Twilight in Porygonia

It was another lovely night in Ponyville. Twilight Sparkle was reading books in her library, finding new spells. She found an old book in one of the shelves. Its title is too faded to read. Twilight Sparkle began reading the book one page to another. The last page was blank. Twilight began reading the book from the first page again. There is a writing on the first page. It says, "GNIPEELSERAUOYELIHWTHGINTADNUORAREHTAGLLIWSNWONU". Twilight opened the next page. It says, "NWOTELOHWEHTREVOEKATYAMEZEERBMLACA". Twilight didn't remember having a book like this. She asked Spike, "Spike, do you know what this means?" But there was no answer. "Spike?" Twilight went upstairs to check on Spike. But no one was there. Twilight checked outside. Everypony was already asleep. Suddenly, Twilight heard a ring from outside. "What was that?" Twilight ran outside. It was quiet. No one was outside. Twilight heard a dull noise ahead. Twilight came closer. The noise was getting bigger, suddenly, there was a large shine right where Twilight was standing. The shine formed a hole, and Twilight was dragged inside. It felt like an invisible hoof was pulling Twilight inside the hole. Luckily, Twilight brought the book with her. After dragged inside, Twilight ended up in an unfamiliar place. It was daytime there. "Weird... why is it daytime all of sudden?" Twilight began looking around. "Wait, where am I? Where's everypony? What are these creatures?" Twilight began walking and looking at the tall buildings.
