The Helheimrungs were a mysterious group of people who lived in a small village nestled deep in the forests of northern Germany. Their name was a combination of Helheim, the underworld in Norse mythology, and the German word "Rung" meaning a secret or mysterious message. Their existence was shrouded in mystery and darkness, and their practices were often considered weird and cruel. The villagers living near the Helheimrungs' settlement avoided them, fearful of their strange practices and the strange aura that surrounded them. Those who ventured into the forests claimed to have seen strange rituals and heard the screams of animals being sacrificed. Some even claimed to have seen the Helheimrungs conducting strange experiments on humans. The truth about the Helheimrungs was unknown.
