Graph markers were devices used by Chiss children for drawing that were available in different colors. In 19 BBY, the sky-walker navigator Ab'begh enjoyed using graph markers in her spare time aboard the Chiss Expansionary Defense Fleet warship Vigilant. While her fellow sky-walker Che'ri was staying with her aboard the Vigilant, the two girls used Ab'begh's graph markers, prompting Che'ri to wonder if her caregiver, Mitth'ali'astov, core name "Thalias," would get her graph markers aboard their warship, the Springhawk.
Shortly after, Che'ri asked Thalias if she could get her graph markers, but the caregiver was unable to do so before leaving for a mission, causing the young girl to grow angry with her. Prior to Che'ri's mission with Senior Captain Mitth'raw'nuruodo, core name "Thrawn," Che'ri asked him if he could get some graph markers before they left, and Thrawn assured her that he had already placed two new boxes on board their ship.
