You wake up in the dead of night to a knock on your door. You wonder who on Earth is knocking at this hour. Bypassing your sleeping family, you answer the door. There is no one there, but there is a beautiful golden key tied with white string to a letter engraved in black velvet. You wonder who would send you something so fancy and mysterious, especially in the middle of the night. Before you can tear open the letter, the key starts to glow and twirl, leading you toward the forest. When it finally stops, it arrives in a black door deep within the dirt. The keyhole seems to match, so you slip the key into the keyhole. The door opens, and you are blinded with light. when you can finally see again, you are on a stone path, leading to a building.
