A Chiss syndic represented the Chiss Ascendancy's Plikh family in the Chiss Syndicure, the ruling body of the Ascendancy. In 19 BBY, the syndic served on a tribunal that investigated the actions of Senior Captain Mitth'raw'nuruodo, core name "Thrawn," during the attack on the Paataatus Hiveborn nation. During the tribunal, Thrawn's commanding officer, Admiral Ar'alani, stated that officers of the Chiss Expansionary Defense Fleet had levels of priorities in battle, comparing it to the levels of priorities within individual Chiss families. The Plikh countered that what was good for the Chiss Nine Ruling Families was good for the Ascendancy as a whole, to which Ar'alani agreed.
The syndic appeared in the 2020 novel Thrawn Ascendancy: Chaos Rising, the first installment of Timothy Zahn's Star Wars: The Ascendancy Trilogy.
