Here is a world from Subsector A of the Unknown Subsector, it is an artificial World.

It was a beautiful dream, the election returns were in and he was over the top, it was a historic campaign and the first for the business man, who up until now concerned himself primarily with building, hotels, apartment buildings and resorts, he was very good at it too, but this was his first entry into the political arena and his opponent was scandal plagued and pathetically weak, he was celebrating his victory with his family and campaign advisors, when the Secret Service Agent shook him awake. “Mr. President, Mr. President, please wake up.” The President found himself lying on the cold concrete of the capital steps, there was a podium above him with his family Bible, a Gutenberg Bible, on top, not that he read much if it, it was more of a museum artifact that he invested in and loaned out to various museums, but today it was brought out to his swearing in ceremony. The President propped himself up on his elbow stiffly, his back ached, “What’s going on Fred?” the President asked, then he looked around and needed no answers, everyone was on the ground or just getting up like he was, a few were standing. “Unbelievable!” the President said, “did everyone fall asleep during my swearing in ceremony? More and more of his staff were being woken up as the Chief Justice of the Supreme Court rose groggily to his feet as well, brushing off his black robes. The President scanned the skyline, the various building of Washington DC held their familiar shape, it was then that he noticed the swollen red-orange-yellow moon displaying a quarter phase near the horizon, the moon lacked the craters and mares that he was familiar with, and instead sported smooth lava plains, and dark volcanoes, it looked rather like pictures he’d seen of Jupiter’s moon Io. “What happened?” the President asked. The Secret Service called on his radio, rather slack jawed at the answers he was getting, “Mr. President,” he said, “Everyone was asleep, people were asleep in their cars, passengers were asleep in airplanes on runways, it’s amazing no accidents occurred!” “What could do this?” the President demanded. “We’re still finding out sir! My men and women are waking up, we’ll have answers soon enough.”
Later that day, the newly inaugurated President sat in the Oval Office, the President was looking at a picture of Niagara Falls, the park was in the foreground with some astonished tourists looking on, on the other side of the falls, the Canadian side, and there was just empty wilderness. His advisors showed him a picture of the Mexican Border, there was an American town on one side of the Rio Grande, on the other side was empty desert. The Secretary of Defense called him on the phone, “We have sent a Marine Expeditionary Force into Mexico, there are on the site of Mexico City, we’ve confirmed the GPS coordinates, there is nothing there, only empty wilderness, and some wild beasts like we’ve never seen.” An Air Force General called next, “We’re inspecting the site of JFK Airport in New York City, the buildings are different, and there are strange aircraft instead of the usual passenger jets, much like Reagan International and all the others.” An Admiral spoke next to the President, “All of our aircraft carriers are accounted for, we’ve sent expeditionary units into Spain, Morocco, South Africa, and China, and they are all telling us the same thing, there is no one there, no sign of human activity or presence, it seems we are alone on this planet, I’ve talked to some astronomers as well, the stars are all wrong, the planets are all wrong, our geologists have taken some seismic readings, and some large hollow cavities have been found miles below the ground! We can’t detect the Earth’s core, there is an empty hollow cavity a few thousand miles down, the seismic waves stop there and return, various regular support structures are all found beneath the ground. We’re not on Earth, we’re on a fake Earth, and we’re not even in our own Solar System!”
