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

In the middle of the woods, there was a large, black, gnarled tree. Beneath the tree, a man found a stone doorway. Curiosity got the best of him, and he pushed the door open. He found himself in a hallway with many doors. One of the doors had a sign that said “Spellbook Room.” The man took a step forward, and then he stopped. There was a loud SNAP! He turned to see a large, green, lizard-like creature standing in the doorway. The creature hissed at him and then disappeared into the room. The man took a step forward, but then he heard another SNAP! He turned to see a huge, green, snake-like creature poised to strike. He screamed and ran back the way he had came. When he got to the doorway, he saw that the lizards and snakes had already disappeared. He was safe, but he had never seen anything like that before. He decided to explore the other rooms.
