Two years after the events of Dream Drop Distance, the Darkness became so great that it swallowed the worlds, locking them away within its merciless abyss.

Twilight Town, now covered in eternal night, stands as one of last Sanctuaries of Light. It is where players begin their journey.

Ever resourceful, the Moogles have created a safe place for refugees. They have charged the Denizens of Light with finding Castle Oblivion: it holds a key to the puzzle of the lost worlds.

But within the dark shadows of the sanctuary world a powerful dark force still looms, waiting to strike.

Each survivor must choose whether to go to Castle Oblivion or stay behind to protect the world from the dragon that lurks in the shadows.
