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

John was a regular guy who worked a 9-5 job and lived a fairly mundane life. He had never been much of a believer in the supernatural, but he was always curious about what could be out there. One day, he happened to stumble upon a small, hidden opening in the wall of his house. When he walked through it, he found himself in a strange, unfamiliar place. There was a beautiful, glowing portal in front of him, and when he stepped through it, he found himself in a completely different world.

John was awe-struck by the beautiful scenery and the magical creatures he saw. He quickly realized that he was in the middle of a battle between two powerful armies, and he decided to help the side that he felt deserved it more. After fighting tooth and nail to help his new friends win the war, John finally returned home to his regular life. But he never forgot the magical portal or the world he had found himself in. He sometimes explored the portal to visit his new friends again, and he always learned something new in the process.
