Years prior to the events of the game, the Kingdom of the Crystal Palace was conquered by an evil being named Zaras, who crowned himself king. Only Zap, a dog who served as a Keeper of the Crystal Palace, and Farron, the kingdom's infant prince, managed to escape. As the game begins, Zap explains to a now-teenage Farron that the time has come to retake the Crystal Palace, giving the prince one of three magical crystals that grant special powers to their user.
