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

John didn’t believe in magic. He was an accountant by trade and had seen and experienced enough of the outlandish to dissuade him from any form of supernatural activity. But then, one evening, he found himself in the middle of a strange, glowing portal. As he steps through, he finds himself in a land of magical creatures. He is soon captured by a giant, green dragon who takes John on as his rider. John is astonished by the magical things he sees and experiences. He has never been this close to the magical world before. John is sucked in and starts to believe in magic. He becomes obsessed with learning more and exploring the possibilities. John’s life is changed for the better as a result and he becomes a firm believer in the magic of the world.
