The room was light and airy, with enormous windows lining each wall, though they were too frosted to see through. Along one wall were bookcases filled to the brim with defensive textbooks, and to the other were thick padded exercise mats stacked one on top of the other, with inactive training dummies lined up side-by-side, waiting to be called to action. At the furthest wall, was an elevated duelling platform complete with a shimmering protective barrier enclosing it. Harry expected it would be months before they found any use for it. And finally, tucked just beyond an archway at the leftmost corner, was a small classroom which included at least thirty chairs placed in a semi-circle around a small platform with a lecturing podium. Behind this was an empty blackboard, and a tall oak cupboard. Harry expected that anything he could possibly think of could be found behind the cupboard's doors.
