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

Tommy was just about to go to bed, when he heard a sound coming from his basement. He didn’t know what it was, but he knew he wanted to find out. He walked downstairs to find a portal leading to an unknown world. He stepped through it and found himself in a dark forest. He began to walk through the forest, when he heard a noise in the distance. He began to walk towards the noise, when he saw a group of orcs attacking a group of people. He ran towards the scene and helped the people defeat the orcs. After the battle was over, he walked back through the portal and went to bed. He was amazed by what he had seen and was eager to explore the world more.
