All is calm and settled around the castle - at least as much as anyone can expect at Hogwarts. Perhaps you really are going to have that totally normal, completely quiet school year after all.

Well. Such a year will may come, but it is not this year.

A strange screeching, yowling sound, like a human caterwaul, can be heard echoing throughout the castle. Evidently, it's coming from this out of bounds area, though even stood here the squalling reaches your ears as though echoing through a long tunnel, and somewhat muffled by the door. Nevertheless, it is not what one might consider a particularly reassuring sound.

Perhaps you would be wise to follow instructions and stay away... or perhaps it's worth risking your neck (or, more importantly, your detention-free hours) for a quick, innocent, teeny tiny peek.
