Louisa had gotten aaaaaaaaaall the way to the top tower for Divination only to find the classroom, well, not there! She stared at the sealed door for a couple of minutes before descending the stairs to go to the courtyard to ask about the new-classroom..

..only she'd found it on the Ground floor.

The girl knocked on the door and peered in. The first thing that caught her eyes were the legs. She quickly averted her gaze to the Centaur and gave a nervous smile. "Umm... hello. D-d-do I enter?" Was there Centaur conviction in Hogwarts that she should know about? This room was sure their Divination classroom, though.
