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

It was a cloudy day, the kind that often precedes a storm. As he walked his dog along the river bank, John noticed a strange opening in the ground. Curiosity getting the better of him, he decided to investigate. After descending into the opening, John found himself in a strange, unknown world.

He passed through a series of swirling, golden portals, each one revealing a new scene or adventure. Eventually, he arrived at a large, shimmering sheet of water. After a moment’s hesitation, John stepped through the portal and found himself on the other side.

He found himself in a strange, unfamiliar city. He wandered through its streets, admiring the strange architecture and the colorful inhabitants. Eventually, John found himself in a large, open market. There, he saw a woman selling strange fruit.

John was curious, so he decided to buy some. When he reached for the fruit, he found he was unable to take his hand away. He tried to move, but found himself rooted to the spot. Panic setting in, John began to scream for help. But, before he could say a word, the fruit in his hand had changed into a necklace and was around his neck.

John was trapped in this strange world, where he would be a part of its inhabitants forever.
