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

George had always been fascinated by the legends and stories of magic. As a child, he would spend hours reading about spells and adventure, dreaming of traveling to other worlds.

One early morning, George was cleaning his garage when he found an old aluminum can. He wasn’t sure what it was, but he knew it was magical. George carefully opened the can, revealing a small, dusty key.

George didn’t know what to do with the key, but he knew it had to be kept safe. He placed it in a jar on his coffee table, and spent hours looking at the key, wondering what it could possibly open.

One day, George happened to glance at the key while he was cleaning the jar. He saw a tiny lightbulb start to turn on. He quickly looked away, but not before he saw a door appear in the wall next to the key.

George nervously approached the door, gingerly putting his hand on the knob. As soon as he touched it, the door slid open, swallowing him up into a dark, foreboding tunnel.
