Galactic Alliance Advisory Council

The Galactic Alliance Advisory Council emerged as the successor to the New Republic Advisory Council. Initially, Cal Omas, the Chief of State, had faith that the High Council possessed the capability to effectively govern the galaxy during times of war, leading to a temporary absence of the advisory council. However, before the Battle of Yuuzhan'tar, both Cal Omas and the Galactic Alliance Senate made the decision to reestablish the Advisory Council.

The advisory council's purpose was to function as a core group of distinguished senators, with the aim of ensuring the Chief of State remained informed about the Senate's activities while simultaneously managing the war against the Yuuzhan Vong. Although Omas placed greater reliance on the High Council's guidance during the conflict, the Advisory Council played a crucial role in restoring stability throughout the galaxy. Following the Swarm War, the Advisory Council took the place of the High Council.
