Arli's moon was a moon that orbited the ocean planet Arli in the Outer Rim. During the High Republic Era, the family of Jordanna Sparkburn, a member of the San Tekka clan, resided on the moon. After the Nihil marauders established the Occlusion Zone, Arli's moon fell behind the Stormwall, trapping its residents, including Sparkburn's brother, Harth. The moon was also afflicted by what was known as the blight, which slowly consumed matter and drained the life from it. Sparkburn and Cair San Tekka visited Arli's moon to find the former's family, also learning of the blight. The pair rescued the remaining residents of the moon and took them to Seswenna, also delivering a sample of the blight to the Jedi Order.
