Thorsh was a male Jenet operating as a scout and reconnaissance agent in the Galactic Alliance military during the Yuuzhan Vong War, on Duro and Gyndine among other worlds. Thorsh participated in Operation Trinity over Bilbringi, and was among the military personnel captured there by the Yuuzhan Vong. He was incarcerated on Selvaris along with Pash Cracken and Judder Page. When the informant known as Ryn 115 provided the captives with data concerning Yuuzhan Vong operations, Thorsh memorized the encoded data and, along with three Bith prisoners, managed to escape from the prison camp to waiting speeder bikes.
