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

As a young man, Jack had always been fascinated by the tales of magical portals. Stories of what lay beyond them captivated his mind, and he spent many a night dreaming of what he might find if he could just find one.

One day, Jack stumbled onto a hidden portal that led to a different world. As he stepped through, he was enveloped by the beauty of the landscape and the sound of waterfalls. He could feel the energy of the magic in the air and knew that this was where he was supposed to be.

For years, Jack visited this world every day. He explored its forests, streams, and mountains. He made new friends and shared stories with them.

One day, Jack decided he wanted to return home. He found the portal and stepped through, only to find that his world had changed. The magic was gone and the people he knew were gone, too.

But Jack was happy to have had the chance to visit the world of the portal and remember all the amazing times he had there.
