End of The World

The End of the World is a by-product of all Heartless's destructive nature. Although End of the World is the last world, the Heartless are not very numerous as compared to Hollow Bastion, but they are very powerful. Upon taking a world's heart, a tiny fragment of what is left of that world is sent drifting through the void of space until it eventually meets and merges with End of the World. It is, in essence, a Heartless of the destroyed worlds, as well as the location of Kingdom Hearts for worlds' hearts. In nature, it can be seen as the opposite of The World That Never Was, which is a similar artificial "Nobody" world without its own heart. A small fraction of this world, the Dark Wastelands, is where many mortal and non-darkspawn villains are sent to prison for their crimes against the worlds. In the Spongebob series, the End of the World is said in legend to be the location of the Third Cartoonian War, if it happens.
