The wife of the Vaadwaur survivor Gedrin, who entered stasis beside him during the destruction of their homeworld and is found in 2376 not to have survived the nine centuries of sleep.
Jisa appears briefly in the sixth-season Voyager episode Dragon's Teeth, played by Mimi Craven. In the opening scenes, set some nine hundred years earlier, she and her husband Gedrin hurry into an underground chamber as their city is bombarded from orbit and seal themselves in stasis pods, expecting to wake in five years.
When Voyager's away team explores the ruins, Seven of Nine revives Gedrin without waiting for orders. His first thought is for Jisa, but her pod has failed and she cannot be saved.
Her death shapes Gedrin's part in the story. Grieving, and with no one left to share the future his commanders are planning, he is the one Vaadwaur prepared to admit his people's past to Captain Janeway and finally to help Voyager against them.
