A unique occurrence known as a Circle of Unity involved the congregation of the Nine Ruling Families' Patriarchs from the Chiss Ascendancy on Csilla, the Chiss capital planet. Near the conclusion of the Clone Wars, two Circles of Unity took place, marking the first such instances in a considerable time. The initial Circle authorized the Chiss Expansionary Defense Fleet's voyage to the planet Sunrise, the location of an unauthorized assembly of Chiss warships. The second Circle resulted in the exile of Senior Captain Mitth'raw'nuruodo, who bore significant responsibility for said assembly.
Each Patriarch had the allowance to bring one assistant, typically the Senior Aide to the Patriarch or the family's Speaker within the Syndicure. Nevertheless, on occasion, the Patriarch opted to include alternative family members, such as Syndic Prime Irizi'stal'mustro.
