Tommy had always been a little curious about the world beyond his small town. He was always exploring new corners of it, and one day, he stumbled across a mysterious portal. After stepping through, he found himself in a fantastical new world. He saw strange creatures and lush landscapes that he had never seen before. The portal was active, so Tommy was able to return to the town he had come from whenever he wanted.
