As you step through the Arithmancy classroom doors, you see the room set up as it always is: neat and exactly-positioned rows of wooden desks and chairs, the latter of which have cushions in a myriad of colors and textures to match your comfort and liking. The walls are filled with thick wooden shelves, on which rest a seemingly endless number of Arithmancy texts and the occasional Ancient Runes and Divination reference.

Professor Shackleton sits behind her desk at the front of the room in lilac-colored robes, her skin a bit pale and her hair pulled back off her face. Her head is resting against the back of the chair and her eyes are closed, though she is clearly not sleeping. She lifts her head and opens her eyes to greet each of you softly as you enter the room and gestures for you to take your seat.
