The Chiss Ascendancy's Nine Ruling Families included Brast'alshi'barku, a Captain of the Chiss. Each of the Chiss Ruling Families had a specific color association, and the family in question was linked to green.
In 27 BBY, Mitth'raw'nuruodo, a Force Commander serving in the Chiss Expansionary Fleet's Picket Force Two, seized the Bargain Hunter, a light freighter. Dubrak Qennto, a smuggler, captained the vessel, with Jorj Car'das and Maris Ferasi as crew members. Two Chiss warriors from the aforementioned family, identifiable by green shoulder patches on their black uniforms, assisted in escorting the smugglers onto the Springhawk, a cruiser under the command of Mitth'raw'nuruodo, who the smugglers knew by his core name, Thrawn.
The family maintained its standing until at least 22 ABY. However, they were not listed among the four Ruling Families in a report from the University of Sanbra during the Yuuzhan Vong War. They were also absent during a Jedi mission to Csilla in 28 ABY. This inconsistency was clarified in 35 ABY, when it was stated that five of the Nine Ruling Families had lost their power as a result of a civil conflict within the Chiss Ascendancy. This was not unprecedented, as the number of Ruling Families had historically varied between three and twelve.
