The haut Nadina was consort for Sigma Ceta during the time of the theft of the Great Key of the Star Crèche. She was taken prisoner by her haut governor, Ilsum Kety, when the haut ladies tried to recall their gene banks (without which the Great Key would be useless). Miles Vorkosigan and haut Pel Navarr came to her rescue; she helped by leading them to the room where the Key was being kept.
