For generations, the Kingdom of El Callisto has prospered under the reign of King Callisto V. While the crown prince prepares to inherit the throne, the second prince, Orien, serves as the Commander of the Royal Knights, dedicating his life to protecting the kingdom from monsters. Everything changes when the king is afflicted with the White Withering Curse, an incurable disease feared throughout the continent. It begins with a fever and overwhelming weakness. Soon, white patches spread across the victim's body until every inch of skin turns pale. Once the transformation is complete, death is inevitable. Yet an ancient legend speaks of a single hope. Hidden somewhere in the world lies the Lake of Seven Curses, a mysterious lake said to grant eternal life and cure any disease to those who reach it. Refusing to watch his father die, Orien embarks on a perilous journey to find the legendary lake. Along the way, he must face powerful monsters, forgotten kingdoms, and dangerous secrets that have claimed countless lives before him. Will he find the legendary lake before the White Withering Curse claims his father's life, or will the legend prove to be nothing more than a myth?
