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

Samuel had always been interested in the supernatural. He had always been a reader, and when he was older, he had started watching horror movies. Then one day, he discovered a portal to another world. He stepped through, and found himself in a place filled with magic. Everywhere he looked, he saw creatures that he had never seen before.

He explored the city, and found that he had a knack for making people do what he wanted. He quickly became powerful, and ruled over the city with an iron fist. But no matter how powerful he became, he could never escape the feeling that he was not truly living. He had found his true passion in the magic of the world, and he could never go back to the boring life he had before.
