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

One autumn day, a man found a strange portal hidden behind a bookshelf in his library. When he touched it, he was transported to a strange, otherworldly place. There he found a magical fountain that granted him three wishes.

The first wish was to be able to travel to any place in the world without having to worry about money or passports. The second was to be able to change his appearance at will, and the third was to be able to have any wish granted by the fountain.

Over the next few weeks, the man used his new powers to travel to new and exciting places. He also found new friends and fell in love. However, one day, he decided to use his last wish to travel back to the library. When he arrived, he found that the portal had disappeared. He was both sad and grateful that he had been able to use it to experiences all the wonderful places it had take him.
