Our hero walks tirelessly along a path within a field and comes to a crossroad. Sora stands at the center of this crossroad and looks up at the night sky, thinking of the friends he has become separated from. A myserious man approaches from one of the forks and says "What you seek lies ahead. But you will lose something dear to obtain it." Only one path remains when the man disappears. Sora arrives at the gates of a curious building, Castle Oblivion, by following the sole path. What will Sora gain on this journey and what will he lose?
