The Thelvin Order was a society founded on the planet Barundi. Their purpose and organization seemed unclear, but they were known to have their own language which was unique to their people and followers. At some point, several Barundi natives were taken from the planet and placed on an uncharted world where they were set to guard the Yavin Vassilika. When bounty hunters arrived to claim the artifact, they noticed that the natives still spoke in the language of the Thelvin Order of Barundi.
