A demigod has been sent to a world where mortals have the ability to control the elements. A world that has been at war for a hundred years. A world in desperate need of a savior. What will happen when a son of Poseidon reaches the Four Nations? Will he be their savior? Or will he be the harbinger of a much darker future? A crossover between Percy Jackson and Avatar.
