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

Jeff had always been a bit of a skeptic. He doubted the existence of all sorts of magic, from ghosts to fairies. But when he turned 16, he discovered a portal to a world of magic. He was excited at first, but as he stepped through, he realized that this was no magical world. It was reality. And the things he saw… The things he did… He couldn’t believe it. He was a wizard.
