Duenna Damajina was a librarian and the daughter of the Federation Chairman.
She and Keri discovered the location of the Ancient Diadem and went on an expedition to find it. She put her research on a storage disc.
Later pursued by thieves who wanted the information on the disc, she evaded them long enough to get a library and send the data she collected back home. Her lover Alec Roberts found her there and revealed he had been using her to help find the Diadem. He then killed her, but not before she could destroy the disc and prevent Roberts from obtaining the information. (PROSE: Legacy)
