High Command Base was the installation where the Alliance High Command was based. The location moved throughout the Galactic Civil War. The original base was located on Chrellis, but was forced to relocate when an Imperial Sector Fleet began operating nearby. The base moved to Brigia, Orion IV, Dantooine, and Yavin 4.
