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

John was an average 28-year-old man until one day, when he stumbled upon a mysterious portal. As soon as he stepped through, he found himself in a different world. The first thing he noticed was the magical atmosphere. John had never felt so alive. He quickly discovered that this world was full of creatures like unicorns and dragons. John was so excited to explore this new world that he didn’t even notice the sudden darkness until he was attacked by a dragon. John was outnumbered and didn’t stand a chance, but he didn’t give up. He used his martial arts skills to dodge the dragon’s attacks and kill it with a powerful strike. John then discovered that he had the ability to conjure fire with his mind. This power helped him survive the night and make his way back to the real world. John’s experience was so exhilarating that he decided to stay in this world permanently. He now uses his magic to help people and fight evil.
