Dxun

Dxun, also called the "Demon Moon," is one of four moons orbiting the planet Onderon. Its thick jungles are home to numerous bloodthirsty monsters and, due to Dxun's erratic orbit, many of the creatures are able to migrate to the surface of Onderon during an annual period in which the two worlds' atmospheres intersect. Four thousand years ago, after the evil Queen Amanoa of Iziz was defeated by the Jedi, the inhabitants of Onderon built a Mandalorian iron tomb on Dxun to house the remains of their Queen and of the Dark Jedi Freedon Nadd. The fallen Jedi Exar Kun later visited the tomb, where the spirit of Nadd helped him discover some hidden Sith scrolls. Later, at the end of the Sith War, the warrior clans of Mandalore fled to Dxun after failing in their attempt to capture Onderon. Their leader was killed by a pair of the Dxun beasts, and a new warrior assumed the mantle of Mandalore.
