As a boy, Barry always believed in magic. He loved going to the library to read about spells and adventures. One day, while looking for a new book to read, he found a magical portal. Through the portal, Barry found himself in a different world. He was surrounded by strange and beautiful creatures who welcomed him with open arms. There was no fear in this world, only happiness. Barry was so enchanted by this place that he decided to stay. He continued to explore the portal and the world beyond it. Eventually, he met a beautiful woman named Sarah who told him about the darkness that was coming. Barry had to choose between the life he knew and what he now understood was an even greater adventure. He chose the adventure, and he never looked back.
