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

Greg had always been fascinated by the tales of magical portals and the amazing things that could be found on the other side. His parents had always warned him about the dangers of exploring them, but Greg was determined to find one for himself.

One day, while exploring the woods behind his house, Greg stumbled across a strange portal. He touched it, and then nothing happened. He tried again, and this time something strange happened: the portal suddenly opened up and took him inside.

Greg found himself in a strange world made entirely of light. He could see the beauty and magic of this place, and he was filled with wonder. As he walked through the portal, he realized that it would always be open for him to return.
