Not being on school grounds officially the strix had shifted to his more natural form to get a bit of a stretch out of his wings (which were usually too inconvenient for school). He wasn't expecting to see anyone but some ghosts but upon instinct and hearing strange noises, immediately settled into hunting mode..
The room was something with a high cieling, something like a ballroom, and cobwebs hung and fluttered from unknown breezes. The strix nested on a beam in the dark heights and watched for movement.
It was stalking time.
