There was an unidentified desert in the interior of the lands of the state of Vadam on Sanghelios. In the House of Vadam's story of the ancient clan leader Ther 'Vadam, after escaping a rival kaidon who had seized control of the Vadam keep, Ther trained in the desert for many years. According to the story, there lived many other exiled Sangheili, reverted to mere nomads. These wanderers were considered "the least of the least", but Ther managed to make allies out of many of them. They later fought for Ther when he returned to the Vadam keep and recaptured it.
