Prompt: Write a short story about a man who discovers a magical portal

Tommy was out for a walk in the forest one summer day when he came across a strange portal. He only had a moment to glance at it before he was sucked in. When he emerged, he found himself in a different world. The trees were different, the sky was a different color, and the people seemed strange. But he didn’t question it–he just went with the flow. He found himself in a strange city, where the people were dressed oddly and the buildings seemed to be made of some sort of strange metal. As he wandered around, he started to notice that there were similar portals all around the city. He started to explore, and soon he was lost in the city. He soon realized that he was in some kind of magical realm, and that he was the only person who could access it. He decided to stay and explore, and he has been living in the magical city ever since.
