Prefect was a common title denoting authority. It was used across the breadth of the galaxy for various officials. The Yuuzhan Vong also employed this title, and even had a position called High Prefect. Da'Gara of the Yuuzhan Vong is one such example of a prefect. Prefects among the Yuuzhan Vong served in the roles of governors of planets and as leaders of their massive worldships.
