Onderon was a lush planet in the Inner Rim Territories.
Onderon was a planet with four moons. Dxun, the primary moon, once orbited very close to the planet, allowing some animals to fly between the planet and the moon. The other three moons were Dagri, Evas and Suthre.
The native Humans of Onderon struggled against the beasts, eventually gathering new technologies and building a huge walled city, Iziz, to protect themselves. Like the people of many other fringe worlds, the Onderonians had a distrust of non-Humans.
