There Is No End
One day, the princess died in a way that no one could figure out. That princess was called the Bringer of Darkness. She had been hated for centuries, but now Nyx had found a solution. If the bodies she inhabited suffered greatly, those bodies would eventually spread darkness and prevent daylight from reaching a particular area. And Nyx used this situation. The world was plunged into chaos again, but Zeus created the soaring country of Lighdark to solve this situation and, in his words, threw all abnormal beings into that country. All beings who managed to hide and did not show anything abnormal remained in the normal countries of the world and continued their normal lives, but none of them knew of Lighdark's existence.
