Joe was walking down the street, when he saw a strange light emanating from an old boarded up house. Curious, he walked up to the house and found a small door that led to a small room. Inside the room was a portal that led to another world. Joe stepped through the portal and found himself in a beautiful, pastoral landscape. He walked towards a large castle and entered through the front gate. Inside the castle, he found a group of people who were celebrating a birthday. Joe joined in the celebration, and soon he was swept up in the excitement. He didn’t know what to make of his new discovery, but he was enchanted by the adventure that lay ahead.
