Indava was a Triannon female serving under Pri'Nam D'Jamat. She was married to Yarrick and was a member of his group on a pilgrimage to the 12th sphere in their ship.
Indava grew to hate her faith while serving under the fanatical D'Jamat; when Triannon forces occupied Enterprise NX-01, she approached Doctor Phlox and asked him to terminate her pregnancy. She did not want her unborn child to become another foot soldier in D'Jamat's endless religious war.
She assisted Captain Jonathan Archer in retaking Enterprise from D'Jamat and fired on a Triannon who was about to kill MACO Private S. Money in a corridor.
After the incident was over, she descended to Triannon in Shuttlepod 2, and witnessed the devastated planetscape of her homeworld. (ENT: "Chosen Realm")
