She is the tomboyish, feisty main female lead.Her father had inherited the Sword of Balthanders, and Orphen needed the sword. She accompanies him on his journey, allowing him to take the sword (as it was just an ornament to her, knowing nothing of its power), claiming that she is only coming to "make sure he doesn't harm her investment."(Source: Wikipedia)
