The writing system employed by the Watith species was unfamiliar to the Chiss. This script appeared circa 18 BBY on the freighter Saltbarrel, belonging to Watith Captain Fsir, specifically etched onto electronic equipment containers.
The Watith writing was referenced within Thrawn Ascendancy: Greater Good, a 2021 novel and the second book of Star Wars: The Ascendancy Trilogy by Timothy Zahn.
