The fluttering sounds continues; it sounds soft and almost gentle. As you open the lift, something quickly brushes by your face. It feels like a bug - and then a swarm of moths, which somehow had been trapped within this piano, all fly out rapidly, some of them definitely fluttering themselves right into your face. Moths won’t harm you, no, but the suddenness of it might be enough to spook you from looking further. Scared, are we?

But you must look further, for there is something curious poking out from within the hammer and the strings. It looks black, old, and possibly familiar to you. You have met this object once before….long ago, when you first came to Hogwarts. The flap of material flutters almost playfully.

Magic always leaves a trace, doesn’t it?
