Arli was a red ocean planet in the Outer Rim Territories. During the Great Hyperspace Rush, the planet was settled and had a hyperspace route mapped by the San Tekka clan, and a hardy was discovered on its islands that could be utilized in various materials. However, a more optimal location was soon mapped one star system over, and many of the settlers moved on, leaving the San Tekkas, who had made a home on the planet's moon. When the Nihil marauders established the Occlusion Zone, Arli was trapped behind the Stormwall. The Nihil prevented the moon's inhabitants from leaving, but they were eventually rescued by Jordanna Sparkburn and Cair San Tekka.
