Svivren was a mountainous Outer Rim Territories planet not far from Andasala. It was at the terminus of the Five Veils Route, which connected it to Suarbi. Despite the harsh climate of the world and its severe seasonal variation, the native Svivreni thrived and made it an important regional trading port. Its population of more than eight billion included large colonies of Humans, Sullustans and Ewoks. The source of Svivren's Ewok population was unknown. The importance of trade was reflected in the planet's Festival of Great Trade. The planet was directly represented in the Galactic Senate.
