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

Josh had always been interested in the occult, but he had never believed in magical portals until he stumbled across one while hiking. He had never seen anything like it before – a circular opening in the earth, with a bright light shining out of it. He approached cautiously, and was about to step through when he noticed a small inscription above the portal. It said: “To enter, speak the words ‘open sesame’.” Josh was intrigued, and decided to give it a try. As soon as he said the words, the portal lit up and he was transported into the light.
