The heartless run unabated throughout the worlds. They feast off the hearts of the weak and the strong alike. Their power grows daily, yet they themselves have enemies. A new enemy called "Nobodies" has suddenly appeared. The Heartless and Nobodies fight it out over hearts and kill one another.
The Nobodies seem to be ruled by a mysterious group by the name of "Organization XIII". This black cloaked organization is mysterious in nature, their motives are unknown. They are seen wherever a powerful "Heart" is.
The destined keyblade wielders have started to appear and fight against this common threat. The Resistance as well is now a growing force in the worlds. Led by "Leon", they fight the heartless and nobodies alike. "Chasers" A mysterious unknown group has recently appeared and their intentions are unknown.
This takes us to now, where Radiant Garden is under threat of siege. A giant chasm in the sky has appeared and heartless flood from it, nobodies flooding from individual portals. They head towards Radiant Gardens civilians, whom all have powerful hearts. Their intent is clear, to take all of radiant gardens population and to leave Radiant Garden a shattered and broken world to be absorbed into the "End of the World".
Similar chasms appear over other worlds, already having absorbed Atlantica and Halloween Town. No one knows what has happened to the group of defenders in these worlds but every one hopes they are safe.
Your destiny awaits, Save the world or Destroy it. Sit back and watch your friends die, or save them with your own power. What will you do? Are you a heartless or a Shadow of yourself? A Destined Warrior wielding a keyblade, or a warrior of darkness. A member of Organization XIII or a leader of the Heartless? Do what you must do your destiny awaits.
