Known as the Demon Moon, was the largest of four moons that orbited the Outer Rim world of Onderon. Like its parent planet, its covered almost entirely by dense jungles that were populated by many species of fierce, predatory animals. Despite being temperate and habitable, the jungles of Dxun pose major challenges for everyone struggling to survive there. Due to its constant rains and wet climate, mechanical devices did not last long and required continuous maintenance.

One of three planets in the Onderon system, Onderon has a temperate climate, and is home to a primitive race of Humanoids. It has four moons. Dxun, the primary moon, orbits very close to the planet, allowing some animals to fly between the planet and the moon.
