The World of Nothing is a white, lifeless world, eaten up by the Void appearing in Super Paper Mario.
History[]
It is classified as Chapter 6-1 in the game. The World of Nothing is nothing but a long road ahead along with ruins of the former Sammer's Kingdom. Here the heroes face Mr. L, Luigi possessed by Count Bleck, with his new improved Brobot, for a Pure Heart that was destroyed along with what the world previously was known as Sammer's Kingdom.
After the game is beaten, the World of Nothing is restored back into Sammer's Kingdom, along with its citizens and its king, so the player can progress through this optional chapter.
