A collection of sectors could be found in the southeastern region of the Chiss Ascendancy, situated within the Unknown Regions. Among the planets located in these sectors were Celwis, Copero, and Sarvchi. Around 18 BBY, the Xodlak family, the Erighal family, and the Pommrio family assembled their respective fleets in this area as they readied themselves for the Hoxim incident. Not long after, also approximately in 18 BBY, a skirmish took place on Sarvchi.
