Why not check out the mess here first?

You look around, seeing the remains and wondering what the occasion had been. Someone's birthday perhaps? Nearby, the broken carcass of a pinata lay, stomach torn open and a few pieces of candy still laying amid the sand. That aside, the town square was pretty much...
Wait! Your eyes catch sight of something, almost concealed from view by the sand a few feet away. It looks...silver?
As you move closer, the sun glints off it's shiny surface. You reach down and dig your fingers into the sand, pulling the metal object from the ground and sifting the sand from your hand through your half-splayed fingers.
When you're done, a shiny silver key lay in your hand, sparkling as though brand new. As you look the item over, a sudden, unexplainable shiver works its way up your spine.
