The Grysk language served as the means of communication for the Grysk, a bellicose species that originated from the Unknown Regions. They employed a shared script for written communication. Prisoners of the Grysk race utilized their language to create encoded transmissions, and Commodore Karyn Faro informed Grand Admiral Thrawn that determining the extent of information conveyed within a brief time frame was unachievable. The individual known as "Jixtus" was a speaker of the language.
