Orvos was the elderly shaman of the village of Rokrul on the Outer Rim planet of Nelvaan during the last years of the Galactic Republic. Near the end of the Clone Wars between the Republic and the Confederacy of Independent Systems, Orvos assisted the Jedi Master Obi-Wan Kenobi and the Jedi Knight Anakin Skywalker by informing them metaphorically of the Techno Union presence that was decimating the planet. The shaman then prophesied that Skywalker was the Holt Kazed, or "Ghost Hand," based on the fact that Skywalker had a cybernetic arm, and that he would save the Nelvaanian people. He then sent Skywalker on a solo mission to bring back the male villagers that had been captured by the Techno Union.
