The Alliance High Command made its headquarters at High Command Base. This installation's location shifted during the course of the Galactic Civil War. Initially, the base was situated on Chrellis, but it had to be moved when an Imperial Sector Fleet started operations in the vicinity. Subsequent locations included Brigia, Orion IV, Dantooine, and Yavin 4.
