As you step through the Arithmancy classroom doors, you see wooden desks and chairs arranged in a circle. Professor Shackleton has provided a number of cushions in a myriad of colors and textures that are stacked by the door for you to choose from to match your comfort and liking. Two walls are filled with thick wooden shelves, filled with a seemingly endless number of Arithmancy texts and the occasional Ancient Runes and Divination reference. The other two walls of the room are covered in framed pictures and posters of a very old man doing mathematical calculations, a map of the Mediterranean, a witch carrying a large wooden number seven, a chart converting letters to numbers, and many more pictures with a number at the top and people exhibiting various qualities below.

When you look to the front of the room, you see a tall, blonde-haired woman in emerald green knee-length robes sitting behind a desk made of dark angelique wood. On the desk is a small placard reading "Professor Macadrian A. Shackleton - Arithmancy," as well as a small stack of thin, leather-bound booklets, an assortment of papers and quills, several copies of the class textbook, and a small pouch that she keeps very close by her left hand. She smiles welcomingly at you as you enter the classroom and makes a small gesture for you to take a seat in one of the many desks in the circle.
