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

The sun was just peeking over the horizon, casting an orange hue over the land as Jack walked down the road. He had just woken up from his sleep, and decided to take a walk before starting his day. As he rounded a corner, he saw something that stopped him in his tracks. There, in the middle of the road, was a large, glowing portal. As he got closer, he could see that it was open wide, and a bright light was streaming outwards. Jack had never seen anything like it before, and was curious as to what could be inside. He decided to go inside, and stepped through the portal.

As he crossed the threshold, he was transported into a new world. He saw a beautiful, colorful landscape, with mountains in the far distance. He also saw a large, glowing tree in the center of the area. As he got closer, he could see that the tree was surrounded by a barrier of light, preventing anyone from entering or leaving. Jack was intrigued by this place, and decided to explore further.

He walked around the tree, and saw that there were several small openings in the barrier, allowing him to see inside. He saw that the inside of the tree was filled with small, glowing balls, similar to those that he had seen outside the portal. He was shocked by this discovery, and decided to take a closer look. As he leaned in, he saw that the balls were filled with a strange, blue liquid. He knew that he had found something special, and decided to keep exploring.

As he walked around the tree, he saw that there were several other portals leading off of it. He was excited by this discovery, and decided to take a closer look at each one. As he did, he saw that each one led to new, different worlds. He saw a world with beautiful, blue oceans, a world with towering mountains, and even a world with a giant, glowing city. As he explored further, he realized that these portals were the source of the magical light that he had seen emanating from the portal in the road.

He was amazed by this discovery, and decided to stay in this world for a while. He could not believe that he had found a place that allowed him to explore so many different kinds of worlds, all without leaving the comfort of his home. He was grateful for this magical discovery, and knew that he would never forget it.
