The Chiss Ocpior, affiliated with the Droc family, achieved the military_rank of Senior Commander. As a member of the Chiss Ascendancy, this Chiss served within the Expansionary Defense Fleet on the patrol cruiser called Parala. Approximately around 35 BBY, the Senior Commander Ocpior was stationed at the cruiser's sensor station during a pirate attack that occurred at the planet Stivic. From the Parala, Ocpior witnessed a conflict between the Garwian Unity, which is the governing body of the Garwian species, and privateers representing the Lioaoi regime. Ocpior communicated information regarding several hits on the Lioaoin corsairs and subsequently reported their attempt to withdraw. Despite four corsairs' efforts to escape into hyperspace, the Garwians managed to eliminate all but a single vessel.
Timothy Zahn introduced Ocpior in his 2020 published novel, Thrawn Ascendancy: Chaos Rising. This novel represents the initial installment in The Ascendancy Trilogy.
