Full of squashy armchairs, tables, and a bulletin board where school notices, ads, lost posters, etc. can be posted. A window looks out onto the grounds of the school, and a large fireplace dominates one wall.

Accessed via ladder; round room that's lined with shelves: tea cups, crystal balls, decks of cards, etc. Oppressive fire with a copper kettle that gives off sweet-smelling fumes, and small round tables, squashy armchairs and little pouffes.

Thirteenth window from the right of the West Tower.
