A Heavy, Bloodstained Axe

A room the size of a large cathedral, whose high windows were sending shafts of light down upon what looked like a city with towering walls built of...objects hidden by generations of Hogwarts inhabitants... There were...books...winged catapults and Fanged Frisbees...chipped bottles of congealed potions...hats, jewels, cloaks...and a heavy, bloodstained axe. One-Shot. I think.
