Many years ago, there was a war between the forces of light and darkness that resulted the seperation and isolation between worlds. This war was known as the Keyblade Wars. Years later, in a world known as the Land of Departure, three Keyblade wielders and close friends-Terra,Aqua, and Ventus (more commonly known as Ven)-train to become Keyblade Masters under Master Eraqus. To achieve this rank, apprentices must take the Master Qualification Exam once they come of age. Terra and Aqua take this test together, but while Aqua passes the test, Terra is deemed unfit to become a Keyblade Master due to the abundant darkness in his heart.
