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

The man had been walking for hours, across deserts and rolling hills, when he finally came across what looked like a normal door. He stopped and examined it more closely, taking in the intricate carvings on the wood. It looked like it had been closed for a long time, but maybe with a little luck, he could find the key that would open it. He tried the handle, but it was locked. He started to knock, but then he heard a noise behind him. He spun around, heart racing, but there was nothing there. He sighed and tried the door again, this time turning the knob. It opened, revealing a brightly lit room full of statues. The man stepped inside, his eyes wide with amazement. He could see images of people and landscapes in the carvings on the walls, and it was as if they were alive. He started to look more closely at the statues, and then he realized that they were moving. He gasped and started to back away, but then he saw something else. In the center of the room, there was a shining orb, and in the orb, he could see his own reflection. He gasped again and started to run, but as he turned the corner, he saw the door closing behind him, trapping him in the room with the moving statues.
