The High Council building served as the meeting place for the High Council of Alderaan for an unspecified duration, continuing until at least 3653 BBY. In that year, it accommodated the Alderaan Peace Conference, a gathering involving the Galactic Republic, the Jedi Order, and the re-emergent Sith Empire. Following the shocking report of the Sacking of Coruscant, the demeaning Treaty of Coruscant was formalized within its walls.
