After winning over the medical experts of the Khuer tribe, Princess Rosemary von Velfalt can add "ending a pandemic" to her list of achievements. However, even this victory is not enough in the eyes of her father. Upon Rosemary's return home, the king has another seemingly impossible task waiting for her—venturing to Nevel's snowy northern reaches in search of the demon lord. Though the mission is both difficult and dangerous, there is one major perk: Rosemary will be accompanied by the dashing knight captain of the royal guard, Leonhart von Orsein! The pair journeys to a fortress commanded by Leonhart's old friend, but their search is fraught with hardship. Blizzards block their path, the temple they seek is nowhere to be found, and Rosemary must contend with the last of Hidden World's major NPCs—an assassin! Time to break another flag! The demon lord is out there somewhere. Can Rosemary locate this evil and unravel the cycle of resurrection once and for all?
