Jen Garondel was a technician.
According to Ravus Oldeman, Garondel conducted a project on Akoshemon's moon, telling the scientists he enlisted that it was for improving long-term induced animal hibernation systems by genetic manipulation. In actuality, he believed the natives had long lifespans and hoped to find their secret. Instead, through the manipulation of the Dark the project created the Bloodhunter which eventually killed them all.
However, Tegan discovered that it was Oldeman who was in charge of the project, not Garondel. He falsified the project records to support his story about Garondel. (PROSE: Fear of the Dark)
