Anyway, moving on.
On a parallel Earth, known as Nightworld, live alternate races of all Earth creatures known as Endlings. Apart from the obvious visual differences, pure white or black skin, red eyes and jagged teeth, Endling are slightly stronger and faster than their counterparts in our world. In Nightworld most colours do not exist, everything is black, white or red, meaning the sky and sea are red, trees are black and the grass is snow white. Other than the physical differences, nothing is different, the world’s history is exactly the same as ours, as are the “people”.
