It was a typical day at the office, when all of a sudden, Jimmie noticed a strange portal in one of the walls. He had never seen anything like it before, so he decided to take a look. As he stepped through, he found himself in a strange place, full of colour and life. After exploring a little, he found a treasure chest filled with gold, and then he realised that he could go back to the office anytime he wanted.Jimmie was amazed at how easy it was to use the portal, and he soon realised that it was a way to get to different places without having to travel long distances. He started using it to visit different parts of the world, and he never stopped being amazed at the splendour and beauty of everything he saw.
