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

David was just about to go to bed, but something inside him was driving him to check one more time the attic. It was a habit he had developed over the years, ever since he found a portal in the attic when he was just a child.

It had taken him a long time to understand what it was, and when he finally did, it almost scared him out of his mind. But he knew there was nothing to fear, as the portal was nothing more than a simple door that led to another world.

And so, every day, he would go to the attic and explore the world beyond the door.

Tonight, as he reached for the doorknob, he sensed something was different. There was a feeling of peace and calm, as if the portal was always waiting for him to come find it.

Taking a deep breath, he opened the door and stepped through.

As he crossed over the threshold, he felt as if he had been transported to a different world. The air was cool and clear, and the stars shone down on him like diamonds.

He wandered around for a while, exploring the various magical places that lay waiting for him. And then, before he knew it, it was morning again and he had to return home.

But he knew he would be back soon, as the portal was always open to him.
