arithmancy classroom

Around the corner from the suit of armor and adjacent to the gargoyle outside of the Headmasters' office is the classroom of Arithmancy. The well lit room, with easy access to Moaning Myrtle's abandoned bathroom, is identical to that of the History of Magic room. With three rows of desks facing the usually blank chalkboard, one would be surprised that the subject is far less dull than learning about the Goblin Rebellion. With wide windows and a magnificent view of the Hogwart's grounds, the method of fortune-telling based on names and numbers awaits you through the ever-open door.
