The main structure of the Vishtu Sector was the Vishtu command enclave. This building was situated on Coruscant following its transformation into Yuuzhan'tar by the Yuuzhan Vong. Within its walls were the primary administrative areas for Prefect Ash'ett, alongside the offices of other important Intendants. A swarbrik protected the enclave, but it was in poor health—constantly bleeding—by the time Priestess Ngaaluh arrived to look into Ash'ett's activities. This was yet another indication of the World Brain's decline.
