There is not just world but many. You probably already know this. However there is not just one universe but many. Familiar with the concept? Well did you know some of those universes are 3D printed copies of other universes?

That's because one universe has discovered a way to shrink planets down and serve them for consumption. This requires the creation of new universes. So WorldCorp began 3D printing any universe where a planet was consumed.

Because of this, the beings of this universe were known throughout the multiverse as World Eaters.

World Eaters looked human enough, though they had grey skin, red eyes and sharp teeth. Various governments within the multiverse have been trying to find ways to put a stop of the World Eaters, knowing that they could be next on the menu, but so far none have been successful.
