As you step through the Arithmancy classroom doors, the wooden desks and chairs have been arranged into two neat rows. Professor Shackleton sits behind her desk, her legs crossed and a glass of water in her hand. With her other hand, she is scribbling quickly on a piece of stationary parchment. Her owl stands atop the corner of her desk, preening itself while waiting for Macadrian to finish her letter. While taking a sip of her water, she reads over what she wrote and when satisfied with the letter's contents, she taps her wand to the parchment. Quickly it folds itself over twice and slips into a thick parchment envelope, which she ties to the owl's leg before sending it off out the window.

She then turns her attention to you, "Good afternoon! Take a seat wherever you'd like and we'll get started very soon."
