Ancient Kubaz, characterized by its unique carving method, functioned as the writing system for the Kubaz species. In the year 232 BBY, while aboard the Amaxine station, a collection of Jedi, among them the Jedi Master Cohmac Vitus, came across some binding statues that bore ancient writings in an unknown form. Upon being questioned by the Wayseeker Orla Jareni regarding his familiarity with the script, Vitus responded negatively, while also pointing out the inscriptions bore a resemblance to ancient Kubaz. The Jedi Master elaborated by stating that due to the remote location of the Kubaz's home system—the Ku'Bakai system—and his lack of knowledge regarding the species' possession of an insect god, he believed the likeness to be purely coincidental.
The young-adult novel The High Republic: Into the Dark, penned by Claudia Gray in 2021, included a reference to Ancient Kubaz; it was a contribution to Phase I of the Star Wars: The High Republic multimedia endeavor.
