What is known suggests that Khonsu II is a dynamic and able leader. His first action of record was the dissolution of the Parliament of Vasuda following the 14-Year-War and Great War. He is primarily credited with the Vasudan recovery and expansion during the Reconstruction, and the creation of the GTVA.
Khonsu's term of office is unknown, though at the time of Freespace 2 he has undoubtedly been in power for at least a generation. Whether he was Emperor during the 14-Year-War or Great War is unknown, though presumably the term "Parliamentary Vasudan Empire" suggests there was an emperor.
