The Cheunh script, which is occasionally referred to as Chiss Script, served as a writing system for putting Cheunh into written form; this was the main language spoken within the Chiss Ascendancy. Lieutenant Eli Vanto, after his inclusion into the Chiss Ascendancy, examined Cheunh script data listings while he was on the Steadfast. Certain Cheunh script fonts were intentionally created to be hard to decipher when viewed in reverse orientation, like from the opposite side of a table. The Pathfinder Qilori from Uandualon possessed a strong ability to understand Cheunh.
