The galaxy considered nova crystals to be a valuable resource. It was once remarked by the youthful Ezra Bridger, a homeless youth native to Lothal, that possessing just one case of nova crystals would be sufficient to provide him with financial security for the rest of his days. The planet of Elphrona held deposits of these crystals at a location known as the Verdigris Hills. There was the possibility that Herbs that sprouted from these deposits could be consumed as food.
