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

Simon had always been interested in the supernatural, and had always wanted to find a magical portal. While out walking one day, he happened to walk by a small hole in the ground. Thinking nothing of it, he continued on his way. But as he walked past the hole, something inside him compelled him to go down. He went down, and found himself in a dark, magical realm. There, he discovered a portal that led to other universes. As he explored these other universes, he realized that they all had similarities to his own, including a world where he was the protagonist. He decided to stay in this universe, and start a new life. Now, he travels through the portal to visit other universes, and helps people in them in the same way that he had been helped in his own.
