Synopsis
The game serves as a prequel to the first game, taking place ten years before. The story focuses primarily on Terra, Aqua and Ventus, three young Keybearers from before Sora‘s generation, although the game also gives focus to the origins of Sora and Xehanort, delving deep into the mysteries of Xehanort’s bleak past and forgotten memories as well as how Sora and Riku came to wield the Keyblade in the first place.
