Secret - Hidden place...

While exploring in town you notice a shadow disappear into a place between two shops. You are overtaken by your curiousity and follow after it, but for some reason it always manages to keep a consistent distance ahead of you. Eventually it vanishes and you find yourself in a dark alley alone in a part of town you don't recognize. At your feet is a sparkling pile of snow... Perhaps you will find something if you dig through it?
