The group of three Carrack-class light cruisers known as the Z-Pata group served under the command of the disloyal Grand Admiral Demetrius Zaarin during the Zaarin insurrection. Following the unsuccessful initial endeavor using the Nebulon-B2 frigate Z-Borus, these cruisers participated in a subsequent effort to seize the Vorknkx at the same location. Despite assistance from TIE/D Defenders and Gamma-class ATR-6 assault transports, the cruisers met their demise.
