As the series of the Isle of the Four Kingdoms continues, Princess Toosweet Filly journeys to fulfill her destiny as sorceress and Guardian of the Blue Dragons, the Dragon Lady. Secluded on Dragon Mountain, she advances her sorcery knowledge and skills, having limited contact with her family and her fellow adventurers. Toosweet's best friend from their days at the Sorcery Academy, Sandy, has betrayed her, and Sandy's subsequent actions have split the two former friends, with Toosweet seeking justice for Sandy's action. But, Sandy has disappeared. Or, has she? Thinking that she has killed three of the four kings of the isle, Sandy seeks asylum in the remaining king's territory, the Kingdom of Stonebridge. Here she meets the man whom she sees as her destiny, Donald. Assuming the title of Lady Destiny, Sandy collaborates with Donald to achieve their goal of wealth and power through illegal means. Their methods, greed, and obsession garner them unwanted attention and bring them face-to-face with Toosweet and her fellow adventurers. What will decide the outcome of the duel between Dragon Lady vs Lady Destiny? Will it be the power of the dragons or the restricted items taken from the academy?
