Seyetik later explained his wife's telepathic ability.

The Halanan project these alter egos when they are under great stress and can die from the experience. In order to save Nidell, Seyetik killed himself by flying a shuttle into the sun. She recovered and did not remember her experiences as Fenna. (DS9: "Second Sight")

Nidell was played by actress Salli Elise Richardson, just like her alter ego, Fenna.
