The Hidden Door

One day I found a hidden door I had never seen before. I decided to go through it when no one was to see what I could find. I was expecting maybe a dusty old attic at the most, but boy was I surprised. As I climbed through the door I noticed there seemed to be some natural light and not the dingy light I was expecting. As I gathered my bearings I wasn't standing on wood at all but grass. I appeared to be at the edge of a forest. Beyond this there was a clearing and off in the distance there were what appeared to be some structures. The buildings were on a hill, which made them look even more impressive. Leading down the hill were many steps. At the foot of the hill was a sitting area with stone furniture. There were chairs and what appeared to be loveseats, or in my world it would be called that. Which made me wonder where in the world am I? Or am I even on Earth anymore? Sitting on the furniture were a number of beings, they all weren't people, many looked liked creatures, creatures out of a fantasy. Elves and dwarves, angels, off in the distance I'm pretty sure I saw a unicorn and above everything I saw a pegasus flying. Wow this is to much to take in! Just then someone begins walking towards me dressed in a long flowing robe. I wonder what he could want with me?
